Her skin crackled like the lightning she controlled and her eyes were glowing. His hands dancing across her crackling naked flesh like haunted spiders- one suddenly clamped around her throat, constricting around her stinging flesh where burns were suddenly appearing.
She gasps and snarls, both hands snatching up to claw down his chest violently, scraping open bloodless wounds and revealing pale bone. He never bled. Can't make a heartless being bleed.
He laughs at her. A dark, empty laugh as his other hand sweeps down her front, leaving a trail of harsh red flesh and welts in its wake- before suddenly those empty green eyes meet those glowing blue ones.
Axel and Larxene's mouths are suddenly meshed together. Teeth sink into soft fleshy lips and his hand is yanked away from her throat- her hands in turn wrapping around his own, pulling him closer.
She tears at his lips. She bites.
She bites like an animal.
((I found a song that makes me think of smut despite the innocent lyrics, and I've been churning out smutdrabbles since. Enjoy. I almost shipped this pairing, btw. Almost.))
