Incubi have long visited humans in their dreams and absorbed their libido. Lately, humans have taken to summoning incubi who would normally be unable to make the trip to the human world on their own. When successfully summoned, and incubus must collect libido from the human in question via bodily fluids.

Luka is one of the most popular incubi for this service. He has a heavy customer base because he looks similar to a popular idol. One day he doesn't check his newest client and finds himself at a man's home. Never successfully having taken on a male client before, how will Luka manage to get the bodily fluid he needs to get home?
