okay, well if we really wanna get down to it:
cas loves, loves, loves getting eaten out by dean. he loves the noises dean makes when he pushes his tongue deeper inside him. loves how sloppy it is. wet and messy and loud,Ā because dean gets so into it he sometimes forgets how to breathe before resurfacing and gasping for air. heās so impatient, too. tries to go slow in the beginning, wants to tease cas, just breathe light kisses where cas is needy and waiting, but gets so turned on he licks deeper and harder into him in no time at all. he loves how dean grabs casā thick thighs, spreads his cheeks as he moans into casā hole. loves how he can feel dean growing desperate to hear cas make just as much noise as he does.
cas makes a lot of noise. he always does and dean knows. most of the time it starts out as muffled whimpers into the pillow, burying his face in it until he canāt take it anymore, until dean gets vocal and tells cas how perfect he is for him all spread out, until deanās hands wander and land on his hips, his back, one hand on his neck grounding him, squeezing softly as he kisses the dimples on casā lower back.
thatās when cas lets out a downright filthy groan and flips himself around, dislodging dean for just a precious second, setting his feet on the mattress and looking at dean with so much adoration and love, face red and sweaty. disbelieving every single time they do this. how this is such raw and intimate act, how the only person heād ever be comfortable with doing this, is dean. how dean gazes right back, how it should look obscene and dirty from where heās kneeling between casā spread legs, but doesnāt. how dean knows exactly what cas needs in these moments, how he knows cas needs his hands in deanās, holding on tight as dean goes back to work.
cas loves how dean can tell when heās getting close, just from his tongue inside him, when he tenses up, starts whispering and begging. when dean tells cas to run his long fingers through deanās hair so dean can finally wrap a hand around his own cock and stroke in time as he gently pushes one finger inside cas, still licking and kissing around his hole, never stopping. how he finds his sweet spot so easily, rubbing slowly but relentlessly, just the way cas loves it the most. how deanās urgent, low groan as he comes messily all over their comforter and casā thigh is the thing that finally drives him over the edge. how they stay like that for a minute or two. but get clingy the moment the aftershocks settle, dean crawling up casā body to share a filthy, long kiss before they both settle, too lazy and happy to clean up. cas loves how they both fall asleep next to each other, touching everywhere and how he knows he gets to have this intimacy and trust and pleasure with dean for years and years to come.
