Because I was younger and Nathan older our sexual intercourse seemed to be appropriate. While Nathan fucked me I asked him was comfortable in his butc...h role, Nathan answered "Surprisingly so", I having as much enjoyment fucking you as if I was being fucked. We changed positions to a 69, where we both sucked each other cocks, then I sucked and savoured Nathan's cock until he exploded his sperm in my mouth then Nathan did the same to my cock and swallowed every sperm droplet I excreted. Both of. Our lips touched, our tongues caressed. I flexed my finger inside of my wife and I heard a slight groan escape her lips as she release the hold on my hand. I then moved my wife on to my lap and she positioned my cock between her legs. I then pulled the fabric of her bikini bottom to the side and let her guide me to her opening. I could feel the resistance of her flesh give way as the head was aligned with her opening. A small move from me and a move from her and I felt oily smoothness engulf. "That's so fucking hot," I heard Lizzie say. She seemed to find another gear and started slamming her dick into me. I came for a second time from Lizzie's cock."I'm gonna cum," she said. "I'm gonna blow."She pulled out and grabbed her cock. She grimaced as if he was trying to stop it from happening, but it was too late. Her cum splashed onto my stomach.With Lizzie out of the way, Christie straddled me. She leaned forward and our breasts rubbed together as we kissed. I slid two fingers in her. Don't worry son it will be nice and full I've haven't nutted in two weeks. I looked at my wristwatch and noticed that it was 6 p.m. I had about an hour before Deb would be home.I went back to my car and waited and after about thirty five minutes the old man made his way out of the bookstore and slowly limped to his car. I meet him there he was grinning as I walked up to him."It was a good day for me, some fine movies in there today a lot of them with pretty white girls and black guys." he said.
