She was twenty-one; he was thirty-seven.

In his mind, he knew what he was doing was considered unprofessional at best and perverted at worst. She was a client and the daughter of a legendary lawyer whom he respected and looked up to. She was barely old enough to legally buy a drink, yet she sent shivers down his spine in a way that made him think very dirty thoughts and want to do very dirty things.

Business is best when mixed with pleasure, she would remind him as she placed delicate, barely-there kisses on his chest. Age is just a number, she would moan as her nails dug deep into his back.

He waged war against a major fast-fashion retailer for daring to rip off her mother's designs while she waged war against a pathetic ex who made it his mission to ruin her life just because she didn't want him anymore.

He emerged victorious, as per usual, bankrupting the company that had the nerve to steal from dozens of designers.

She had the satisfaction of seeing her ex's face when she arrived with a new man was older, Harvard Law educated, and oozed sophistication and class. He was everything the ex was not and could ever hope to be.

Her charm and wit gave him a legitimate run for his money and for a short time, he was dumbfounded. Then he was infatuated.

Once the sun went down and he finished racking up his billable hours for the day, he wanted nothing more than to hear her beg him to go faster in between hitched breaths. He liked when her eyes would flutter closed, her mouth slightly open but silent in ecstasy. She could be loud when she wanted to but it was nothing in comparison to when his name rolled off her tongue with a content sigh.

"Harvey."

Things got messier when his secretary intervened. She was always looking out what was best for him and Fucking Blair Waldorf definitely wasn't one of them. She told him to get his shit together and cut ties with the girl who's sixteen years his junior.

It didn't matter though because it all just felt too damn good.

A/N: Something that has been on my mind... It's not that long but I wanted to get it written down. I love Harvey and Blair is universally shippable so this was a no-brainer. Hope you enjoyed!
