A big-breasted married woman is pinned down by her lover and locked inside a closet. Her sensitivity is heightened, forced to endure unbearable stimulation. Her body remains extremely sensitive—just having oil dripped onto her and her nipples teased causes her to scream, "I'm gonna cum!" and thrash wildly. With a gag in her mouth and her limbs bound, she's completely restrained, unable to escape. Unable to withstand the relentless vibrator torture, she drools uncontrollably while shrieking in agony. Straining her voice, she pleads, "Onegai shimashu..." begging for mercy, and once the real thing finally enters her, she loses all control, trembling in overwhelming ecstasy.
