Chapter Text
Evil was never truly defeated.
It was a cancer. A rot from the very core of the world.
Never vanquished. Just stalled.
Inevitably. Evil returned.
The Dark Lord rose. He raised war across the continents.
And was defeated, but only through grace and the humblest of heroes.
Until he rose anew.
For victory was never the Dark Lord's lot.
It was ruin.
For the world.
And for himself.
But in time, even ruin could be foiled.
And now?
Ruin's name was Alice.
She was the prophesized doom of the age.
Except ruin did not find herself in poverty. In strife. In any environment which would let hate fester. Instead, ruin was found on a farm.
A rather normal farm at first.
Alice working there for her parents.
With her elder sister.
She was largely content.
And largely distracted.
Alice was a young woman now, and as oft happens, Alice was distracted by thoughts of lust. Of the birds and the bees. Or in this case, the cows.
Yet the stain of horror did not leave Alice or her farm unchanged. Dark magics that had been intended to let her conquer and ravage the world, instead sort of curdled.
Twisted and tamed by Alice's growing desires.
Not for ruin. But for milk?
Alice had grown. And kept growing, even after such growth should stop. Well on her way to nine feet tall now. Beyond the height of any champion of goodness on this world. Yet, her rise was still hidden. Her rise did not bring alarm.
The world continued as if everything was normal.
Even as Alice's family shifted.
Even as the cow's shifted.
The cows were rather the problem.
The great reason Dark Lord Alice had not sought to conquer the world, or at least the tri-county area?
It was the cows. Or rather the minotaurs. The cowgirls. Cows risen to walk upon two legs, to carry themselves with great strength. To be the perfect shock troops for Alice to break the will of the living.
Alice didn't see them as shock troops. Instead, she was rather distracted by them.
It was the breasts.
For a cow to have teats, of course, was not unusual. But, well, when they made sounds of satisfaction at getting milked, the entire experience was usually far more detached.
Far less compelling.
Alice gulped. And gave another squeeze.
The latest minotaur was on all fours for her. Raised up over a bucket. And Alice was on her knees, reaching out with both hands. Squeezing. Milking. Trying to ignore just how good this seemed to feel for the minotaur.
Trying to ignore the rising hardness in her overalls.
Oh.
Alice had a cock. It seemed rather tied to the very idea of a Dark Lord. All Dark Lords in legend had a dick. Especially the women. One even was rumored to have three. Alice wouldn't have envied her.
One cock was far too much as it was. The terrible monstrous thing, the pillar of sin, the doom of virgins, the calamity of lust. The obnoxious stiffie. It was pushing up further along her belly, straining against the denim.
"Not again!" Alice whined to herself.
She had to milk all the cows today! She couldn't stop to jack herself off for a third time! Alice was running out of places to hide the cum. And she couldn't shirk on her chores.
She really wanted to show her parents that now that she was 19, she could handle increased responsibility. That they could trust her. That she wouldn't spend all day pleasuring herself.
Again.
"Almost done." She whispered to herself, closing her eyes. Trying to imagine anything else that could produce the noises the minotaur was making. Except whatever she imagined was inevitably worse. It didn't help at all.
At least she was alone. It was worse when...
"Alice! What is taking you so long?" A voice teased from the edge of the barn. Alice shook her head. It was Mary. Her older sister. Who never seemed to give up on a chance to tease Alice.
"Mary. I'm trying to work! We can talk later." Alice said, eyes still clenched, barely holding it together.
"Were you jacking off again when you were supposed to be working?" Mary asked, tutting as she approached. Mary had grown too, if only from proximity to Alice. Well over seven feet tall, destined perhaps to be Alice's right-hand woman.
Or sister-slave-bride.
"No. I'm fine!" Alice growled. Control clearly slipping.
"Aww. Need me to help?" Mary asked, finally reaching up to rest a hand on Alice's shoulder.
And that was enough to set Alice off. She turned about, opening her eyes, taking in the sight of her older sisters curvaceous form. And then moving, her body rippling with muscle as she shoved her sister down. Pinning her to the ground.
Starting to mount her already.
"See, that's the spirit Alice!"
Mary said, encouragingly. Expecting, wanting to do just this. She had even come out to the barn, wearing her sundress. The one that always got Alice hot and bothered.
"This isn't fair Mary!" Alice had tried so hard to behave. To try and hold her lust in. She had even nearly finished milking the minotaur without incident. Without going too far.
Without fucking the entire herd.
Again.
"You can't just let me work in peace." Alice pouted, her cock now pushing up between her own breasts. The terrible glans nearly poking out from her own cleavage.
But Alice had a better target for her cock. She unbuckled her overalls, and let the bib fall down. And then tucked it back, finally freeing her cock over her sister.
It was a cock that even the minotaurs had trouble taking. But Mary? Mary took it with grace. Her entire body altered to better accommodate her little sister's lusts.
"That's it sister. Let it all out. Show me how much you care for me." Mary encouraged, slipping the sundress off her shoulders. Pushing her chest out. Hefting those heavy tits up. Giving Alice a nice valley to just... push through.
And Alice did just that. Grunting as she fucked between the soft flesh. Feeling the contrast with her own hardness. Feeling the heat of it all. Feeling her terrible cock trapped in the only chest that could truly encompass her girth.
And she started to buck and thrust. Long thrusts, using the full length of her cock. Sliding through that valley of tit-flesh, through that tunnel of mammaries. That shrine that Mary pushed together just for her.
Each full thrust, each movement, tugging on the wall of tit-flesh. Making both breasts wobble. Making those nipples dance. Driving Alice just a little bit madder. Driving her to want more. Her cockhead pushing against Mary's face with each full thrust.
As Mary extended her tongue to greet her sister. To lavish attention on the tip. To coat that tip with saliva. To drink in the precum that was already pouring out of that cock. Yet it wasn't a smooth enough movement to let Mary fully suck the cock that was currently fucking her tits.
Alice's thrusts were too wild.
Too unsteady. Her strength enough to shake Mary's entire body. Mary wondered from time to time how her sister had gotten so strong. Wondered how Alice had such an amazing cock. But those wonders drifted away from her each time.
Everything was perfect in the world. Why worry?
Alice too had trouble wondering. While she was at times annoyed with Mary's eagerness, such protests were never any deeper than her words. The difficulty with Mary, was that Mary always did exactly what Alice wished her to do.
Even if Alice never expressed the wish. Even if Alice stated the opposite. There was Mary. Ever supportive. Ever lustful. Offering her body to her little sister.
To her terrifying monstrosity of a sister.
And Alice enjoyed every moment of it. Even as she complained. Mary was terrible for Alice's self-discipline. But Alice never tried terribly hard. And Mary's presence was always a wonderful excuse. A chance to just indulge.
To take what she wished. To ravish her sister's body. Thrusting wildly, pushing through. Painting her sister's face with precum alone. Until finally, in that channel of tits, Alice finally lost herself. Body going rigid as she roared. As her cum flooded out across Mary's face. Painting her sister in cum. Painting the straw of the barn in cum.
Mixing it in with the caked remains from the day before.
"There, now isn't that better, little sis?" Mary asked, smiling and licking her face slowly clean. Knowing that this was far from over.
"No! You know I can't think like this!" Alice raised herself up, cock still rigid. A single orgasm, even as potent as it was, wasn't enough to calm Alice down.
Far from it.
Alice grabbed her sister, lifting her up with ease, though with two arms. Most people Alice could lift with just a single one. Alice tossed Mary against the wall.
Mary caught herself. Bracing herself there. And then reaching back to lift her sundress. Revealing the full of her ass. Showing off just how soaked her pussy was. How truly eager she was for her little sister.
Alice charged forward. Crashing her hips against Mary's ass cheeks. Her cock spearing between Mary's thighs, the charge too eager to actually strike true. But those thighs alone were pleasing enough. That belly pleasing enough and even starting to push through those same tits from below.
Alice kept thrusting, with each thrust, grinding her cock across Mary's pussy. Across Mary's clit. Mary hadn't grown a cock like her sister had. Neither had thought to speculate why. Perhaps it was prophecy? Perhaps it was just Alice's preferences?
And Alice's preference was exactly this. Spending time with her sister. Fucking Mary's thighs hard enough that the barn shook. The strange and twisted texture of her cock grinding against Mary's clit. Driving Mary mad.
Mary came at least once before Alice pulled back. Before Alice lined her cock upwards, pressing the engorged glans at Alice's pussy. The one pussy truly made to take her.
But even then, it was a stretch. It was a struggle to push in each time. As Mary started to cry out like a cat. Her body once again stretching, once again molding itself to take Alice's thronebreaker cock.
Alice didn't pause until she slammed the tip against Mary's womb. And even then, Mary's well-trained cervix could only slow Alice's pursuit. Could only delay the final penetration. Could only drag it out. Until that too was stretched open.
Was gaped upon Alice's cock. Mary shuddered, reaching a hand down to massage her own belly, to try and bring more pleasure to the cock lodged deep within herself. Enjoying the overwhelming sensation.
Mary had a boyfriend once? Didn't she?
She couldn't remember him now. And even if she did remember at least the absence of a boyfriend, she knew that no man could compare to what her sister Alice did to her.
On a daily basis.
Or... when Mary had her way, an hourly basis.
Mary often got her way.
Sometimes she just had to show up for Alice to get overwhelmed with lust. Sometimes all it took was a touch. A suggestion of anything more.
And Alice eagerly returned any such suggestion. Now that Mary had been split open upon Alice's cock, Alice could finally begin to fuck. Taking her older sister with full thrusts. Slipping her cock free from Mary's womb. Nearly free entirely, before bearing down once more. Before splitting Mary open once more.
At any moment, it was as if a full 20% of Mary's body was her sister's cockflesh. And delivered with inhuman strength. With terrible speed. And with a stamina that was slow to tire. Once Alice got started, it was all that Mary could do to endure.
Endure and bide her time.
Alice kept thrusting. Fucking Mary through another half dozen orgasms. Starting to swell Mary's belly around precum alone. But she kept going.
Until she reached her second orgasm. Until she thrust. Until she pushed her hips so hard that she heard the entire barn start to creak. Until she heard the splintering of wood. But that didn't stop her movement. It didn't stop her orgasm.
It didn't stop her cum from flooding through her sister's womb. Bloating it out. Stretching Mary beyond any reasonable limit. Enough that it could only be assumed that Mary was thoroughly pregnant. And yet, Mary hadn't been knocked up yet.
Alice hadn’t filled her sister with legion of unholy spawn.
She hadn’t managed a single spawn in any of her couplings. Her ambitions limited. Not dreaming of empire, or even legacy, she dreamed only of this strange moment. The act of filling her sister.
Never the aftermath of what that could achieve.
Always sowing. Never reaping.
Mary always filled, but never pregnant.
Always eager to seduce her sister.
Alice might have wondered about the strangeness of it all. She might have tried to remember a time before. Before she fucked her sister. Before she was over eight feet tall.
Before horns curved out from her head.
There must have been a time before?
Right?
But such wondering didn’t linger.
The roof collapsed.
Support beams and roofing crashing down on top of them.
Enough to kill lesser women, to bury and ruin anyone not so prophetically cursed. Enough to make at least most people pause.
The barn had already been weakened from last time. And the time before.
And as Alice fucked Mary through a wall, the supporting structure failed to hold.
Enough ruin and destruction to slow Alice down.
To leave her dazed. To leave her exposed.
“Shit! Mom and Dad are going to be so pissed!” Alice tried her best to be a good daughter. She tried not to fuck buildings into ruin. She tried her best. Mary didn’t. Mary encouraged Alice to be her worst.
Her advisor. Her tempter. That devil pushing doom along its next steps.
Though, as wicked advisors, Mary wasn’t the most effective. She seldom seduced Alice to anything beyond lustful display.
Display.
The minotaurs had survived the collapse of the barn.
Some with bruises. But thick skulls and full horns had saved them from the worst of it. The cowgirls took their time to slowly pull themselves from the rubble. To turn and watch Alice and Mary.
“You know... maybe we should stop.” Alice suggested. Guilt and responsibility showing themselves at last. She had reached two orgasms now. That was probably enough. It was time at last to face consequences. To clean up her messes, to check and make sure the cows are okay.
“You don’t want that.” Mary told her. Mary was right.
“You want to keep going.” Mary continued.
Alice didn’t deny.
"You haven't even fucked my ass yet." Mary shook her head.
"No... I haven't."
"It would be a shame to leave the task unfinished. To leave your older sister unsatisfied."
"That would be kinda mean, yeah."
"But you are tired, aren't you? You did such a good job fucking me." Mary soothed, pushing back against Alice. More a suggestion than an actual shove.
But a suggestion enough to send Alice sprawling back. For the Dark Lord herself to lay there in the rubble. On her back. Cock still uncomfortably rigid. Still thoroughly lodged inside of Mary.
"Yeah... I like fucking you so very full."
"I know dear. You fuck me like nobody else." Mary praised. "But you don't need to do all the work."
"I don't?"
"You don't." It was like a game between the two of them. Alice was so often filled with lust. Maddening lust that drove her hips. That drove her to terrible action. To thoroughness, to fuck sessions that ended in ruined wombs and broken buildings.
But how much of that was Alice and how much of that was the Dark Lord? Sometimes, Alice just wanted to lay back. "Just lay back." Mary told her. Alice didn't resist.
Sometimes Alice just wanted to be cared for. "Let me take care of you." Mary slowly turned herself around. Crawling and rotating, make sure to never let that cock leave her body. Turning to face her sister.
To mount the Dark Lord’s throne.
Even filled with seed, even rounded out past atrocity, Mary showed surprising agility. Perhaps even stamina beyond the Dark Lord's own. As after a few moments, she started to raise her hips. She started to ride. Moving up and down. Pleasing her sister further.
Pressing her hands down on Alice's heavy chest. Kneading her sister's breasts. "You are such a good sister. You take such good care of me." Mary whispered. "But sometimes you have to surrender. And let me take care of you."
Brushing her fingers across one of Alice's nipples. The two women titans now. Beyond any human form. Dwarfing even the minotaurs they kept. The minotaurs now watching. Yet even as Mary was lesser than Alice in every way, she still knew enough, she still cared enough to know how her sister really wanted to be treated.
That for all that vim, after Alice had shot her load. Alice loved to be controlled. To be held. To be told what a good girl she was. "What a good girl you are." And perhaps that was the magic to this. That restraint holding Alice back.
Alice could conquer all that she surveyed. She could claim her every desire. And she had. But what she desired more than thrones. More than slave harems. Was for her sister to slowly ride her cock. For her sister to hold her down.
For her sister to whisper. "What a good girl you are." And that whisper, that idea. A good girl. Enough to make even a Dark Lord pause. To make even that terrible masculine destiny whimper.
To make a dark lord's cock flutter.
Alice laid there beneath Mary.
Her terrible cock pushing through Mary's womb.
Breaking through cervix.
Training her sister's flesh.
But was that cock truly a conqueror? Was it a pillager?
When it was invited?
When it was cherished?
When it was trapped?
Stuck there in her sister's womb.
Slowly milked once more.
Alice looked up. Her body awash in sensation. Her mind tumbling from the same. Feeling the expert touch along her nipples. Feeling the way the full of Mary's body catered to her. The trained muscular squeezes upon every inch of soulbreaking shaft.
What need now did Alice have of empire?
What more could she desire but this?
To lay back.
To be ridden.
To be caressed.
To be her sister's good girl.
"Almost there. Let your older sister take care of you." Mary cooed.
"But... what about the barn?" Alice asked with some fear.
"A later problem. We will deal with mom and dad together."
Alice nodded. Fear soothed by word and womb.
"But first you have tasks and chores undone." Mary warned her.
"What? You expect me to finish milking now?" The pails had been knocked over and collapsed in the barn's ruin. What milk Alice had acquired was now soaking into already cum soaked ground.
"If we have to, I'll milk your cock until every vat is filled." Mary threatened.
"Again? But won't they notice?"
"They didn't last time." Or the time before. While Alice's ambitions had stalled, her corruptive nature hadn't. Her seed, her scent, her lust warping people further. Into monsters. Into useful things.
How many would drink her seed?
Not unknowingly.
But without complaint.
"It will be fine. You are nearly there." Mary soothed her. And Mary started to move her hips faster now. "Give your sister one last orgasm. And then... and only then can you fuck my ass."
That thought, that temptation beyond any other got Alice going again. Got her pumping her own hips from below. Bouncing her older sister with each full thrust. With each hop. With each slam of cock against back of womb. Fucking Mary every so deep.
Mary's body warped to become her sister's sheath.
What had they been before?
Not this.
Once, some months ago, Alice didn't even have a cock.
Yet there was still some part of her. Still some desire bound to Mary's words. Bound to Mary's gaze.
Alice would give up the world to rise in her sister's esteem.
And in many ways she had.
Did Mary sense it?
That possibility? That chance to turn everything around? To bring the rising dark lord to ruin? Or even claim the mantle for herself? A crown so loosely held that it could be seized?
Had Mary wished it, would she have taken her sister's cock away? Broken Alice upon that shaft? Turned her adorable younger sister into her own concubine bride?
Had Mary wished it, it would have been so.
But Mary wished for it not.
There was love there.
Affection. Twisted as it was by lustful demand and corruption's excess. Mary wanted her sister to be happy. Mary wanted her sister to flourish. But not to the expectation of parents.
Not to the expectation of the tri-counties.
But instead, to an inner contentment.
Currently, inner contentment dwelled within Mary's womb.
Mary ran a hand along her cum bloated belly. So much fluid churned by Alice's every thrust. Her hand pushing into the pudge. She was filled so thickly that she couldn't reach deep enough to feel the outline of Alice's cock any longer.
But each push against her belly was not in isolation. It pushed the seed inside. It made so many waves. So many ripples in the pond. And Alice felt every ripple. Every twist. Every clench of muscle. Every bit of lust.
And it was too much for her. Too much to resist. Too much to not give in. To cry out, and let loose her seed once more. Far too much for any woman to recieve. Not even Mary.
And now Mary was already full of the last load. And even as the world itself warped around Alice's desire. There were limits. Only so many times over a space could fold. And so as that orgasm surged, as the flood of seed rose high.
Mary was pushed higher. The seed enough to raise even her augmented form. Slowly now, rising the sister. Shooting her off of that cock. Pouring seed out like a profane fountain.
Like a firetruck.
Blasting and lifting Mary up. Until Mary was shot off of Alice's cock entirely. Until the next spurt splattered across and painted the full of Mary's body.
Until Alice's cock slipped free. Slipping up towards the sky. The fountain shooting up and over them. Cum raining down. Hungry cowgirls gladly drinking it from puddles.
Mary herself draining now. Seed pouring out from her cratered pussy. Enough to nearly drown her sister below. If the barn were still intact, there might have been a danger of flooding. Yet as it was, the walls were broken, and the seed spread. Flowing through ruin and seeping into open field.
And still Alice was rigid.
And still she craved more.
What her ambition demanded.
What her sister promised in whispers.
Mary raised herself up. Standing to her full height. Much of her mobility restored with being so drained. Standing on wobbly legs. And then starting to bend them.
To lower herself down. To perch herself above that terrible cock. And slowly, slide it between her asscheeks. Mary had once been Alice's dream girl. That pinnacle of sexuality. That twisted admiration of older sister.
But that vision was limited by the possible.
By the likely. By the normal restraints of excess, propriety, and conventional dimensions.
Yet those limits had slipped.
Warping Mary into a giant.
Taller than nearly every woman who had ever lived.
With hips that shattered door frames, and hid the strength of leg and glute to shatter even metal and bone.
With breasts that stretched at every top and dress that tried to contain them. Full things. Not perky. Full of too much mass. Too much heft for gravity to entirely ignore. But thick enough to form a foundation of mass, like grand pyramids rising up from her chest.
Pyramids of a much more pleasing shape.
That wobbled and shifted with each movement. That did not wiggle, but moved as a glacial mass. Perhaps in time, perhaps in the full of ruinous desire, they would crush as even the glaciers once did.
Rending valleys in the earth as they were dragged along by inhuman forces.
Forces like Alice.
Yet for now, Alice was behaved. Restrained. Obedient. Laying back very still. Waiting for Mary to take part. Waiting for Mary to descend. While Mary had been altered, while Mary had been sculpted by Alice's desire.
While she had been created as the answer to her sister's needs. While Mary was the only one who could truly endure Alice's lust...
Endurance was not easy.
And to be fucked by a dark lord was one thing.
To be sodomized by one? Another still.
And yet Mary slowly lowered herself down.
She felt her ass start to stretch upon that glans. That ring of wrinkled muscle. It had endured such before. It had stretched to take that terror before.
And it would again.
And yet it stretched so slowly.
Relaxed so slowly.
Opened so pitifully.
Each movement threatening to sunder it outright.
And it might well be sundered by the time Mary was done sating herself on her sister's cock. Mary didn't care. She would give anything for her sister. Her flesh. Her destruction. Her lust.
And so she gave. Pressing herself down. Forcing herself open, stretching herself open upon that terrible cock. Even breaking herself. Going beyond the limits of even her corrupted flesh.
But not too far.
Mary was exceptional. She could take that full terror in her ass without breaking entirely. It hurt. It burned. But even such a flame did not compare to her own incestual lusts.
Her need to please Alice.
Her need to provide for her younger sister.
Sometimes younger sisters needed sage advice.
Sometimes they needed brutal sodomy.
Mary was eager to provide both. And with a push of her powerful legs, she descended. Pushing that column of fuck flesh deeper inside. Boring through her. Punching through another sphincter in moments, and then sinking deeper still.
Mary's guts clinging to that scepter.
Her innards twisting about that fuck flesh. Feeling that impossible pressure. Feeling the way her body warped to accommodate Alice. Beyond even what pressure and mass alone could push.
Mary's body bent. Space folded. Organs compressed and shifted about, all to make the pleasure a bit more exquisite. To let Mary bring her body crashing down.
The avalanche impaled upon a spire.
Pushing herself down, taking nearly the full of Alice's cock deep inside her. Taking that cock so deep that it pushed up past her ribs. So that every eager breath was a caress.
Every thump of Mary's heart was a vibration along Alice's shaft. And how eagerly Mary drummed. If this was the first coupling of the afternoon, Alice might have taken control.
She might have been so driven by lust that she could have fucked Mary to near annihilation. To the point that Mary couldn't walk for a week. Again. To the point that only Alice's corruptive magic could have healed her sister. Again.
But Mary knew her sister's lust well. She knew her sister's stamina. She knew better than to invite anal first thing. She had to build Alice up to it. She had to wear Alice down. Get her nice and tired. Get that initial lust out.
To fuck enough to reduce Alice to a pliable little puppy.
A puppy with a cock that could dethrone gods.
But a puppy all the same.
"Good girl." Mary gargled. Each whispered word a lung's feather caress. An incitement to more. A reward. A pointed application of lust and control.
Enough to leave the Dark One whimpering.
"Just lay back." A caress of chorus. As Mary, now fully sheathed, started to move herself once more. To fuck her body upon the full of Alice's terrible cock.
"Such a good puppy."
Mary whispered. With too much intentionality. Mary wasn't entirely a fool. She wasn't entirely blind. Her memory wasn't entirely excised. Even if Mary didn't remember exactly what came before, she knew this much:
She hadn't always fucked her sister Alice.
Alice hadn't always had a cock.
The cows hadn't always been glutton's for Alice's cum.
Her old clothing was now far too small.
Either her clothes had shrunk.
Or she had transformed.
And all thoughts and possibility swirled around Alice.
Everything that mattered was tied to Alice.
And from there, Mary could only assume...
Everything was Alice's fault.
If Mary had been upset once, such anger had been burned from her. She was not unhappy being her little sister's cocksheath. But such desire, such compulsion, it had not robbed her of agency entire.
While she couldn't help but submit to Alice's every desire...?
That didn't mean Mary was absent of her own.
"Bark for me puppy."
Mary demanded.
Alice looked up at her confused. "What?"
Mary raised herself up, halfway off that cock, and then stopped. Resting there. Waiting.
"Bark." Mary repeated.
Alice, increasingly frustrated, tried to buck her hips up from below. But in such a position she could only manage a few inches.
And so Alice whined.
And then she barked.
Just like Mary demanded.
"Good puppy." Mary praised. The words sinking into her impressionable sister below. As submission was rewarded with sex. With eager fucking.
With pleasure.
With Mary's ass.
Mary slowly fanning the flames of the Dark Lord's submission.
Making it worse over the past five weeks.
"You know what every good puppy has?" Mary asked, testing the limits, seeing how far she could push her sister's apparent powers.
"What?"
"A knot." Mary demanded. "Knot me Alice." And then she pushed down again. Sheathing herself upon Alice's cock. Pushing and pushing deeper, grinding herself against that base.
Against that growing girth.
Pushing Alice over the edge. Into another terrible orgasm. Into another expression of a Dark Lord's desire. Reality itself warping around what Alice wanted.
Even if it wasn't her desire originally.
Alice's own flesh warping. To grow thicker still. To pour her seed out, stretch her cock out inside her elder sister.
To tie the two in place.
Even as the cum surged through Mary's body.
Filling not Mary's womb, gut now Mary's guts. Her stomach. Her throat. Enough seed that it shot right through Mary. Alice using the full of her sister as her sleeve. As her fountain.
And locking the two of them into place.
For hours. All by a Dark Lord's will.
All by an elder sister's demands.
As the two became tied in place...
As Mary focused a Dark Lord's lust entirely on herself...
The old adage was once again proven true.
Evil always plants the seed of its own defeat.
