The story is like this. There's an exorcist guy (looks a bit shota) and his girlfriend. The guy goes to a village to exorcise Tengu demons, but gets caught by them. Then the girl goes to rescue him but the tengu demons use him to make her surrender. They then proceed to fuck her for many days and try to break her. Then they allow the guy to have sex with her. But the girl doesn't feel his tiny dick at all. Then she breaks up with him and gets addicted to tengu dick.
