Sensei No Koto, Kusugutte Ageru

I'll Tickle you, Sensei

Shuuma Aguri isn't like other high school boys. He doesn't get into sexual talks with his friends, and he sits alone. While he does have a secret fetish, he keeps it to himself - after all, who would willingly talk to a guy with a tickle fetish?

The only solace he has in his life is Anzu, a girl he met online who herself has a desire to be tickled. The two decide to meet up one day, only for Shuuma to find out that Anzu... is actually his teacher, Maiko Ogura?
