Himari Kosaka, famed for her I-cup breasts and 100cm bust, embarks on a steamy date. During a drive, she opens up about her first experiences and masturbation, slowly easing her nerves. She's surprised when handed the remote-controlled vibrator "Tobikko," but once inserted into her pussy, she reacts intensely, kicking off an exhilarating ride. Her bra is forcibly removed, exposing her large, sensitive nipples as they harden—her humiliating date officially begins. At a park, the director mischievously controls the still-inserted Tobikko, making it difficult for her to walk as she writhes with sensitivity, trembling with arousal under public gaze, repeatedly reaching "pissing orgasms." Even during lunch, the Tobikko runs wild inside her pussy, her body convulsing uncontrollably throughout the meal. Back in the parking lot car, she unleashes a fierce blowjob, swallowing a massive cumshot. Upon reaching the hotel, the Tobikko remains inside as she gets turned on in an outdoor bath. Suddenly, a well-endowed male star appears, immediately finger-fucking her into continuous pissing orgasms. As he gropes her huge breasts, she retaliates with exquisite titty-fuck and deepthroat blowjob. Her pubic-haired pussy engulfs his fully erect cock, launching into an endless loop of intense sex, culminating in a massive creampie. Back indoors, the Tobikko is reinserted, delivering double stimulation with vibrations and fingering, triggering nonstop squirting. Her marshmallow breasts re-erect his cock, which she mindlessly takes into her pussy, climaxing violently with gushing fluids, rolling her eyes back in ultimate ecstasy.
