Developer's description

Dreadful monsters were stirring in the cave where Udonge had fallen into. Low-class monsters starving for females creep up, one after another. Can she escape the violence of sexual desire, or will she be trapped and have everything destroyed by sheer pleasure and humiliation? This is a derivative work, a fan work of Touhou Project.​
