Scum Carnage

In a world where guides have no human rights, the only being Shio must protect is his younger brother, Ter. Having struggled to escape the fate of being a ‘selected one’—little better than an Esper sex slave—Shio heads to the Esper house, a place akin to hell, when his brother becomes selected. “Who left their guide behind?” But unluckily, Sio encounters Esper, Erutio, before his brother. Sio tries to escape him, but... “Coming here smelling like this? You want me to eat you, don't you?” “I, I came to find my brother...!” “Then crawl nicely. Beg for your brother's life with your guiding.” The arrogant Erutio violates Shio without restraint, cruelly holding him captive. Time passes, and Shio grows accustomed to this life. Days flow by neither happy nor unhappy, but Erutio seems oddly off. “Tell me about yourself.” Suddenly trying to have a conversation? “I want to kiss you.” After starting with sex, now demanding a kiss? How on earth am I supposed to appease this utterly capricious Esper?(Source: Lezhin, translated) Note: Include three extra chapters.
