Kakashi grinned in self-satisfaction and left the room briefly to get Yuriko another glass of water. When he returned, he carefully removed the blindfold and as he removed the first nipple clamp, Yuriko came to with a moaning gasp, shooting into a sitting position and digging her fingers into the first things they took purchase of– the bedding and Kakashi's arm. Her pupils were dilated and unfocused, her jaw was clenched and teeth bared, and her chest heaved with heavy breaths but with each exhale came a deep, bestial growl. Seeing her like that– almost wild and animalistic– something basal awoke within Kakashi and his own pupils dilated.

"Hey…" he cooed, drawing her feral gaze to him and he saw a flash of recognition bring a bit of clarity to her and even her breathing slightly.

"Ka-ka-shi?"

He nodded with a barely restrained grin. "How are you feeling?"

"Hot… too hot…"

"Okay. Anything else?"

Yuriko closed her eyes and shook her head, confused, and a pitiful whine escaped her throat that reminded Kakashi of his ninken. He wasn't sure if the surge of emotion that he felt at the realization was of concern, arousal, or a strange and unexplainable combination of the two. It was as if his rationality and basal urges were warring with each other, and as his pupils dilated and constricted again, he realized that Yuriko's eyes had done the same before she closed them.

"Is it okay if I remove the other nipple clamp now?" he inquired, keeping his eyes on her and voice calm despite the war raging in his head.

Yuriko simply nodded, concerned for what may have come out of her mouth as she tried to rationalize what she was feeling and why. When Kakashi unclamped the other nipple clamp, the sound that escaped Yuriko's throat started as a yelp of pain that morphed into the growling panting with bared teeth as her pupils dilated again until there was only a thin ring of her violet irises visible around them, and her rationality completely abandoned her again. She lunged at Kakashi, pinning him to the ground and the corner of his lips quirked up into the quickest smirk as his warring sides came to an agreement and epiphany. In getting her to such a heightened state of arousal, he unleashed her most bestial, primal instincts and his own were now reacting to hers. While he knew that he could calm himself down enough to bring her back to herself, he didn't want to. He was curious about this newly discovered side of his beloved.

Yuriko closed her eyes and shook her head again, attempting to shake away the confusion but Kakashi's voice was deep and assertive with the undertone of a growl as he told her to look at him. When her eyes met his, she couldn't help the slight whimper of confusion and submission that she let out, intensified by Kakashi's growl and bared teeth in response to her whimper and the confident defiance in his eyes.

"Don't fight it," he demanded.

She closed her eyes and whimpered again so Kakashi's gaze hardened and he rolled them onto their sides, grabbing a fistful of Yuriko's hair at the nape of her neck and tugging hard. It was painful enough to know that he was in control and that an attempt to pull away would hurt more than she was willing to put herself through. He commanded her to look at him again and when she did and he growled to assert his dominance, Yuriko responded with a defiant growl and glare of her own.

"There she is," he grinned.

"What are you–?" Yuriko demanded through clenched teeth.

"It seems there's a part of you that isn't done playing yet, now that she's tasted a bit of freedom."

Kakashi loosened his grip on Yuriko's hair slightly but his free hand found its way to her breast and pinched her nipple hard. Yuriko yelped in pain at the sudden, sharp sensation but it slid into a growling moan and her teeth chattered with the need to take purchase of something as he rolled the sensitive nib between his thumb and finger. Yuriko thought back to Iruka's reactions to pain and finally realized what was happening to her and what Kakashi was talking about. She had reached the level that Iruka had before but Kakashi was provoking her to go further while she had calmed Iruka down.

"I can help you bring her out completely if you want," Kakashi offered, gazing into Yuriko's violet eyes that had regained the majority of her clarity back. "But you'll have to let go of everything. You'll have to trust me and allow yourself to be 100% vulnerable. Can you do that?"

He released her tortured nipple and flicked it before scratching as hard as he could down her side. Instantly, her pupils dilated again and she growled, forcing herself on top of him and baring her teeth in a threatening snarl for the pain. Kakashi tightened his grip on her hair again, pressed his stiffened length into her core and purred as he locked eyes with her, a defiant, cocky grin on his lips. His wide, heavy palm came down hard on her ass with a loud thwack and Yuriko's yelp switched to a moan when he pulled her hips down onto his, his length rubbing hard against her clit. He sat up, squeezed her ass and pulled her hair, forcing her head back to overextend and expose the full length of her neck to him. It was hard for her to breath and tears bubbled up to the corner of her eyes, but the pain juxtaposed with the heat and sensation of his sex on hers amplified both the pleasure and the pain.

Yuriko's fingers trembled as she gripped Kakashi's shoulders, pulling him closer and painfully digging her nails into his skin. He growled, raking his teeth along the length of her throat and pulling her heated core even harder onto himself. Even the thin fabric barrier of his boxer briefs was too much now. He was so hard that it was painful and he could feel how hot and wet she was for him. To draw out Yuriko's inner beast in her entirety, he'd have to embrace his own, he knew. Kakashi tackled Yuriko onto her back and returned his face to her core, pinning her down with his arm across her lower abdomen and fingertips digging into her side.

While Kakashi voraciously devoured her once again, Yuriko moaned and wailed, clawing at the floor and pulling his hair to hold him to her and he fought to release his throbbing length from its cloth prison. When he succeeded, he crawled over her and his mouth found and dominated hers as he plunged himself deep into her with one swift thrust. Yuriko's eyes bulged and back arched, her nails digging into his bicep and lower back hard enough to draw blood at the sudden, painfully pleasurable intrusion and Kakashi sighed out a moan, his entire body trembling.

"Fuck…" he growled through gritted teeth, his eyes locked on hers as his body moved of its own volition, his hips thrusting hard and fast into Yuriko's.

Yuriko panted with each thrust, her hands clawing at anything of his that she could reach– his broad back and muscular shoulders, his tight ass, his firm biceps. Her head was swimming with intense pleasure but her eyes never left his as she quickly climbed closer and closer to orgasm. Kakashi could feel her inner walls tightening around him and smirked, wrapping a hand around her throat and pressing against the artery on each side. Her eyes widened briefly but he thrust into her even harder and her eyes rolled back in their sockets.

"That's it, Yuriko. Let it go," he purred, and Yuriko's body convulsed as an intense orgasm flooded her system and she howled out in her euphoria.

Kakashi released her throat and slowed his pace, still pushing her through and extending her orgasm but when her eyes refocused on him, they were fierce and hungry and a wicked grin spread across her face. With a mischievous giggle, Yuriko locked her legs around his waist and pushed off of the floor, propelling herself forward and tackling Kakashi onto his back. Slightly dazed, Kakashi looked up at her, bewildered and it only made her grin more insidious. She braced herself on his chest and lifted herself up on her knees before coming back down on him hard and Kakashi bit his lip, suppressing a moan. When she repeated the motion, Kakashi couldn't help but huff out as their hips connected again, and he gripped onto her waist with one hand and her breast with the other, eliciting a pleased groan from her smiling lips. Yuriko bounced on his dick, feeling him deep inside of her with each downward thrust, and bit her lower lip, closing her eyes and savoring the feeling, especially as Kakashi pulled her down harder onto him.

"Ride me just like that, baby," he purred, spurring her on even more.

Kakashi angled his hips up slightly to reach even deeper into her and Yuriko's eyes widened and jaw dropped. She lost control of her body, riding him harder and faster and Kakashi's grip on her waist was bruising as he timed his upward thrusts with her downward momentum and plunged himself so deep that she could feel him press against her cervix. Their thrusting became frenzied the closer they both drew to climax and with another, deep, hard thrust, Kakashi clamped his teeth onto one of Yuriko's nipples and suckled on it as he released his seed into her, pushing her into yet another earth-shattering orgasm. She let out a high-pitched wail through clenched teeth as her fluids gushed out onto her beloved and Kakashi moaned and growled as he felt her heat wash over him.

When both of them had ridden their orgasms out, Kakashi withdrew from Yuriko's dripping sex, still hard and helped her to her feet before claiming her mouth with his, his hands aggressive against her skin as they pawed at her, the need to feel all of her insatiable. He pushed her against the wall, panting into her neck as he held her wrists above her head and rubbed his fingers along her sopping wet slit, fondling her clit and gently probing into her, feeling the slick mixture of both his and her fluids. Yuriko whimpered and panted, squirming beneath him and Kakashi's body trembled with barely restrained need.

"You have no idea how fucking crazy you make me," he growled into her ear, panting.

"Show me," she demanded in return.

Kakashi snaked his hand between her and the wall, gripping onto her rear end before lifting her up. With their eyes locked, both growling in rebellion of the other's authority, Kakashi rammed himself into her, enforcing his position as the alpha as she yelped in slightly pained surprise. Tightening his grip on the meat of her ass, Kakashi pounded her pussy mercilessly, pushing Yuriko to the brink of tears at how much it both felt amazing and painful, and right before she was about to climax, he withdrew and Yuriko howled in frustration. Kakashi chuckled mischievously, a smug grin splitting his face as he slowly slid back into her but kept his pace slow and gentle.

"Ka-ka-shi!" she snarled, glaring daggers for being denied release again.

"Yes, dearest?" he quipped. "I'm right here. No need to yell."

Yuriko growled and Kakashi slammed his hips into hers in one big, powerful thrust, pulling a yip from his defiant little beastie. When he didn't move again afterward and Yuriko whined in desperation, trying to wiggle her hips and create some friction, he gave her another bruising thrust before stopping again.

"If there's something you want, you'll have to tell me what it is," he crooned. "And why you want it."

Yuriko growled and whined again, but Kakashi remained still within her, fondling her ear with his teeth and tongue and breath to tease her into submission. When her lust became too much, she growled in frustration that he was making her beg but secretly reveled in it.

"Please, 'Kashi. I want you to fuck me."

"Oh? Go on…"

"Fuck me hard and fast and rough to satiate this insatiable, primal need. I want you to remind my mind and body and soul that we are meant to be together as you imprint the shape and size and feel of you inside of me and make me yours."

Kakashi's length twitched within Yuriko and he let out a sigh of longing and love and lust as he pressed his forehead to hers, his eyes closed and taking a moment to just feel her. She was perfect and always knew the best and right things to say, he thought, and kissed her, slowly unsheathing his length from her warmth. Yuriko moaned into the kiss and tenderly wrapped her arms around his neck, deepening it before he carried her back to the bed and threw her down onto it. Yuriko giggled as she bounced but it was quickly cut off when Kakashi flipped her onto her stomach, lifted her hips so she was on her knees and her ass was in the air and plowed into her without so much as a warning. He growled and panted into her ear, vocalizing his pleasure for her to know without him saying anything that he was thoroughly immersed and enjoying being with and inside of her. He intended to do everything in his power to grant her request and he wanted her to know it.

Yuriko's brain fogged up again at the mixed pleasure and pain as Kakashi ravaged her pussy, pounding into her without mercy. When his big, rough hand came down hard on her ass she yelped and moaned out, and when he pulled her hair, overextending her neck and limiting her breathing, her pussy got wetter, and when he panted and growled that deep, low, guttural, territorial rumble of a sound into her ear, she succumbed to his dominance being pulled deeper and deeper into the sensations and experience of being claimed and adored and coveted and loved by a true alpha personality.

Kakashi could feel her arousal and submission like a thick, sweet, dense haze in the room. It was intoxicating and addicting and all he wanted was for her to be completely and thoroughly satisfied in every way. She was aroused, but he knew she could go even further. He'd seen it happen before, so he'd prepared specific toys and trinkets with her in mind to help her achieve that heightened level. Pausing briefly in his pelvic onslaught, he lifted Yuriko so her back was pressed to his chest and distracted her with a deep kiss. While still swaddled inside of her he placed the nipple clamps back onto her breasts while rubbing her clit and when the clamps were securely in place, he bent her back over, smacked her ass, and pulled her hair, thrusting his hips into hers with fervor. Her breasts swayed, bouncing and jostling the clamps each time their hips met, juxtaposing the pleasure and pain even closer.

With his big, hot, thick cock ramming deep inside her, the pain of the clamps and her hair pulled, the limited air, the random spankings, and the sounds of both her own and her beloved's moaning, groaning, panting, and growling, Yuriko's senses were overwhelmed and orchestrated the perfect euphoric symphony. Her orgasms came fast and strong— he'd counted five since returning to the bed, three of which occurred after the nipple clamps— but Kakashi was far from finished. He wasn't satisfied that she was satisfied enough. She called "yellow" just earlier from cumming so much by the skill of his tongue and fingers alone, and he recalled telling her that he intended to please her to the point that she'd be begging him to stop before the night was over. Being a man of integrity, he had to uphold his promise.

Kakashi slowed his pace and slowly withdrew himself from her twitching inner walls and allowing Yuriko a brief moment to catch her breath. Her legs shook and she struggled and fought to regain her senses, but Kakashi didn't give her the time to regain them fully. Instead, he firmly grabbed hold of her ass, a cheek in each hand, and licked from her clit to the puckered ring of her rear end. Yuriko gasped and hummed in approval, relaxing her muscles to allow easier access for her beloved. Preparing her even more for what he had in mind next, Kakashi smacked her ass and resheathed his full length into her aching pussy, pressing his thumb to her tight little asshole and slowly inserting it at the same time. Yuriko moaned out, her eyes crossing slightly and a loopy grin splitting her face.

Reaching again for the bedside table, Kakashi grabbed a bottle of lubricant and a silicone anal plug with five teardrop shapes that got slightly bigger in size as they got closer to the handle that had a cute heart-shaped purple jewel on it. He applied a liberal amount of the lube onto the plug and slowly pushed the toy into her. As each teardrop was inserted, he could feel Yuriko's inner walls tightening around him and when the whole toy was inserted, her entire body was trembling and she was panting, kneading the bedsheets like a kitten suckling at its mother's teet, and purring with her teeth bared and chattering again. Seeing her pleasure, Kakashi smiled and ran his hand up her spine before scritching the back of her neck at her hairline. Her smile broadened, body buzzed with energy and purring intensified and Kakashi's smile softened and grew, full of love, adoration, and pride.

"You're such a good girl, Yuriko. You've embraced your inner beastie so well. I'm so, so proud of you," he cooed as he gazed down at his beloved in her euphoric, non-verbal state, and Yuriko whined in joy, turning her head as much as she could to feel his caress on her cheek. "Good girls deserve a treat, don't they?"

Yuriko nodded in agreement and wiggled her rear end, moaning as the movement applied pressure to just the right places in both her ass and pussy. Kakashi's tender smile broadened and he took the hint, slowly pulling out until just the tip was still inside her, and plunged back in, jostling the nipple clamps and plug and eliciting a whimper and exhale from Yuriko as his hips met hers, forcing the air out of her. He continued to thrust into her, gradually gaining speed and power and as they slowly climbed to climax, they maintained eye contact, intensifying their spiritual connection. They were both so close to orgasm, but this one had to be the biggest one yet, Kakashi thought. She'd come so far in her primal journey that she more than deserved another cosmically powerful orgasm as a reward and to imprint a lasting memory in her mind.

Kakashi reached to the bedside table for the final piece to his master plan— a vibrator— turned it on to the highest setting, and placed it directly on her clit while he continued to pump into her. Yuriko's eyes widened, eyebrows raised and furrowed and jaw dropped. In an instant, the most powerful orgasm she'd ever experienced in her life overtook her and she screamed into the bed, her fists clenching onto the bedsheets so hard that her knuckles turned bone-white. Her vaginal walls convulsed around Kakashi, pulling him over the edge to his own cosmic orgasm, spraying a thick, creamy load deep into her womb and it seemed to last ages for each of them until they both blacked out and collapsed.

Kakashi was the first to come back into consciousness and took a moment to breathe and regather himself. When he sat up, he gazed down at his beloved, and seeing her blissful smile and peaceful breathing despite how completely disheveled her hair was, Kakashi became awash with compersion and smiled, himself. He tenderly caressed her arm and smoothed her hair away from her face. Yuriko's eyes fluttered open and she purred and sighed in contentment as her smile broadened.

"Hey there, beautiful. Welcome back," Kakashi chuckled. "How are you feeling?"

"Thoroughly satisfied… and a little sore," she chuckled back.

"Then I have succeeded in my mission. Are you ready or able to help clean up?"

Yuriko took a brief moment to assess her body and nodded, "I think so."

They cleaned up slowly, and when everything was put away in its proper place, the couple took a bath together, Yuriko seated comfortably between Kakashi's legs and laying back on his chest. The steaming water loosened her muscles up even more and soothed the newly forming bruises scattered over her tender skin from their intense lovemaking, and stung at the claw marks crisscrossing Kakashi's back, bum, shoulders, and arms. After their intimate bath, the sweetness continued in bed as they lay down to sleep, swaddled together in warmth, comfort, and loving bliss.
