The Realm of Shadows: The Rivers of Hell 1.5

"What's that?"
"Your leash and collar. Pet."

For thousands of years, the succubus Naamah did who she wanted, when she wanted. As a lust demon, she was no stranger to using her wiles to achieve her goals. So when her uncle, the archdemon Ashtaroth, asked her to seduce and distract a young Cambion, she took on the mission with horns gleaming and tail swinging. Yet, she finds the mortal far more intriguing than she anticipated. Especially since the boy refuses to admit he's most comfortable under his Mistress' boot.
Kevin grew up on the streets, used to ignoring his needs and focusing solely on survival. Abducted into Hell and trained to face its dangers, he thought he was doing pretty well... until he met a curly-haired succubus who liked to stick her tail where it didn't belong. Now, he's got all these new desires he's not used to denying - each centered around the bossy wench.
After being forced to spend a few months together, with Naamah holding Kevin's leash, they are finally free to go their separate ways and return to life as it was before their fateful tumble. After all, that's what they both wanted. Or is it?
