Shion and Souta are in the same seminar. Shion is a cheerful person and Souta is a cool loner. They had no contact with each other, but they hit it off when Shion missed the last train one night and stayed over at Souta's room.

Shion, who frequently stays over at Souta's room, happens to find a thin book that Souta had hidden in his room. When he opens it, she finds...

'Souta... your xxxx doesn't want to me leave my mouth."

"Shion! An, an, it feels so good, I'm going to come...♡” and a lot of unbelievable words!

What a surprise, it was an 18 banned doujin BL novel of Shion x Souta written by Souta!

Seeing Souta embarrassed, Shion gets excited for some reason and starts to play the same game based on the novel...!

A handsome cheerful boy x serious cool guy (actually a handsome fudanshi) unfolds the most naughty, throbbing, secret love♡!
