If anyone was watching they could clearly see my nipples standing out through the thin material. I also felt the moistness between my thighs. I rememb...red the thick feel of Mark's young cock. I knew the itch I felt could only be scratched when it was deep inside me.I stood below Mark's window and waved when I saw him looking out anxiously.Don't make any noise, I thought to myself.Hours seemed to pass and I was becoming hotter and more aroused by the second. Finally I saw Mark closing the back. Her nipples were pink in color. I placed my mouth and sucked them. She asked me to bite those erected nipples. I obeyed her orders and did the same. She was making sounds like haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa hmmmmmmmmmmmmmmm yeaaaaaaaaaaaaahhhhhhh yes D , that’s the way suck them more. I sucked both the melons for about 10 mins… Suddenly she got up from the sofa and asked me to follow her to the bedroom. But I was scared that someone may come. She realized my doubt and said, don’t worry my. I knew nothing about sex & for me jerking my cock is a funny exercise. One day I was in my uncle’s room and nobody is at home. I was searching for something and under the mattress I found an adult magazine, on which’s cover there was a semi nude girl. It was a shock for me and I started flipping pages. That was the first time I felt a hardon in my pants without touching my cock. I got ample amount of knowledge about sex and female organs and started looking for any chance by which I can watch. I had arrived about an hour early and was sitting at my desk when a few of the women started to arrive. They just looked at me and laughed. I was not the first man to arrive early on his first Topless Tuesday. They asked me when I had arrived and I told them. Again they laughed at me, checked a chart that was in one of drawers, and then said that Helen had won the pool.As my reward I watched the three women remove their blouses and then I got to unhook their bras for them. One was a front clasp.
