PLEASE NOTE I will again not be using the Supernatural standard for this monster. If you've red one of my previous stories for another fandom, 'Even a Guarded Heart Beats', that's the style I'm using. It's kind of my own take on a vampire and similar to my setup of werewolves in my previous chapter.

Chapter two: Vampire!Alpha! Castiel and Human!Omega! Dean. Smut with a bit more plot than last time. :)

Enjoy!

Castiel pushed the overlarge front door shut, bracing both hands on it with a sigh. It had taken way too long to get them out, in his opinion. It was a downside of being a member of the family running a Vampire clan. Even if he was the youngest, there were still inter-family politics and meetings and other social obligations he hated paying. Still, it could be worse. Tonight it had just been an informal meeting in his parlor, most of the others sipping on wine or a favorite blood type.

The Alpha turned away from the double doors that was the main front entrance to his home, almost two-story things that his mate never used. Dean had been reluctant enough to move in with him, and while Castiel himself found the oversized house to be too much, there was an image to maintain. Even so, it did afford him a personal library, and he was able to give his mate a large garage where he could take care of his beloved Impala and work on various other cars.

Thunder was starting to rumble outside as he climbed wide stairs running up from the main room, clouds cutting off what little sunlight was left. By the time he made it to the master bedroom he shared with Dean, the heavens had opened up, rain pelting the roof as thunder continued to rumble. He shed his trench coat and changed out of his suit, putting on more comfortable clothes. Not that he thought he'd be wearing them long.

As he stepped out of his closet, the door to the bathroom swung open. Dean came out of the steam filled room, running a hand through his damp hair, basketball shorts slung low on his hips. Castiel paused, taking a moment to enjoy the sight before him. Not for the first time he appreciated how casual Dean could be about his dress code. Lightly tanned skin, broad shoulders, and just the right amount of muscle. Not so much he was bulky, but not flabby either. It didn't hurt that there were several places where dampness still clung to his skin, glistening as lightning flashed through their windows.

"Hey. They gone?" Dean didn't mind most monsters, actually. He just didn't like the ones Castiel had to deal with any more than Castiel himself.

"Yes."

Dean leaned against the wall, folding his arms. "What was this one about? More blood runs, how to dis the werewolves next door?"

"The latest alternative blood routes, and what to do with rowdy ghouls," Castiel corrected.

The families might not always agree, but they did have a common value: secrecy. You couldn't do that, not with so many monsters in one city, if you didn't control feeding. The other families had their own methods, but vampires simply helped themselves to blood trucks. Blood had a short shelf life and countless bags were thrown away, they simply took what no one would miss. But they also had to change up where they got it from to be less conspicuous.

"Seriously? It took you guys three hours to work that out?"

Castiel wandered closer, still admiring the view as rain poured down outside. Judging by the pink in his mate's ears and the sudden reluctance to meet his gaze, he'd noticed. "They have to chat and argue and complain. It's enough to give a person a headache. On top of that they went through most of my blood stash."

"Why do you care? You never use that stuff."

"I know, but it's still rude. Never mind the fact they have a low opinion of humans."

"And you wonder why I avoid them like the fucking plague every time they come around."

The Alpha chuckled. He stopped inches away from his Omega, reaching up to cup his chin. "I don't wonder." He lightly kissed one cheek. "If I had my way, I'd join you." The next kiss was closer to his mouth. "They're fools who look at humans and only see food or tools." He had to correct his aim, so he would kiss the corner of his mouth when the Omega tried to catch his own lips. "Patience, Dean," Lightly pecking his mate's lips he inquired, "Don't you remember? It makes things better in the end."

"Screw patience," the Omega growled. He grabbed the Alpha and yanked him into a real kiss.

Castiel obliged him, returning the kiss eagerly, slowly drawing his mate back towards their bed. The Omega fumbled, yanking his shirt over his head as they went, gasping as a rough kiss was turned on his neck. His feet stumbled, and Castiel's lips curled up as he worked.

Only once a suitably blatant love bite was visible did Castiel pull away, pushing Dean back onto the bed as thunder rumbled. He grabbed the basketball shorts, yanking them down his legs and tossing them aside. He paused long enough to shed his own pants before crawling over his breathless mate. The moment he was on top of his Omega, long legs hooked around his waist, hands latching onto his shoulders.

The vampire kept up a continuous rain of heated kisses, leaving his mate gasping for air and not at all unhappy about it. He shifted his weight, freeing one hand to trace a collarbone, working south. Fingertips brushed a hitching pectoral, traced down his stomach and caressed his side. He kept the touch light, enough to taunt and plenty to make his mate tremble. Only when he'd coaxed a pleading whimper from the human's lips did he hook a hand under his thigh, hitching him a little higher and shifting his weight.

Curious, and wanting to taunt his mate a little more, Castiel slid his hand down, until his fingers found what he was looking for. Dean's breath hitched, his face turning pink as the Alpha's fingers found warm slick. A smirk curled at the Alpha's lips. Even now, something he wrote off as natural never failed to embarrass Dean. Not that it interfered with his intense enjoyment of sex, of course.

"Are you ready for me?" he rasped, fingertips stroking the throbbing pucker, already dripping slick. "Needy Omega. Mine."

"Damn it Cas." It was half growl half whimper, making the Alpha's lips curl up in a true smile. "Just fuck me already!"

Castiel obliged. He slid inside his mate in a single, smooth motion as a particularly loud crash of thunder hit, partnered with a flash of lightning. Hardly intentional, but very theatric. Green eyes flew wide, a gasp tearing from Dean's throat as his head fell back. The vampire moaned, feeling his fangs drop as tight heat engulfed him. Short, dull fingernails dug into his shoulders, his back arching as Dean bucked beneath him. A growl rumbled in his throat as he pinned his mate to the bed, and he dipped down for a dominating kiss, fangs and all.

Dean quieted almost immediately, submitting to the kiss with a soft moan. The lust broiling in his stomach finally boiled over, and Castiel's vision went white, focusing entirely on Dean. It was the final piece that made this one human so wonderful, so amazing. He was disliked not having control, was very self reliant, particularly for an Omega. More than once he'd gotten into trouble for refusing to submit to Alphas, for successfully asserting dominance of his own. Yet in bed, it was the other way around. Yes he might make Castiel work for it, depending on his mood, but he always gave in, always submitted entirely. He loved it, needed it, got off on it more than anything else.

Abruptly Castiel rocked forward than back again, driving hard into his mate, making him gasp. When his grip tightened, the vampire reached around with both hands, slamming the Omega's wrists down onto the bed, pinning them there. Dean struggled, if only for a second. He needn't have bothered, the Alpha was stronger than him any day of the week. He lay still, restrained, completely at the Alpha's mercy. Just the way they both liked it.

Castiel took his time, not rushing, delighting in every needy whimper and pleasured moan, audible even over the maelstrom raging outside. Oh gods he loved being able to do this, reducing Dean to a puddle of happy ecstasy, to wring such a variety of sounds from his mate's lips. He considered pausing, fetching some of the restraints, but thought better of it. Maybe next time...or later, if they had the energy for it. Dean certainly had stamina, another of his many good qualities.

"Ca- Cas, Cas, gods Cas, don't stop, don't stop, don't- damn it, don't you stop! Please, Cas, I- mph!"

The vampire brought his mate to the very brink, then stopped, waiting for him to fall away from it, dipping down to kiss him and swallow his protests. It drove Dean mad, yet he never fought to take back control. He lay still, trembling and sluggishly returning the kiss. The second time Castiel did this he was less compliant, biting the Alpha's lip only to yelp as it earned him a hearty swat on his backside.

"Shh," Castiel crooned, kissing him tenderly. "Hush, my Omega. Say you're sorry and you'll have what you want."

"You've gatta be kidding me." It didn't have the usual force behind it though, said more out of habit than defiance. He pressed his head back, closing his eyes. "Cas, I...I'm sorry, just please don't stop again."

Castiel smiled, fangs still out. That time, he didn't hold back, driving them both to that precious edge. Dean's arms and shoulders strained against his grip, muscles bulging, head thrown back and turned to the side, exposing his neck, offering it. He didn't say anything, he didn't have to.

That time, the Alpha didn't stop. He had the pleasure of watching Dean's eyes roll back as his orgasm hit moments before the Alpha's own. He gasped as it slammed into him, and his head dropped. The combination of intense pleasure and a sharp pain as fangs slashed his neck pried a strangled, pained noise from his throat, but otherwise all that came through his lips were pleasured pants.

Castiel latched onto the short cut, running his tongue along it to get his saliva into Dean's bloodstream before he started sucking. The Omega began to outright tremble around him as the vampire started to draw blood, gulping down mouthfuls of the hot liquid. Blood always had a faint, bitter tang to it, but it was only the under taste. The rest always depended on the person, but only if it was fresh. A downside of drinking blood bags. Dean's blood had an oddly sweet scent, something that carried over into its taste. The only thing Castiel could ever compare it to was chocolate and sweet wine, a bizarre combination but one he never tired of.

He had to be careful, he knew. He couldn't take too much. No matter what the situation, he always had to count the swallows so he wouldn't drink too much. All it took was one mistake, one time of pulling away to find Dean pale and unconscious in his arms for him to never forget. It had been the first time he'd drunk from the human, and he'd panicked, but thankfully he hadn't taken so much Dean had needed a transfusion.

Once he'd reached the cutoff number, and it wasn't just his sexual need that was sated, the vampire drew away. He ran his tongue over the cut again, this time to seal it. A vampire's saliva had several very useful qualities, namely healing properties as well as being a potent drug. As far as Castiel had been aware, it was a sort of anesthesia, something Dean readily confirmed. The Omega described it as a numbing agent wherever Castiel was feeding and ecstasy-inducing everywhere else. As an added bonus, if they put an extra dose in the bloodstream the human wouldn't remember anything afterwards, not that Castiel did that. Dean enjoyed it too much.

Slowly, the Alpha slid out of his mate, rolling onto his side next to a still panting Dean. For a minute they both just lay there, catching their breath. Both of them had an extra buzz, brought on by the feeding, on top of the high of an orgasm. Vaguely Castiel counted backwards, a little worried to note he hadn't fed in almost a week. He tried to do it twice a week, so he wouldn't need so much. Dean had certainly not complained, but they just hadn't had time. He'd have to make time. Not just for the blood, but for his mate.

"Would you like me to take you to dinner this week?" he asked abruptly.

Dean gave a breathless chuckle. "You're stubborn about that whole quality time thing, huh?"

"You're my mate, I should be."

"Fine, but no fancy restaurants. You should know by now the monkey suit thing isn't me. I want pizza and the three stooges or something. Maybe we can grill out one night."

"That sounds nice." He lifted an arm, reaching over to brush his fingers through his mate's hair as lightning lit Dean's face. "I've been neglecting you."

The Omega groaned, rolling over until he straddled his mate's torso, hands braced on his chest. "No, you haven't. I haven't exactly been around much either." He hesitated, then added uncomfortably, "Actually I, uh...I've kinda been dodging you. A lot."

Castiel frowned. "I don't understand. Why?" He counted back even farther, realizing he'd only been feeding from Dean once a week for almost a month now. "Is something wrong?"

Fear settled icy claws in his belly. What had happened? Had he made a mistake? Was Dean pulling away? His mate was a human, but he wasn't. It was one of the reasons other vampires were reluctant to mate them. Vampires were born, they had extended if somewhat normal life spans, so it wasn't that. It was that when they took a mate, they were bound to that person for life, body and mind. There was no divorce or infidelity among vampires, and if something happened to one the other would either go mad or follow them to the grave. Castiel had known this when he'd taken Dean as his mate, but only once he was sure. What's more, the human knew.

"Not exactly. It's just that we never talked about it, and I don't..." Dean closed his eyes, jaw tight. "How do you feel about kids?"

Castiel frowned. "Kids? What does that have to do with this?"

"Just answer the question. Please?"

He had no idea where Dean was going with this. It really hadn't been something they'd ever thought to talk about, or at least he hadn't. That said...Dean liked children. He knew that. He might not advertize it, but he was good with them, and they liked him. He'd seen it.

"Do you want children?" he asked uncertainly. "I wouldn't be opposed to the idea. But you understand they would be a hybrid, correct? They would require blood, they would have a human life span but their speed and strength would be increased."

"I know, I know," the Omega snapped, waving it away. "You still haven't answered the question. How do you feel about kids? I mean you avoid them whenever you can, you never mention them, and you freaked when Lucifer dumped Lilith on you for a day."

Castiel winced. "That is hardly fair. I'm not...I'm not good with children, he knew that before he dumped an infant with a fever on me with no prior warning."

The Omega's shoulders tensed, and he took an unsteady breath before asking, "So you wouldn't want any of your own?"

"I didn't say that," Castiel protested. He sat up, pushing Dean off him so they were both upright. "I said I'm not good with children, as in other people's children. It's my understanding things are different if they're your own. Why are you so intent on this all of a sudden? If you want them so badly, why don't you just say so? You're normally more direct than this."

Dean wouldn't meet his eyes. "It ain't that. So you'd be okay? If we had one?"

"Of course, Dean." He pressed a hand to his mate's cheek, tipping his face up. "We can try, if you like. Vampires don't need a heat, you'd just have to go off your birth control pills."

The Omega cleared his throat, pulling away. "Yeah, uh, that's the thing. You didn't mention that when you insisted I go on the pills."

Castiel frowned. "I don't understand."

"I forgot, alright? I...missed a week...or two." At Castiel's expression he protested, "I didn't know it was that important, Cas. You should have told me. Yeah I got into the habit but I forgot them when we went on that trip to the Rockies and it was downhill after that."

"Why didn't you tell me?" Castiel demanded.

"I didn't think it mattered!" Dean snapped. "Damn it Cas you never told me. I've been barfing every morning for the last two weeks like clockwork. I passed out putting a new engine in that Mustang and I've been craving cake with anchovies. If it was pie I might not care, but it's cake."

Castiel froze. It took a long minute after Dean's rant before he slowly asked, "How have I missed you being sick every morning?"

"It's more like midmorning, and it only lasts half an hour. The one time it happened when you were around I told you I had food poisoning. You okay? You don't look so good."

Slowly, the Alpha fell back onto the bed, staring at the ceiling. "You're pregnant," he whispered.

Dean bent over him, a bemused expression on his face. "Yeah. So you're cool with it?"

The vampire sat up abruptly, grabbing his mate by the shoulders so they wouldn't smack into each other, then embraced him. "You're pregnant," he repeated, holding him tight.

"Cas, a little breathing room."

"Sorry." He hurriedly released his grip, leaning back to look at him. Namely his stomach. It still looked normal enough, but then he'd still be in the first trimester. "You're sure?"

"Pretty damn sure."

Slowly, the Alpha felt a smile start to spread across his face. He might not be good with children, but the thought of Dean having one didn't terrify him as he thought it would. Well, the idea of having a screaming pooping infant on his hands was terrifying, but not having one with Dean. They had made it, them. It would be theirs. A child. A real child.

"So you're okay with this?"

Rather than answer, Castiel yanked him into a kiss, not letting him up until every muscle had gone limp under his hands.
