Gal Nipa-chan wa Semararetai

The popular teen model niPA, aka Futaba Asahino, is strong willed and refuses dance by someone else's tune, but the plain guy who is her seatmate refuses to budge before her... "Damn that four-eyed nobody, how dare he tell me off!" But at the same time, remembering that makes her feel somehow strange. Her fingers slip beneath her skirt as if by reflex and while thinking about getting assaulted by that disgusting man she pleasures herself against her better judgment while she is brought to climax in her fantasies!?
