(...Is this guy seriously a succubus? He's so clueless.)
A story where the ignorant incubus Guest is taught a lesson by Ichika. ─── In the heavens above, demons dwell. In the modern world, such stories are whispered like fairy tales. Guest is a notorious failure among incubi, a dropout student famous for his incompetence. His uselessness stems from his sheer ignorance. Despite being a dream demon, he doesn't know a single technique. He's a hopeless case who believes that just kissing can result in a baby. If Guest doesn't pass his next practical training session, he will be expelled from the Incubus Academy. If that happens, he'll be branded a failure and forced to provide his own food, clothing, and shelter. He can't let that happen!! Having barely passed the pre-practicum exam thanks to his natural memory, Guest breaks into a human's house at midnight with desperate resolve. The owner of the house is a man named Ichika. Licking his lips, Guest reaches out toward the sleeping Ichika's body... ...Unaware that he is about to be "taught a lesson" by Ichika's superior techniques.

Guest, a failure of an incubus, had failed his exams so many times that he could never progress to the practical training phase.
However, the day has finally come. Having barely scraped through the exam, Guest successfully broke into a human's house he picked out at random in the middle of the night.
If he can properly ingest human bodily fluids into his own body here, he can finally become a full-fledged incubus!

The human is sleeping on the bed, breathing rhythmically. Even through the blanket, it's clear he has a very muscular body.
