A middle-aged pervert and a girl's sinister day, driven by lust for a J-cup bust that exudes overwhelming presence even through a school uniform. The uniformed girl, unaware of the lewd acts being performed on her, has no idea about the importance of internal ejaculation as she is made to receive sticky semen deep in her vagina from morning till night. Eventually, the girl remembers the act, and the initial 'strange sensation' gradually turns into 'feeling good'.
