The backstory for my commission.
Kronya defeated Byleth and routed her students, but instead of finishing her off, she thought about degrading her into something befitting her; or at least into something Kronya would find amusing.
Dragging Byleth into the most raunchy and ghetto parts of the slums, she pimped her out to the gangs. After months being ravaged by the thugs, Byleth was nothing more but a husk not even remembering her name.
Kronya found it delightful seeing her ravaged and impregnated by dirty thugs whom were more than willing to pay such a cheap price for a cute girl. Thus in the image you have several of the thugs having her way with Byleth as Kronya masturbates her self.
