"Look at My Nipples, They've Grown So Big!" A Quiet Woman Driven Crazy by Nipple Play, with Pervertedly Big Nipples More Sensitive Than Her Clit - Kokono Isanao
During a university drinking party, a man passes out drunk and wakes up in the room of his senior, Kokono Isanao. There, he discovers her secret hobby of "nipple training masturbation" and ends up in a relationship with her that he can't tell anyone about. Time passes, and the man gets a job at the same workplace as Kokono. The two continue their secret relationship. Her nipples, which have been trained to be even more sensitive than during their student days, have become pleasure organs surpassing even the clitoris! Furthermore, Kokono also trains the man's nipples just like her own. A woman gets wet watching a man driven mad by a completely different kind of pleasure from a dick. The culmination of a woman's terrifying record of perversely pursuing nipple training reaches its peak here.
