J◆'s girlfriend, Erika, is an 18-year-old with F-cup breasts and a shy, reserved personality. Even holding hands on dates makes her uncomfortable, and she often pulls away slightly—her behavior surprises J◆. They had planned a romantic date in Asakusa, but as usual, she's bashful and avoids any physical contact. J◆ decides to invite her to a hotel, hoping to create an intimate space where she can open up both emotionally and physically.
At first, her demeanor doesn't change much after arriving at the hotel, but gradually she begins to relax and let her body respond. When a vibrator is applied to her smooth, plump thighs without warning, she suddenly orgasms externally with no control—her carefree reaction angers J◆, prompting him to force her into a blowjob. Her wide, innocent eyes looking up during the blowjob create an intense sense of taboo, fueling his urge to penetrate her.
Unable to hold back, he proceeds to creampie her bareback. With no condom available, he thrusts into her in missionary position, spreading her into a wide M shape against the window overlooking Asakusa, fully exposed to surrounding buildings. Though she was self-conscious about public attention during their date, she's now completely lost in pleasure, accepting creampie after creampie inside her womb while still dressed in her uniform—her expression resembling that of a virgin's first time.
It turns out this is her first-ever bareback creampie. To mark the occasion, he strips off her uniform without letting her rest and immediately starts round two. Lacking sexual knowledge due to her youth, J◆ gently guides her through it. Surprisingly, when receiving titty fuck with her large, firm breasts, she seems to embody the best of voluptuous women. Once her erotic switch is flipped, she starts eagerly grinding her hips onto his cock.
Sensing her passion, J◆ begins making love to her tenderly. Watching her shift from passive receiver to actively riding him in cowgirl position, he realizes her immense potential. Her youthful body quickly adapts, swallowing his cock with ease—making her incredibly satisfying to fuck.
To make up for the earlier lack of intimacy on their date, he makes her climax multiple times internally before forcing a second bareback creampie of the day. Afterward, she says, "We don't even need dates anymore." From now on, he plans to call her out solely for sex.
