No one had seen anything for over a month. After the mission to find hulk, which was a failure, Cap and Natasha had been dating for multiple months, but no one else had noticed. One day, however, Cap and Nat seemed very strange. It seemed that Tony was the only one were always talking to each other totally normal, but the way they looked at each other was different, always different. And they both seemed much more cheerful than they had ever been before. One day, he decided to ask them about it. He went to cap's room in the avengers HQ, and found him hard at work on a strategy.

"Cap," he said, " is there something going on between you and Nat?"

Steve gritted his teeth and replied, in the most normal way he could think of,

"No, why do you ask?"

"Well," replied tony, "I can't help but noticing the way you look at each other every day."

"OK," said Steve, sighing. " Do you promise not to tell anyone?"

"Cross my heart."

" Natasha and I have been dating for a while… and we might have had sex once or twice."

Tony stared in awe. " Wow," he said " the soldier and the spy. I should've known."

" Do you promise not to tell anyone?"

"Sure, but I need you to do something."

"What is it?"

" I need to train, and ever since Hawkeye left I have no sparring partner."

" I'll be there in an hour."

"See ya then"

Tony exited the room, chuckling. Steve sighed in relief. Knowing stark, not being blackmailed would have scared him. And either way, tony keeps his word.

An hour later, Steve was at the training room. When he entered, tony was already in full swing, but as soon as he noticed him enter he stopped the program.

"You're early." He said.

" I like to start as soon as possible." Steve replied.

"OK, more fun for me."

" We stop when one of us is knocked out, stark."

"Yeah, sure."

They got ready, facing each other. Stark was in his new armor, cap noticed. he threw his shield, and it came towards iron man at full velocity. Steve ran after it and dove under his legs. The shield hit tony, and as both him and the shield fell towards the ground, cap jumped up and grabbed it and plunged back down to knock him out. However, before cap could hit him, stark flew out of the way and shot him with his repulsors. Cap brought up his shield at the last moment, blocking the blast but still getting pushed back several yards.

"So," said stark, all while shooting his repulsors, " how did 'you know what' happen?"

"During the mission to shield a few months ago," replied cap, blocking the final blast and throwing his shield up to hit him. " I told her I loved her, and she said she loved me back."

" Wow, how convenient."

The shield hit his left hand, throwing that piece of armor off it. He flew back, now with only 3 repulsors and one blaster. The shield ricocheted off the wall and hit him in the foot, knocking his leg off. Now crashing, tony tried to straighten himself up. However, Steve jumped up, grabbed his shield and hit him in the head, knocking his suit out cold. Tony stood in the air for a moment, then fell on the floor with a thud.

" Pleasure training with you." Said cap, walking out the door.

" Pleasure's-" said tony, grunting, " all mine." He sighed and feel on the floor as his armor fell apart and slid off him, revealing his tightsuit.

Right outside the training room stood Natasha, in her combat suit.

" Hey, handsome." She said, grinning. "Whatcha doing?"

"Just training with tony." He answered.

" Steve, I'm a superspy. I know when there's something up."

Cap sighed heavily. " Tony found out that we've been dating. He says it's because of the way we look at each other."

" I doubt it," said nat, " he probably saw footage from the security cameras in the room we've had sex in."

As the idea dawned upon him, all previous respect Steve had found towards tony because of his deduction abilities disappeared.

" Wait," he said, " if you knew there were cameras, why didn't you take them out?"

" Because I don't really care if they find out or not. Actually, I'd be OK if they found out."

" Well, I do, so I'm gonna have to ask you to remove the cameras."

" Really? It doesn't make you feel hot knowing that there might be someone watching?"

Steve was too embarrassed to answer that question, although secretly, he agreed with her.

"Fine," he said, " but just because you want it."

Suddenly, the hallway blasted into flashing red lights, and tony limped out of the training room.

" Guys, if you're done making out, we've got a situation."

As they ran down the hallway, Steve faced tony and asked:

" What's the situation?"

"We have intruders at hall five. 5 hostiles, from what I can make out.
