Reiki is your run-of-the-mill company employee. Little does he know, his high-quality body fluids are exactly what incubi want. Incubus King Klesis, considered the strongest among his kind, takes a liking to Reiki and kidnaps him. Even with his body restrained, his freedom snatched away, and his heart violently fighting against his captor, Reiki’s body gradually begins to accept the pleasure in his pain… A messy inhuman fantasy between a beautiful, narcissistic, sadistic incubus and a strong-willed tsundere human with the worst luck.
