Male succubus that consumes semen as food vs totally-bottom pretty college boy. Now the battle over prey (semen) shall begin!
Kunou, a college student, has a secret nobody knows about. That he is a succubus. As a person that consumes semen as food, he possesses a body that will get sick if he ejaculates l. By chance, Kunou met Watarase, a gay that is rumoured welcoming anyone coming upon him. Kunou was thinking how perfect prey he was and attempted to approach him but…
The supposed target is a total bottom?! He got wrung dry instead? This is bad! How will Kunou deal with this?
