Sans left the bathroom after he took a good long look at himself. This new form would be beneficial for his plans, and he had to admit, he quite liked this new body. The pieces were falling into place quite nicely.

He strolled into the kitchen to find Frisk busy washing the dishes they had left behind. She didn't seem to notice him as she just kept on scrubbing, a pensive expression on her face as she scrubbed an already sparkling dish. Walking up behind her, he wrapped fleshy arms around her middle and nuzzled his face into the crook of her neck, softly humming at the strange sensation.

"You know, It's still a little weird getting to feel skin on skin." He murmured absently, his lips brushing against the sensitive flesh of her throat.

Setting the dish aside, she reached up to hold the arms around her waist while she giggled and squirmed at the ticklish feeling on her neck. He chuckled lowly at her reaction and peppered gentle kisses to her skin, marveling at the little gasp she couldn't contain.

Frisk sighed softly at the pleasant feeling of his lips on her skin, but her mind buzzed frantic with worry. What if the council found out that monsters could 'turn human'? Would they immediately be seen as a threat, would more protestors rise up and demand for their persecution? How would their actions affect not only their future, but those of all the monsters?

She swallowed the lump in her throat and tried to chase away the doubt. If anyone could save their people, it was Sans, she mused.

She would have to keep this under tight wraps though, for if the council found out about the experiment, it could very well end in the extinction of all monsters.

She instinctively stiffened, catching the attention of her now human lover. He whispered softly against her skin and ran his hands up her arms slowly, reassuringly, easing the tension from her body.

Smooth lips curved upward as he ran his tongue up the thin chord of muscle to her ear, sucking the unsuspecting appendage in his mouth and humming lowly.

He smiled at the shiver she fought to hide, and decided that just wouldn't do. Releasing it with a harsh nibble, he blew softly against the shell of her ear and reveled in the tightening of her arms on his, small pants escaping past parted lips at his pleasurable torture.

Truth be told, this was a new experience for the both of them, one that he had every intention of exploring. Fast, slow, however she wanted for as long as she wanted.

Rumbling low in her ear, he whispered huskily, "What do you say we hit the hay? Or more importantly roll in it."

She giggled softly at his joke, her own voice airy and high as she fought of the instinctive blush, "Let me finish these first, love. Then we can play all you want."

A grin spread across his lips as he slowly tightened his grip and placed tender kisses and nips along her throat in an attempt to entice her. His hands continued their lazy movements on her arms before moving up to gently comb her hair to the side while his mouth never stopped licking, sucking, and nibbling on the sensitive flesh. Each moan and sigh that met his ears only fueled his ever growing desire, and with a barely restrained growl, he pulled her waist to his to show her just how she affected him.

This felt different than it ever had before, and he couldn't care less as long as his belovéd didn't stop writhing at his ministrations, as long as she never stopped whispering his name like a life-line.

She felt her resolve growing weaker with every passing moment of his sensual torture, until finally she couldn't take it any longer. Turning in his arms, dishes long forgotten, she cupped his face in her hands to guide him into a searing kiss that steadily grew more needy and longing with every brush of lips. Sans, not one to back down from a challenge, grasped her hips and lifted her onto the countertop, pressing his weight into her middle as he took what he wanted, exploring her mouth feverishly, like a man starved.

The two pulled away, both of them panting for breath, but Sans wasted no time in unbuttoning her shirt and sliding it down her arms hurriedly, his gaze drinking in the sight of black lace hungrily. She blushed heavily, but allowed the garment to fall to the floor while she went to work pulling his white t-shirt over his head, throwing it to the corner of the room before she raked her fingers across his chest, marveling at the hard muscles that flexed under her touch. Sans groaned at the feeling of her fingers grazing his skin. She was everywhere, exploring the planes of his bad, running hands over his biceps, clinging to his shoulder. His breathing labored, he ceased her exploration as she surged forward, prying her way under the band of his sweats to palm him gently.

Smiling wickedly, she set to work pumping him slowly, basking in the low groans and grunts he couldn't fight off. His body was taut, muscles locked as he shuddered above her, the sensation all-encompassing and overwhelming.

He groaned weakly into her ear and braced his arms on the countertop as she tightened her grip, moving faster now, emboldened by his lack of control.

He stopped her hand firmly, and she flinched back, fearing that she had somehow upset him, but when he looked back into her eyes, she noticed the hunger in his gaze, the wicked smirk he gave her just before snatching her bra down to expose her soft mound to the air.

She blushed profusely and tried to cover herself, but deft hands shot out, pining one against the counter and the other against his chest as he dove in, intent on giving the little vixen as much as she gave. Limber tongue darted out to lap at her pebbles flesh, relishing in her sweet moans and panting breaths. Chuckling darkly, he made sure to caress her slowly, a sharp contrast to the frenzied pace they had indulged in moments ago.

No inch of her left unmarked, taking his time to kiss and nibble, suck on her willing flesh until there was nothing but marks, an unconscious instinct on his part to claim his woman. Judging by the way she writhed in his arms, it seemed she had no objections. Chuckling softly, he released one arm and palmed the other breast while he clamped gentle teeth to her perky bud, making her back arch and her hips seek his unconsciously.

He smiled against her breast as her hand pressed his skull tightly against her flesh, and without hesitation he answered her request, sucking hungrily and flicking his tongue against her bud as he did so, never stilling in his ministrations on her other breast. After all, who was he to deny this beautiful woman anything she desired?

Switching to the other bud, he dipped his hand low, caressing the flat of her stomach in his path to her shorts, carrying on past the band and pressing against her most intimate place with rough pads, matching his frantic mouth. With quick strokes, he caressed her bundle roughly, breaking from her breast to kiss her hurriedly as she panted and arched into his chest.

He kissed her once more and quickly grabbed her by her hips, picking her up effortlessly. She squeaked in surprise, although she cared little as he teleported them to the bed and tipped over, pinning her to the mattress. A desperate plea flew from her lips as he ground harshly against her sex, and had she had the ability to think past the lustful haze, she might have even been embarrassed by the urgency in her voice. Sans definitely heard, however, and smiled softly against her skin before moving his hand down her sides reverently, forcing himself to take things slowly for their first time as two physical humans.

He only responded when she bucked her hips against him, sending little jolts of pleasure up his spine as she moved relentlessly beneath him, her head whipping forward to catch his lips in a heady kiss that banished all thought from their minds, their bodies and emotions in full control. He responded to her sense of urgency, a low growl leaving him as he dominated their kiss while two hands yanked her hips closer to his own, pressing her into his arousal and setting a slow, drawn out pace that served to work her up and simultaneously draw out her pleasure.

When he was certain they could wait no longer, he picked her up by her hips and slid her shorts and panties down her legs, brushing sensually along her thighs as he did so, although Frisk didn't seem to notice as she rocked against him with reckless abandon. Large lavender eyes met molten gold as he climbed over her body, drinking in the little red marks over her breasts and neck, the fullness of her lips, swollen from their kisses, and her slightly mussed hair. She was more beautiful than he could ever remember, and with herculean effort, he forced himself to remain still as she pushed him up and drank in the sight of his naked flesh.

He had already rid himself of his shorts and she couldn't help but stare at him in awed fascination, her hands moving to trace chiseled abs, and hard muscle beneath them. Her face darkened with a rosy blush as she took a good look at his manhood, and with a shy glance up at him, she reached out to grasp him in her hand, relishing the low groan that passed his lips and the way his eyes seemed to darken under her attentions. A small squeak left her as he intentionally flexed beneath her touch, and before she knew it his lips crashed down onto hers, his form pushing her back against the bed once more.

"Enough teasing, love. You'll have your chance to explore later, but right now you're all mine."

His body was on fire, the pleasure of her touch igniting the flames of desire from a small flame to a raging inferno. His face was hot, his skin feverish, and the only thing that could save him now was the cool flesh beneath his palms, the loving passion in amethyst eyes, and the unwavering acceptance of the woman beneath him.

They wasted no time in joining, their foreplay having been drawn out long enough. They made love as if it were their first time. Going slow and gentle, both experiencing new sensations and taking the time to worship one another's bodies until they inevitably crashed through that peak together.

After they had both calmed from their climaxes, Sans propped himself up on one elbow and lightly ran his other hand across the plane of her stomach. She giggled softly at the ticklish feeling and playfully swatted his hand away, only to have it return the next moment.

He smiled and took in the beautiful woman lying next to him, her skin damp with sweat, her eyes closed in bliss and the soft smile she reserved only for him playing on her lips. This girl, sweet little Frisk was his in mind and body, and he realized he could wait no longer.

Taking in a deep, settling breath, he cupped her cheek and kissed her temple, coaxing her to open her eyes as he pulled back. She complied readily, reaching out to brush tender fingers against the curve of his cheek, that oh so brilliant smile still on her kissed bruised lips. Nothing would ever be more lovely to him than the picture that she was now. So, with a pounding heart and flushed skin, he breathed out the words he could no longer hold back.

"Frisk, would you.. would you want to marry me? I want to spend my life by your side, making you smile, laugh, and loving you the way you deserve. Be my wife?"

She looked up at him in shock, after all this wasn't exactly the way she pictured a proposal going, both of them sweaty and naked tangled in the sheets.. but she couldn't have been more happy at the thought of marrying the monster she loved with all of her heart.

She smiled despite the tears running down her cheeks, "Why don't you ask me as you really are? Your human form is nice, but after all, I did fall in love with my bonehead."

He chuckled and slid the bracelet off his arm, covering her eyes while he kissed her tenderly, only stopping when he knew his transformation was over. Pulling back, he nuzzled his skull against her forehead and gazed deeply into her eyes.

"Knock, knock."

She groaned, "who's there?"

He smiled, "Marry."

"Marry who?"

"Marry me," he finished laughing, but his eyes held the same warmth and adoration as before.

She slapped his arm playfully until he finally relented, "Please, do me the honor of becoming my wife?"

She smiled and kissed him sweetly, "Of course I will."

He smiled back and ran a bony hand over her cheek, "I'll definitely have to talk with Asgore and the Queen formally for your hand, but I don't think I can wait. Frisk I want you to be mine now."

She agreed and rested her hand against his bony one, "I know, love. I wish we didn't have to wait."

At his ear splitting grin she looked up at him quizzically until he calmly explained that they could marry each other right here and now.

"I'd need to pull our souls out to the surface, but it's not painful. The way of monster marriage is all about the merging of souls, since monsters only exist through their souls, it is permanent and bonding," he hesitated before whispering, "This won't be like a human marriage, Frisk. This will last until the end of our shared existence. There is no divorce."

Reaching out to grasp his skeletal cheek, she smiled up at him warmly, "I wouldn't have it any other way. I don't have any intentions of leaving you Sans. I want you. Always."

He brought her into a tender embrace, just letting one another feel the love and adoration pass between them. When he finally pulled back he looked into her eyes searching for any hesitation, and when he found none he scooted back on the bed, leaving a small bit of room between the two.

"Are you ready?"

She nodded and watched as he held out his hand in front of his chest and brought forth his soul. It was quite large, the only thing she found odd was the fact that it was upside down and the blue light coming from it was slightly dimmed with a few cracks running through it. She noticed him stiffen and she reached out to cup his soul in her palms before kissing it softly. He gasped and shivered, his face flushed in a bright blue blush.

"F-Frisk, d-don't do that. At least not yet.." he replied with barely controlled composure.

She blushed at his reaction and nodded before letting his soul relax back at his side. Soon she felt her soul being gently pulled from her body to rest in the palm of her hand. It was still a brilliant red, but it seemed a little more dull, but since she had recently had a determination extraction she didn't think much of it, especially when Sans explained that it would take a few days before her soul would regenerate the lost level of DT.

She looked a bit nervous but nodded before asking him what the next step was. He gently cupped his soul and brought his halfway to reach hers and waited for her to do the same. When she brought hers forward he let his soul gingerly float around hers in a slow orbit, his eyes never leaving the dancing soul as it wrapped around hers with a tenderness that matched his love for her. She, however, watched seemingly mesmerized at the way it danced around her own in a slow display of hesitant adoration.

She smiled and felt the love she held for her monster soar to new heights. Just as she was focusing on her affections, she watched as her heart seemed to glow in a brilliant red light while joining his soul in its sweet dance that progressively swirled faster before them. The two souls floated above their outstretched palms, encircling one another as blue met red casting a beautiful purple glow amongst them as the souls rose higher and higher above them. Soon, the light grew far too intense, and Frisk had to look away from the blinding light, but Sans continued to watch, not fazed by the illumination in the slightest.

After another few moments she felt a chilling sensation coarse through her body, almost as of she was playing happily in the winter snow. It was peaceful and soothing. She glanced at Sans noticing how he was sweating lightly.

He smiled at her reassuringly as she looked at him in concern, but as she went to move he shook his head and held her still with his gaze. At the same time Frisk had experienced a cold sensation, he felt an overwhelming warmth envelop his bones, almost as if he were encased in a gentle summers heat. He couldn't help but be amazed at the soul binding that took place in front of their very eyes. Her soul was like a warm beacon of hope, filling him with an all consuming peace. He never wanted to forget the feeling.

They both knew the merging was over when the two souls glided down into their respective palms, hers glowing brightly with a softly swirling blue encased inside. His was glowing brighter than before, and a few of the cracks looked to be healed. He looked at her in amazement, noting how her soul had swirled with his power. Looking down at his own, he noticed a brilliant red swirl within his own soul. Tears leaked from his eye sockets at the sight before him. He brought his soul back into his body and gently guided hers back into her body before embracing her tenderly.

They both were irrevocably bonded. And they wouldn't have it any other way.
