The first time I went to her house, the J-system little sister she introduced was incredibly cute! With a bit of ulterior motive, I sneaked a peek into her room and saw her moaning and masturbating alone. When she noticed me peeking, she turned bright red and explained why she was masturbating. She confided that sex with her boyfriend wasn't working out… As encouragement, we decided to mutually masturbate, and on her first public masturbation, I immediately penetrated her as soon as she climaxed!
