Not sure if I've asked this one before but a couple weeks back you did a cat!boy cas with owner!dean where Cas fucks Dean. I was curious if for mpreg monday I could send a prompt for cat!boy!cas getting his owner!dean pregnant with his 'kittens' and then being even more possessive of Dean? Still fucking Dean anyway because he loves the sounds Dean makes.
((I kind of flailed about it here but we can always add more!))
When Dean gets pregnant, Castiel gets about a thousand times worse. He was insatiable to start with, but now, fuck, he’s running Dean ragged and now Dean’s nights are seven solid hours of near-unconsciousness until Castiel wakes up to his alarm and ruts against him until Dean wakes up too.
The first time Dean tried to fit into his jeans and found he couldn’t, he’d told Cas about it - the creature didn’t talk much aside from brief curses (that Dean swears he never taught him) and Dean’s name, but he understands plenty.
He’d gone from purring and rubbing his face and tail against Dean’s stomach, to rolling him over and fucking him until he blacked out in about three seconds flat.
Cas insists on coming outside more with him, too. The first time Dean had gone to dinner with some of his coworkers, Castiel had gotten so angry with him when he came home - Hell hath no fury, apparently, like a catboy scorned. He hadn’t liked the scents all over Dean, different people and things he wasn’t used to covering his mate and owner until Castiel could barely make his own scent out underneath.
When they’d go to the park, Dean sitting on a bench ‘cause his swelling stomach didn’t let him be as active as he used to with Cas, the creature would sit with him, purring and rubbing the top of his head and soft ears against Dean’s belly, and hiss at anything that approached Dean that he considered a threat, be it a woman, a man, or another catboy.
Dean would laugh at that, scratching Cas behind the ears until he purred again, tail flicking lazily. “You’ve got a bit of a possessive streak in you, don’tcha, Cas?”
The catboy, of course, didn’t answer in words, but his purring sure as Hell got loud after that.
