Sana, who's been hiding the fact that she's actually a boy, enjoys her school life. One day, she's suspected by the principal of being a boy. When her bulging crotch is pointed out, Sana refuses to admit it. However, when her crotch is stimulated, her penis instantly becomes erect, leaving her unable to make excuses. Her lies are exposed, putting her at risk of expulsion. To stay in school, she must obey the teachers' orders. She's manipulated in the classroom for a 3P, and in the nurse's office, she's given suspicious drugs that make her body hypersensitive. On top of that, she's restrained and her clitoris and ass are toyed with, causing her to scream in ecstasy as she orgasms from both ends!
