When She Harasses Her Innocent And Super Shy Sister-in-law Day After Day, She Becomes Super Sensitive And A Premature Ejaculator, And Comes All Over The Place! She Turns Into A Perverted Girl Who Comes With A Vulgar Face. Miyu Hou

When my parents remarried, the stepsister I got was... a timid girl who couldn't clearly say 'no' to things she didn't like. At home, she was so careless she didn't even wear a bra... As I stared at her, I couldn't hold back anymore, and every day I'd poke, poke, poke, poke her nipples through her T-shirt... rub, rub, rub, rub... Taking advantage of the fact that she couldn't refuse out loud, I kept up the nipple harassment day after day, and her reactions kept getting stronger. Her p*ssy got soaking wet right away, and she completely became an ultra-sensitive, premature-ejaculation type. In the end, she transformed into a lewd girl who would even come ask me to touch her nipples herself!!
