The series revolves around the insatiable lust triangle between Kirika, the stern student council president, Yuma, her devoted admirer, and Kyouka, a promiscuous transfer student. Initially, Yuma fantasizes about Kirika, but Kyouka's arrival ignites a torrent of lesbian debauchery. Kyouka wastes no time seducing Kirika, engaging in a passionate, sloppy session of cunnilingus that leaves them both trembling and drenched in each other's juices. Yuma stumbles upon their tryst and, instead of being shocked, is overcome with arousal. She is quickly pulled into their activities, forming a voracious threesome. The rest of the series showcases their relentless sexual exploits; they engage in intense scissoring, deep-throating dildos together, and orgasmic threesomes all over the school, from the student council room to the empty classrooms. Their moans echo as they lick, suck, and finger each other to climax, constantly exploring the depths of their shared carnal desires in a non-stop, cum-drenched yuri fantasy.
