[Korosuke] Secret Pervert Instruction [Full Color] [Decensored]

Busty schoolgirls Ohno and Kotomi discover their older teacher Mr. Shimoda has a secret, hands-on curriculum that follows them from empty classrooms to the packed rush-hour train. With relentless whispers, his tongue and hands tease and squeeze their soft, heaving big breasts while his hard cock grinds and thrusts against their panties, turning their flustered protests into trembling, panting surrender. Caught between the fear of being noticed and the shameful heat of fingering, cunnilingus and brazen chikan groping, each coerced lesson blurs resistance and arousal until they can no longer tell if they want him to stop.
