This Is but a Hell of a Dream manga features story and art by Senco Yoshimoto.

Despite being an incubus, Forni is not good at sexual matters. Unfortunately, an incubus needs sex to survive… so he ends up passing out in the street due to starvation. Luckily for him, he gets rescued by the host club worker Harumi, who takes him home. That night, Forni sneaks into Harumi's dream to have a “meal” — but it's his first time and he doesn't know how to do it! That's how Harumi ends up teaching him instead…

“When it feels good, say it, okay?”
