Steve felt like he was in another world of pure ecstasy, every part of him was humming. He couldn't stop staring at Tony's glistening back, muscles flexed, sweat dripping. Tony's whole being moving in sync with his. Steve groaned louder and thrusted faster as his ecstasy approached climax. He felt himself explode inside of Tony and he cursed with pleasure. Tony groaned loudly and his body shook as he too reached finality.
Tony turned around and leaned back against the wall with an elated grin on his face. Steve kissed him on the chest and then his lips.
Tony gave him a gentle knuckle-sandwich on the chin. "Damn, you are…" He scanned the ceiling as if trying to find the right words.
"I'm what?" Steve asked, smiling.
He shook his head. "No words. Just no words."
Steve hugged him and buried his head on the man's warm and sticky chest. He had never felt like this with anyone before. He wanted to hold him all night.
"That was my first time you know," Tony said.
"Huh?"
"On the receiving end I mean. It was very…I am just very surprised it felt that good. I had no idea."
"I could say the same thing."
There came a knock at the lab door and the pair jumped from the wall.
"Hey, Tony. You in there?" It was Natasha's voice.
In a panic, Tony and Steve quickly looked around for their clothes. Neither dared to respond.
"I heard groans. Did one of your wild experiments turn loose on you again?"
"Uh, nope! Everything's pitch perfect," Tony yelled.
Steve only had his sushi underwear. "Where are my clothes, Tony?!"
Tony paused in thought. "Well seeing as how your uniform was torn to shreds from the battle…" He seemed to be thinking about it for far too long.
"Tony!"
"Relax and lie down on the examination bed and pretend to be unconscious or something."
Steve lied down and closed his eyes, heart pounding.
Tony had just pulled his t-shirt on when the doors slid open. He quickly crossed his arms to look nonchalant, "Those were locked you know."
Natasha rolled her eyes. "Please."
"Why are you even awake this hour?"
"I was craving a non-fat yogurt. Also because I have a hearing like a cat. I thought 'hmm, either someone's breaking into the tower, or the local genius is creating homicidal robots out of pure boredom'. I decided on the latter." She glanced at Steve.
"You aren't going to let that go are you?"
"Nope," she said distractedly. "How's he doing?"
"Peachy. He was banging—I was banging together metal parts for my contraption here," he walked to the console that controlled the gas room and patted the top of it.
She walked up to Steve and scanned him.
"You must be wondering what this very interesting looking device does."
"No." Natasha laid a hand on Steve's forehead. "He's all sweaty. Is he sick?"
"I think it's just really warm in here. Don't you find it really warm in here?" Tony tugged the collar of his shirt.
She looked at Tony suspiciously.
Dammit Tony, you're so obvious.
"Hang on," she said. "Why are you so sweaty?"
"Uh-hum…" Tony was lost for words.
Oh what the hell. It's Natasha afterall.
Steve sat straight up and casually smiled. "Hey, Nat."
AN: Steve has some explaining to do. Sorry about the 4 year delayed update!
