Smutty chapter ahead. Tony receives his birthday present. ;)

Chapter Twelve

Tony shivered. He honestly could not believe it. He was actually inside of Pepper Potts. If someone would have told him a few days ago that he would be having sex with the woman he fantasized about on a daily basis, he would have laughed in their faces. I mean, it had taken what...almost a decade for them to finally admit their feelings for each other? They had both played their game of avoiding their true feelings for so long he never actually thought they would get to the end of it. He had begun to view it like starting a game of Monopoly and realizing four hours later and at three in the morning that nobody is even close to winning and just giving up. Although, he was almost positive he would have never given up on her. Screw Monopoly. Metaphorically speaking of course. Now screwing Pepper...that he was actually doing that at the moment. Literally. He let out a soft chuckle at the thought and lowered his face to Pepper's neck to give her a gentle kiss.

"What's so funny?"

"Nothing." Tony decided telling her about his Monopoly analogy might ruin the mood so he kept it to himself. "Just glad we finally got here, is all." That most definitely was not a lie. When his lips lingered just above the pulse point on her neck for longer than necessary, he felt Pepper huff indignantly, and he was barely able to suppressed his grin.

"You know I love you, but could you stop over-analyzing everything the way that you do and start moving, Stark?"

Tony felt her hands grip his ass out of pure desperation trying to urge him into motion. He chuckled at her impatience, flicking his tongue out to taste her skin. She tasted like heaven. The woman underneath him trembled as he lazily licked his way up her neck to her ear to whisper, "I thought this was my present, Pep? Maybe I want to savor this moment. It's been a long time coming." Then he pulled back and gave her his one hundred-watt Stark smile of mischief.

Letting out a growl of frustration, Pepper threw her head back into the pillows, not even trying to hold back the glare she was giving him. That irritated gaze made the most sensitive part of him twitch with desire. When she was upset with him, she was fucking hot as hell. Pepper was a firecracker and it was all too easy to light her fuse. He knew exactly how to set her off. "Speaking of a long time coming..." she started.

He pulled all the way out and thrust into her a second time, fully sheathing himself in her. Whatever she had been about to say was cut off with a loud squeak, and he savored the fact the annoyed look on her face was immediately gone and replaced with that of delight. "What was that you saying, Pep?" Tony asked trailing kisses up her jaw to her ear where he bit down on her lobe before tracing the shell with his tongue. "Something about coming?" He blew a stream of air into her ear and felt her inhale sharply. All he got out of her in response was a string of unintelligible mumbo jumbo that made him laugh as she threaded her fingers through his hair and pulled at it gently. He groaned at the sensation and felt those long legs he loved so much tighten around him, urging him to go deeper. He wasn't about to deny her now.

She was so wet. So warm. So tight. So perfect. He buried his face into her neck, letting her comforting scent permeate his every cell as he moved inside her. The feel of her nails scraping over the skin on his back and her hips rolling up to meet his was going to push him over the edge faster than he really wanted to go. Although, this was definitely only round one. He planned on keeping his promise of her not being able to walk when he was through with her. He usually had a pretty quick recovery time anyway and with Pepper, he wouldn't be surprised if it was even shorter than usual. He wasn't going to stop until they went twelve full rounds or he got a TKO where only he could be the one who could determine if she would be allowed to tap out.

"Tony..."

Her voice brought him back. It was what always brought him back. The breathy way she said his name made him shudder with pleasure. He could listen to her say his name all damn day long and never grow tired of it.

"Tony..."

He nuzzled her cheek, making sure his facial hair tickled her overly sensitive skin. "Yeah, baby?"

"Talk to me. I want to hear your voice."

He quirked his brows, actually a little shocked by her admission. He was almost sure she was most happy when he kept his mouth shut and now she was asking for him to speak? "My voice?"

Pepper pushed him back in order to meet his gaze. The flush on her cheeks and desire reflected in her eyes made him swallow deeply. The way she was looking at him could have gotten him off in itself. She reached out to run her fingertips lovingly down his cheek. He leaned into her touch as if he was unable to get enough of it. He was pretty sure her touch was his new drug of choice. "Yes. Your voice, Mr. Stark. Your voice gets me tingling in all the right places."

His eyebrows shot skyward in surprise before pulling together in confusion. "Seriously?" Wow. He had no idea. If only he had known this months ago. He so would have used this to his advantage. The Pepper Potts was turned on by the sound of his voice? God, is that why she always bantered with him...because she loved hearing him talk? Fuck was that arousing to think about.

She smiled warmly at him, reaching out to brush his sweaty hair back from his forehead in a tender gesture he had always loved. "Don't be so shocked. You already know you are a good looking man, Mr. Stark. Is it so hard to believe your voice alone is enough to make my panties wet? You honestly wouldn't believe the number of times I've had to change my underwear after a board meeting because of you and your sexy as hell voice. You could be reciting pi for all I care."

His Adam's apple bobbed as he swallowed thickly. Oh God. Holy fucking shit. Because of her admission, he was going to lose it right there like an inexperienced teenager. "Pepper," he growled lustfully into her ear as he sped up his thrusting. Her happy moans of pleasure in response was music to his ears. This woman was going to drive him absolutely fucking crazy and he would gladly lose his mind for her."My God, Pepper. What did I do to deserve you?" His mouth found hers and he thrust his tongue into her mouth, devouring her for several long seconds before ending his kiss with a nip to her bottom lip. "You drive me crazy, Virginia Potts, but I wouldn't have it any other way. Would you believe the sound of your heels announcing your approach got me hard every single time? Do you know how difficult it is to design tech with a raging hard on? Hell, it was hard to even remember my own name."

At his admission, Pepper could barely form words as she tossed her head from side to side, moaning and gripping onto him for dear life. Now he was the one driving her crazy. Seeing her lose her mind like this was a thing of beauty. The Pepper he was familiar with was always in control. That's just who she was. She didn't like giving up the reigns to anyone because she always got things done. Watching her lose it because of him, only drove him to fuck her harder. God. He could get use to this. He really could.

The feeling of her walls tightening around his dick and the way she was writhing underneath him was a signal she was close. Very close. "That's it, Pep. Let go. I want to hear you. I need to hear you. Come for me." His mouth latched onto her right breast, sucking her pebbled nipple into his mouth. That's when she lost it completely, arching upward as she came hard against him, hands buried into his thick hair as she shouted his name over and over. As she was coming back down from her high, he continued to move inside of her, trying to draw out her pleasure as long as possible, pressing kisses to her face as she focused on slowing her breathing.

He wasn't far from finishing himself but was trying his damnedest to hold off because he wanted to make her come at least one more time...two times if he was really lucky before finishing himself. But it had been so freaking long since the last time he had been with someone. It had been before Afghanistan and before that, he usually brought a girl home several times a week. More than that if he was done with a project. Less than that if he was in the middle of one. Since coming back, the only attention his dick had gotten was from his own hand.

Even so, he believed himself to be a master over his own body. Mind over matter. All he had to do was just think about something else, and he would last. Think about his suits or boxing with Happy or God forbid, Justin fucking Hammer, but when Pepper grasped his face in between her hands, establishing eye contact once again and the words, "I love you, Anthony Edward Stark," left her lips, nothing he could think of could stop himself from tumbling over the edge as his own orgasm slammed into him. Now it was his turn to call out her name as he emptied himself into her. Just when he thought it was over, another wave hit him and threw his head back. Holy fucking shit. The orgasm seemed to go on forever. Was it only his imagination or was his heart stuttering? Oh God. What if the arc reactor was failing because the effects of the palladium poisoning were worse than he originally calculated? That wasn't likely but if he died now at least he would die a happy man. When the waves of his release finally dissipated, he collapsed into a boneless shivering heap onto Pepper's chest, trying his hardest to regulate his own breathing while not crushing the woman underneath him.

"Love you too, Virginia 'Pepper' Potts," he mumbled against her cooling skin when he was finally able to form words again. Only this woman could make his IQ decrease by a hundred points by giving him the best orgasm of his life. He rolled off of her and onto his side where he pulled her against him. He shuddered as she traced around the outside of the reactor. "I was planning on a longer run than that. Look what you made me do. God, woman."

"It was an amazing start." Pepper giggled, propping herself up on an elbow to stare down at him. Her ocean blue eyes were glinting mischievously as they raked over his body causing Tony's heart rate to spike. "Well, since you made me see stars I think it's time to repay the favor. You ready to receive your birthday spanking?"

Tony's mouth went dry. Yep. Heart failure. He was in heart failure. Pepper was staring down at him like he was a piece of meat and she wanted to devour him. It was so fucking hot. Desire spiraled down to collect in his lower regions. Jesus. Maybe he didn't need any recovery time.

"What are you waiting for, birthday boy? Roll over." When he didn't immediately obey her command, she took matters into her own hands and rolled him herself before climbing onto his back to straddle him, pinning him to the bed. "Is this okay? I'm not hurting you am I?" There was concern in her tone.

Ah yes. Not long ago, he had been hit by a car. He had honestly forgotten all about his bruised abdomen until she brought it up. He was pretty sure the woman on top of him could make him forget about a lost limb. "Nope. Not hurting me at all. This is definitely okay. Trust me. This is more than okay." He sucked in a breath when Pepper's hands grabbed his butt and gave it a tight squeeze.

"Do you have any idea how long I've wanted to do that? I love your ass, Mr. Stark." Her delicate hands massaging his glutes drew a groan from deep within him. He sunk into the pillows as she worked her magic with her fingers. God. She really loved his ass that much?

Suddenly, the ministrations stopped, and he could feel her hot breath on the crack of his ass as she bent over him, feel the wetness of his juices and her own on his back where her hot core was pressed against him. Fuck. Fuck. Holy fuck. He gripped a pillow tightly in his hands to try and anchor himself to something when all he wanted to do was grab her, pin her down and bury his face in her pussy.

"Especially when you wear those jeans that cling to your curves. God. Your ass is delicious. It's a delicacy I've been dying to try." And then he felt her teeth embed in his right cheek before he felt the wetness of her tongue as she licked where she had bitten.

Like a bucking bronco, he came off the bed, almost throwing her to the floor in the process. "Fuck, Pepper! Fuuuuuck!" Jesus, Mary, Joseph and all the saints. This woman. What was she doing to him? In the end, it didn't matter. She could do whatever she wanted to him and he would love every fucking second of it. She owned him: body, heart and soul. He wondered if she knew that.

She re-situated herself back into her earlier position. "Calm down, Mr. Stark. I have barely begun." And then she nipped at his other cheek before soothing it with her tongue.

Desire shot through him, and he pushed his head into the pillows to try and cover his loud groan. It was like putting a silencer on a gun. It made it a bit quieter but it really didn't work.

"Are you ready to receive your spanking now?"

Tony could only nod weakly because he could feel her nose nuzzling his rear, and he thought if he tried to speak, he would only squeak.

"I'm going to need a yes or no answer."

"Y-yes." His answer was more of a yelp than anything else because she was toying with him with her tongue.

He felt her chuckle before she squeezed his ass again. "Please respond with, yes, Miss Potts."

"Yes, Miss Potts," he repeated. It took a hell of a lot of concentration to say those words and not become a stuttering mess. This entire situation he was in was shocking the hell out of him but in a good way. In his wildest fantasies, he could not have imagined Pepper doing this to him but here he was about to receive a spanking from his PA...no wait, his CEO. The CEO of Stark Industries owned his ass. Literally. Okay, it was official. Pepper Potts was a lady in the streets but a freak in the sheets. She was the absolute perfect woman.

"I won't give you the full spanking until I know you can handle it. If you want me to stop at any time, just tell me. How about we start with five and see how you are? I want you to count out loud for me."

"Yes, Miss Potts." When he felt her hand pop his ass, he yelped more in shock than pain. It smarted a little but it wasn't anything he couldn't handle. He almost forgot to count. "One." The second smack was a bit harder, and it was then he realized he was hard too. "Two." The third slap rang in his ears. He wiggled helplessly against the sheets, trying to gain some much needed friction to release some of his growing arousal. "Three." His cock was throbbing now. He was sure at this point he had no blood left in his head. Fuck. He was suppose to be counting. What number was he on again? He was worse than a preschooler. He couldn't even count to five.

"You still with me, Stark?" Pepper purred into his ear. She had turned around and had taken to nuzzling him in one of his most sensitive areas. The ears. Dear Lord. Not the ears."Did you lose count?"

"Y-yes, Miss Potts. I mean, n-no, Miss Potts. I mean I'm still with you but I didn't lose count." He suddenly remembered where he had left off. "Four, Miss Potts. Four! It's just you doing that is making me...it's making me. God, Potts." He ground his hips into the bed to show her what he meant. "It's hard not to flip you over and fuck you into the mattress."

His actions made her laugh. He was frustrated, and clearly she knew it. He honestly didn't know how much more of this he could take. It felt like he was wound so tightly he would explode into fragments. Telling her he was done was on the tip of his tongue until felt her hand slide underneath him to grip his pulsing cock. He gasped and shuddered as she stroked him lazily. The pressure of her hand and his own body against his dick made him moan. "So I take it your birthday spanking is to your liking?" When her hand fell on his ass the final time, the pleasure that coursed through him almost made him blackout. Christ on a cracker.

"Five!" He shouted as he came into the sheets.
