MISM-050 I've become a masochist. Every morning and evening, a super perverted old man with an overloaded dick brain rapes and inseminates a new OL every time she returns home, flooding her with dopamine and brainwashing her into becoming a masochist, mak

A newly independent, super straight-laced new office lady turns into a super masochist! Is it good luck or bad that her next-door neighbor after moving is an ultra-enduring, bottom-of-the-barrel old man! Instead of greeting her, he sneaks into her home and gives her a throat fuck until his balls are empty, finishing inside her in a brutal rape! It doesn't stop at just once; every morning and every night, and even when she's at home, she continues to be raped. Her marrow is brainwashed into masochism by Ayachan! Without missing a beat, she undergoes fleshly training, surpassing masochistic awakening and falling in love... Such a wonderful love story.
