I don't know if it was the tequila or the fact that I was so horny for her, but as I watched her standing there in that tight little dress leaning ove... the sink, I decided to make my move. I moved in behind her and slid my hand around her hips and pulled her close. I could feel her relax and I leaned in kissed her neck. She started rubbing her ass against my crotch and she kind of giggled and asked me what I was doing. I slid my hands up to her tits and started rubbing them through her. The next thing I know we both landed on our asses and slid right into the water together. We ended up sitting in the water right next to each other. The water was up to the bottom of my chest and to the top of hers. “SHIT!!!!” Stephanie yelled. We looked at each other and busted out laughing. I stood up and reached my hand out to her. She took my hand and started to stand up. Suddenly, she slipped again and fell right back in taking me right along with her. This time, I ended up right on top of. The chicken and chips in the basket was as good as it had been the last time; the hotel bar and lounge just as crowded for a Saturday lunchtime. The hotel owner was obviously onto a good thing, and knew it!Once again, as we strolled back to the flat, I relished the feeling of being part of a group of good friends doing something together at the weekend. It just felt so much better than going out with Julie, or with our flatmates; perhaps it was the presence of my sister and her boyfriend that. Amy was doing the same with her date. Fortunately the movie house was not full and we had the back row to ourselves.I made the guy cum and Amy did the same for her date. Then she suggested that we blow this place and find someplace where we could be alone. Amy's date drove us to the lake. There were blankets in the back of the car that we took into the woods surrounding the lake. The sex began immediately. I took my tank top off and pulled my panties down as fast as my date could get his shorts.
