Love Slave (Inoue Kiyoshirou)

In this black-and-white hentai manga by Inoue Kiyoshirou, a captive teen named Shiraishi is subjected to severe physical, sexual, and psychological abuse by sadistic classmates and a duplicitous student counselor. Pushed beyond her limits, she dissociates into a delirious, submissive state, begging to be used as their slave. The tormentors continue degrading her, treating her like a human urinal and presenting earrings as a twisted symbol of her slave status.
