One day while I was outside in my front yard, one of my neighbors (a girl) and her friend (also a girl) came over and asked me if I could help them with their homework. Seeing as it was summer, I thought it was an odd request, but I decided to play along. After going in her house and walking up to her bedroom, she locked the doors. They then told me that they needed help with a college-prep assignment for health class. They claimed the assignment was for them to have sex before their first college semester. So, slowly they removed their clothes to expose their huge boobs. Then they sat me on the bed and gave me a lap dance. Then, I stripped for them, and I had the best threesome of my life. Now, eight months later, I find out that she is pregnant.
