Welcome to Yarimari Academy, a prestigious co-ed school where the student council president, the dominant and insatiable Rikka Inudo, has enacted a school-wide ordinance: mandatory, daily fucking for every student. When the unsuspecting male protagonist transfers in, he's immediately targeted by Rikka and her lewd enforcers. He's thrown into a world of non-stop debauchery, forced to participate in massive orgies in every corner of the campus. The series arc follows his initial shock turning into slutty submission as he's passed around between Rikka, her busty cohorts, and countless other horny schoolgirls. Watch him get his balls drained raw in classrooms, the nurse's office, and public hallways, his cock constantly servicing wet, greedy pussies and eager mouths. Each episode escalates the depravity, culminating in enormous group scenes where every hole is filled and every face is covered in cum, solidifying the academy's reputation as a temple of pure, unadulterated fucking.
