Manami is forced to spend the night with her lesbian senior, Yui, while on a business trip, leaving her filled with anxiety—and her fears soon become reality. Once alone, Yui leads Manami to the bed and forcefully initiates a lesbian rape. Though Yui's advances are aggressive, they're interwoven with tender yet lewd caresses, escalating into passionate acts that engulf Manami's entire body in kisses. In particular, the intense cunnilingus—both clitoral and internal—conveys Yui's serious desire, gradually reaching Manami's heart. Their relationship deepens over time, emotions synchronizing until, even before heading to work, they indulge in loving, intense lesbian sex while Manami is still in her business suit.
