ROYD-364 · My Pure and Super Shy Stepsister Became Super Sensitive and Cums Instantly After Daily Nipple Harassment! She Transformed Into a Perverted Girl Who Cums With a Lewd Face. Miyu Aizawa

Because our parents remarried, I got a super cute stepsister. This sister of mine is a very shy and timid girl. Taking advantage of the fact that she can't clearly say no, I indulged in constant nipple harassment! At first, I just poked her nipples through her clothes, but then I touched them persistently day after day. She started feeling it so much she'd drool, transforming into a perverted girl who could cum multiple times just from her nipples! In the end, she grew into a confident schoolgirl who could properly express her own opinion, even saying, "I want Big Brother to touch my nipples!"
