Movie description: "My Sister-in-Law Made Me Ejaculate Inside of Her! She Wanted a Smart Baby". I'm just a nerd who loves math and science, but I can't study something to approach girls, so I'm really inexperienced when it comes to sex. Everything changed when I was checking out my new book on quantum physics in my living room and my hot stepsister sat next to me. Before I could even do anything about it, she was rubbing my penis. Man, her hand on my dick felt way better than solving a math equation. "What do you want from me? ", I asked, so turned on I could barely speak. "I want you to ejaculate inside of me. " I was shocked! She was using me to have a smart baby. I know that should be wrong and I know that she was cheating on my brother, but come on, have you seen her body? This was my chance to fuck her and get my hands on those perfect tits and I was not going to waste it. She wanted my cum and she got it.
