Chapter Text
"So, Sammy and his girlfriend are-" Dean cut himself off, taking in the sight before him.
Rae was ass up with her face buried in the pillows. She had one hand reached around her, fingers teasing her hole by pulling her lips apart and barely entering herself. Her other hand was under her between her legs. Dean lost himself watching her rub her cl*t, whimpering little sounds that oddly resembled his name. This continued for several minutes, before Dean noticed that his sister wasn't aware she had an audience.
Rae jumped upon hearing a deep chuckle, followed by Dean's gravel like voice. "I thought you wanted my help, omega. Or are you gonna make a mess of yourself, before I even get my boots off?"
She spun to face him immediately crawling down the bed to where he still stood. "gone so long, Alpha. It hurts, but you can make it feel better." Rae began scenting her twin, and running her hands under his many shirts. She giggled knowing, the smell of her juices wouldn't soon fade from his skin. "Please, De. Make me feel all better?"
"How do i do that?" Dean teased wanting to hear her beg for him.
Seeing through his ruse, Rae pulled open Deans belt, and reached into his pants to grab his co*ck. "I need you to f*ck me into the mattress. Alpha, please gimme you knot. need you stretch me out. Haven't felt you in such a long time. I'll be a good girl, I promise."
Dean grunted as she began to stroke his engorged member. He had forgotten how her hands grip him perfectly. "Lay down, Omega." he growled out.
As Rae did as she was told, however hesitant to release her grip, Dean began shedding his many layers, nearly falling over trying to remove his socks. Once he was as naked as his sister, Dean sprang forward and wrapped his omega in his arms.
"So tell me, what were you thinking about just now? What was making you rub yourself so hard, you didn't notice me come in?" Dean breathed against Rae's neck. He began kissing her anywhere he could reach, make her squirm under his ministrations.
"You- you were behind me. Holding me in place and treating my puss* as your own little f*ck hole. You told me to hold on for the ride. God, De. please just knot me already!"
"Now where would be the fun in that. We've waited so long, Whats a few more hours? I was thinking we could order some pi- OOF" Dean grunted as he was shoved on his back.
Rae climbed over top of him, immediately impaling herself on him. Dean grasped her hips holding her in place. He marveled at how after all this time she felt just as amazing as the first time. Her sweet puss* wrapped around him so perfectly, like it was made for him to fill. Rae knew from the way her brother was shaking, neither of them would last very long. As soon as Dean loosened his grip, Rae began to move, sliding up and down his co*ck, sensually rolling her hips over him. She alternated between a slow rise and fall and grinding her hips into his.
As this continued, Dean sat up cradling his sister to his chest. He locked lips with her in a hot needy kiss. How had he let her slip away? How could he have been so stupid, to deny his mate all these years? Dean pulled away from the kiss, gasping for air. Rae in turn, began kissing his jaw, leaving a trail down his neck to just over his mating glands.
Dean's knot was beginning to catch on his twin's rim. "Oh, sweet heart. I'm so close, Rae. Wanna feel you squeezing my co*ck." Dean babbled as his sister continued to lick and suck over his mating glands. "Fu- f*ck! Cum all over me, Omega!"
Dean's words shot through Rae, and she clamped down on him, both with her twitching puss* and her teeth. She tasted her brother's blood as it rushed into her mouth. Feeling the bond solidify between them, Dean's knot exploded, filling his sister with spurt after spurt of his seed. "MyalphaMymateAllmine" She chanted, repeating the mantra that was going through her head.
They slowly came down from their respective highs, they became more aware of what just happened. Rae stiffened and tried to pull away, whimpering in pain from the sharp tug of where they were tied together. She began to panic, now that the fog had temporarily cleared. She bit him. Dean didn't bite her. That is unheard of, an omega laying claim before an alpha. She knew her brother was going to be furious. Rae began to shake with fear not knowing what was going to happen. If Dean didn't want this, Rae would die. An alpha may be able to survive without their mate, but once the bond was in place, an omega was dependent on their alpha. going long periods of time without their alpha, would make an omega sick. Experiencing a heat alone, would kill an omega with the fever alone.
Not quite grasping his omega's fear. Dean floated in the euphoric feeling, knowing he wouldn't be kicked out as soon as this heat was over. Rae wanted him. She needed him as much as he needed her. She wasn't taking the chance of him leaving her this time. When the fog of mating hormones cleared, Dean noticed Rae's panicked state. Her scent was sour and and bitter.Did she regret this? Was it really just her heat that led them here?
"De, I'm sorry- shouldn't - but you were right here- and i just - i couldn't stop myself- God what have i done?" Rae babbled, unable to hide anywhere else she buried her face in Dean's chest.
"No, Sweetheart. Talk to me please. I smell hear your brain cooking from here. What wrong, sis? Did I-"
"I bit you." She whispered.
Had she not been on top of him Dean wouldn't have heard her. His heart sank. She didn't want him. And now she was stuck with him.
"Please forgive me. I was so weak. I should have left when i got you home." Dean said into her hair.
"What? No?! That's just the new mark talking. I should never have bit you. It's not my place. I know you didn't want to be my mate. Your heart has always been bigger than your brain, and i used that. I knew you wouldn't leave once you saw how much I needed you. But i swear, Dean, i never meant to trap you like this." Rae began babbling again, Pleading with her eyes for dean to understand. "you don't have to stay with me. I can-"
Dean shut her up with his lips. She had it all wrong, he thought she didn't want him. Understanding now that they're both idiots, Dean began to laugh. His soft chuckles turned into full belly shaking laughs, which managed to illicit soft moans from the still knotted pair. when he calmed himself, all Dean managed to get out was, "God, you're perfect."
Rae stared at him. Her confusion was quite clear. "But I-"
"You've been my mate since before Sammy was even born. Although its never been obvious how blind both of us have been, until now." Dean smiled, "I'm so in love with you."
"You aren't mad that I bit you?" Rae asked meekly.
"Oh, God no! In fact you helped me out a great deal, cause now i don't have to worry about accidentally mating you, before i knew if you wanted my bite." Dean reassured her.
"I would have taken your bite when we were fifteen." was her response, before she dove back in for another kiss.
Eventually the new couple settled, trying to rest before the next wave of Rae's heat hit. This was going to be a good week.
~~~
When her heat had finally passed, Rae woke up in a tangle of limbs. Dean was still quietly snoring behind her, snuffling occasionally as if her hair was in his face. Rae gently rolled over in his arms and took in the sight before her. Dean looked so peaceful, like all the weight had been lifted from his shoulders. Rae smiled affectionately at her mark, gently tracing the scabbed skin with her finger tips. The sensation caused Dean to stir, groaning softly as he came to.
"Morning, sleepy head." Rae crooned at him. He grunted out a rough "M'ning" clearly not quite awake.
A bang from the kitchen had them both shooting up in bed, and quickly pulling on some clothes. At some point during her heat Dean had gotten his duffel bag out of the Impala. Both dressed, Dean led the way into the kitchen, one arm wrapped protectively around his twin. The new couple was greeted by the sight of Sam and Jess putting away groceries.
"Oh look who's finally awake. Welcome back to the real world, love birds." Jess teased.
Sam was approaching slowly, unsure as to whether it was a safe decision. "Hello, Dean. I'm not going to hurt her. I would just like a hug."
"Uh, yeah okay, Sammy. Don't you think you should be asking Rae?" Dean shuffled to the side awkwardly, making room for his overgrown brother to hug their sister.
"Six days ago, you tried to attack me when I walked in the apartment with food, for you guys. I thought I'd be better off warning you of my approach." Sam explained.
Rae piped up "Six days ago, Sammy? We just went to the store, the morning my heat his."
"This is the first intelligible conversation We had gotten out of you two, in Fourteen days." Jess remarked. "I think being on suppressants so long made your heat almost twice it's normal length. Not to mention, Dean went into rut three days ago."
"It's been two weeks? I thought it had only been four or five days!" Dean exclaimed.
"We were starting to get worried, honestly." Said Sam.
"Thank you for keeping an eye on us. That could have been very dangerous." Rae said.
"I'd say anytime, but I'm certain that i never wanna hear 'Please put a pup in me!' come out of my sister's mouth, ever again." Sam sounded ready to gag.
"Or 'you feel so good on my knot' coming from anyone but Sam." Jess added.
Everyone laughed and moved into the living room. Sam and Jess took, the couch, leaving Rae to settle into Dean's lap on the chair, curling around him like she was trying to merge into his skin. The conversation morphed into catching up, realizing that even though Dean had been back for two weeks, intellectual thoughts really hadn't been shared during that time.
"So what's the plan now?" Jess asked. "Is dean going to be moving in with us? Or are you going to move back home, Rae?"
"Well I suppose once dad got over the shock of things, he'd love having a woman's touch around the house again." Rae thought aloud.
Dean made a small choked sound, like he just realized he forgot something very important.
"Dean? What's wrong?" Rae asked.
"Well, I'm sure Dad would love t see you again, we can't move in with him."
"Dean,what's going on? Where's Dad?" Sam asked, concerned over the man who never actually was a father to him.
"There was an accident-"
"Oh, God! When Dean? Why didn't you call when he passed-" Rae interjected.
"Whoa, slow down. Dad's not dead." Dean calmed his omega, petting back her curls. "Like I was saying. There was an accident about six months ago. Dad was drunk, He said he was on his way home from the bar, but it was seven in the morning. Dad t-boned another car. The girl was alive when the EMTs arrived, but she died before they got to the hospital. Poor kid didn't even have her license for a month yet." Dean paused calming himself down this time.
After a few deep breaths Dean looked around the room, "Dad's in prison. He got 10-15. I haven't seen him since the night he was arrested."
