Summary: A Beta mechanic is one thing. Dealing with a Beta mechanic when you're dealing with your heat and needing to rely on him, is an another thing Castiel wasn't ready for.

…...

There was only one thing that was his fault, Castiel decided as he shrunk down into the corner of the almost empty garage. It wasn't making the Beta mad, no, he was already angry at the Alphas who were tormenting him, earlier, and Castiel of course had to come in at the wrong time.

The only wrong time in his entire life which he forgot his heat depressants, and his damned hormones decided that it was a good time to kick in. He had simply made a schedule to have his car looked at, brought it in right at the moment when two Alpha strangers were bothering the part-time owner of the shop, a greasy Beta named Dean, who boldly told them off.

The man was friendly towards Castiel after the whole ordeal, although his eyes were still flaring because of the Alphas. So it had come to this, an overly handsome Beta was working on Castiel's car while the hormones of his had kicked in, leading him to shrink in the corner and hide himself, hoping the car would get fixed soon so he could hurry and leave without Dean smelling him.

He knew the Beta was working his anger from earlier from the stress on his car. Loud noises and cursing and small talk to mask the apologies to Castiel were coming from nobody but Dean.

"Hey man, are you okay? Why are you shrunk up against the wall like that?" Dean took a break from the tan Lincoln to look at Castiel with worry. Castiel looked away, trying to hide as much embarrassment as he could. It wasn't Dean's fault that his heat decided to throw a parade two weeks early.

"...My heat just started." Castiel admitted, causing whatever tool Dean had in his hand, to drop.

"Dude, do you need to go to the hospital? Like your car is mostly fine it's just a little oil leak-Shit!" Dean exclaimed as Castiel hugged himself and whimpered, the fire in his belly was now consuming his entire being. He had to admit, this heat was much worser somehow than his others, it was confusing and scary.

"Damn, you smell good." Dean snarled.

"Just...take care of it." Castiel rasped, feeling guilty of what he was about to do, yet he felt like it was too late for a hospital, besides all the Betas and Alphas would be trying to make their own claim onto him before he could even think of being taken care of. He could almost laugh if his skin wasn't feeling on fire and his need was clawing at his every whim to submit, he was going to have sex in a stranger's garage for the first time.

Dean hastily closed the garage door, not willing others to smell the distressed Omega in heat.

Dean was at a stalemate. He didn't want to take advantage of the Omega, he detested the thought. However he didn't really have much options, Omegas were more rare than Alphas and Betas, and not many people didn't know what to do in a situation like this. Dean for sure didn't, all he knew was from Sam telling him that heats could last from four to seven days, a conversation between the two brothers happened like, seven years ago.

Right now the intoxicating smell of Cas was hitting him so hard, it was hard to think. The trench coat clad man with the terrible car was smelling finely of honey, crisp autumn air, and sea salt. It was intoxicating and Dean felt relieved for once that he wasn't an Alpha, because those fuckers probably wouldn't hesitate and the heat of an Omega would hit them twice as bad.

"I couldn't, Cas-"

"You will, Dean." Castiel hissed through his teeth as he all but tore off the trench coat, leaving behind a business suit. The Omega couldn't want him this badly if he was in the right state of mind, it was considered non-consent, and Dean didn't do that.

"I don't care, one way or another I'd be at somebody's mercy, and it's better to have a level-headed Beta than an Alpha who's mainly running on stupidity and claiming rights." Castiel breathed heavily as he looked at Dean with those beautiful irises and blown pupils.

Shit, he's gotta point.

Dean crept slowly towards the Omega.

"Do I have your full consent before doing this? Like I know you'll more than likely regret this later, Cas, but I want to make sure that this is what you want, because I'm not going to take advantage of an innocent person." Dean stated clearly despite his melting resolve.

"You have my consent. Now hurry up." Castiel all but growled and Dean obliged.

"Not here. In my room." He grunted as he helped the Omega walk from the garage, to the upstairs connected to his house. The cool air from the air conditioning felt as if it was a major relief against Castiel as the two finally walked inside.

"You're ah! A good person, Dean." Castiel said through his panting, the heat being almost completely unbearable.

"I'm literally taking you to my room to fuck you, that's not a good person, Cas." Dean said as they finally reached the door to the bedroom. There was much hurry when Castiel felt his back pressed against the bed, Dean pinning him down and finally kissing him senseless.

"Says the person who kept asking for my consent. Good person, Dean." Castiel lightly argued as Dean took off his clothes, letting Castiel's hot skin meet the coolness of the bedsheets.

Dean felt a surge of warmth in his heart with the cute, flustered Omega praising him.

"Do you want to smell me?" He asked as he offered the scent gland in his wrist to Castiel. It was what mates usually did, but Dean felt obliged to treat the Omega like royalty before he fucked him into oblivion, at least he could give the Omega his comfort.

Castiel didn't hesitate as he took a breath, almost whimpering as the scent of butterscotch, green apples, and the metallic smell of Castiel's car that Dean worked on earlier. Immediately his eyes widened with recognition and awe at the unique scent of what felt like home.

"You." He all but said.

"Me?" He asked. It couldn't be, it was an old wives tale. Castiel lifted his head, baring his throat for Dean to smell, the Beta hastily obliged. A homing scent washed over him, leaving him in absolute surprise.

"Yeah," Castiel said, looking at what the irony of fate bringing them together. "You."

With renewed energy, Dean shredded off all of the remaining of his own clothes, then turned his full attention back to his supposed mate. Castiel could only whimper as he felt more slick trickle out of him and the feel of Dean's precum drip onto his stomach. His Beta was practically worshiping him as he peppered kisses along Castiel's jawline, stubble rubbing against stubble, hands caressing his hips and pinching his nipple. It was almost too much.

"Dean-" He groaned as his heat felt like an irresistible fire.

"What is it, Baby?" Dean's husky voice asked.

"The heat." Castiel reminded him that there wasn't much time, and Castiel needed to be bitten right now.

Dean really wanted this to last longer, he really did, but the two of them were suffering, right now.

"Alright, I'll take care of you, Baby." He kissed Castiel's neck before he stood up, turning towards his night stand and opening the drawer.

"Um, do you care what kind of lube we use? I got um apple pie or butterscotch?"

"Dean!" Castiel whimpered.

"Alright, alright, butterscotch it is." Dean hastily returned with the bottle, popping the lid open.

"We don't ah, need that, Dean." Castiel said. Dean shrugged.

"I want to prepare you, anyway." He admitted, causing a warmth flutter inside Castiel's heart.

"Alright." Castiel panted. He laid on his back as Dean poured a generous amount onto his fingers. It was slick, yes, but Castiel hated to admit that he never been stretched before. He forced himself to relax as two probing fingers entered him, wincing at the stretching intrusion. Dean stopped and stated.

"What?" Castiel asked. Dean kissed him thoroughly.

"So I'm your first?" He growled possessively between the kiss.

"Ah! Dean! Why, ah, does it matter?" Really, did it matter that he was a too busy workaholic who literally had no time for such things? He was still Castiel, no matter what he did or didn't do.

"Because I wanted to take this slow. I want you to enjoy it instead being pushed by damned hormones to rely on some Beta mechanic who wants to fuck you."

The words hit Castiel, letting his heart melt at Dean's sincerity.

"My Beta mechanic." He argued, liking the way Dean's eyes had darkened at that simple statement.

"Yeah. You're mine, too." Dean kissed him. Castiel whimpered.

"We're taking this slower, next time, though." He growled as he continued to softly caress Castiel's inside with two fingers, enjoying the way his Omega pushed back against them, ready for the last one.

"I promise I can't complain, Dean." Castiel promised huskily. He was rewarded with the third and final finger, softly stretching him inside.

After a minute, Castiel whimpered with need for Dean to go ahead and enter him.

The stretching wasn't anything compared to Dean's fingers, but it didn't really hurt. Castiel sighed with the odd yet satisfying feel of being full by his mate. His heart fluttered through his hazed thoughts. Thirty-three years, and he had finally reached the point where his mate was there with him.

He'd honestly would have felt giddy if he wasn't so needy right now.

"Dean," He rasped. "Move."

Dean complied, thrusting slowly, looking at Castiel's expression to see if there were any signs of discomfort. At each slow thrust, Castiel felt himself harden even more, if it was possible, as he seen his mate take gentle care with him. He knew Dean was trying not to plow into him, yet that thought made him even more appreciative that he was with a caring Beta who wouldn't hurt him like he heard of Alphas were capable of doing.

When Castiel felt that it was safe enough to thrust back, Dean's member had brushed against inside him and that made him feel like he saw stars.

"You can move faster, Dean." Castiel grunted as he felt desperate to feel more of it.

"Alright, Baby. I got you." Dean said as he gripped the bedsheets beside Castiel, wanting to go slow if the burning need wasn't so damned consuming.

"I'm not, ah, a delicate flower, Dean. I want you to move, ah, fast." Castiel complained. Dean couldn't help the grin as he then laced his fingers with Castiel's.

"You're so bossy. I like that." He admitted as he complied with his lover's demand, making sure he had hit that special spot inside Castiel. He watched in awe and burning lust as his Omega whimpered and started to tighten around him, meeting Dean's thrust sloppily and if that wasn't the hottest thing Dean had ever seen, he didn't know what was.

"I'm, ah! Close!" Castiel admitted. He felt Dean reach and grabbed his member, red and leaking with precum, gripping it hard and moving it into sync with his now erratic thrusts.

"I want you to cum first, Cas."

"D-Dean!" He whimpered.

"Come on," Dean leaned down and breathed huskily in Castiel's ear. "Cum for me, Castiel." At his full name being used like that, Castiel felt the spring within him snap and saw white as he shed his release. Taking this as an opportunity to distract him from the incoming pain, Dean lowered down his Omega's neck and bit down harshly, drawing blood as he then too came within his lover.

He would had felt pity, but his mate's scream was mostly from the over-building pleasure, not much from the bite.

It was all over. Castiel was panting, feeling a slight sting on his neck as Dean licked the bite, smoothing it over.

"Dean." Castiel mumbled. Dean raised his head and kissed Castiel's kiss-bitten lips.

"Hush, now. You can stay here as long as you want, alright? Get some sleep, Babe, and we'll talk it over in the morning." Dean said as he felt the aftermath of the sex taking a toll. He knew Castiel would probably feel sleepy after his first time like this, and so he would never push his Omega to do any more stressing.

"Thank You, Dean. You're a good mate. 'M glad." He mumbled softly as he looked at Dean hazily through dark lashes.

"Yeah, I'm happy, too." Dean admitted. It was the truth. Not only had that been the best sex he had ever had, but he knew that his mate was there and everything was okay. His mate. That made him feel more giddy than it should, but he didn't care.

"Now get some sleep." He finished as he pulled gently out of Castiel, and pulled the tossed blanket over both of them as he snuggled into Castiel's slight smaller frame.

…...

"Dean! I'm hom- WHAT THE HELL WELL OKAY BYE!" Sam closed the door in a rush, receiving the most icy glare from his older brother and a confused look from the younger man next to him.

Come to think about it...that car was in Dean's garage for the last five days.

Sam couldn't help but grin as he pushed the mental scarring images out of his mind. He'll never let his brother live this down.
