When I was harassing my neat and super shy stepsister every day, she became super sensitive and ejaculated prematurely! She suddenly turns into a perverted girl who makes a vulgar face and cums all the time.

My parents remarried and suddenly I had a sister-in-law. Moreover, she is an extremely cute, big-breasted female student. Misao is a weak-willed girl who cannot express her opinions clearly. Naturally, she couldn't say no to my daily nipple harassment, so she just let it happen... Misao, who continued to be harassed by me day after day, developed her nipples to a strange degree and became hypersensitive, and suddenly she turned into a lewd girl who came to me and asked me to touch her nipples, as if it were a lie that she hated it so much!
