I bought condoms and the gal from my class turned into a onahole, and then the gal's mom was a pure submissive masochist.

Keito Saiki, a conscientious introvert who always used condoms when using a onahole, bought condoms at the drugstore and was spotted by Marua Shishido, the gal from his class, known as Rua.

Due to Shishido's pushy nature, he ended up lending her six condoms.

When Monday came around, Shishido returned the condoms, but each of the six was in a different package.
