A stream of high pitched babble spilled from the principle's lips while tried to pry the boiler room door open with a piece of rebar.

Millie caught her breath and pointed a shaky finger down at the pile of flesh, hair and teeth lying in the middle of the room, "What is this?"

Sweaty, dirty and naked Castiel didn't feel in the mood to stop and answer questions. It was easy to ignore her; he was used to high pitched babble from his daughter.

The woman lost it again, "We are going to die aren't we? Die, die, die, d…"

Castiel dropped the rebar and grabbed Millie by the shoulders, giving her a good shake, "Calm down, you aren't helping."

Exhausted and confused, the principle went slack but Cas caught Millie before she hit the floor. He led her to a stack of crates and had Millie sit. He crouched down in front of the dazed woman and laid it on the line. "Most likely your brother is dead. As I said before, that thing is a shape shifter and the pile of waste is the Wade suit it had been wearing. Are we going to die? Not if I can help it. I'm going to kill that thing."

The teacher softened when he looked into Millie's haunted eyes. Cas cupped her cheek gently, "Do you understand me?"

Millie sobbed, "How will you kill it?"

"I believe silver to the heart."

"My brother could still be alive."

False hope was better than no hope at all. He played along, "Perhaps. Can you manage to stay calm?"

She nodded, "I understand, I'll be calm." The principle grabbed the teacher's hand, "You really are a good and decent man. I was so wrong to judge you and your family."

"Yes, you were wrong."

"I'm sorry."

"You can prove how sorry you are once we get out of here and I save my family."

….

Sensing something was wrong, Dean pulled back, searching his husband's face for a clue to his feelings, "Babe, are you still upset about today?"

Gregori took full advantage of his facsimile of Castiel's beautiful blue eyes, he cast them toward the floor then locked eyes with the Omega, "Yes, today was very stressful."

The smell of sex escaped the confines of the flannel robe Dean was wearing triggering stolen memories in the shifters mind of the Alpha and Omegas smoking hot times between the sheets. He became aroused.

Gregori slid the robe from Dean's body then palmed his firm, young ass, "I believe you had some stress relief in mind."

The young Hunter gave the wolf in sheep's clothing a salacious smile, "Major stress relief. I'm horny as fuck and Grace is asleep sooo…"

Dean tried to kiss Castiel but Gregori turned his head away. The shifter spun him face forward and slapped his butt cheeks, "Bedroom…now."

…

The shifter smiled down at his trusting captive, thoroughly enjoying his little game, "Something like that." He stripped down to his Castiel's birthday suit and then slipped the Alpha's boxers over Dean's head.

Dean had just spent the afternoon enrobed in Cas' hamper clothes so the new twist just added to his excitement. This action helped the shifter in several ways, the Omega was surrounded by his mates scent and Gregori wouldn't have to kiss Dean.

Shape shifters had incredible abilities to mimic and deceive but two things they couldn't replicate was the scent and taste of the person whose form they took. Normally scent wasn't an issue but when posing as someone's mate and in an intimate situation, it was a tip off.

…

After removing decades of junk away from the walls of the basement room, he found what he was looking for, a coal chute. He pulled the heavy iron door open and peered up the short shaft; there was another door with moonlight filtering in around the frame.

Millie, meanwhile, had been searching for something for Castiel to wear. She opened a storage trunk and found ancient band uniforms from the 1950's. Millie pawed through them until she found a decent fit for the teacher, the uniform; along with a pair of old galoshes would go a long way in keeping Castiel warm.

Cas put on the grey, wool pants and matching jacket with red accents complete with epaulettes, gold buttons and a lot of pizzazz. She draped the matching cape around his shoulders then stepped back to admire, "You look handsome."

"I'm going to climb up. Do you think the janitor is still here?"

Millie checked her watch, "No," Millie handed him her keycard, this will get you inside. Go to my office and get my purse, you can have my car keys. The lost and found always has plenty of orphan clothing and shoes." She took off her pearl button cardigan, "Wrap this around your waist so your bits don't fall off."

She grabbed Castiel's forearm tightly, "Promise you'll let me out before you leave."

"I promise."

…

Dean pulled the boxers off his head and shoved his fake husband on his back, the Omega swung a strong leg over the shifters hips and pinned him, "It's my birthday next week aaand…" he waggled his eyebrows.

Gregori had no idea what he was trying to get at.

"What are you trying to say?"

Quick as lightening Dean had the shifters wrists pinned over his head, "I want in, I wanna do it to you. A guy only turns seventeen once. Tonight I'd like a preview…do a little hotdoggin' between those sweet booty cheeks."

"What?!"

Dean used his powerful thighs to hold his lover's hips in a death grip, "Come on babe, give your wifey a little sugar."

The shifters first instinct was to snap Dean's slender neck and be done with it, after all, a monster has his pride, but there was something about Dean that made Gregori want to please him. Even though the teen reeked of Hunter and seemed like the most dangerous sex partner in the world, the shifter was horny and honestly, the Omega was the most delicious creature he'd ever laid eyes on.

He pulled a memory of he had of Castiel on his hands and knees, ass in the air and Dean Winchester working his impressive, young dick back and forth across the teacher's asshole while Cas cried out in Latin. In Castiels stolen memory the teacher had also received a gold star blowjob right before that. Apparently Dean was a beast in the sack.

It gave Gregori a tingle in all the right places, he found the memory weird but exciting and there was something about Dean's bottle green eyes that left him feeling weak and willing.

…

Castiel kept his word, he released the principle before leaving to save his family. He put the pedal to the metal despite the icy roads, throwing all caution to the wind. When the Alpha reached the end of the drive leading up to the farm house, he parked so as not to alert anyone. The element of surprise was all he had, that and the sterling silver letter opener he swiped from Millie's desk with "20 years of service" engraved on the blade. It was the least the principle owed him considering all she put his family through.

Cas found the front door unlocked. He kicked off the galoshes leaving him barefoot then did a quick sweep of the ground floor before sneaking up the stairs. First he checked on Grace and was relieved to find his daughter asleep, then Cas crept toward their bedroom and the closer he got to the room the louder the sounds became.

Wanton moans were heard along with the familiar sound of the headboard pounding against the wall in a rhythmic fashion. "That's my voice."

When Castiel heard Dean let out a loud whoop followed by, "Yeah, who's my bitch?" and the wolf in Cas skin answering, "you are. Harder!" The Alpha saw red.

"Be calm, be calm… remember the element of surprise…quiet."

The Alpha almost lost his cool when he opened the door to their sacred marriage room. Dean had the imposter on his hands and knees; the Omega was just shooting his load over the imposter's back.

Castiel shoved his startled mate to the floor and plunged the letter opener with all his strength through the shifter's back. Using all his weight to drive the blade in, the silver opener pierced Gregori's heart.

The monster had been in a sex fueled haze and off his guard which gave the furious Alpha an advantage. As blood flowed from his damaged heart and the organ started shutting down, Gregori could only manage a weak punch to Castiel's face, giving him a matching shiner to the one Dean had given Cas by accident.

Dean aimed the pistol with the silver bullets first at Castiel and then the now lifeless shifter.

Castiel climbed off the body and put his hands in the air, "Dean, it's me. That thing was a shape shifter."

Dean waved the pistol, "turn around and don't move or so help me I'll blow a hole through you without blinking." He approached Castiel from behind, "drop those stupid pants."

"Dean…"

"I said drop 'em."

Castiel pushed the uniform pants down around his knees, leaving his ass exposed.

"Stay still." Dean unceremoniously stuck a finger up his husband's ass, causing the Alpha to yelp.

Dean pulled his finger out then sniffed it. It was gross and messy but a sure way of finding out if this was his Castiel or not. There was no time for sweat analysis or saliva. The Hunter was mortified; he'd failed to discern his mate from an imposter.

Castiel heard Dean whimper, "Cas?"

…

Sioux Falls, South Dakota

Viola Lavin did a slow stroll around Bobby Singer's amazing library filled with rare books, oddities and amazing, supernaturally charged times that Bobby had on lock down.

She ran a long, red nail down the spine of thick book, "Bobby, you have such an impressive collection."

Bobby dropped his ball cap on his desk and took a seat. The Hunter was exhausted after his latest hunt with the aid of Viola. "It's not a collection as much as tools."

Adeline, Bobby's child with his Omega wife Nicky, dashed over to her daddy and climbed on the tried man's lap. "I missed you, Daddy!" She peppered his face with kisses and all of Bobby's aches and pains melted away. The little girl handed her dad a drawing, "I made this for you."

Bobby chuckled when he say the crude crayon picture, "Awww, it's me chopping the head off a vampire, thanks, Ladybug." He gestured toward Viola, "Adeline, this is my friend Viola."

Addie hopped off her daddy's lap and went to the stranger, extending her little hand, "Please to meet you. Are you the psychic daddy told us about?"

Viola crouched in order to get on the six year olds level and shake her hand, "I'm happy to make your acquaintance. Yes, I'm the psychic; my gift comes through in visions."

Addie gave the lady a big smile, "Cool!" She skipped off to see what her mommy was up too.

Viola noticed a framed photo Bobby had taken at Castiel and Dean's wedding. In it, Sam and Dean were dressed to the nines, arms around each other and all smiles. She picked the photo up to get a closer look, "Bobby, tell me about these boys."

"Sam and Dean Winchester, John and Mary Winchesters boys, I took that photo at Dean and Cas' wedding reception…I guess its Dean Winchester Novak now. I feel bad I haven't gone to see them again. The kids have been through a lot in their short lives…they are good kids."

"I had a vision of Sam and Dean just a few days back."

"Don't keep me in suspense, are the boys ok?"

"In the vision, I saw an orb sending out a beacon into the ether in order to draw dark entities to it. For what reason, I have no clue, perhaps to feed off the energy of the creatures drawn to it. The orb is located somewhere near the young one. It lies hidden, waiting to be found. Bobby, this orb needs containment or I fear for these children."
