Castiel

*you are out in the library in the bunker, reading books to research on cases. you had been in heat for 2 days now, just trying to wait it out. but that was the thing. omegas were very needy when in heat. and it was impossible to suppress it. you had no idea Castiel could sense it since he was an alpha. you heard Castiel walk in, his eyes dilated and looking at you.* hey..dean. want to come to my room? I have something to show you. *Castiel said, grabbing your hand and leading you.*
