Mirei Nitta's birthday has arrived, and she's thrilled beyond words when her beloved boyfriend surprises her with a romantic celebration. Handsome and intensely dominant, he's determined to make this day unforgettable by turning his sweet, submissive Mirei into his completely obedient lover. As planned, they head to a hotel where he restrains her tightly, leaving her helpless and completely at his mercy. He slips her an aphrodisiac, heightening her senses and deepening her submission. Under the drug's influence, her body becomes hypersensitive—sweat and arousal dripping uncontrollably. Blindfolded, her sensations sharpen further, her lower body trembling violently like a startled fawn, reacting even more intensely than usual. Bent backward in ecstasy, she screams as she's pounded with relentless thrusts, reaching multiple orgasms while deepthroating his cock, saliva drooling down her chin. The aphrodisiac makes her clit fully erect, and when hit with the vibrator, she experiences an unprecedented, explosive squirting climax—soaking the sofa and floor, drenching everything so thoroughly it feels like the next floor might flood. In this delirious, drug-fueled trance, she arches with a dripping ahegao face, convulsing in orgasm after orgasm as his thick cock rams deep into her pussy. Fully transformed into an insatiable, hyper-sexual beast, this is the day Mirei becomes a complete aphrodisiac slut. The main feature includes facial exposure, capturing her rawest emotions and authentic physical reactions in vivid detail.
