Summary: Tony overhears some strange noise coming from the gym, which sounds a lot like Steve and Natasha doing the deed.
Not long after being held captive in Afghanistan, Tony had trouble contemplating sleep. He would always deny it to Pepper, but the dreams wouldn't let go. And his only way to find a piece of solace is by walking around the tower.
He decided that if he wasn't going to sleep, he might as well do some laps in the gym.
Yeah right!
As if he needs to work out at 1 in the morning. He's the armor muscle of the team. Workouts are for ladies like Bruce or Steve.
Thinking of the supersoldier, what is up with him and red? They have been quite close in the last few weeks. He might have to have Friday keep a very discreet close eye on them.
Because come on! Steve is no secret assassin spy. The old man can't learn to be discreet in this 20th century. And Nat, she does know how to keep a secret, but she's bad at social skills, no matter what the spy school taught her all those years.
Having all those questions in his mind, he didn't realize that he walked all the way to the hall that led to the basement where he built the gym so that the avengers can use to do their workouts if they wanted.
Not like he spends his time in it.
He was about to walk away when he suddenly heard some noise and a grunt. He was going to ignore it, but he's known for being too curious for his own good. He leaned against the plane of the door.
"Dammit! Stop!" He heard Steve say.
"I can't help it, you're stronger than I thought," Natasha replied. "Ugh! Why are you so enhanced?"
"Trust me, I was built like this." Steve chuckled with a groan.
Tony's eyes lit up in shock, as his jaw dropped.
Little Red and Cap are getting on it?
So Cap isn't a virgin anymore?!
He was pulled back from his train of thought when a loud banging and a deep moan came out from the walls of the gym. The intense noises coming from the said place continued growing louder and hard. This was such a hot topic that everyone wouldn't want to miss.
Before he could regret it, he pulled out his android wireless phone and told Friday to tell everyone to come quickly. A muffling sound of moaning and pants kept him from bargaining in and busting the two in the act.
About 10 minutes later, the rest of the team came rushing down the hall, everyone walking with subtle feet.
"Did we miss it?" Clint asked, biting his nails, he was anxious to know if this was true or not. And if it was true, he would have a serious talk with the Black Widow about keeping things from him.
"Still going at it," Tony informed, playing with his watch screen, really tempting to open the security camera from the gym.
Clint started pacing back and forth, as he rambled on about Nat not telling him about this. While Pepper went to pout on Tony about wasting time and not doing something productive. Bruce felt embarrassed about the invasion of privacy, and was starting to feel jealous of what relationship Natasha and Steve had when they were in D.C. Thor was the one who was really confused about what was happening.
"Ow, quit poking that at me." Natasha murmured breathlessly.
"Calm down, and don't be so dramatic," Steve replied. "You know you're enjoying it."
The sound of the floor ricocheting through the wall and the moaning got the avengers' curious eyes wide open.
"Dammit! I'm going to be having dark bruises tomorrow that I won't be able to cover up."
"Oh, you'll be bruised up alright." Natasha chuckled darkly. "You'll be walking funny for days."
At the sounds of more grunting noise made Bruce and Thor's cheeks go pink. While Pepper and Tony couldn't help but awkwardly smirk at the noise. Clint was starting to recite a personal speech he wanted to give to Natasha.
After a couple of more groans and pants, they finally heard a final sigh of high pitch ecstasy from Steve.
"You happy?" Steve sighs. "You know that I don't play when it's about this."
"You sure don't," Natasha said, sounding breathless.
They moaned and groaned for a couple of minutes later.
Pepper had to cover her ears, she had no wish in having these sounds repeating in her sleep. Thor had so many confusing questions about humans and their intimate relations. Bruce was beginning to wonder how it would have been if he hadn't turned down Nat during the whole Ultron fiasco. Clint wouldn't stop babbling about Natasha and him being so confident in sharing things. Tony was a second close to accessing the cameras inside the gym, really wanting to know if little red had finally made a man out of the old Cap.
"Ahh.." Natasha made a sound of relief. "Thank god."
Steve chuckled and said, "Was it good for you?"
"Oh yeah," Nat replied. "Just glad that we're done. I really need a shower, I'm so sweaty."
"Yeah, I could feel your skin dripping between my fingers." Steve joked, making her laugh.
"Shut up, you're all sweaty and stinky too," she replied.
"Are you ready to go?" he asked.
"Mm-hmm." she murmured. "I'm exhausted."
Steve opened the door of the gym and was surprised to find the shocking and disturbing looks of his team. Natasha came right behind him, carrying her gym bag on her shoulder.
"What?" she asked. "What's going on?"
"You guys…" Tony started to say.
"Had sex in the gym!" Pepper suddenly blurted out, covering her mouth after realizing her indiscretion.
"What?!" both Steve and Natasha shouted.
"You guys were doing a mission of your own." Pepper shyly pointed out. She didn't really know that much of Steve and she felt embarrassed for letting it out like that.
Steve and Natasha exchanged shocking looks and shook their heads in utter confusion.
"No! we didn't do any of that!" Steve's cheeks were turning red.
"We were sparring against each other for our daily workout," Natasha explained, in disbelief.
"What was all the moaning and groaning all about?" Clint asked.
"Sounded a lot like sex." Tony pointed out. "Believe me, I had wild parties that ended up like that."
"You guys!" Natasha let out a breath, pinching the brick of her nose. "Look at our sparring sticks."
Natasha held up hers and Steve's sparring sticks to show it to her fellow jarred-headed team members. "See?"
Pepper's face dropped in disappointment, "But, it sounded like…."
"Sorry to disappoint you all," Steve said. "There was no sex happening between me and Natasha."
Tony scrunched his eyebrows in suspicion, but couldn't read any chemistry between the two, "Okay, let's go get ready, we have a meeting about our next mission."
"Great, just let us get changed and we can start briefing," Steve instructed.
Steve and Natasha watched their team walk off in disappointment.
"Can you believe them?" Nat laughed off, looking over at Steve.
"I know, unbelievable." Steve agreed.
The two supersoldiers headed off to the tower's showers laughing at their friends' ridiculous suggestions.
"Good thing they don't pass by the showers, otherwise they would hear us do more than just sparring each other." Steve laughed.
"Or in your little Brooklyn apartment." Natasha chuckled, pulling off her sports bar to Steve's interest.
Steve grinned as Natasha joined him inside the shower, "Come here."
Natasha laughed and started to moan as he began a trail of kisses down her neck.
