Takashi, a freelancer, has a quiet and reserved high school student sister, Kotone. One day, he casually uses a "Hypnosis Ray" borrowed from a friend on her, and her nipples become 100 times more sensitive than a normal person's. Since then, Kotone's daily life has completely changed. The constant stimulation of her nipples leads her to lose control of her bladder while wearing an ahegao expression. Takashi, unable to contain his excitement at his sister's transformed state, continues to pour his pent-up sexual desire into Kotone. Every day, he relentlessly attacks her nipples, making her cum multiple times, repeating the cycle of ahegao and squirting. Once finished, he uses hypnosis to erase her memory, making it as if nothing ever happened... #DickP
