Pervy Dandere!! is a story of introversion, young love, and sex. Lots and lots of kinky sex.

You play as William Jones, a fairly average, if a little awkward, young chap who is madly in love with Hanako Tanaka, the most impenetrable girl in school. One day, he finally musters up the courage to ask Hanako out and. . .she accepts? Not only that! They end up fucking the same day. Good man, Jones!

But our MC soon finds out that all is not fun and games. For beneath Hanako's reserved exterior is a perverted lust for sexual deviancy. She wants to try a little bit of everything, and Jones is her guinea pig. Join the young couple in their journey of sexual exploration, and see how they grow through the unique bond they share.​
