Because of my parents' remarriage, I suddenly gained a stepsister. And she's an incredibly cute, busty high school girl. She's timid and unable to clearly express her opinions. Of course, she can't refuse my constant nipple harassment and can only be manipulated… Day after day, constantly subjected to my nipple harassment, her nipples are developed to an extraordinary degree, becoming hypersensitive. Just as her supposedly hateful appearance is a lie, she herself comes to me, wanting me to touch her nipples, transforming into an extremely lewd woman!
