"Stark?" Cap called down into the lab. "You need to sleep," He continued. "It's like-" He had stopped mid-sentence only to see Tony asleep at his workbench. "What am I going to do with you, Tony?" He sighed to himself; the man looked rather peaceful in his sleep. Scooping up the man Steve made soft cooing sounds as if to mock him.
"Come on, Stark. It's time for bed." Steve said in almost a whisper. He had taken just two steps up the stairs when he heard a mumble come from the man in his arms, followed but a struggle. "Cap?"
"Mh? How can I help you?" He smiled softly at the man in his arms.
"You could put me down." The man smirked at his own comeback. A quiet grunt escaped his mouth as Steve dropped him on the bed. Steve crawled over the man and wrapped himself up in the blankets. "What are you doing, Cap?" Tony looked at the older man in confusion.
"You need sleep." Steve slipped an arm around Tony and pulled him down, giving a yelp his head landed on the pillow with a thump. Tony pushed his jeans off and onto the floor nuzzling into Steve's chest.
"Why did you want me to come to bed, Steve?" Tony began to say. "It's not like you can't sleep alone."
"I was cold." Steve blushed a pale pink and readjusted his position to face Tony.
"You're a liar." Tony smirked up and the man and placed a soft kiss on his lips before settling back down into Steve's chest and falling into a light sleep.
