[Sei no Mamono (Sema)] Gloomy Succubus ~glory hole connected to another dimension~ [Penguin Piper]

A timid schoolgirl hiding monstrous urges gets her chance when a hole in the wall turns out to connect to another dimension, and her dormant succubus blood erupts free with horns, wings, and a whipping tail. What should be easy hunting turns into a war of nerves when the massive member waiting on the other side radiates evil-repelling energy and belongs to a monk who is definitely not a normal man. Watch a gloomy wallflower declare herself the predator instead of prey, fangs bared and pride on the line in a one-on-one duel of stamina she refuses to lose.
