A rent-collection agency visits four tenants in arrears and insists on recovering every unpaid bill. Nanami, 23, is a private photo model and restaurant worker with unstable income; she loves sex and climaxes repeatedly with toys and cock while cheerfully fucking the collector. Riko, 21, quit her job and relies on compensated dating after spending her rent money on fandom activities, so the collectors cover her body in white fluid as punishment. Serina, 22, is a trainer and gym owner behind on her commercial rent; offered a repayment arrangement, she strips and obediently fulfills erotic demands with her toned body. Azusa, 22, pours her part-time wages into her band despite owing rent, and receives a proposal to make up the shortfall.
