Long seconds went by, minutes maybe. I was thinking about grabbing my bed sheet from the floor to cover myself from the cool air, despite mom's instructions, when the door finally opened.
I closed my eyes and kept my breathing slowly as mom walked carefully back to my bed. She seemed to just stand there watching me. When she spoke, I realized I had been wrong.
"Holy shit..." My sisters voice said, full of awe.
I was shocked. I almost panicked and gave myself away before I realized she thought I was sleeping. If anything she was in the wrong for walking in on me sleeping naked.
"Holy shit," she repeated, "I can't believe she did that to you..."
Wait, what? She had seen that?
"Jesus... That's so... She's such a..." She trailed off.
I carefully opened my eyes just enough to see. My sister was indeed standing to the side of my bed, watching me. She was wearing a long t-shirt and probably had her underwear on beneath.
She didn't look as horrified as she sounded though. Her eyes seemed to be glued to my now growing penis and she rubbed her inner thigh unconsciously with her left hand.
"You're still dreaming aren't you?" She said cautiously and turned to study my face.
I kept my face neutral and rested as I slowly closed my eyelids the last bit. In the dim light of the room there was no way she could have noticed I was awake. I was pretty good at faking it after all.
Not before she put a hand on my stomach did I carefully open my lids enough to see again. This all seemed very familiar. Did I dare hope to know were this was going?
"It's still wrong... isn't it?" She whispered, but I noticed a note of lust in her voice.
She was staring straight at my now nearly fully erect cock as she stood in silence, making little circles on my stomach with her fingers.
I took this time to appreciate how beautiful she was, even with that baggy t-shirt on her. That golden blonde hair, her lean form and long naked legs. Sis moved her hand to rub herself through her panties. She seemed to unconsciously bite her lip as she stood watching me. Before long she was moaning softly, her cute voice only making my dick harder.
I almost sighed in relief when she moved her hand from my stomach to carefully take hold of my shaft. Her small hand around my cock made it feel bigger than ever before.
"Holy shit, Bro..." She repeated once again, more awe and lust in her voice.
She kept working herself through her panties with her left hand while she held my cock in a determined grip with her other, carefully moving it up and down. Her soft moans were filling the room.
It didn't take too long for my sister to cum. She let a high pitched whimper escape her lips and bent over slightly, then took her hand from her underwear to put it on my leg for support. She breathed heavily and got down on her knees beside the bed, head resting on the side of the mattress.
"Fuck..." She breathed. "Fuck, fuck, fuck." She swore.
She eventually looked up again, to find my still very erect cock laying in front of her. Please... I thought. Fucking please.
I almost thought I had developed psychic powers when she leaned forward as if on command with her mouth open and closed her lips around my cockhead in one move.
"Mmmf." She let out as she gave me a very inexperienced blow job. She didn't move her tongue and only held her lips locked around me while she moved her head. Regardless, because of who it was and the still amazing feeling of my sisters warm mouth on my cock, it got me close to orgasm very quickly.
I came in the middle of her pushing down on me again. That obviously startled her as she pulled away instantly.
"Mmmfff! Bleh..." She let my sperm fall out of her mouth. What didn't stay on her chin landed on the sheets and on me. I was left to unload the remaining semen on my stomach, feeling good but a bit disappointed.
"Oh, crap!" She said as she noticed the mess. "Oh no, no, no." Sis said with panic in her voice.
She got up and ran out of the room, coming back with wads of paper which she immediately used to clean it up.
"Umm... that should be fine. Yea... yea it has to be." She said once she had cleaned me and thrown away the paper. "Oh my god..." Sis put her forehead back on the side of the bed and sighed, her fears put at ease.
She took my bed sheet from the floor and tucked me in. She kissed me softly on the cheek and whispered as she stood up.
"It's better if you don't ever find out about this Bro..."
Sis turned around and walked out the door, leaving me in my bed. I wanted to pinch myself. Holy fucking shit I thought. How the hell had I gotten so lucky?
Before long mom snuck back in to find me staring at the ceiling, thinking about threesomes and if the universe would punish me for my hubris for daring to even consider such things.
"Soooo, how was it?" Mom asked with a wicked smile.
"Uuuh, what? You knew?!"
"Of course I knew, sweetie." She answered and lay down with me.
"But how?" I asked. "How did you get her to..."
"Get her?" She laughed. "I didn't. I just noticed someone was watching us, trying to stay hidden." She explained patiently. "And she wasn't moving or calling out, so I just figured..."
"You figured she would walk in and suck off her brother? Really? How the hell would you know that?"
"Oh, sweetie." She trailed her fingers along my chest. "Just cause you fooled me once doesn't mean that your mother doesn't notice things. Haven't you noticed how she is always touching you, and gets upset when I challenge her for your affections?" Mom looked at me with an understanding smile as my eyes gave away my answer.
"Well, I suppose you don't really have anything normal to compare her behavior to. Seeing as your mother also wants to fuck you." She teased.
"Besides, " she continued, "your sister doesn't have any classmates or friends named John whose name she would be moaning in the shower. And yes, I've checked. Only you, her sexy brother." Mom poked me and her smile went wide as my eyes did the same.
"Wow... really?" I said in disbelief.
"Yes, so... what do you think about that? Think I should share you with her?"
"Hell yes!" I blurted out. "Uh, I mean if that's what you want... and she wants, and... it's okay?"
"Hah, don't worry Son. I don't mind. In fact, I think the idea turns me on." She purred and trailed her hand sensually over my chest.
"We are going to have to encourage her to continue what she did tonight though." She whispered as she lifted and removed the sheet between us. "I think it might be fun."
I was certainly on board with that idea. I had a good feeling about were this was going.
"You think you've got another one in you tonight?" Mom asked and looked at my dick.
"For you, Mom? Always." I smiled.
I sat up, being tired of laying still, and flipped mom in under me. I still needed time to recover so I moved down to her thighs and kissed my way inward. She was already wet and began moaning even before I got to my destination.
Mom placed her hands on my head to speed me along as I neared her drenched pussy. She whimpered when I placed my open mouth on her and began exploring her with my tongue. I licked her in strokes and pentrated her with my tongue in alternately, making her harden her grip on my hair as she started breathing heavily.
I brought her close, but didn't let her cum. Instead I broke free and went back to kissing her thighs, then moved up her stomach to probe her breasts with my mouth. She sighed with disappointment, trying to guide my head back to her crotch. I obeyed, but as her breathing picked up pace again I broke off once more, making her grunt with displeasure at my teasing.
"Please baby... please..." She whispered, begging for it.
I just smiled and kept sucking on her hard nipples until I was satisfied, then finally moved down again to lap at her sensitive pussy. She was reacting to every lick, prod and kiss now, moaning perhaps a little too loudly.
Just as I could tell she was almost about to loose herself in orgasm I sat up, took my ready cock and guided it quickly to her opening. I thrust in hard, making her cry out in an intelligible shout. Luckily the sound was muffled by mom desperately holding both her hands over her mouth. Her eyes were wide and her legs wrapped hard around me, keeping me bottomed out inside her as she came with violent ecstasy.
Her moans slowed down as I continued pounding her, but they didn't stop. She pulled me in for a kiss as I kept thrusting inside her, and when I finally came it was in her embrace. She seemed to enjoy being filled by me and stuck her tongue deeper in my mouth before I collapsed on top of her naked body, panting hard.
Mom slid out from under me after a moment and whispered "Good night" before replacing the sheet on top of me. I remained as she had left me as she exited the room, feeling good but spent. I fell asleep moments later, strange sexy thoughts whirling around in my head which led to even stranger dreams.
My last coherent thought was excitement for tomorrow.
, I woke up earlier than usual. The events of yesterday were fresh in my memory. I jumped out of bed and pulled on some clothes. I felt good; awake and ready to take on the day. As well as my sister.
Just the thinking of the possibilities got my blood pumping. Would I end up fucking both my mother and sister? I paused to wonder if I was a bit twisted for asking myself that question with such enthusiasm. No, I wasn't going to start second guessing myself at this point. Besides, everyone I knew agreed that both my mother and sister were about the hottest things in town. Any man would have jumped on this opportunity. Just maybe not if they were their mother and sister.
My doubts mostly put to rest, yet still nervous, I walked downstairs to find her. Sis stood in the laundry room, putting clothes in the washer.
"Morning Sis!" I greeted, attempting to sound normal.
"Oh. Good morning," she said, her expression even and tone neutral. Not giving me any hints on her feelings on yesterdays adventure. I was impressed.
She wore a pair of fairly tight fitting gray shorts and a white tank top. I watched intently as she loaded up the machine, her petite form bending over in front of me. She didn't seem to care about me being there, so I stood there and gazed at her beautiful long legs and her great ass for quite a while.
God damn, she was hot.
"Hey there John!" Mom greeted. "Find anything interesting in there?" She smiled and winked at me, seeing what I was looking at. Looking like she approved.
"Just hanging out with my sister, Mom," I answered nervously.
"I see. So what are you kids doing today?" she asked.
Sis turned around from the washer. "I don't know. Just hanging around the house I guess."
"I was thinking of hitting the gym today. Been a while," I said, thinking I could get my mind off sex for a while.
"Oh, I'm not sure you need to. You are already sobig," Mom said with a smile. "Don't you agree honey? Just feel his muscles," she encouraged, inappropriately feeling up my chest through my t-shirt.
Sis looked uncertain at first but followed Mom's example, running her hand carefully over my pecks and down my stomach.
"Pretty good right?" Mom asked.
"Yea..." I let her run her hands over me, giving her face a mesmerized look. Then she suddenly snapped back to reality and pulled her hand away.
"Well, if you ladies are done molesting me I think I'll head out," I joked.
"Yea, whatever." Sis snarled, turning her back on me again.
I ate a quick breakfast and then walked back upstairs to pack my sports bag. I didn't have a car yet, because of money and parking concerns, so I walked there. It wasn't very far, and I could count the walking as part of the exercise.
I concentrated on my midriff and shoulders, rounding it out with some sit-ups. I always made sure to work on my back, and stomach, since I sat still for long hours during the day and would likely continue doing the same in my future job.
I tried to focus on the training but it was difficult. I couldn't quite keep my thoughts clear, as thoughts of my mother and sister kept interrupting. I eventually gave up, a little early, and walked back home.
The house was empty when I came back, so I decided to relax on the couch after unpacking my sports bag. I was just about to fall asleep when heard Mom and Sis pulling up to the house.
"Hey there sexy," Mom said when she found me upstairs, her hands holding a few shopping bags.
"Hey Mom," I answered, suppressing a yawn. "You guys went for a drive?"
"Yea," she answered and sat down on the edge of the sofa. "We went shopping."
Her hand stroked my stomach and she leaned in, lowering her voice. "Mommy bought a new pair of underwear, but I think I need a man's opinion on them. You don't mind helping out your poor indecisive mother, do you?" she said, her voice dripping with lust. She moved her hand underneath my shirt to continued fondling me.
"Mom..." I said warningly, watching the stairs. I was as horny as yesterday though, and could feel myself react to her touch.
She withdrew her hand with a disappointed sigh. When she heard my sister's steps from the stairwell. My younger sibling looked as beautiful as always, her blonde hair resting on her shoulders. I sat up in the couch.
"I think you've got some of my stuff, Mom," she informed her.
"Right." Mom stood up from beside me and began looking through the bags, sorting them into hers and my sister's.
"Looks like we won't be making next months rent," I joked, dryly. "Did you guys at least find anything good?" I asked, without really being interested in the answer.
"Just clothes," Sis answered noncommittally.
"Notjust clothes," Mom objected. "I bought that sexy pair of underwear I told you about," she told me. Sis shot her an upset look at that. "And so did your sister."
Mom ruffled through a particular bag and pulled out a pink piece of cloth, which she threw to me. A pair of panties landed on my lap.
"See? Sexy, right?" she said, barely containing her amusement at my sisters reaction.
"What the fuck, Mom?!" Sis shouted and ran toward me, then stopped and carefully leaned down to take the panties away from where they lay in my lap.
Theywere sexy. A small pair with lace borders, just the thought of them wrapped around my sisters nubile nether region damn near made me salivate. She must have noticed how I was staring at them, as my thoughts were interrupted by her, red in the face, gently trying to pull my attention away from them.
"Um... Bro?" she almost whispered. "Can I have those back?"
She hooked her finger around the underwear before I could answer and pulled it away from me, revealing the erection pressing against my jeans underneath. She froze for only a millisecond, her eyes going wide, before she turned around and left for her room. I could have sworn I saw her biting her lip as she left.
"Hey! You forgot your bags!" Mom yelled after her.
When she didn't respond Mom went down on her knees in front of me.
"That was great darling," she whispered.
"Um, what? What do you mean?"
"Don't tell me you've forgotten what we talked about yesterday? Either way, you did your part perfectly," she explained, putting her hands on my knees and pushing her breasts together between her arms in the process.
"Oh." Idid remember of course, but hadn't thought about it right then. "I do remember. Do you really think that turned her on?" I said, thinking back to her reaction. It certainly looked that way.
"Mmm... How could it not?" Mom purred and slid her hand down my leg to where my cock strained against the denim.
I grunted at the sensation and leaned back, my cock suddenly feeling trapped inside my pants.
"Sorry sweetie," Mom said, pulling back. "I know you're as horny as I am, but it won't be long now. We'll settle this tonight. I know it." She stood up and gave me a motherly kiss on my forehead before she left. Leaving me on the couch, suffering from a bad case of blue balls.
After I recovered, the rest of the day went by more or less as usual. We spent time by ourselves, made dinner together, watched some TV in the evening. Soon enough it was time to go to sleep.
**
Once again I lay in my room, waiting. Mom entered my room just a little less carefully than usual. The door creaked as she closed it behind her, yet left a generous gap between it and the frame, should anyone want to peek in.
She pulled off her large t-shirt to reveal her naked body underneath. Again, I was stunned by the sight. She had a body that could rival any 20-year-old girls, though it was much more mature. Mom crawled under the sheets with me, resting her soft breasts against my side.
"Finally..." she purred in my ear. "Are you ready for tonight, my dear son?" she asked.
"Fuck yea," I whispered. I had been waiting all day for this. Whether Sis showed up or not, was happy enough to fuck Mom. Though it had only been a day, it felt like ages since last time.
"First we need to get you warmed up. Remember to look like you're sleeping darling, mommy will do all the work." She smiled, sat up and threw off the bed sheet.
She went right for it, probably as eager as me to get a release. Positioning herself above my crotch, she reached down and guided my cock to her opening. Her cunt was as wet as I was hard.
A pleased squeak escaped her lips as she sat down on my cock. I groaned as my rod was engulfed by her tight pussy. It felt amazing to finally get to bury myself inside of her. Mom held both her hands over her round tits, cupping them and playing with her nipples. She leaned her head back as she moaned, clearly enjoying herself. I was tempted to reach out and grab her, but held back. One more night of pretending to sleep wouldn't kill me.
She rode me like that, hands on her breasts and facing the ceiling. Her moans filled the room as my cock slid in and out of her furthest reaches, drenched in the juices that flowed from her swollen cunt. I watched as she fucked me, keeping a steady pace. I watched her bouncing tits and her euphoric expression as her juices ran down my cock and legs, creating wet spots on the sheets.
"Aaah... Fuck yea. Let mommy fuck you Son," she moaned and tightened the grip of her legs around my waist.
"Who would have ever thought my own son's cock could feel sogood?" She grunted the last word as she lowered herself on me again, plunging my cock deep inside her hole.
I was starting to suspect she was speaking to our audience. The thought of my sister watching us made my dick twitch with anticipation as it rested inside my mother. I kept my eyes on were our bodies connected, loving the sight of my cock slipping in and out of her.
Before long she was getting close to orgasm. I could tell by her ragged breath and the increase of pace. She had leaned back further, reaching one arm behind her to use as support while the other hand rubbed her clit and assured my dick stayed in place inside her pussy.
"Fff- Fuck! Ah! Aaaah!" she yelled and bent forward, putting her head next to mine on the pillow. The muscles of her pussy clamped down on my cock as she came. It only took me a few more hard thrusts to join her, Mom's soft post-orgasm whimpers still in my ear.
After a day of waiting, I was finally filling her with my semen again. I groaned as my seed unloaded inside of her, coating her walls in her son's sticky sperm. I kept thrusting through the orgasm, carelessly grabbing her thighs, and then fell back down on the pillow as I finished.
As soon as I recovered from my orgasm a grin spread on my lips. There really was nothing quite as satisfying as that. A trickle of my cum dripped out as I pulled my shrinking cock from her warm embrace.
"Thank you Son, that feels so nice in me," Mom purred in my ear. Low enough that only I could hear it.
**
She lay on top of me for a while, kissing my neck and then my lips, giving me some time to recover. Mom sat up and carefully scooped up some of the cum, a mixture of hers and mine, that was trying to escape her pussy. She licked it off her fingers sensually, putting on a bit of a show, making sure I saw everything. Then she crawled down to suck the liquids off my cock, making sure I was reasonably clean for what was to follow.
When Mom was satisfied with her work and the state of my once again growing penis she stood up and left, taking her robe with her.
This was it. The moment of truth.
I lay still on my bed, waiting long after I heard the door to my mother's room close, loud enough to be heard anywhere in the house in the silence of the night.
After a while, the door opened again. My sister was wearing the same thing she had last night, a large t-shirt and underwear. She snuck into the room and up to my bed, barely making a sound.
She didn't waste much time, going straight for my cock and closing both her hands around it. I quickly grew to my full size in her cold hands. She leaned in and sucked on the head, not bothering to check that I was asleep this time. It looked like she had been looking forward to this.
It struck me again how cute she was, even showing this sluttier side of herself. She brushed her hair out of the way when it fell in the way of her view of me. Her big eyes watched me for a reaction as she sucked and licked the tip of my penis. I kept my eyelids low, secretly looking back at her in the dim light.
"You like this brother?" she whispered. "You like the feeling of your dirty little slut sister sucking your dick?" She obviously didn't expect me to answer, but I very muchdid like it.
"What would you do if you caught me like this?" she continued, her voice low. "You could punish me any way you wanted..." she said, sounding more and more excited.
"Any way..." she repeated and sat up, reaching her leg over me and positioning herself over my erection.
I watched her push her panties aside and guide my cock to her opening, holding it so that it pressed against her folds. Ever so slowly the resistance of her pussy gave in, allowing my tip to slide just a short bit inside.
"Mmm..." she moaned as my dick began to fill her. She took her time lowering herself on me, which was understandable as I could feel just how tight she was. The walls of her vagina felt like they were barely letting the head of my cock through, hugging the shape of what little had entered her.
Suddenly the lights turned on, startling both me and Sis. Mom stood by the door, watching us.
"So," she said sternly, "what is going on in here?"
Sis shrieked and threw herself off me, landing on the floor with a thud.
"Looked like you were enjoying yourself, young lady," Mom teased.
My sister's face flushed red and she crawled away to sit against the wall, looking bewildered.
"I... um, I wasn't doing anything!" she peeped.
"It sure looked like something," Mom said, grinning.
Her face got even redder and she stuttered, "Bu... but... what about you, huh? I saw you Mom. You were using him..."
"Just like you were, you mean?" Mom retorted.
Sis pulled her legs up against her stomach, looking like she wanted to be anywhere else.
"I... I didn't mean to. It's just..." she mumbled.
"Besides, he's not really sleeping," Mom told her.
I sighed, and sat up in the bed. My sisters eyes went wide and she put her hand over her mouth to stop a terrified squeak. I felt a bit bad for her.
"What the fuck?!" she exclaimed, like she couldn't believe her eyes.
"Hi, Sis," I greeted, feeling sheepish.
"Well, you can't just leave him like that," Mom said. "Don't let me interrupt."
Mom took my sister under the arms and pretty much carried her back to the bed, positioning her over my still aching cock.
"W... What are you doing?" my sister said, her voice panicked.
"I'm letting you finish what you started. Are you saying you don't want to?" Mom asked.
"I... it's not... um... what?" she tried.
"It's okay Sis. I want you to. I wouldn't have lain still if I didn't," I assured.
"R... really?" she stuttered.
Tears were running down her eyes, but it looked like my words had calmed her somewhat. She gave me a brief, unsure smile as I took hold of her hips and guided her down on my cock, Mom supporting her from behind.
She got into again it remarkably fast. Her aversion giving way to lust as my cock found it's way deeper inside her. She was very tight, but also very wet, which helped.
"Were you really, aagh... really awake all along?" she asked, her eyes looking both horny and unsure of what to make of this.
"Yea," I answered. "Even yesterday. That was one of the hottest things I've ever experienced."
She blushed, once again, and let herself fall the rest of the way, making me bottom out inside her. She yelped at the sensation and then suddenly leaned forward, a few tears still running down her cheeks, and kissed me. I returned the kiss and held her tightly.
I slowly began moving inside of her, pulling out and in again carefully. She laid her head beside mine, arched her back and moaned in pace with my thrusts. We lay there for a while, humping with her face hidden in the side of my neck. She felt amazing, her petite body locked in my embrace.
"I love you, Sis," I whispered in her ear.
That seemed to get her even more excited, and her walls clutched me tighter as I spoke. It didn't take long for her to cum, writhing in my arms and whimpering as shivers traveled through her body like electricity.
I joined her not long after, unloading my sperm right into her already cramped cunt. She rolled off me just after I finished, white fluid trickling out from her pussy. Mom laid down beside her, rubbing her shoulders.
"That felt good, didn't it?" she asked my sister.
"Yea..." she got out between breaths, still holding on to me.
"See, I told you she wanted you," Mom told me. "I get the feeling things are going to change around here from now on. No more holding back. We are all going to help each other enjoy ourselves," Mom said.
We all fell asleep together. Naked, content and unabashed, lying next to each other.
**
"Ow, ow, ow..." she muttered, hands to the side of her head, gripping the sheets.
"You okay, Sis?" I asked, stopping my progress.
I had only gotten the head of my cock inside. It was as engorged as it could get at that point though and it strained against the walls of her ass while her muscle clamped down on my shaft, as if trying to strangle it.
"I'm fine," she insisted, not sounding it.
"Look, Sis. It's okay if you can't. You're smaller than Mom. You don't have to do this just because she could," I comforted, brushing strands of her hair that had gotten loose back behind her ear.
"Shut up. That's not why," she bit back, sounding annoyed. "Just do it."
She went back to staring at the sheets, silently waiting for me to obey. Her chest lay on the bed while her knees and feet rested on the floor, giving me easy access to her ass. I could hear her uneven breath slowly settle, unused to the pain of having a cock shoved up her butt.
Fine, I thought.I guess I'll give her what she wants.
I pushed further in. Not quickly, yet I wasn't going slow either. I pushed with an even and unrelenting pace, inch after inch disappearing inside her asshole. The walls of her rectum had no choice but to part and stretch as my cock drove into her like a bulldozer through a shack.
"Aaah! Ghaa! Fuuuck!" she yelled as I impaled her. I stopped.
"I told you it was gonna hurt," I reminded her, still feeling a bit guilty.
She didn't respond immediately. Couldn't. Sis took a moment to recoup, breathing heavily, before she turned her head around. She looked like she was holding back tears.
"Fuck Bro... You feel even bigger inside there," she complained. "This is pretty hot though," she said, smiling despite the pain.
"It is," I agreed. "But... Well, I'm not actually all the way inside you yet," I said, feeling guilty once again. I probably didn't need to tell her that, but I only had an inch or so left and I desperately wanted to fit it all inside. Her satisfied expression instantly melted.
"What the fuck? How much more?"
"Just a little bit. It won't be that bad, promise," I assured her.
"Fine, go ahead," she relented.
I thrust the last part in much more quickly, producing a high pitched yelp from my sister. I pulled back a bit and then thrust in again slower, setting a steady pace. She was clearly a bit uncomfortable, but it didn't take many of my thrusts for her pained moans to change into ones filled with pleasure."Looks like you're already enjoying yourself honey," Mom said seductively, laying naked in front of us, watching. Sis nodded her head but kept her teeth clenched together.
"It does look like a lot of fun," Mom purred, getting up on her knees and pulling her fingers from her wet mound.
She presented her sticky fingers to my sister who, to my surprise, sucked her juices off without hesitation. Mom moaned with appreciation as her daughter licked her fingers clean. She grabbed the back of her head, pulling it up as she positioned herself in front of her on the bed, legs spread.
"Here baby, taste mommy properly," she purred, wild with lust, and shoved her daughters face into her cunt.
My sister apparently responded well to the challenge, as Mom almost instantly cried out with pleasure, throwing her head back. She kept one hand entwined in my sisters hair as she whimpered and moaned at the sensation of her own daughter lapping at her pussy.
It was quite the view. I felt myself quickly approaching orgasm. Pumping my cock into my sisters ass while she ate out my mother proved too much for me to handle. I lasted only seconds more, finishing quicker than I had in years.
I groaned loudly as the ecstasy of orgasm overtook me, squirting jets of hot liquid into my sisters rectum. Sis reacted to the sensation by moaning loudly into the folds of her mother, which intensified Mom's moaning in turn.
Several streams of my cum shot into her before I was done. I slumped over, using her soft ass-cheeks as support while my drained cock still rested inside her.
"Jesus... That was amazing Sis," I got out, in between breaths.
"Any time Bro," she said, panting hard, only taking her mouth off Mom long enough to respond.
As I would find out later, it turned out she meant it.
I fought the instinct to lie down and fall asleep, making sure both of them were thoroughly satisfied before I allowed myself to relax.
**
"Put your tongue out properly and lick it like this," Mom instructed, sliding it from the base of my shaft all the way to the top, not stopping until the tip of her tongue pushed off the head of my cock. A droplet of her saliva fell from my cock onto the wooden floor.
"It's as much about presentation as sensation," she explained, sounding very knowledgeable. "Now you try."
Sis opened her mouth and stuck her tongue out, just like Mom had, and looked at her for approval. Mom gave her an approving nod. She grabbed my penis and held it upward, putting her slick tongue all the way down on my balls. Just as Mom had, she slid upward in one stroke but closed her lips around the head of my dick before she finished, sucking it briefly.
"Sorry," she looked at Mom and apologized.
"Heh, that's fine honey." Mom smiled at her. "Improvisation is good, sexy even. I'm sure he liked that," she added, looking up at me. I nodded enthusiastically.
"Oh, hell yea. You are both doing amazingly if you ask me," I agreed.
They looked wonderful, sitting on their knees in front of me in the living room. Sis in her summer dress and Mom in a revealing top. Mom looked unbelievably hot, teaching my younger sister how to give me a blow job. Sis looked cute rather than sensual, but the contrast of her innocent looks and seeing her look back at me with my cock in her mouth just made it that much hotter.
Mom continued the lesson by letting my sister take the lead, giving her helpful hints along the way.
"Gnnngh! Ghaa..." Sis pulled back, coughing. "I can't... How come you don't gag Mom?" she asked.
"Well... I've, uh, had a lot of practice," Mom said, looking a bit uncomfortable talking about her past sex life, strange as that was considering the circumstances. "You just need to practice, eventually you'll be able to ignore your gag reflex."
"You're so far ahead of me. Maybe if you guys had included me from the start I would have already known how to do it," she accused us.
"Sorry Sis," I said, unable to contain a laughter at the absurdity of the situation. "I'll make sure to make it up to you."
"You better," she said and got back to sucking me.
I finished inside her mouth, for only the second time. This time she didn't spit my cum out though. With the help of Mom's encouragement she grimaced and swallowed loudly a few times, opening her mouth after so we could inspect.
"God damn Sis. That was insanely hot." I said.
"It was pretty hot," Mom agreed. "What did you think honey?"
"It tastes weird... but I guess it's not that bad. I kind of like the idea that it's my brother's cum," my sister admitted.
She looked up at me and returned my loving smile.
**
Both my sister and mother lay naked in bed with me. Their bodies squirmed over me, two pairs of tits rubbing on my chest as we kissed each other passionately. Sis moaned in my mouth as our tongues wrestled and I held her head roughly down against mine. I pulled her off, making her groan in disappointment, and pulled Mom up from were she was kissing my neck. I delved deeply into her mouth while she rubbed her wet pussy along my leg. Sis watched us silently.
We kissed and groped each other for a long time in a lustful mess of saliva and roaming hands. Sis and Mom as eager to please each other as me. I scooted down under them while they made out, reaching my sisters succulent breasts. She moaned and grabbed my head as I took her pink nipple in my mouth and sucked. I made sure to give my mother's tits some attention as well, as they continued their hot display above me.
It should come as no surprise that I was hard as steel during that whole episode, and after they finished their girl-on-woman make out session they turned their attention to my erection.
"Mmm... Son. Such a flattering display you're putting on for your mommy and sister," Mom purred, her hand around my shaft. They both slid down to observe my cock more closely.
"Who should get the honor of riding this magnificent dick?" Mom asked, biting her lip.
She looked to my sister, who was also watching my erect cock with lustful eyes, rubbing her vagina in anticipation. For a moment they seemed unable to decide, but then Mom pulled my sister's head close and whispered something in her ear. Some sort of suggestion, by the sound of it. My sister's eyes went wide, and then a smile spread on her face and she nodded.
"I figure you haven't had a chance to try it yet. He's pretty good at it," Mom assured her.
"God, I bet he is..." Sis said and looked up at me, looking eager to try whatever it was that Mom had suggested.
Sis moved back up to my face and let my tongue explore her mouth again while Mom mounted me below. I groaned into my sister's mouth as she pushed my engorged head inside her wet folds, letting my pulsing cock enter the warm embrace of her moist hole once again. Sis pulled away from me, giving me a chance to see Mom gazing at me with a loving expression while my cock disappeared inside her pussy.
Sis sat up on her knees in bed, then put one of her knees on the other side of my face, giving me a clear view of her dripping pussy. I knew now what she was going to do, and I looked forward to it. I reached around, putting my hands on her firm ass, and pushed her forward before she could move. I leaned my head forward slightly, making sure her womanhood landed firmly on my mouth.
"Eeek!" she screeched as my tongue slid over her, tasting her juices.
She tasted good, very similar to Mom and yet different. I lapped at her happily to the sounds of her cute, high pitched, sounds of pleasure. Mom reached around, grabbing her breasts and nibbling at her neck as she fucked me behind my sisters back.
Mom moved her hands to my sister's shoulders and turned her around. Sis pushed off me for a moment as she reversed on me, so that she was facing Mom. I couldn't see, but from what I heard I assumed they had resumed their kissing, and more, from before. She put her sweet pussy back on my waiting mouth with the help of my guiding hands. This gave me even better access to it and I used the opportunity to thrust my tongue as deep as I could inside her.
"Fuuuck... God, please don't stop Bro," she begged, panting hard, from above me. Her thighs tightened around my head. "Jesus, this feels so fucking good Mom..." she continued.
"Mmm... It really does," I heard my mother purr. "Cum inside me Son. I've been getting a bit jealous at all the sperm you've unloaded into your sister. Mommy needs some inside her too," she spoke, her voice brimming with lust.
There was no doubt that I would fulfill that request. I continued eating out my sister while Mom fucked herself with increasing ferocity on my hard cock. It was one of the hottest moments of my life, on a day with many other hot moments, and I enjoyed every second of it. I did my best to ensure my mother and sister enjoyed themselves as well.
"Ghhaaa! Oh Fuuck!" my sister shrieked as she came, her pussy firmly pressed against my mouth. She came over my mouth, what liquid I didn't swallow running down my shin, cheeks and throat. She shivered and pressed her legs hard against the sides of my head.
Mom moaned and pulled my sister's head down in front of her, likely having her suck on her tits. She came not long after, groaning and convulsing much like my sister had, with my cock still thrusting inside her.
I stopped trying to hold back after they had both reached orgasm and thrust more quickly, while still not letting up on my licking of my sisters warm pussy.
I came hard, pushing up as far as I could when I felt it coming. Strong jets of my semen flooded into my mother, filling her like she had asked me to.
"That's it baby, cum inside mommy," she whispered, still weak from her orgasm, while my cock emptied inside her cunt.
We were all exhausted. Sis climbed off me and cuddled up to me in bed as Mom did the same. We were all still breathing heavily as we lay there, warm under the sheets and with our bodies pressed up against each other.
"That was so much fun," my little sister said, grinning at me and Mom.
"It really was, little Sis," I responded. "You tasted very nice," I added, to her embarrassment.
"I love you, Bro," she said, giving me a peck on the cheek. "You too Mom." She smiled.
"I'm glad to hear that honey," Mom said. "I just want you two to be happy. Whatever that means," she told us, suddenly sounding vulnerable.
"Don't worry Mom," I said, kissing her on the lips. "I don't think we are going to get tired of you any time soon." I smiled at her.
"Agreed," Sis said, smiling as well. She leaned forward and kissed her mother in a way that implied more than just familial ties.
It had been a long day and we once again fell asleep together, naked and tired. It was only Monday, a day after we had surprised sister in my room. I wondered how Tuesday would look.
Summer vacation was coming up, and I was now certain of how I was planning to spend it. It wouldn't last forever, we all realized, but we were going to make the absolute most of the following months or years.
It was the best time of my life.
