About once a month, in fairly close times, the scent in Sabertooth's guild would change. Or rather, the scent of the women in the guild would change.
Sting wasn't stupid or oblivious. He knew enough about biology and humans to know why the scent of the women held a different air, and as such, he took precautions on those particular days to try to stay away from the guild, going out to train with Rogue and their exceeds or locking himself up in his room. It was for their and his own good. Under normal circumstances, he was fully in control of himself and none of their scents were strong enough to really bring the blood in his veins to a boil. But he still had dragon instincts and habits, and it wouldn't do to be in the guild when all of those scents pervaded his nose all at once and drove him towards desire. Better safe than sorry, even if he didn't find any of those scents particularly arousing.
Having developed an understanding of their monthly schedule around those shifting scents and knowing when most all of them started, Sting knew when to anticipate leaving. At first, depending on the amount of guild females ovulating all at once, he and Rogue would have to take a handful of days off every once in a while, but soon enough as time went on, the women pretty much lined up with each other that his off days were limited to two.
Except for one woman.
When Yukino finally came back to the guild several months later after she'd finished her work as a sergeant, it hadn't crossed Sting's mind that her cycle wasn't lined up with every other girls' because she hadn't been around for very long. It never really crossed his mind that he had to be cautious with her since she wasn't in the same cycle as the other girls. He'd just taken his day off with Rogue as usual, away from the women and in the peace of the mountains. Two weeks passed, and he paid no heed, his guard down and not being mindful of the possibility of someone being off the schedule he was used to.
But on this particular day, something was different.
He woke up with a raging boner—a painful one; something that embarrassed him to no end, especially when he had trouble dispelling it in the shower. His body wasn't listening, and his blood felt like it was on fire. He was hyperaware of everything. The cold water dripping down his back and forearms, every little sound, the brightness of the light. Sting knew as a dragon slayer and user of the magic, he had very acute senses and sensitivities that normal mages did not, but this went beyond his usual draconic peculiarities. Everything was too intense and no matter how much he tried to stroke away his erection, he couldn't reach completion. There was too much blood flowing straight south and he didn't know why.
Sting sniffed tentatively at the air, feeling weird and trying to figure out what it was in the guild that was fucking with his ability to carry out something that should have been a normal task.
Nothing stood out in particular as he pinpointed the various areas of the guild, until he caught wind of a scent. And not just any scent.
Yukino's.
It was pervasive and overpowering, and he could smell her as though she were in the shower with him, despite the fact that he knew she couldn't possibly be anywhere near him right now from the muted presence of her magic power.
But it was different somehow.
Yukino, under normal circumstances, smelled like lilies he liked to say. She had a sweet scent, a refreshing one that reminded him of flowers, one that made him wish he one day could bury his nose in her hair and inhale deeply.
But that day, it was ten times as strong, ten times as heady and the worst part was that it was mingled in with something almost carnal and wild and musty that sent a twitch to his cock and nearly floored him when a wave of heat crashed over him. Despite standing under freezing water, his entire body felt like it was on fire, his muscles tense and a strange pressure running through his body.
Her scent was caressing him like silk—addicting, arousing—stirring his loins. He closed his eyes, pressing his forehead against the shower, his breathing growing heavy as he pumped himself to rid himself of the build-up. It didn't take long to find release, especially with her scent so strong. He would be lying if he said he hadn't used her scent (or the image of her doe brown eyes and the tantalizing swell of her ample breasts and the smooth skin of her long legs) to get himself off before, but this time, it barely took any effort to pick it apart in the ass of Sabertooth guild members. It stuck out like a sore thumb, and he could pinpoint it directly regardless of who she was near.
Sting groaned in sheer bliss as he emptied himself, guiding his release by using her image, conjured easily by the fact that he'd engraved her face in his mind. It proved fruitful to find his release, but once he was done, he had a pretty damn good clue as to why her scent was suddenly permeating the entirety of his nose and senses.
Yukino was in heat.
And she was calling out to him to go find her. All he could think about was her sprawled on his bed underneath him, their naked limbs hopelessly tangled, her beautiful nude body glistening with sweat, her whimpers and moans in his ear as he…
He had to get the hell out of the guild and fast.
Faster than ever before, Sting got dressed and packed a small bag with some things he would need. He wrote a quick note to Lector that he'd be back in a day or two and that he needed some time alone and not to look for him. Usually on his days off, Sting wasn't so wound up that he needed privacy and could release his tensions by sparring with Rogue or relaxing in the hot spring in the mountain behind their guild, but for some reason, he wasn't anywhere near in a state to be around anybody, and he would have rather not subjected his Exceed to the second hand embarrassment of watching him struggle with a throbbing erection that wouldn't relax. No. This time, Sting needed privacy and lots of it to clear his mind among other things.
Rushing out of his room, a wave of Yukino's scent crashed into him again, stronger this time and clinging to his nostrils. It was beckoning to him—screaming really—and for a few seconds, Sting had to lean back against the wall, taking a few slow breaths to calm himself down when his heartbeat pounded loudly in his ears, his blood descending south once again. Maybe leaving his room when he wasn't altogether in control of himself had been a bad idea, but he had no choice. The longer he stayed, the worse (or better?) the intensity of the scent got.
Letting out a slow breath, he straightened and headed through the guild halls in a rush, not making eye contact with anyone and focusing his attention on getting out one step at a time.
"Master Sting. We have some more paperwork regarding the destruction of—"
"Not now," he growled, brushing past a member, his gaze intent on his destination out of the guild.
He didn't know what he must have looked like or what was on his face, but they must have sensed how tense he was because they stepped away with frightened expressions, leaving him be to go off. He nearly ran into Minerva rounding a corner, and she gave him a concerned look when she saw the expression on his face.
"You look flushed. Is everything—"
"Milady, I'm leaving for a few days. You're in charge," Sting ordered, ending the conversation and continuing to storm off before she could ask questions.
He had to get out of there. Yukino's allure was growing stronger. It was suffocating him. Every inch of every space was contaminated with that unbelievable aroma. It was too much and not enough at once, and Sting's vision temporarily swam as heat roared through his veins. He could hear his own heavy breathing through the blood pounding in his ears and for a second, an image of Yukino racing through the halls, trying to escape his clutches danced in his mind.
It excited him, this sudden desire to hunt her down. His senses prickling as he considered whether or not to turn around and find his prey. He could see it play out in front of him. She would run. He would give chase until she was exhausted, until she surrendered and then he'd get the chance to spread those luscious legs of hers and bury himself inside her tight warmth. He could already imagine her flushed face, her cheeks red and open mouth crying out in ecstasy as she clung to him desperately. He could take her more than once, watch her unravel in front of him—because of him—over and over.
She would be his.
Sting blinked, his eyes widening and breath coming out in short pants when he realized how close he had been to losing control of himself. He shook his head rapidly, trying to clear his thoughts from his sudden and intense desire to seek out his Yukino.
He had to leave the guild. Sting found it unbelievably hard to believe that all it took was just one woman to drive him nearly insane from her scent. It had to be a fluke. Sting was by no means completely educated on being a dragon, and a lot of living with those habits was trial and error and communicating with the other slayers going through the same thing, but at the least, he could surmise that the stronger and more difficult to control the desire to mate, the higher the likelihood that the object of attraction was the dragon's chosen mate.
Was Yukino his mate? Had he subconsciously chosen her without even realizing it?
It was strange concept to him, especially since he'd never considered or ever had the desire to procreate in his mind, but he supposed he was pretty much a dragon in his prime. And a human in his prime too. It could explain why he suddenly had an unbelievably intense, possessive itch to claim her as his and only his. Why he had this primal, overwhelming desire to fill her up with his seed. And why he had an overpowering urge to impregnate her.
It was like a switch had been turned on. A switch that awakened something dark and animalistic inside him that was wrestling his control away from him with each step he took away from Yukino. The farther he got, the harder it became to ignore the fire raging through his body. The craving he had to taste her, to claim her, to possess her. He wanted to chain her to his bed so no man could ever touch her or see her again.
His nose twitched when he smelled Yukino moving in the opposite direction from him. Every time he had seemed to pick up a fresh lead on where she was, the scent suddenly grew muddled or moved to a new location. She had been near Dobengal a few seconds ago. But now her scent was more concentrated in the guild hall where Orga was. And then it grew muddled again.
Sting's ears pricked, listening, concentrating for some kind of sound he associated with her. He could hear the soft jangle of her celestial keys as she ran. The unsteadiness of her breathing. The clacking of her sandals against the tiles. She was moving fast, heading away towards the east wing of the guild, definitely a far distance away from where Sting was. It almost seemed on purpose. Calculated.
He took a few test sniffs of the air, just barely catching the remnants of the trail of her scent as it briefly mixed with Rufus'. It smelled frantic. Almost flustered and a little panicked. There was another scent there. And that was when Sting realized he'd been concentrating on her scent so readily that he'd missed the other one that had been nearby her all morning.
Rogue.
Was he trying to help Yukino get away?
But above that, why was Rogue with Yukino when she was in heat?
Sting stopped walking abruptly and turned to face the interior of the guild hall, a low growl leaving his throat as a dangerous thought crossed his mind. If Rogue touched her, Sting would have no qualms tearing him to pieces for daring to put his hands on his mate. He still hadn't forgotten the incident where Rogue had groped Yukino.
It made his blood boil thinking about it.
No one touched her.
He stalked back through the guild, fists clenched and a dark irritation coursing through his body. If Yukino was trying to run from him, then by all means he would play the game and give chase. He would track her down and make sure that everyone knew who she belonged to.
She couldn't escape him. He'd find her wherever she went.
If either of them thought they could trick Sting by leading him on some wild goose chase through the guild to buy them time, they had another think coming.
"She's mine…" he chuckled darkly, licking his lips.
