DASS-587 A mother and her son were locked in a room where they couldn't come out unless they ejaculated 10 times, so they resisted wanting to have sex with each other and ejaculated a lot. Kana Morisawa

Kazuma can't stop masturbating in his mother's Kana underwear. Kana, a perverted mother, gets excited by this and even makes him masturbate by soaking the smell into his pants. One day, when I couldn't stop myself from masturbating and wanted to do something even more disgusting, I went to an AV maker! I found a call for participants for ``a room where you can't leave unless you ejaculate 10 times'' in the project call for events, and I didn't tell Kazuma.
