Mayuko works at a pharmaceutical company involved in new drug development. In her workplace, where mistakes are not tolerated, she maintains a calm and flawless demeanor. With dark hair, black eyes, and a sharp, elegant appearance, her look is professional—yet the cleavage visible when she looks down is something no one can ignore. Six months ago, her fiancé broke off their engagement due to debt issues, leaving her struggling with emotional stress and pressure at work. Seeking relief, she turns to dating apps and singles bars, seducing men to satisfy her sexual desires. But casual sex with her fuck buddy no longer satisfies her. When she tells a man she "loves cock," he immediately forces her into a blowjob. Using incredible oral skills, she nearly cums, then takes a short break. During solo masturbation, she starts with creampie, clearly enjoying fantasy play—just touching her nipples makes her moan, climax, and leave wet stains on her panties. When fingers stimulate her pussy or her nipples are massaged during assisted masturbation, she screams in pleasure and reaches orgasm. She’s then tormented with a vibrator, dildo, and electric massager. Once penetration begins, her hypersensitive pussy goes wild, losing all control as she chases intense, mind-blowing pleasure, climaxing repeatedly, completely forgetting her real life. In the second half, wearing a lab coat at her research facility, she acts out a fantasy: "I want to wear an office lady uniform and do dirty things at work." Bound and vigorously pounded, her body succumbs to the surreal eroticism where reality and fantasy collide. Drooling from both mouth and pussy, she writhes and cums uncontrollably—an insatiable, depraved woman.
