"Slave contract - absolute obedience to the orders of a creepy guy."
Ishida, a creepy geek who is hated in class, takes a liking to Nao, and she loses her virginity to him in a despicable trap. Nao tells Ishida that they should forget about it, but Ishida's twisted mind is rather pleased that they have more secrets, and he begins to treat Nao as a lover. Nao, unable to resist Ishida's grasp on her weakness, leaves class on his orders and continues to be drenched in his white fluid on campus...!
