As it turned out, my sister Ayaka Tomoda was not only an AV actress but also a technical instructor for the adult industry and hostess clubs! When she needed help with her job, she called upon me to fill in as a male model substitute. Dressed under a sheet with just my erect penis exposed, I couldn't resist cumming all over myself as she showed off her incredible techniques. To make matters worse, afterward, some of the students even played with my spent cock, sending me into ecstasy! Despite being a lecture on How to, we ended up with nothing but premature ejaculations... #classpresident
