Mai, a literature student at a prestigious women's university in Tokyo, is obsessed with fantasies of being taken and is constantly aroused. At a hotel, she willingly submits to blindfolds and light BDSM play, showing no resistance. Helpless and restrained, she screams in a tearful voice, "I'm sorry, please stop," as she's tormented with a vibrator. Her reactions border on ecstasy—so wet she leaves stains on her panties, and during penetration, her pussy clenches intensely, passionately begging for positions like doggystyle.
