Day 5: Alpha/Omega

Day 5: Alpha/Omega

"Anna, you need to stay away," Elsa's voice was strained, laced with barely restrained tension as she stood at the door to her bedroom, her knuckles white from gripping the doorframe. She could feel it—her rut approaching fast, the familiar burn starting to coil deep inside her, a warning sign of what was to come.

But Anna, as always, didn't listen.

"I'm not leaving you alone," Anna said, her voice firm with determination. She stood in the hallway, just a few steps away from Elsa's door, her eyes filled with concern. "You shouldn't be by yourself, Elsa. Not when... not when you're like this."

Elsa's heart raced, her pulse pounding in her ears as the scent of Anna's presence filled the air. It was sweet, intoxicating, and it hit Elsa harder than it should have, her Alpha instincts roaring to life the moment Anna came too close. She took a shaky breath, trying to keep control, but it was impossible with Anna standing so close, with her Omega scent filling the air like a promise Elsa couldn't ignore.

"You don't understand," Elsa growled, her voice lower now, a warning edge creeping into her tone. "You have to stay away. I can't... I can't control myself when I'm like this."

But Anna, stubborn as ever, didn't back down. "I'm not afraid of you," she said softly, her eyes locked on Elsa's. "I've never been afraid of you."

Elsa's breath hitched, her body trembling with the effort of holding back the surge of heat building inside her. Anna's scent was too strong, too tempting, and it was making her head spin, making her instincts scream at her to claim, to take, to make Anna hers.

"Anna, please," Elsa whispered, her voice breaking as she took a step back, trying to distance herself from the overwhelming pull of her Omega sister. "I'm not myself right now. If you come any closer... I won't be able to stop."

Anna's eyes softened, but there was still that stubborn determination in her gaze. "I know you, Elsa," she said gently, taking a step closer despite Elsa's warnings. "You'd never hurt me. And I'm not leaving you to go through this alone."

Elsa's whole body tensed as Anna stepped closer, the air between them thick with the heady scent of Anna's Omega pheromones. It was too much. Too close. Too tempting. Elsa's grip on the doorframe tightened, her nails digging into the wood as she fought the overwhelming urge to pull Anna inside and lock the door behind her.

"You don't know what you're saying," Elsa growled, her voice trembling with the effort of holding herself back. "You don't understand what happens when I go into rut."

Anna took another step closer, her scent wrapping around Elsa like a blanket, warm and inviting. "Then show me," she whispered, her voice soft but filled with a quiet resolve. "If it's too much... if you need to claim me, then do it."

Elsa's eyes widened, her breath catching in her throat as Anna's words hit her like a punch to the gut. Claim her? Anna was offering herself willingly, knowing exactly what that meant—what that would do to both of them. She wasn't just defying Elsa's warnings; she was offering herself, her Omega instincts driving her to be close to her Alpha sister in a way that was both dangerous and irresistible.

"Anna, I can't—" Elsa started, but her words were cut off by the sound of the door closing behind her as Anna stepped into the room, sealing them inside together.

The click of the door echoed in the quiet room, and Elsa's whole body went rigid, the full force of Anna's scent crashing into her like a tidal wave. She could feel her control slipping, her Alpha instincts taking over as the heat surged through her, making her vision blur with need.

Anna's eyes met Elsa's, and there was no fear in them, only understanding. "You don't have to hold back," Anna whispered, her voice soft but steady. "I'm here. I'm yours."

Elsa's breath hitched, her heart pounding in her chest as the words sank in. I'm yours. The declaration sent a jolt of pure need through her, making her whole body tremble with the force of it. Anna was offering herself completely, and the part of Elsa that had been fighting for control—fighting to keep her distance—crumbled in the face of that truth.

"I can't stop," Elsa whispered, her voice rough with the effort of holding back. "If I start... I won't be able to stop."

Anna stepped closer, her scent filling the space between them, and gently reached out to cup Elsa's cheek. Her touch was soft, grounding, but the heat between them was undeniable, and Elsa could feel her body reacting instinctively to the closeness, her Alpha nature roaring to life.

"Then don't stop," Anna whispered, her voice full of trust, full of love. "I want you, Elsa."

Elsa's resolve shattered.

In an instant, she was on Anna, her hands gripping her sister's waist as she pulled her closer, their bodies crashing together with a force that made Anna gasp. Elsa's mouth was on hers before Anna could say another word, their lips colliding in a rough, desperate kiss that was fueled by months of pent-up desire.

Anna whimpered into the kiss, her hands sliding up to tangle in Elsa's hair, pulling her even closer as she melted into her sister's embrace. The heat between them was unbearable, the tension that had been building for so long finally snapping as Elsa claimed Anna's mouth with a hunger that bordered on feral.

Elsa's hands moved quickly, sliding down to Anna's hips and pulling her tight against her, grinding their bodies together as the heat coursed through her veins. She could feel the fire inside her growing stronger, her body aching with the need to claim, to mark, to make Anna hers in every possible way.

Anna gasped, her back arching as Elsa's lips trailed down to her neck, her teeth grazing the sensitive skin just below her ear. The scent of Anna's arousal filled the air, mixing with the heady scent of her Omega pheromones, and Elsa's vision blurred with need. She could feel herself losing control, her Alpha instincts taking over as her hands moved with a mind of their own, pulling at Anna's clothes, desperate to feel her skin against hers.

"Elsa," Anna whimpered, her voice breathless as she clung to her sister, her body trembling with anticipation. "Please..."

Elsa growled softly, the sound low and primal as she pulled Anna's dress down, exposing her bare shoulders and the soft curve of her breasts. The sight of Anna—her skin flushed with arousal, her lips parted in a breathless moan—made something snap inside Elsa, and before she could stop herself, she was pushing Anna back onto the bed, pinning her beneath her with a possessive growl.

Anna's breath came in short, ragged bursts as Elsa hovered over her, her eyes dark with lust. There was no going back now. Anna could see it in Elsa's eyes—the rut, the need, the undeniable pull of their bond. She was at Elsa's mercy now, completely at her Alpha's mercy, and the thought sent a shiver of excitement down her spine.

"Anna," Elsa growled, her voice low and rough as her hands slid down Anna's sides, tracing the curve of her waist before gripping her hips firmly. "I need you."

Anna's heart raced, her body trembling with anticipation as Elsa's hands moved lower, pushing up her skirts and exposing her completely to her Alpha's gaze. Elsa's fingers trailed over the soft skin of her thighs, teasing but never quite giving her what she needed.

"I'm yours," Anna whispered, her voice shaky but filled with conviction. "I've always been yours."

Elsa's eyes darkened, her breath coming in short, ragged bursts as the words hit her like a physical force. Without another word, she lowered her head, her mouth trailing hot, open-mouthed kisses down Anna's chest, her teeth grazing lightly against the sensitive skin of her breasts. The sound of Anna's breathless moan filled the room, and Elsa growled softly, her Alpha instincts roaring to life.

Anna's hands tangled in Elsa's hair, pulling her closer, her body arching into the touch. She needed Elsa—needed her touch, her mark, her claim. And Elsa, in the throes of her rut, was more than willing to give it to her.

With a low growl, Elsa's hands gripped Anna's thighs, pulling them apart and settling herself between her sister's legs. The scent of Anna's arousal filled the air, heady and intoxicating, and Elsa's whole body trembled with the force of her need. She could feel the slick heat between Anna's legs, the wetness that signaled her Omega's desire, and it took every ounce of restraint Elsa had not to lose control completely.

"Elsa," Anna whimpered, her voice breathless as she shifted beneath her Alpha, her hips pressing forward in a silent plea for more. "Please..."

That soft plea was all it took to shatter Elsa's last thread of control.

With a low, primal growl, Elsa's eyes darkened, and the tension in the air became unbearable. Her rut surged through her, clouding her mind with nothing but the need to claim, to possess, to make Anna hers in every possible way. Her breath came in short, ragged bursts as she pulled back for a moment, lifting her own dress up over her hips to free herself.

The sight of Elsa's Alpha cock, hard and throbbing, made Anna's breath hitch. She had never seen it before, but the size and the heat radiating from Elsa made her entire body ache with need. The slick between her legs only increased, her Omega instincts pushing her to be claimed, to be filled, to be taken completely by the Alpha who was everything to her.

Anna's eyes widened as Elsa positioned herself between her legs, her hands gripping Anna's hips tightly, her touch possessive and commanding. There was no hesitation in Elsa's movements now—only raw, unfiltered need as she lined herself up with Anna's entrance, the tip of her cock brushing against the slick wetness of her sister's core.

"Anna," Elsa growled, her voice low and rough as she leaned down, her forehead resting against Anna's. "I can't stop. I need... I need to take you."

Anna whimpered softly, her breath coming in short, desperate gasps as she nodded, her body trembling with anticipation. "Do it," she whispered, her voice shaky but filled with need. "I'm ready. I want you."

That was all Elsa needed.

With a sharp, desperate thrust, Elsa entered Anna in one smooth motion, her cock pushing deep inside her sister's tight, slick heat. Anna cried out, her hands gripping the bedsheets as her body jolted at the sudden intrusion, her hips arching off the bed as Elsa filled her completely. The stretch was overwhelming, the burn intense as Elsa's thick cock forced its way inside, but Anna's body responded immediately, her Omega instincts taking over as she clenched around her Alpha, welcoming her in.

Elsa growled low in her throat, her hands tightening on Anna's hips as she thrust deeper, her cock pushing as far as it could go. There was no holding back, no slowing down. Her rut had taken over completely, and her body moved on pure instinct, driven by the need to claim Anna, to make her submit fully to her Alpha.

Anna's breath came in short, ragged bursts as Elsa began to move, each thrust deep and rough, forcing her hips back into the mattress with the sheer force of it. She whimpered, her body trembling with the intensity of the sensation as Elsa filled her again and again, her slick heat clenching around her Alpha's cock as her body responded to every thrust.

"Elsa," Anna gasped, her voice breaking as the pleasure overwhelmed her, her body shaking with each deep, relentless thrust. "It's... it's too much..."

But Elsa wasn't slowing down. The rut was too strong, the need too overwhelming. Her hips moved faster, her cock plunging deep inside Anna with every thrust, her body trembling with the effort to push deeper, to claim more of her sister. She could feel the tightness of Anna's virgin walls squeezing around her, the slick heat of her Omega's body driving her wild with need.

"You're mine," Elsa growled, her voice rough and possessive as she leaned down, her lips brushing against Anna's ear. "You'll always be mine."

Anna whimpered, her body shaking uncontrollably as Elsa's words sent a shockwave of pleasure through her. The sheer intensity of the claim, the way Elsa's cock filled her so completely, made Anna's whole body ache with need. She could feel the knot forming at the base of Elsa's cock, the swelling pressure pushing against her walls, and it only heightened her desire.

"I... I can't," Anna gasped, her voice trembling as her body neared the edge. "Elsa... I can't."

"You can," Elsa growled, her hips slamming against Anna's as she thrust harder, her cock swelling even more inside her. "You can take my knot."

Elsa growled, the feeling of Anna's tight, quivering body around her pushing her to the edge. Her knot swelled fully, locking them together as she buried herself deep inside Anna, her cock throbbing as her own orgasm finally hit. With a low, guttural moan, Elsa came hard, filling Anna with her seed as the knot locked them in place.

With a cry, Anna's body convulsed, her orgasm ripping through her with a force that left her breathless. She clenched tightly around Elsa's cock, her walls milking her Alpha as she came hard, her hips bucking wildly beneath her sister's relentless thrusts.

The intensity of the moment left them both trembling, their bodies shaking with the force of their release. Elsa's breath came in short, ragged bursts as she held Anna close, her cock still pulsing inside her sister as the knot held them together, sealing their bond in a way that was both primal and intimate.

For a moment, the room was silent, save for the sound of their labored breathing. The heat between them had finally broken, replaced by a deep, overwhelming sense of satisfaction, of completion. Anna's body was still trembling, her hands clutching at Elsa's shoulders as she tried to steady herself, her breath coming in soft, uneven gasps.

"Elsa," Anna whispered, her voice soft and filled with emotion. "That was..."

Elsa smiled softly, her forehead resting against Anna's as she whispered back, "I know."

They stayed like that for a while, their bodies locked together by Elsa's knot, the aftershocks of their release still pulsing through them. The rut had passed, leaving them both feeling raw, exposed, but deeply connected in a way that went beyond the physical.

Elsa's hands slid up to cup Anna's face, her touch gentle as she looked into her sister's eyes. "Are you okay?" Elsa asked softly, her voice full of concern now that the intensity of the moment had passed.

Anna smiled, her eyes filled with warmth and love as she nodded. "I'm more than okay," she whispered, her voice soft but full of affection. "I'm yours."
