Castiel notices it. The way Dean bounces on his cock, like he's very tired. In a way like he doesn't want to take control anymore but still forces his body to.
Dean doesn't want to be vulnerable and limp during sex. The Hunter is very shy about giving up control, he wants to repay Castiel with this. But he can barely take it anymore.
"Dean." Castiel whispered. Snapping Dean out of his sex hazed mind.
"Hm?" Dean hummed. Trying to grind his ass at Castiel's cock, searching for his prostate. He's barely bouncing anymore.
"Let me take care of you.." The angel whispered.
And Dean finally collapsed onto Castiel's chest with a soft thump. Castiel reversed them over. His hand gripping Dean's hair to hold him in place.
"You're so pretty, Dean. I'm so in love with you." Castiel kissed the corner of Dean's lips, then pressed their lips together. It was slow and affectionate. And Dean was practically melting into it.
Castiel gently pulled back, then pushed in.
By the look on Dean's face it was clear that he's very sleepy and tired.
Castiel smiled. Kissing Dean's lips again.
Dean gave Castiel a faint smile. The small gesture made Castiel's heart flutter.
"Do you want to sleep, my love?"
Dean shook his head. "Use your words, baby."
"No.. I want to—want to cum.."
Castiel smiled. He then thrusts his hips torward Dean suddenly. Making the Hunter gasp in surprise. He repeated that motion over again. Until Dean is a squirming mess beneath him.
Dean's trying to shove Cas away from him. Tears falling freely from his eyes.
But Cas held tight on Dean. Kissing the Hunter's collar bones softly.
"Cas.." Dean moaned. His walls clenching hard against Castiel's cock. Making the angel whimper.
"Cass.. Jesus Christ.." Dean gasped as
Castie latched onto Dean's nipple. Sucking like a damn starving baby.
"Cas– Cas.. Oh God." Dean opened his eyes. Trying to look at Cas but his vision was starting to blur.
"I–I'm gonna come.." Dean moaned. His eyes fluttering shut. The bed groaned beneath them. Dean lost track of time to say the least. He doesn't even remember what day it is in his state.
Castiel sped up his pace. Ramming onto Dean's abused hole with such brutal force it made the Hunter cry out his name.
"Oh, Dean.." Castiel whispered. Kissing and biting onto Dean's lower jaw.
"Come for me, my love.."
Dean couldn't take it anymore. His cock coating watery semen onto both their stomachs. Dean cried out. And he could feel Castiel's warm semen painting his gut. He really, fucking saw stars. It was the best feeling he ever had. Before his fucking body suddenly went limp under Cas. And his vision blacked out.
Maybe it was from exhaustion. Maybe it was from overstimulation, he doesn't know. But the momment Dean woke up. Castiel was beside him. Watching Dean sleep, like he does.
"Oh God.. What time is it, Sweetheart?" Dean asked, sitting up in panic.
"It's eleven pm." Castiel replied shortly.
"My love. You should get some sleep."
Castiel patted Dean's bare chest. Urging him to lie back down. Dean complied. He lied back down. Resting his head onto Cas's clothed chest. Wrapping an arm around Castiel. Then he went back to sleep shortly after.
Before Dean fell asleep. He remembered Cas whispering something in enochian. The Hunter could only translate one word. It was love.
