Mihitsu no Koi – Episode 1 (ES)

Yuka, a cool and athletic schoolgirl who dotes on her best friend Risa daily, harbors deep resentment toward Risa's older boyfriend, viewing him as the man who "corrupted" her gentle, plain, and serious friend. Risa adores him openly, sharing lovey-dovey stories that only fuel Yuka's anger. The boyfriend, however, remains kind and tolerant, treating Risa with genuine care.

Everything changes when Yuka unexpectedly witnesses Risa in an intimate, sloppy, and utterly shameless state with her boyfriend—far removed from her usual modest demeanor. The shocking scene of Risa eagerly pleasuring him and losing herself in ecstasy leaves Yuka furious yet strangely aroused, her body heating up with uncontrollable desire.

Haunted by the image, Yuka finds herself alone with the exhausted boyfriend during a convenient rainstorm shelter moment. Overwhelmed by lingering arousal and forbidden curiosity, the atmosphere shifts irresistibly. Yuka, inexperienced and curious about such feelings, gives in to the temptation, leading to her intense first-time loss of virginity in a passionate, backstabbing encounter. The episode builds heavy tension through jealousy, betrayal, and awakening lust, delivering explicit scenes of oral, penetration, and creampie with emotional depth.
