How to Raise a Top Succubus

I was not short of money, but I was short of love, so I bought a top-quality succubus from a five-star succubus service store. Customer service told me: [Dear, this top-notch succubus in our family needs a loving caress, please treat him well~] Caressing, huh, I'm the best at it. As long as he gives me love, I can caress his bald skin. However, no one told me that this top succubus can change color! Also, why does his throat keep ringing? It's not mentioned in the "Succubus Breeding Manual"! The master is a two-hundred-year-old professor who knows nothing! Xiaomei is a shy succubus and a very innocent hundred-year-old child~ ps: first person, GB text pps: I made up all the professional terms in it. Concept: Chameleon also loves
