After our parents remarry, I gain an adorable adult stepsister. She is timid and cannot refuse a request, so I start sexually harassing her, teasing the nipples visible beneath her braless T-shirt whenever I get the chance, day or night. Whether through her clothes or directly, she is too meek to stop me even when she dislikes it. After days of relentless nipple stimulation, her body becomes intensely sensitive and she transforms into a drooling, horny woman. In the end, she finally speaks up for herself—by asking me to touch her again.
