Takashi, the older brother of a part-time worker, has a younger sister, Kotone, who is a shy high school girl and doesn’t talk much.One day, when I casually used the “stimulus ray” I borrowed from a friend on my younger sister, her nipples became 100 times more sensitive than normal people…Since then, Kotone’s daily life has completely changed.The stimulation to her nipples doesn’t stop and she ends up incontinent while making a disgusted face.The older brother, Takashi, cannot contain his excitement at the sight of his sister’s completely changed appearance, and continues to pour out his pent-up sexual desire on Kotone.He relentlessly tortures her nipples almost every day, makes her cum over and over again, and makes her repeatedly show off her expressions and incontinence.Once it was over, he would pretend nothing had happened and erase his memory…#ChinP
