We were used to "doing our thing" whenever and wherever we wanted. I wondered about the girls. We have one guest room, but they said they didn't mind ...sharing. "If you don't mind a little noise from us sometimes." Yeah Chrissy was very straightforward. So it was settled. The girls brought some clothes to hang out in. Chrissy brought a bag of 'toys'. "A girl has needs". Mel asked if she could share, "As long as it doesn't have spikes or something." This was going to be interesting. We settled. I turned back around and swam a little towards the shore. My eyes hadn’t adjusted properly to the dark yet and everything around seemed to blend together. Getting closer I began to make out that something was on the platform. “Amy, is that you?” It was in fact, someone. Finch's voice was unmistakable. He asked with a sense of bewilderment. I stopped in my tracks and my heart raced to the pit of my stomach. I tread the water around me yet again and thought for a minute about how I was about to. A DJ had set up his gear and presto - somewhere to dance. And dance people did. I spent almost the entire evening dancing. I danced with Fran most of the time obviously, but also had a swing with a number of the other girls. Jake on the other hand spent the entire evening with Denise in his arms. He is admittedly a very good dancer, but he was glued to Denise in a close embrace during the slow dances.Poor Lorraine did her best to attract Jake's attention and in a doomed attempt at making him. She was moaning now and no longer resisting as I undid the robe completely and toyed with her tits with one hand as the other went for her pussy. Oh fuck, she had a lovely bit of pussy fluff that I stroked and played with gradually getting lower until she eventually opened her legs a bit.Now I knew we were going to fuck but I didn’t want to take the chance of letting her go and think about it so I eased up the robe until her naked arse was on show and then released my throbbing cock. She.
