The volleyball team coach at a prestigious academy pretends to give athletic massages to top students while secretly engaging in lewd advances. The innocent girls, their untouched clits stimulated, quickly become overwhelmed with arousal, climaxing, pissing themselves, and nearly passing out from intense pleasure. With each massage session, their bodies grow increasingly sensitive. They're made to grip the coach's rock-hard cock, forced to jerk him off until finally, they're vigorously fucked and filled with creampie after creampie. The scenario unfolds into an extremely erotic series far beyond innocent sports therapy.
