Rei Aino, a 27-year-old receptionist at a major department store. She has a calm demeanor and a gentle, composed expression. Her refined voice warmly greets customers with a polite "Welcome." Though she appears elegant and unapproachable at first glance, beneath her desk during work hours, she secretly pleasures herself with her fingers. Maintaining a poised facade while stimulating her clitoris, she's a hardcore pervert who can't resist even as customers walk by—revealing her true nature as a born exhibitionist. But there's more to her secret life. During her lunch break, she heads to a hotel to indulge in sex. She craves cock as a way to relieve stress, getting tied by the neck with chains while still in her uniform, serving her partner like a devoted female dog. She savors fleeting ecstasy, her entire body lifted toward paradise. Her tight anus clenches as she endures spanking from her man, whimpering between sobs. Delicate women like her climax intensely and repeatedly, arching her slender body in violent orgasms. She squirms countless times throughout her workday—completely addicted. Her nipples swell to about one centimeter, hard and sensitive, relentlessly teased until she screams, "Ah, more, more!!!" She's violated by a woofnizer as a daily greeting, her pussy dripping wet. Penetrated raw, her cervix is pounded hard and fast, thrust after thrust, until she's lost in pleasure, staring blankly into space, moaning "Ah, perfect." Thick cum oozes from her slit as she tosses her hair in ecstasy—a genuine, unapologetic pervert.
