I was happy for that -- as much as I love the City, a New York accent grates on me."Steffi," I continued, "I'd like to get to know you before then. Ar... you by chance free tonight?" Sure -- not a problem."I gave her my address and she said it would take her about twenty minutes.I pressed the intercom. "Doorman," came the reply."Ralph -- I'm expecting a visitor. A lady named Steffi." Steffi ... got it Mr S."While I was waiting I removed my tie and loosened my shirt collar. It was more like half. As I was getting into my room I felt the tingling and I watched as my dick grew back out, my tits shrank, my hair shortened, my nails shrank and my hips retracted. I was now Jason again, so I had to hide my sisters clothes. Just as I was putting my sisters clothes away I started to feel hot. It was happening again. I watched as my hair on my hands receded, my nails grew out, then my hips and ass grew out. My body hair receded, my breasts re-grew back out to their 38 d size. I watched. My cock head pushed in ever so slightly. Mary pushed her ass out toward mepushing my cock deeper inside her.I wasn’t ass fucking her, her ass was fucking my dick.We pushed together as one and I was completely inside her.She was so fucking tight, it was unreal.Slowly I pumped it, fucking her ass. She groaned so hard I was afraid she would led out a scream. Her hips were gyrating like crazy. I could hear her grunting, keeping herscreams in, so our parents would not hear. I was fucking her so. This was not my intention when I came to meet tonight.”“There is no need to apologize. Your honesty was very believable and quite charming,” as he pushed my hair away from my face. He walked back toward his desk and started putting things into his bag to leave.“Please remember to tell your friend that his C- is now a B. Have a nice evening. It was wonderful getting to meet you Jenni.”I was free to leave but I didn’t. Maybe it was the bent up frustration. Maybe it was the moment or just that it.
