A/N: I got this idea awhile back and I decided to flesh it out to see how it goes. This idea does play on the transgender issues but more so with omegaverse and Alpha to Omega transitioning.

"You don't have to be here for this…" Dean said.

He bounced his fingers on his knees as he and Sam sat in the waiting room of the small clinic with him.

"Course I do," Sam replied. He reached over and squeezed Dean's shoulder reassuringly. "I think what you're doing is brave Dean."

Dean rolled his eyes and didn't say anything. He ignored the looks the other people in the clinic were sending their way. There were mainly omega and alpha couples with a few betas and single omegas.

Dean knew he was nervous, and a little uncomfortable. His scent was no doubt making the omegas shrink closer to their alphas, and Dean resisted the urge to do the same. He was starting to regret allowing Sam talk him into this and almost stood to leave.

"Dean Smith?" The nurse said.

She was a small petite blond and she eyed Sam and Dean like two slabs of meat while simultaneously blushing like a schoolgirl as they walked over. Sam had his hand on the small of Dean's back, his own taller frame blocking the action from everyone's view as the nurse led them down a small hall.

"Just have a seat, Dr. Roberts will be here shortly," she told them.

Dean sat down in the plastic chair and rubbed his palms on his knees. "Maybe we should just leave…" he said.

"Just relax Dean, we're just here to find out some information okay?" Sam replied. "Look at me."

Dean huffed out a breath but looked at his brother and Sam leaned in giving him a chaste kiss. He leaned into it, despite the possibility of them getting caught and felt a bit better once they parted.

"Good afternoon gentleman," an older man said as he walked into the exam room. A beta. That made things a little easier.

"Afternoon," Sam nodded in greeting.

The elder man sat down in the cheap rolling chair and picked up the medical information Dean had filled out. He looked it over, nodded in satisfaction, and fixed the two with a neutral look.

"What seems to be the problem?" He asked.

Dean's tongue felt like it was stuck to the room of his mouth. He couldn't do this.

"I'd like some information on Alpha to Omega transitioning," Sam said before Dean could bolt. He had the decency to look embarrassed and even his scent changed to a salty musk.

Dean chanced a glance at the doctor.

"Is that so?" The doctor asked. "Are you considering the procedure?"

Sam nodded a little stiffly keeping to the embarrassed but also nervous act.

"My older brother filled out the medical information for me because I...I was just too nervous," Sam ducked his head letting his hair curtain his face.

Dean swallowed. "My brother's been feeling this way his whole life," he added. "Our dad...He, uh, wasn't too supportive you know."

Dr. Roberts nodded. "Well, I don't know how much you know of the procedure," he said. He went to one of the drawers and pulled out a few different pamphlets. "It's not something to be taken lightly. Now, you don't seem the type to joke about something like this so I'll write you a prescription for omega pheromones. It won't be as potent as being an honest omega but you will feel what they feel. If you are serious about this, give me a call and we can see about starting the next steps." He gave Sam the pamphlet and the prescription note.

Dean sagged against Sam once they were in the safety of the Impala and closed his eyes.

"Bitch…"

He felt, rather than saw, Sam's small chuckle and felt his lips against his forehead.

"Jerk."

"You didn't have to do that," Dean sighed.

"You were gonna bolt," Sam replied. "Couldn't let you do that."

Dean snorted. "Why not?" He opened his eyes and watched a couple people walk out of the clinic.

"Dean…" Sam said, using his 'you deserve so much and I want to give you everything' voice.

Dean shook his head and sat up to put the key into the ignition. Sam tucked the pamphlets into their duffels on the back seat as Dean pulled out of the clinic parking lot and drove to the nearest pharmacy.

"You want me to get it?" Sam asked as they parked.

"No...Yes...Fuck I don't know," Dean answered. He ran a hand through his hair and sighed. "Yeah, yes, grab some beer too would you?"

Sam nodded and Dean waited as he went into the small grocery store. He drummed his fingers on the steering wheel and watched people walk in and out.

He was getting a bit impatient when Sam walked out with the plastic bag. He set it on the seat between them as he got in.

"Swear that pharmacist gave me the fifth degree," Sam muttered. "Thought I was gonna use it for sex or something."

"Well….it sometimes is used for just sex, or for Alphas to experience what their mate goes through sometimes," Dean said with a shrug. "Sort of a literal 'Take a walk in my shoes'".

Sam blinked. "How do you know that?"

"...You're not the only one who does research," Dean muttered. "Where to next?"

Sam flipped through the possible leads he saved on his phone. "Looks like there's something over in Washington. Nest of vampires."

"Been looking forward to chopping something's head off, let's check it out," Dean said as he pulled a U and started driving in the right direction.

Sam chuckled and put his phone back into to his pocket and stretched out as best as he could. He saw Dean shifting glances between the bag between them and the road every so often and licked his lips.

"Should pull over for the night," Sam said after the sun had set and the roads were dark save for the impala's headlights and a few passing cars.

"We're like halfway there," Dean replied.

"I'm hungry, and tired," Sam said. "There was a sign that mentioned a Shari's and a motel. Please?"

"Only because they've got decent pie," Dean answered.

Twenty minutes later they pulled into the restaurant's parking lot and got out. The hostess led them to a booth and they sat down across from each other.

"You wanna try it out when we get to the motel?" Sam asked once they put in their order. "Or we could wait." He could sense Dean's hesitation and didn't want to press him if he was still nervous.

Dean picked up his beer. "After the hunt...We'll go to one of Bobby's cabins or something."

Sam nodded. "Alright, sounds good."

He thanked the waitress when she returned with their orders and picked up his fork, digging into his salad.


"Think it'll feel weird?" Dean asked.

"Hmm?" Sam turned his head at the sound of Dean's voice half asleep and half listening to his brother.

"Those pills," Dean answered.

Sam wrinkled his nose as Dean moved around in the smallish bed. Two grown Alphas were not meant to sleep together in a small twin. He opened his eyes and they adjusted to the dark. Dean's weight was solid on top of him where he was straddling his hips.

Bare skinned, and the moonlight hitting his eyes just right to give them a soft glow. Sam reached up and ran his fingers down Dean's chest.

"Weird how?" Sam asked. "It's just supposed to make you feel like an omega right?"

"Feel...act...smell," Dean trailed off and it took Sam a moment to realize Dean was a bit giddy at the prospect. And aroused. He leaned down and pressed flush against Sam and kissed him. He curled his fingers into Sam's hair and tugged.

Sam groaned low in this throat and bucked up slightly. "Fuck, should take you out when you take 'em. Then I can properly show everyone you belong to me."

Dean chuckled and grazed his teeth over Sam's scent gland. "Yeah? Gonna mark me up nice and good baby boy? Make me your bitch?"

Sam growled and grabbed Dean's hips. He tugged at Dean's boxers and whined when the older male pulled away to take them off, Sam's followed suit and the clothing landed on the floor. He flipped them and used his body to press Dean into the mattress and spread his legs.

"We're gonna do whatever you want after the hunt," Sam promised as he got the lube. He kissed the inside of Dean's thighs and coated his fingers.

Dean arched a little as Sam thrust in two fingers working to stretch him. "Anything?" He breathed.

"Anything, carnival season you know. Could go to the county fair in Oregon for once," Sam said as he added a third. "Win you a teddy bear. How does that sound?"

"Yeah?" Dean moaned. "Win you a giant slinky. Always wanted to get you one of those. Loved those things when you were a kid."

Sam chuckled and leaned up to kiss him. He removed his fingers and slicked up his member and lined up with Dean's hole. Dean had an arm hooked around Sam's neck keeping him close and moaned as Sam started to push in.

A steady stream of filth mixed with love was whispered into Dean's ear while Sam set a slow pace. He'd pull out til the head of his cock was just inside and thrust back in, rocking them together.

"Feel so good Dean. Always so tight, could stay inside you all day," Sam panted into his neck. He mouthed at Dean's scent gland and bit down gently as he thrust harder and faster.

Dean panted beneath him and started to stroke himself fast. "Oh fuck," he moaned. The hand still curled in Sam's hair yanked his head back and Dean bit down hard on his collarbone as he climaxed. He tasted salt, and the coppery tang of blood.

Sam held himself inside Dean as he came. He looked forward to the large hand sized prints that'd be on Dean's hips in the morning. He pulled out slowly once Dean released him and watched his cum slide out of Dean's stretched and red hole. He teased it gentle with his fingers.

"Stop," Dean huffed out and tried to slap his hand away. He rolled over onto his stomach. "S'gross."

"Not gross," Sam leaned down to kiss Dean's shoulder and got up to get a towel bathroom. He cleaned Dean up and got him into the other bed and pulled the blanket over them once they settled.

"Did you mean it?" Dean asked. "What you said?"

"Every word," Sam promised.
