爆乳ママ孕ませ寝取り ～極悪少年のママビッチ化計画～

The protagonist pretends to be an innocent kid all along, but in reality he's been fucking countless female students and teachers on campus silly!

It's the first day of the new school year in spring. The protagonist goes to visit his friend's, Misao Hijiri's, house. Inside of the house, he spots Hijiri's mom. Her giant, voluptuous breasts and banging body make him seriously horny.

Obviously, he thinks about making a move on her, but the consideration that it is his friend's mom keeps his urges in control.

However, the next day, the roles are reversed: Hijiri comes visit the protagonists house, falling in love with his mom and her own banging bombshell of a body. The cute boy's honest feelings are a flattery to her and she doesn't dislike it.

The protagonist is furious and devises a plan: "I'll take my mom back and snatch Hijiri's away on top!"
