Blood Moon

Summary:

Several months into their marriage, Elsa bonds with Jack's werewolf side in an unexpected way.

Notes:

Other people write such sweet Jack/Elsa stories and all my brain can come up with is whatever this is… Don’t read if you’re not OK with werewolf/human smut.

I have Jack being affected by his curse for 3 days/month because the moon is typically at 97-100% illumination for three consecutive days.

Work Text:

“Jack? Are you all right?” Elsa calls out as she enters the chamber at the heart of the Bloodstone Manor. 

She shuffles closer to the cage in the center of the room. Like the rest of the place, it’s been long since repaired from the damage Ted and Jack inflicted upon it the night they met. The lights are off, to cater to Jack’s heightened senses, so she peers through the gloom,  trying to spot her husband.

“Have you eaten?” She doesn’t see him, but there’s an empty platter where a pile of steak had been. So at least that's sorted his urge to hunt – if Jack’s theory holds out. “Jack?” she whispers, one hand wrapping around a bar of the cage, “Do you need anything?”

Despite their lengthy courtship and several blissful months of marriage, Elsa hasn’t seen Jack’s other side since that first night. Jack always insisted it wasn’t safe for her, even with the Bloodstone’s power to protect her. But she’d worn him down eventually. When she pointed out that by leaving the grounds every month for his change, Jack was depriving her of a full week’s worth of his company, and not just the three days in which the moon’s illumination altered him, he’d finally - reluctantly - agreed to this trial run. Jack had warned her to stay away, just in case, and she had...for a few hours, though not because of their agreement. She'd meant to check on him as soon as the moon rose. But she’d lain down with a hot water bottle for her cramps and wound up taking an impromptu nap. But she’s now wide awake and deeply curious as she draws closer to the cage. 

“Jack?” she repeats, in a soft, soothing tone. “It’s Elsa, darling. I came to see if you’re alright.”

A low rumbling sound emerges from the darkness. It’s not quite a growl. It doesn’t sound vicious – not like when he'd been battling her step-mother's guards in this same room. Instead it’s almost curious? Almost welcoming? If he were a cat, she’d call it a purr. It grows louder and then Jack is there, glowing eyes seeking her out. 

It’s startling to see him this way, even though it’s what she expected. Jack’s werewolf form is so much taller than his human form. He towers over her easily, even standing slightly hunched like he is. But he is standing, not crouched to attack or run, waiting patiently, as if letting her make the first move. She reaches out her hand and places it ever-so-gently on his furred cheek. Jack closes his eyes and nuzzles into her hand with such affection that it brings tears to Elsa’s eyes. She hadn’t known his other side had such gentleness in it.

“It’s good to see you, darling,” she says, voice thick. His eyes open as he leans further into her touch, seeking her gaze. “Do you remember..” she hesitates, “Do you remember I’m your wife?”

That almost purr sound rumbles through his broad, furred chest again, and one of his clawed hand covers hers on his cheek. Elsa shivers, amazed and touched that her bond with Jack is strong enough to affect this supposedly feral aspect of him. Emboldened by that thought, she very slowly withdraws her hand. She keeps her eyes on Jack as she paces over to the locked cage door. Jack follows, matching her gate with slow steps. Elsa unlocks the padlock and unchains the gate, never taking her eyes off Jack for more than a second or two at a time. He waits patiently inside the cage until she swings the door wide and steps back for him.

“I trust you. I’m trusting you, okay?” she says, remembering when Jack said the same to her.

The last time the werewolf left this cage, it was with a leap that carried him high into the rafters. This time, he steps forward meekly until he’s by Elsa’s side. Then he’s nuzzling and sniffing her up and down, very like a dog that hasn’t been taught proper manners, tickling where his thick fur brushes against her soft skin. Elsa can’t help laughing at his antics, which doesn’t bother Jack in the slightest. He licks a hot stripe along her face and, chuckling, she pats his cheek.

“Yes, alright, I’m happy to see you too. I’m glad it didn’t bother you to be back in this cage when your changed.” 

Part of her was concerned that he’d feel betrayed when he changed. She'd sent all the staff on holiday, just in case he'd reacted badly. It was a relief to see that he didn’t hold it against her. She wonders, once again, just how much of Jack’s thoughts and memories this side of him remembers. Enough, it seems, that he knows that he can trust her. He licks her again, across the pulse point in her neck. Elsa inhales sharply, shocked at the way her body responds to sensation. 

Jack makes his happy rumble again as she breathes out a shaky exhale. He continues rumbling as he herds her over to the long, curving settee by the fireside. She laughs and lets him push her onto it, amused by his dog-like behavior. Jack leans over her, snuffles through her hair and huffs hot breath into her face. She pulls back slightly, still intimidated by the fierce face her love is wearing, even if he is being rather sweet. He just continues his sniffing investigation lower and lower, until Elsa finally yelps and puts out a hand.

“Jack!”

Her werewolf husband looks up at her and then surges forward past her hand to sniff at her crotch again.

“Jack! I’m fine. It’s just... It’s just that time of the month.”

He doesn’t seem interested in her explanation. With superhuman speed and strength, his claws remove her tracksuit bottoms and her period nickers, leaving them in pieces around him on the floor. Elsa gasps, too shocked to do anything but watch as Jack lowers his jaws between her thighs. He grips her tightly in his fur-covered arms and laps at her bleeding fanny hungrily. Elsa’s hands go to the thick fur on his shoulders, gripping tight. “Jack! Jack?” she says, tugging at his fur, feeling scandalized, but he is relentless. Her eyes shut, her head falls back, and a whimper escapes her.

Unable to break free, and rapidly losing her impulse to try, Elsa succumbs to the feel of a monstrously large tongue exploring her most sensitive parts at her most sensitive time. Jack is always an attentive lover, and has spent many hours giving her oral pleasure, but this... this is something entirely different. It’s wild and a little frightening, but she finds that only fuels her excitement. In an embarrassingly short amount of time, she is crying out his name in orgasm, thighs clenched tight around his furry head. 

Even when her legs slacken, and she lays back against the settee, panting heavily, Jack keeps lapping at her, drinking her in. Only after she’s weak as a kitten, a condition brought on by two further orgasms, does he finally pull back, and look at the wreck of her he’s made. Elsa only then realizes that Jack is completely starkers. He must’ve taken his clothes off before he transformed, because not even rags cover his lower body. She catches a glimpse of his transformed cock, huge and strangely shaped, before he’s moving forward again.

Jack braces himself on the settee, and folds his tall body over hers. Elsa feels the hot, blunt head of his erection, getting slick with her arousal and blood as Jack slides it back and forth between her folds. She arches back shamelessly, opening her legs to him, and Jack drives forward. He growls and she whimpers as he fucks into her, stretching her wide. Jack bites down softly on her neck when he fully seats himself inside her, sharp teeth just grazing her skin. Elsa rolls her hips up to meet Jack’s thrusts, head thrown back, letting him ravage her neck and hold her down. His massive cock fills her, and her inner walls clench down around it. When she cums again, he bites down hard enough to draw blood, though not enough to truly harm her. He laps at his mark and she feels his cock pulsing, filling her with his seed.

“Oh, Jack,” Elsa groans, feeling weak and wonderful all at once. This is followed shortly by a startled “No...,” huffed out in disbelief, as the base of Jack’s cock begins to swell, impossibly inside her. Her protest turns into a groan at the feeling of being so stretched out, so thoroughly fucked, and so intensely sensitive. It finally stops growing, forming a knot that ties them together. Elsa’s so aroused that she finds herself quickly adjusting to the new form of intrusion. She runs one hand through Jack’s fur, the other hand drifts to her clit, drawing circles over it, feeling another orgasm build inside. She’s dripping wet around Jack’s knotted cock, fuller than she ever been. Jack rumbles his contentment and laps at the mark on her neck, and it sends her over the edge once more.

Still, she feels relieved when she feels the knot begin to recede a few minutes later. Jack waits patiently inside her, still lying over her, until he can withdraw enough to start fucking her again. Elsa whimpers, not expecting him to continue, but unwilling for him to stop. Already she feels herself clenching down around him, wetness gushing from between her legs. Elsa tangles her fingers in Jack’s fur and pulls hard, as a final orgasm rips through her, making her vision go black and starry behind her closed eyelids. 

She feels Jack’s dick pulsing once again, and manages to gathers her wits, push him out, letting him spray his seed all over her thighs and shirt. Groggily, she pulls it off and wipes off most of the globs, letting it drop to the floor. Jack bends down to lick himself clean, which somehow shocks her, despite the rest of his very animal behavior tonight. When he’s satisfied with himself, he turns back to her fanny, licking every bit of cum from her. Then he curls up around her, satisfied, ready to sleep. Elsa starts to protest, and then decides she might as well not bother. The settee is comfortable enough for someone who often sleeps on the ground during hunts, and Jack’s furred body around her is warmer and more comforting than any blanket. So she lets herself drift off to sleep.

“Elsa! Elsa!” Jack’s urgent voice cuts through her dreams.

She blinks slowly, wincing as she opens her eyes to the bright sunlight flooding through the skylight. “Jack?” she says, confused.

The events of the night before come back to her in a rush, and she sits up with a gasp. Jack is kneeling beside the settee, still completely naked, his eyes filled with concern.

“Elsa? What happened? Are you okay? Why are you down here?”

Elsa reaches out a hand to pull Jack up with her on the settee. He wraps his arms around her and snuggles close. Then a gasp escapes him and he pushes back, holding her at arm's length, staring in horror at her neck.

“Did I… I bite you?” he asks, blood draining from his face. “Oh, Elsa, I knew this was a bad idea. I hurt you!”

He pulls her back to his chest, pressing himself to her in a way that she knows means he’s beating himself up inside.

“No, no, darling, it’s all right. I mean, yes, it is a bite, but it barely broke the skin. Look, see? I’ll go heal it up with the Bloodstone if it bothers you, but I promise: you didn’t hurt me.”

“Elsa, what happened last night? What did I do?

The terror in Jack’s voice hurts Elsa’s heart, and she hurries to reassure him. She wraps her arms around him tightly and speaks low and soft into his ear, “Your wolf side knew me, Jack. You knew I was your wife and… you wanted to mate with me.”

Jack stiffens in her arms, spine going ramrod straight. “Oh, no..”

“It’s all right,” Elsa soothes, “I… I didn’t mind.”

Jack looks at her, doubt and worry all over his features as obvious as his face paint. “How could you not mind? I’m… it... that is a monster I never wanted you to meet again.” 

“Darling, you weren’t a monster. You were kind, if a bit forceful. And you made me feel good. I like knowing that I can be with all parts of my husband. I love all of you, not just the parts that are safe.”

Jack shakes his head. “I don’t deserve you,” he says. “I don’t understand how you can love me – love that part of me.”

“You don’t have to understand, Jack. Just trust me. Can you do that?”

Jack sighs and kisses her cheek. “Yes, dear. I trust you.”

Elsa smiles. “And I trust you with my life.”

They share a chaste kiss, full of sweetness and comfort. 

“We should probably get cleaned up,” Jack notes.

“Are you strong enough to get upstairs?” Elsa asks, remembering that shifting can be a difficult experience to recover from.

Jack nods. “I should be fine. As long as you’re with me,” he adds with a charming smile.

He stands and offers his hand to Elsa. She stands as well, groaning at the trickle of blood it causes to trail down her thighs. Grumbling, she finds a piece of her bottoms large enough to use as a rag. She wipes herself and grimaces. "I could definitely use a wash. And breakfast. And then I want to tell you all about your other side. I think he's more connected to you than you think."

Together they make their way upstairs to start their day.
