Disclaimer: And still, not mine. And still, so sad.
This one and "Squirm" are two of my favorites for some reason. I just like the way they played out.
Build Up
He's not sure when he first noticed it. He's pretty sure it was when Reid moaned and then clapped a hand over his mouth. Then again, they were in a motel with thin walls and Reid probably didn't want Hotch or Rossi to hear him.
But he made sure to pay attention the next time they were truly alone, back home in their shared bed.
It would start quietly, with pants and whispers as he trailed down the pale body, teasing with touches and kisses. A soft kiss on the neck would draw a soft "Oh!" from bitten lips and hands stroking his abdomen would make him press his head into the pillow and pant.
It built from there; the exclamations of "Oh!" would get a little louder and the pants would turn to whimpers. Whimpers could be coaxed out of the genius by sucking on his earlobes or playing with his nipples.
From there, it was like a game to find the right triggers. Whimpers would turn to moans if a hot tongue was dragged down Reid's abs and stopping just above his waistband, usually moans of frustration. The noise would take a slight downward turn then, as he fiddled with the button and fly of Reid's pants, because the genius had to be distracted before his pants could be removed.
The noise could quickly build again once the pants were tossed aside. A warm hand circling a hot cock was rewarded with a loud "OH!" and Reid's hips would arch off the bed too. Stroking the genius first brought more pants and whimpers that became moans of pleasure as he drew closer to release.
But it was the grand finale that he looked forward to. Didn't matter how, hands, mouth or penetration, but when Reid was really close, that pretty mouth dropped open and everything poured out.
It usually started with another "Oh!" (it seemed to be the only syllable the genius could get out during sex) or a long, loud moan that he was sure that the neighbors could hear. After that, what little filter that Reid had between his brain and his mouth evaporated.
"Oh! OH! Damn! Feels go-od! Please, please, more… Harder, please, harder… Right! The-re. YES! Oh, fuck (And the swear was one of his favorites) yes! H-arder! Please, oh, please!" Over and over until Reid came his brain out and the process reversed itself, back to soft whimpers and pants.
And when everything was over and they were cleaned up and curled up in bed, his arm draped around Reid's waist to pull the genius close. As they settled in to sleep, Reid would sigh and squeeze the arm around him. And his favorite sound would slip out.
"Love you, Derek."
