Steve stood outside of the yoga studio, staring through the large window at the people bent awkwardly and twisting into positions that couldn't possibly be comfortable.  His eyes were wide and you had some idea of what he was thinking, but it was the first time that your best friend was completely speechless in front of you since you met him.

"Are we the only two going to this?" he whispered, still staring straight ahead.  You could see him swallow heavily as he watched, laughing quietly to yourself at the sight of a nervous Steve.

"I think so, yeah.  It doesn't seem like Tony took Christmas very seriously this year, huh?"

When he finally turned to face you, his body relaxed slightly at the idea that you might be just as unsure of this as he was, knowing that he wasn't suffering with the thought of it alone.  "Are you sure you wanna go in there?"  He turned back and cocked his head to the side as he watched, "I don't know if I can even bend that way."

"Come on, you big chicken, we're doing this."  You grabbed his arm and pulled him into the studio, immediately hit with a wave of heat as you swung the door open.  "So 'hot yoga' isn't some innuendo then?  It's actually hot?"

Steve reached up to wipe a few small beads of sweat from his brow that had immediately begun to form, both from the heat of the room and the heightened sense of anxiety.  The instructor nodded towards you and pointed to a corner at the back of the room; a man of Steve's size needed the space, but you were more than happy to be away from the center of attention and away from the window that faced the busy street.

"Unroll your mat over here, and I'll go there."  You began to set up, but the instructor was approaching with a broad smile on her face that you were certain appeared at the sight of Captain America in her studio. It happened everywhere you went together.

"Hello, welcome to our little class!" she exclaimed, holding her hand out to him and yet to acknowledge you. "It's really an honor to have you here, Captain."  She shook his hand so enthusiastically that his entire arm moved with her two hands that encompassed his.  He pulled his hand back quickly and reached out to you, brining you in tightly at his side.

"Thank you, we're...happy...to be here.  Let's get started then, shall we?"

Her smile dropped ever so slightly; so faintly that you may have missed it if you hadn't been watching for it, surprised at yourself at how you felt satisfaction from her disappointment. "Absolutely, let's get started!" She moved back towards the front of the room and brought the room to attention, no longer staring at Steve as she had been since he walked in.  "Alright, everyone, welcome to today's couple's session!  Let's warm up before we get to the good stuff!"

You rolled your eyes and looked at Steve, who appeared to be holding his breath with his eyes squeezed tightly shut.  He turned his head towards you and opened his eyes slowly, doing his best to reign in his nerves in front of everyone. 

"Tony Stark is a dead man," he hissed under his breath.  "Dead."

~~~

"My hand goes where?"

"There's no way I can bend like that."

"I have to be the bottom plank, (Y/N).  I'll crush you."

"See?  I told you."

"Okay, class, for the next pose we're going to do the 'down dog assist'.  One partner will be face down to the floor with their arms outstretched, and the other will mimic the same pose on top of them.  Watch here to see what it should look like." 

As the instructor took on the pose with another member of the group, Steve sighed and shook his head, hesitantly taking his spot on the floor.  He looked at you with a smirk and a mischievous grin once he was in place, and you wondered if he might even be enjoying himself now. 

"Woof," he whispered with a quiet growl.

"Stop it!" you mouthed silently, trying to hold in the laugh that was on the verge of escaping. Taking a long, deep breath, you lowered yourself onto his back and laid against him with your head next to his.  "This isn't as uncomfortable as I expected," you said quietly in his ear.

"I can feel your boobs on my back."

"Steve!  Seriously?"

"Seriously!  I can."

"If you don't kill Tony first, he's mine," you grumbled as you pushed yourself up and off of him.  "And then you're next."

He rolled over and pushed himself up on his elbow, watching you take the next position on the floor next to him.  "Sorry," he whispered, quickly moving to join you for the final move but pausing to remove his shirt first.  "Does it have to be so hot in here?"

"It's called 'hot yoga', Steve.  I think the name really gives it away."

"Sit facing each other," the instructor began, "get really close together, and one wraps their arms around the other.  Now the one being supported leans back as far as they can...slowly...and when you come up together, greet with a kiss and then switch."

Your eyes widened and you looked at Steve, who wasn't appearing to be as shocked as you were. He wrapped his arms around your back and nodded, waiting for you to lean back.  If you thought you were nervous before, that was nothing.  You clasped your hands behind your back and began to lean, finding that your eyes were trailing down from his face to his chest and stomach until you were too far back to continue to enjoy the view. 

He held you there for a moment, watching your body stretch, trying to keep his mind from wandering too far from the present.  He never looked at you the way he was right now, and even though you couldn't see him, you knew full well what was happening.  When he brought you back up to him was he going to actually kiss you? Did you want him to?  You didn't have time to answer your own question before it was upon you.

Or rather, before Steve was.

"Alright," he sighed, "enough."  He pulled you up to him so quickly and urgently that you heard the instructor gasp from the other side of the room.  His arms wrapped around you forcefully, lifting you off the floor and onto his lap, your legs still wrapped around him.  You took his face in your hands when your lips finally met, hearing a contented and soft moan from his chest. 

"So, it looks like you two really enjoyed your first yoga experience?"

Steve stopped and sighed, leaning back slightly to give the instructor a look that should have made her fear for her own safety, but being Captain America, he toned it down but still easily made his point.  "Yes, we did," he said flatly, moving you so he could stand and grab your hand to join him.

"I thought it was great," you said to her with a smile, "I think we should do it again, don't you, Steve?" Reaching up, you ran your finger along his jaw line and smiled coyly, turning to grab your mat and walk towards the door.  It was a shock how fast your relationship had just changed and how unexpected it was, but looking back at the expression of both surprise and longing on his face, you wondered why it had taken so long for you both to see it.

You grabbed your phone from your bag and hurried to shoot a text out before Steve joined you, deciding that maybe your threat to murder Tony Stark was a bit premature.

Thanks for the gift, Tony.  Best Christmas ever. 

I knew it.  I'm so good.

~~~

Two weeks later you and Steve decided to give the class another try, but the tone was completely different than your first experience.  To say you had been dating would be an understatement; you were in a full blown relationship and had been inseparable since that first day.

Steve carried you into the studio on his back, the two of you laughing so loudly that the class stopped to look at you and stared until you realized what you had done.  He gently lowered you to your feet and guided you to the back of the room, keeping his head down and his mouth shut.  You had to stifle your laugh as you rolled out your mat and began to stretch, seeing the red in his cheeks from the minor embarrassment.  How was he ever going to get through your plan to repay that annoying instructor for her untimely interruption at your last class?

"Okay, class," she began, "now that we're all here, let's take our first pose-"

"Excuse me," Steve interrupted, standing up to address the group, "if you don't mind, since our first class, (Y/N) and I have found a few other poses and positions that we think you might enjoy more."  He looked down at you and winked, and you immediately felt your face heating up under his gaze.  "I know we have."
