[Kiki] Slave Duty (Bishoujo Zecchou 48 Renpatsu) [Tenshi-Nyow]

Shimazu-san and Kasahara-kun are chosen for slave duty at their elite school—stripped bare, collared, and required to serve every classmate's needs without ever saying no. What begins as a cleaning task in morning homeroom spirals into quality-sampling sessions reported straight to the faculty, naked hallway parades between classrooms, and the petite girl servicing lines of boys while a busty teacher squeezes in on the staff-room action. Beneath the relentless group service, a genuine connection blooms between the two collared slaves, ending with her happily wiping him clean and hoping for more days alone together.
