Untested Waters

Still, Prince Bronimir's blood coursed along his veins as though it were on fire. They had exchanged only a handful of exchanges and he was already breathing heavy, hot. Lord Viorel seemed to be reacting the same way. The pupils of his eyes were needle thin, the stormy gray irises fading to a lustrous indigo. They tracked Prince Bronimir’s every movement, fierce, penetrating. Inescapable. Their gaze drove Prince Bronimir to move faster, hit harder. To put on a good display. He wasn't sure if it was a trick of the light, the soft lanterns and the harsh, ever-moving wind, but Lord Viorel’s patches of scales seemed to have spread as well.

What he knew wasn't any illusion was the hard line of Lord Viorel's mouth peeling back to reveal two long fangs. White and curved.

Prince Bronimir had seen his fair share of fangs; bared in a snarl or snapping at him, attempting to swallow him whole or at the very least take an arm. They were simply a hazard of the job.

So he rationalized that's why his eyes were drawn to them, watching how the tips pushed into Lord Viorel's full lips, dimpling the skin but not breaking it, the wild light of the wind dancing on the wet surface. Until Lord Viorel curled his lips higher, revealing more, a hiss passing between them as his weapon failed to hit the mark again, his gaze frustrated and hungry like a predator. The sight sent a jolt up Prince Bronimir's body, his hands trembling with it, originating from a very unlikely source

In a place where humans and demons coexist, Prince Bronimir is invited to dinner as thanks for rescuing a snake demon lord's wife. Prince and lord drink, spar, tumble into bed together. Less simple than it sounds with snake anatomy and a bit of drug-induced mating.

Untested Water is a 7k story of snake demon/human featuring an open marriage, drugged sex (so some dubious consent), oviposition, and a brief bit of demon f/f.
