Our hard-working office worker heroine is feeling raunchy. She picks up her phone, and heads to the "Rental Incubus" website... Normally, because of the cost, she sticks with the basic course, but... it's a little too vanilla for her. The incubus who takes care of her isn't really into it either. However, it's her lucky day, and she's managed to bag the premium course for some reason! And so, Lelix, the very serious-looking handsome incubus appears in her home. The premium course goes a lot harder than the basic course, but what exactly does that entail...?!
