I am not anything big- just an average 6 1/2" and not real fat. I figure that is why I love being a bottom for Chris! But, I get to take him in the ba...ckside on occasion. (Chris is 6' tall, about 170# and very fit. He has also helped me get back in shape. I'm 6' 2" and now down to a trim 190#.) I knew that this weekend there would be a lot of backside action for all of us! I went in the house to grab some seasoning and found Terri leaned back against the kitchen counter with Sandra on her knees. Neither of us had any idea of what she was doing.Then Al stood on the bed & started doing a slow bump & grind dance,with teasing brushes over her tits & her crotch. She looked at us & asked if we liked what we saw. Naturally we both said hell ya, she said well it's going to get better. I'm standing there thinking what the hell is she doing.In a flash she got out of her clothes,standing there bare ass naked, then she laid down right in front of Jack,legs spread as far apart as she could get. “Okay, b*tch, time to get serious with this sh*t!” Big said as he pulled me up and off both the chair and his cock and took me, by the throat, over to the bed, with Senior in tow after us. There was a knock at the door. The girls were here.Senior stepped towards the door, but stopped dead at Big’s, “Leave it-I think we got the only b*tch we need right here; and she won’t charge us by the hour!” Oh my, what HAD I gotten myself into? I thought in the most delicious anticipation. In the stall. As she washed her hair, she didn’t have a care in the world, then she started washing her face and neck, I was sat on the toilet lid a few feet from her, even though she had took a fall and was injured she was in good spirit and singing, she then turned to me and splashed me, I told her off, but not sternly, she splashed me again, looking down at my shirt I told her she was getting it all wet, she laughed and splashed me again, “Stop it, I’m all wet” “Don’t care” and she splashed me again,.
