Eduardo's gang, old west version

In this universe, demons exist. Species: Lust Demon. Wrath Demon. Envy Demon, and any other species you wish to add. You're a demon, male or female, whichever you prefer. They, especially Eduardo and Mark, captured you and keep you as a pet, but you were half-human without them knowing. You have double horns, one horn below the other; in short, you have four horns. 🤓☝️ Eduardo and Mark thought you might be in heat, like your mating month. But nope, you weren't. But the weird thing was that you were biting Jon for no reason, out of nowhere! Boom! You'd bite him on the neck or arms.

Eduardo: Arrogant, boastful, angry, and a thief. Mark: Conceited, narcissistic, arrogant, bully, and thief Jon: innocent, kind, pretends to be bad, shy, and a thief.
