AN: Finally a prompt at the right day LOL

#

heat = intensity, as of passion, emotion, color, appearance, or effect

The white Wolf was thrown to the ground, where it whined as the black Wolf – Gray Fullbuster in his animal form – growled and bared his sharp teeth to the man in animal form underneath him, now bowing its head down in submission. With a final growl, Gray returned to be human and so did the other man, Lyon Vastia.

Gray waited for the words; otherwise he would need to keep fighting Lyon until he was unconscious, because there couldn't be two winners, not in that fight.

"You won." Lyon coughed, trying to breathe and putting a hand over his ribcage in pain – the other man had given him a run for his money and had literally fought with teeth and claws to win.

Hearing a growl of delight, Lyon saw Gray's eyes snap towards the trees, where the prize was: blue hair loose, eyes wide as she watched the fight with interest.

Lyon had arrived a couple of hours before and after a few minutes the man knew that Juvia Lockser was going to enter her heating cycle soon by the way her scent got stronger; the white haired man knew that Gray still hadn't made his move on the Omega woman and being an Alpha, Lyon certainly had his shot on getting Juvia Lockser.

When he tried to make a move on the woman, though, Gray stepped on the way as if daring Lyon to do anything and the white haired man raised an eyebrow with the reaction, but as they clearly hadn't started anything plus the fact that she smelled strong and delicious, made Lyon lose his mind and demanded that Gray stepped out of the way so he could try his luck with Juvia.

Gray didn't bulge from his spot and Lyon asked if the other man would like to be challenged in a duel to get the female Wolf, otherwise Gray should just step aside and let him try to hit off with Juvia. The dark haired man narrowed his eyes and looked over his shoulder, to the woman in question and there was no doubt that she was getting in an early heat (usually she would spend the week of heat alone in her apartment but if she was around males whom she thought was attractive, her body would try its best to find a mate by entering an early heat to tease them) and at the moment there were two males whom she thought were attractive and verbally fighting for her, Omegas always loved that.

Hating the thought of letting Lyon having Juvia in any way made Gray accept the challenge right away and Gray had won.

Lyon saw his opponent run towards where Juvia stood and coughed, triggering pain on his chest. He was so stupid to try and get in the middle of them when he knew that Gray was just denying his attraction to the woman and if set off, he would face his feelings; apparently Lyon had done exactly that.

#

Juvia watched the fight as it finished – it was easy to identify each Wolf, since one was white and the other was black, but the whole dispute was a big blur of gray as they fought – her whole body got hotter as she saw that the winner was her Gray-sama. If it was Lyon, she would decline his advances, but with Gray? Whatever he wanted to do, she would oblige and when he looked in her direction, his eyes were dark and he seemed more animal than man, and the way of his body language indicated that he fully intended to reclaim his prize.

When he stepped towards her, she immediately stepped back and Gray frowned lightly as he gave another step and the woman stepped back once again.

She wanted to have The Run with him; she wondered if he would run after her as the old costume say, to catch her and prove that he was worthy of her. Her mind had certainty that she loved Gray and wanted him with her forever, but the Wolves had an entirely different way of doing things; Gray fought for her and won and that made him prove himself to be the one to have the opportunity to have the Run, to put his pups inside her, but now he had to prove to her Wolf that he could catch her.

Noticing her intention after a moment, Gray moved to a position to prepare himself to run, making Juvia feel another rush of heat go through her veins. Juvia smiled in excitement and turned towards the woods and run as fast as her feet could take her; the blue haired woman could hear him coming right behind and not too far away, but she couldn't slow down until Gray caught her otherwise it wouldn't please the Wolf inside either of them, so, she ran until it hurt.

A few minutes after they started to run, Juvia looked over her shoulder to see where Gray was and wasn't surprised to see him only a few meters away and the Wolf howled in delight and it started to use her senses to find the best place for him to get her.

'Left. Go left. It is the best place for Mate to get us. Near water. We like water.' The Wolf told Juvia inside her mind and the woman did exactly what was suggested, turning left and felt a gush of air as Gray tried to get her but failed as she turned away unexpectedly. The man groaned in frustration and Juvia's laugh echoed through the woods as she kept running – even if she wanted to get this over with already and feel him ease her heat, she had to run to make it interesting for him.

She managed to run a few meters before the man finally caught up to her, grabbed her by the waist and he threw himself on the ground, turning around so he was the one with his back on the ground ('Good Mate doesn't want us to get hurt. Nice Mate. Sweet Mate.' The Wolf told Juvia and the woman agreed with it). The blunette tried to get free of his arms – she didn't really want to, but for the Run to be successful the male needed to subdue the female as she tried to fight him off to show to the male's Wolf that she could protect any pups they would have, but Gray was having none of it by turning their roles and pressed her on the ground with his own body on top of hers.

She tried to get free from underneath him one more time by pushing him away by punching his chest with her tiny fists, but the man grabbed her hands, more annoyed with her than hurt.

"I caught you." Gray snarled. "You don't need to keep fighting me, the Wolf is satisfied with your Run and the struggle; just say the words." He almost whined in frustration as she finally stopped squirming. "Please, say the words."

Juvia bit her lower lip, feeling the want for him rise once more. "You got me, Gray-sama." Before she could finish the last word, his lips were on hers and it was like her whole body turned into fire and she was being consumed by it.

One of Gray's hands went to her hip and pulled her shirt up to touch the soft skin of her stomach and she whined in frustration; she had wanted him that way for so long and she finally had him – she expected their first time to be in a bed, not during a Run Ceremony, where they would most likely Bond for life after, not that she was complaining, it was turning to be better than she thought it would.

"Do you accept my claim?" Gray asked between kisses as he undid his pants before undo hers – thankfully their clothes magically appeared when they returned to their human forms.

"Yes." Juvia gasped and pulled him down to kiss him again; the ceremony was just beginning.

Juvia walked to the stream which was close to where they completed the ceremony like her Wolf told her it would and it was a great place to bond with her Mate.

Her Mate. Juvia chuckled as she cleaned herself (mating on the ground wasn't exactly the best to be clean, but it was lots of fun) and tried her best to clean her hair, otherwise going home looking all dirty would raise some eyebrows.

"Our clothes are a mess." Gray said as he joined her at the stream and put an arm around her waist and nuzzling her neck kissing the bite mark he left on her minutes earlier. "People will think we were in a mud fight."

"In a sense, we were…" The woman smirked and he laughed, face still buried on her neck.

"I guess." He said and saw her turn around to him, wrapping her arms around his neck. "I can't believe that we just Bonded."

"Me too. My Wolf asked me to tell you that you are a very good mate." Juvia smiled at him with mischief.

"Oh. Thanks." The man blushed and she chuckled. "I kind of lost it after winning against Lyon. I still can't believe that he was stupid enough to challenge me for you; he knew very well that I wouldn't let him get you. And my Wolf was not too much help by keep telling me to get you and when you wanted to Run, I couldn't say 'no' and the way you smelled… Was that an Early Heat? You usually lock yourself in your apartment when it is close."

'Smart Mate.' Her Wolf howled and Juvia agreed.

"Yes." The blunette sighed. "It was unexpected, usually Juvia knows the signs and prepares, but you and Lyon are both compatible to Juvia and it triggered an early Heat."

Gray growled when the woman mentioned the compatibility she had with Lyon and kissed her deeply just like he did minutes before. When they parted, he informed: "We will get to my place for the next days until your heat cycle is over and you won't even think Lyon's name, even though he is about 1% of the reason to why we are together right now, alright?"

Juvia was surprised. "Are we?"

"Are we what?" The man was confused.

"Together. Are we together?"

Gray rolled his eyes. "Well, we just bonded for life, I kind of thought you got the hint. Now let's go home."
