It didn't look right to me and I told Sherry so--Sheila was still struggling and saying something. Sherry said I should massage Sheila's cunt, and onl... take her ass after she got excited. She said if Sheila started getting excited and wiggling her ass in an inviting way, I would know she wanted it.Well, I told her I wouldn't do it unless it was obvious Sheila wanted it. But I started caressing Sheila's cunt with my fingers. Sherry told me to make sure they were wet and to make sure I fingered. I see that he is hard through hos pants already. He plays a video on hos computer. It's a video of him with Tracy. My sweet Tracy on her knees like a slut sucking his hard cock. He demands I take his cock out.

One day, I was in watching TV and she walked through the room, stopped suddenly, faced me and pulled up her teeshirt flashing her breasts, her perfect breasts, at me, then went right on out and up to her room.I went to my room and jacked-off twice.So, you know what happened, right?

She might be getting fucked in the nearest alley or playing the centerpiece in a gang- bang in.
