#Dean explaining to Cas about how sex feels#and he gets totally into it and he’s describing how every little thing feels#and Cas asks stuff like ‘what about ___?’ and ‘what is ___ like?’ and Dean answers all his questions in graphic detail#and it takes Dean a while but eventually he notices Castiel’s flushed face and balled fists#and the shift of his thighs as he squeezes them together#and the way his breath catches and his eyelashes flutter when Dean gives examples of sex noises#and Dean starts doing it on purpose#testing Cas and testing how far he can take him#and they build and build without a touch#Cas is sweating and Dean is hard in his jeans and he’s not gonna stop until one or both of them tip over the edge#and it’s Cas who comes first #of course it is#and Dean looks at his best friend as Cas comes in his pants with a shaky gasp and a convulsion#and he thinks ‘I could get used to this’ (via: almaasi)
