With my wife only feet away snoring from an afternoon of drinking wine, I fucked her younger sister on the same corner sofa unit. It was strange sliding my cock into her sister, who had also been drinking. She's no model or anything, but she's a real life dirty bitch and had me fucking her arsehole just before I shot my load deep inside of her. Thinking that was it, she practically dragged me around and forced me to lay on the carpet with my head resting on the sofa. Straddling my head, she lowered herself and made me lick and tongue her pussy and arsehole. It was only a few minutes, but in that time she came at least twice and forced me to lick my own cum from her rear hole. I'm not saying I'm any sex addict or the world best lover, but my sister in law now calls by as much as she can for me to fuck her. And what's even more strange, is I'm pretty sure my wife knows and accepts her sister is now enjoying my cock too.
