ROYD-335 I've been sexually harassing my super shy and pure stepsister every day, and now she's become super sensitive and comes quickly! She turns into a perverted girl with a dirty face, coming non-stop. Shinonome Rin

A sister-in-law who suddenly appeared due to the remarriage of her parents.A shy girl who can't express her opinion, a timid girl who can't clearly say that she doesn't like something.As I was sexually harassing my sister-in-law on a daily basis, her sensitivity increased dramatically to the point where she couldn't live without it, and in the end, she came to my older brother on her own, and this is a record of her growth from a shy girl who couldn't even express her own opinion to a girl who asked him to touch her nipples with her own mouth.
