M25 F21 During a game of horseshoes I was at opposite ends from my sister. She's cute as hell, thick, huge titties(I'd guess E cup or better) nice jiggly ass and hairy pussy which she don't mind if a little hangs out the side of her white low cut, a couple sizes too small, bikini. Anyway while we were playing, I had so many shots of her bending over, ass shots, and great cleavage shots. I made it quite obvious that I was stealing glances and I think she was bending over like that on purpose, you know, not bending at the knee, so I got a nice ass shot and taking a little longer picking up her horseshoes. Let me get to the good stuff..we're sweaty, my swimming shorts are starting to bulge, we are drinking a bit too much, and go swimming. More heightened excitement for me. Seeing her dark pubes and water glistening titties with dark areolas peeking through her top made me want to take her then and there. Fast forward to later. My girlfriend had worked earlier, came home and drank a few with us. She's a lightweight so it was only 2 glasses of wine for her and she was tapping out. She went upstairs to sleep and me and sis stayed in the living room watching a movie. One which contained a nice deal of sexual encounters. We were each under a blanket foot to foot on the sectional. Our feet were rubbing and one thing lead to another. She started getting closer to my throbbing cock. Next thing I know she's pulling up her nightshirt and exposing her massive rack while sucking on my hard cock. She had the warmest mouth thts I'll never forget. Before o exploded in her mouth, I took the initiative to work her shorts down and take her wet pussy doggy style. At one point she let out a loud moan. I was so afraid of my gf hearing it, but that made me hornier. I pulled out and had her take it in her mouth she didn't hesitate to, then seductively spit some onto her titties and rubbed them. It was some of the best sex id ever had!
