On the couch

For all Sam Wilson knew, Steve and Bucky had been watching some TV show in the living room on their floor of Avengers' Tower. Evidently, the show hadn't been very interesting.

Steve Rogers lay on his back, shouldered up against the backrest and fast asleep along the length of the couch. Bucky Barnes was on his stomach, against Steve's side, and almost falling off the edge of the couch, using Steve's arm as a pillow.

One of the two was snoring, and after watching for some time Sam figured out that it was Bucky.

Whatever show they'd been watching was long over. The TV droned on behind him, probably offering white noise for the two slumbering ones.

Sam fought his compulsion to turn off the TV and left the room. He later returned with Natasha.

They both took up similar stances, watching silently as the super-soldiers slept on the couch. Then Natasha pulled out her phone.

Natasha took a picture of Steve and Bucky and sent a Snapchat to Clint with the caption, "lethal puppies".

Sam had no idea how he'd had enough self-control to refrain from laughing this whole time.

"This happen often?" asked Natasha at a whisper.

"Oh yeah," Sam whispered back.

Natasha snapped more pictures.

One of the two on the couch gave a slight moan in his sleep. Natasha and Sam both tensed, ready to run away if it became necessary.

Inhaling deeply, Bucky rolled over away from the edge and curled up on Steve's side. Slightly wakened by the disturbance, Steve shook his head, his eyebrows creasing as he swiped numbly at his face.

Sam did not know how in the world he wasn't laughing.

Finally, Steve's arm made contact with the side of Bucky's head, and he rolled slightly, letting that arm fall limp over Bucky's shoulder.

After a moment of quiet, Bucky snored—loudly—into Steve's shirt.

Sam couldn't take it anymore. He clamped both arms around his sides, wheezing from trying to hold back his laughter.

Natasha wore a rare, wide grin. "Thanks, Wilson," she murmured as she snapped more pictures. "I owe you for this one."

Sam was there when Clint checked his Snapchat, and the archer almost died of suffocation from laughter.

A/N: I figured I'd do something different, just for fun, because we need it after the trauma of Endgame. This will probably be a weekly series, updating on Saturdays.

I've got a list of prompts I want to write, but I always need more! Leave a sleep-cute request in a review (characters, time/place, situation, etc.) and yours might be the topic of the next drabble.

Reviews are puppies.
