You hadn't been in the Avengers Tower before. It wasn't because of Steve's doing. He'd invited you to do things there several times, but you hadn't wanted to meet the other Avengers. You told yourself it was to protect him from awkward questions. Really, though, it was you who didn't want to answer awkward questions because you had no good answers.

He took you to his floor. It wasn't quite what you imagined it would be. There weren't many things you'd consider pieces of him there. It was more generic, like hotel decor. He didn't spend much time there, though. Most of his downtime was spent either in your apartment or his.

You both changed into exercise clothes — him in one of those tight white t-shirts you loved to see him wearing and gray sweatpants and you in a fitted tank top and shorts. You walked together to the gym.

There was a set of exercise mats on the floor, and you followed him there.

“Okay, what do you do if someone comes at you?” he asked.

“Run away?” you replied.

“He's faster than you are.”

“Try to kick him in the family jewels, which I am not doing to you, by the way. I'm too fond of them.”

He laughed. “Grab me and try to restrain me.”

You walked up to him and got a tight hold on him.

He released himself and slowly and probably as gently as he could to be effective knocked you to the mat on the floor. The wind was knocked out of you as you landed, but you weren't injured.

“Did you see what I did?” he asked.

“Yeah,” you replied.

“Try it.” He grabbed you.

You managed to partly get away, but he pinned you down to the mat, face hovering inches above yours.

"You did good for your first try."

“I don't think I can learn this from you,” you said, heart pounding.

“Why?” he asked. "Was I too rough with you?"

You grabbed the back of his head and pulled him forward to kiss you.

“Mmmm...” His tongue slipped into your mouth, tangling with yours.

You rolled your hips up to make contact with his obvious erection. The semi-public nature of the gym was a major turn-on. Everything had been behind closed doors, even small pecks on the lips.

He broke the kiss. "We should go back to my room."

"Why not here?" you asked. "You said pretty much everyone is gone. I want you now."

He paused for a moment before kissing you again.

You reached down the best you could to tug at his sweatpants. Foreplay be damned. He got up and pulled them off with his boxers. You used your sudden freedom to kick off your shorts and started to tug off your shirt.

"Leave it on in case someone comes in."

You nodded and laid back down on the mat. He positioned himself between your legs eagerly and rubbed his cock against the wetness that had collected there.

"You weren't lying about wanting me now," he commented as he positioned himself at your opening.

"I like when you pin me down and use some of that strength you have."

He pushed into you slowly until his hips met yours. You ignored the uncomfortable burn. He remained still, one hand hand tangled in your hair, kissing you unhurriedly as you adjusted to him.

"How do you want it?" he asked as he began to withdraw.

You paused to deliberate. "Hard and fast. Make me scream your name."

"Don't be too loud." He chuckled as he thrust into you hard, just like you asked, and gradually built up the rhythm. His eyes were locked on your face, gauging your reactions and adjusting his thrusts accordingly.

You'd never been able to push him to the point of being tired or sore, and his refractory period was almost nonexistent. It was definitely nice to have what you could handle and the time as the only constraint on your sex life.

"Yes," you moaned. "Just let me..."

You didn't need to finish your sentence. He pushed up without breaking the rhythm so you could reach between your legs and give some attention to your already throbbing clit. It wouldn't take long.

Teasing and delaying your orgasm wasn't what you wanted this time. Your fingers made quick work of the task at hand. Even though he'd gotten better at knowing what you wanted and how you wanted it, Steve still didn't know how to to touch you the way you could touch yourself.

"God, Steve, please!" Your voice was louder than it probably should have been, but you were past the point of caring. He slammed in and out of you in long strokes as your orgasm spread from your groin to the tips of your fingers and toes. You'd be feeling it later, but you never minded that.

Steve practically yelled your name as his orgasm hit. You heard the fabric covering of the mat below you rip under his fingers. His thrusts grew slower, shallower until he collapsed gently on top of you, always careful not to crush you under his weight.

The sound of someone clapping snapped you back to reality.

"What the hell?" You turned to see Tony Stark standing about 10 feet away. This was not how you intended to meet him.

"I was going to ask if I could join your little party, but the show was too good to interrupt. Nice ass, by the way."

Steve was blushing redder than you'd seen him blush before. He didn't move, though, just remained laying there on top of you. "Tony, go away."

"I'm surprised, Cap. I still pegged you for an innocent and pure snowflake. How long have you had this little secret?"

"Tony, go away," Steve said with more emphasis.

"Who's your lady friend? I haven't seen her around before. JARVIS, has the good Captain had any other lady friends here?"

"No, sir, this is the first female guest Captain Rogers has had in the tower," JARVIS answered.

"Tony," Steve warned.

"I'll let you two lovebirds get dressed. Nice meeting you," Tony said over his shoulder as he walked out of the gym.

"That was...interesting," you said. "Will he let you live it down?"

"Not a chance." Steve sighed.

"Is he going to tell everyone else?" You probably didn't want to know the answer to that question.

"He's probably already on his way to tell Bruce."

"Wonderful." You brought your head up just so you could drop it back down to the mat again.
