Her ass is what you would call a bubble butt. Tina just turned 21. If you are wondering about me and not just these two ravishing beauties who are b...sy eating each other out, I'm Jim. I'm 27 and I'm 5'11" and weigh 165 pounds. I've got a pretty nice tan and light brown hair that I keep pretty short. I have an 8" rock hard cock with a strong upward curve and I keep my pubic hair and chest shaved. Joan and I have been happily married for three years and swinging for a year. As I stood in. I went red and covered it up but my sister said “were you thinking about the time me and you did that?”. I thought she had forgotten about it so I just said, embarrassed “erm, yeah”. She was laughing and didn't seem to be ashamed of what we did, and because this was the first time in more than two years that either of us had mentioned it, I knew I needed to take my chance.“I can't stop thinking about it, I really, really, really want to try it again”. She laughed and said no way but she wasn't. Thanks Stan, but thats okay. I want to show him some of my pictures and stuff in my room anyway. Oh, for sure. Well, Ill be upstairs. Nice seeing you Derek. Yeah, same, man. About an hour had passed and I was going insane. I couldnt distract myself with a movie or the internet or anything. All I could think about was Derek taking my sisters clothes off. Fuck, I wanted to be doing that instead of him I decided to go near her room. I was little surprised when i saw that she left the door little. I was just standing there admiring the view. Then, from out of nowhere, I heard, "Do you like it like that, whore? Maybe I should take it out and put it in your ass, for disobeying me!" I was shocked by this outburst and very curious. I thought it was probably someone watching an adult movie or something more scandalous. Nothing prepared me for what I found. I turned and looked for the source of the sound, as another outburst echoed to me. "Does it hurt in your ass, whore? Maybe a good whipping.
