Meanwhile, the mercenaries.

Two naked men stumbled along the roadside. It was getting dark, and raining, and they were beginning to turn blue with cold.

“You couldn’t keep it in your pants, could you?” one snarled. “You had to go for that redhead.”

“Bastard!” the other shouted. “You know damn well if I hadn’t been first, you’d have been all over her! And you wouldn’t have been complaining if things had gone well.”

“Of course not! If things had gone well, I’d be sitting in a nice warm room right now with my cock up that slut’s arse! If that crazy bitch hadn’t interfered–”

“Hey, boys.” The two men paused to stare at the vision that had just spoken. She leaned against a tree protected from the rain by its foliage. She was stunningly beautiful and completely naked, unconcerned with the cold. The mercenaries’ eyes drifted over her pale skin, her full, pink-nippled breasts and hairless pussy – but they couldn’t help but notice the horns at her brow and the tail that lashed behind her.

“D-d-demon!” one gasped.

The succubus sighed. “Sure I am. But my cunny is just like a humans. Only better.” She spread it, parting the lips with her fingers so they could see its pink depths. “Want to give it a go.”

There was a pause. “What the hell,” one of the men said. “Not like we couldn’t use it. And not like we have much left to lose.”

Before his companion could reply, he stepped forward and pushed the demon roughly to the ground. She grinned wickedly as he thrust into her, and rolled him over so she was on top. His companion was about to object, but then the demon lifted behind her and spread her buttocks, temptingly displaying her arsehole. All his reservations were washed away by the desire to fuck her arse.

As the two men sandwiched her between them and brutally fucked her, the demon smiled. “That ‘bitch’ you were talking about earlier. She wouldn’t happen to be a skinny whore with light brown hair.”

“Huh?” Both mercenaries struggled to think through the sublime pleasure they were feeling. “Sound like it. She screwed us over.”

“It sounds like the girl my mistress bound me to search for. I bet you’d like **** on her?”

“Fucking right!”

The succubus’s grin widened. “Done.”

Raw demonic power flowed through her well-fucked holes into the men’s bodies, changing them.

The pair that had once been man roared in triumphant unison, and she moaned as they pounded her harder and faster with their demonically enhanced cocks.
