New teacher Sara Saijo is assigned to be mentored by male faculty members. Despite feeling uncomfortable, she's forced to wear a sailor uniform that looks too juvenile for her age, has a remote-controlled vibrator secretly inserted into her panties, and is made to walk around school while being toyed with. She's taken to the infirmary where she's penetrated while being sexually teased. Deeply masochistic, Sara becomes aroused despite the degrading treatment. Two other male teachers accidentally discover her situation, leading to even more intense sessions. Eventually, she's restrained in a barred room where her sensitive clit and vagina are relentlessly stimulated. The male teachers repeatedly bring her to the edge of orgasm and then stop, forcing her to endure prolonged denial to amplify her pleasure. Her vagina leaks copious amounts of cloudy arousal fluid as a result. In the end, Sara desperately pleads, "I'll do anything—just let me come," begging for release.
