The life of a college student is never easy. But when an upperclassman introduces Atsushi to a nice girl in need of some tutoring, life is about to get a little more rewarding for him. Not only is he spending time helping out a cute coed, but she happens to have a sexy mother to boot. Little does he realize at the time that the two will fight over the slide rule in his pants.
