Taken out of my shell

My mother always said I was awkward and quiet growing up. But I lacked self-confidents and was shy around strangers especially females. Always put down by my siblings as a nerd, geek or retarded. They unlike me done well at sports or anything else except their studies. They didn't go to university, and I did, as the youngest of 3 boys. They called me a mommy's boy, but not when she was around. Anyway, I got into university and was called geek or nerd there as well. My life changed when one of my professor's appointed me to assist her. She was 56 widowed and had a reputation as a strict no-nonsense professor. I was top of the class and so being appointed to assist her was a surprise to anyone. Most of the class were glad it wasn't them chosen and I liked looking after the experiments she had going. Then one weekend she asked me to drop by her home to assist with an experiment. I turned up at 9am as requested and we worked on the experiment all day and it was dark outside and she had me stay for dinner and it started to rain lightly by the time dinner was finished. As I was required again next day, she said I might as well stay the night. I wasn't looking forward to walking home in the dark and so I stayed. I went to bed in the spare room and several hours later I was awoken by her getting into bed with me. Being timid by nature I done what she wanted and that was let her fuck me and she drained me twice. The experiment wasn't top on her agenda the next day as it was the previous day. Getting me to fuck her took the top spot and I was totally worn out when she dropped me back to lodgings at 9pm. Helping her after lectures and on weekends became normal for me. Fucking her was also great for myself image and the shell I had built up around myself cracked and finally shattered completely. I had confidence in myself and able to mix with other more than ever before and my fear of girls disappeared not completely. But I wasn't frozen like a statue when they were near me anymore. I finished university and my ball draining professor got another job on the other coast. Within 3 years of graduating, I was married and now have 3 children all girls. All thanks to my professor.
