Because of my parents' remarriage, I suddenly got a stepsister. She's incredibly cute with this amazing transparency about her, and honestly, I wanted to do something about it. My sister is quite shy, can't say no, and can't express her own opinions; she's a coward. So, even if I touch my little sister's nipples every day from morning till night, she doesn't complain but starts to get aroused and even drools while reacting with shivers... Her nipple sensitivity keeps increasing, to the point where she comes to me herself asking for her nipples to be touched. You have a boyfriend? You're fucking perverted.
