Trixie just needed pointers on a naughty little spell she was having trouble with--so naturally she summoned a succubus to help out. But Trixie's summoning know-how wasn't exactly up to snuff, and what she called up was less pony succubus and more furry hellhound named Loona.
Not that she's giving up on getting some help with that spell, though.

Contains futa and furries!

A crossover with Helluva Boss and an offering for Dirty Little Secret's Furry Foray Festival.
