Posting with my other Serra/Star fics just to keep them all in one place, but this chapter is unrelated to the previous two. This is a standalone story and a Vampire/Werewolf AU. Proposed by and dedicated to Taboo Sho.

Chapter 3.

Love Conquers All

Serra's fangs ached.

With a grimace, she brought a hand to her mouth and parted her lips, using her thumb and index finger to rub each elongated tooth slowly, massaging a bit of the pain away.

It'd been a while since she'd last fed, and the hunger was starting to become irritating in the pit of her stomach. Her semblance dictated that she didn't require the same amount of sustenance as other huntresses, nor did she require such things as frequently.

But once she'd turned fifteen, things had gotten a bit more complicated.

She was born of two vampiric mothers, after all.

Once she'd awoken as a mature vampire, she required blood at least once a week if she wanted to keep herself strong and healthy.

And ever since she'd met her partner Star, she'd refused to drink from anyone else.

Star was a purebred werewolf, with the tall, pointed brown ears and thick, messy tail to show for it. On a full moon, she could transform fully into a wolf if she so desired.

Unlike vampires who typically awoke at the age of fifteen or so, werewolves were capable of their abilities a few years younger.

Serra could still recall the very first night she'd watched her partner transform.

Star had been scared at her first attempt, shedding her clothes as the fur crept along her entire body, her long brown hair molding together with her skin to become fur. She couldn't speak the same tongue as Serra in that form, and yet the older girl could understand everything she'd meant to convey.

Star had quickly learned how to control her wolf, and transformed back to her human form at will, with only her ears and tail still visible. She'd rushed forward to promptly hug Serra, exclaiming her excitement, leaving the vampire sputtering and demanding Star put her clothes back on.

It had been several years since then...

The memories brought a smile to Serra's lips, but the prick of her fangs against her bottom lip reminded her of her present predicament.

From where she sat on her bed, she gazed out her window and up at the darkening sky. There was an awkward feeling running through her veins, the greatest indication that she needed to replenish herself and soon. She tried to hold out as long as she could, knowing Star would be busy with homework until nighttime.

Serra laid back on her bed and sighed, closing her eyes and dozing for a few minutes until she heard the growl in her stomach. It was a sound food wouldn't help her get rid of.

So she reached out, following her invisible connection to Star – the one that had been formed the first time she'd drank from her, connecting them as partners on a spiritual level. It was almost as though their auras had been linked together, and when either focused their energies hard enough, they could call out to one another and communicate.

Serra located Star's link easily and sent her thoughts to her.

Hey, partner. If you can... could you stop by for a visit tonight? Sorry it's such short notice.

She reopened her eyes a few minutes later and slipped off the bed, going to her door to call out to her mothers and brother that she planned to have Star over. They never had any issues with the werewolf girl or any of her family visiting, but Serra just wanted to make certain they knew she'd be barging in before long.

And it really wasn't a long wait. Serra knew she shouldn't have been so surprised when she heard the playful tapping on her window.

Heaving a sigh, she went to the glass and pulled away the curtains to find a familiar face peering in.

Star was grinning widely, her wolf ears and tails flicking and swishing. The little clip of her namesake tucked into her bangs was shining in the moonlight, and the breeze blew her hair softly.

Serra pulled up the window and rolled her eyes as her partner scrambled in.

"Serrrraaaaaaa!" Star all but threw herself at her partner, locking her in a tight embrace that left the older girl breathless.

"S-Star! Guh-" Serra clawed at her back, trying to pry her off. "God, we're on the second floor! I know you're a wolf and all, but you should be more careful! Don't just cling to the side of people's houses in the middle of the night!"

"Aw, but you know I'm fine, see?" Pulling back, Star grinned again, her fluffy tail wagging back and forth behind her. "I rushed over here as fast as I could when I heard you calling! My partner comes first!"

"Are you sure you weren't just avoiding unfinished homework assignments?"

"U-Uhm..."

"Star-"

"I'll do them later!" she whined, her ears flattening as her eye widened and watered.

Serra grimaced; that was one of the hardest parts about her partner's being a werewolf – literal puppydog eyes, and Serra could never say no or be upset with her when she pulled that look.

In the end, the vampire resorted to a growl.

"You'd better finish your work..."

"I will! Promise!" Star quickly hooked her pinky finger around one of Serra's and gave a squeeze. "But for now..." Her voice took on a slightly more serious tone, her blue eyes shimmering in the dim lighting. "For now, lemme make sure you're okay. You haven't drank from me in almost a week, after all. Unless-!" She gasped dramatically. "You've been cheating on me? Drinking from someone else? Serra, I thought what we had was spe-"

"Would you shut up?" Serra darted forward and pressed a hard, fast kiss to Star's lips to chide her, but being careful not to bite her – no matter how badly she wanted to, for various reasons.

Serra pulled back a few seconds later. "You know I could never drink from anyone else even if I wanted to. Which I don't," she growled. "Even just walking by people if I smell their blood on an open cut, it just... ugh, it's gross. I can't stand the scent of anyone else's blood on the roof of my mouth. Besides..."

She bore her gaze down into Star's, holding the eye contact as she watched the smile spread across the werewolf's lips.

"Besides... I would never dare to drink from anyone else other than my partner. My life partner."

The bond they'd formed together in the past wasn't one they could break, but it wasn't one either of them wanted to break anyway. They'd never need or want anyone else.

At Serra's words, Star felt her chest swell with joy and she wrapped her arms around the older girl and squeezed her tightly.

"Thanks, Serra," she murmured. "It's always nice to hear you say things like that."

Serra returned the embrace properly this time.

"I'm glad."

A moment of silence drifted by, and the moonlight cast darker shadows into the room.

But it wasn't much longer before Star's acute hearing picked up on Serra's labored breathing. She pulled away and looked up to find her partner almost panting, the gleam of her fangs catching the silver light.

"Hey, you should drink now," Star hummed.

Serra's vision was beginning to glaze over, turning crimson around the edges from her hunger. She shook her head to keep control of herself, though her grip on Star's shoulders refused to loosen.

"Yeah... but only if it's okay with you. I don't wanna force you..."

"Oh, please! It's fine, Serra! This is why you called me here, and of course I'm always ready to help you out! No come on, let's do this before you keel over!"

She guided her partner to the bed slowly, step by step. And every step sent little shockwaves up from Serra's feet and directly to her fangs, reviving the aching sensation that came after so long without drinking.

Star sat down on the bed and coaxed Serra down beside her, her tail swishing over the comforters in anticipation. Serra swallowed and closed her mouth for a moment before mumbling to her again.

"Make sure you're comfortable. And tell me if I hurt you."

"I know. You're fine, Serra. You won't hurt me, kay?"

Serra always made it a point to warn her every time before she bit Star. The werewolf was both flattered and amused by the concern, as her body was very tolerant to pain due to her nature, and she knew Serra couldn't hurt her if she tried. But just the fact that Serra worried over her so much made Star really happy.

Once she'd gotten enough reassurance from Star, Serra allowed herself to begin.

She slid forward, closer to her partner, and her hands moved up to Star's collar to loosen it. Her fingers pushed the clothing aside, just down to her shoulder.

She could smell Star's blood already, hear it flowing just beneath the surface of her skin. She exhaled a long breath as she leaned forward, and Star felt the warm breath on her neck. The werewolf girl closed her eyes and smiled, waiting for what she knew was to come. A soft whisper of her partner's name passed through her lips, encouragement for Serra to go on.

There were no previous marks on her neck for Serra to go by, as Star's aura healed her wounds very quickly. She kissed along her partner's neck until she'd selected a tender spot. She gave Star a squeeze to indicate she was about to bite, and Star readily braced herself.

Serra huffed once and let her eyelids fall shut as her fangs pushed at the barrier of skin and she finally sunk inside.

Star didn't even flinch at the slight prick anymore – she'd long-since gotten used to that. Having Serra at such close proximity and so intimate was a common occurrence for her now, something she'd grown accustomed to months ago, and something she would only continue to welcome in the future years to come.

Serra whimpered with relief the second she tasted the warm blood pass through her lips, dripping down her tongue and then her throat. She hadn't realized how dry her stomach had been until now when she could finally quench that thirst. Star's blood was an elixir to her, paradoxically rare and yet readily available to her at any time, so long as her partner was willing to share.

Normally, Serra would sip slowly and gradually, but tonight she couldn't stop herself from gulping a bit greedily for a moment.

Star chuckled, locking her arms around Serra's waist and giving her another squeeze.

"Someone's thirsty, huh?" she whispered into her ear.

Serra's only response was a pouting growl.

Star laughed aloud and returned the sound with a playful growl of her own; being she was a werewolf, it was much more convincing, too.

"It's fine. Drink as much as you need~"

Star slowly laid herself down on the bed, keeping Serra in place on top of her, getting comfortable beneath her partner and relaxing on the bed.

Serra never broke the kiss to her neck, and she adjusted herself at present into a better position, keeping her fangs latched into place. The acrid sting in her throat was finally beginning to die down, and she savored a few more sips.

Mixing Star's blood with her own brought them closer together every time, even more so than the bond shared between them with their linked auras. Star's lifeblood and energy coursed through her veins, and Serra longed to provide similar things for the werewolf.

She felt Star relax beneath her, but still, Serra didn't want to take too much from her.

With a bit of reluctance, she swallowed the last bit of blood and withdrew her fangs. She lapped at the two small bite marks with her tongue to clear away the excess blood, and then covered the wounds with multiple kisses, almost apologetically.

"Sorry..." she breathed. "I hope that wasn't too much." She held another kiss to the side of Star's neck and slowly rested her weight against her. Star wiggled happily under her and reopened her eyes.

"Of course it wasn't too much, silly. If it was, I would've said something. You're fine." Her tail crept out to one side and wagged happily, her ears perked tall as her arms locked around Serra's shoulders. Her fingers played through the older girl's long, rustic hair, silky and cool, trailing all the way down to her hips. She enjoyed the sensation of Serra's lips on her skin, kissing up the side of her neck, down to her shoulder, then back up to her cheek and temple.

Serra propped herself up on her elbows for a moment to stare down into the girl's bright blue eyes, shimmering even in the limited lighting. She fixed the star hair clip that had become a bit lopsided before pressing a kiss to Star's nose.

"Thanks, Star."

The younger girl grinned happily.

"Don't mention it, partner!"

Serra would've been content to let her go back home now, or better yet to curl up and fall asleep with her like this.

But of course Star Wukong wasn't so melancholy as to let that happen. Even after sharing her blood, she was still bursting with energy.

Understandable, when Serra considered what night it was. She'd forgotten until now, until it was already too late.

"Heads up!" Star cheered.

With a surge of strength, she flipped Serra over onto her back, reversing their positions. Serra squeaked briefly, her eyes falling shut as she bounced against the mattress.

When she next reopened her eyes, she was met with a cold, wet nose and a long furry muzzle.

Star had transformed completely into a wolf, her clothes lying next to Serra's head in a heap. All that remained were the familiar ears, tail, and those striking blue eyes, as well as the little clip that stuck into the fur above her ear. She was small for a wolf, but still considerably bigger than Serra in this form.

The wolf yipped joyfully and pounced on her partner, licking Serra's cheek repeatedly.

"Ugh, Star! You dork! What are you doing-?" Serra struggled to fend her off, but Star evaded her pushes and shoves, overpowering the vampire with ease.

When Serra struggled, Star found the simplest solution to be to quite literally sit on top of her – and so she did.

She laid herself down on Serra's chest, front paws folded across one another, her haunches pinning the older girl's legs and hips in place. Star's tail continued to swish back and forth behind her, her eyes still bright with delight and triumph.

Even though Serra had regained some strength from drinking from her partner, she was still clearly overpowered by the wolf. She knew when she was beat.

Serra went limp and sighed, closing her eyes as the familiar tongue lapped over her cheek again.

"Fine, fine! You win, Star! Now could you get off me?"

Star cocked her head to one side and pulled back, her tongue lolling out between her teeth as she made a curious grunt.

Then, she willingly got up, relieving Serra of her weight as she stood over her. She was about to step to the side and let her partner up when she felt a rush of air, and the next thing Star knew, there was a pair of arms around her shoulders.

"Got'cha!" Serra cried, throwing the wolf down onto her side, causing the entire bed to shake. She pinned Star down in a vice-like hug, pouring all of her strength into the embrace, so much so that Star whimpered pitifully when she couldn't shake her.

But the wolf quickly rolled onto her back, exposing her belly and barking once softly. Her tail started going again, and she panted, her lips curved into a smile as she looked hopefully up at her partner.

Serra sat back and rolled her eyes.

"Fine..."

She supposed it was the least she could do after taking Star's blood.

The wolf wiggled excitedly as Serra pressed her hands down into the fur of her stomach and chest and started to scratch vigorously. Star whined, one of her back legs kicking in midair as she writhed beneath the vampire's touch.

Serra couldn't help but laugh at the sounds her partner was making, the excited little growls and yelps.

"You're so cute, Star." She rubbed a little faster, her nails curling through the thick, matted fur of Star's pelt. The wolf whimpered again, panting madly before Serra finally pulled her hands away. "Alright, take a rest. Just make sure you put your clothes back on, yeah?"

She turned around for a moment as she listened to Star slip off the bed, the presence of her wolf disappearing as she took her usual form once more and slipped back into her clothes. Serra waited patiently for her to finish.

"Let me know when you're done and- wha-?!" She yelped in surprise when she felt an exuberant tug on her shoulders, and Serra fell onto her back, her head landing in Star's lap. The younger girl was haphazardly dressed, but it was better than nothing.

"Thanks, Serra! That belly rub felt suuuuuper good! You're definitely the best at it!"

To demonstrate her thanks, Star leaned forward over her partner and pressed an upside-down kiss to Serra's lips. Serra relaxed and accepted the contact without a fight; she was getting tired anyway.

When Star pulled back, a yawn signified that she too was a bit spent.

She helped Serra back up toward the pillow and laid down beside her, nuzzling her face into the vampire's collar and holding another kiss to her chest. Serra rested her chin between the girl's wolf ears, feeling Star's thick tail curl protectively atop her hip.

"Idiot..." Serra mumbled. "You said you'd finish your homework."

"Mm, tomorrow..." she drawled. "I'm too tired to go back now. That belly rub was heaven~"

"Fine. But you're going back home at the break of dawn to finish."

"Okaaaayyy."

Star nestled closer to her partner, and Serra tightened her embrace in turn as she let her eyelids fall shut.

"Night then, Star. Love you."

"I love you too, Serra!"

There were plenty of legends that forbade love between a werewolf and a vampire, but Star and Serra didn't care for such things. They weren't scared, intimidated, or even hesitant about their relationship, one that ran deeper than blood and more strongly than aura.

They were living, breathing proof that love conquered all.

A/N: Well, I hope you all enjoyed!
