Heroes’ end



       The sterile white lab buzzed with an unsettling hum. Frisk stirred, vision blurring as she blinked away the remnants of sleep. A sterile metallic table was her unwelcome bed, straps holding her limbs firmly in place. Panic clawed at her throat as she saw herself alone in that eerie place.
       Then, a figure materialized beside the table, tall and shrouded in a long white coat. His voice, when he spoke, echoed strangely within the metal confines.
       —Ah, greetings, child. Welcome to my humble abode.
       Frisk’s voice was hoarse.
       —Wh-where am I? Who are you?
       The figure chuckled, a dry, humourless sound.
       —Forgive the unorthodox welcome. I am Dr. W.D. Gaster, and this, my dear, is my little corner of the world.
       Frisk’s breath hitched. Gaster. The legend, the banished scientist. Fear prickled at her skin, but a sliver of curiosity fought its way through. She remembered the information she found back in the abandoned labs, and the strange research that was being performed there, a grim undertone of danger filled her head.
       —You know who I am? —She rasped—.
       —Indeed. —Gaster boomed; his voice tinged with a childlike glee—. You are Frisk, the hero of all monsterkind. The one who shattered the barrier and freed us from the Underground.
       The weight of that title settled on Frisk’s shoulders. Her last memory was of her freeing her friends to the outside world and then returning to say goodbye to Asriel one last time, maybe she was captured as she tried to make her way back? The sight of Gaster, a figure shrouded in mystery and whispers, sent a shiver down her spine. What did he want with her and why did he do it in such a way when she had been nothing but peaceful with everyone else.
       —Why am I here?
       Gaster’s amusement faded, replaced by a glint of something akin to hunger in his shadowed eyes.
       —Curiosity, my dear. Unsatiable curiosity. You see, your journey, your determination... it’s a scientific marvel! And a scientist, well, can’t resist the urge to dissect, to understand, can he?
       Frisk’s heart hammered against her ribs.
       —Dissecting me? You can’t be serious!
       —Of course, not in the literal sense! —Gaster said, his voice regaining its earlier cheer—. I just want to know what makes humans tick, how their determination work and maybe… How to break it.
       He reached out, a skeletal hand hovering inches from her face. Frisk flinched, the straps digging into her skin.
       —My apologies, I had you tied in case you didn’t want to cooperate. —Gaster said, amusement returning to his voice—. I promise no harm if you do.
       Panic threatened to consume Frisk. She had escaped Flowey, faced down Asgore, even defied the very fabric of time itself. What else did she have to go through to reach peace? Until now she had trusted every monster she met, so it was clear she would trust Gaster too.
       —Fine, I’ll help. —She replied—. But only because Sans and Papyrus hand me no reason to not trust you.
       Gaster paused, his hand retracting slightly. An unsettling silence filled the room, broken only by the hum of the machines.
       —Hmm. —He finally murmured—. Sans and Papyrus, my old friends… Don’t worry, child. I won’t do anything they wouldn’t…
       A sliver of hope pierced through Frisk’s remaining fear.
       —And what is it you want to test?
       —Everything! —Gaster chuckled, a low rumble in his chest—. My dear, you haven’t even begun to think the reaches of my curiosity. But fret not, your participation will not be unpleasant. Consider it... an educational experience.
       Hesitantly, Frisk nodded. 
       —Excellent! —Gaster boomed, his earlier enthusiasm returning—.  Now, let’s get you untied…
       Frisk closed her eyes, feeling how the metal straps suddenly snapped open, freeing her completely.
       —Thank you… —She said, her voice stronger now—.
       Gaster hummed, a thoughtful sound.
       —Don’t thank me just yet… —Gaster continued—. First, I will need you to undress for me.
       Frisk had second thoughts about it right away, why did he needed her to undress? It made sense given he was going to experiment, but the fact that he needed her nude was troublesome at best.
       Meanwhile, Gaster was inpatient and quickly approached her, putting his hands all over her as he helped himself to undress her.
       Frisk wanted to fight back but Gaster was too scary even for her, she didn’t know a single thing about him or if she could best him in the ring of honour if needed be –all while she was getting stripped naked.
       Gaster on the other hand was surprised by her beauty. Her short figure, her flat chest and perky nipples, and most attractive of it all, her clean and tight pussy. Her whole body trembled as he looked at her, the chilly environment taking a toll on her composure. But it was just the start, Gaster was taking his time to admire her body, and his hands wouldn’t stop touching her every cranny.
       —So interesting, like our skin but not so alike… —Gaster mumbled—.
       Like his skin? It wouldn’t take long for Frisk to get an answer to that question as the mad scientist took of his coat. Underneath he wore nothing else, exposing his body right away as not bone, but some sort of white flesh that looked like such. He was as much flesh as she was.
       —Your tenderness… It has me excited… —Gaster sounded agitated—.
       Frisk would also notice his hands getting more and more possessive of her as his penis began to erect. She wanted to run away but it felt like maybe it was too late, maybe she now had to see this reach an end and hopefully survive the ordeal.
       All while Gaster was already having her lay on the metallic table once more but facing down this time.
       —Just so you know… —Gaster continued this now one-way conversation—. If you try something, I’ll tie you up again…
       He wasted no time, spreading her legs and posing himself into position. Slowly pushing his cock inside her anus.
       And without warning, Frisk felt Gaster’s member stretching her insides outwards with incredible force, making her cry out in pain and fear. But still, there was no turning back.
       As she writhed underneath him, Gaster whispered inaudibly in her ear.
       —You belong to me now, little one...
       Frisk couldn't believe what was happening. She knew it wasn't real, that everything was just a dream or hallucination brought upon by stress and fatigue. The only reality was the unbearable sensation of Gaster’s hardened cock filling her rear entrance. And yet, despite being terrified beyond belief, she found herself responding physically. Her inner walls contracting around the intruding appendage. Even though she didn't want it, she couldn't help but feel pleasure mixed with horror.
       But still, the experience remained unforgiving. With each stroke, she felt her boundaries pushed further and further until she realized she couldn’t escape anymore. 
       She tried to struggle, but Gaster held onto her too tightly, refusing to let go. His other hand gripping her neck, holding her still.
       Despite all her efforts, tears flowed freely down her cheeks as she struggled against her fate. Each thrust deeper than the last, driving home the painful truth that she was forever bound to him. That regardless of how much she fought against it, she belonged to him -completely.
       And just when she thought it couldn't possibly get any worse, Gaster began to spew words of praise and affection. How beautiful and sublime Frisk was, how perfect for him in ways others would find impossible. As his voice rose in volume and pitch, Frisk could do nothing but listen and take it. Every word stabbing through her heart like daggers of regret and despair.
       Frisk tried desperately to break free from Gaster’s hold, struggling against his strong grip on her body. But he was too powerful for her puny attempts.
       Sweat poured down her face, drenching her as she continued to fight against the inevitable. And yet, no matter how much effort she put forth, she could not win. For Gaster was relentless in his pursuit of dominance over her mind and body.
       Inch by excruciating inch, he forced himself inside of her, stretching her tender anal cavity until it ached with every movement.
       Yet even as she screamed in agony, Frisk found that she could not stop the act from unfolding. It seemed like a curse had been placed upon her, ensnaring her within its web of lust and submission.
       Each violent thrust drove deeper into her soul, tearing apart her innermost self. Yet somehow, she couldn't resist. Couldn't push away from Gaster's touch. Instead, she clung to it like a lifeline, grasping onto whatever small shred of hope existed amidst the chaos swirling around them both.
       As each moment passed, the experience became more intense, building towards some kind of climax that she was prepared for.
       Gaster began to cum inside her ass copious amounts of his seed. Filling up her insides like a balloon is filled up with water, her body growing in volume equivalent to that of the amount of cum he deposited on her. Frisk screamed in agony as she felt his warmth take over her, seeing her belly grow fatter and fatter.
       It wasn’t until he pulled out that some of the excess cum made its way out, barely changing her new shape. She couldn’t believe what just had happened! Her mind going blank as she tried to grasp for dear life, feeling as if she could die at any moment. But Gaster was not yet done with her.
       Without losing much time, he was now fucking her pussy just as relentlessly as he fucked her ass, making yet another mess of her.
       Despite everything, Frisk couldn’t help but feel a strange sense of pleasure coursing through her veins. Despite being torn apart, there was something satisfying about submitting fully to Gaster’s desires. About giving herself up completely.
       As he continued to brutalize her, using her own body against her will, she could feel herself slipping further into the abyss of pleasure and pain.
       It wasn’t long before she found herself coming undone, reaching a euphoric release unlike anything she had ever experienced before. It felt as though the world was falling away, leaving only him and their connection behind.
       After a while, Frisk started to become used to the intensity of the experience. Each subsequent thrust became easier for her to handle, as if her body had grown accustomed to the constant stimulation. She was beginning to enjoy the power dynamic between her and Gaster.
       By the time Gaster came for a second time, she was completely lost, her mind gone and replaced by sheer submission. His cum filling up her pussy, filling up her womb.
       Frisk grew multiple times larger just from that, it was now more Gaster’s cum than Frisk herself. A receptacle for his seed.
       And he was surprised, she was able to survive his atrocious act and even submit to him, no clue she was able to fight Flowey, Asriel, Asgore and all those who opposed her as she made her way to the barrier. Her determination was such that even after being broken by his act of rape, it holds her in place just enough to keep her alive, to help her survive whatever challenge she had to face.
       Gaster could not believe it. He had to taste this even further, see how far he could push her before she breaks, if that was even possible for a human with such a strong soul. He knew there was only one thing he could try.
       It was time to swallow her up. He approached her legs as Frisk saw his jaws stretching to an impossible size. She wanted to fear for her life but somehow, she no longer had the strength to fight back –besides, his wet mouth felt warm and welcoming to her; the tightness of Gaster’s insides as they made way for her to slowly slip in, hold her like a weighed blanket. Her cum-filled womb being pressed as she was sent to his stomach, light slowly fading to black as her head was last to be gulped up. Ultimately resting in his stomach.
       Time felt like it had paused at that moment, she could feel his warmth engulf her but nothing else. She simply laid, letting her body get used to its new surroundings.
       But this wasn’t the test itself, but just preparation for it. Gaster, now with Frisk inside of his belly, sat down for the actual experiment.
       He took his cock and arranged his body so he would penetrate his own belly button. An odd position for sure but one that would prove to be most delightful. It wasn’t even the pleasure that he got from penetrating his own body, but what followed afterwards.
       —Go on, I bet after the first tests you must be hungry. —Gaster talked to his belly as his cock slip inside—.
       Frisk could see much, but could feel Gaster’s cock reach her mouth, her opening it out of reflex as she sucks on it. Sucking on it like a baby suck on a pacifier or a milk bottle, struggling to get something out of it like a hose.
       Gaster felt more than pleased as soon as he felt her mouth cover his dick, unable to help himself he would begin to leisurely fuck her face as he relaxed on the chair –moving his belly up and down as he could no longer push her instead, but being that she couldn’t move away either, it proved a good substitute.
       —There you go… See? As long as you keep cooperating you will be… quite fine… safe.
       He could feel her struggle from time to time, but not once did that worry him, as long as she kept complaint to him.
       —And. —Gaster continued talking to her—. As long as you do a good job, you will have plenty of food, and fresh air, courtesy of my cum. Doesn’t that sound… enticing? I bet my belly makes for a nice, warm bed.
       But regardless of how nice Gaster made it sound, it was clear that the winner here was himself, having frisk provide him with pleasure on a daily. Best part of it all? He could do this for as long as he wanted, on the excuse of “recording” his “results”. All but an excuse to fuck her for hours.
       Hours where she would move around his stomach to try and position herself in a way that made it easier for her to please him. Covering his cock in saliva as she ravaged him in hopes of being fed as promised. Sometimes finding ways to get fucked from time to time as she became more and more lenient and more and more submissive to him, getting obsessed with his spunk.
       They even developed routines. In the morning Gaster would slide his cock up his belly to feed her breakfast, a pleasurable morning each day as she would lick and suck him off with excitement, ready to fill up her own belly with his cum. Stroking him and trying to take him in as much as she could; with some ever so often progress being made as she would choke on just an extra millimetre each time.
       In the evening, she would move so when his cock slid in, he would fuck her pussy as soon as it made it inside, and then she would try her best to grind him over and over, only feeling satisfied after her womb was bursting with his seed. Her pussy never getting sore thanks to the humidity of his stomach.
       And during the evening and late night, a double serving as she would let him fuck her rump for hours before having her well-deserved dinner.
       For her it was like a lifeline as time went by, the more she took him the better she felt, almost like a fountain of youth of sorts, she never felt a day older.
       It was so vital for her; any actual food Gaster would eat she would not feed from either. She knew the more he fed himself the tastier his cum would become; so even thinking of reaching for other forms of nutrients became a sin for her.
       There was no more research to be done, yet both continued this cycle for the rest of times. Gaster was simply so proud of his success that it was a matter of time before he showed off to his brothers Sans and Papyrus.
       Both impressed with what he had achieved. Eventually persuaded to get a human of their own now that the barrier was down. But not any human would do.
       They were certain Gaster had picked the kid for a reason, so they too looked for a kid of their own, they even went as far as to assume the age was crucial for the utmost pleasure, only looking for anyone on the age range of Frisk.
       No one knows how many children they captured, how many were lost before the right candidate made it through, but eventually they too would find their own “Frisk” to keep them happy and pleased.
       It makes you wonder how she would’ve felt knowing that her actions brough upon a new era of human hunting, but being so content with her new life, one could wonder if she would instead feel bliss knowing that others could now experience her fulfilling life.
       Regardless, now the three monsters were parading happy and pleased as the three of them had a human of their own to please themselves whenever they wanted. Sometimes even getting together to fuck their own belly buttons and trial random challenges in the likes “who finishes last” or even going as far as to fucking each other’s tummies to experience the other’s prey.
