Matt brought his boom box out of the garage and added some oldies (50's 60's rock and roll) music to the mix. As I walked up and kissed Jen, I told that her brother really liked her suit. She blushed bright red saying the other girls harassed she and Betty without mercy until they bought them at a swim shop. I said she really looked good and told Betty she did too. Jen said she couldn't believe Betty went along with it. I looked right at Betty and said I was sure she had worn less when swimming before. Betty hit Tim with a sharp elbow, blushed as bright as Jen had, and said, "I can't believe you told Dan."
Jen laughed and told Betty not to worry everyone goes skinning dipping at least once in their lives. Now I laughed and told Jen, yes they do and you and Betty have more in common than your swimsuits. Now Betty and Jen were looking at each other trying to figure it out. Jen is a brunette with brown eyes. Betty is a redhead with green eyes. Their bodies while well proportioned are quite different. Finally I said, "At least that's what Bryan and Debra say."
Jen exclaimed, "You mean you've swapped with them, too?"
I tried to stop her but it was too late. She had misunderstood. I said, "I meant, skinny dipping with them. Now that cat's out of the bag."
Tim and Betty both stood with mouths hanging open looking dumbfounded. It was Betty who broke the awkward silence. "You know, I thought that was what they had in mind with Tim and I when they got us drunk and we went skinny dipping with them. Especially the way that Bryan kept watching me." she added.
Now Tim spoke up, "What about the way you were looking at his dick?" I looked at Tim, but he didn't seem angry.
Betty asked, "Well, what are you supposed to do when it's on display?" and added, "Women can be curious too and besides you were enjoying the view of Debra as I recall."
"Yes, I was." answered Tim, "But just how curious are you?"
Jen and I were mere observers at this point. As Betty admitted that she was more than curious, she was willing to try it if Tim didn't mind. Tim took one look around at all the women there and said he would too. Betty just walked over to Bryan who was dancing with Jane near the pool. Without a word she just reached out, bent down, and pulled Bryan's Speedo down to his ankles.
Pandemonium struck. All at once their were swimsuits disappearing everywhere. As I dropped mine and turned to Jen, I realized she and Tim were standing next to each other, the only people left with bathing suits. Slowly all eyes turned to them and it got very quiet except for the music. Smiling, Tim turned to Jen, shrugged his shoulders, and said, "Well, I guess it's time for a new puppet show. I've always thought it should have been a brother sister act." With that he whipped down his trunks revealing a cock at least ten inches long and only half way to erect.
Jen shrugged her shoulders and slowly removed her new thong bikini. When they stood face to face as naked as when they were new and exchanged a sibling kiss, the party resumed. The drinks flowed, the music played, people danced and swam. Eight couples, all friends, partied naked and enjoyed the freedom. I was having a great time dirtying dancing rubbing my cock across Debra's ass, when I looked up and saw Jen sitting by herself. She looked upset. I walked over and sat down next to her. I asked her if she wanted to leave. She said, "No, you're having a good time, we don't have to leave."
I said, "Remember our deal? If "we" don't have a good time then "we" don't have a good time."
"Dan, I just feel strange around Tim." Jen said.
"I know, Jen. But think about it. Jane and Suzanne. Nina and Jill."
"Yes, but this is different, this is brother and sister. We could really have intercourse. We could really fuck one another." she was almost crying.
I cleared my throat and said, "Listen, I've never said anything to anyone, but" and I paused "when I was young I had a sister one year older and one a year younger. We didn't screw one another but we played doctor. You show me yours I'll show you mine. There was a little touchy-feely and that was all, but if we had been older........who knows? The thing is, you don't think bad of Nina or Jane or Suzanne or I hope, me. It is a natural, normal feeling to love your brother, if you don't want to be with him that's fine, but if you do don't assume everyone here is going to think bad of you. Look around, has anyone got anything to say about how someone else chooses to live?"
