We used to fantasise about it, and when he was away I’d fantasise alone with a big dildi.I slowly got my self ready, black jewelled suspender belt, ...rand new black fully fashioned Cuban heeled seamed stockings. A tiny black thong and matching quarter cup bra just about supporting my big tits, my regular black pencil skirt with a six inch back split. This was topped with a white silk blouse which I knew would rub against my nipples keeping them good and hard. I was almost ready just my lashes. She left her entire back on the counter while he was thrusting her like a wild beast and got naked.After a while, due to the pleasure, she was moaning with each thrust.

I went to the room door.. They jumped into the back seat and thanked us for stopping. They then introduced themselves. Jim was driving and the girl behind him was Sam (Samantha). She was a little taller and slimmer than Karen, the girl who was sitting behind me. Sam was about 5'7", slender, and had a nice set of what looked like 'B-cup' tits. Karen, on the other hand, was about 5'5", nicely rounded with a little, but not too much fat. She had a great set of what looked to be 'C-cup' tits.Sam said they had left.
