"Your worst fucking nightmare."

The sound of the punch alone made my entire day worth while. Like glass shattering or maybe his jaw being dislocated. It felt so satisfying. Even flung his body back into the wall behind us. A splat of crimson painted one of the white walls. It caused the binds around me to slacken as a large puddle of black pooled on the floor where the other Human had once stood.

Was it wrong of me to hope she had ended up killing my supposed father with that one blow?

Probably but strangely enough I found myself unable to care. My arms were at least free now. So even if I was still being held around my rib-cage helping Frisk wasn't out of the question. Though in all reality being put back on the ground would have been best for me. Because that other Human was getting up. And there wasn't a hell of a lot I could do to move out of the way.

Maybe this would've been less problematic if I had more than one HP. But well there wasn't much I could do about that right now was there?

Well I guess watching the show wasn't a bad idea. See once that little freak got on his feet he was after Frisk. Bastard still favored a knife it seemed. Not that is scared Frisk. I saw her soul start to glow even brighter before. Her determination had started to pick up.

No way he was going to win now.

His first strike was aimed at her chest. With a simple move not only did she lean back but bring a knee up to his stomach. His other hand attempted to reach out and grab her. That purple armor seemed to prevent it which was good. Other wise he'd had her right arm in his grasp. Her counter attack was to lower herself then sweep his legs out from under him with impressive speeds.

As he fell she followed through and used her hands as a center point to put all her weight. In doing so she was able to swing out her other leg and smash it into him. And even better the little bastard now had no knife in his hands. Frisk didn't even give him the chance to get it back. With rapid footwork she stepped closer to him and came down with a stomp which he rolled away from. It let her use her other foot to slide the knife all the way back to where my brother and Andy stood.

Enraged at the loss of his toy and how easily he was getting his butt kicked he summoned up fire in his hands. At the ready Frisk back flipped away from him several times. Didn't stop those flaming orbs being shot at her. But it did make it harder to even touch her. And the ones that did only took chunks out of her armor. Now with some space between she quickly caught onto the fact her armor was not going to withstand his magic.

Guy almost looked thrilled to know that her armor wouldn't be standing up to his attacks. A flicker of curiosity crossed Frisk's face. Once more she was quickly finding herself under attack. No knife in hands he resorted to some old fashion hand to hand combat. Kept his hands covered in flames. Seems he really wanted that armor of hers gone.

It was like trying to punch water. Her moves were so fluid and precise. Lifting a knee to block the blow of a fist. Her forearm deflecting a kick. Add a crouched spin into the mix and now she was behind him. Took a hard kidney punch for that.

His elbow attempted to hit her throat. But landed on her chest instead thanks to quick maneuvering. Staggered but not done yet she jumped up as he came rounding on her with a punch from above. Her hands grabbed his shoulders using them to flip off from only to land several feet behind him. Now on her feet frisk looked at her armor once more. I knew that look, she had a hair brained idea cooking in her head.

Again he stood some distance from her thinking perhaps it would help him. Wrong. She yanked off her right boot and managed to hurl it at him. Made a dull thump sound then fell to the floor. An awkward silence over came up all after this. Just what in the hell had she hoped to achieve with that?

For the smallest of moments Frisk looked at him blankly. Then a wide grin split her face stretchering from ear to ear. Oh god this was going to be good. And I had front row seats. Shaking it off as nothing more than a stupid fluke the cocky little shit motioned for her to bring it on. She gave her nod then flung herself at him.

Those ruby eyes widened in terror realizing that had been a mistake. All her power was in speed after all. Those legs of hers were powerful deadly weapons from all those years of dodging monster attacks. And looked damn good in those pants right now. That was for another time however. Because Frisk literally shot past him only to turn and spear him from behind.

Granted he didn't fall over but that seemed to work just fine for her. With both arms locked around his torso and his balance shaken she grabbed him with tendrils and flung him right over her with all the might she could muster. Didn't have nearly enough time to catch himself before that wall kissed his back. My attention was on Frisk when she cringed in pain. Seems he'd managed a lucky blow on her in all the fuss. Dick had managed to catch her shoulder with some fire.

I could only hope it wasn't too bad. Though from here her shoulder looked red and raw as hell. Finally he was on his feet. And Frisk removed the helm she had. Her last bit of armor. Her foe smirked uncaring as to the fact she was now holding it. However I'm sure his mind changed the instant it hit his face with whatever force she had kicked it at him with.

Undyne burst out laughing along with my brother shattering the momentary silence which followed. Both agreed that the look upon his face had been priceless. Hell even I couldn't stop myself from cracking up. God that had just been too perfect. Not to mention the little victorious fist pump she gave after landing it. Leave it the punk to be a kill joy however.

"Figures you would resort to such childish tricks. Little bleeding heart." He growled wiping the blood from his nose.

"Childish tricks? Hardly. This is how adults do battle."

"And what would you know of the art of war little bleeding heart?"

"Sans? Papyrus?"

"Yo?" I quirked a brow.

"NYEH?"

"Blue." She answered her eyes never looking away from the other Human.

"You heard her bro! Let's show this nerd what it means to be blue!"

"BLUE IT IS BROTHER!"

My hand reached out and turned his soul a deep blue. He looked baffled at the concept. Which made it nice and easy to fling him into my brother's on coming attack. Blue and white bones alike clobbered him in an endless string of pain. Only when he smashed into another wall did I let him go. And boy was he pissed.

Oh big surprise he starting coming at me. Had fire in his eyes too. Like he just could not wait to kill me again. Sadly he was going to have to wait.

"Hope you don't mind me CUTTING in!" Frisk blurted as she delivered an uppercut to his jaw.

"Please by all means." I laughed.

"Again with these damn puns?"

"What can I say? I fell in love with a punny guy." She winked at me.

"Awh Frisk don't you know that you'll always be my..."

"SANS DON'T YOU DARE!" My brother commanded in an irate voice.

"...Vertae-bae!" I shot back with a grin.

"OH MY GOD. REALLY?" Papyrus asked angrily.

"Sorry Paps, but you know I just can't resist a good pun." I chuckled.

"Let's see whose laughing when your dead!"

Oh shit I'd forgotten he could jump. And I was still a bit uh, tied up at the moment. Wasn't this exactly what I had been worried about a little bit ago? Karma I hate you.

"Undyne!" Frisk sounded panicked.

My eyes closed tightly but thank god the blow never came. Rather when I did open them I saw the murder about ten inches in front of me. Unable to move because his soul was now green. Thank god Frisk had brought Undyne with. Or I suppose I could have used my magic. Sort of hard when you're panicked though.

So thank god for angry fish captain of the royal guard to save me.

"As long as your soul is green you can't escape. How's that for not knowing war you little brat?"

Frisk yanked on the large black appendage which had me suspended in the air. Much to my surprise it simply fell over. Which normally would have been fine. But seeing as I currently being held by it well that made this an issue. Up until Frisk caught me that was. I heard her relieved sigh too.

Guess we were both worried I might end up without a soft landing.

Undyne was currently giving this guy hell it seemed. Spears just kept flying at him. And boy, he really sucked at dodging. At least five hit him at once. Not only that but my brother was adding his attacks into the mix here and there. Guys soul went from green to blue faster than I ever thought possible.

All I found myself able to do was grin at it.

Frisk put me down and launched herself into the thick of things. Two purple tendrils snatched the other human up. He cursed up a storm as he was hefted into the air. Then crashed into the floor. Several rapid times. Right then, seems Frisk was angry.

Found myself rather enjoying how he was being flung around like a rag doll. Though it was a bit unnerving to see her so vicious. Especially since I'd grown up around a smiling loving Frisk. Thank goodness she hurled him aside after only a few moments. Other wise I would have considered stepping in. As angry as she clearly was there wasn't any reason for her to kill the guy.

Even if he deserved it.

"Which branch." She huffed as he attempted to stand up.

"Heh. All in good time you bleeding heart." He got to his feet on shaking everything. A bit of blood now decorated the edge of his mouth. "As for now the way I see it you have one of two options. Keep attacking me and exact your revenge here. Or you can worry about saving him."

All of us followed to where he was pointing. Seems dear old dad was back together again. And starting to slip into what I assumed to be the void. Frisk looked as if she were torn between the choice. In all reality my vote was for finishing off the brat. We could get to my despicable father later.

Or never. Which was totally fine with me. Her entire form locked up, hesitating for the smallest of seconds. But with an irritated growl dashed over to my father. Damn it why couldn't she had just let the old bastard go? This left the brat have his way. But it was far from over that much I could tell.

Frisk gave a shocked yelp suddenly. Tore my attention from the other Human so as to see the reason for her making a noise like that.

Her two tendrils had reached out the full fifteen feet. Coiling around as much of the mass which was my father while she fought against the power of whatever was pulling her in. I was on my feet instantly and at her side in a heart beat. My own powers grabbed not only at her but my father much to my annoyance. The reason for this was simply because it became quite clear were I too loose him she too would vanish. But I wasn't exactly that well equipped for heavy lifting or other strenuous things like pulling heavy objects.

A set of arms captured me at torso level and started to tug hard.

"I've got you!" Andy reassured me.

Most of his voice was drown out by the groaning of void. Hurt my head just to be this close to it. Not even sure how Frisk was withstanding it. But she was reaching up grabbing a hold of our extensions and pulling. Wasn't enough we were still loosing more ground than gaining. More arms grabbed at me and orange joined my blue as we secured Frisk in place foremost.

After all we could try again with my dad. But we couldn't afford to loose someone as valuable as her.

"PULL!" Undyne ordered.

None of us questioned her simply started to do so in unison. One step at a time we began to see results. Wasn't going to lie this was very straining on us. Papyrus clearly wasn't use to this either. So his magic was getting eaten up like no tomorrow. Andy pulled away one arm as he then outstretched it fully in front of him.

That buzz of Human magic hit me again causing my head to spin in wild ways. Made me tighten my grip on Frisk even harder to keep myself anchored thankfully. After a few moments thick white wrapping slithered around his arm. Didn't stop until it reached his shoulder where I couldn't be sure what happened next. At least on that end. What looked to be large white strips of cloth sprang towards not only Frisk but my father.

"BIND!" He commanded.

I heard the slightly shocked squeak from her as her torso was wrapped up in white. Kid had game. And strong magic because once it was locked in place we started to pull quite a bit better. Sounded like it was taking its toll on him however. Given his struggling breath and slightly shaking arm. But Frisk regained control of the situation when we were about half way done.

Her power seemed to just spark when we needed it most. Wasn't hard to feel how her magic just suddenly spiked. Must have been her determination at work along side the magic. All of us gave one final mighty pull. And our reward was the god damned loudest pop I have ever heard in my entire life. All five of us – make that six actually – fell backwards in a heap upon the floor.

Seems we each had our own sound effect to go with it. Andy's being the most amusing in my eyes.

"A-Andy? Sans? You both good?" She coughed while sitting up looking disheveled as all hell.

"I'm good." I flashed a thumbs up.

"Hgn. Y-yeah." Andy struggled a bit with his words.

"You held on too long didn't you?"

"Yeah...sorry."

"Is it bad?"

Andy shook his head and let her over look his limb in question. Those were some nasty looking ligature marks. Kid could have lost his arm if we went on much longer. No wonder Frisk was looking so upset over this. Just another reason for me to have utter disgust in the thing we had yanked from the void. With a grumble my eyes turned to look at the lengthy bastard in question.

He too was struggling to get up. But he was as I recalled. Well aside from the new marks on his face. Looks like someone or something had gotten in a nasty hit on his skull. Served him right. Shook my head while trying to figure out why exactly Frisk had found it so damn important to choose saving him over her own revenge.

"How...how can this be?" He sounded just astounded.

"All in favor of home." Frisk held her hand up.

"I." Came the unanimous answer.

"Cool. Hm. How are we all going to get home?" She smacked her forehead. "Damn it I had the plan to get up here but not back. Lovely."

"bI believe I can help./b"

My father strolled over on his long legs. He still looked so professional in his black suite. Huh, seems he'd gotten taller since last I saw him. Annoying as hell. Frisk looked up at him and blinked. Then gave a content sigh.

"Oh man am I glad all that wasn't for nothing. Let me tell you would have been so angry if it had been." A smile broke over her face. "Anyways you said you can help? I'm welcoming it at this point in time. God knows we need it."

"I'm so pleased you can still understand me. However before I can make any promises we need to make sure I can actually leave this room. Less all your work be for naught Void Gazer."

"...My name is Frisk or Rin. Use one of those. Not Void Gazer."

"Or Ambassador." I quickly took her hand. "Is it wise to trust him?"

"Well most he can do is turn back to goop on us. And as we've seen I can yank him out so not sure he gains much from being stupid."

"Hm. Point." My hand brushed her hair back a bit. "You look like hell. Feeling okay?"

"Tired. Heavy. Drained. I want to go home and sleep forever."

"How about a weekend?" I chuckled trying to bargain with her.

"Only if you're there when I wake up."

"Always."

"Hey you two love birds! Seems he can get us home c'mon, I'm hungry." Undyne called to us.

It was a quick trip back given dad's abilities to teleport where stronger than mine. But it made Frisk sick to her stomach. After she greeted Toriel and Asgore she and I climbed the steps together then vanished into my room. She instantly flopped upon our bed with a groan. Heh poor thing here I'd thought maybe she was exaggerating how tired she was. Apparently not.

Silently as she stretched out over the bed my hoodie was peeled off then draped over the edge of my bed. When she felt the mattress press down under my weight her head lifted to look up at me. Without words I stole a kiss from her. Could have sworn she'd have pushed me back. Scolding me slightly because she might have been too tired. But there was no protest.

Just bemused humming into my mouth as our tongues pressed against one another. Heh...when was I going to learn that playing with fire was bad for me? Sooner or later I would end up getting burned. Didn't take a genius to figure out her body was close to heat. Though the signs were obvious to me there was little doubt in my mind she was over looking them completely. In hindsight perhaps telling her what to look for would have been the smart thing to do.

Like how she would feel as if her entire body was in an oven being baked into a pie. Or how these urges would grow stronger. Maybe even warn her that the vivid purple of her eye and bone armor would lighten in color. All in preemptive warning for what she was about to be enduring. But no, I sort of had just figured this would never happen. At least not so suddenly.

And I was an idiot for such thoughts. This was heat I was talking about. Of course it was sudden. That was one of the reasons it was so damn intolerable. Well aside from other things but the fact it could just not be there one second and on you the next was the primary one.

Wait.

When had we shifted to this? I now was looming over her. My little canines latched onto her shoulder from behind as she kept a pillow stuffed into her mouth. Felt my hands running over her sides stopping only to pay extra attention to the exposed bones. Crap. Wasn't she supposed to be the one close to heat and not me?

I wasn't really...but with how handsy I was being with her might as well have been. My shame however was easily over shadowed by the sheer fact that I wanted to escalate things. This wasn't going to end well. Wait. No this could work in both our favor. She had been showing signs but hadn't yet crossed that thresh-hold. Which meant there was still a little bit of wiggle room.

As a Human it seemed her body was easing into this rather than simply letting it over take her. But the cure for heat was a simple one. Mating, or at least sexual release. Perhaps by doing so now in a more controlled fashion her heat would simply never be an issue. Then again the other was just as possible. This could trigger it to become fully blown.

...It was a risk which had to be taken. God damn if this backfired I only hoped she could forgive me. I forced her to look at me with one hand then mashed our mouths together. Her taller form trembled under me as I invaded her mouth with my tongue once more. The sweet savory taste of apples could almost be a drug at this point in time for me. Forcing through the haze in my mind I growled against her possessively.

Caused her to pull back her entire face flushed because of our antics.

"Why don't you roll over for me? I promise we'll have a really good time Frisk." My voice rumbled against her back.

With a gulp and darkening face Frisk slowly rolled over for me. The sight of that golden skin under her shirt got me riled up slightly. Caused me to pull the fabric up to her neck so I could just drink in the sight of her. Those bones over her chest were thumping in time with her heartbeat. And her soul was in clear view of my eyes. Which was rather convenient.

Now normally a skeleton would just slip their hand into the rib cage of the other to grasp their soul. However I had to get those interlocking armor plates open before that could happen. Kissing from her lips, over her neck, then down her front seemed to be more than enough of an intensive to open up for me. Never would forget how it felt the first time my soul was fondled. Like every inch of my body was suddenly being pleasured all at once. A feeling which now my beloved was feeling at my hands.

Something about that was a bit empowering. Knowing my bony digits were the ones bringing her such a feeling. Well, it made my bones rattle softly. The normally red heart was now a vivid purple which I brought to my teeth with tender care. Really wished I had lips right about now. Oh well, supposed Frisk would just have to settle for my tendril and tongue.

Once it was secured in place by the former the later was free to flick over its smooth surface. Her soul pounded in my grasp making it a little hard to tease it at first. So I started off with tender kisses all over. Something to just reassure her everything was fine. Once that melody of soft whimpers and heavy panting slipped from her mouth I knew everything was going to be just fine. Next came my first ever taste of my mate's soul.

Carefully lapping at the right bend of the heart Frisk arched right up into my pelvis. Such a sweet nectar flooded my senses. A muffled string of curses came from the mouth stuffed full of pillow. Since she wasn't telling me to stop...well I decided to suckle the exact same spot which had just been licked clean. My hands grabbed at the hips of the bucking woman under me. Ngh she was making this impossible for me to focus on her pleasure.

"S-Sans." Her ragged voice begged for my attention.

"Hm? What is it Frisk?"

"I...need you..." She gasped for air. "In me please."

Damn near dropped her soul at that confession.

"You sure 'bout that?"

Her answer was a rapid nod of her head. Seems she was far too embarrassed to say it again. Can't say I hadn't had the thought cross my mind. What with her grinding against me like this. My grin softened as my hand trailed down her stomach. She was a bit over dressed at that moment.

[Too much not fluff...]

Every bone in my body was tingling. Hadn't felt this good in years. It was all made simply perfect by the warm arms wrapping around me sometime later. Couldn't keep track of much right now. Time just seemed so pointless when you were this relaxed.

"I can't feel my anything." She was so far gone her words slurred together.

"Just rest." I encouraged.

Not that I even needed to say it in the first place. She was fast a sleep before the words even left my lips. Part of me just felt better saying them I suppose. Got myself decent then covered her up. Might as well let her rest, she'd used god only knows how much energy today. And well I was a bit hungry so this worked well in my favor.

Pulling some of her bangs from her face came more out of habit than anything now I think. Gave me an excuse to touch my teeth to her forehead too. Knowing she was comfortably tucked in allowed me to at least some peace of mind. It had been easy to over worry these past few weeks simply because of her mutation. And now because of whatever the hell this other idiot of a Human was trying. Speaking of that little brat now that I thought it over he seemed to know quite a bit about Frisk.

Or had that just been my mind playing tricks on me?

My hand on the door knob I took a few moments to glance over the sleeping mass on the bed.

...Was she neglecting to tell me something? Nah, that Human just had to be playing mind games with me and her. I trusted her way more than some mind controlling, body snatching, brother killer. A grin on my face I closed the door behind me quietly. Didn't want her waking up so soon after all. And just like that my good mood was soured at the sight before me.

My ungodly tall father was there. Leaning against the wall a smile which I didn't much care for spread over his cracked face. What was he so damn pleased about? Forget it I didn't want to know. He could keep whatever thoughts were in his head to himself. Just shoved my hands into my pockets and walked on by.

"You know this is only delaying the inevitable Sans. Her heat is fast approaching." His calm demeanor made my bones nearly rattle.

"Normally I would ignore you. But you just had to open that stupid mouth of yours about Frisk didn't you?"

I might have been a bit drained from my activities with her but I would dare to wager that I still had enough magic kicking about to beat the hell out of this bastard. My eye snapped on as I spun around to face him. Bastard still had the gall to look so smug at my anger.

"Tell me are you planning on children with your little toy soon?"

"What the fuck did you just call her?"

"No Sans that is not the proper question." He pulled away from the wall and shot daggers down at me. "What is it that YOU call her"

My fist trembled in rage. He had to have known somehow this was a touchy subject for me. Like he'd been crawling around in my brain. Ugh, I hated how he could do that with observation alone. Gaster gave a small hum of disappointment before shaking his head. Tch arrogant fuck wasn't he?

"She's my girlfriend."

"That's a Human term and you know it. What is she to you really Sans?"

"..." My teeth ground against one another hard. "She...she's my...everything." Came my grumbled reply.

"Mate. That would be the proper word your looking for I believe." He heaved a sigh. "Regardless I am happy for you. It's very clear your magic clicks with hers. It means your children will be strong."

"D-did you just..."

"Well I do wish for some grandchildren. And she is a Human after all Sans. I'm certain I don't have to tell you what that means as far as your ages go."

She would die well before I would.

No. He didn't have to remind me of that painful fact. That loomed over my head enough. She could be taken from my life at any damn moment. Not just her age was an issue. Just the biggest hurtle really.

But did he have to make it seem like all she was good for was...was...breeding?!

God fucking damn it did I want to hurt him for that. Oh I wanted to just wring his neck until he was dead. Or maybe let my Blasters deal with him for me. Thankfully however my ears were not the only which had heard such remarks. White bandages from before snapped around my father's throat and limbs rendering his movement rather limited. A mighty yank and he was on his knees before the young man who now was moving away from the steps in order to be face to face with his catch.

"I will say this once and do not dare ask me to ever repeat myself you horrid creature." Andy spoke clearly all emotion stripped away from his words. "That woman you speak so carelessly of is my sister. And I will not allow you to continue insulting her in such a manner."

He pulled tighter on the binds, a wheezing gasp escaped the other skeleton's lips. "I have lost everything dear to me once. I will not allow for a second. She is my sister whom I love with all that I am and more. And I will kill anyone to keep her safe. My magic may be used to help but mark my words it can harm just as easily." Andy's voice became deathly serious. "Do we have an accord Gaster?"

"I believe so...yes."

"Good." The binds of white vanished. "Don't let me hear you speaking ill of her again."

He rose on shaking legs before stumbling down the steps. Andy stood in silence the entire time. Each step seeming to take an eternity for us both. Once it became clear he was now in the comfort of the living room those blue eyes softened and looked at me. His mouth opened and I waved whatever apology he had been forming aside. Kid was alright in my books.

"That took some very large balls. What sort of magic did you say you have?"

"Transmutation. Hence the ability to change the necklace. But that is not my specialty. Healing magic is. And well, what would a doctor be without bandages?" He gave a light chuckle.

"Not a very good one. Thanks for that. Almost lost my cool."

"We may as well be brothers Sans. You clearly love my sister. Weather she is your mate or girlfriend I know you will do right by her."

"Gah. P-please don't say that word any more. It's embarrassing."

"Alright. Now back to the reason I came up here. How is she?"

"Sleeping. And personally I'd like to keep it that way."

"So would I. Perhaps you and I can go to that bar you enjoy for dinner then?"

"Grillby's? Hey not a bad idea. Was just thinking about getting something to eat."

"Well consider it my treat then. Seeing as how I've never actually eaten there."

"Boy are you missing out. Best we fix that."
