Yoichi was writing his graduation thesis at the library, but while thinking about it, he inadvertently groped his nipples. Then Kana, the librarian who saw it, touched his nipple out of curiosity. Kana, who became amused by his overly sensitive reaction, couldn't stand it and relentlessly blamed his nipples to lead him to the climax. After that, Yoichi continues to be squid while being repeatedly groped by her nipples in secret. And one day I can't escape from the pleasure of his nipple torture.
