GG-002 Mom's real sex education Momoka Nishina

Kazuya, an idol otaku, was disgusted by his young and beautiful mother being looked at sexually by his friends. However, one day, he witnesses his friend Tadashi rubbing her mother's big breasts and forcibly giving him a blowjob. Since then, Kazuya begins to think of his mother as a woman, and becomes more interested in the bodies of women around him than idols he can't touch. He invites her mother, saying, "I want to take a bath together for the first time in a long time."
