Hey, its been awhile since I updated so if your still with this story sorry!! Hope to get more chapters up soon. Please review :)

Izzie Stevens had modelled for years but even now, even after numerous photo shoots in various outfits she still felt ridiculous posing seductively on a bed. She was wearing new black lacy lingerie, suspenders and black stockings but she still felt stupid. No matter how many photographers and assistants told her she looked fabulous and sexy she never believed them.

Right now she was taken back to all her years off modelling, but this time she was not surrounded by photographers and makeup artists calming her nervous, right now she was lying on Mark Sloan's bed with a plate of strawberries and a bottle of champagne chilling on his night stand.

Izzie hoped this was not a mistake. Mark should be home soon and seen as she had been already waiting for him for an hour Izzie was distracting herself by flicking through a magazine. Izzie was pretty sure Mark would love her waiting for him and she would make sure that he would enjoy what followed but god right now she did not feel confident or sexy.

Maybe Mark would not want to see her tonight, maybe he was going to go to Joe's and pick up some random girl. He was Mark Sloan after all and Izzie was sure that on nights when he was not with her he would be with some other woman. And the great thing was she did not care, but she would care if he arrived home with some girl on his arm. All of a sudden Izzie was panicking. She should never have done this; anytime they had sex it was always arranged.

Izzie jumped as her phone alerted her that she had just received a text, grabbing it out of her bag she saw it was from Mark. He was in Joe's and wanted to see her later. She replied telling him she'd see him in half an hour at his hotel. Putting her phone back in her bag Izzie returned to her position on the bed and continued to read her magazine. Now she felt safe knowing Mark would not bring some girl from Joe's back she returned to feeling stupid for posing in her underwear.

Mark had a long, horrible day. And on top of everything today he was another year older and nothing to show for it. He was in his late thirties and had a crush on Lexie Grey. He was a man in his late thirties who acted like a teenage boy around the young intern. It was embarrassing and humiliating. He had spent his day with her on his service and every moment of it was uncomfortable and awkward for him, but Lexie did not even notice him. If he was not her boss she would never even look at him because Lexie has eyes only for George.

At least he had Izzie to make him feel like an actual grown up man. But it had been Izzie's day off so he had not seen her since this morning. As he was finally leaving the hospital Callie grabbed him and dragged him to Joe's with her, Erica and Cristina. She wouldn't let him just go home and sleep on his birthday and despite all his protests she finally got him to Joe's.

Mark hated celebrating his birthday, his family barely acknowledged it anymore. Growing up his birthday was a huge event. All of his mothers friends threw big parties for their children's birthdays so Caroline Sloan did the same for her son's birthday. Each year Caroline was on a mission to make Marks party the envy of all her friend. Guests would tell her what an amazing mother she was to throw such outstanding parties but Mark hated them. And as Caroline Sloan inflated her ego Mark grew to hate his birthday. Today he had received a brief call from his mother.

Going to Joe's cheered him up. Scotch certainly took the edge off the day. He chatted to his co-workers but his mind kept wandering back to Izzie. He really wanted her company tonight and he was surprised he had not heard from her all day. He had seen her briefly this morning while talking to Derek and she knew it was his birthday, surely she want to give him birthday sex?

Mark began to wonder if Izzie was starting to get bored with their arrangement. Maybe she was dating some other guy, or maybe she was beginning to forgive Alex. Mark grabbed his phone and quickly sent a text to her wondering if she would stop by tonight. Smiling when he received a reply he finished off his drink and said bye to the girls.

Relief had flooded his body when he had received Izzie's text. He could not wait to see her. Maybe he was becoming to reliant on her but right now he did not care. Walking in to the hotel he could not wait to see Izzie, to hold her, kiss her and have amazing sex with her. That's all he wanted for his birthday. In the lift he decided he would grab a quick shower before Izzie would arrive.

His plans soon changed as he opened the door to his hotel room. Lying on his bed was his favourite lingerie model, wearing stilettos, stockings and black lace. Mark realised he finally had a reason to like birthdays.
