ROYD-338 I've been sexually harassing my clear and super shy stepsister every day, and she's become super sensitive and prone to premature ejaculation, cumming non-stop! She changes into a perverted girl with a vulgar face, cumming non-stop. Satou Aru.

Because of my parents' remarriage, I suddenly got a stepsister. She's incredibly cute. And she's quite weak-willed. Easily influenced by those around her and terrible at saying no. So I decided to mess with her every day. Morning, noon, when she's sleeping, even when she's in the bath… So how about that, they came asking for us to snitch on them! She's become so horny she can't live without snitching. But she also grew up enough to clearly say 'I want you to touch my nipples.'
