Author's Note: Had the desire to create a Coldflash A/B/O, and figured, why not make a complete AU while I was at it? Enjoy!

Barry entered an office and closed the door behind himself before settling in front of Leonard Snart's desk, aware that the businessman's eyes were flicking over him curiously. The younger man took an inaudible deep breath, fighting against his natural reaction to the older man. "I didn't think you'd agree to see me," he murmured.

"Then why try to make an appointment?" he drawled amused.

Barry licked his lips and locked gazes with the older man. "However I say this will sound grasping or weird, so I'll just come out with it okay?" His companion nodded. "I was on the treadmill, and had the news on," he stated. "I wasn't watching it, and it went to a quote from you, and just your voice made me wet," he stated.

"I hope you weren't at the gym?" he asked concerned.

"No, I have one at home," he assured quickly. He licked his lips. "I'd never had that happen before," he stated. "I'd become slick when I was with someone I was attracted to, but never just from a person's voice, without even seeing what they look like. I knew that it meant we're compatible," he added in a rush. He averted his gaze. "Like I said, I didn't think you'd see me, and if by a longshot you did, I didn't think you would be interested, but I had to at least try."

"Look at me Barry," he compelled, and the omega's gaze immediately shot to his. "You are adorable, and any man, alpha or beta, would be lucky to have you," he stated firmly. Barry's lips curved up, even as he blushed. "Come here," he urged, holding a hand out to the younger man. "I haven't dated anyone as young as you since I was that young myself," he remarked as the younger man rose, "however, you are exactly the type I go for."

"Cute?" he asked as he rounded the desk.

"Being attractive doesn't hurt, but I meant a runner's build," he corrected gently. He smirked as his scent hit the omega, causing him to shiver. Barry took his hand, and he spotted the bulge the older man was sporting. His blush intensified. "I gained this the moment you came in the room," he informed the omega with a wicked smirk.

"You did?" he asked licking his lips.

"I never lie," he stated, squeezing the younger man's fingers. "I mislead with the best of them, but I never outright lie." Barry nodded as he absorbed that. "I take it you don't have a lover?" The younger man shook his head fiercely. "Good, and I'm free to enter into a relationship too," he stated. "But I suppose the real question is, what do you want from this Barry?" The younger man's gaze flew to his, startled. "I will not mate or knot you without your express permission beforehand," he spoke firmly. "Are you just looking for some fun, or for something permanent?" Barry licked his lips. "Be honest with me," he urged firmly, carefully ensuring he didn't make it an order.

"We hardly know each other, but I really want something permanent," he answered breathily.

He tugged the younger man onto his lap, smirking as the brunet gripped his shoulders instinctively. "Good," he drawled, smirk widening at the younger man's shiver. "The basest part of ourselves knows we're compatible," he purred, "the rest is just window dressing."

"But Leonard-"

"Len," he interrupted, before laying a finger over the younger man's lips. He pressed the intercom with his free hand. "Deborah?"

"Yes Mr Snart?" she answered dutifully.

"Clear the rest of my afternoon."

"Of course Sir."

"And I'm not to be disturbed," he added, grinning wickedly at Barry's shiver.

"Understood Sir," she replied and he lifted his finger off of the button.

"Now, how about we get to know each other?"

"If you mean talking, I'm going to need some space," he panted.

Len chuckled wickedly. "Are you wet Barry?" he purred. As the younger man bit his bottom lip, Len's hand drifted to the base of his back. "If I checked, would I find a damp patch?" he purred, grinning as his companion blushed. "Are you untouched Barry?" he asked softly.

"Yes," he admitted.

Len lifted the omega and set him gently upon his desk. Barry blinked, startled. "Perhaps we had better talk first," he spoke with a sigh. "I wouldn't want you to regret rushing into anything."

"If-"

He placed a gentle finger over the younger man's mouth, stilling his words. "It's not a reflection on you being inexperienced," he spoke firmly. "If anything, I find that thought alluring," he stated. Barry's lips curved upward. "It's me that needs the space at the moment," he continued, "before I let my possessive instincts overtake all the others." He lifted his finger.

"Okay," he breathed, and began talking fast. "I'm an only child, my Dad's a doctor and my Mum's a real estate agent. I graduated from CCU with a degree in sciences with a minor in business."

"Business?" he repeated, interested.

"I was thinking of working in a research company of some description, and figured having working knowledge of budgets and profit ratios would only help me get my hands on funding," he admitted with a shrug. "And when I say sciences, I mean that my degree covered courses on all of them. It was mostly focussed on physics and chemistry, but there was some basic biology covered too."

"Not too much free time then?"

He shook his head. "My attempts at dating were rather disastrous, so after the first couple of semesters, I just focussed on my studies, and I graduated with top honours," he stated with a pleased grin. "I don't have a job yet," he stated, "but I've made several applications."

"That works out well," Len murmured. Barry's eyebrows rose. "I'm sure you know enough about me to know my company has interests in a variety of fields." The omega nodded. "I've been thinking about opening a new branch of my R + D department, a science division, but of course I would need someone who not only understood the science, but was able to tell if their proposed time scales and budgets are feasible."

"You'd hire me?" Barry breathed. "And not just out of-" he cut himself off.

"If you had walked in this office and given me your résumé, I would have instantly considered you for this position, however," he continued before his companion could get too excited, "it isn't just down to me. Hiring is shared between myself and my partner." His companion drooped a little. "Get me your résumé, including references, and I'll flag it and send it to my partner."

"What does flagging it mean to you?" he asked curiously.

"Both of us do it, it means we like this candidate for a specific position, and want the other to decide if they can see any reason not to."

"You don't think I'm too young?"

"Age means little here, only skillset," he stated. "We've got employees across the spectrum of ages, from those only just eighteen, all the way to past retirement age," he continued proudly. "We are in no way ageist, and if someone has the specific skillset we're after, we're willing to overlook a lack of experience. After all, how will you gain it, if no one gives you the chance?"

"Okay, first I need to say, that I didn't come in here looking for a job, or-" he cut off with a blush.

"With the idea of using your wiles to gain one?" Len suggested with an amused smirk.

He nodded, blush intensifying. "But, if you'd consider me, I would be interested," he spoke. He licked his lips. "Did you want to date a little first?" he asked shyly.

"Honestly?" he drawled. The younger man nodded. "I want to bend you over my desk and mate you, before knotting you," he stated with heat, lips curving as the younger man shivered. "But if you want to date first, I'm willing to do that."

Barry climbed back onto his lap. "I want what you want," he breathed, burying his face into the older man's neck and breathing in his scent. He let out a soft moan. "I want you in me so bad Len," he spoke with a hint of a whine. "I want to feel your knot in me," he panted, pressing his pelvis against the older man's, the feel of the alpha's cock against his own making him moan, even through their clothes.

"Temptation," he purred, gently pulling the omega back enough to claim his mouth in a heated kiss the brunet eagerly responded to. He pulled back panting hard. "Let's get you naked, hmm?"

Barry stood and kicked off his shoes as Len tugged his top over his head. He bent to pull off his socks, and found his face level with the alpha's bulge. He licked his lips. "Next time," Len promised, a gentle hand urging the brunet upright. "I want to be in you too badly for that."

Barry shivered and dropped his hands to his waistband, undoing the button and zipper quickly, and pushing his jeans down his legs. He blushed as his hands went to the waistband of his boxers, but he pushed them down too until he stood naked in front of the alpha.

"Perfect," Len purred, as his eyes took in every inch of the omega.

"Do I get to see you?" Barry breathed.

With a smirk, Len rose and stripped in economic movements, which widened at the moan he received from his pretty omega. "Thank you for the compliment, temptation," he drawled, dipping his head for another kiss, this one full of promise.

He pulled back at his pretty omega's moan, his lips curved in a smug smile. "Bend over the desk for me," he urged.

"Are you always like this?" Barry asked curiously as he complied.

"Like what?" he replied almost absently as he took in the sight of his pretty omega spread out before him.

"Not giving orders?" he asked, shifting enough so that he could look at the alpha over his shoulder.

Len paused, his gaze going to Barry's curious one. "Just because I'm an alpha, does not mean that I should impose my will upon others," he spoke firmly. "I ask, I request, I urge, and others comply because they see the sense in the proposed action, not because they have no choice in the matter."

Barry's smile was bright. "I like the sound of that."

"Eyes forward," he urged. "I don't want you to get a crick in your neck." Another smile from the pretty omega before he complied. The alpha's gaze slid down to the omega's slick entrance. "You are wet for me," he drawled, and slid two fingers into his omega's unresisting hole.

"Len," he gasped.

He pulled them out, bringing them to his mouth, and watched avidly as the brunet's hole clenched on air. A soft whine from the omega. "You taste delicious Barry," he purred, leaning down and bracketing the pretty omega with his body, causing him to shiver. "I want to part the cheeks of your pretty ass and lick you all up," he drawled, his voice a rough purr. "I bet I can get you to flood my mouth with more of your slick before I'm done."

The younger man let out another whine. "Another time," he promised. "Please, Len, I want you in me."

"Next time I'll get you to be more specific," he stated as he withdrew enough to line the head of his cock against his pretty omega's entrance. "But since I got you into this state, I'll give you what you want," he continued in a rough purr and shifted his hips, pressing into his pretty omega in a slick slide that had them both groaning.

Len paused as he was fully sheathed, giving his pretty omega the time to get used to it. "Len," he whined, "please move."

"Whatever you want, temptation," he purred, gripping his pretty omega's hips possessively as he shifted his hips, setting a steady rhythm – enough to satisfy, but not to injure. He wanted to ensure that Barry enjoyed this interaction thoroughly, and was eager to get together another time.

Moans tumbled from Barry's lips at the feel of Len filling him up with his long, thick cock, his pleasure rocketing higher with every thrust until he felt he'd explode if he didn't cum soon. He let out a needy whine. "Shh, Barry, I've got you," Len soothed, one hand shifting under his pretty omega to wrap around his hard, weeping cock. He stroked in time with his thrusts, drinking in the pretty moans that fell from the younger man's lips, and shifted his hips just right so he brushed Barry's prostate as he thrust deep.

"Len!" he gasped as he came, clenching hard around the alpha.

Len gently eased his omega upright, smiling when the younger man leant back against him. "You didn't knot me," he panted, lips shifting into a pout.

Len chuckled softly. "Call me old-fashioned, but I prefer to knot my partner after I've mated with them," he responded lightly.

"I thought you were going to do that too," he spoke in a soft voice.

Len tilted the younger man's chin gently until their gazes met. "I have every intention of doing both, Barry, as long as that is what you want," he spoke firmly.

Barry licked his lips. "Then why-"

"Because you deserve better than to be mated over a desk," he drawled. Barry blushed. "And don't you want to tell our future kids a better story than that?" he teased.

He licked his lips. "I suppose," he murmured. He shifted so that he faced Len, head tilted curiously as he looked up at the older man. "What did you have in mind?"

Len's lips curved. "Dinner, then take you back to my place for dessert," he drawled.

Barry shivered. "Okay," he murmured.

Len cupped his cheek gently. "And it'll give us the chance to know each other a little more," he added, stroking a thumb over the younger man's cheek. Barry licked his lips and Len ducked his head, claiming his pretty omega's mouth in a kiss he eagerly responded to. "Better keep that gesture to a minimum, temptation," he warned.

"Is it really that tempting?" he breathed.

Len smirked, eyes heated. "Do you really want me to answer that?"

He cleared his throat softly. "Shall we go to dinner?" he asked breathily.

Another chuckle from Len. "Better get dressed first," he retorted, causing his pretty omega to blush. "I'll do my best to keep my hands to myself, at least until we're in private."

Barry leant up and kissed Len sweetly. "Looking forward to it," he stated, before ducking his head with a blush.

Len watched Barry dress with a smile, feeling on the basest level that this pretty, prone to blushing, omega was perfect for him, and knowing unquestionably that he had been worth the wait.
