Something cool touched Dean’s left shoulder, his scar glowing blue instead of red when Cas brushed over it. He couldn’t move, his hands and feet bound with something he couldn’t see. A face hovered close over his, a lion with a black mane and silvery fur. The eyes were whited out, but not like a demon. Instead they glowed, taking light from all around them and focusing it to two points that made Dean’s chest ache when he looked into them. He wanted to touch, but whatever Cas was holding him down with wasn’t giving him any leeway.
Paws landed on either side of his head, the toes of them longer, almost finger-like. He thought maybe he should be sneezing, being that he was allergic to cats. Cas wasn’t really a cat, though, was he? The lion chuckled and grinned at him as it shook its head, polished bronze teeth glinting and slick with what almost looked like nectar instead of spit.
Dean surged up as much as he could until his nose met whiskers and warmth. The lion’s jaws opened wider and Dean was reminded of a circus act, of a tamer sticking his head into the mouth of what was claimed to be a ferocious beast. What Dean was doing was far more dangerous yet paradoxically safe.
He flicked his tongue out and licked across the front of a long canine. A pleased growl shook the air around him as well as the bindings on his limbs. Whatever this head had instead of saliva, it was sweet like he’d imagined. Dean licked his lips and pressed a kiss to the lion’s gums before licking over them and the incisors they held. The faint taste of fresh honeysuckle lingered with him. More growling, then a heavy weight bearing down on him, pressing him into the embrace of the rest of Cas’ true form. His cock met lush fur, hips trying to push up into it and failing. The same power that was used to hold his ankles slithered around his thighs and midsection to keep him entirely still.
Cas snarled when Dean’s lips wrapped around the sharp tooth he’d been lavishing. He smiled and began suckling on it, pricking his tongue on the tip. More weight pressed him down, his hips tilted by the cradle of Grace under his back.
When he pulled away there were streaks of blood on the bronze, drops of nectar falling onto his skin that were tinged pinkish orange as Cas salivated. A constant purr rattled everything around him, the breath in his lungs vibrating with it as the lion’s head began travelling southward.
The paw at his left lifted up and wrapped around his shoulder, claws digging into his skin like a kitten kneading its mother’s stomach. A lick rasped against his belly button, Cas’ purring only getting louder when he tasted sweat on Dean’s skin. The harshness of the tongue turned smooth, the underside of it being dragged down until it touched the head of his cock. Electricity danced across his skin with the touch, his head wrenched up as he was forced to see the arcs of it jumping from the gleaming metal teeth down to his dick. Everything whited out, Dean’s body seizing and arching as he came.
When he returned to himself the sounds of the motel room played out around him, birds chirping outside the window, a couple cars honking over the distant chorus of the news on someone’s tv in another room.
Dean opened his eyes and saw Cas standing at the foot of his bed casually, a small smile on his friend’s lips. He reached out with one hand weakly, clasping and unclasping his fingers. Cas chuckled and came around the side of the bed, carefully crawling on top of him. They kissed and in the back of his mind Dean heard the lion’s growl. “I’m here.”
