Dean didn't feel different, at first. Castiel laid back against the door, his elbows perched and legs loose. Castiel kissed Dean back with the same fiery urgency at first but then he placed his hand on Dean's neck and slowly licked Dean's mouth. The sounds Castiel made were soft and cooing, like he was stilling a wild creature. Dean burrowed his hands into Castiel's trenchcoat, caressing the warm silky lining, unbuttoning and unzipping with more control and finesse than he thought himself capable of. Castiel's body was hard, firm flesh and heated skin beneath folds and folds of fabric. Dean zoned out on the soft cotton and slippery synthetics for a moment. Castiel was all come hither stretches and lowered lashes, inviting and devastating at once. He took Dean's hand and guided it where he wanted it, encouraging as Dean fumbled with silky skin and velvety weight.
"What if I shift?" Dean asked.
"We'll deal with it if you do," Castiel answered, panting, shoving Dean's hand down his pants recklessly.
"Don't wanna pass out on you," Dean added.
"I can have that effect sometimes," Castiel boasted. "It's only natural."
"Shut up, Cas," Dean nipped at Castiel's ear. "I'm not kidding. I haven't, haven't done it like a fish before."
Castiel's gills opened as his body shuddered.
"Quit laughing."
"Dean, just go with the flow okay."
"Did you just ..."
"I'm sure you are more than capable of copulation in the Impala," Castiel sat up, his cheeks pink. "Not to rush you but we're kind of on a schedule."
Dean pouted. "Maybe I was just savouring the moment ..."
"Maybe you need me to drag you to the backseat and pound you."
"So help me Cas if that was another wave pun," Dean blushed, his eyes darting to the tail end of the car wistfully.
Castiel popped open the door and for a split second Dean thought maybe he was leaving. Then the driver's side door shot open and true to his word, Castiel was pulling him out by the collar. They tussled for a moment, the air outside was cold and Castiel growled at Dean while Dean's hand slipped on the back door handle, scrabbling in his urgency. He prayed he wasn't clawed out or anything, not wanting to scratch up the car. It was too dark to tell and frankly Dean wasn't really aware of anything except the persistent and steady shoving Castiel was doing behind him. Castiel had Dean pinned flat on his back. His fingertips pushing firmly into Dean's throat.
"Just you and me Dean," Castiel's nail was blunt where it flicked over Dean's pulse point. "Show me what you got."
Dean gasped, his chest puffing up, his legs stiffening. "Am I gilling out?"
"No," Castiel said, his eyes dark. "Not yet."
Dean grabbed onto Castiel, a hand over a shoulder blade, another on the upper back thigh. The hold felt desperate and feeble even to Dean. Castiel pressed down, intoxicatingly heavy, making Dean groan at the weight of him.
"Claws?" Dean asked.
"Uh-uh," Castiel tilted his head.
"Maybe if you ..."
Castiel cut Dean off with a push of his hips. "I know what I'm doing Dean."
"I'll just relax then," Dean murmured.
Castiel twisted his hand between them, a small flick of his wrist had Dean give out a shuddering moan, his eyes suddenly wide.
"The excretion is normal, copious though it might seem," Castiel said calmly, his forearm flexing.
