A sadistic masseur lies to his underage schoolgirl patient, claiming a special medication will enhance the massage effects, while secretly administering an aphrodisiac drug. As the girl's consciousness grows hazy, he repeatedly engages in lewd acts, forcing her into fetishistic behavior by stroking his penis and bringing it close to her face. He then proceeds to lick her genitals, thrusts his penis inside her, and grinds his hips as he pursues pleasure.
