Halsin crouched over Yvaine’s unconscious body in the Underdark, trying not to panic as his hands glowed golden with healing magic. Astarion was nearby, pinning the responsible party to a wall by way of his arm across her throat and a knife to her chest.
“What did you do to her?” he hissed, his red eyes consumed with rage. He pushed the knife in just enough to start drawing blood. The scent hit his nostrils, and he leaned in closer, inhaling deeply. The drow winced at the pain. “I won’t ask again.”
“Just a hex! I swear it...she didn’t want to agree to the terms of our deal.”
“You changed the deal at the last minute. Of course she was going to say no, you pathetic excuse for a drow. If any harm comes to her because of this, I will cut your arms off and throw you into the river,” he said with an irresistibly charming menace. “Or maybe I’ll just do it now.” The drow paled beneath his grip as his arm pressed harder into her windpipe. He laughed at her futile struggle to be free; she was no match for his strength. As she choked for air, Astarion smirked as the light began to leave her eyes. She had hurt Yvaine and could have potentially killed her. She wasn’t worth keeping alive. “Perhaps I’ll send you back to Lolth.”
“Astarion,” Halsin called, snapping him out of his bloodlust. “She’s breathing! Leave the wretch. We need to get her to camp. Now. ” With an annoyed huff, Astarion released her. The woman dropped to the ground, holding her throat and gasping.
“You got lucky, worm. Pray that I don’t find you again,” he said, spitting on her before striding over to Halsin and Yvaine. The large elf had picked up her unconscious body, and the trio made their way to their makeshift camp. Once there, Astarion made a nest of blankets and pillows for Yvaine in their tent. Halsin placed her gently down, worry painted across his face.
“Her skin is on fire... I don’t know what to do. I-I’ve poured so much magic into her to keep her stable,” Halsin said, his voice quiet. He wouldn’t lose her, not when they'd come this far together. “Oak Father, please protect her.” Halsin laid down next to Yvaine and wrapped a massive arm around her waist.
“Do you think she’ll be alright?” Astarion asked, joining Halsin on the other side of her.
“She will pull through, though, I don’t know what kind of magic she was hit with. It could be anything. I’m not too familiar with drow magic.” A shadow darkened his eyes. “Not…this kind anyway.” Halsin turned his thoughts away from the events of his misguided youth and focused on his wife, who lay unconscious between them. Astarion noticed the change in his demeanor and laced his fingers with Halsin’s, understanding that he had also been kept in bondage. He offered a weak smile before looking back at Yvaine and placing a quick kiss on her cheek.
“You’ll be alright, little love. We’ve been through worse,” he murmured, nuzzling against her softness and drifting off to sleep, his hand still entwined with Halsin’s across her stomach.
It was difficult to tell what time was in the Underdark, and Halsin didn’t know how long he had been watching over her before he fell asleep as well, beneath the ethereal glow of the bioluminescent fungus and rocks that surrounded their small camp. An inhuman sound tearing itself from Yvaine’s throat woke the both of them, each reacting in their own way. Astarion was at the ready with his knife, crimson eyes scanning the dim light for enemies, not realizing that the sound came from her. Halsin focused on Yvaine, stroking her face and hair before recoiling when he noticed her begin to shift. Halsin had watched her shift into wildshape so many times before, but this was different. This wasn’t the gold flash revealing the sleek fur of a white-tailed deer that he would playfully chase around the wilds. Her eyes snapped open, revealing nothing but bottomless black pits. Tendrils of ethereal black smoke poured from her eyes, and her skin rippled and stretched. The pair watched in terror and helplessness as she changed. Her bones snapped and reformed, and her joints popped with a sickening sound. She screamed as her limbs elongated and grew larger. Golden fur covered her body, and clawed fingers tore at clothes that confined her. Her legs became more deer-like, ending in cloven hooves and her upper body shifted into something resembling a cave bear. On her head sprouted a large pair of elk antlers, and her entire body undulated as she snarled at the both of them through a mouthful of sharp fangs.
“What do we do?” Astarion panicked, scooting away from her. Halsin stared at her in fear before catching her scent. His eyes went wide, and the color drained from his face.
“Keep her focus on me. Astarion, don’t let her see you.” He quickly cast an enlargement spell on himself to match her new height and size. He partially shifted into his cave bear form, retaining most of his features, so wherever his Yvaine was inside that creature, she would see him. She would know him. “I’ve only ever seen this once before. She’s in some kind of cursed heat, and this won’t relent until she finds release. Unless you think she won’t rip you in half, I suggest you get out of sight.”
Astarion did as he was told and watched helplessly as Halsin darted out of the tent with a speed the vampire had not seen before. Yvaine hissed and chased after him, following the half-shifted bear to a grotto rife with glowing fungi. The bluish glow made her look more menacing, more feral. Halsin skidded to a stop and tripped her by raising a sizable root from the earth. Once she was knocked to her knees, he uttered a prayer to the Oak Father and called forth vines that sprouted from the ground with fervor. They wrapped around her legs and torso, pinning her to the moss. She wailed and tried to claw her way free, but his magic was too strong, and where one vine snapped, two more took its place. Halsin felt his heart crack as he walked around her to look at her face. He no longer beheld the lovely, soft face that would smile at the sight of him, but rather a creature that looked like she had come from the depths of the shadow curse. Her once mismatched eyes now shone with a wicked black malice that Halsin didn’t recognize.
“Oh, my heart,” he said, kneeling before her monstrous form. He reached out and touched her face, and for a brief moment, he thought that she recognized him, until a low, inhuman rumbling growl resonated through her body. He pulled his hand away, narrowly avoiding losing it in her jaws. She did, however, manage to clamp down on his forearm, and the taste of his blood caused her to thrash even more against her bonds. Halsin gritted his teeth through the pain and managed to pop her jaw open with his free hand. “You will come back to me,” he snarled, stalking around behind her. “I am sorry, my dove, but this is the only way.”
Halsin’s ears perked up, and he paused as Yvaine spoke, her voice otherworldly and tinged with bloodlust and something dark and desperate. “Help…me…” she growled, her breathing labored. “Halsin… please fuck me… ” she managed to get out before losing herself again to the hex and to the creature that the drow had turned her into. She knew what had to be done and, through her sheer willpower, broke through, if only for a moment. That was all he needed to hear. His conscience would be clear, and he would be able to ravage her without guilt. Halsin had been in far more precarious situations than this, where his manhood was involved, and knowing that this was for the good of his wife only strengthened his resolve. He knelt behind her and began stroking himself, closing his eyes and breathing steadily as he felt the weight of his length harden beneath his touch. With his other hand, he ran his fingers along the soft fur on Yvaine’s hips, leaving grooves where his claws trailed. This creature wasn’t Yvaine, but the sound that she made as he slid his cock into her dripping entrance was all her. He knew she was in there—she just needed to be fucked out.
Between the enlargement spell and his shifting, Halsin’s cock was easily the size of Astarion’s forearm and just as, if not, thicker. He knew his knot would fill her more than she had ever experienced, but he believed that while she was in this form, she was made to take it all. And he would make sure she did. Gripping her hips tightly, Halsin began to pump his hips, sliding his massive length into her, his pupils blown at the sight of how much it stretched her. The sounds that Yvaine was making could only be described as those of a bitch in heat. Desperate, wanton moans and growls poured out of her maw as he fucked her with reckless abandon, his heavy balls slapping against the backs of her sizable thighs. He would make this up to her later, but right now, this needed to be rough and hard. His claws dug into her hips, drawing blood. He knew that the marks would remain when she changed back and would most likely scar. He hated the idea that he had marred her like this, but he couldn’t help it—he would heal her afterwards. He pistoned his hips hard, pulling almost all the way out before slamming back in with each thrust, and Halsin knew from countless nights of being buried in her that she was close. He could feel the way her walls fluttered and squeezed around his cock, one of the telltale signs. Under normal circumstances, Yvaine would make the smallest whimpering sounds just before her release, but Halsin had to rely on feeling, as the only sounds coming from her were animal cries. Several more thrusts, and his knot began to swell. With a roar of his own, he buried his cock deep within her, his knot expanding rapidly within her tight, dripping heat. He leaned over her as his knot tethered their bodies together, his cum pumping into her.
Yvaine snarled and wailed, chasing her own release, thrashing against the vines that still bound her. Her hips bucked wildly as she remained bound to Halsin, his giant knot stretching her beyond capacity. She felt his torso on her back, and his arms circled her waist as he held onto her, his breathing ragged. After an eternity, Halsin’s knot finally deflated, and he pulled out with a wet pop. He watched in amazement at how much cum leaked out of her. Slowly, Yvaine’s mind began to clear, as though a fog had begun to lift. She focused on her breathing, the size of her body, and Halsin. The painful arousal and bloodlust began to fade. No longer did her voice belong to a feral beast, and Halsin choked back a strangled sob as she heard his name whispered over and over. He had been right about the drow’s hex. Feeling Yvaine’s body begin to shift under his hands, Halsin dropped every spell he cast and shifted back. Once back to his normal size, Halsin released the vines, catching her body before she collapsed to the bed of moss beneath them. He held her close and stroked her hair, ignoring the sickening crunching and snapping sounds of her limbs going back to normal. The golden fur fell away, once again revealing her soft, milky skin and abundance of constellation-like freckles that peppered her shoulders. The antlers fell to the ground, and her face returned to normal, the black tendrils of her tattoo gently sweeping up her jaw. Her eyes were no longer the black bottomless pits of rage, but rather the blue and red that Halsin loved to gaze into.
“Oh my heart, you came back to me,” he said, holding her close and burying his face in her hair. He could have held on to her like this for the rest of eternity.
“Found you,” she said weakly. The change back took a lot out of her, and Halsin carried her back to their camp, where he had discovered that Astarion had created a massive nest of blankets and pillows for her.
Astarion paced around the tent, looking like a nervous wreck. His ears flattened as he heard the tent flap ruffle open, and he felt his heart in his throat as he beheld Halsin carrying Yvaine in bridal style. She looked exhausted, like she was barely holding onto Halsin’s neck.
“Little love, are you alright?” He asked, rushing over to them. He brushed her hair out of her face before his eyes darted to the claw marks on her hips. “You’re going to heal those, you know,” Astarion said without looking at Halsin.
“I fully planned to. Thank you for making this bed for her,” he said, settling down in the cushions, propping Yvaine up between his legs, and letting her head rest on his chest. The feeling of his stomach on her back comforted her, and she let out a contented sigh as the rest of her body sank into the nest that Astarion had made. The familiar golden glow radiated through Halsin’s palms as he rested them on her hips, healing the wounds. As he predicted, they did leave behind small scars.
“Don’t worry, they’re just a few more to add to the collection,” she said jokingly. “I don’t mind, really. And…I’m sorry for...biting you.”
“Biting? Yvaine, really. That’s my job, you know. Also, thank you for not eating me,” Astarion added, kneeling in front of his druids.
“I was never going to eat you!”
“But you could have, and that’s just as bad. I’ll just have to teach you a lesson about hypothetically eating people.” A wicked grin spread across the vampire’s face as he peppered her thighs with kisses, moving each of her legs so they were on either side of Halsin’s. He felt her heartbeat increase as he journeyed further up her thighs. Looking up at her from between her legs, Astarion licked his lips. “I suppose you did just have a harrowing time with that hex, so allow me to take care of you instead of teaching you that lesson. I can already see that our bear has already tended to you as well,” he said, admiring the amount of his cum that left her glistening in the dim light of the tent.
Yvaine’s words left her as Astarion pushed her thighs further apart and licked a slow, broad line up her entrance, grinning against her as she shuddered at the new attention. He placed a kiss at the top of her slit before licking and nibbling at her at an agonizingly slow pace, and he held her thighs when he felt her body tense. Yvaine felt a low rumble deep in Halsin’s chest as he stroked her hair, whispering words of love and promises in her ear.
“Let him take care of you, my dove. You’ve had such a trying evening. Relax and let him work,” he said, crossing his arms around her and cupping her breasts, weighing them in his palms. “Just remember to breathe.” Yvaine whimpered under their touch, needing it more than she had realized. Astarion’s tongue swirled lazy circles around her swollen clit before he drew it between his lips and sucked. Her breathing came in short gasps and breathy moans as she carded her fingers through his silver curls, tugging to urge him closer.
"Astarion, please... ” she whined, trying to buck her hips into his face. He simply shook his head and held her legs tighter, continuing his infuriatingly slow and gentle ministrations. Astarion looked up at her, pulling his mouth away. She watched hungrily as his chin glistened with the combination of his saliva and Halsin’s cum.
“What’s wrong, little love? Don’t like the edge?” A low, wanton sound escaped her when she felt him effortlessly slide three fingers into her.
“I - I need…”
“He knows what you need, my heart. As do I. And you’ll get it in abundance.” Halsin growled in her ear, the sound of his voice only increasing her arousal. Astarion continued, his fingers working in tandem with his skilled tongue, bringing her closer to the edge over and over. Tears pricked at the corners of her eyes, and as she bit her lip, she let out a small gasp, feeling that her teeth never fully changed back, leaving her with fangs slightly sharper than Astarion’s.
“H-Halsin…my mouth,” she breathed. Halsin lifted his hand from her breast and put two fingers in her wet, waiting mouth, groaning lightly as she bit down gently.
“Mmm, we’ll have fun with that later,” he said, keeping his fingers in her mouth while Astarion shimmied out of his pants. With one swift movement, Astarion hoisted her legs over his shoulders and slid his cock into her weeping cunt, earning a high-pitched gasp as she felt his cool skin against hers.
“Always so eager, my pet…” he began to move his hips, folding her against Halsin as much as he could, driving into her folds. The large elf took his fingers out of Yvaine’s mouth and slid his hand down to grip her ass, the slick fingers teasing her unoccupied entrance. Her eyes went wide as she felt Halsin’s fingers playing with her ass, his touch rough but gentle. That, combined with Astarion’s relentless thrusting, threatened to send her to the edge.
“We can’t control ourselves around you, my heart,” Halsin said, low and husky, before biting down on her shoulder. “Do you want us both?” he asked as Astarion hiked her body up, his cock still deep within her. The vampire positioned her perfectly between the two of them, so her ass was lined up with Halsin’s throbbing cock. Quick casting had Halsin’s fingers slick with a clear lubricant, which he stroked himself with before rubbing it on Yvaine’s tight entrance. Adjusting his hips, Halsin pressed the head of his cock against her with just enough pressure to barely breach her.
“Tell us what you want, little love. We’ll make sure you get it,” Astarion said, glancing at Halsin, who simply grinned at him, his eyes growing dark with desire.
“I want you both inside me,” she moaned, her own voice hoarse and breathless. She inhaled sharply as she felt Halsin’s length begin to enter her, and Astarion let out a groan as he felt Halsin through her inner walls.
“Fuck…” he breathed, feeling Halsin’s cock moving within her, sliding against his own. Yvaine wrapped her arms around Astarion, holding onto him as they moved in tandem, filling her completely and providing the sweet stretch that she craved. She choked out a broken moan as they fucked her, each man claiming her and each other. Halsin was careful not to pop his knot into her tight ass as he felt it pulsing, but it was a task that proved increasingly difficult when Astarion leaned forward and kissed him with a ravenous need. Yvaine cried out in ecstasy as she reached the pinnacle of her pleasure, and both men moaned as they felt her muscles clench around their cocks. Under normal circumstances, both of them would have lasted longer than they did, each man driven wild by her words of praise, love, and promises of more. Halsin and Astarion found their own release and spilled inside her, Halsin’s knot resting at her tight entrance while the rest of his length pulsated within.
“How was that, my pet? ” Astarion panted as he pulled out of her and gently unfolded her legs. Halsin slid out of her ass with a wet pop and banded his arms around her chest.
“You do that to me, and you ask me how that was?” She laughed with a sweet, breathy sound. She let them move her body around like she were a doll, positioning her perfectly in the pillow nest and making sure she was comfortable. Halsin got her some water and a small snack while Astarion curled around her body, his fingers gently digging into her soft stomach. She reached out for Halsin as he walked back to the pillows, beckoning him onto the floor with them. With each one curled around her, Yvaine felt safe, comforted, and loved, knowing that they would take care of her for as long as they would have her.
“Fangs, eh? I thought that was my job. You’ll have to show me what you can do with them later,” Astarion purred, the sound sending shivers down her spine.
“Maybe we can see who can leave more love bites on Halsin,” she sighed, before drifting off into a contented sleep.
