This is an AU of my own story 'On The Runway'. What if instead of Kurt Hummel, model Harrison Potter-Black met Tony Stark? This is an AU set before the start of Iron Man. Tony is bisexual, and has never dated Pepper. There will be an age difference of approximately 10 years in this fic. I DO NOT OWN HARRY POTTER, OR IRON MAN/AVENGERS!

WARNING: This story includes slash (a romantic relationship between two men) and will include explicit content, bad language, and canon typical violence.

Chapter 1

Tony Stark was irritated. He hated being sick, and hated going to the Doctor even more. His continued illness after a couple of days of abject misery, however, had convinced his bossy little assistant that he required seeing a Doctor. He was quickly learning that it was easier to just go along with Ms. Potts when she got like this. Usually, that would make him even more obstinate. Right now though, he was simply too pitiful to object.

This is what led to his current location. Tony was trapped in the waiting room of an Upper East Side General Practitioner. Dr. Miller was well recommended, and discrete. He was also willing to work him into his schedule today. He had just sat down in an arm chair, and was waiting for Pepper to sign him in. Looking around, he noticed an elderly woman knitting in a corner, and an older teenage girl looking at a magazine with another teenager.

"God! He is so fucking hot. Such a shame he is gay." The girl said to her companion.

"Oh, I know! Those eyes! He is rich as Hell too! So not fair." The other girl said, shaking her head.

Tony's interest was peaked. Who were they talking about? He didn't think they were talking about him. They had not even looked up from the issue of Vogue they were ogling. He was bisexual, anyway. The cover was partially obscured, but he could tell there was a man on the cover, which was unusual. A few minutes later, the teenager was called back, so Tony asked Pepper to put the magazine on the table in front of him. What? He didn't like to be handed things.

He leaned forward to get a closer look, and was instantly ensnared by a pair of the greenest eyes he had ever seen. The cover featured a black haired man with the brightest green eyes. They couldn't be natural, right? His hair was styled messily, and he was wearing a tuxedo shirt that was rumpled, partially unbuttoned with the tie undone. He was giving the camera a smouldering look that made Tony almost instantly hard.

THE RESURGANCE OF MALE MODELS! The cover proclaimed. Featuring British Noble Harrison Potter-Black!

Tony picked up the magazine, and turned to the appropriate page number. Lord Potter-Black gives us the rundown on what it's like to be rich, famous, and gorgeous! For the moment, Tony ignored the article to stare at the pictures.

And what pictures they were! The man, (Potter-Black he assumed) was leaning against a wall wearing a pair of blue jeans that were not buttoned - and nothing else. His lightly tanned skin showed off the definition of his toned body splendidly. The V of his abdominal muscles, and six pack had his mouth watering.

There were also candid pictures of Potter-Black on a beach, playing in the surf with a man with copper - colored hair. The smile on the boy's face was mesmerizing. The caption under the picture read: Potter-Black in Aruba with ex-boyfriend Cederic Diggory

There were also pictures of him playing Polo with members of the Royal Family, and various pics of him walking the runway in different fashion shows. Tony turned the page, and almost swallowed his tongue. Potter-Black lay back against ruffled sheets, eyes heavy-lidded. The picture was in black and white, and the only article of clothing he was wearing was a pair of tight, white boxer briefs. They left very little to the imagination, and Tony could easily tell he was very well-endowed. Tony had never been happier that he played for both teams.

He decided then and there that he would get Potter-Black in his bed. It was only a matter of time. He was Tony Fucking Stark. He always gets what he wants.

Harrison Potter-Black was just exiting his building. He was wearing basketball shorts and a tank top, and had ear buds in his ears. He took off in a light jog, crossing the street into Central Park. After jogging for about 45 minutes, Harry stopped to take a drink from his water bottle. Tony, who had been watching his progress through the park via cameras with the help of JARVIS, decided this was the perfect opportunity to introduce himself. He had been ecsatic to discover that Potter-Black lived in New York. He was currently over seeing the construction of Stark Tower in that very city.

"Hello, gorgeous. Beautiful day for a run, isn't it?" Tony said. He was slightly nervous, though he didn't know why.

Harry opened his eyes, and turned towards the voice that was addressing him. A man was sitting on the nearest park bench. He had dark curly hair, and a very neatly trimmed goatee. His hazel eyes sparkled with good humor, and he was wearing an AC/DC t-shirt and worn jeans. He looked slightly familiar, but he couldn't place from where.

"I'm sorry, do I know you?" Harry said.

Tony knew he was British, but for some reason he had not equated that with him having a British accent. Tony found it very sexy. He was slightly taken aback that Harrison did not immediately recognise him. "We have never met before, but I hope to remedy that. Tony Stark, at your service." He said suavely, reaching for Harry's hand.

"Ah. I thought you looked familiar. Harrison Potter-Black, nice to meet you." Harry said, reaching to shake Tony's hand.

Tony was having none of that, though. He lightly grasped Harry's hand, and turned it over. He kept eye contact with Harry, then slowly leaned down, leaving a lingering kiss on the back of Harry's hand. "The pleasure is all mine." He said.

The look he was giving Harry had him feeling slightly flustered. "Charmed, I'm sure." He breathed out quietly.

"Would you join me for dinner, Harrison? I'd like to get to know you better." Tony said. He still held Harry's hand in his own, and he had no intention of bringing attention to it.

Harry cleared his throat. "I don't think that's a good idea, Mr Stark." Harry said, pulling his hand out of Tony's gentle grip.

Tony was surprised. "Why ever, not? I'm well known for having good ideas." He said.

Harry smiled wryly, and raised an eyebrow. "You are also well known for one -night stands, Mr Stark. That is something I do not indulge in." Harry said. "It was nice to meet you. Thanks for the compliment." He said, then started turning away.

Tony was nonplussed. "Wait! Please, call me Tony. I asked you to dinner, not to have sex." He said. He was not used to being turned down, and he wasn't sure how to handle it.

"You are saying you do not want to have sex with me?" Harry asked, looking slightly surprised.

Tony raised his eyebrow. "Of course I want to have sex with you! Any even slightly bent man would. You are smoking hot! But I don't only want to fuck you. I really do want to get to know you. Have dinner with me? No strings attached." He said with a slight plea in his voice.

Harry's eyes searched his face, looking for some kind of reassurance of his honesty. "I did not realise you were interested in men, Mr Stark." He said, with a question in his voice.

Tony smiled sinfully. "I am interested in both sexes - and it's Tony, beautiful." He said.

Harry wasn't sure what to do. He was obviously physically attracted to Stark, but he did not want a purely physical relationship. He wanted to fall in love. He wanted to be the most important person in the world to someone, and feel the same in return. But would he ever get that if he didn't take chances?

"Just one dinner, Harrison. Let me prove myself to you." Tony said, taking his hand again. He ran his thumb across Harry's knuckles, making him shiver.

"One dinner, Tony. Don't make me regret it." Harry said, deciding to take the chance.

Tony's face lit up with a boyish smile that made him look years younger. He was genuinely pleased at Harry's acceptance. "Don't worry, Harrison. You won't. I guarantee it." Tony said, voice full of promises.

What had he just gotten himself into? Harry wondered.
