ROYD-360 · Daily Nipple Harassment Turns Shy Stepsister Into A Sensitive, Orgasm-Prone Pervert - Riho Shishido

My parents remarried, and I got a stepsister. She's incredibly cute, but also very shy and timid. Taking advantage of the fact that she can't properly refuse things she dislikes, I spent every day indulging in nipple harassment! By persistently touching her braless nipples through her defenseless clothing, she transformed into a perverted girl who feels so much she drools and reaches orgasm multiple times just from her nipples! In the end, she grew into a confident schoolgirl who can clearly state her own opinion, even asking me, "Big brother, I want you to touch my nipples!"
