Depending on reception. I have inklings of making this more than a one shot. So let me know what you think my loves!

One idea of how the 'sex spray' accident may have happened. And of course our yummy Yan is more than he appears.

ENJOY!

...

He was doing his best, but with a grown man attached to his side…

Said man practically humping his leg and not that he didn't enjoy it. Gods he really enjoyed it. Only his superior biology allowing him enough time to fight back the strange drug and get them somewhere safe. Ianto was panting, skin flushed with his need. Thank the Goddess they'd been the only ones there. No one else on his team was going to be affected.

Tirnelfs had been dying out. They must have created that spray to promote mating and eventual offspring.

Unfortunately, the canister had been mislabeled, Jack had startled him and the button had depressed. Spraying, the normally, quite reserved, archivist, in the face.

Jack found himself thrown over Jones's desk, being scented while a, quite large and most insistent hard on, pressed into his arse. "Yan?" Harkness sputtered, he was shirtless, when had that happened? There was a low growl in response, sharp teethe scruffed him. He groaned, sinking into the desk as his nipples were tweaked.

Ianto knew what was happening to him. He'd never expected it to happen though. Or to find a potential mate in Jack. He could have stopped it, let the drug wash over him, dissipate to nothing. He seemed to forget that Harkness must also have caught some of the spray. Then he'd smelled him. His eyes blew wide, his heart sped up, and his skin began to itch with want. He had to have him. Even if Jack didn't want him afterward. At least his hunger would finally be tempered. He could finally fuck the older man till he had his fill. He had a drug they could blame it on, if the match was not to be.

He was dry humping Jack, slowly realizing the older man was leading them to a hidden room. "Please, please sir I need…"

"I know Yan, just didn't want us being watched." Jack soothed.

Ianto was both relieved and saddened by the fact that Harkness was willingly going along with this, like it was a favor to the young man. Favor or not, he wasn't about to let Jack forget this. He let them fall to a bed and a fresh wave of pheromones hit Jones. He promptly stopped thinking and whined as he rocked into the Captain's palm. "It…It almost hurts. More Jack, please!"

"I'll make it better baby, promise." The older man cooed, quickly undoing Ianto's trousers. Giving them and his pants a swift yank. Fingers gripped in his hair as he swallowed the young man's cock. He couldn't help the moan as the tang of pre-cum, exploded, on his tongue. Or the grin, as his jaw stretched to accommodate the generous girth. Jones was well endowed, he himself, was a bit bigger, but only a bit.

"God, fuck yeah, Jack! Suck my fuckin cock!" Ianto near wailed as his control slipped for a moment, his hips starting to thrust. The older man took it in stride. Letting Jones, pretty much, use his mouth. Jack was happy to give his Archivist, the pleasure he seemed to desperately need. A few slurps and hums later, the young man was spilling down his throat.

Harkness wasn't to surprised when Ianto stayed hard. It seemed, he was going to get something out of this; as well. He knew Jones would be calling most of the shots, but it was hardly an issue. Secretly he enjoyed being dominated. Even better it was his normally reserved Archivist doing so.

"Trousers and pants off Jack! God I need to fuck you so bad." The younger man groaned, slowly stroking himself. The Captain undressed quickly and scrambled up the bed. Without warning he was pushed back to the pillows. Ianto's tongue dragging down his neck. "Fuck! Taste as good as you smell, Jack."

The older man moaned low. Turning his head, offering more of his throat. Suddenly, glaringly aware of the fact, he wasn't going to be happy with, just one sex gas induced encounter, between them. No matter how satisfying the sex would be. He could no longer think of Jones as a mere fling possibility, an itch to be scratched. As much as the Archivist could smell him. Well that went both ways. He realized, the reason he was submitting so easily, was because Ianto was an Alpha. His Omega was reacting to the scent, quite happily in fact.

Jones startled himself when he snarled. Startled even more when Harkness responded with a whine and a little wiggle. "Even if you don't, your body understands doesn't it?" He growled, shifting enough that soft fur with stripes appeared and Jack mewed as a longer, slightly rougher, tongue circled his nipples. "I can't hold back much longer Jack. You deserve to know. If we fuck, I will mark you as my mate right here in this bed." Ianto sighed. He had really, really wanted to fuck Harkness before the inevitable rejection. His conscience had won out however, and he just couldn't go through with it. Knowing he wouldn't be able to control himself. His body was screaming at him. It really was quite painful to, suddenly ignore, the mating urge; once you had let it take you.

Harkness, found it in himself to move. He ended up on his knees, whimpering as he shook his bum, begging. "Yan stop hurting yourself, mount me, mate me, just fuck me please!" The older man pleaded. His yelp ending in a groan as Ianto lifted his hips and impaled him. Jack let out a low whine, feeling owned, but finally protected and safe.

"You're mine Jack, Mine!" Ianto hissed, but not unkindly. Punctuating his words with sharp thrusts. Harkness mewed again, a keening starting to sound as he, eagerly, pressed back into his mate's rhythm. "I'll protect you cariad. You're mine and I'll take care of you." Jones murmured, laying across the Captain's back, reaching down to fist his older lover's neglected cock. A few strokes, was all it took and Jack was coming across the bed. Ianto however, only slowed enough to manipulate his mate. Soon the Captain was on his back again, his Archivist come lover, was currently pushing his legs up and out. To achieve deeper penetration and closeness.

Harkness watched the rough tongue slide over gleaming fangs and shivered in anticipation. Ianto thrust hard, curling his body over Jack, as his pointed teethe sank into the crook of the older man's neck. "Mine!" Jones snarled. Losing what control he had, upping his pace till his mate was screaming his release.

Ianto followed with a roar and the Captain was entranced by blue pools that seemed to glow. "Gods a real Lynxian, They're supposed to be extinct…and you're mine?"

"Always Jack, our lifespans match our mate's" Jones purred as he nuzzled the mating mark, fully shifting and resting a golden paw over his Captain.

Harkness gladly snuggled. Knowing they would talk more later. He had a, pretty big kitty, snoozing on his chest and he wasn't going to disturb it unless he had to. He knew better. Only fools disturbed, a contently sleeping, Lynxian. Very few, of said fools, lived to tell about it. Didn't they know?

Kitties got claws!
