"Promise me you will not get upset with what I tell you."
"I respect your opinion and will not get mad at you."
"OK, go put this mystery bikini on and come back in so I can tell you what I think."
Sally left the room to go put her bikini on. I sat there on my bed and started to get a little stiff. Thinking about what she said about the bikini maybe showing too much skin, I was hoping for it.
Sally came back into my bedroom in a bathrobe. She stepped into the room and closed the door.
"I want your honest opinion Dan."
With that, she untied the robe and let it slip off of her shoulders and fall to the ground.
What I saw left me speechless for a couple of seconds. Sally had on what you would call a micro bikini. There was only enough fabric on the top to just cover her nipples and areola. The bottoms had a small strip about 3/4 inch wide that barely covered her lips.
"Damn, that is one sexy bikini, if that is what you would call it."
Sally had this funny look on her face and started to bend down to put her robe back on.
I do not know where it came from, but I said, "Stop, stand back up and let me look at the sexiest thing I have ever seen."
Sally stopped and looked confused. She looked up at me. "What did you say?"
"I said stop. Do not put your robe back on because I want to look at the sexiest thing I have ever seen. That is what I said."
Sally smiled and stood up. "What more do you want to see?"
"Turn around so I can see the back."
She turned around and there was her glorious ass. There was a small string around her waist connected to a string that disappeared in the crack of her ass.
"Just as I thought, you have one of the finest asses I have ever seen. I don't think you should wear that to the beach."
"Why not?"
"Because I want to be the only one that sees you in that bikini. It is also because if you wore that to the beach you would be followed around by all the horndogs at the beach."
"You would also probably get arrested for indecent exposure. I do not think your exposure is indecent but that is just a stranger speaking."
"If I was not your sister and you saw me at the beach wearing this bikini, what would you be thinking?"
"I would be thinking how nice it would be to have you on my arm while we were walking the beach, knowing that every man and even some women would be envious of me being with such a beautiful woman."
"I would also be thinking how nice it would be to slowly take that bikini off of you and then give you pleasure with my tongue and then fuck you. That is what I was thinking."
"You really feel that way?"
"Yes, I do. Do you have any other bikinis to show me?"
"This is the only new one I bought. I know how I look in the other ones."
"So, you are going to make it a mystery for me until tomorrow?"
She walked over to me and leaned down and gave me a kiss on the lips.
"Thank you for the compliment and your opinion. I will take your advice, and only wear this bikini for your viewing pleasure."
She then turned around and bent over to pick up her robe, shaking her ass at me as she did. She put her robe on and went to the door. She turned around as she reached for the doorknob.
"See you in the morning, big boy. I think there is something that you need to take care of this evening."
She laughed a little, opened the door and left. She left the door open when she walked away and laughed some more.
I called her a bitch and sprang from my bed and closed the door. I swore I would get her back.
I laid back down on my bed and jacked a load out thinking of all the things I would like to do to my sister. I cleaned up with some tissues and went to sleep.
I woke up the next morning alone again. I was really missing my morning wake up blowjob. Only one more morning without one though. Sally will be leaving Sunday afternoon to go back to school.
She only had 4 more weeks of school then she said she will be home for the summer.
I got my things together for the beach and put on my trunks and a t-shirt with sandals.
I went down to the basement and got the cooler and filled it with water and soda. I got the ice out of the basement freezer, and I saw a couple of those margaritas in a pouch, so I put them in there for the girls.
I was waiting in the living room for Sally to appear. She strolled down the stairs.
"I swear, you will be late to your own funeral. Do you not know how to tell time?"
Sally looked at me and stuck her tongue out.
"Do not stick out your tongue unless you are willing to use it."
Sally looked at me and gave me the finger.
"Come on, let's get going and pick up Ursula."
We loaded the car and I drove over to pick up Ursula. I forgot to tell her that Sally was going with us but when she saw her, she screamed and opened the door and gave her a big hug.
"We are going to have so much fun teasing the boys today, Sally. I am mad at you for not telling me Sally was going to be with us today."
"If you had we could have coordinated our swimwear."
Ursula got into the back seat and off we went to the beach. When we arrived, there were no close parking spaces, so I left the girls with our gear and went to find a parking space.
I had to park about 8 blocks away. I finally arrived at the beach and realized it was packed and did not know where the girls were. I scanned the beach, and they were looking my way waving at me.
I walked down the beach to where they were and helped set things up. We put down a beach blanket and then 3 towels on top of it. We used the cooler and some sand sharks to hold the beach blanket down so it would not blow away.
I took off my t-shirt and sandals and sat down on my towel.
Sally and Ursula looked at each other and proceeded to take off their shirts. Four bikini clad breasts greeted me. I was able to get a look at then while their shirts covered their faces.
I knew it was going to be a hard day at that point. Both girls had on bikinis that barely covered their breasts. I watched them unsnap their shorts and slowly wiggle then down their legs and over their feet.
Ursula had on boy short bottoms because of her hefty ass. Sally had on traditional bikini bottoms that showed off her assets but not any skin of her ass.
Both of them were beautiful and I noticed a few guys staring at them while they uncovered their bikinis.
They sat down and started to apply their suntan lotion. When they were finished with their fronts, legs and arms. Sally asked me if I would put lotion on their backs.
They laid down on their towel next to each other and Sally held out the suntan lotion.
I kneeled on the beach blanket between these two beauties. I was going to enjoy this. I had put suntan lotion on both of them before but not with them together. I was going to take it slow and cover every inch they had exposed.
I opened the lotion and put a dab in my hand and rubbed my hands together to warm it up. I leaned down and started rubbing the lotion into Sally's shoulders. I added more lotion and started down her back.
Sally reached back and untied the string of her bikini and laid them at her sides. I could see her side boob and started to get hard thinking about sucking her tits.
I rubbed lotion down her back to the swell of her ass and back up. I added more lotion and ran my hands down her back again and then up her sides barely grazing her side boob.
Sally did not say anything or move at all, so I added more lotion to my hands and ran my hands up both of her sides again covering her side boobs with lotion. Sally moaned and did not say a word.
Ursula did not see what I did because she had her head turned looking down the beach. Sally rose up a little and looked at me and smiled. I could see her tits and her nipples.
"Thanks, you really know how to cover every spot. I hope you are willing to do that again later after we swim. You know you can never have enough lotion on when you are in the sun."
She then reached back and tied the string. I turned and started to put lotion on Ursula. She was not as passive as Sally and reached back and untied the strings at her neck and back.
Ursula laid there with her full back exposed. She had larger breasts than Sally so there was a lot more side boob exposed.
When I looked up, Sally was watching me. I lathered up Ursula's back and did the little side boob trick on her also. She raised up a little on one of my slides up her sides and I was able to pinch her nipples.
Sally looked at me and smiled. Then she sat up and cupped her boobs and stuck out her tongue at me. I was hard as a rock by this time.
Sally looked down at my hard cock in my trunks and licked her lips. Because of our interaction growing up I did not know if this was her usual teasing or a signal for something else.
I finished with Ursula, and she said, "You can do that for me anytime you like. I love the feel of your hands on my skin."
"It does feel nice, now that you mention it. Dan would you be willing to do that for your sister also?"
"If it pleases both of you, yes I would be willing to do it again."
The girls got up and said, "let's go swimming", and ran to the water. I had to wait a couple of minutes to allow my cock to go down a bit and joined them.
We floated and looked for shells until the girls decided that while I was reaching down to pick up a shell, they would dunk me. I slipped away from them and threatened them that I would get them back.
I went after them, and we horsed around trying to dunk each other. At one point I had my arms around Ursula with my hands firmly grasping her ass under water when Sally came up behind me and put her arms around me to try to pull me away from Ursula.
As we moved around her hands slid down and one of her hands slid over my hard cock. I started to say something when Sally grabbed my cock and squeezed it.
She leaned into me and whispered in my ear. "My, my, you are a big boy like mom said." With that statement she pulled away from me.
I was stunned and let go of Ursula. "I am going back up to the beach to get some more sun. Anyone what to join me?'
I told Sally that I was going to stay in the water a little longer and Ursula said she was going to join me.
Sally turned and walked back to our spot on the beach. When she was out of hearing range, Ursula said, "You sure were handsy there when you were putting that suntan lotion on me and when we were goofing around just now."
I started to say something when she put her finger to my lips and leaned in to whisper to me. "No need to apologize, I liked it and cannot wait for you to get me alone so you can do anything to me you want."
"I wish we were alone right now because I want to lick and suck your tits, ass and delicious pussy."
"Down tiger, you will get your chance after we put on a show for Lucy."
"Now that we are alone, we need to set the ground rules for you fucking me in the ass."
"I was thinking that we would do it similar to the way you fucked me in the ass. I would order you to get naked and get on your hands and knees, then I would fuck you in the ass and tell you that you could leave."
"I will make sure you are lubed up and I will take it slow with you. We will have to think of a signal for when you want to me increase the speed of my fucking.'
"You have to use a toy that is no longer than six inches. Do you have one that small? I know how you like big things."
Sally slapped me on the shoulder. "I have just the right size for you. It is just about six inches long and is about one inch in diameter."
"I do not want to ruin you on the first go around because maybe if you like it I could do it again."
"I am not promising you anything at this point. We will just have to wait and see how my ass feels after you fuck it."
"How do you propose to keep your cousin from finding out it is me?"
"Well, I have bought you a face mask that only shows your eyes and mouth. That way it covers your facial features and hair. You will also be wearing a cock cage."
"We have to convince Lucy that you are really my slave. I will not ask you to wear a collar though."
"You seem to have this all planned out. When were you thinking about winning your bet?"
"I know you have school on Monday, Wednesday and Friday. Why don't you come over on Tuesday and we will do a test run? I will let you fuck me in the ass and then I will fuck you in the ass. This way we can see how you feel on Wednesday and be ready for Thursday."
"What time do you want me over on Tuesday? I am starting my first day as your mom's intern. I will be available after 12 noon."
"Why don't you come over right after you leave mom's office. I will have everything ready for you."
"Let's get up there with your sister before she suspects something."
We exited the water and went to our towels.
Sally just handed me the suntan lotion and untied the string around her back.
I lathered up her back and brushed against her side boob again and she did not say or do anything.
I also lathered up Ursula in the same manner. I then laid down on my stomach and felt four hands on my back. I looked over my shoulder and both Ursula and Sally were rubbing suntan lotion on me.
"We could not expect you to put lotion on our backs without doing the same for you." Sally said. I just laid there and enjoyed myself.
It got to around 2:30 pm when Ursula said she wanted to go home, and Sally agreed with her. We packed up our gear and walked to the parking lot.
I ran to get the car and drove back and picked them up. They both got into the backseat together for the ride home. All through the drive they were whispering together. I wonder what they were talking about.
I dropped Ursula off and drove home. We unpacked our gear and went into the house.
"Thank you for a wonderful day, Dan. We will have to do more of that this summer." She then leaned in and gave me a kiss on the lips.
I had this stunned look on my face. She smiled and went to her room. When she got to her door. she turned to look at me. "See you at 6 pm tonight, big boy for our dinner and dancing date." She went into her room and closed the door.
I went to my room and got my clothes and went to take a shower.
I was wondering where mom was because we did not see her. I turned on the water and waited for it to get warm. I got under the water and started to soap up my body when the door opened and then closed.
"I am in the shower Sally. Please leave. I will let you know when I am done."
The shower curtain slid over and to my surprise there stood mom and not Sally. Mom put her finger to her lips to show me to keep quiet.
Mom went to her knees and engulfed my cock. As she was blowing me my cock raised to the occasion. Mom took me into her mouth until she started to gag and then moved her mouth up and down my cock stopping just before she started to gag.
I could not hold back long because of my constant state of arousal during the day and blasted a full load into mom's mouth. She swallowed everything I offered her. When she was sure that she had gotten all of my spunk she lifter her head, looked at me and smiled.
"Have I ever told you how much I enjoy sucking your cock and swallowing your load?"
"Yes, you have. Every time you suck my cock and I like to hear you say it."
Mom stood up and gave my flaccid cock a squeeze. "Tomorrow night this cock fucks me in the mouth, pussy and ass. Do you hear me sir, my son."
"I am looking forward to it my, mommy slut. Now get out of here before Sally catches us."
Mom smiled, "that could be interesting and fun", and she left the bathroom.
Thoughts of mom and Sally in a sapphic embrace filled my head.
I finished my shower and wrapped a towel around me and started to my room. When I got to Sally's door, I let her know I was finished and went into my room, closed the door and got dressed.
I was downstairs at 5:45 waiting for Sally. I just knew she was going to be late because she always is. When I heard heels on the floor. I looked at my watch and saw it was 5:55pm. Sally was early, will miracles never cease.
She came down the steps and my jaw dropped. She had on a black mini dress that came down about 3 inched past her ass cheeks. Her hair was up and she had on 5-inch heels. She had a bag in her hand.
"Well, what do you think?"
"I think I have died and gone to heaven. I will be out with the hottest woman in town tonight."
"Thank you for the compliment. Now, take me out to dinner I am starving and then we will dance the night away."
I put my arm out and Sally laced her arm through mine. I led her out to my car and held the door open for her. When she got into the seat, she flashed me a glimpse of her red panties. She smiled at me and buckled up.
If I did not know any better, I think my sister was trying to seduce me. How I was wishing she was as I would not turn down the chance to sample her wares.
I took her to a nice steak house, and we had a wonderful dinner. She did not flirt with me or make any sexual comments during dinner.
After I paid the bill, and we were walking to the car Sally looked at me. "Thank you for a wonderful dinner, where are you taking me dancing, big boy."
There was that "big boy" reference again. "I thought we would go to Satchel's." Satchel's is a dance bar with a gigantic dance floor. I have been there a couple of times but never with a woman.
"How exciting, I have never been there but have heard things about it. Are you ready to dance our asses off?"
"If you danced your ass off, what would I have to look at then?"
"Flattery may get you somewhere, but we do not know where."
We got to the car, and I held the door open for her again. This time she kept her legs closed when she got in, so no peep show.
I walked around to my door and got in. I drove about 15 minutes and arrived at Satchel's. There was a line about a block long. A friend of mine was the door man and when he saw me, he said, "VIP's always get preferential entrance to the club", and ushered us in.
We heard some grumbling, but he shut them up quickly.
"I did not know he worked here but now I am glad he does. I really did not want to wait in that line. What do you think of the place?"
The inside of Satchel's was bare brick walls with no ceiling. The beams for the roof exposed and painted black. There was a large dance floor surrounded by high top tables. There was a long wooden bar on the right and the stage on the left of the dance floor.
We went up to the bar and I ordered a round of drinks. The bartender just looked at me and nodded, knowing I was not of legal age to drink. I paid the bill and left a generous tip.
I rejoined Sally and we found a table in the back. We sipped our drinks and chatted.
Sally again thanked me for taking her out dancing.
"It is my pleasure to be able to take a beautiful woman out to dance. Just look at all the men and some women who are envious of me. I have the sexiest woman in the place with me tonight"
Sally looked at me and leaned in and kissed me square on the lips. This was not a sisterly kiss either. She held the kiss for about 10 seconds then leaned back and took a drink.
"What was that for?"
"To show all of those hound dogs out there that I am with you tonight and not to bother me. You ready to dance?"
We went out to the dance floor and started to dance. After dancing three songs, we went back to the table and finished our drinks.
I went to the bar to get us two more and when I started back, I noticed that there were two guys standing at the table talking to Sally.
As I neared the table, I heard one of them say, "We saw that guy you are with and believe we can give you what he cannot. You just need to leave with us and we will rock your world."
"I am sorry, but my boyfriend will be back soon. I have not seen him in a while and am not interested in leaving him here to leave with the two of you."
