During my school days, I found out that the busty gal classmate who constantly bullied and made fun of me was working at a certain delivery health shop. I came up with a plan and quickly called the shop to request her. As expected, the ill-tempered busty gal didn't remember me and provided a half-hearted service. When I tried to forcefully insert, she raised her voice, so I showed her a hidden camera and threatened, "Do you remember me? I'll tell everyone back home." Then, I began a revenge play of developing her sensitivity through creampie training!
