A/N- Look up "Swearin' to God" on YouTube. I had the song suck in my head with Castiel singing so I had to get it out. My mind went off track again. Enjoy.

With her head tilted back and eyes fixed on the monstrosity, Grace was frozen in place. No one else saw it's the teeth and the ugliness emerge from the beauty, only her. She said under her breath, "masure". She meant to say "monster" but the pronunciation was still beyond her language skills.

"There you are." The sitter lifted the tiny runaway tot into her arms, "Grace, it's dangerous to runaway."

Now safe in the arms of an adult, Grace pointed an accusatory finger at the stranger and called him a "masure".

Monsters and in this case, vampires, knew most children could sense the supernatural, much like animals. This was a gift that most humans outgrew or outright shunned because of disbelief or the possibility of accusations they were crazy. Then there were kids like Grace, a natural sensitive, they were the most dangerous of all to things that went bump in the night, since some became Hunters or mediums.

If it were up to Lucian, he'd have drained the tot dry on the spot for a snack and make the world a safer place for creatures like him and his brother. But the vampire let it slide, at least for the time being.

….

It was naptime and after a diaper change and a snack, the exhausted children had no problem falling asleep. There were a few extra travel cribs set up in Alex's bedroom for the Lafitte twins, little Adam and Isabelle.

Grace fought sleep as long as she was able. Alex patted his best friend on the back to comfort her. After awhile sleep won out and Grace fell into fitful dreams. She would have to tell her parents about the monster later.

….

The twins decided to only pick out one victim this evening. They were new in town and after barely escaping with their heads from Romanian Hunters, the brothers were cautious. Lucian and Dmitri had learned their lesson. If you're too greedy you attract unwanted attention.

Lucian wanted Javier very badly, the brothers preferred Omegas over women when they had more than feasting on mind. Sex played a major role for them and the bonus of a target with both sets of genitals along with the three available holes made Omegas all the more attractive, although Lucian and Dmitri would never turn down an exceptionally attractive young female or Beta. Sometimes their tastes ran toward Alphas just for the thrill of the hunt and the chance to break a dominant Alpha's spirit was exciting.

Dimitri nixed the idea of taking Javier. Yes, he was small, tender, young and pretty but his mate was large and strong and though the brothers could have dealt with Benny easily enough, Dimitri said it would be better to take one of the unattached morsels. There were certainly many to choose from.

Now they just needed for darkness to fall and all advantages it afforded.

"Excuse me."

The brothers stopped their quiet conspiring to turn and find Castiel and Dean, the teacher and delicious looking graduate, standing behind them.

Castiel did the introduction since Dean was already bored and wanted to get back to the action. "We wanted to personally welcome you to the neighborhood since you live right across the street from my father.

Dimitri smiled sweetly at Castiel though his eyes were on Dean, "Thank you. My brother and I appreciate all the kindness since we moved here. You can imagine how difficult it is to be in a new country and learn the customs and subtleties of the English language."

Castiel felt empathy for the young men. During college he tutored foreign students in English for extra money. "You speak very well, with time and practice the rest will come easily enough."

Lucian gave Castiel a lascivious smile, "Ai un fund frumos."

Castiel cocked his head and gave the pretty boy a quizzical look, "What does that mean?"

Dmitri had to stifle a laugh, "It means, you are so sweet," "It means, you have a nice ass."

Lucian continued his brazen comments, "O să-ți dau soția."

Castiel was enjoying this; languages fascinated him, "What does that mean?"

"We should have you both for dinner sometime." "I'm going to fuck your wife."

The teacher shook his head and smiled, "I'm lost. You have a fascinating language. Now I'm interested in learning Romanian. Tell me, what dialect do you have?"

Dean yawned loudly and stretched his arms, "I'm going back to the pool. Scotty challenged me to a chicken fight," he slipped his fingers into the waistband of Cas' trunks, "I need you to bottom."

"Excuse me?"

"You know, I need to sit on your shoulders…unless you want me find someone else to wrap my legs around."

Dimitri couldn't help himself; he grabbed Castiel's hand and kissed it, "We'll talk later."

The Alpha wasn't sure how to feel about the kiss but he chalked it up to their customs. The feel of the young man's cool lips brushing against his skin caused goose bumps despite the hot weather.

Dean, hormones at full blast and in a protective mate mindset, went and bumped chests with the interloper, I've got something for you to kiss."

When Dimitri didn't rise to the bait it made Dean all the angrier, "My ass…I mean you can kiss my ass."

"I'm sure it's a lovely ass, present it and I'll give it a kiss, I might even use tongue."

While Dean contemplated taking a swing at the smirking pretty boy, Castiel grabbed Dean around the waist and maneuvered his wife as far away from the twins as possible, "Dean, I think that is their custom."

"Being rude assholes?"

"No, the kissing of the hand, they aren't familiar with the way we do things here so I'm cutting him some slack."

"Fuck Count Dracula and is brother too."

"Why don't we play that game of chicken you were telling me about, what is it anyway?"

….

Sam volunteered to be the announcer, "On this side weighing in at…" Scotty shut him down with a look of death, "Scotty Novak riding Martin Bello. On this side weighing in at…" Dean flipped his brother off, "never mind, Dean Novak riding Benny Lafitte."

Sam didn't understand why people started laughing.

"These featherweights will go into battle as soon as I blow my whistle. May the best man win."

Castiel refused to be part of something so strange and potentially dangerous. He told Dean not to do it in fear his pregnant Omega would get hurt. That made Dean want to do it even more and the Alpha gave in when his dad assured him this was perfectly safe.

Dean made an overly dramatic gesture toward his opponent and did a little smack talk, "Your goin' down, blondie. The bigger they are the harder they fall."

Scotty did him one better, he raised his fists skyward, voice booming, "The strength of Tyr, my Viking ancestors' god of war, is coursing through my veins. Victory will be mine and when this is all over I'll be kind and spare your life but take you as my slave."

Dean wondered if this had been such a good idea.

Martin wanted to bail, he was already sorry he volunteered to be Scotty's horse. Scott Novak was tall and heavier than he thought but Martin was a big boy and besides Benny and Sal, there were no others who were willing or able to carry him.

"Go have some fun Martin" Mason says…thanks bunches."

Scotty grabbed a hank of Martin's long, thick, curly mane and yelled, "Forward."

Dean and Scotty clashed when they reached the center of the pool, bumping chests, locking fingers and exerting every bit of muscle to take the other down. The older Omega had height on his side but Dean was a natural scrapper and trained in fighting.

The grappled with each other for a long time but in the end both Omegas tumbled off the shoulders of their "horses" and continued wrestling in the water.

Someone yelled, "Loser makes out with the winner."

Dean was getting tired so he played dirty by yanked off the other Omega's swim trunks then held them in the air, "I win."

Scotty snatched them from Dean and used the trunks to hold the teen against his chest while he used his nimble legs and feet to shimmy off Dean's trunks. He tossed them poolside.

In a soft tone so only they could hear, Scotty whispered directly in Dean's ear, "Now who wins." He kissed him on the neck then swam for the ladder and exited the pool.

Most everyone went quiet as the nude Omega strutted past them, erection bouncing as he went. Winning was very exciting.

Spencer was on his feet in a flash, "We'll be back in a bit. Something came up that needs handling." Swim trunks tented, Spencer followed his wife inside.

Castiel handed Dean his trunks before he exited the pool. He didn't want the others to see his wife's tender bits.

"Dean, you're not doing that again, I mean it. Looked at you, your exhausted," He draped a towel across the worn out Omega's shoulders and took him inside.

….

Instead of tucking his wife in for a short nap, Castiel pushed him onto the mattress and pulled off a surprised, Dean's wet swim trunk. After watching the Omegas do battle, the Alpha had a boner the size of Texas.

Dean tried to pretend he was upset with the rough treatment, "Stop pushing me around, I'm not a goddamn whore."

Cas pushed his fingers inside his Omega's juicy snatch and grabbed the teen's raging hard on, "You lying little bitch, you want it so bad I can smell it." He pulled out his wet fingers and licked them clean. "I can taste it. If I didn't know any better I'd think you wanted to fuck around with Scotty." The Alpha's eyes were blown black with only a ring of cerulean to belie their true color.

That had crossed Dean's mind in fantasy only, it was line you didn't cross but it was sure fun thinking about it. He didn't realize Castiel had pick up those vibes from him. Dean was both embarrassed and titillated at this revelation. He took a leg and hung it over one of his husband's shoulders, "Why, does that turn you on?"

Dean was unceremoniously doubled in half and his mate's long cock slammed inside him. Cas fucked Dean like a champ, hard, unrelenting, all tenderness out the window. The knot inside him grew so large it felt as if he'd rip open but the walls of an Omega's vagina were built for this.

Castiel shot quickly, with the knot deflating almost as fast. Dean left a puddle between their bellies and all over the bed quilt.

They showered together then put on fresh clothes. Both wore cargo shorts and a tee, Dean's shirt was his favorite worn out Pink Floyd and Cas' a shade of olive. Their fucking invigorated Dean and he was more than ready to take on the rest of the evening.

….

The sun had set and the tiki torches were lit. The pool area went off limits because it was time for karaoke.

Benny had turned Castiel onto sake bombs and after two of them, Cas was lit. With little inhibition left, the Alpha decided he needed to take a shot at karaoke. With a little help from costume lovin' Scotty, Cas raided his dad's closet and found a glorious brown polyester bellbottom leisure suit and cream wide lapel silk shirt along with the grooviest belt ever. He topped the outfit with a kerchief around his neck. Cas was the hippest guy at the party.

Cas had a questionable voice but Scotty assured him he made up for it in good looks and smooth moves. The Omega shoved him up on the makeshift stage, "You've got this."

Dean let out a whistle and shouted, "Yeah, babe, show 'em what you got."

Javier, Shonda and Renee surrounded a microphone on a stand, ready to sing back up.

"Swearin' to God" by Frankie Valli came through the speakers and Cas revved up the crowd with a little hip shakin' to the groovy intro.

To say some of the ladies, Omegas and a few gay Alphas and Betas, found Castiel exciting was an understatement. After watching him all day in only swim trunks and a glowing tan, the consensus was many of them would love to hit that.

Pointing down at his wife, Cas was going to sing this directly to Dean and he wanted him to know it.

(ooooo) Swearin' to God
There's no one else on earth I'd rather be
Mmmmmm... Swearin' to God
You made me see so I believed in me
Oh you've been fillin' my cup
'Til I'm runnin' over with joy
From you heaven sent love
Just touch me again
I'm king of all men... and reigning from above….

He danced over to the backup trio.

Swearin' to God (Swearin' to God)
Your mistress of the world and all I am
(Don't tell the angels)
Swearin' to God (Swearin' to God)
Your where I won in paradise... began
No one gets me up there like you can
But girl you know I'm only human
And I'm swearin' to god (Swearin' to God)
So glad you've givin' me, you….

Drunk and high on the catcalls and whistles, Cas took off his sweaty kerchief and tossed into the crowd then peeled off the jacket. The sweaty cream silk shirt clung to his chest and torso, giving a peek of nipples and muscle.

(I was known for you, baby)
Girl ain't you glad we made it
(Made to give my heart and soul to you, baby)
I'm so very glad you gave it
(Hey baby were together)
Try livin' on forever as long
As long as we live….

Later Cas would see his performance on YouTube and cringe, but for tonight, he felt on top of the world, up there singing to Dean. It's amazing what a little liquid courage can do.

Bobby took a long draw on the straw stuck in his tequila sunrise, a drink he'd never touch except at a party because he was a beer man but when in Rome and all that. "This reminds me of that Elvis concert I went too back in the day."

Sam's eyes widened in surprise, "You went to an Elvis concert?"

The elder Hunter leaned in close to tell Sam a secret, "Elvis was a shifter…didn't you ever wonder how he could change body shape that much? Thin, fat, thin, fat…anyway, let's just say that bullshit of him dying on the can was a lie. Bobby shook his head sadly, "I'm only glad I wasn't the one who had to take out the King."

"Oh my god, Elvis was a…"

"Shhh, it's just between you and me. Dean would flip his lid if he knew the King of Rock and Roll was a monster. It's a shame; the guy was good to his mama and a real talent." Bobby lifted his glass toward the heavens, "you had a good run."

Sam gave a solemn nod, "I promise not to tell."

"Hey Sam, wanna go make out?"

Sam turned to find Kelly, a cute Omega from the Sisterhood, coyly twirling a strand of chestnut hair around his finger. The guy was the almost the age as Dean and Sam bet he knew his way around a tongue kiss. Sam, naturally shy around girls and Omegas, hadn't approached anyone since Alfie moved away and he really could do with some kissing.

"Oh boy, do I!"

They ran off hand in hand to find a private spot.

….

Dean cut the huge cake shaped like the Impala and doled out slices until Scotty took over for him. He made sure Gracie got the piece with the license plate. She sat on her daddy's lap and the two shared the cake. Grace had forgotten about the monster from before, thinking it was all something she saw in her sleepy time dreams. All that mattered right now was how much cake she could shove in her mouth at one time.

Lucian stood just a few yards away and waited until the little girl noticed him. He gave her a toothy smile than ran his thumb across his throat. The vampire enjoyed terrorizing the girl.

She immediately pointed him out to her dad, "masure."

"Where is the monster, Gracie?"

Lucian had already vanished along with his brother and one of the guests.

He searched the crowd, carrying his daughter so she could point out the monster but couldn't find it. Castiel alerted Dean, Sam and Bobby Singer. Some guests had already left and there was no way to pinpoint the monster.

…

The twins took their prey to the nearest beach with promises of an evening swim and mind blowing sex. After romping in the gentle waves beneath the full moon, they fulfilled the promise of sex.

Dimitri chose an Alpha so he and his brother could take turns riding him before hunger drove them to kill.

Kyle couldn't believe his luck, scoring two beautiful twin brothers. They were a fantasy come true. People at the party had a difficult time determining what exactly the brothers were. Alpha, Beta, Omega, there was no distinct scent to go by or mannerisms to judge. It was as if Lucian and Dimitri were creatures unto themselves but as it turned out, one brother was Alpha and the other Omega. Kyle could only imagine what the pair got up to in the privacy of their own home.

Kyle fucked the Omega first and now the Alpha was riding his ass gripping the shaft inside him, Dimitri bounced enthusiastically. Dimitri never took his eyes off Kyle and his brother who was sucking the tender skin on the teenager's neck as he waited for his brother's orgasm.

Dimitri felt it, the hot coiling in his belly as he prepared to shoot his seed, "Lucian, now."

On his brother's command, Lucian bit down directly over the victim's windpipe, effectively preventing any sort of scream. With a single jerk he tore open Kyle's throat, leaving behind a gaping wound. As the life force quickly drained from the teen, the brothers descended on the wound so as not to waste a drop.

As his heart slowed to a stop, the last thing he heard was the sucking and snarls of what he thought were fantasies come true.

…..

Castiel woke to the sounds of Dean smacking his lips and the sight of a piece of Impala cake the size of a dinner plate on the Omega's lap.

"Breakfast of champions, I see."

Dean held out a finger covered in frosting, "Don't knock it till you tried it." When Cas sucked the frosting off the digit, Dean smiled. "After this I'm gonna eat some left over fried chicken."

"Don't nag, don't nag, don't nag…" Cas stopped himself from saying what he really wanted, "Protein is healthy for the baby," "even though it's soaked in saturated fat."

"Dean, do you think Grace really spotted a monster last night? She seemed very upset."

"Maybe, it wouldn't hurt to go over the guest list and try to pinpoint any weirdoes or strangers, though honestly, it could anyone. You wouldn't believe what walks among us…friggin' freaky. The trouble is, if you think about it too much you'd never leave the house. Anyway, Bobby's not leaving for a day or two so we've got a seasoned Hunter on our side. If there's a monster, we'll sniff it out."

…

Scotty answered the door and found a man and woman standing there and both looked as if they'd been crying.

The woman handed Scotty a photo, "Mrs. Novak, our son Kyle was at Dean's graduation party last night but he never came home. Do you have any idea where he is?"

Scotty looked down at the graduation photo of the young man, "I recall him here but I honestly can't say where he is." He gestured for the couple to enter, "Come in, I'll get Dean and see if he knows anything."
