Dan came up coughing and said do it again. Bill went over and pulled him up ,tossing him again. I was laughing, and Bill reached back and caught my ar....He said think that's funny and threw me by Dan. We looked at each other and went after Bill, splashing and trying to pull him down. We wrestled around for a while, and Bill said he needed a break. He pulled us close and held us up. I didn't think about Bill's hand on my bare butt,and held on to his neck. I noticed Dan was laughing and kicking. I drifted between the two islands. It was lovely and quiet and hardly anyone else about. Most people on our trip and the boat anchored up nearby appeared to be dozing on their boats and I felt like I had the place to myself.I slowly moved myself backwards using just my hands, when suddenly I bumped into something. I turned quickly, shocked, fortunately the water was only chest deep or I might of got a mouthful. "Ciao," a voice said. I looked round and was confronted by what I can only describe. Iwas so hot from watching her as I stumbled around trying to learn towalk again. There was no way I could get hard trussed the way I was.Dammit!She finally had me sit and started on my make up. When I was done I hadwaterproof mascara (she said she didn't want it to run later), Blue eyeshadow and dark liner extending well past my eyes. My lips matched mynails and she said the lipstick was good for 24 hours.I looked in the mirror and saw a total slut looking back. The typicaltelevision biker. I reached for my zipper, and began to zip up my pants, with the reassurance that if it was my sister, the door would be locked. I was wrong. I had forgotten to lock the door, and she was now looking in, with her mouth open, at me watching some porn star pound a very young teen. With one hand on my now throbbing dick, I managed to stick it back in my pants, and sheepishly turned to look at her. Well I can see your home early, I managed to squeak out. You forgot to lock the door, idiot, She.
