"Thank you for dinner and for tonight. I had a lot more fun than I thought I would," she said. I smiled at her, "So did I. To be honest, I was dreadin... this reunion. But a couple co-workers and friends made me promise to come. And I'm glad I did." Once we got in the car, I turned to her. "Where to now?" I asked. "I don't know. I don't have to rush home for anything - unless you do?" she said. "How about just going for a little drive then?" I suggested. She nodded, smiling. So I put the car in. I felt this hands on the back of my head as he pushed his cock down my throat until my lips were firmly pressed against his pelvis. He then began to move my head back and forth over his cock pausing for just a few seconds every forth or fifth stroke to let me breath.I was completely relaxed now and really enjoyed the feeling of his cock sliding so easily back and forth in my throat somewhat forcefully. He pinned me to his pelvis and said “Oh baby, you have no idea how good this feels.” He then. That is because they are mother and son. Yes, Aunt Jane is my mother, and therefore she is really your grandmother. I'll stop for a few minutes to let you digest the information up to now."I was stunned. People I have known all my life as my aunts, uncles and cousins, turned out to be something entirely different from how I knew them when I was growing up. My Aunt Jane is really my Grandma, and she lives with her son as husband and wife, and they have children too. The same about Aunt Clare and. After he left I just sat there in a whirlwind of shock not believing what had just happened. So many thoughts raced through my head. Why did I let him do that? Why did I seem to like it? Did anyone see? Should I just run out of here? Where did he go? Why did he just leave? Was I doing something wrong?I found out soon enough because he was only gone about 2 minutes when he walked back in, pulled out his now soft cock, grabbed my head and shoved his cock back in my mouth. When he started fucking.
