Married woman Yū is lost in erotic fantasies, masturbating while wearing a leotard to stimulate her body. As her fantasies escalate, she awakens to find herself restrained and tormented by a vibrator, forcefully releasing a large amount of urine. A forcibly erect penis thrusts into her, engulfing her in intense, overwhelming orgasms. Keeping it a secret from her husband, she works part-time at a delivery health service, changing into red lingerie to seduce her clients and fulfill their wildest desires. She is fingered to squirting orgasms, climaxing repeatedly like a bitch in heat, and ultimately gets pounded hard and brutally creampie fucked. This intense progression drives her pleasure to even greater depths.
