Chapter Text
The smell of alchemical substances impregnated the underground laboratory, almost managing to cover the smell of Abomination that seemed to have stuck to the walls and floor of the entire manor. Luz still remembered the first time she had gone down there and met Amity's father, a man very different from the haughty rich nobleman she had imagined at the time. Now the place was quite different, although just as messy.
Instead of abominations and steampunk-style machinery, the tables were filled with cruets and bottles, stoves and glass vials, with a large black cauldron in the center of the room. They looked like a mixture of the alchemical tools of the Demon Realm and the Human Realm, including even a car battery with electric pliers. In addition to that stuff, several books and scrolls had been placed on a table, most of them concerning wild magic, studies on the nature of the Titans and chronicles of the years before Belos' rule.
Belos. The mere memory of that name made Luz feel the taste of bile on her tongue. Five years had passed since the day the tyrant had fallen just before reaching his goal of extermination, trampled to death under the feet of Eda, Raine and King. Yet sometimes, when she was tired and alone, she still heard the memory of that disgustingly calm and poisonously sweet voice, and it made her shudder.
In recent months she had begun to think more often about Belos. The past few years had been spent rebuilding the Boiling Isles, but now that the work was done and the free time had increased, the head wandered to many more dark places. And because of those thoughts, a new idea had come to Luz Noceda's mind.
"It was a Deus Ex Machina" Luz had understood one night when she could not sleep. The thought had caught her after hours in which she had turned in bed alone, Amity away for a conference on the ethical use of Abominations.
The defeat in Belos had been a day of celebration, but in fact Luz had lost. She safe the Collector but she was hit and consumed by the cancerous green fungus that was taking over the Boiling Isles. All the skills she had learned had been useless, every glyph or plan worthless and only the intervention of the soul of the Titan himself had saved Luz and her loved ones.
It had been a terrifying thought, perhaps made even worse by the fact that she had died (Or maybe she had just come very close to dying, even she had never really understood). Now that the Titan had vanished completely, there were no more second chances or respawns with superpowers, and the next time some threat hit the Boiling Isles it would all be in the hands of the witches and Luz... and both had already failed once.
So from that day, Luz had begun to study a way to summon the primordial energy she had used to save the Boiling Isles. She was more powerful in that form than any witch would ever have been, even more powerful than Belos. Some nights she had dreamed of that shape, to feel again the raw power of the isles themselves flowing through her veins, and when she woke up the emptiness was like a hole dug in the middle of her chest.
For four months, she had spent every second of her free time reading, experimenting, and exploring ancient ruins with Lilith. Only Amity knew what Luz was trying to do, and only because they lived together.
She and Amity had been living in Blight Manor for a year and a half now. Once the reconstruction of the Isles was completed, the twins had decided to create their own home in Bonesborough, finally being able to live as normal people and not the heirs of an entrepreneurial dynasty. Alador, on the other hand, had reached his limit, tired of being closed within those walls every day he had decided to buy a modest house in the countryside, wanting to live more in nature and away from any machinery, giving the house to the last child of the Blight.
A whistle caught Luz's attention, causing her to look up from the ancient history book she was reading. One of the stills was hissing, emitting a peach-colored smoke as the liquid of the same color boiled above the flames. She smiled and closed the book, leaning over and using a reinforced glove to grab the still and carry it to the large cauldron. A dark, bubbling tar-like liquid bubbled inside, emitting a foul smell.
"I hope it works this time," Luz murmured, talking to herself. This was attempt 13, and although she survived with only a couple of burns, she didn't want to buy a new cauldron for the sixth time in a row. With a deep breath, she poured out the contents of the still and immediately stepped back.
The cauldron began to shake and emit a dark smoke as the flames that fed it suddenly rose. The black iron lit up with the glyphs etched into the red-hot metal, the four colors she had learned to maneuver and modify. They became so bright that they turned white, and remembering the last time this had happened, Luz ran to hide behind a table turned upside down and specially reinforced with metal bars. She closed her eyes, waiting for the explosion. "Shit shit shit shit!"
Five seconds. Then ten. Fifteen. After thirty seconds she opened her eyes and listened, looking for any suspicious sound that indicated a possible disastrous reaction. After almost a minute nothing new happened, so she dared to lean over the edge of the table and look.
The cauldron was silent. The flames had faded, and the glyphs glowed in their normal colors. The smoke had taken on a multicolored and more ethereal tone, as if a rainbow itself was coming out of the shining inside of the pot.
A shiver ran down Luz's body who, abandoning all security, threw herself towards the cauldron and looked inside. The liquid had turned white as if it were milk and shone with its own light, now filling the air with an extremely sweet and honey-like aroma. The human felt the hair on her arms stiffen and a smile appeared on her face.
"I did it! I did it... right? Yes, at least I think so... aahhh! Luz, calm down!" she said to herself, slipping a hand into her hair and taking long breaths. "Don't get too excited or you risk being disappointed."
Calming down, she took a cup and a metal ladle from the table. She was amazed when she picked up the potion, and the white surface shattered, emitting small, multicolored glyphs as the ladle passed. She felt the warmth through the wooden cup, a terribly pleasant and familiar feeling.
"Calm down Luz, we need a test before screaming" she repeated to herself, trying to repress her joy. During the first attempt, which seemed like a success to her, she had been so stupid to drink the potion without even thinking about it. Luckily for her, this had simply locked her in the bathroom for the rest of the day. Since then she had taken guinea pigs.
She approached the large cage in the corner of the room. In true Luz Noceda style, the rat dens were laid out like a town, each house decorated according to the personality of each mouse. Of course, Luz had even made little hats for each of them.
"Let's see, who could I..." she thought, watching the rats that looked at her, probably waiting for food. She took a particularly small one, a female whom she had nicknamed Felicia Noceda, wife of Guan Carlos Noceda II with whom she carried out a coup d'état in the city of Rattopia sparking a scandal... She shook her head, having no time to remember all the intricate plot of the rats.
She always felt insecure in these moments. They were mice, but she disliked the idea of risking their lives for her experiments. Yet she did it for a greater good, to protect all those she loved. "I hope this time it goes well. I don't want you to end up like your mother." A shiver seized her thinking of the brutal end of Carmela Santiago Noceda. She took a spoonful of potion and placed it under the mouse's snout. "Forgive me."
Felicia sniffed the potion and began drinking it as if she had been thirsty for days, consuming the entire spoonful in a few seconds. Then, Luz waited.
The mouse initially remained still in her hand, calm and serene. Then she squeaked hard and bent over, waving her little paws. Frightened, Luz placed her on the table and walked away, a hand pressed to her mouth as guilt and failure assailed her. "Sorry! Sorry!!" she repeated to Felicia, her eyes sparkling with rising tears.
A black, purplish smoke billowed out of the mouse's mouth and skin, enveloping it as multicolored lights twinkled like stars in the dark. Luz fell silent and watched in amazement. When the smoke cleared, Luz let out a cry of joy. "It worked!"
Felicia's fur had changed from white to black and now appeared larger, with pieces of bone around her tail and along her back. The head had become a half-skull similar to King's face, with six curved horns intertwining behind each other's back. Arcane glyphs swirled around her, appearing and vanishing into thin air.
"I did it! I did it!" Luz screamed, grabbing Felicia and jumping into the air, holding her tight to her chest and twirling in joy. The mouse seemed a little dazed and confused by the transformation, and she understood her very well. If even a human had to get used to such an event for a moment, let alone a small mammal. Without thinking too much about it, she put her back inside the cage and headed for the table.
"I succeeded. Four months of work and I'm finally here," she said, looking at the cup of potion in front of her. She could already taste it on her tongue, the divine power that filled her veins and beat in rhythm with her heart. She took the cup and brought it to her mouth, but at the last moment she hesitated, wondering if what she was doing was right.
"I'm not Belos... I'm not Philip," she repeated to herself, something she had taken several years to accept. She wasn't perfect but she knew she wasn't a monster. That power would be used for the good of others and to protect those she loved.
She raised her cup and drank the whole potion in one go.
Intense heat erupted inside her chest. Her arms and legs began to burn and when she tried to scream she found herself on the ground, her breath blocked by pain. Then everything went black.
The first sensation Luz felt when she regained consciousness was pain. Her entire body ached as if she had run the longest marathon in the world, every muscle burning and throbbing pinning her to the ground.
For a brief moment of panic she wondered what she was doing on the floor, but she only had to open her eyes to remember the experiment and the potion. Next to her, the cup was lying on the ground, empty. Wondering how long she was unconscious, she turned her gaze to the laboratory clock, but when she did, she felt something hard, connected to her head, hit the floor.
She opened her eyes wide and moved her head slowly, now clearly feeling two bony protuberances that started from the skull and stretched until they touched the floor. A shiver shook her and she almost cried when she raised her hand and looked at them. "It worked..." she whispered with joy, looking at the transformed limb, a certain difference immediately jumped out at her.
During its first transformation years earlier, the hand had remained in human form, albeit with covers made of bone. (Or her fingers had become bones, she had been too busy saving the world to notice.) Instead, now it was a real animal limb, larger than before, with four huge bony claws. In the center of her palm shone the symbol that many years ago had burned on her chest.
"This is new," she thought, opening and closing her claws. She looked down, wondering if there were any other changes and for what reason they had occurred. However, the position and the poor lighting did not allow her a clear view, so she made an effort and stood up, emitting a sore snort.
At first she thought it was the simple confusion due to the transformation, but after a few seconds, while she tried to stay stable on her trembling legs, she realized that the table was much lower than before, while the ceiling had become closer. She had grown in stature, and, she quickly realized, not only in that. "What... what the hell are these!?" she almost shouted, blushing deeply.
Looking down she saw two huge spheres of dark flesh dangling from her chest. One of the few gifts that Camilla had never been able to give her that large chest that often attracted the attention of different boy, men and women (A couple of times even Amity.) Yet those giant breasts totally dwarfed her mother's, making them look like little more than apples next to watermelons.
"Why... why my tits..." she wondered, instinctively bringing her hands to grasp those two alien protuberances. She regretted it as soon as the strong claws grab the soft flesh, squeezing it with more strength she meant to use and unleashing a jolt of pleasure that ran all over Luz's body, making her gasp and emit a squeak of pleasure. "W-What... it’s happening...". Several times she and Amity had explored each other's bodies and Luz had always appreciated the witch's touch on her tits, but this time the pleasure seemed to have increased a hundredfold.
"A-Ahhh... ahhhh..." she moaned, her claws tightly clenched on her breasts. She feared that if she moved even one finger it would unleash another wave of pleasure, something that both frightened and tempted her. She was trapped in a cage in the middle, a frozen rush of pleasure that pinched every nerve without ever really going wild. It was then that she felt something else, something new, a growing tension between her legs. "Oh... What the heck is there now?"
She moved towards the large mirror placed against one of the walls of the laboratory. As she walked slowly, her legs still unsafe, she felt something warm and fleshy rubbing between her thighs. When she finally saw her reflection in the mirror, the mix of emotions was so strong that she let go of the grip on her breasts.
What she had become was very different from her very first transformation, even though she remembered it for many things. She had grown much taller than she had thought, almost touching the edge of the mirror with her horns, which had now become much sharper and more intricate. The dark fur covered only the arms up to above the elbow and thighs, taking on a shape similar to fishnet stockings, while the knees and rest of the legs were now completely made of bone, more like bird claws. The chest was completely bare and below the huge pockets of meat she could see a nice six pack on the belly. In fact, her entire body, where human skin was visible, the flesh appeared much stronger and more sculpted, but all this took a back seat to Luz, whose attention was focused on what was dangling in the middle of her legs.
From a thick bush of pubic hair bunched between her thighs emerged what could only be described as a column of pulsing flesh, far darker than her tan skin, black as a moonless night. Thick veins ran downward, to a broader, flat head, from which a clear, thick and honey-dense fluid was dripping on the floor.
"Why... Why do I have a dick?" asked Luz, looking at that mass of flesh, her arms trembling as if she were looking at a ghost. "Why this form is so… obscene? What did I do wrong with the potion?" Her breathing became rapid and she felt her face warm, her heart beating in her chest with force. "No, calm down Luz, calm down now. You'll solve this problem."
With horror in her eyes she felt a spasm along her cock and saw the rod throbbing, becoming angry and beginning to bend forward. It was a very strange feeling, as if a sleeping arm was waking up for the very first time. "No! No, no, no, no!" she cried out, moving away from the mirror and toward the alchemy table, her huge paws pressed to her head. "Think of cute and cuddly things Luz. Bunnies. Snakes. Taxidermy. Tacos. My Little Pony!"
She had to calm down and, above all, calm that... thing. Potions are temporary, even those so loaded with magic, and if not even the pure energy of the real Titan had lasted more than ten minutes, that obscene transformation would soon vanish. She just had to wait and clear her mind.
She tried to distract hermself by fumbling with the notes she had filled out about this new formula. The result was technically correct, but something must have radically changed the final effects she wanted. Maybe one of the products she had used had gone bad? Or did she have to apply the runes in a different order on the cauldron?
As she analyzed every possibility, an image passed before her eyes. Amity, lying on the bed and wearing only that pink lingerie that Luz adored, calling her with that seductive voice. It had happened the night before the witch left three days before, a couple of hours of sex and cuddles as a gift before separating. It was a sweet memory, but now Luz saw it in a much more obscene way than before, and the natural bodily reaction was not long in coming.
"No! No, stay down!" she said with a low growl, looking and feeling the cock stiffen between her legs, slowly leaning forward and swelling at the same time, veins throbbing larger than before. An intense heat pervaded her stomach, rising to her face made red by embarrassment and something more obscene. Without thinking, she grabbed the meat shaft and tried to keep it down between her tights..
A shiver ran through her entire body as she felt the sensation of fur and claws against the hard, sensitive flesh, getting angry and letting out a moan-like cry from her lips. An intense sensation like an electric shock pervaded her body, as if the nerves were all exploding together.
"Oh shit.. oh shit oh shit oh shit..." she repeated softly, trembling with the intense pleasure she was feeling at that moment. She began to retreat slowly, her legs suddenly limp as if she were about to fall to the ground. She had to lean her butt against one of the tables in the laboratory, her paws locked around that monstrous cock.
The still rational part of her brain told her that she had to get out of this situation. She could just let go of that thing, focus on something else, and stay calm until the transformation ends. Yet even as she was thinking about it she realized that it was a crazy idea, she needed to calm that needy beast once and for all or she would remain in this state, and she knew that there was only one way to do it.
Slowly she began to drag both claws on the ebony flesh, tightening her grip very gently. Warm, obscene sounds came out of her mouth as she felt the hard bony fingers pass over the pulsating veins. Each touch was a jolt of pleasure down her spine that shewed her brain like a milkshake, filling it with alien sensations and powerful madness. Not even the raw power of the Titan had made her feel like that.
"So good... s-shit... it's so damn... gooooood..." She moaned, arching her back and bending her head upwards, her whole body enveloped in intense heat, as if she had a furnace instead of her stomach. The skin began to shimmer, beaded with sweat, and even the hair was getting damp, especially the one between the thighs. Only in that moment she realized she has a tail too, as it lashed on the table and pushed things on the ground, but Luz was too focused on the pleasure to care about it.
The big hands moved along the entire shaft, up and down with exasperating slowness, pressing every pulsating vein and every sensitive area, from the base to the tip. And in their touch the cock throbbed in full ecstasy, now becoming a real arm of flesh similar to what Luz could identify as a equine cock. In a thin part of her brain, she wondered if she had become some kind of furry, but that idea was never answered, lost in the whirlwind of pleasure.
She had no idea how long she remained in that situation. Even time seemed to have bent to that moment, leaving her alone immersed in that ocean of sensations. Yet, at some point she felt a pressure between her thighs, just below her cock, and then she knew she had received the complete model. Two huge fleshy spheres pressed against the table, as big as two ripe melons, bubbling like small volcanoes as a feeling of emptiness filled her belly. She didn't understand exactly what it was, but instinct guided her to move her paws faster.
"Ahh... ahh... ahh... ahh..." Luz moaned, tongue hanging out, saliva dripping down her breasts and her eyes soaked with tears of pleasure. She was so close, oh yes, she felt like she was so close. Obscene images flashed before her eyes, images of every single time she had sex with Amity, her gorgeous body, her sweet face, and her delicious pussy. Those memories mingled with imagination, showing her beloved impaled on top of that cock, her face contracted with pleasure as she screamed her name.
It was wrong because the witch was a lesbian, yet she couldn't help it. The pleasure was too intense, the need impelling, and the mind too confused to understand it. "A-Amityyyyy!!" she shouted as she felt her muscles and flesh contract. She spread her legs in pure instinct and screamed when the white explosion finally happened. Thick cum erupted from the stiff tip, splashing on the tables, on the floor, against the cauldron, wherever it was possible. Luz didn't even notice, eyes closed and head resolved upwards, mouth wide open in the trembling of pleasure.
She didn't know how long she was there, trapped and could only feel that piece of flesh throbbing and contracting as the white river poured out. She only knew that at a certain point that strength and pleasure began to wane, allowing her to open her eyes and observe the obscene spectacle she had produced. She gasped, taking in the air and letting herself lie on the table, feeling the muscles warm and aching as if they had caught fire.
"It's done," she thought, too tired to even talk.
Slowly she managed to get off the table and get back on her feet, albeit with a shaky step. The cock was soft again between her thighs exactly like... Ah. How long had it been since she started? When she moved her gaze to the clock on the wall, her eyes widened. "AN HOUR!?"
Had she been rubbing that cock for an hour? How the heck had she managed to spend so much time masturbating without realizing it? Still, she felt a strange pang of pride about it, thinking that she had crossed the line of many guys and many porn stars.
Most worryingly, an hour had passed, and she had remained in that shape the whole time. How long would it take before she could return to normal? The doubt crept into her if she would ever return to normal.
"Okay, okay, relax Luz," she said to herself, taking a deep breath. "Amity will be back in a week. If the potion does not exhaust its effect, I will only have to create another one that will turn me back into a human." Only then did she notice the pungent smell that permeated the laboratory, and it was not the alchemical compounds. Steaming sperm covered the floor and tables, spreading that intense musky-like smell everywhere. "But first, it’s better I clean this place.”
At that moment the door of the laboratory opened suddenly. "Luz! There was a mishap and the meeting was brought forward, so I was able to... come back... before..." Amity's voice slowly faded as her gaze fell first on the disaster in the lab and then on the new and obscene form of her fiancée.
For her part, Luz wanted to say something stupid, as usual, a joke to lighten the mood or something like that. Instead, her reaction was a wide smile on her face, showing the sharp fangs, as her cock started to pulse once more.
