My eyes followed the line of her spine under her tight tank top down to the curve of her hips. The gray workout shorts she was wearing clung nicely to... her firm round ass, moving up around the curve of her cheeks.I could not help but think about how she came last week while I fingered her ass as we fucked in my pool. She said she wanted to get used to things in her ass to get her ready for me to fuck her back there. So far we have only used fingers and a small silver vibrator I gave her, but. In doing so a breast popped out of her bra. By now I was horny as hell and I wanted to suck on her nipple. Her hands slid down to my ass and unconsciously she hugged my buttocks tightly. She pressed her cheek to my belly like a pillow and moaned softly. Laying flat on her back it was easy to pull her skirt down her legs. She was an inviting scene with her breasts exposed, bra hanging loosely, her panty wedged up between her legs. I could see her labia plainly exposed. I stood next to the bed. Before we left I picked up the remote and my camera and put them in a bag to take with us."What's in the bag Uncle?" Cassie asked."I brought the security remote so that we can stay up there for a bit" I said. Turning to Sandy I said "There's a security system that alerts me if anyone comes up the road. There's a fixed one in the cabin - we knew when you opened the gate and we could see it was you on the monitor. There's also a remote that I can bring with me when I'm out of the cabin. It helps. “Cheeky” she says slapping my bum, “I knew all the time I wasn't wearing any knickers”.“Ha ha, I wasn't quite sure... you’re a good actress”.“Of course I knew, I’d just been to the toilet for a wank remember? I got a canny kick out of it mind...did you see the look on them lads faces?” “I did, I even got a pic of them... funny as fuck”.“Fancy you telling them I was your daughter”.“Ha ha, I don’t think they believed me and if they did it’ll give them something to talk about for the next few.
