Looking back, the seeds were planted early. In high school, I had been popular and always dated really good-looking girls. Marsha worked at a drug store in my neighborhood, she was awkward looking, but with a great personality. She was fun.
The first time she asked me to take her home, I had her top off in the car and we made out, it was so hot. By the fourth date, I had popped her cherry and we played and fucked at every possible opportunity for the next two years.
At first, I took a lot of teasing from my friends who did not thing she was attractive in any way but I loved that she liked to take risks sexually. I liked the thrill of having sex in places where we might be caught and several times, we did. I also liked that I could be very dominate, calling her a slut while pounding her pussy and it just made her hotter. When we found out she was pregnant we got married immediately and the first three months it was heaven because we had our own place and we fucked two or three times a day.
About the fourth month, she told me that it was getting uncomfortable for her to have sex and suggested she could help me get off other ways whenever I wanted. I found this to be less exciting but she began whispering her fantasies about fucking other men while she massaged my prostrate and sucked me and it became addictive. I would encourage her to come up with fantasies that are more outrageous. I actually began to like this kind of sex. By about month eight she was becoming more uncomfortable and began asking me to please her orally as well. I was happy to do that for her. About this time she had accidentally brushed her nipple across my cock and when I sucked it I mistakenly thought it was milk and told her how good it tasted. This was the first time she had ever laughed at me in bed. That became a staple of our sex life after that, me licking precum from her nipples and I began to like the thought.
The last month of her pregnancy, she turned into a real bitch. She demanded oral from me and would straddle my face, her big belly covering me as she ground her pussy over my tongue. I found it exciting that she took charge and demanded service from me.
