I kept at it, watching as my little sister writhed in ecstasy and She seemed to back into my rubbing hand."This - Feels - amazing."Then, my sister kin... of wriggled higher onto all fours, then she suddenly sat up, on her knees. She said, "Oh God - Oh Michael."And I stopped rubbing her wet vagina.Emmy moved a little, as she sat there in front of me on all fours. She moved the big pillow off my lap, and it fell to the floor. Then she carefully crawled over me slow and catlike, and went all the way. I continued to rub her body and those soft tits and play with those sweet, dark, rock hard nipples as she continued stroking my cock.

Oh, okay. Well, she probably forgot all about it," I said looking up at the cloudless sky. It would appear if she did show up I wouldn't have the weather to use as an excuse to back out of it."She called to confirm, Daniel. She will be here in approximately fifteen minutes." Shit!. The bra was a little too small so her tits were almost coming out of it, and the thong left little to the imagination as her ass was completely unobstructed. It had been months since I’d been inside of Stacie. I was dying to fuck her again. Seeing her with Derrick made my lust for her even greater as I was jealous of watching him get to fill her incredibly tight hole. I stripped naked and climbed on my sister’s bed. I checked to see if she was completely out. I snapped my fingers near her ear,.
