Kurumi Suzuka is a horny girl obsessed with masturbation, indulging three times a day, totaling 21 sessions per week. When she tries a timer-equipped vibrator for the first time, her emotions quickly unravel. She cries uncontrollably, babbling incoherent words, rolling her eyes, drooling, and orgasming repeatedly. The special feature of this video is a unique setup where a penis-shaped attachment is mounted on the vibrator, inserted and secured inside her, while she's bound with handcuffs. Over the course of one hour, she receives continuous, random stimulation without pause. Her natural body and precocious erotic reactions feel incredibly real, creating an immersive experience that vividly mimics actual sensation.
