How to Raise a Top-Tier Incubus

I don't lack money. I lack love. So I bought a top-tier incubus from a five-star incubus service.

Customer service told me:

[Dear, this top-tier incubus of ours needs your loving caresses. Please treat him well~]

Caresses, huh? I'm an expert.

If he gives me love, I can caress him until he rubs himself raw.

But nobody told me this top-tier incubus would change colors!

And why is his throat always making noises?

The Incubus Care Manual never said anything about that!

The master is a 200-year-old professor who knows absolutely nothing!

The little incubus is a shy, innocent 100-year-old child~
