She knew that I had cum and just smiled as she fell over next to me.I was stunned, I had blown it – came before I even had a chance to fuck! I stum...led though an apology and she kissed me and pulled me back up to go for a swim. The water was great and we waded out up to our chest. I dropped my trunks to wash out all the cum, wondering if it would attract any curious and hungry fish. I think she knew what I was doing because she reached up from behind me and wrapped her hands around my balls. "One, two, three..."I unwrapped my towel and put it on the floor, as Sylvia did the same. Sylvia blushed and looked away from me. I stared straight at her body. It became immediately clear to me that this game was not as "balanced and fair" as I had thought. I was wearing solid colored boxers. Sylvia was in a white bra and panties. It was apparent that, probably due in part to the alcohol, she had not thought through the "we'll have our underwear on and no one can see anything" concept,. She laughed at me and said, “My son is a grown man now.”One afternoon when my dad was at work and my sister had gone to school, my mom took me to teach me as I was very weak in my studies. I told her to wear a transparent nightie so that it will be easy for her as it was summer and we didn’t have AC at home.She looked shocked after hearing this and at that moment, she understood her son’s crush on her. She asked, “Beta, I am your mother. Don’t you dare start looking at me in a lusty way.”After. I did manage to get a head count of the number of guys there, excluding my brother , she won't fuck him because she just wouldn't. There was fourty one guys , thirty four had wifes with them, and six where black. Roger from my wife's work was one of the black guys. After midnight the married couples started to thin out , I was getting Happy Birthday kisses from the wifes as they where getting reasdy to leave. I was haveing fun. Soon it was down to the last "hard Core" party guys, the single.
