Vampire Kiss
The vampire kiss is a deep kiss on someone's neck that can involve sucking or light biting on the skin. Since some people find it painful rather than sexy, and since the sucking might leave a hickey, always ask permission before you give someone a vampire kiss.

Kurogane is not pleased. This surprises no one, as he rarely is in a particularly happy mood. It's difficult to breathe with his armor covering his mouth and neck, but it's better than having to deal with the kids asking where the mark on his throat came from.

Damn mage has an oral fixation.

I'm gonna wring his neck.

Calling the mark a bug bite can't really suffice in this situation, not when said bug bite has two small pricks and a large, red, painless bruise covering the tanned skin. No insect leaves a mark like that, unless the insect has two legs, blond hair, and a pair of vampire fangs.

Fai finds Kurogane as the ninja is sulking in the hallway wearing full armor as if he's going into battle. The children know better than to question it, and Fai knows he is the cause of it.

It's not a rough night, per say. But it isn't gentle either. Neither man is hesitant about where he leaves nail scratches and bruises, the heat and pleasure worth any amount of pain caused.

Fai is careful to keep his fangs tucked safely behind his lips while his mouth is on the more sensitive body parts, but as he sucks on the skin of Kurogane's collarbone as the other man's hands play over his pale skin, tongue swiveling, he forgets himself in the moment and bites.

The response is automatic. Kurogane sits up quickly and Fai jerks away, eyes wide. "S-sorry," he mumbles over the sweet blood on his tongue. Kurogane isn't always concerned about him biting; at times, he even welcomes it. But this world is a warm one, far too warm for armor or even a scarf. As Fai gazes at the mark he left, blood running in twin trails down Kurogane's chest, he cringes, knowing full well such a mark couldn't be hidden by anything else.

"I did apologize you know," Fai comments, staring down at Kurogane. The black haired man simply shoots him a glare, and Fai kneels before him with a sigh. He tugs the armor off of Kurogane's face and shakes his head. "You don't have to be so moody, Kuro-puu." He pulls a bandage from his pocket and sticks it over the hickey and bite on Kurogane's neck. "There, all better. Just say you fell." He rises and returns the way he came, and Kurogane watches him go.

Well. Maybe I won't wring his neck.

He still has an oral fixation though.
