ROYD-338 · Nipple Harassing My Shy Stepsister Until She Becomes a Sensitive, Cumming Pervert - Meru Satou

I suddenly got a stepsister because our parents remarried. She's incredibly cute, but also very timid. She's easily swayed by others and can't resist a strong push. So, I decided to nipple harass her every single day. Morning, noon, while she's sleeping, even in the bath... And guess what? She started begging for it herself! She's become such a slutty girl that she can't live without nipple harassment anymore. But she's also grown enough to clearly state her opinion, like saying, "I want you to touch my nipples."
