While I lay on the treatment chair doc was gettting hard again staring at my naked body, he got on top of me and started kissing me and suddenly we h...eared a knock on the door, "hey it's me Seema, can I come in?" and I just shouted, "yeaa please" and she opened the door to find the doc on top me. She quickly closed the door behind her. She was wearing a blue loose shirt and a black loose skirt. She walked up to me and said, "I thought you had finished", and she kissed me and watching us. ” “Am I very clear?” Susan was so turned on by the by Bill’s description, it would not have taken much more than a stiff breeze across her clit to take her over the edge. “Yes… Sir.” She swallowed the rest of her wine. “Tell me you want to be my slut.” “Sir, may this girl be your slut.

Your elbows should be held back as far as you can.” Her dress rode up her thighs enough to see the tops of her stockings. “Remove your dress. Fold it. It took the pressure off my breasts and held them from rocking. It seemedreally strange to see my own chest look this way.Next, Kathi told me to lift my arms and drew a matching camisole over my head. I loved the silky feel as it came down my hairless body.

I can't wait for you to see it," he said breathing heavier and bouncing up and down like a school kid.I spread the zipper and his cock was straining to get free of his boxer briefs. I pulled the flaps of his pants down and apart. I seemed to be sweating as I took my right hand to his waist band, pulling it toward me. With my left, I slid inside his waist band, between his cock and belly, grabbed his dick.
