A/N: Another Avengers fic! This will be a Stony central story, based on my video OH STONY! on YouTube. Check it out, but try to refrain from doing so if you don't want spoilers. Be warned, lots of feels and heartbreak and more feels. Did I mention feels?

The Avengers Tower was as quiet as possible, since it was about 2:00 in the morning. Most of the occupants had retired to their individual suites, courtesy of Tony Stark. JARVIS detected strange behaviors all around, but worried not in the slightest since the AI had grown accustomed to Sir's unique housemates.

Clint was "nesting" up in the ventilation system. He hardly ever slept in his room. Natasha was staring out her window, polishing a dagger with her bed sheet. Bruce was reading a book, obviously trying to calm his nerves...well, the Other Guy's nerves...so he could try to get some sleep. Tony was in his workshop working on a new "toy" he wanted to have ready to show everyone in the morning, well, once the sun came out. Steve was tossing from a supposed nightmare, which, to his dismay, still occurred frequently, thanks to the PTSD. Thor was the only one conked out, snoring louder than ever. A thunderstorm paled in comparison, which was why Tony made the Asgardian's suite soundproof. All was as normal as could be, until JARVIS detected something.

"Sir, I have found a bug in my system, hindering me from seeing video and audio footage."

"Hang on, J." Tony was biting his lip in concentration. Just a little more...GOTCHA! He discarded his goggles onto the workbench, and wiped the sweat from his brows. "Talk to me." The genius cracked his knuckles and started typing furiously on his keyboard, bringing up the security system JARVIS had on him.

"It appears as if the feed is being manipulated by an outside force."

"Well, not for long. Nobody hacks into you and gets away with it."

"I appreciate your fondness of me, Sir."

"Yeah, well, you don't want my head to explode, since it can't get any bigger."

"Sir, I have never had the intention of harming your very fragile ego."

"Who made you such a sarcastic know-it-all?"

"You, did, Sir."

"Right you are. Now, I've got the little sucker." A few minutes later, the hacker was defeated and Tony threw his fist up in the air in triumph like he was head of the Breakfast Club. "He won't be coming back for long...how are you?"

"I believe systems are in check. No sign of interference."

"Great, now where was I?"

"Your surprise, Sir."

"Oh, yeah! What would I do without you?"

"Forget where the light switch is."

"That's why you're here!"

Steve got out of bed, beads of sweat resting on his skin. Panting, he got out of bed and headed to his adjoining bathroom. Running cold water, he splashed himself and stared into the mirror. His pupils were slightly dilated and he looked like a train wreck. He felt like one too. In his dream he was on that damn train again with Bucky. And he couldn't reach him, no matter what he did. Bucky just kept falling. Over and over and over again...

Steve was calmed down enough to return back to bed, but a surprised waited for him when he entered his room.

"Tony?" Steve was shocked. Tony never went to bed at this hour. Steve knew this because they had been dating for about a month now, starting right after the Ultron incident. "What are you doing? I-I mean, I'm glad you're coming to sleep, cause you need it, but...is something wrong?"

Tony stepped forward, pulling his shirt off aggressively. "I want you."

Steve smiled. "I want you, too. Always have. You know that."

"No. I want to take you."

Steve raised an eyebrow, clearly confused. "It's the middle of the night. Where would you possibly want to take me that can't wait till morning?"

Tony walked slowly towards Steve, and Steve could not help but stare at that glowing light inside his boyfriend's chest. It was so beautiful. It kept him up at night because he could not stop marveling at its beauty. Tony stopped when he was inches away from his face.

"T-Tony?"

"I want to take you somewhere you can't even imagine."

Steve actually got that reference. "Oh, c'mon, babe. We talked about this. I love you. I'm just not ready for-" Steve was cut off by Tony's harsh kiss. It seemed more aggressive than usual. Steve hummed in disapproval and shock, trying to gently press Tony away, but Tony seemed stronger than normal. Steve hissed in discomfort as a hand cupped his member, squeezing it mercilessly. His pants seemed to just fall down on their own as he was thrown back onto the bed. "T-Tony..." Steve was panting hard.

Tony jerked the pants off his ankles, then crawled rather sexually on all fours till he was on top of the super soldier. "Shhhhhhhhh...Captain..."

Captain? Tony never calls Steve that. The thrusting began, slowly and rhythmically. Steve had to take a double take, only now realizing his boxers were...gone. How did he miss that? He must really be out of it tonight.

"Tony...please...not like this..." Something must be wrong with Tony. Tony had promised he would wait until Steve was ready. Steve had believed him, even though he was really really annoyed.

"On the contrary...I'd much prefer it this way." Tony hissed. Hissed? The rhythmic thrusts sped up, the super enhanced heart pounding in Steve's chest. Steve couldn't help but moan in pain, but at the same time, and he hated himself for admitting this to himself, he enjoyed it.

"TOOONY!"

"SAY MY NAME!"

"T-Tony!"

"SAY IT!"

"Ton-y...oh, God!" Steve came within seconds, shame covering him moreso than his own seed.

Tony laughed then got up, redressing. "Now you are mine." The door shut behind him quietly, leaving Steve alone.

The soldier's mind was racing. Did that really just happen? How could Tony do that to him? Sure, his playboy reputation preceded him, but Tony had assured Steve that he was different. Was he just another toy? Disgusted with himself, Steve got up and went to the shower, trying desperately to wipe away the embarrassment and downright fear that cloaked him. He let the tears fall as he let his emotions go and his guard down. Not that he had it once Tony was through with him.

A/N: Wow. OK, please be gentle with me. This is my first sex scene I have written, and there was a lot of blackouts just because I'm new at this. I've read a lot, but haven't written any. So, now, this brings us to the beginning of my video...I didn't include this in my video because I don't have the programs to edit something this sexual. But this is why Steve is like "You know damn well why, back off!" Just putting things into perspective. Please follow and review!
