The sound of the elevator is what drew Pepper out from her working stage. Stark Tower was now their home. Stark Industries was still in Los Angeles, California, but Tony had convinced her that working from Stark Tower remotely was more safe, considering SHIELD was somewhat on call, and the rest of the Avengers regularly appeared and disappeared. He merely told her that Stark Tower was more suited for her safety, and he had already built a few suits and stored them in the tower, so there really was no rush into reconstructing their Malibu home.

The elevator doors opened, revealing a very relaxed and smug Tony Stark. He was dressed in a t-shirt, dark blue pants, and a sweatshirt. He said something to her, before he left, about talking to Bruce Banner. Before she could utter a word, he was already out the door, so, most likely, he had just gotten back.

Despite the noticeable absence of the teal glowing piece in the middle of his chest, she had come to the conclusion that it didn't matter if he had his Arc Reactor or not. The soft teal that she jokingly dubbed as her nightlight wasn't permanent, and she knew that. What made her feel like nothing had changed was the fact that he was still the same Tony Stark that she fell in love with.

He was still an egotistical jerk, but he had his soft moments. He didn't let the missing hole in his chest bring him down or affect him; he still built suits, despite what he said about becoming a changed man. You can take the machines away from the man, but you can't take the man away from the machines.

Pepper turned her head to greet him. Her red lips formed a smile as her eyes sparkled, taking in his presence in one swoop. "Hi." She said, setting her laptop down on the glass table in front of her.

"Hey." Tony responded with a warm grin. He pressed himself against the back of the couch and hovered over her, giving her a quick kiss. He then rounded the couch to sit down next to her. "How was your day?"

Pepper pointed to her laptop, as if he were expecting a different answer. Tony winced at the painful memory about a promise regarding a little more effort from his side in regards to managing his company.

He tilted his head to the side, giving her his best puppy dog look. His hand grazed her thigh. "But you do it so well yourself." He choked. "I don't want to screw things up."

She rolled her eyes, but still kept her smile. "Tony, I thought we agreed, you get to build your suits of armor, but you have to promise–"

"–To do some house work for the company," He finished with a huff. "I know." He looked down at his hand that began to slowly drift up her thigh and into well known territory. He stopped half way to gaze up at her with a small frown. "I've been busy lately, you know, recovering from the surgery, and trying to keep up with everything that's been happening – Fury and all that stuff."

Pepper looked at him sympathetically. "I know." She admitted. She had bothered him about contracts that needed to be signed for the necessary repairs to be done on their Malibu home, but a part of her realized that him dodging the subject, and the matter entirely, was probably because he wanted to move on from that part of his life.

Pepper reached up, gently cupping his cheek, and smoothing away a bit of dirt. Tony looked lovingly into her gaze and began to grin. He loved these moments between them; small, romantic, but so meaningful and powerful. It made his heart beat faster with each passing millisecond.

"I know it feels like one of those romantic nights, but I'm really exhausted from talking to Bruce about seemingly nothing since he dozed off on me." Tony patted her thigh. Pepper smiled to herself, almost in anger.

They didn't talk about having sex that much – it just happened on its own sometimes. They'd look into each other eyes, kiss each other, and seconds later, they'd find themselves rolling around naked underneath their sheets or on the rug.

It had been a little over a week and a half since they last had sex, and Pepper was almost positive that Tony had a higher sex drive than she did, most likely a theory that stemmed from her work as his Personal Assistant. A week and a half, plus one day, of no sex was not what she wanted.

Thankfully, Pepper wasn't dressed in a crisp pressed business suit, because she wouldn't have straddled his lap if she had.

Tony widened his eyes as her leg had unexpectedly swung over his lap. His hands were now in the air, not quite sure what to do with them. He was more shocked than turned on. "Pepper." He gasped, still trying to process what was happening.

Pepper wore short cut shorts; not as short as the ones she wore when Agent Coulson made an unexpected visit. She slid her hands along the contours of his neck, watching him shudder underneath her body once they reached the hairs on the back of his neck.

"Oh god." Tony managed to choke out. "Did you break into my personal database of fantasies, because this is number twenty-three. It had a three and a half star rating." He rambled.

Pepper smiled at his uncontrollable rambling. She slowly grinded against his pelvis; her rough jeans moving along with the crisp material of his pants. Tony closed his eyes in pleasure as he felt the material move along with his boxers, rousing his cock awake. God, he missed this side of her so much, dominating and taking charge. He couldn't even begin to explain how much CEO Pepper Potts turned him on. It was the main reason why he tried to avoid her constant badgering about all things Stark Industries related.

"Pepper..." He grounded out.

She sunk her head in the crook of his neck and gave it a light feather kiss. At the same time, Pepper began to grind against him a bit faster. His cock was half awake now and working its way towards a plea for release. He wanted to grab her by the hips, yank her around so he was pinning her against the couch, and fuck her hard and fast, but a dominating Pepper was something he wanted to see for a very long time.

As his forehead rested against Pepper's shoulder, he was forced to bite his bottom lip or else small tiny whimpers might've escaped. Thanks to her work, his erection was now very visible through his pants, and Pepper noticed right away, as the tiny moan that escaped her lips were caused by the sudden pleasure from grinding against his hardened bulge.

"Tony." She moaned. Pleasure soared through her body as she continued to grind against him. He didn't notice yet, but just his bulge alone was getting her thoroughly wet. She lifted her head up from his neck and rested her forehead against his. Both of their eyes were closed as they tried to savor every single ounce of pleasure they could get.

"Pepper." Tony finally grounded out. "If you keep this up-"

"I know." She said with a small devilish smile. When she opened her eyes, she saw his focused expression. God, did she want to watch him come against her body. Tony's eyes flew open once he noticed her lack of movement on top of him.

Before Tony could utter a word, Pepper was already attacking his belt buckle. Her fingers fumbled with the latch, but she got through it within seconds. Tony's hands were still up in the air and just watching her attack the zipper on his pants made him very aroused, almost to the point where unexpected whimpering, urging her to just fuck him already, was going to escape his lips.

Pepper pushed his pants down a little bit, giving her enough room to push his boxers down far enough so she could wrap her hand around his pulsating cock. Tony gasped and shuddered as Pepper's fingers reached around his hard member.

His arms gave out as they landed next to Pepper's wonderfully toned calves that were digging into the couch. "Pepper..." He drew out in a moan.

She sat on the spot above his knees, and as she leaned in to give him a hard kiss on the lips, she gave his cock a couple hard, yet lazy, strokes, making him whimper. When she pulled away, she took a few seconds to observe and remember his expression.

He looked like he was drowning in pure pleasure. His head was tilted up slightly, and his expression was lazy and wanting, almost pleading her to keeping going, but slowly and painfully. She felt his rough hands rub against her bare calves, urging her to continue.

Pepper gave his member one, two more strokes and let it bob free. As she began to give him wet and passionate kisses with one hand on his shoulder, she used her other hand to unbutton her shorts and tug them down. Tony noticed her struggle and reached around to help her. She unattached herself from his lips, climbed off his lap, and pulled her shorts off, leaving herself in a white blouse and black lacy panties. Tony licked his lips as he glanced down at her moist, black, teasing clothing.

Pepper didn't climb back on her stallion just yet. She wrapped her hand around his hard pulsating cock and stroked him hard, up to the point where pre-cum began to dribble out. After a few drops escaped, she stopped and took her time in spreading the liquid around the head. She heard Tony gasp loudly as her thumb continued to tease the small hole on the top.

"Pepper." He grounded out. "Please-"

Pepper was beginning to like this a little too much. "Please... what, Tony?" She responded seductively.

His hips frantically thrust upwards, trying to gain more friction from her hand. "Please-please-please-please." He repeated achingly.

"Tell me what you want." Pepper growled before straddling him once more, her wet clothed core hovering over his throbbing cock.

"Oh god, Pepper!" He exclaimed loudly. He couldn't control himself, or his mouth, anymore. "Just fuck me already!"

Pepper, mesmerized by how masterfully Tony could control his own free will under such sexually frustrating circumstances, smirked as his words, and pushed her black panties aside, giving Tony a perfect view of the pleasure to come.

His mouth gaped, and at one point, he was borderline drooling. He began to impatiently thrust upwards, trying to get her to sink down on his hard cock already, but she was enjoying the sight o him squirming. Pepper stroked him slowly, and began to rub the tip of his cock along her soaking wet folds.

Tony choked out a loud whimper and then a cry. His free will, that he was so proud of before, was now crumbling at an exceeding rate. Before Pepper knew it, his hands were roughly gripping her hips, slamming her down onto his needy cock.

Pepper shouted in more pleasure than pain as Tony angrily, and repeatedly, impaled her. She crumbled against his hold, gasping and crying against his ear, begging him for more. He thrust a bit faster, and almost fell over the orgasmic edge when he felt her tight walls begin to expertly milk him.

"Honey." He moaned against her ear, hugging her against his body. "Oh god, Baby."

When she felt his thrusts become shallow and slow, she took the opportunity and began to grind hard against him. As he rocked and grinded with her, he pulled away to stare up at her blissful expression. What he saw made him smile. Pepper was riding him, slowly and effectively, but she was smiling. Her eyes were a soft shade of blue, and she looked content and happy.

Her expression changed when she felt the center of her body tingle with pleasure. She rode him hard, making him squeak and moan loudly. "Christ, Pepper!" He yelped in pleasure. She placed her hands on his shoulders and rode him harder, frantically trying to bring herself over the edge. She was panting and moaning alongside him, trying to draw out the much needed orgasm.

The thought of Pepper roughly riding him into orgasmic bliss drove him over the cliff. He came with a shout, shooting hot streaks of come inside her at a frantic pace, and continued to thrust into her. The feeling of his hot white mess shoot inside her shook her hard as her orgasm took over her body. She clawed at his shoulders, leaned into his chest, and gasped for air.

Tony's breathing hitched as the last drop of come left his body. He continued to grind against her for a few seconds before stopping indefinitely. Pepper's breathing was beginning to return to normal as their much needed sex session came to an end. He slowly enveloped her, pulling her against his chest and into his arms.

They lay there; her head rested against his chest where the Arc Reactor used to be, and his chin rested comfortably on top of her head. They both needed the stress reliever, and Tony was happy she took the initiative in the first place, because if she hadn't, they'd be fast asleep, regretting another day where they were, again, deprived of sex.

Once her breathing returned to normal, she apologized. "I'm sorry."

He rubbed her bare shoulder in affection. "Why?" He asked. "What's there to be sorry for?"

She shrugged. "You said you were tired, and I took advantage of you and-"

"Pepper." He stopped her. "Don't apologize for what happened. Do you realize how sexy it is when you take charge? I say you should do it more often, and only in bed with me, because you do far too much of it during business hours."

"You're not just saying that because we finally had sex on the couch, right?" She asked.

"Not entirely." He admitted. "Although, next time, do you think you could fully take my pants off? If you weren't so hot riding me, the chafing from the zipper would've gotten to me."

"Oh, sorry." Pepper breathed a laugh. "I got a little too excited."

He laughed and kissed her head. "Yeah, I noticed. I also noticed your love for dominating me. Want to tell me what that's all about, Potts?"

She shrugged. "Dominating the infamous genius, billionaire, philanthropist that doesn't like taking orders from anyone?" She paused to grin wildly. "Doesn't take a genius to get the hint."

"So, dominating me is one of your kinks?" He raised an eyebrow at her. "JARVIS, write this down. It's vital information that I cannot simply forget. Pepper Potts Kink number one; dominating Tony Stark."

"Shall I add it to the list of things not to forget, including a dozen eggs, Sir?" JARVIS asked.

Tony furrowed his eyebrows as Pepper laughed.
