Author's Note: The first time I had a request for a threesome with these characters, I was able to sort of avoid them actually doing the deed. This request specifically asked for smut, so I did my best in trying to make it more than just a threesome fic. I hope I managed to do okay. All errors are mine. Let me know what you think.

Mark Sloan likened his conscience to a cold-inconvenient, annoying, and dangerous to his well-being. He rarely thought twice about his actions and it suited him well. He was a believer that sometimes it was right to do the wrong thing, and it was usually on those occasions that he had the most fun. Mark was all about fun, or so he thought.

Now, as Callie Torres pulled down Addison Montgomery’s underwear with her teeth, Mark’s conscience decided to make its presence known.

No. He refused to feel guilty about this. He and Lexie were on a break (their fifth in the entire span of their on-again-off-again relationship). Callie and Addison were both unattached. They were consenting adults and were far from inebriated. The doctors were all of sound mind and shared a common desire: hot, sweaty sex. It seemed as though the fates had aligned for the three of them to end up in the same city on the same weekend at the same medical conference. It was as if God Himself had shone His holy light upon him and said, “Go forth and fornicate with these willing wanton goddesses.” Who was he to ignore a holy quest?

A burning in his gut boiled unpleasantly as he came behind Addison and sucked her earlobe into his mouth. He knew this was a bad idea but he’d be damned if he’d pass up a threesome with two of the sexiest women he’d ever fucked.

Callie kissed Addison with vigor, their tongues swirling and laving at each other while Mark watched with eager eyes. His dick throbbed mercilessly and he thanked heaven that his conscience hadn’t effected his arousal.

What was the big deal? So he was going to spend a night banging two exes? He was clean, had condoms-he was the epitome of a responsible adult. So why did he feel so wrong when Addison reached behind and curled her fist around his dick?

He thought of Lexie back in Seattle. He thought of his struggle to grow the fuck up and stop acting like a horny teenager. He thought of his daughter and his grandson.

He thought of Callie, who had just dropped to her knees in front of Addison and was nuzzling the tuft of red hair nestled between her thighs. He let out a little groan at the sight of it and planted his feet into the plush carpet of the hotel suite, allowing Addison to lean her long, lithe body against him for support while Callie began to eat her out. Ever the helpful participant, Mark palmed Addie’s small breasts and teased her nipples, realizing for the first time in years how much he had missed them. He missed her or, rather, the idea of her.

Yeah, it was one hell of a bad idea to get mixed up with exes, but Mark wasn’t backing down. He was a fuckin’ man--he could handle a little guilt. What was a giant leap backwards amongst a series of strides forward?

His train of thought halted when Addison’s fist began to steadily pump along his cock, squeezing every time Callie’s tongue flicked across her clit. He licked his lips, recalling the taste of her, and wondered if he’d have the opportunity to go down on them both at some point in the evening.

Addison began to moan and arch her back. She coiled her free hand through Callie’s hair and when she came only minutes into the encounter, it was with a howl that sounded almost painful. It sounded as though she hadn’t come like that, or maybe at all, in ages. Mark could almost convince himself that he was doing her a favor. If anything, he was being a damned good Samaritan.

When Callie stood with more grace than should be possible for a woman who’d just expertly muff dived, she pressed a peck on Addison’s lips before leaning over her shoulder to kiss Mark on the mouth. He hungrily sought the taste of Addison’s wetness on her tongue and grunted.

He pulled away and watched as they got onto the bed, settling themselves so that Addison was knelt between Callie’s legs. The women kissed with such hunger that Mark half-believed that he could leave the hotel room without being noticed. His eyes shot to his pants, crumpled on the floor a few feet away.

He thought once more about Lexie, who might very well be thinking about him. He wondered if he should call her despite their break. He missed her with an ache that was still unfamiliar to him and as he gave serious consideration to leaving before it was too late, Addison looked at him over her shoulder and wiggled her naked hips enticingly.

Mark’s throat suddenly went dry. Her swollen folds glistened with arousal and his cock twitched at the vision of it. He stepped forward, almost propelled by the greedy hunger of his insatiable sexual appetite. He knelt behind her and pressed his hands to her hips. His hips quivered slightly, desperate to drive himself forward into Addie’s warm, wet depth.

He looked down at Callie, whose face was awash with pleasure while Addison fucked her with her mouth. She opened her eyes long enough to catch Mark’s gaze. She grinned and gave him a wink. “Best…conference…oh!...ever…” she muttered through her moans, and then her eyes clamped firmly shut as Addison drove several fingers deep within Callie’s core.

Mark remembered the last fight he’d had with Lexie. He remembered her spiteful words. He remembered the tears that she refused to shed and the way she slammed the door in his face. He also remembered holding her at night, and sharing the last bowl of Cheerios, and the way she smiled when he said something idiotic. His conscience fought to hold him to these thoughts even as his fingers dug into Addison’s pliant hips.

He could smell the heady, intoxicating scent of their combined arousals. Every fiber of his being that made him the scoundrel he had formerly been awoke and pushed aside his reformed self. He gulped and decided that his conscience could fuck off. He drove himself hard inside of her, forcing her to cry his name. He’d missed the way it rolled off her tongue and repeated the motion just so he could hear it again.

He fucked Addison with vigor, pistoning his hips in quick, steady strokes that made it impossible to think about anything but how fucking tight she was. He snaked his hand around her waist and teased her clit, all the while watching the way Addison tongue lapped between Callie’s legs.

Without warning, Addison came, clenching hard against him. She muffled her shrieks of pleasure in Callie’s cunt, pausing her own ministrations as she rode each wave of her climax. Mark could feel his own orgasm building and struggled to avoid losing it too soon. Addison helpfully released him and shifted on the bed, ignoring Callie’s disappointed pout so that she could allow him to move in between Callie’s thighs. She eagerly wrapped her legs around his waist and lifted her hips to meet his dick as it surged forward.

Mark let out a low moan at the tight feel of her and began to fuck her with little thought for the situation itself. He felt above himself, far away from the body that was giving it to his ex-girlfriends. It was from a different vantage point that he watched Addison stroke Callie’s clit and kiss her breasts.

His climax hit just after Callie’s. She writhed and bucked and moaned; he drained his balls inside her and threw his head back, closing his eyes hard against what was displayed before him.

He couldn’t pull away fast enough. He discarded the condom and all but jumped into his pants, yearning to get under the cleansing spray of a scalding shower.

Sated and delighted with their naughty romp, Addison and Callie attempted to persuade him to stay. They tempted him with promises of blow jobs and anal sex, but Mark dressed quickly, kissed them both, and said his goodbyes. When he shut the door of the hotel room, he knew he’d left the remainder of his former self behind.

Mark got lost on the way back to his own room. He couldn’t remember which floor he was on and took the elevator two floors above where he was meant to be. It didn’t surprise him in the slightest; everything about the night felt wrong.

He cursed himself for falling so far from the path he’d set for himself, and for what? Forty-five minutes of sex?

Mark let himself into his room and, neglecting the light, sat in the dark on the bed. He thought again of Lexie. He missed her and he hated himself. Once again, he’d proven to himself and everyone else that he was a dog. He was the same guy that everyone thought him to be, despite how hard he’d tried to change his ways. What was the point of fighting it anymore? He was a product of the all the choices he’d ever made, and tonight only proved that he, Mark Sloan, was neither a smart guy nor a good guy.
