>Yamashita, a university student, was interested in Makise Shiori, who was a fairly good friend of his in the same seminar.
>One day, he suddenly receives a photo of Shiori having sex with a man on his cell phone.
>The next day, Shiori comes to apologize, saying, "I'm sorry, I made a mistake when I was trying to send it to the group! You didn't save the image, did you?!" Yamashita honestly confesses, "I saved the photo...", and Shiori becomes flustered.
>When Yamashita went along with the invitation, "If you like the photo, will you become friends who share a secret...?" , he found a lewd Shiori there , completely different from the image of Shiori that Yamashita had had up until now ...
>Shiori was naked and entangled with the men in the same seminar, using every hole in her body, and Yamashita... "Kuishinbo" depicts a free-spirited female college student, contrary to her appearance.

Strange torrent naming.
It's a tankoubon. Not a doujinshi.
