A/N- The vampires will be the last story arc for Bittersweet. Chapters ahead with be the pregnancy and birth of the baby followed by a few chapters that will jump ahead 5, 10 etc years in the future to give you a glimpse of the family and Castiel and Dean's relationship. We are very close to the end.

Dean knew Kyle well, they weren't close but he remembered the teen as a nice enough guy and a bit of a geek, at least for an Alpha. Even it Dean had known something he wouldn't have shared it with Kyle's' parents since this had the stink of something supernatural written all over it.

Bobby and his family joined the family for brunch the next day. There was discussion of what could have taken Kyle.

Bobby took his hand and messed up Grace's head of dark blonde curls, "Grace, do you remember what the monster looked like?"

She bared her teeth, or what there was of them, and let out a little growl.

Sam suggested a werewolf but Bobby didn't think so. "They don't have the composure to blend in that long in a crowd of potential victims. I'd say vampire, the ones who'd been around for awhile have a lot of self control. But I might be pissin' in the wind."

Dean went over the guest list, trying to pinpoint the monster. "Vamps are light sensitive. Was there anyone who didn't go swimming or stayed under the cabanas?"

Castiel recalled there were many people who didn't go swimming and stayed mostly in the shady spots. "This is like finding a needle in a haystack."

Sam glanced up from his laptop, "Breaking news, they just found a body at the beach."

…..

Castiel had to admit, he was excited to play an FBI agent along with Bobby Singer. Cas wore his favorite suit, blue tie and trench coat. Before leaving house, the Alpha admired himself in the mirror and thought he looked very official.

Dean glanced at his husband in the rearview mirror, "Cas, you look badass but the name you picked…stupid."

"I think Ellery Queen is a good name. Just because you have no idea who that is, doesn't make it stupid, besides, yours is terrible."

"Uh, no, Frank Zappa is an awesome name, Ellery."

Bobby rolled his eyes at the couple's lame conversation, "Why don't both of you put a sock in it. I have a mind to go in there myself and leave you two ass hats in the car. Dean, maybe you should stay in the car anyway, no one is going to believe you're a government suit."

"No way, I'm not gonna sit here while you guys have all the fun."

Castiel hated to leave Dean out of anything so he tossed an idea out there to see if Bobby liked it.

"Perhaps it could be, "take your child to work day" and you brought Dean along to see how this all works."

The elder Hunter gave a snort along with his eye roll, this time, "Sure, that'll work."

…..

The pathologist examined the three standing before him, noting one of them looked like a teenager who also smelled of pregnancy hormones.

"Explain to me again, why this boy is here with you two?"

Bobby got almost nose to nose with the man, who took a step back to claim his personal space again.

"I told you, it's "take your kid to work day".

"Alright, examine the body but the kid stays out here."

"Fine," Bobby waved toward the door, "give us some privacy."

Castiel blurted out, "I'm agent Ellery Queen."

The exasperated man threw up his hands in surrender and left.

….

Dean poked a gloved finger inside the gaping neck wound on his dead friend, "Vampire, right Bobby?"

"Yeah, that's a vamp wound alright…a real nasty one. This wasn't just for food; whatever did this really enjoyed it and isn't worried about Hunters."

The pregnant Omega's belly rumbled, it seemed Dean was always hungry now, "Speaking of food, can we go for burgers after this?"

Castiel couldn't believe the amount of food Dean was eating this time around, more than when he was carrying Grace, "Dean, you had a stack of pancakes with butter and syrup for breakfast and a side a sausage. Where are putting this all?"

The Omega let out a snicker, "I got two sides of sausage this morning."

That was the last straw, Bobby lightly cuffed the teen's ear, "No one wants to hear about your sausage party, smartass. Lets feed get this kid fed; if his mouth is stuffed with food at least he can't talk."

"Cas stuffed my face this morning."

Cas barked, "Dean!"

Bobby was starting to regret bringing them along.

…

Scotty opened the front door to find Dimitri standing on his doorstep, holding a measuring cup. The young vampire smiled prettily at the Omega, "My brother is baking but he found we are out of sugar. He needs it to finish the vargabeles, it's a traditional Romanian dessert, as a "thank you" for your kind invitation to the party."

The Omega took a second to admire their new neighbor's good looks before answering. After all, look but don't touch, was the rule between himself and Spencer. "Oh, it sounds delicious, what is it?"

"A noodle pudding." When Scotty made a face, Dimitri laughed, "I assure you, it's delicious."

Spencer appeared behind his wife, carrying his sleeping granddaughter with his son at his side. The Alpha was less than happy to find the young man on his doorstep. With a pregnant spouse and children at home, he was on the offense and overly aggressive.

Spencer demanded to know why the twin was there.

"Spencer, be nice. He's here for sugar."

"I just bet he is."

Scotty hurried to the kitchen to fill the measuring cup with sugar and send Dimitri on his way. There was no arguing with Spencer, not until after the baby was born.

….

Everyone gathered together for dinner followed by the noodle dessert dropped off by one of the twins earlier. Scotty had graciously invited them inside but when Lucian spotted the children playing on the patio, he declined.

Later, over a few beers and juice for the Omegas, they gathered around the fire pit to relax and formulate a plan. Alex dozed off on his big brother's lap while Grace and Addy Singer went to catch lightening bugs. Grace was fascinated by the older girl and her long, curly blonde hair. She took to following Addy around like a duckling.

Addy caught a lightening bug in a mason jar then sat down on the lawn with Grace to show the shiny, magical little creature inside.

"Look, Gracie, isn't it pretty?"

The toddler was focused on something else much more important, the two eyes shining in the darkness. She pointed this out to Addy, and in a soft voice said, "masure".

Addy released the lightening bug then stood and moved closer to the quiet street, sure enough, there was something watching them. She knew it couldn't be a dog or a cat; the eyes were set high like a human but human eyes didn't shine. This was something bad, something keeping watch, biding its time before hunting. Addy may have been only seven but she was also Bobby Singers daughter. Her dad never hid the truth of what was really out there to Addy.

Addy picked up Grace and hurried back to the alert the adults.

…..

At dawn, Dean was keeping watch on the couch by the bay window as the neighborhood slowly woke up. Grace was beside him, eyes fixed on the lovely home across the street.

"Gracie, point out the monster to me if you see it."

Most parents, when their child said there was a monster, would reassure said child there was no such thing. Dean was no typical parent so when Gracie said there was a monster, he believed her. Addy Singer was also a reliable witness to the monster and had pointed out the house across the street.

Mother and Daughter waited for what seemed forever. Dean was worried Grace would fall back asleep before the monster was spotted. Castiel brought her animal crackers and milk in a sippy cup in an attempt to keep Grace awake.

Finally, one of the brothers emerged from the house wearing a boonie hat to protect him from the morning sun. He went to the mail box, took what was inside and while walking toward his house, stopped dead in his tracks, and began looking around. He sensed someone watching.

Grace pointed at the twin and with absolute confidence, declared him a "masure." That was good enough for Dean. He thought the twins were creepy and now he knew why.

….

Dean wanted to head right over there and start chopping off heads but Bobby and Sam pointed out how badly that could go in the suburbs. One of them could escape or the noise might alert a neighbor and the police showing up would be a disaster of epic proportions for everyone.

Spencer handed Bobby another beer or brain fuel, as the Hunter called it. The Alpha wanted nothing more than to see the brothers killed, he had a pregnant wife and Sam to protect. "You have to get rid of them, Bobby, not just for my family but the property values would tank of people knew this neighborhood harbored vampires."

The grizzled Hunter let out a snort, "You're kiddin' right?"

Sam wanted to be taken seriously, especially by Dean and contributing would help him look less of a kid and more of the strong, young Alpha he really was.

"I think we should have someone lure them to the beach, someone they showed interest in at the party, and use this person as bait. The some of us can wait there for vamps there and the others can follow them to the beach."

Bobby was impressed, he clapped Sam on the back, "I like it, good thinking kid." Sam was glowing from the Hunters praise.

Dean wrapped his arm around his little brother and gave him a smooch on the forehead, since he was pregnant; Dean was more affectionate than usual. "I love that big, beautiful brain of yours, Sammy. Maybe the bait could say it's a beach orgy, that way they won't want to feed until they get there. You know, the promise of more food."

Bobby had his concerns, "These vamps are from the old country, I bet they've been around for centuries not decades. The Nestor brothers may look young and pretty but that only hides their strengths. A vampire around that long is a tough kill let alone two, both are seasoned hunters."

Now Castiel was worried, what if Dean or Scotty wanted to volunteer? They were both fearless. "Dean and Scotty are out, Sam is too young, Bobby is too old and sorry dad, but you're too old for them. Who can we get to act as bait? It needs to be someone attractive, young and brave."

All eyes landed on Cas.

…..

Castiel stared at the embarrassing image in Scotty's full length mirror, "I look like a prostitute."

Scotty finished applying the kohl liner around Cas' vibrant blue eyes and took a step back to admire his work. "That's the point; you need to look like a wanton whore." The Omega couldn't resist, he pinched an ass cheek peeking out the bottom of the homemade denim booty shorts, "I'd do you in a heartbeat…I mean if I wasn't married and your step-mom."

Cas plucked at the skin tight white tank top that showed off his dusky nipples and tapered waist, "I feel so cheap and tawdry."

When Dean finished taking pictures for his spank bank and getting in a few gropes, he cracked his Alpha on the ass and told him to go lure some vamps.

Castiel declared romance was dead.

….

Lucian peered through a crack in the curtains as soon as the motion light went off. He was delighted to see delicious Castiel Novak in scant clothing, wiggling his pert ass up the sidewalk and right to their front door.

"Brother, come see, something tasty has been delivered."

Dimitri answered the door sans clothing. Over the centuries no one ever accused Dimitri of being shy. "Castiel the teacher, tell me, what brings you to our doorstep dressed so provocatively."

Cas averted his gaze from the tumescent cock pointing in his direction, "I'm returning your noodle dish." He thrust the porcelain vessel toward the vampire.

"Lucian, come here, Castiel is just returning your noodle dish."

Castiel felt the urge to bolt when the other twin appeared next to his brother, clad in boxers and a lascivious smile.

The vampire stuck out his bottom lip in a pout, "Oh, and here I thought you came dressed as a strumpet because you wanted us in a carnal way."

"Come on Cas, turn on the hotness Dean is always talking about…" He lifted his tank top slightly revealing his cum gutters and belly button, "To be honest, I did come here for other reasons than this noodle dish."

Lucian, the Omega of the two, ran his tongue over his lips as he thought of riding the teacher and then feasting on his blood. Then he had another thought, Castiel was so attractive maybe he'd turn the young man to be an additional mate and to grow their numbers.

"I-I was wondering…would you be interested in a beach orgy? I've organized one at the beach this evening because that's what I do; arrange orgies and having intercourse with many attractive people." "That was smooth, Dean would be so proud of me…"

Dimitri arched a dark, sculpted brow, "Oh really? From your wife's show of jealousy the other evening, I have my doubts about this orgy. It seems he'd rather gut anyone who touched you that allow you to fuck strangers."

Castiel went full Alpha, "I don't care what Dean feels, he's my Omega and in our relationship my word is law. I'll have intercourse with anyone I please and in any quantity. In fact, Dean will be there and I'll let you both have at him if you like. He has no say in this."

The twins looked at each other, unspoken words exchanged between them. Cas could feel the trickle of sweat rolling down his forehead as he waited for them to decide. He was worried they'd declare him a liar, drag him inside and kill him before anyone could get there in time to help.

Dimitri finally spoke, "Agreed, we will join you if the participants are up to our standards. Who will be there?"

"Benny and Javier will be joining us. You remember Javier, the sweet little treat you were hitting on at Dean's graduation party."

The brothers smiled in unison, recalling the cute Omega.

Lucians smile changed to a frown when he recalled Benny, "The big one is just barely attractive enough for us but the little one will make up for that."

The vampire lean in and sniffed the sweaty Alpha, "You stink of fear."

"I've never had twins before."

"I see. Has anyone ever told you, Castiel, that you word things strangely?"

"Actually all the time."

Castiel gave them a cheery wave before making his escape, "See you later for intercourse."

….

Bobby, Sam and Nicky waited at the beach, each armed with freshly sharpened machetes and arrow rounds laced with dead man's blood.

Dean and Castiel followed the brothers that night, to the same beach where Kyle's body was discovered, a fitting place to kill two monsters.
