College girl Rie writhes under the cold, relentless assault of a masked man. A vibrator is pressed against her soft pink nipples, causing her to tremble from the unfamiliar sensation—yet she can't suppress the pleasure, moaning helplessly.

Her legs give out, kicking feebly into the air, her eyes rolling back—her helpless state a testament to her tormentor's dominance.
