Five years after graduating middle school, Reira Hazuki and Miyamoto reunite and head to his place for a casual hangout and drinks. That night, Reira gets completely drunk and passes out, giving Miyamoto the chance to start touching her. Gently caressing her thighs and ass, he elicits soft moans from her half-conscious body. When he presses his cock against her lips, she wakes up briefly but, dazed and confused, murmurs, "I only feel it with my boyfriend..." while letting him tease her nipples. Her competitive nature flaring, Reira defiantly snaps, "I'm not feeling anything!"—kicking off a bizarre orgasm contest. As Miyamoto bombards her with vibrator play, making her hips spasm uncontrollably, he repeatedly thrusts his hard cock into her, creampie after creampie. A pure yet highly sensitive gyaru, Reira exposes her body in this strange turn of events—all under the guise of a class reunion.
