Fortuna in Somnium (Buffy the Vampire Slayer, Spike/Xander)

Sharp teeth bit deep into Xander’s neck, just above where his shoulder and neck met. He arched into Spikes touch and tilted his head back to give the vampire better access. That was when he realized that this was a dream. In real life, Spike didn’t touch him like this and he didn’t let vampires bite him, he didn’t like it when they did. He wasn’t complaining about it now.

The bite didn’t last long. It was a distraction, meant to keep him from tensing as Spike slid inside of him. The distraction worked. His bones felt like Jell-O. There was no pain as Spike entered him, seating himself in one long push. Xander moaned and wrapped himself tighter around Spike. He doubted anything short of an apocalypse would get him to let go of Spike.

It was strange having Spike inside of him. He didn’t make a habit of letting guys fuck him, let alone undead guys, though this was by no means his first time with another man. If his trip to Oxnard had taught him anything, it was that he was a definite fence-sitter, good with either gender. So, it wasn’t so much that Spike was fucking him that was weird, because, really, it felt damn good and he was pretty sure this was going to get saved in his memory banks as the best wet dream ever. No, the weird thing was how cool Spike felt at first, slightly chilled yet hard flesh that slid inexorably inside of him, growing warmer as the friction of Spike’s thrusts heated his skin.

Xander was moaning loudly, his breath hitching every time Spike slammed his hips forward. Spike was licking at his throat, right over the bite mark, like he was trying to lap up every last drop of blood on Xander’s skin. The vampire’s tongue felt incredible. It was slightly rough, very dexterous, and he suddenly needed it in his mouth like he needed oxygen. He turned his head to catch Spike’s lips. The vampire must have sensed what he wanted because suddenly Spike was all force. He pinned Xander’s hands above his head and thrust wildly into him. Xander screamed, the sound of it cut off by demanding lips. One of Spike’s fangs nicked the inside of Xander’s lips and they both moaned as Spike’s tongue frantically chased after the few drops that welled up.
