By the time I reached the bra strap, I could smell Kaitlyn's excitement. It made me realize how far over the line was what I had done. I stopped immediately and looked across the room. Joanna had a smile on her face and seemed to be laughing lightly. Paul was holding her lightly and seemed to be talking to her instead of trying to learn what I was doing.
Kaitlyn shot up out of the chair and said loudly to Paul, "Let's go to our bedroom. Now." She held out her hand for Paul. Paul gave her an eager smile as he quickly crossed the room to her. They walked into their bedroom and slammed the door.
I saw movement and turned to see Joanna throw a towel over the couch. The bra was gone, and she quickly slipped off her panties. She lay down on the couch and said, "Eat me, Brandon."
I lay chest-down on the couch in front of Joanna as she spread her legs wide. I worked my tongue up and down her slit, getting her warmed up. Then I heard the first "Oh!" from Kaitlyn. Joanna put her hands on the side of my head and said, "Keep going, Brandon."
I did. I was so horny that I was definitely not going to stop. I was going to fuck Joanna as soon as I made her cum. I was going to give her a pounding tonight.
I danced my tongue up and down beside her clit. Joanna quietly gasped her pleasure. I adjusted the timing of my licks, so she gasped at the same time as Kaitlyn. Kaitlyn's loud moans came clearly through the wall, so it was like I licked Joanna to pleasure Kaitlyn.
Kaitlyn's moans suddenly stopped. I kept on lapping Joanna's pussy, giving her clit special attention. I could hear her deep breaths now.
Thump! Kaitlyn and Paul were fucking now. Thump! Thump! Thump! I wanted to join them. I wanted to fuck Joanna silly. I continued working her clit until she quietly came. I could barely hear her over the sounds of Paul and Kaitlyn fucking.
When Joanna recovered, I climbed above her and guided my cock to her pussy. Normally, I let her guide me in, but tonight I wanted to fuck so bad that I guided myself to her hole. A push, a push, and a third push, and I was buried all the way in. Then I started fucking her hard, pounding her furiously. Now, I could shut out the sound of Kaitlyn and Paul fucking. I was totally focused on slamming into Joanna. I desperately needed to release the sexual tension by cumming in her. I fucked her like a dog fucks a bitch in heat until I exploded into her so hard that I saw stars.
When I was finished, I collapsed onto Joanna. She hugged me tight and laughed lightly in my ear. "So mine and Kaitlyn's plan worked for you?" She laughed some more. I joined in. As no sound of sex was coming from the other room, I could hear her clearly now.
I said, "So what exactly was your plan?"
"That reminds me," she said as she pushed on my chest to get me off of her. I pulled out of her and got off of the couch. She sat up and knocked three times on the wall to Kaitlyn's bedroom. Joanna looked at me and smiled. "That's the signal we fucked. We don't want Kaitlyn storming back out here."
I used a corner of the towel to clean the juices off my cock. Joanna took the towel in one hand and my hand in her other before leading me to our bedroom. I pulled back the covers and we got into bed. We lay on our sides facing each other. I stroked her face and said, "Your plan?"
"Oh, yeah! Well, I told Kaitlyn that last night they were so loud while we were in the middle of foreplay that it took you out of the mood. And I expected the same thing to happen tonight if we didn't do anything different. I suggested they slow down so we'd be the first ones to start having sex. Kaitlyn said she didn't think she could get Paul to slow down enough. So she came up with the idea of us doing foreplay together as a way of getting both couples on the same timeline. Once the foreplay was done, I was to have you eat me and then fuck right away." Joanna gave me a naughty grin. "The noise didn't seem to bother you this time."
"No, it didn't. If anything, it made the sex better for me. And for you?"
"The same. It was like they were cheering us on."
"How far were we supposed to go out there?"
"Kisses and feels. We were supposed to do lots of kissing, but Paul went almost right away for the feels." A concerned look came across her face. "Kaitlyn looked so sad as she watched you give me neck kisses. I hope you didn't mind me having you do the same for her."
"I was fine with it. It was Paul I was worried about. I was afraid he'd get angrily jealous even though I wasn't kissing Kaitlyn on the lips or feeling her up."
"Exactly! I kept telling Paul that while you were kissing Kaitlyn. He wanted to switch back and make out more, but Kaitlyn had other ideas."
I laughed. "She did. It was funny to hear her say 'Now' and to see Paul hustle to obey." We both laughed. I kissed Joanna and my feelings for her swelled. I was tempted to tell her that I loved her. With my other girlfriends, they had said, "I love you" before I was ready to say it. I wasn't certain Joanna was ready to hear me say it, so I didn't.
Instead, I made a circle around Joanna's tit and said, "I think we have time for another round."
"Oh no. Paul is a one-and-done guy and I promised Kaitlyn we wouldn't do a second round."
I arched my eyebrow. "Where was this consideration for the other couple last night?"
Joanna chuckled. "We didn't ask for any consideration then. Kaitlyn did today." Joanna moved close to me, pressing her body against mine as she kissed me sensually. "But I could suck you off if you promise to not make a sound."
* * * *
I didn't sleep well again. This time, I kept waking up to my mind replaying me kissing Kaitlyn. Once again, I felt the texture of her skin on my lips, and I heard her gasps. I was hard all night long.
* * * * Chapter 2 * * * *
To save me some comments and PM's: I've always heard people use "laying out" for sunning. It's apparently an American-only phrase. I know that's grammatically incorrect, but it's what sounds natural to me.
The next day, Monday, was beautiful for water skiing, and we had a great morning session. When Mom or Dad skied, Joanna sat next to me, and Kaitlyn taught her how to be a good lookout.
After lunch, it was nap time for Mom and Dad, which meant the rest of us had to hang out somewhere else for at least an hour. What Kaitlyn and I usually did was lay out on chaise lounges that were halfway between the lake house and the lake. While Mom and Dad cleaned up, Joanna and Kaitlyn went into their bedrooms to change into sunning bikinis. The difference in how busty Joanna and Kaitlyn were was even more obvious when they were in these bikinis. Still, Joanna looked good.
Once we left the lake house, Joanna, Kaitlyn, and I went to the chaise lounges while Paul went over to a hammock in the shade with his tablet. We sprayed sunscreen on each other and then lay down. As I hadn't slept well the last two nights, I was soon fast asleep.
"...to you?" I heard Kaitlyn say quietly.
"Oh, yes. He's done it a couple of times," Joanna replied, also quietly. It was like my subconscious had heard I was being discussed and had woken me up. I continued to act asleep. "The first time he did it was before we fucked for the first time."
Kaitlyn gasped. "You've been fucking?"
Joanna snickered quietly. I thought they were being quiet to not wake me. "For weeks."
"Slut! Why didn't you tell me?"
"Because it was so fun seeing you get bent out of shape. Consider it revenge for all the fashion shows at work."
"Revenge? Did my showing off what lingerie I was wearing bother you?"
"Hell yeah! 'See what expensive lingerie my boyfriend bought me this week.' You know I don't have anything like that. All my underwear I buy on sale at Wal-Mart."
"I should have known, Joanna. I'm sorry. Forgive me?"
"Sure. Forgive me?"
Kaitlyn laughed. "Sure. Even?"
"Even."
There was a pause. I started to drift back to sleep but perked up again when Kaitlyn said, "Did it bother you when Brandon kissed me?"
"No," said Joanna like it was obvious. "It was my suggestion."
"Would you...would you mind if he did it again tonight?"
I had conflicting feelings about kissing and nibbling on my sister. Part of me thought it was wrong, but it was easy to dismiss that as no one else had been upset about me doing it. What I eventually settled on that it was a stupid thing to have done, but I had done stupid things before and would do stupid things again, particularly after a few beers, so there was no point worrying about it.
Joanna asked, "What would Paul think of that?"
"After we had sex last night, he made a joke about me liking my brother kissing on me too much. I told him that he'd better hope that Brandon did it again as he wasn't putting me in the mood for sex."
"Ouch!"
Kaitlyn said in an angry hiss, "Yeah." Then her voice cooled. "Paul's not going to do anything that could result in him being cut off." She sighed. "And I don't want to cut him off as it'll ruin the vacation for everyone else. But I can't count on him to put me in the mood. He's not good with foreplay; he always wants to go straight to sex."
"And Brandon kissing on you certainly put you in the mood." Joanna cackled quietly. "So you want to do tonight like we did last night?"
"Yes."
"Last night was fun. I've never done anything like that before but would enjoy doing it again." Then in a teasing tone, "I'm okay with lending my awesome boyfriend to you for a few minutes."
"Thanks," said Kaitlyn gratefully. After a few moments, she added, "Brandon's been a good boyfriend for you."
"A good mercy boyfriend."
Kaitlyn sighed. "He's not doing anything with you because I've asked him to. He wouldn't make love to you unless he cares for you. He genuinely likes you, Joanna."
"Then why does he always go out with both of us instead of just me?" Because we all have more fun when it's all three of us, and Kaitlyn doesn't mind being a third wheel. "Why didn't he spend more money on me? Take me to nice restaurants? Buy me nice lingerie?" Because I'm a struggling college student working a minimum wage job. "Why did you keep pushing him to make love to me?"
After a long pause, Kaitlyn said in a pained tone, "Brandon doesn't spend lots of money on his girlfriends. He shows his affection in other ways. And you can tell he cares for you in the way he looks at you and pays attention to you. Every girlfriend he's had has enjoyed having him as a lover. I wanted you to have a very positive lovemaking experience." Kaitlyn's tone lightened up. "Am I your best friend or what?"
"You are my best friend," replied Joanna with warmth in her voice. "Have been for years."
The girls moved on to subjects I wasn't interested in. I was angered and frustrated that Joanna still considered me a mercy boyfriend. What did I have to do to convince her that I cared for her? I had been as loving and as affectionate with her as I had been with any other girlfriend. I was suddenly very glad I hadn't said "I love you" last night. She probably would have not returned it, which would have made things very awkward.
* * * *
In the afternoon, we went jet skiing. While Joanna and I were riding a two-person jet ski, she told me about Kaitlyn's request.
I said, "Aren't you bothered by me lightly making out with my sister?"
"No! It was my idea. It was harmless fun. Last night was a lot of harmless but very exciting fun. Kaitlyn and I want to do it again."
I felt it was a stupid thing to do, that we could wind up embarrassed about it. But having a group make-out party twice was no more embarrassing than doing it once. "Okay."
* * * *
After jet skiing, we had a wonderful dinner and an enjoyable post-dinner conversation. When Mom and Dad left, Kaitlyn said, "Chairs like last time" before she and Joanna disappeared into her bedroom. I felt apprehensive. Though I had enjoyed last night, I couldn't shake the feeling it had been wrong. I felt like tonight was going to be more wrong since we were sober, and I knew I was going to be lightly making out with my sister in front of my girlfriend and her boyfriend.
Paul said, "I wonder what they'll wear tonight."
I shrugged. I tried to convince myself that seeing Kaitlyn in a bra and panties was just like seeing her in a bikini, but I failed -- bra and panties felt forbidden, which made seeing her in them very exciting. Then I shook my head; we were going to have some harmless but exciting fun, just like Joanna said. No one would get angry; nothing to feel embarrassed about.
The door opened and I turned to see the girls come into the room. Joanna led this time, dressed in the same bra and panties as last time.
Paul said, "Nice. My favorites."
Once I got a good look at Kaitlyn, I could see why the bra and panties were his favorites. They were a dark blue which looked great against Kaitlyn's skin. The bra had a circle close to Kaitlyn's neck, a circle beneath her breasts and a clear mesh connecting the two circles that had a plunging 'V' in the middle. The mesh lightly held her breasts, and they shifted noticeably as she walked. The mesh had stars scattered across, two of which strategically covered Kaitlyn's nipples. I could see all of her tits except where the stars were. The panties had an inch-wide ribbon of silk across the top with lace beneath. Right in the middle, the lace was missing and instead there was a deep V that must end just above her pussy. Any doubts about whether Kaitlyn shaved were gone. She looked sexy as hell in her outfit. Kaitlyn knew how to strut her stuff, and she oozed sexuality as she sashayed.
When the girls reached the space between Paul and me, they again stopped for a moment before Joanna walked sultrily toward me as Kaitlyn did the same toward Paul. I smiled at Joanna. She did look sexy as she walked toward me, even if she was the moon to Kaitlyn's sun.
I was ready with a kiss when Joanna slipped into my lap. After our first kiss, Joanna moved forward and whispered into my ear, "Lots of kisses tonight" before kissing along my jawline back to my mouth.
I was happy to comply. I loved kissing her. She had soft, full lips that felt great against mine. After a few kisses, I heard Kaitlyn say, "Not yet, Paul". I tilted my head enough so I could look over and I saw Kaitlyn pulling Paul's hands down from her tits. I sympathized with Paul -- how could Kaitlyn expect him to keep his hands off her tits when she was wearing that bra?
I pushed Kaitlyn and Paul out of my mind and concentrated on kissing Joanna. We kept kissing on the lips, but in slightly different ways that made the kisses hotter and hotter. Sometimes she'd grab my bottom lip between her lips as I pulled away. Sometimes I did the same to her. Sometimes I'd run my tongue over her lip as soon as the kiss ended. The whole time we were kissing, I kept thinking of Kaitlyn and Paul doing the same thing on the other side of the room. I heard another, "Not yet, Paul", but I was so into kissing Joanna that I didn't look this time. She was more aggressive in her kisses tonight than normal, like kissing in front of Kaitlyn and Paul was getting her extra excited.
I heard Kaitlyn say, "Stay here and, in a little bit, we'll go to our bedroom." I stopped kissing Joanna; she got up and walked toward Paul. I got up too, making room for Kaitlyn to sit down. As soon as she was seated, I kissed her neck. She let out a small gasp and grabbed my hands, pulling them to the bottom of her rib cage. As I did the kissing and nibbling, I moved my hands slowly in circles. To my surprise, Kaitlyn reacted more strongly tonight than she had last night, getting much more into the kisses and nibbles.
While I was kissing along Kaitlyn's shoulder, I looked across the room. Joanna was seated on Paul's lap, and Paul was running his hands up her arms to her exposed shoulders. Joanna gave me a smile. Paul looked bored. I kept kissing along Kaitlyn's shoulder. This time, I kept kissing once I crossed her bra strap and kissed all the way to the end of her shoulder. When I was done, I stood up.
Joanna was the one who got up immediately this time. She took a few sensual steps toward me with a big smile on her face before reaching behind her and undoing her bra. She kept her eyes on my face as she peeled the bra off her and tossed it aside. When she reached us, Kaitlyn got out of the chair and left my vision as I stared at Joanna in amazement. Joanna rotated the chair ninety degrees and ordered, "Sit down." I sat down in the chair. Joanna immediately straddled my lap. She grabbed my head in both hands and said loudly, "Suck it!" as she guided my mouth to her tit. Her nipple was already hard before it entered my mouth. I sucked gently as I grabbed Joanna's ass firmly in my hands. This was so fucking insane. Last night had been crazy, but this was even crazier.
I happily sucked on Joanna's tit while squeezing her ass until she pushed back on my head. She guided to me her other tit, and I greedily sucked on it too. Last night had been hot, but tonight was far hotter. I wondered -- had tit-sucking been a part of the plan? Something they had decided on while they were in the bedroom changing into bras and panties? Joanna had walked toward me topless with total assurance.
Joanna pushed back on my head and again I let go of her tit. She guided my mouth back to her first tit, and at the same time, shifted toward Paul and Kaitlyn so I could see them easily. Kaitlyn's bra was off, and Paul was furiously sucking on the right tit, which was closest to us. I was shocked to see Kaitlyn was red-faced with anger. What was she so angry about? Were the guys frolicking on second base in front of the other couple too much for her? Was Paul doing something that made her angry?
Joanna said loud enough for Paul and Kaitlyn to hear, "Paul said it was boring to watch you kiss on Kaitlyn. He asked me to do something he'd find exciting. Do you find this exciting, Paul?" Paul nodded his head vigorously while continuing to suck on Kaitlyn's tit. Joanna laughed. She ran her hands through my hair and said quietly to me, "I hope you find this exciting. I find it very exciting."
Joanna twisted my head gently, so I was looking at Paul and Kaitlyn again. Anger was gone from Kaitlyn's face and it was replaced by something I couldn't place, but it wasn't pleasure. Paul was sucking on the left tit now, giving me an unobstructed side view of the right one. I had known my sister was well-endowed, but it still shocked me to see exactly how well-endowed she was, how proudly her tit stood out on her chest. Her areola was a light brown and looked larger than average in size. Her nipple was completely erect.
Joanna said quietly to me, "I think Kaitlyn wants you to look at her tits. I bet it's making her very excited. I'm sure she's jealous that you're sucking on my tits instead of hers." Joanna added gleefully, "I love making her jealous."
After I had suckled on Joanna for a bit, I couldn't resist looking back over at Kaitlyn and Paul. Paul was mouthing her left tit again while Kaitlyn was looking at me. We locked gazes. As we continued to stare at each other, I saw out of the corner of my eye Paul bringing up his hand to Kaitlyn's near tit. He started playing with the nipple, running his finger around it and tweaking it. It was like he was showing it off to me. The whole time, Kaitlyn moaned as lust filled her face.
Joanna said loudly, "What are you going to do tonight to your naughty girl, Brandon? Are you going to give me a hard fucking?" Hell yes! An odd look came over Kaitlyn's face. "How are you going to fuck me? Doggie-style? Doggie-style on the couch?" I didn't care where or how we fucked so long as we fucked. I had never wanted to fuck so badly in all my life. I couldn't wait to get my cock in Joanna's pussy. The odd look on Kaitlyn's face became one of longing. "How about you throw me over the arm of the couch and take me there? Would you like to do that?" Kaitlyn appeared to whimper, like she wanted me to throw her instead of Joanna over the arm of the couch and fuck her.Kaitlyn pulled Paul off her tit. She jumped off the chair, so she was facing Joanna and me, giving me a good look at her tits. Joanna got up and faced Paul and Kaitlyn. Kaitlyn grabbed Paul's hand as she said, "Let's go!" and pulled him toward the bedroom. Paul took a good look at Joanna's tits before running off. We watched them cross the room to the bedroom and slam the door.
Once the door was closed, Joanna pulled off her panties. She walked quickly toward the couch and lay face down over the arm. "Fuck me, Brandon."
I was right behind her. I pulled off my shorts and quickly guided my cock into her hole. As she was bent way forward over the couch arm, her ass was way high in the air. As I made my initial push, I discovered Joanna was already very wet. I pulled back and then pushed my cock all the way in.
"Oh yes!" hissed Joanna. After I pulled back again, I slammed into her. "That's it! Fuck your naughty girl." I did, my body slapping loudly against hers each time I thrust into her.
"Oh, yes. I've been so naughty," Joanna mumbled into the couch.
"Does my naughty girl want a good, hard fucking?"
"Oh, yeah! Fuck me, Brandon. I want it bad."
I gave Joanna her wish, fucking her as hard as I could. The first time I had called her naughty, it had been just another way of teasing her, but I had known then that she liked being called naughty. Tonight, she had taken naughty to a whole new level, and I could tell she had found it very exciting. It had excited all four of us. I wasn't certain what I thought about Joanna enjoying being naughty, but I was too focused on fucking her silly to give it much thought.
It wasn't long before I could feel myself cumming. "Here it comes, my naughty girl."
"Give it to me. Give it to your naughty girl."
I pulled back once more before slamming into Joanna, firing a massive load deep into her pussy. I shuddered with pleasure as all of the sexual tension that had built during our joint make-out session was finally released.
It took me a bit to catch my breath. I was sweaty all over. I savored our fuck for a while before saying, "That was awesome, Joanna."
Joanna looked back at me and gave me a big smile. "I loved it too."
Joanna reached over to a towel on the coffee table and did her best to throw it to me. I pulled out and used the towel to absorb our juices. Joanna moved off the couch while holding the towel and pointed for me to sit down on the couch. I had a good idea of what she wanted, so I sat down on the edge. Joanna lay down with her head in my lap. She let the towel drop, exposing her pussy. "Now make me cum."
As I reached my hand toward her pussy, the thumps of Paul and Kaitlyn fucking started, with Kaitlyn moaning in time.
Joanna said, "Make me cum with your sister."
I slid my finger between her pussy lips and rubbed against her clit. Joanna hissed. I rubbed some more, and she was panting. She soon matched her pants with Kaitlyn's moans. I again had the feeling that I was making Kaitlyn moan as I fingered Joanna.
Joanna came before they finished fucking. After she caught her breath, she said, "Let's fuck in our bedroom."
We fucked with Joanna on top. The whole time we fucked, she'd occasionally mutter, "Fuck your naughty girl."
* * *
The next morning, Tuesday, I was awakened by Joanna amorously snuggling on me. Based upon the amount of light in the room, I'd guess we had fifteen to thirty minutes before Mom would knock on our door. Joanna and I couldn't have sex, but we could quietly make out. I tilted her head up with my hand and kissed her. The kiss morphed into a long, smoldering one.
Joanna said, "I had a great time last night. Did you?"
"Yes. It was crazy, but it was also crazy hot. You were incredible, my naughty girl."
Joanna smiled. "So you're not angry at me for being naughty?"
"No."
Joanna moved in for another kiss, which turned into another long, smoldering one. Joanna stroked my morning wood, making it even harder.
I said, "This is making me want to pee."
Joanna snorted. "Then go pee." She added sultrily, "I'll be lying naked on your bed when you get back." Joanna wore only panties when she slept with me, which meant she'd strip them off while I was gone.
I pulled on some shorts, went to the bathroom and came back. During my walk, I decided to discuss something with Joanna that was bothering me.
When I got back in the bedroom, the covers on the bed were thrown back and Joanna was lying naked on her back on a t-shirt. She wiggled her finger at me in a come here gesture. As I slid into bed next to her, I said, "Let's talk for a bit."
Joanna stretched sensuously like a cat and said, "Okay". She grabbed my hand and pulled it toward her pussy. "Talk."
"Do you think we crossed a line last night we shouldn't have? It was one thing for us to kiss and grope in front of each other but having the guys suck on tits is quite another." Particularly as I had watched my own sister getting her tits sucked.
Joanna maneuvered my index finger between her pussy lips and pushed up against it as she said, "It was a lot of fun, no one got angry or jealous, and all of us were hot and horny when we were done. I want to do it more. I think Paul and Kaitlyn want to do it more."
"Paul got to see your tits." I wasn't exactly jealous, but I would have preferred to keep Joanna's charms to myself.
"That was the point. He wanted me to make things more exciting, and I did by letting him watch us. Was it exciting for you to see Kaitlyn's tits?"
I struggled for an answer before getting distracted by Joanna moving her hips up and down, causing my finger to slide between her pussy lips. "Joanna," I said disapprovingly. She knew the rule about no-sex while my parents were around.
Joanna gave me a sexy smile. "I'll be quiet. I'm always quiet." She chuckled. "Unlike your sister."
I gave in. I lightly pressed down with my finger, stimulating the area around Joanna's clit.
Joanna said sultrily, "Was it exciting for you to see Kaitlyn's tits?"
Again, I said disapprovingly, "Joanna."
"Brandon, I won't judge you for your answer. Tonight, I want to do something like we did last night, and I want feedback as to what worked for you. Was it exciting for you to see Kaitlyn's tits?"
"Yes." I had loved seeing Kaitlyn's tits. They were the most beautiful ones I had ever seen -- just the right shape and size; wonderful skin; her areola were the right shape and color; the way they sat proudly on her chest. I was uncomfortable with how much I had enjoyed seeing them.
Joanna asked, "Did you mind my sharing you with Kaitlyn?"
"No." I had enjoyed it.
Joanna was pushing hard against my finger now and her breath was getting ragged. She said, "Good. I think my sharing makes her even more jealous." She went back to breathing deeply. I worked her clit as she liked, pushing her closer and closer. The only sound was Joanna's breaths -- she didn't moan or say anything. I surveyed Joanna as I pushed her closer to the edge; she was a beautiful, fun, sexy, naughty girl who knew how to make sex incredibly hot, and I was lucky to have her as my girlfriend. I moved my finger faster and faster, pushing her higher and higher. After a few minutes, Joanna clamped down on my hand with her thighs as she quietly came. Seeing her cum filled me with happiness.
Joanna pulled me to her. As she kissed me, she wrapped her hand around my dick. We kissed quietly yet passionately as she stroked me. She broke off the kisses and shifted to take my cock into her mouth when there was a knock on the door. Joanna gave my cock a quick kiss on its head and said, "I'll make it up to you later."
* * * *
Over breakfast, Kaitlyn suggested we go jet skiing this morning, and everyone else agreed. The cabin had two of the small one-person jet skis that you stood up on and two of the larger, two-person jet skis that you sat down on. After breakfast, Mom and Dad led the way down to the boat house where the jet skis were stored. Kaitlyn and I were right behind them, and the four of us were talking about what parts of the lake to avoid. When we got to the boat house, I turned and saw that Joanna and Paul were well behind us. They were engrossed in conversation as they slowly walked toward us. I had a bad feeling about them talking that way.
Kaitlyn said to me, "What do you want to start on?" I had turned to face Kaitlyn. "A small one or a big one? I think we should rotate the different jet skis among us, so everybody gets a turn driving each type."
I didn't answer as I was distracted by Kaitlyn's bikini top -- it was kind of a cross between the traditional bikini top and a crop top shirt. There was something about how Kaitlyn's tits pushed out their covering that emphasized their size. At the top center of her top was a peek-a-boo hole which gave me an enticing view of the top of Kaitlyn's tits.
Kaitlyn said, "What do you think of my top? It's new. I love how it feels and how it holds the girls in place." Kaitlyn shook her tits at me. It took every bit of restraint to keep my jaw from hitting the ground. "See? They barely moved."
I stood stunned for I don't know how long. I snapped out of it when Dad drove one of the big jet skis around to where we were and yelled, "Come on, kids. Let's go!"
* * * *
We spent the morning jet skiing, and all had a blast. We kept somewhat together, the two couples on the big jet skis regularly racing against each other, and the two people on the small jet skis doing likewise.
At one point, Joanna was driving a big jet ski while I held on to her. I asked her, "What were you and Paul talking about on the way to the boat house?"
"He thanked me for making last night exciting for him. And he asked me to arrange with Kaitlyn to do something similar tonight."
She seemed defensive, which annoyed me. Finally, I shook it off; I was making a mountain out of a molehill.
* * * *
After lunch, Kaitlyn, Joanna and I went to the chaise lounges while Paul headed to the hammock. The girls were wearing tiny bikinis, the same ones they had been wearing yesterday. Seeing them wearing so little was affecting me more today. After I had put sunscreen on Joanna's back, Kaitlyn said, "Would you please put sunscreen on mine? Paul's busy."
"I'll spray it on you."
"No one brought the spray," said Kaitlyn. "All we've got is lotion."
I had never applied sunscreen lotion to Kaitlyn before. I looked up at the hammock, and Paul was completely focused on his tablet. I glanced at Joanna, and she was already lying down with her eyes closed. Why not?
I squirted some of the sunscreen on to my hands and applied it to Kaitlyn's back. She pressed lightly back into my hands as I did so. Her skin felt so good and looked flawless. I was glad no one was looking at me because I had a massive hard-on. I applied the sunscreen as quickly as I could and when I was done, Kaitlyn said thanks. I arranged myself the best I could and lay down next to them.
The three of us chatted for a little bit about how much fun the morning had been, and then Kaitlyn dropped a bombshell -- "I'm thinking of breaking up with Paul when the week's over."
"You are?" I said. I discreetly looked up at Paul. There was no sign he had heard his name.
"Yeah. He's a great guy and I've loved dating him, but he drives me crazy at times. Last night was kind of the last straw."
My emotions churned in confusion. I couldn't tell if I was disappointed, sad, or happy that Kaitlyn was so close to breaking up. She hadn't announced she was definitely breaking up with Paul, so I interpreted her comment as a request for us to try to talk her out of it.
Joanna said, "Are you talking about him going for your tits while you were kissing?"
"No, though I was annoyed that I had to tell him twice to stop. This is probably TMI, but Paul is unimaginative about sex. When we're alone, he wants me to go down on him, then he does oral on me, followed by us fucking. He's good at oral -- he always makes me cum -- and he's a good fuck, but I'm tired of it being always the same. Last night, I wanted to skip the blowjob and go straight to him eating me out. I was ready to cum right away and fuck. But no -- I had to blow him first."
This was TMI, and I was a little shocked that Kaitlyn would graphically describe her sex life with Paul. But it was obviously bothering her.
Kaitlyn continued, "Paul is so different than any other guy I've dated. I've never had a guy shower me with gifts. And I loved it at first. I loved all the sexy clothes he bought me; I loved going to the expensive restaurants. But now monotony has set in. It's the same kind of gifts and the same kind of sex. My god, my closet is full of sexy dresses and expensive lingerie! I actually prefer it now when he sends a card." Kaitlyn was in the middle and turned toward Joanna. "I think that's why I put on the fashion shows at work; to get me excited about the latest lingerie Paul had sent me. I'm sorry it offended you."
"Forget it. I've already forgiven you."
"You're the best, Joanna," said Kaitlyn. "But back to Paul -- he's also too eager to have sex when we're alone. I kiss him and he starts pawing at my tits, just like he did last night. It was nice that I got him to slow down for a while. Last night's foreplay really had me fired up and I was so ready to fuck when we went to our bedroom." She paused for a moment. Picturing my sister being fired up to fuck made my head spin. "By the way, Paul wants the couch tonight." Joanna lightly laughed. "He somehow seems to have gotten the idea of fucking me over the arm of the couch." Joanna laughed some more.
The three of us were quiet for a little bit. I tried to process how I felt about Kaitlyn breaking up with Paul, but I kept coming back to Kaitlyn being fired up from last night's foreplay. A big part of the foreplay was me kissing and nibbling on her neck, and us locking eyes during the tit sucking. Was that what had gotten her so fired up? Was she trying to tell Joanna or me that her I-don't-know-what-to-call-it with me had gotten her so hot? The possibilities made my head swim.
Joanna finally said, "What if Paul learned to slow down? Would that make a difference?"
Kaitlyn shrugged. "Possibly. If he learned to slow down, I might be willing to keep going. And if he learned to be more creative. As I said, he's a considerate, caring guy. Why? Do you have an idea?"
"Somewhat. But first -- no bra and panties tonight. I'm tired of wearing a bra that is too big for me and makes my tits look tiny." Joanna turned to me. "Brandon, go jet ski. Kaitlyn and I need to have a serious girl talk."
* * * *
After lunch, we went skiing. When we got on the ski boat, Kaitlyn surprised me by sitting down next to me, forcing Joanna to sit next to Paul. It was far easier with all the noise to talk to the person next to you, so I talked with Kaitlyn. She was in a great mood, smiling a lot and laughing easily. Her "girl talk" with Joanna must have gone well. I kept an eye on Joanna and Paul while they talked. Paul was nodding his head a lot and occasionally would have a huge grin. I guessed their conversation was a part of whatever plan Joanna and Kaitlyn had come up with.
At one point, I asked Kaitlyn, "So what do you and Joanna have planned for tonight?"
She gave me a nervous smile. "Joanna wants it to be a surprise. It'll be fun. Go along with it, please?"
"What if I don't?"
"It depends on Paul. He's looking forward to having another night like last night. He told me so on the way to the ski boat. I don't know how he'll handle the disappointment of just being with me. Nothing could happen. Literally nothing could happen in our bedroom." The way Kaitlyn said it, I pictured them spending the night on opposite sides of the room, staring icily at each other. "Or we could have a big fight and break up."
"Are you that close to breaking up?"
"We were the first night here. Since we started having our little parties, we've pulled back from that brink."
I was torn. Last night, we had moved beyond what I was comfortable with, and I felt like tonight we'd keep moving past that line. I could say no, take Joanna into our bedroom, and everything might turn out fine. Or Kaitlyn and Paul could have a big fight, and we'd have a very ugly situation on all our hands. I decided it wasn't worth the risk. "Okay. I'll go along."
* * * *
When we got back to the lake house, Dad and I started working on dinner while Paul lolled on the couch with his tablet. As Dad and I made dinner, I noticed that, while Mom was showering, the girls went to Kaitlyn's bedroom and closed the door.
When Mom and Dad left, the girls disappeared into Kaitlyn's bedroom as I expected. Paul and I moved our chairs into their usual spots. Paul rubbed his hands in anticipation, so he must have had some idea of what was coming.
The door opened, and Paul and I turned to look at the girls. They were wearing terry cloth short-shorts and t-shirts they had cut off so we could see the bottom inch of their tits. As they walked, I was mesmerized by the sight of Kaitlyn's tits as they wobbled. Her t-shirt was thin so I could easily make out her nipple pressing against the material.
Kaitlyn was in the lead, and she stopped in the usual spot. When Joanna caught up to her, I was stunned to see Kaitlyn turn toward me. My eyes were wide in disbelief as she crossed the distance to me. She straddled my lap on the chair just like Joanna had always done. She said softly, "Joanna is going to teach Paul to keep his hands off her tits," and then her lips were descending toward mine. They seemed to move in slow motion for the last few inches. Did I want to kiss my sister? Should I stop her? I was frozen in place as her lips brushed mine. Electricity shot through me like I had been zapped by ten thousand volts. My heart was pounding in my chest. Kaitlyn had kissed me! The next kiss was a solid plant on my lips. Her lips felt so soft on mine. The kiss, combined with her sexy outfit, was intoxicating. I offered no resistance as Kaitlyn kissed me again and again.
I started kissing back. Passion rose within me as the surprise wore off, and I got into kissing Kaitlyn. She was beautiful, fun, sexy and smart. I had never thought about kissing her, but now I realized how much I had wanted to. Our kisses got steadily longer and more playful, with our lips grabbing and pulling. My hands moved up and down her smooth back, caressing her firm muscles. I stuck out my tongue and licked her lip. Kaitlyn pulled back and shook her head no before coming forward for another kiss. I took it that the rule for this part was no tongue in our kisses.
I don't know how long we kissed, but it seemed like an eternity. Each kiss was an experience I savored. As soon as a kiss ended, I replayed it over in my mind in the fraction of the second before the next kiss started.
I heard Joanna say, "You've been a good boy," and Kaitlyn stopped kissing me. I felt dazed, like the experience of kissing my sister was more than I could process. Kaitlyn smiled at me, turned and walked over to Paul, passing Joanna on the way.
As soon as Joanna was in my lap, she kissed me hard and pushed her tongue into my mouth. I quickly responded. Kissing Joanna wasn't new and exciting-because-it's-taboo like kissing Kaitlyn was, but Joanna made it hot by kissing me with such passion. My heart continued to pound. Joanna grabbed my hands which were on her back like they had been with Kaitlyn and she pushed them down. I dropped them down to her ass and squeezed; Joanna was wearing no panties. Joanna responded by rubbing her tits against my chest. We kissed in lots of different ways, sometimes with tongue and sometimes not but always frantically, like our kisses couldn't fully express our excitement for each other.
Eventually, I heard Kaitlyn say, "Switch back." Joanna hopped off my lap while continuing our last French kiss as she slowly pulled away. During our last kiss, I heard Kaitlyn say, "You were a very good boy." When Joanna broke off our last kiss, she headed toward Paul, and Kaitlyn was almost back to me. She said, "Neck nibbles."
I got up, and Kaitlyn sat down. I kissed her neck lightly, and she moaned. Again, she really got into my kisses and nibbles, moving to give me better access and then melting and moaning as I used my mouth on her skin. I felt like our kissing earlier had her more fired up for this than she had been last night. As I kissed and nibbled, I struggled with how much Kaitlyn and I were enjoying this; I knew we shouldn't be enjoying this as much as we were, but everyone else was fine with it so I didn't see any reason to hold back. But the internal struggle left me feeling dazed.
I kissed and nibbled my way down Kaitlyn's neck and toward her shoulder. I had to pull the shirt collar to the side to access her shoulder. I was so damn horny and couldn't wait to fuck Joanna silly. When I had kissed all of Kaitlyn's shoulder that I could reach, I looked over at Paul and Joanna. Joanna was lolled against Paul with her head resting on his shoulder. Paul's hands were lightly stroking her stomach. I realized then that with the crop top, Paul could have easily felt Joanna's tits while I was busy with Kaitlyn.
Joanna jumped up and held out her hand. "Come on, Brandon. They've got the couch tonight."
Sex with Joanna was incredibly hot as both of us were so fired up. It was like a wrestling match except we were co-joined in the middle. When we were done, I was physically and emotionally spent.
* * * * Chapter 3 * * * *
Wednesday, Joanna woke me by snuggling on me. When she saw I was awake, she gave me a kiss. "Had fun last night?"
"Mostly," I said with little enthusiasm. First thing in the morning was when I felt the worst about our evening activities. Joanna obviously didn't share my regrets or concerns. But then again, she wasn't making out with a sibling.
Joanna smiled. "I had fun kissing Paul. I hope that doesn't bother you. It wasn't anything serious to me, just some naughty fun. And it was what Kaitlyn asked me to do to try to improve things with Paul."
"How is you kissing Paul going to improve things between her and him?" The four us of switching for kisses wasn't sitting well in my stomach.
"Kaitlyn can't get him to listen to her about slowing down, but he listened to me. So now hopefully he'll go more slowly with Kaitlyn."
I didn't want it to make sense, but it did.
Joanna waited, as if she was expecting me to make a similar remark about kissing Kaitlyn. When I didn't make one, she said, "Look, I'm not going to judge you or Kaitlyn for what you did last night. I wouldn't have felt good about kissing Paul if you hadn't been kissing Kaitlyn. I would have felt like I was cheating on you. If it's not even, it's not fair." Joanna's face lightened. "An important part of my friendship with Kaitlyn is that we don't judge each other. She's okay with whatever I do; and I'm okay with whatever she does, including kissing you. And you did get her worked up with your kisses, which was the goal of last night." Joanna chuckled. "I could tell she didn't want to stop kissing you. But she had to because you're mine, all mine." Joanna chuckled some more.
Kaitlyn had been so eager to kiss me. And it had been so damn good kissing her...
I asked, "You're not going to tell anyone I kissed Kaitlyn, are you?"
Joanna snorted. "Of course not. I'd do nothing to hurt Kaitlyn. And when I talked about the plan with Paul on the boat yesterday, I made him promise to never tell anyone. Did you enjoy it?"
"What?"
"Kissing Kaitlyn, you idiot!" Joanna said with a smirk.
I didn't want to tell her yes, but I didn't want to lie. I went with downplaying the truth. "It was enjoyable. I would have never done it on my own, but I didn't mind it when she kissed me."
"The whole evening was enjoyable. I'm looking forward to doing it again tonight."
* * * *
We did jet skis after breakfast. At one point, Kaitlyn suggested she ride with me and Joanna ride with Paul. Once we were away from the others, Kaitlyn said, "Thanks for going along with everything last night. I think it was a good lesson for Paul. He was more flexible about having sex last night than he usually is. I hope you aren't upset about Joanna kissing Paul."
"I'm not. I'm not comfortable with it, but I understand why we did it. Joanna enjoyed it. She views it as innocent fun."
"Good." Kaitlyn gave me a squeeze. "Stop for a minute. I want to get wet."
I brought the jet ski to a stop. Kaitlyn jumped into the water and swam around for a minute. She then came over to the jet ski, put her hand on it, and looked up at me. I asked her, "What does Paul think of what you and I did last night?"
"He didn't say. He probably thinks it was disgusting and weird." Understandably so. "Was he bothered by it? I don't know. He's a very simple guy; as long as he can play his game and have sex, he's happy. I can tell he's enjoyed the fashion shows, and that he liked kissing Joanna. And we had awesome sex last night, which made him very happy. Did you and Joanna have awesome sex?"
I blushed a little. "We did."
"Great! Paul was probably too focused last night on having a good time with Joanna to have a reaction to you and me. And I don't think he'll say anything negative for fear that all of his fun at night will come to an end."
All of that made sense. Kaitlyn then did something I've seen girls do countless times - pull her top out for whatever reason. This time when she did it, she gave me a brief view of her tits. She was looking at her top when she did it, so she may not have realized I could see her tits. Or maybe she didn't think my seeing her tits briefly was a big deal after I had gotten a good look at them the other night. Part of me felt that I shouldn't look, but I couldn't resist looking as she had sensational tits. Her show was another one of the things that shouldn't happen that whose happening made my head spin.
I asked, "Are you thinking better about Paul after last night?"
"Too early to say. Paul is the first boyfriend that I've accepted as he is. Despite his flaws, he's a good boyfriend. But he's not a great boyfriend. If I knew of a guy who I thought would make a great boyfriend, I'd dump Paul in a heartbeat. What I don't want to do is dump Paul and then date a guy that I can manipulate without really trying."
"You're that manipulative?"
"I don't know if I'm so manipulative or if I'm so good at it." Kaitlyn's face turned very serious. "I've learned the hard way that you can't trick someone into being a better person, or into making the right life decision. I can't change people; they'll only change when they want to change. I've felt much better about myself since I started dating Paul because I haven't tried to change him. And I was open and honest with you and Joanna about why I wanted you two to date."
"Manipulating us into dating would have been bad."
"You say that, and I see how much happier Joanna is now that she's dating you. I took a big risk in asking you to date her."
Was she saying that manipulating was a good thing? "We would have figured out eventually that you had manipulated us, we would have been pissed at you and it would have hurt our relationship."
"And your relationship is great without me doing any manipulation?" That smarted. I opened my mouth to rebut her comment, but I couldn't think of one. Kaitlyn then said, "I used to think in too many cases that the ends justified the means. Or maybe I used to enjoy manipulating people more than I do now. I don't like it when I do it now."
"So don't."
Kaitlyn laughed. "Good suggestion. I try. Then things don't happen the way I want them to happen. Look at you and Joanna. Joanna won't accept that you're dating her because you want to. She thinks you're only doing it because of me. That drives me crazy as I think you're a great couple. It's the type of situation where I'm tempted to accept the ends justifying the means." Again, I had the feeling that she was a lot deeper than most other girls. She shook her head. "I wish now I could have had her come over when you were home, had you two hit it off, and then you decided to go out on your own."
"But that wouldn't have happened. I wouldn't have dated Joanna if you hadn't asked me to."
"Yeah. It's just that...I've come to realize that Joanna needs to make her own choices. Even if I'm totally certain about what she should do next, I need to let her come up with the idea on her own. Hopefully, at some point, she'll choose to let herself fall in love with you."
Another painful topic. "I hope so, too." But I had no idea when that would happen.
"Thanks for not judging me. I think there aren't many guys a girl could tell that she's very manipulative, and they'd not judge her for it. I haven't told Paul about my habit of manipulating."
I shrugged. "If I got angry at you, how could I date your friends?" Kaitlyn giggled. "Seriously, I've been hanging out with two non-judgmental women this summer, so I'm learning to be non-judgmental."
Kaitlyn climbed out of the water. When she got back up, I asked, "Don't you think it's weird for me to be getting you excited every night?"
Kaitlyn shook her head sadly, "I think it says more about how bad things have gotten between Paul and me that I find innocent kisses from you much more exciting than what foreplay he does." Kaitlyn grinned. "We're all having fun. For whatever reason, it's like we've all gotten blank checks, during that one hour, to have fun like we'll never have anywhere else. I'm never going to kiss you at home. Joanna is never going to kiss Paul after this week. I like the freedom we've been having, and I'm looking forward to more freedom tonight."
* * * *
When Kaitlyn and I finally got back to the rest of the group, Mom and Dad gave us disapproving looks for being gone so long. We were supposed to swap jet skis every twenty minutes or so, and Kaitlyn and I had delayed this swap. Paul and I hopped on the small jet skis and raced each other. We played for a while longer before heading back for lunch. The rest of the day was pleasant and completely normal. The only slightly unusual thing was that after dinner Paul volunteered to do all the laundry, and Kaitlyn asked Joanna to help him to make sure "he washes the girly stuff correctly".
I found the normality of it all disturbing. I had kissed my sister last night. I was going to kiss her again tonight. I felt like people should be acting differently because of it, but no one was.
As soon as Mom and Dad left, the girls went into Kaitlyn's bedroom. Paul and I got the chairs into position and sat down. I asked, "Did you have fun today?"
"I did". Paul winked at me. "And I'm hoping for even more fun tonight."
The door to the bedroom opened, and the girls came out again in crop tops and terry cloth shorts. Everything was basically a repeat of the night before - Kaitlyn came to me for kisses, Joanna came for French kisses, and Kaitlyn came back for neck nibbles. When I reached my usual stopping point, I looked up and saw Joanna lolling against Paul again. There was something about their familiarity that bothered me.
Paul called out, "Keep going!" and laughed. What an ass! I couldn't believe he wanted me to continue to make out with his girlfriend.
Then I had an idea - I'd get back at Paul by driving his girlfriend crazy. Suddenly, I wanted Kaitlyn to dump him in the worst way. I'd get Kaitlyn super-excited so the next time she was with the big doofus, she'd be so frustrated with his pathetic foreplay that she'd kick him to the curb.
I moved back up to Kaitlyn's neck and started kissing upwards from about halfway up. When I got close to her ear, I gently nibbled on her earlobe.
"Oh my God!" gasped Kaitlyn.
I inwardly smiled. I nibbled a few more times on her earlobe while I listened to her breathing quicken.
Kaitlyn gushed, "You're giving me goose bumps!" She sounded shocked at how much I was exciting her.
I blew softly in her ear and got another gasp. I went back for another nibble when I heard Paul say to me, "Check out her nipple!"
I looked down, and it was easy to see through Kaitlyn's thin crop top that her right nipple was completely erect. There was something about clearly seeing the outline of her nipple and that it was so stimulated because of me that greatly excited me. It looked so perfect, so inviting...
Paul said to me, "Go ahead and feel it."
I looked over and Paul had his hands on Joanna's tits under her crop top. Part of me was instantly jealous, but then it was like my hands moved on their own accord to slip under Kaitlyn's crop top. I gently cupped her tits and...
...I completely forget about everything in the world except Kaitlyn's tits. They felt perfect in my hands - just the right shape, the right size, and the right amount of heft. I savored their perfect-skin smoothness as my hands moved over them. I heard Kaitlyn suck in her breath. Initially, her left nipple wasn't fully erect like the right, but I quickly got it erect by tweaking it with my fingers. I felt like a kid in a candy store - that wasn't quite right, but it was close; I had the feeling that I had free reign to hold and squeeze something that I had deeply wanted to touch but had thought I never would. I had admired my sister's tits for years, and now I had my hands on them with her approval, and apparently the approval of her boyfriend and my girlfriend.
Kaitlyn turned and looked up at me, an inviting look on her face. I felt like I was falling as my lips moved slowly toward her. Down, down, down I slowly went until my lips touched hers.
My lips had barely touched hers before Kaitlyn pushed her tongue into my mouth. I opened my mouth wide and let her tongue in as I continued to squeeze her tits. This was so hot, so crazy; to be Frenching my sister like this. And she wanted it; she totally wanted me doing this - her tongue was dueling mine fiercely; she was pressing her tits into my hands; she was moaning every time I squeezed or tweaked. I was totally inflamed with lust, and I needed to fuck. I needed to fuck right now.
I broke off the kiss and looked over at Joanna and Paul. They were Frenching and groping like Kaitlyn and I were. Joanna must have noticed me looking at them as she broke off their kiss and stood up. She grabbed her crop top, pulled it over her head and threw it aside. She grinned mightily as she walked toward me while swaying her hips sexily. When she reached me, she took my hand and pulled me toward the couch. When we got to the couch, she pushed me to lie down the length of the couch on my back. She grabbed her shorts and slowly pulled them down while wiggling her ass. It was a crazy sex show. I stared at her neatly trimmed, dark brown bush while she slowly pushed her shorts to the floor.
Joanna stepped out of the shorts and climbed on to couch on her knees. She straddled my face and commanded, "Eat me." I stuck my tongue upward and parted her pussy lips. Her pussy was full of moisture - the wettest I could remember her being. I ran my tongue up and down the full length of her pussy, exploring how wet she was. I liked Joanna's taste and slurped up her juices as quickly as I could. I brought my hands up to cup Joanna's ass to help her balance. I'd done oral sex on Joanna many times, but this was the first time she had ever sat on my face like this.
As I slurped, I suddenly heard Kaitlyn's voice say, "Fuck, yeah!" Based on the loudness, she was close by - definitely not in her bedroom. With Joanna's legs pressed lightly against my ears, it was hard to place where the sound had come from. I gave Joanna a couple more licks before I heard Kaitlyn say, "That's it! God, yes. Lick me, Paul! I'm so damn wet!"
I pictured this part of the living room - the coffee table to my right was the center of the furniture here. Above my head was the TV and on the opposite side of the TV were two comfy chairs that had low, U-shaped backs and thick cushions to sit on. It was from there that I decided I was hearing Kaitlyn. Knowing that my sister was having oral sex and was probably naked so close to me drove me wild. I redoubled my efforts to make Joanna cum.
I made a series of quick licks around Joanna's clit as Kaitlyn continued to moan. I had no idea how I was doing as this was a new position, and I couldn't hear Joanna's breathing over Kaitlyn's loud moans. I took a break from focusing on eating Joanna out to look upwards. She was holding her upper body straight, and her body seemed so long from this angle. She had her right arm on the couch back to help her keep her balance. Her small tits really stood out from her chest. I took a mental picture and stored it away as one of life's precious memories before I returned my focus to making her cum.
As my tongue danced around Joanna's clit, I listened to Kaitlyn continue to moan. The two couples having sex like this was incredibly crazy; like something out of a porn movie. What would Joanna do once I made her cum? Would she fuck me in front of Paul and Kaitlyn?
Kaitlyn's moans got even louder. "Oh! Oh! Oh!" It was incredibly erotic to hear my sister's cries of ecstasy. She sounded close to cumming. I had no idea how close Joanna was, so I continued frantically working her clit.
I heard Kaitlyn yell, "Yes!" and then she was quiet. A few moments later, I heard movement from that part of the room. Were they going to fuck in the chair right next to us? Then I heard them moving away from us and the door to the bedroom close. Shortly after that, Joanna came, flooding my face with her juices.
After Joanna clambered off me, I sat up. Joanna grabbed her clothes off the floor and said, "Let's go to our bedroom." I noticed Kaitlyn and Paul's clothes were still strewn all over the floor. Joanna smiled and said, "They'll have to pick them up later."
* * * *
The next morning Thursday, I was awakened by the sound of someone entering our bedroom. I looked up to see it was Kaitlyn, dressed in her crop top and shorts from last night. Joanna was snuggled against me on the wall side, so I had an unobstructed view of Kaitlyn.
Once Kaitlyn saw I was awake, she said quietly, "Good morning!"
I shook my head. What was Kaitlyn doing in my room? She had never come into my room when I was with a girlfriend before. From the light, it was probably ten minutes before Mom would knock on our doors. As much as I loved my sister, I didn't want her to see me and my girlfriend in bed naked. It bothered me that another social rule was being broken. "What are you doing here, Kaitlyn?"
I noticed Kaitlyn had something in her hand, which she dropped on the floor. Joanna was awake now, and she partially sat up so she could see.
Kaitlyn said, "Last night, Paul got a look at Joanna's naked backside. I want to keep things even." With that, she turned around. She grabbed her crop top, pulled it off and dropped it on the floor. She grabbed her shorts and pulled them slowly down while sexily wiggling her ass like Joanna had done the night before. Joanna laughed good-naturedly. I admired Kaitlyn's beautiful ass as she put on her show. She was a curvy girl and had a full, nicely-rounded ass. Her firm ass cheeks practically begged to be squeezed. Kaitlyn has to be the sexiest woman in the world. Eventually, Kaitlyn was squatting on the ground. There was enough light that I could see her stepping into something. Then she was moving upwards, swinging her ass side-to-side again, as she slowly pulled up her bikini bottoms. When she reached her full height, she pulled the bottoms into position. In her hand was her top, which she quickly put on while continuing to face away from us. She gave us a look over her shoulder, smiled, and said, "See ya soon."
Joanna said, "Kaitlyn! I'd like to have a long talk with Brandon. Could you cover for me at breakfast?"
"Sure. Talk as long as you want." And then Kaitlyn slipped out the door.
I looked at Joanna. I was curious as to what she wanted to have a long talk about. Last night, we had crashed right away after we had fucked, so there hadn't been a chance to talk.
Joanna said, "I want to talk about last night. It went waaay further than I was expecting. While you were kissing on Kaitlyn's neck and shoulders, Paul asked me several times if he could feel my tits. I said no, that we could only do what you and Kaitlyn were doing. Paul told you to feel Kaitlyn's tits so he could feel mine. He was happy when he saw you kiss Kaitlyn as that meant he could kiss me. Everything had me so excited I had to have sex right there and then."
So Paul had been more than fine about what Kaitlyn and I had done. Probably thought it creepy but was happy to ignore what we were doing if he could do what he wanted with Joanna. I was not in a happy mood.
Joanna smiled at me. "I've said it before, and I'll say it again; it was all harmless fun. This morning, I wanted to tell you why I think that. I have three reasons, the most important of which is you're my guy; you're the one I want to have sex with, the one I want to sleep with, the one I want to wake up with, the one I want to have fun with." That made me feel warm all over. Joanna had never declared her affection for me so strongly before. "Reason number two is that I trust you and Kaitlyn. You aren't going to do anything to hurt me. Hopefully, you trust me to not do anything that hurts you."
I liked how this talk was going. "I do, Joanna." And then I asked, "Do you trust Paul?"
Joanna chuckled. "No. Well, sort of. I think he'll keep his word, but he's very aggressive about making out and will push things if he sees an opportunity to do so."
"Like last night."
"Yes. I'm glad you were there to keep him from going too far. But it doesn't really matter as he'll be out of the picture soon."
"Oh really?"
"Yeah. I watched him and Kaitlyn, and he doesn't excite her at all. I think she'd dump him this morning if there was some convenient way of sending him home. But there isn't, so she'll try to make their relationship last until we get home."
I nodded. That made sense, and I was glad that Kaitlyn would dump Paul soon.
Joanna said, "This week has been a perfect storm. I think whatever you and Kaitlyn do is harmless because I trust you, and I think whatever Paul and I do is harmless because I probably won't see him again after this week. And I think it's important that we switch partners up so Kaitlyn can be happy as she keeps their relationship on life support." Joanna smiled. "I like alternating as I have fun with Paul, and then I have even more fun with you."
I smiled at that.
Joanna tapped her finger on my chest and said in a light but commanding voice, "So don't expect anything like this to happen again. You're to never kiss another girl besides Kaitlyn, and you can only kiss her for the rest of this week. After that, you're my guy full-time. Understood?"
Exactly what I wanted to hear. I kissed Joanna and then said, "Understood."
"Good." Joanna smiled. "There's something else I wanted to discuss. The other day, when Kaitlyn was discussing how Paul bought her so much stuff, it probably sounded very mercenary to you; like she's only dating him for the money he spends on her. And now that she has so much stuff, she's lost interest in him."
I thought back to the moment. "It did sound that way."
"There are two reasons why a girl wants a guy to spend money on her. One is that she wants to raise her lifestyle. I've done that. I hate being poor relative to all of my friends. I've dated guys primarily because I wanted them to spend money on me."
"And they were jerks."
"The ones I dated were. But there are nice guys who are happy to spend money on you. There's a reason why young women marry rich guys who are old enough to be their fathers - financial security has a lot of appeal in a world where men have more wealth than women. If I dated someone like Paul, his willingness to spend money would go a long way toward keeping me happy. But I don't think that's what Kaitlyn is looking for."
This was interesting. "What is she looking for then?"
"I think she views Paul spending money on her as a sign of affection, and she's looking for an openly-affectionate guy. They have this great synergy in that he likes buying her sexy clothes, and she likes dressing up sexy for him. The Friday Paul was arriving to spend his first weekend, Kaitlyn was so excited about dressing up sexy for him that she couldn't resist sharing with the rest of us at the office. That was her first fashion show there." I wished I had seen it. "But Kaitlyn doesn't need expensive clothes to dress sexy. You saw that last night."
"I did. She looked very hot last night." I belatedly added, "And so did you."
Joanna rolled her eyes slightly. "So her not being excited about Paul now isn't due to how full her closet is." Joanna looked thoughtful. "Something has changed since the end of college. Any idea what?"
"No." I was a little surprised our conversation had taken this turn. "I spent very little time with them at school."
Joanna sighed. "Well, Kaitlyn will probably tell me everything next week." She started climbing over me. "Time to go help make breakfast." Once she was out of bed, she threw on her nightshirt and said, "I'm so happy now. I wish Kaitlyn was happy with me." And then she left.
I lay on the bed, thinking about our conversation. A weird side effect of our group make-out sessions seemed to be that Joanna was much happier with our relationship, much closer to saying 'I love you.' Was it because the sessions required me to trust her so much? Whatever it was, I felt good about last night's session even though Kaitlyn and I had gone way, way over the line. If everyone else was fine with it, why shouldn't I be?

When I came out for breakfast, Mom gave me a concerned look. Was she worried about Joanna and me having a long talk? Or did she suspect what the four of us were doing during her and Dad's walk?
During the morning's water skiing, Kaitlyn and Joanna regularly changed sides of the boat, and we guys almost always talked with whoever was sitting next to them. Kaitlyn was very happy when she talked with me. She didn't look happy when she was talking with Paul.
When the morning's water skiing was done, Kaitlyn had Joanna stay behind as the rest of us headed up to lunch. When the girls came into the lake house, they were giggling. Shortly thereafter, Kaitlyn told Mom that she and Joanna were going to go shopping after lunch and asked what was needed from the store. After Mom ate, she made a list and went over it with Kaitlyn.
I asked Kaitlyn, "Can I come with you?"
She gave me a smirk, and said, "No. It's a girls' shopping trip."
Once we were all done eating, I walked Joanna down to the minivan. She got in the passenger side, lowered the window, and said with an impish grin, "We're going to do some naughty shopping." She gave me a kiss, and then she and Kaitlyn were gone.

The afternoon wasn't much fun without the girls as I was beginning to loathe Paul. The girls didn't get back until almost time to make dinner. Over dinner, they were all giggles. Or Kaitlyn was all giggles - Joanna swung from giggling to being nervous or anxious. But both were giggling madly when they went to Kaitlyn's bedroom after Mom and Dad had left. Paul and I waited impatiently for the girls to come out as we didn't have anything to say to each other. As every other night, Paul and I were wearing shirts, shorts and no shoes.
The door opened, and I turned to see Joanna stride out. She was wearing white high heel shoes; red panties that were cut low at her crotch and high on her waist; a shiny, plastic black belt; and the only thing above the belt was a raspberry-colored beret. She looked super-hot. And then Kaitlyn came out behind her dressed the same and turned the hotness up to eleven. She had great tits and just a sexy air about her. Watching her walk had me rock hard.
Joanna and Kaitlyn walked to in-between Paul and me as usual, and I was mildly surprised when Joanna turned toward me. I heard Kaitlyn say to Paul, "Be a good boy and you'll get your reward later." And then Joanna was on my lap.
Joanna kissed me on the lips, and our kisses quickly became very hot; short kisses with lots of passion. It was weird that kissing my girlfriend was now a hot, novel experience, but this week was weird. I had no idea of what the limits were. With the way the girls were dressed, we were clearly getting crazy tonight, beyond what we had done before. I decided to stay with the same limits as the first round last night.
After a few minutes of kisses, I stopped and leaned Joanna back from me. I said, "What a naughty outfit." Joanna wore high heels to work, but she'd never worn them on a date with me. The panties and belt were gaudy and looked cheaply made. I suspected the girls tried to spend as little as possible on their outfits and had picked clothes they felt they would look equally good in.
Joanna blushed a little. "You like it?"
"I love it. You look so hot in it, so very naughty." Joanna beamed in pleasure. "You like being my naughty girl, don't you?"
"I like being naughty."
"You look good enough to eat," I said as I moved my mouth slowly toward her tit.
"Not yet," said Joanna as she intercepted my head and brought my mouth up for another kiss.
We kissed for probably another minute before Joanna stood up. She turned and walked across to Paul, and Kaitlyn walked across to me. If Joanna looked hot, then Kaitlyn was on fire. The belt around her waist and the high-cut red panties emphasized her narrow waist and curvy hips. Her perfect tits swung gently side to side as she sashayed over to me. My opinion that my sister was the sexiest woman in the world was reconfirmed.
Once Kaitlyn was on my lap, she leaned back to give me a good look at her. "You like?"
"I like. You're an incredibly sexy woman. You could make a blind man see dressed like that."
Kaitlyn laughed before coming in for a kiss. During our next kiss, I pushed my tongue forward between her lips and she eagerly opened her mouth to accept it, moaning once my tongue was in her mouth. I had been unprepared for Frenching with my sister last night, but I was ready and eager tonight. I knew it was wrong; I knew I shouldn't, but the other three were pushing me to do it and - damn it! - I wanted to do it. I loved it - I loved holding Kaitlyn close, the feel of her skin and most of all the sensation of our tongues frolicking together while our mouths were locked. I had never enjoyed kissing someone so much before. The kissing had my cock almost painfully hard. The wickedness of passionately kissing my sister in front of my girlfriend and her boyfriend while my parents were blissfully gone on a walk was driving me crazy. It was sick, weird and immoral, but it was also incredibly erotic.
Kaitlyn shifted her weight as she kissed me so that my cock was now pressing against her pantie-covered pussy. Had she intended that? No, she couldn't have intended that as this round was to be kissing with nothing sexual.
Then Kaitlyn shifted her weight again, rocking her hips forward to press more of my cock against her pussy. And then she rocked back, relieving the pressure. She continued lightly rocking back-and-forth as we frantically kissed. When I had thought kissing my sister was as hot as it could get, she managed to turn it up hotter.
Kaitlyn stood up suddenly. I could have kissed her for hours, but I knew she and Joanna had a plan for the evening. Were they even bothering to try to teach Paul better foreplay technique? I watched Kaitlyn's ass as she swung it slightly back-and-forth on the way back to Paul. The panties covered about half of her ass cheek, providing some shaping to an ass with great shape.
When Joanna straddled my lap, she said, "Hands, no mouth." I assumed she was stating the rules for how I could touch her tits.
"May I kiss?"
"You certainly may," said Joanna as she lowered her mouth toward mine. As we kissed, I brought my hands up, cupped her tits and gave them a light squeeze. We did a series of soft kisses that ended in loud smacks as I gently explored her tits. I didn't know if Frenching was permitted during this part, so I decided to let Joanna initiate any tongue. When I squeezed her nipples between my fingers, Joanna pushed her tongue against my lips. I brought my tongue forward and met her tongue outside of my mouth. We had a sort of sword fight with our tongues (a tongue fight?). It was silly and childish, and a lot of fun. After the extreme sexual intensity of making out with Kaitlyn, it was good to have fun. I felt a swell of affection for Joanna - she really was a great girlfriend.
I stopped the tongue fight, moved my hands aside and said, "You have wonderful tits."
"Kaitlyn's are better." Joanna was obviously bothered by her best friend's anatomical superiority.
"So? She has wonderful tits, and you have wonderful tits; just different types of wonderfulness. And your tits suit my naughty girl."
Joanna stood up. "Thanks." There was more sadness in her voice than happiness. I smiled at her, trying to show her how happy I was to have her as my girlfriend. I watched her as she walked over toward Paul. She had great legs - better than Kaitlyn's - and they looked even better in the high heels. She had a very nice ass. A little before she got to Paul, Joanna looked back and saw me looking at her.
Kaitlyn was by my side. To my surprise, she didn't hop on my lap. Instead, she looked back at Joanna and smiled; then turned back to me and said, "Stand up."
I stood up and looked over to see that Paul was doing the same.
Kaitlyn grabbed the bottom of my shirt and pulled it upwards. I bent forward so she could take it off me more easily. Once the shirt was off of my head, I looked over and saw Joanna doing the same to Paul. The girls dropped to their knees while looking at each other. They nodded to each other and turned back to their man. I looked down to see Kaitlyn grab my shorts and pull them down. She grabbed my boxers and pulled them down too. As I stepped out of them, I looked over and saw that Paul was naked like I was.
Kaitlyn stood up while pressing me back onto the chair. Once I was seated, she straddled my lap and kissed me hard on the lips. As soon as her tongue was in my mouth, I squeezed her tits. The sexual intensity was back up to eleven. Kaitlyn broke off the kiss, put her hands behind my head and hissed, "Suck them!" as she pulled my mouth to her nipple. Kaitlyn moaned as soon as I started sucking. I felt like a starving baby who was desperate to nurse.
"That's it, Brandon. Suck on my tit." Kaitlyn ran her fingers through my hair as she kept up a quiet monologue. "It feels so good. I've been wanting you to suck on my tits since I watched you suck on Joanna's tits while Paul slobbered on mine." Her fingers running over my scalp were giving me thrills. "Oh, yeah. I so like that." I stopped sucking on Kaitlyn's tit and instead kissed around her nipple, giving a little suck with each kiss. "Damn that feels good, you sneaky bastard. You don't know what you do to me, Brandon. I love it. I love the feel of your mouth on my tit. Time to suck on the other one." Kaitlyn shifted me to her left tit. "You've got me so excited, Brandon. I'm probably sopping wet."
Kaitlyn shifted her position and again my cock was pressed against her pussy. She started rocking her hips back and forth, grinding her pussy against my cock as I sucked on her tit; only the thin material of her flimsy panties was keeping us from having sex.
Kaitlyn said in a quiet voice full of passion, "I want to fuck you, Brandon. I want to feel your dick inside of me. I want you to make me moan, make me scream. I want you to cum inside of me, to fill me with your cum."
I couldn't take it anymore. I pushed Kaitlyn off of me and stood up. I had to end it now or I'd be throwing Kaitlyn down on the couch and ripping her panties off. I looked over at Joanna and Paul - Paul was slobbering on her tits enthusiastically while Joanna was running her fingers through his hair. It took me a moment to catch my breath enough to say, "Joanna, let's go to our bedroom."
I held my hand out to Joanna as I started walking toward our bedroom. She hopped off of Paul and walked quickly over to join me. I couldn't look at Kaitlyn - she had pushed me past what I could take from her, and I had to get away.
Once I had closed the door, Joanna dragged me by my cock over to the bed. She sat down on it and took my cock into her mouth while I stood. She bobbed two or three times before I exploded in her mouth. I came and came and came. I didn't know I could make so much cum. Joanna kept bobbing her head, sucking it all down.
Once I was spent, Joanna moved back on the bed and started removing what little she was wearing. "Someone was excited. Did you have fun with Kaitlyn tonight?"
I saw no point in denying it. "I did. That was crazy. Too crazy. Did you have fun with Paul?"
Joanna was naked now, and she patted on the bed for me to join her. "I did. I was very naughty with Paul tonight. He wants to fuck me. Do you want to fuck Kaitlyn?"
I felt like a huge pit had opened up in front of me. That was the obvious direction our make-out sessions were going. And Kaitlyn had enthusiastically endorsed the idea of me fucking her. "I can't, Joanna. She's my sister." I closed my eyes. It was painful to think this hard about the subject. "It's wrong. And what if our parents found out? Or people at--"
Joanna put her hand on my leg and said, "Relax. I'm not asking you to fuck Kaitlyn. She and I agreed before tonight that we'd never have sex with someone who wasn't our boyfriend; no oral either way and no fucking. Tonight was probably as far as we'll ever go." Joanna's hand slipped up my leg and grasped my cock. "So I'm asking you a hypothetical question; do you want to fuck Kaitlyn?" My cock started stiffening as she stroked it up and down. "Do you wish you could fuck Kaitlyn, even though you can't because she's not your girlfriend?"
I couldn't avoid the truth. "Yes, I wish I could fuck Kaitlyn. I'll never do it, but I definitely want to do it."
Joanna released my cock and swung her body over mine. I was lying on my back and now her crotch was on top of mine.
I asked, "Are you happy with that answer?"
Joanna positioned her pussy lips on top of my cock and started sliding back and forth on my cock. She looked down at me and smiled. "I am. I'm glad you're so honest with me." Joanna partially sat up, putting her hands on my chest and leaning on me so she could slide her pussy more easily up and down my cock. I was completely hard again. She just smiled at me as she continued gliding her pussy back and forth. And then she stopped gliding and rose up on one leg. She grabbed my cock and guided it to her pussy before slowly sinking down on it.
Once I was fully embedded in her, Joanna said, "Now fuck me like you want to fuck Kaitlyn."
* * * * Chapter 4 * * * *
I drifted through Friday morning. My sister had told me in no uncertain terms she wanted to fuck me, my girlfriend had weaseled out of me that I wished I could fuck my sister, and they were all smiles and laughter this morning. Paul was all smiles too, laughing and cutting up with them.
We water skied, and I skied miserably when I was out on the water. When Mom or Dad skied, thankfully Kaitlyn steered with Joanna as lookout as I would have been a nautical hazard. I mostly stayed close to the lookout seat though facing away so Mom couldn't see my face, and I did my best to look cheerful while my brain struggled to process last night. What stuck out was how much more aggressive Kaitlyn had been. Before last night, I could write off everything Kaitlyn and I had done as innocent fun. There was nothing innocent in how she had acted last night. I tried to think of reasons for the change and came up with nothing.
