This is the story of Nao Wolfsbane (♂), whose libido goes haywire because of a drug his sister gave him.
This is the first time I’ve ever seen a girl with a big stick in her hole.
This is the first time I’ve ever had the pleasure of watching a girl get fucked by a man.
I’ve had so much semen poured into my womb that I’m sure I’ll get pregnant many times. (Mild Ver. does not have a belly button)

This is the first time I’ve seen this movie.
