A university student tries to order a call girl, but a real incubus (♂) shows up at his door instead! "Heh, you're more of a bottom than a woman." teases the incubus. The student makes a pact with the incubus... but it would seem that the dominant demon has a cute side, and soon finds himself on the backfoot...! Featuring a [Straight male university student] x [Top Exclusive Incubus] coupling with a GEKOKUJOU (inferior supplanting the superior) scenario.
