Luna grunted as she yanked at the staff in her hand, the glowing rope coming from its tip pulling a floating cart through the portal she just came from, carrying a wooden chest atop the cart. Her long golden hair tied in a messy bun on her head. Her robes torn and splattered with green blood. She sighed with a smile as she looked around the landscape, the familiar tower that her adopted mother and master resides in. Knee high clay, wood and stone golems roaming about, tending to the fields, harvesting herbs, and defending the surrounding. Luna continued pulling her luggage through the field, going to the stable at the back of the tower. The chest began rattling as she approached, the lid kept shut by the thick, mithril nails bolted through it. The chest, of course, was a mimic, the relentless beast unwilling to let up in its assault and forcing Luna to use up most of her reserves trying not to kill the foolish creature. The reason she needed it alive was her master’s ultimate project, a way to create the perfect creature.
 
 
In her quest to assist her master, Luna had roamed the lands, capturing a Titan anaconda as well as a winged lion, both much easier to weaken and capture than the seemingly tireless mimic. At least her task is at an end, and she is excited to see what her master will create. “Master, I’m back~!” She says excitedly as she pushes the door to the stables open, freezing in shock at the sight. In the center of the stables, surrounded by the cages containing the two sleeping targets she had captured, is her master and mother, Celeste, completely in the nude. Her shapely body, wide, child bearing hips and bountiful breasts only covered by her long black hair as she laid out on a table. That isn’t too concerning, as Luna had learnt that some of her mother's bigger spells require direct contact with her materials. What stunned her was what was looming above her, supported by two beams that cut through the stables. A massive Baltarian war horse, creatures used by a race of giants that live far away, its front legs raised up above to the point that the horse’s head reaches the roof. The creature’s erect member is visible for all to see as Celeste strokes the shaft between her breasts, running her fingers along the taut sac containing head sized orbs.
 
 
Celeste doesn’t acknowledge her apprentice's arrival till she is finished with whatever spell she was doing on the creature, giggling as she sees the horse tries to cum, its cock twitching hard as its sac clenches, unable to shoot its seed. “Welcome back, my little sunshine~” Celeste cheerfully calls out, rushing to hug Luna. Her apprentice recoils slightly at the smell of horse musk on her master, but leans into the hug regardless. “Is the horse related to your project, master?”
“How many times do I have to tell you to call me mother, Luna~?” Celeste chuckles, as she kisses Luna on the forehead. “And yes, it will be the vessel to melt down the creatures that you collected, as well as the core to bind them all together.” Luna looks a bit confused, looking around the room but seeing nothing resembling any core.
“What core, Master? I don’t see any core.”
“Why, it is you, my dear apprentice~.” Celeste coos, stroking Luna’s hair as the girl freezes in surprise. Her adopted mother, who took her in after purchasing her from a slaver all those years ago. Taught her all the magical arts that she became adept at. She is trying to mentally process why would she waste all this effort in just melting her down. Seeing the confusion and shock in Luna’s face, Celeste coos. “Don’t worry, my sweet child. I won’t do anything to hurt you. You learnt much from me, enough to survive this. And when it is all over, we will truly be mother and child~.”
Luna was clearly confused by now, pushing herself away from her mentor. “”W-what do you mean?!? I cannot survive being melted! T-that’s impossible!”
Celeste was hurt by her apprentice pulling away, but doesn’t force the matter. “Not with what I taught you. You remember the magical circulation technique I taught you, to increase your arcane saturation?” She asks, waiting for Luna to meekly nod before continuing.
“It has a secret use, one I used to regenerate my body when needed. I have been through the melting and regenerating process many times already, though yours’ will be a bit different.” She reassures, smiling as she sees Luna smile and nods in reply. “Ok.. mother.. I trust you…”
 
 
----------------------
 
 
“Where did you get a Balatarian war horse anyway? Aren’t they regulated?” Luna asks, as she watches her mother.
“I got it from a friend of mine, who tried making pornography crystals featuring the stud you see here… Not expecting the horse to grow this big when their bodies are full of lustful drugs, the fool.” Celeste chuckles in reply as she goes to the horse, giving its cock a playful slap. “Good thing I can fit this monster, but not so good for the girls he hired for his deeds. With no one wanting to buy a sex crazed war horse, I took it off his hands at a massive discount~.”
Luna shook her head at the tale, but kept her comments to herself. “So, how are we getting the subjects in..?”
“Easy, we just push them down the cock, and into his balls~.” Celeste explains. “I would need your help lifting the mimic up, but the other two should be easy. He was trained for this already, but you best get naked first, so your clothes don’t cause any issues.”
 
 
Receiving her orders, Luna hesitantly strips, still embarrassed about being naked in front of Celeste, before helping her lift the still bound mimic onto the table, her eyes widening in surprise as she sees the horse’s cock opening up to consume the box shamed creature. She gives the full orbs a gentle touch, feeling the hard form of the mimic within. The horse itself looks like it is drowning in pleasure, but Celeste pays it no mind as she opens the cage to the next subject, the still asleep titan anaconda. Luna starts feeling a heat well up inside her as she watches the member slurp up the massive snake, its other orb filling up nicely with it. By the time the winged lion was safely within the horse’s balls, Luna was rather eager to join them. Seeing the horse twitch in unbearable pleasure, she runs her hands on the creature’s sac, the mimic and anaconda in the left, and the bigger lion in the right.
 
“Now, Luna, I know you are excited.” Celeste comments, chuckling as she sees Luna flinch at the remark, pulling her hands away from the overfilled orbs.. “But you have to remember, focus your magic within yourself, and then draw in all their essence.” She then gives Luna a hug and a kiss, smiling at her apprentice. “Don’t worry, even if it does go wrong. I’ll take care of you.”
Luna smiles, replying with confidence. “I don’t think anything will go wrong, mother… You never did any mistakes before~” Celeste chuckles at that remark “That is true, my dear child. Now , I know this experiment isn’t time sensitive… but our friend seems to be really pent up. We should give him release soon.”
 
 
Luna giggles, nodding in agreement, before bringing herself towards the horse’s throbbing penis. Having already seen it slurp down creatures bigger than she is, Luna wasn’t worried about the possibility, but was thankful to be the last one in, the minor concern of being crushed under the bulk of the others tingling in her mind as she slides her head into the musky shaft. Luna yelps in surprise as she feels it sucking her in, her legs instinctively kicking about as she gets devoured by the hungry shaft, precum lubricating her way down. “My, you really are eager~” Celeste teases, as she notices how moist her daughter-to-be is getting, giving her apprentice's slit a lick as she helps push her deeper. The warm, throbbing meat around her pulls her deeper, her mouth filled with the taste of salty precum, her legs soon disappearing down the shaft.
 
 
Luna squirmed in pleasure as she is massaged by the shaft, and soon finds herself deposited onto soft but damp fur. Opening her eyes, she realises she is in the horse’s right ball, laying atop the still sleeping winged lion. Luna moans as she feels Celeste pressing down on her form, her slit grinding against the thick fur. As pleasurable as it was, though, Luna knew what she had to do, assuming the horse can’t hold for much longer. She began channeling her magic through her very core, circulating it in a steady rhythm, creating pulses of mana as she meditates. One of the runes etched onto the horse’s sac begins glowing in reaction to the mana, and Luna could feel her solid form slowly melting, the fur she is laying on turning into a similar gloop and begin mixing with her.
 
 
As she feels herself mixing with the lion, she could sense another core. The concentrated essence was an alluring power that Luna gleefully snapped up, drawing into her core as she let out a gurgled roar, unable to hold back the bliss of the intoxicating power. Eager for more essence, she can sense the essences of the other two sacrifices, separated by the flesh of the horse’s orbs. Determined to get her prize, she pulls off a chain of mana that is circulating her core, pushing it into the flesh that barrs her, and starts to feel the horse’s orb melt at her touch. Celeste, who was eagerly watching the bulges in the horse’s sac slowly round out, widens her eyes in surprise as the horse tries to cry out in extacy inducing pain, his balls being melted down as well, releasing his prisoners into his untouched sac. With the orbs no longer in the way, Luna absorbs the essences of both the snake and the mimic, the latter putting out more resistance than the rest possibly due to it being the only one awake during the ritual. As she brought the last sacrifice’s essence into herself, she reigned in her mana once more to focus on herself before noticing something. A faint essence, one more that she could take, but the subject not as affected by the spell that it was still hanging on dearly. More power was always appreciated, however, and Luna lashed out at the essence, weakening its hold on the body as her own fully melts down, into a tiny speck in the sea of seed.
 
 
Realising what had happened to her, Luna eyelessly gazed all around her. Millions of competitors, all rivals to her goal. She instinctively knew what she must do, she must be the last one standing to cement the success of her master’s grand plan. And so she consumed and consumed, growing and growing, bigger and bigger, till she was the only one left within the sac, ready to reach her destination.
 
 
-----------------------------------
 
 
Celeste watches in awe as the horse’s sac rounds out into a singular sloshing mess, the creature foaming at the mouth as its cock yearns for release. She is glad she didn’t take the easier option of renting such a horse, doubting she could ever return it as she laid herself out on the table, rubbing her slit against the throobing member. Levitating her body, cries out in pleasure as she impales herself into the horse’s cock, her cervix widened to allow the rod access, a spell of her own perverted making allowing her body to take it easily and much more. She pants as she pats her bulging belly, edging the horse some more as she focuses on her apprentice's mana signal, waiting for it to calm.
 
 
A minute pass, then two…. The horse looks like it's on its last legs. Celeste then felt Luna’s mana steady, and she released the seal sent on the horse, finally allowing it to cum. The horse neighs in pleasure as it finally shoots its massive load, bloating the witch’s womb full of seed… or what should be seed. Celeste had a pregnancy sensor spell placed upon herself, and with the amount of seed bloating her womb, it should have activated by now. Sensing something off, she glances down to the shaft, her eyes widening as she sees a massive bulge struggling its way towards her, crying out in pleasure as it widens her already stretched pussy. The singular, head sized sperm forced its way into her womb, and began squirming about within her, sending Celeste into a series of mind shattering orgasms.
 
 
As Celeste goes out of commission, something strange happens to the horse. Starting from the head, it begins melting like wax, its cock still shooting more and more of its seemingly infinite load into Celeste’s already massive womb, her belly bloating out and spilling over the table from the weight. More and more fresh seed made from the horse’s very own body gets shot into her womb, only to be consumed eagerly by the already fertilized egg, growing more in size from its initial expansion after fertilization. Soon, the only thing left of the horse is a still twitching cock, lodged deep in Celeste;s womb, barring any release in pressure, the witch’s own body slowly going to work absorbing what her apprentice turned child couldn’t..
 
 
------------------------------
 
 
Celeste woke up from her lust induced sleep, her head groggy from her various orgasms. She found herself completely covered in dry horse seed, the remains of the creature as it literally liquified above. She wanted to move, but she was pinned to the table with the weight of her belly, the slightest movement caused the horse cock still in her slit twitch in excitement, eager for round two…. Or fifty. Using her magic, she just pulls the cock from herself, the spent fluids gushing out of her slit and relieving the insane pressure in her loins. She couldn’t help but cry in orgasm once more as she was drained, watching her belly shrink back to a more manageable level. She was quite surprised to find that, when her womb was finally empty of fluids, she still had quite a belly. Reaching to feel the watermelon sized bulge, she smiled. Her adorable Luna had done it, and even more than she had hoped too. She could just feel the power of the being growing in her womb, and was eager to see what had become of her. Of course, the cock was not forgotten, but as much as she wants to play with the living creature turned sex artifact, she couldn’t risk hurting the child within.
 
 
Months would pass, Celeste soon being forced to rely on her many golems for even the simplest of tasks as the weight of her growing child forced her to become sedentary. That is, until one day when she was doing her usual talks of affection to her child, showering Luna with affection, excitement, but also a bit of annoyance at her lack of mobility. Unknown to Celeste, Luna had awoken within her, and upon hearing her mother’s grievances, focused on herself once more. Luna, using the abilities of the flesh of the shapeshifting mimic, shrinks her growing monstrous form to that of a human infant, something within her letting her know it would not hinder her development in the slightest. Celeste was of course, surprised by the change, giggling at the clear evidence that Luna was the one within her. Of course, shapeshifting only changes the shape, not the mass, and her belly was still just as heavy. Celeste pointed that out, thanking Luna for the unneeded and ineffective assistance, but informed her child to do this when it comes time for her birth.
 
 
After what totaled to a year and a half of growth, Luna was finally ready to leave her new mother’s womb, her body fully grown. Celeste could feel a change within her, as she continues to lay on her side in her bed, Luna having grown bigger than she is in the time. Feeling her water break, Luna began reducing herself to a more manageable size as Celeste pushed. With Luna’s help with her trying to crawl out, the birth was thankfully rather quick, Celeste struggling to cradle her newly born child due to her immense weight. She eventually gave up, much to Luna’s amusement, and laid on her side so her child can suckle on her breast as she deals with the afterbirth and umbilical cord with her magic. Even as a human, Luna looked alluring. A little tuff of golden hair on her head, eyes that shift from that of a snake, to a more normal pair of blue human eyes. Between her legs lay a rather cute penis, which surprised Celeste, until Luna revealed she still had both, her slit hidden underneath her member. “This new form is amazing, mother~.” She coos, after finally drinking her fill, giggling as she is hugged. “Well, how about you show it to me, then~?” Celeste urges, as she helps Luna move outside, the reborn apprentice needing some time to regain her sense of balance.
 
 
When they finally reached the outside, Luna focused. Her body began to grow and expand, her butt growing out as her legs split into two to support the growing rear. Her feet turn into lion-like paws, a coat of gold fur soon covering her lower body. At her rear, her tailbone grows out, expanding and elongating till it lets out a pleased hiss, fully forming a snake that is attached to where the tail would be.Meanwhile, her human top stays relatively the same, only growing in size to match her massive lower body. A mane grows around her neck, the same color as her luscious fur, though still looking rather infantile despite her size. To finalise her transformation, a pair of glorious wings sprout from her lower body, near the shoulders of her front legs. With a few test flaps, Luna soon got herself flying, laughing gleefully as she soars through the sky, much to her mother’s joy and amazement. After a few laps around the tower, she lands and rushes to Celeste to give her a hug. “Thank you mother, for this amazing gift~.” She coos, giggling as she realises she is taller than her mother in this form. “I’m glad that you love it, dear Luna. It seems this experiment is a resounding success~.”
 
 
And so, the two continue to live happily together, Luna taking her mother to far off lands. Unknown to Luna, her mother already has another idea planned, but she will wait till Luna is sexually mature before letting her know about it. As much of a perverted witch she is, she still has her limits after all, and doing a lewd experiment on her newly born child is one of them. She just hopes her body can last that long...
