The temptation and allure of sex can be very overpowering, leading people into situations that they never could've imagined themselves being in. HHH Triple Ecchi reveals three of these sexual expeditions across four short stories. Parts one and four showcase the blossoming relationship between the beautiful and talented Shigure Takashima and her soon-to-be lover and classmate, Komatsu Kita. When Shigure's lust and fetishes get the better of her, compelling her to please herself in the classroom after class, she had no idea that Komatsu would stumble upon her while cleaning. What could've been a nightmare for Komatsu turns into a never-ending amount of sexual adventure with Shigure's insatiable sex drive.
