Horseplay

Gabriella tried to change herself back into a boy, but failed on every attempt. Ultimately, she realized that she enjoyed her feminine features and she still had a cock, so it was the best of both worlds. Knowing how early it was, she trekked outside wearing nothing at all. Enjoying the cool breeze before the sun crested the horizon. She relieved herself on a tree in a secluded area of their estate. She turned to see Chantal walking toward her in the pre-dawn light, her heavy breasts bouncing with each step and her larger cock swaying betwixt her legs. Their mother had endowed them with bigger cocks, but Chantal’s was a fair amount larger.

“Isn’t it too early for the princess?”

Chantal spoke a phrase and waved her arms. The tree branches reached forward and pulled Gabriella closer, causing her to be ensnared by many small vines and branches. Once the spell resolved, Gabriella was forcefully enveloped in the side of the tree, her ass ripe for the taking.

“What the hell are you doing!?”
Chantal laughed as she struggled. “I have to relieve myself too. So, I came to the nearest chamber pot.” The buxom girl used her soft hands to spread her sister’s rump. She moistened her shaft before pressing it into her backdoor. Chantal eased herself all the way in and with some effort, began emptying her bladder.

Gabriella shrieked and struggled, halfway encased in the tree. Her cock grew hard as it rubbed gently against the bark. Chantal dismissed her pain, continuing to relieve herself. She had plenty of fluids stored for this moment, some of which remaining from their spells the previous night. The flow continued as she reached around and patted her sister’s firm belly.

“Thanks for holding this for me.” Chantal giggled as she continued blasting water into her sister’s ass.
“Aren’t you almost done?”
“Just about. I used a spell that makes the water in me take up less space until it exits, so I can hold twice as much. It’s really handy for those long studying sessions.”

Gabriella endured as her belly inflated against the tree. She could do nothing helpful without free hands to make the magical gestures. It lasted a while longer before she could feel the stream slowing.
Pulling back, Chantal pressed all the way in, causing a shriek from her unprepared sister. “What’s wrong, not ready for all this meat?”
“Take it out!”
“Hell no. You just have to get used to it and it will feel great!” She stayed in place, buried in the fair-skinned butt. “Don’t let any out or I will turn it into a solid inside of you!”
“It’s too much, please stop!”
“Are you begging? That makes this even hotter.” Chantal drew back and pressed in with all her might. Forcing the girl’s belly and cock against the tree. Her ass flattened against Chantal’s hips, hiding her cock entirely in her ass. She drew back and pushed in again, equally as hard.

“No, stop, I can’t…” Gabriella gasped, shooting her seed upon the tree and into the grass below her.
“Done already? Typical. Guess I can go for the quick finish then.” Chantal set her legs apart and pounded her restrained sister. She felt the liquid inside sloshing and churning with each stroke.

Gabriella whined as her belly squished against the tree and her sister’s cock plugged up her ass. “Damn you! Hurry up and cum!”
“Want me to cum in your ass? Want me to fill you even more?”
There was a long hesitation. “I don’t care.”
Chantal pushed balls deep again and stopped, just barely holding back. “You really want me to cum in your ass?”
“Just do it. Just cum in my ass.”
The words excited Chantal more than she imagined. Without moving she emptied into her already burdened sister, both girls moaning as she did. They waited, both breathing heavily, until the hung woman fell limply from Gabriella’s ass.

“That was fun.” Chantal said a spell and watched as the tree slowly released her big bellied sister. She couldn’t help laughing as she watched her stumble around the tree and begin emptying. They walked back in silence, still alone due to the early hour. Nearing the back entrance, Gabriella stopped and started casting.

Before she could react, Chantal’s hands were bound tightly behind her by a magical rope, wrist to elbow. “Stop this, we’ll get caught! At least get us inside!”

“That didn’t stop you from pissing in me, did it sis?”
“Nobody saw us, but this is right outside!”
“Yeah, you better keep quiet, whore.”

Gabriella took a long time to cast the next spell, weaving imaginary runes in the air and speaking the mystic tongue. With a poof and a mystic haze there was a large black stallion standing beside them.

“What the hell are you doing?”
“This is your new fuck buddy!” Gabriella smirked.

The horse’s black fur shined in the peeking sunlight. It inspected her, sniffing the bound, naked woman as it walked closer. The large animal’s shaft grew beneath its legs. It snorted, tilting its head as a nudged her shoulder. Gabriella stroked the horse’s mane.

“Are you ready to take a horse cock?”
“I’m not going to let you do this.”
Gabriella cast another spell. Chantal gagged as a white blob appeared over her mouth. “Doesn’t look like you have much of a choice.” She tried to run, but again, Gabriella cast a spell and watched her sister stumble against a waist high stone wall. Her legs were spread apart by a conjured bar strapped between her ankles. “You look like you’re completely fucked now, dear sister.”

The beast trotted closer, sniffing between her legs. Gabriella crouched and moved beneath the beast, holding the huge cock as she tried to place the tip in her mouth. It barely fit, and after struggling for a while she decided to use a magical aide. She made a gesture and tried again. This time the tip spread her mouth wide and started moving deeper into her windpipe. She maneuvered her head, allowing more of the thick shaft to work its way past her tonsils. Suddenly she felt the animal draw back and tense. Within an instant, it thrust forward, forcing a large portion of its meat down her throat.

Gabriella grabbed her throat, feeling the warm organ beneath her skin as it was pulled up and pressed down again. This time she felt it in her chest. She frantically slapped the horse, trying to halt it, but the beast was wild with lust. It continued force-feeding her its cock as it worked itself into a frenzy. Luckily Gabriella moved aside before it finished. The organ flopped into the air as it thrust wildly, trying to find release. She directed the massive animal to her subdued sister.

The horse raised itself high and put its front hooves on the stones as it edged closer. As it moved near, it thrust wildly into the air, anticipating entrance. Chantal gave muffled screams as she also anticipated the impending entry. The wet organ slid atop her ass, lying upon her back momentarily, Gabriella could see her sister was in for quite a large treat. The horse lowered the shaft slowly, attempting to ease the tip into the warmth beneath her legs.

Gabriella walked in front of her sister, stroking her hair as she passed. “Here it comes.”

The horse grunted as it pushed cautiously, trying not to slip past again. Chantal’s asshole spread unnaturally wide, her magical body accepting the enormous head of the cock. The horse knew it was in, and it thrust in with immense force. The thick, damp pole half disappeared into her as she screeched loudly. The horse ignored her high-pitched wailing as it focused on fitting its massive cock into the tight, wet nook.

It dominated the poor girl, slamming into her without hesitation. Chantal seemed to be in less pain as time went on, each thrust pressing her belly outward, showing an outline of the horse cock inside her. The beast had surprising endurance, continuing for a few minutes at a speedy pace. It snorted and put all of its weight into the pummeling. Chantal squealed and the animal whinnied. It reared back and lifted her up enough to show her belly distend, filling with blasts of the conjured horse’s sperm. It grew heavy, hanging low as the flow eventually stopped. The weight of the massive amount of sperm pulled her swollen stomach downward. The beast lowered her as it finished, balancing her over the wall, her stomach puffed out like a ball.

The horse edged back. The unwieldy cock popped free, allowing some of the sperm to pour onto the ground. For some reason Chantal fought to hold the rest in, awkwardly using a few fingers to keep her gaping asshole plugged. Gabriella nearly questioned it until she turned to see two robed women standing in the doorway.

A woman with uncaring eyes watched from beside their mother. Their aunt, a member of the local council, had come early. Mabel stood taller than Magdalene. Mabel’s caramel hair and deep brown eyes complimented her tanned complexion. Her resting expression was austere, bordering on irritable. Her manicured eyebrows always seemed to imply she was judging you. She was prettier and had a more formed body than their mother, but the robes they wore kept that hidden.

Gabriella removed all of the magical bindings from her sister. Now free, Chantal scowled as she leaned upon the stone, still retaining the massive amount of sperm without her hands. Both girls were silent as they waited for chiding from their mother.

“They remind me of someone.” Mabel spoke, stone faced.
“Yeah, they do.” Magdalene shot a malicious stare to her sister.
“I recall someone being jealous of my abilities, so she summoned a pack of wolves to assault me.”
“That was years ago, Mabel, can’t you let it go?”
“I only wish I had summoned a horse to fuck you like your… daughter did.” The expressionless woman took care to refer to Gabriella’s new gender. “She is quite resourceful, putting your actual daughter to shame.”

As usual, their aunt had gotten under their mother’s skin. Magdalene narrowed her eyes and set her jaw, furious. She turned to her daughters and spoke mystical terms as she gestured. “I told you two to behave and you ignored me! Now I will have to punish you yet again!”

Chantal yelped, jumping upright as if something had entered her backdoor. “Mom, why?”
“Your punishment is to hold all of that in while you watch your sister.”

Gabriella couldn’t stifle her laugh as her inflated sister clenched her teeth, stiffly walking in a circle. Her humor faded quickly as something approached. The stallion from before had come back with a larger cock and balls that were double the size. “No, please. She started it.” She said with sorrow.

“I don’t care, I’m ending it. What if the other council members had come early?”
“But, please…”
“No! Bend down and don’t make me bind you!”

Gabriella knew it was pointless to argue. She leaned upon the wall as her sister had before. “Can I at least get it wet first?”
“That is what your sister is for.”
Chantal was distressed, but she was still defiant enough to roll her eyes as she bent down to put her mouth upon the massive shaft. She wasn’t able to get her lips around it, so she licked the flared edges of the head as best she could. Her full belly gurgling as it hanged below. She spent a minute licking the edges of the cock before moving to her sister’s ass. She licked her fingers and used them to prime the unhappy girl’s ass.

Magdalene waved her aside and whistled to the horse. The beast carefully pressed against the still tight hole, but slipped away. It took three more failed attempts before it finally parted her. Gabriella screamed louder than her sister had. Stepping forward as the huge tip threatened to split her apart. Her hips were against the stone as the beast continued the pressure. It startled her as the end finally breached her. Gabriella balled her fists as she hung over the wall, yelling as she tried to cope with the pain. The beast seemed more relaxed than before, pausing to allow her recovery time before it moved again.

It snorted and took a step forward with its hind legs, forcing the unreasonably sized cock deeper into her bowels. Detesting, Gabriella struggled to find a better angle to accept the unplanned entrance. She turned and raised her hips before realizing there was no better option. She relaxed and breathed deeply as the beast hesitated. The huge horse rammed in, again causing Gabriella’s semi-erect cock to pulse, sending streams of cum onto the side of the stone wall she was pressed against. Gabriella’s pained expression relaxed as she blinked repeatedly. Her entire body slacked, as she seemed to be in shock.

The stallion continued, pumping the limp girl upon the wall until it made a triumphant sound and blasted her full of cum. Gabriella’s belly bulged, distending with an absurd amount of cum. The beast stepped aside and removed its massive plug from her ass. Gabriella was pulled backward by the flared tip of its cock as it was pulled free. She fell onto her back, gripping her swollen belly as the horse vanished in wisps of black smoke. With her senses returned, she gave a pleading look to their aunt.

Chantal leaned upon the wall, giving a drained smile as she watched her sister in agony upon the ground. “You are just a regular cum dump, aren’t you?”
“Shut up!” Gabriella writhed. “I should have summoned an elephant instead, you whore!”

“Enough!” Magdalene boomed. “Go empty yourselves and we shall have a nice dinner to welcome your aunt Mabel.”

Chantal jumped, tensing with the sudden removal of the magical plug in her backside. Both of the girls waddled into the woods in opposite directions. Their somewhat erect cocks slapped their legs as the held their full bellies. Gabriella moved slower, as she held nearly double the amount of her sister.

Later, the four of them ate in silence. They all acted as if nothing had happened, until Mabel grinned wickedly. “Remember that time you gave me a horsecock, sister?”
“Mabel, we shall not speak of such lewd behavior during dinner.”
The woman sighed. “Your mother was just as frisky as you two, I must admit. Kind of a prude, though. Always tried to hide her desires.”
“Mabel, I won’t say it again.” Magdalene rose in her seat.
There was a short silence. “Later I will have to tell you what she enjoys for desert.” A smug grin spread across Mabel’s face. The rest of the dinner was tense to say the least.

One Sided

Their mother had returned the following day to find Gabriella on top of Chantal, both of them asleep. The magically erect cock still inside Gabriella’s pussy, Magdalene could not resist her own carnal pleasures, but she could hide them under the guise of punishment. She disrobed and spit upon her own cock, which she had decided to keep since their last encounter. I have enough children to deal with. I’m going to keep this cock, I think – much less maintenance. After spreading the wetness upon her shaft, she stepped behind the couple and parted Gabriella’s firm ass. She pressed the tip in with ease.

Gabriella’s head shot up as she tried to pull away from the intruder. Magdalene held her hips as she pressed the shaft into her unwilling girl. Chantal awoke beneath them, frightened, but her expression quickly changed to lust as she pressed her shaft deeper into her sister, whom was still straddling her. With her arms still missing, Chantal could only press her hips up. She was able to penetrate almost fully, as their mother held her screaming daughter in place.

Gabriella gasped, quieting as she now felt the still foreign sensation of pleasure from her new pussy, which gripped the cock in her front while she endured the discomfort from the back. She was finally able to press back, taking them both in fully as Magdalene continued to painfully skewer her.  They found a rhythm as Magdalene reached forward to grab her daughter’s breasts.  Gabriella enjoyed the sensation, using her mother’s touch to achieve climax. Her mouth quivered as she took the cocks, which plunged in and out of her. It was overwhelming her after a moment; she tried to move away, but her mother lifted her by the chest and continued to rail her.

“It’s too much!”
“A proper lady shows little emotion.” Magdalene pressed deep, holding her in place as she spoke. “You will learn humility, Gabriella.”

Chantal watched from below as their mother grunted lightly, setting her jaw as she filled her daughter. Gabriella’s stomach moved outward with pulses of seed. It pressed her skin out before it settled in her belly. The tight warmth still felt amazing upon her shaft, as Chantal railed her sister. Each thrust caused them both to moan and after a short time, they completed together. Gabriella’ gasped with delight as cum shot into her pussy, filling her even more.

Their stone-faced mother stepped back, allowing her thick cock to slap against her leg. Gabriella rolled onto her back, beside her sister. “Chantal had her fun. Now it is your turn.” She made an unknown hand gesture. “I think you should keep the feminine form, it suits you, Gabriella.” She completed the spell she had been casting.

“What the hell is that supposed to-“She stopped suddenly as she felt a change happening below. She watched as a lump of skin swelled beyond her small bush, elongating into a full-fledged penis again. She smiled as she touched it. “Thanks Mom!” She paused, thinking, “Wait, what happened to all that seed that was in my front?”

She stared blankly, “You will absorb it. I am leaving your other features, but I will give you one more boon.” Her fingers danced in the air as she spoke a phrase. Gabriella’s cock grew, swelling past the length and girth of Magdalene’s. Gabriella stood, allowing it to hang awkwardly between her legs as it increased in size. It dangled just above her knees and it was mostly rigid. Her balls grew as well, hanging lower with seed.

During the increasing of her size, Chantal’s cock shrank and receded in kind. Once stopped, it looked average at best. It also went limp for the first time. “Why take mine away, Mother?”

“I just transferred it. Again, you had your fun, now it is his… her turn. As you notice, your organ doesn’t get hard now. Good luck finishing like that.” Her mouth turned up in a tiny smirk as she made another sharp gesture. Chantal’s tits grew larger. They sagged with their new weight, but retained their perkiness. “You two get all of these urges out of your system before the council arrives in the next few days.”

“At least give me my arms back!” Chantal demanded. Her mother ignored her as she headed out the door.

The areas below her shoulders were still smooth and her posterior still unnaturally large. Chantal’s breasts had been on the larger scale to begin with, but now they nearly matched her sister’s enormous chest. Chantal rolled her eyes, realizing that she looked like every man’s wet dream.

“She always favors me, Chantal.” Gabriella spoke condescendingly as she stood above her modified sister. Her face retained some of her boyish features, but they had modified just enough to fit with her feminine body. Her reddish brown hair went just below her shoulders. Her pinchable cheeks dimpled as she smiled. Her green eyes narrowed with wicked thoughts. “I’m going to make you squirm.” She put a hand on her modest belly. “After I empty.” She stepped into the opposite room.

Chantal spouted off a few mystical phrases.

Gabriella screamed and rushed back into the bedroom. Her belly had expanded and now she appeared heavily pregnant. Holding an empty chamber pot, she growled, “What did you do to me?”
“Oh relax, it’s just our piss.” Chantal gave an overly dramatic shrug, rolling her eyes. “I also may have turned it solid in you.”
“You emptied the pot into my ass and turned it into stone?!”
“You should have emptied the pot earlier when I said it was full!” Chantal smiled wickedly.
“Get it out of me now!”
“I can’t, I need my hands for that spell. Besides, you always have a stick up your ass, so you should be used to it!”

Gabriella gave a venomous glare. “Well, looks like I’ll have to make you regret it.” She made a gesture as she cast a spell.

There was a moment of silence before Chantal noticed something in her belly. Suddenly she felt a rumbling as small things filled her. She felt a countless number of small objects pouring into her. She flailed her legs in panic as the weight increased. She rolled over and watched her stomach growing beneath her. It grew, bumpy and weighted as it rested upon the bed.

Gabriella spoke another word and the sensation halted. “I put something solid in you too, dear Sister. Well, some things that are solid.”
“What is it? They’re so heavy!”
“I put gravel in you.” Gabriella giggled. “You know, to keep you in your place.”
“You dirty mother-“
“Ah, don’t talk about our mother. She’s not here to help you.”

Chantal struggled, but was unable to lift her weighted belly. “Damn it, remove these right now!”
“So, I gather from your frustration that you don’t know any other spells to cast without your hands. Looks like I can have my way with you then!” Gabriella lifted her massive cock and slapped it onto her sister’s back.

The warmth and the length astounded Chantal. “You can’t be serious.”
“Just because you can’t get hard doesn’t mean I shouldn’t enjoy this! Besides, you were more anal than I ever was.”
“Fuck you!”
“Oooh, little sister has teeth.” Gabriella held her cock as she conjured a generous amount of lubricant upon it. “I don’t think you’re in a position to stop me. So, yeah, I think I will!” She pressed her wet shaft in between her sister’s wide posterior. It went in easily, parting her on the first attempt. It felt amazing as Chantal wiggled her butt in a fruitless attempt to get away. She struggled and whimpered as the enormous shaft pressed halfway into her ass.

“Enjoying this, dear Sister?”
“Stop now and I won’t hold a grudge.”
“I know you better. Plus, it feels too good to stop now!” Gabriella pushed farther until it stopped. There was still a couple of inches left. She could feel the rocks, but this place felt softer. “Just a little lower and…” She felt a pop as Chantal howled. “There we go!” She pressed deeper. “All in!”

Chantal’s limp cock slapped between her legs. Her frustration was indescribable. It would have allowed her to cope with the pain, but instead she had to endure without orgasm. “Hurry up!”

“Nah, I think I’ll make this last. I’ll draw it out for you.” She withdrew the cock before plowing it back in. But, in truth, Gabriella was feeling her own orgasm building. “She pushed as deep as she could and stopped, flattening her sister’s wide behind against her hips. Chantal groaned as she tried to pull away, rolling forward on her belly, burying her face in the sheets. Her head pressed against her shoulders at an awkward angle. Gabriella loved her whining. She pulled back and pressed in again, hearing her sister scream into the covers. She continued a few more times, watching that glorious ass shaking, until she had to stop once more. Again, she was fully inside as she waited. She held her sister’s hips and moved her so her face was no longer mashed, allowing her to penetrate slightly deeper.

“Ahh.” Chantal let out a low groan and tensed as she rose. This pushed Gabriella over the edge.
“Damn it.” Gabriella grumbled as she fucked her sister without regard. Chantal whined and complained as she plowed her.
Chantal felt seed blasting into her ass. She yelped, saying an unknown phrase under her breath. Suddenly the pulses of fluid stopped and Gabriella was the one yelping. “What did you do? It’s like it stopped in my cock!”

Chantal clenched her fists and wailed as she felt the cock grow wider in her ass. The feeling was too much, and in spite of her limp cock, she too shot her seed onto the side of the bed. Streams of the fluid hit the sheets and the floor. Her former brother did not know what was happening and he demanded an answer.

“I-I turned it into an adhesive.” She gasped, barely able to speak.
“Why would you do that?!” Gabriella frantically tried to pull away, but they were locked together.
Every tug caused Chantal to follow. Her ass was painfully full now that the forced orgasm had passed. Her hefty breasts shook as she was jerked back and forth, her butt wobbling as well. “I don’t know! It’s the only other spell I could cast without hands. I had to stop it!”

Gabriella’s breasts rested upon her burdensome belly, which rested upon Chantal’s meaty rump. “I can’t cum any more, it’s all stuck in my cock!”

“I know, I feel it. It’s so thick now!” She huffed. “Maybe this will teach you a lesson.”
“What is that? That you are a hysterical woman? I bet that huge cock in your ass doesn’t feel the greatest!”
Chantal scowled over her shoulder. “No. It should teach you not to push a woman too far. We can be dangerous.”

They argued as they struggled, both trying to free themselves, but the bond was too strong. They decided to wait for their mother’s return, as they couldn’t move far due to their weight. They were forced to stay stuck in place. Gabriella was balls deep, resting upon an armless Chantal, whose legs were spread and her belly holding them both up.

Hours passed before Magdalene returned. Their forbidding mother sighed deeply as she stepped into the room. “I shouldn’t be surprised.”

“Chantal was an idiot and stuck us together! Help us! We’ve been like this for hours!”

Magdalene disrobed and stepped behind them. “Not quite yet.” She spread her daughter and pressed into her asshole. The sisters endured with constant complaints. Magdalene couldn’t care less. She thrust her shaft into her helpless daughter, in fully and back out, making sure she felt it entirely. “You two are my children. I expect you will learn from this and keep your petty arguments private when the council arrives.”

“Y-yes, mom!” Chantal grunted beneath the pile. Gabriella mimicked her response.

“I will give you one more day to show me that you can act mature.” Magdalene pushed in and shimmied back and forth, working her massive cock as far as she could. She moved in and out, her children moaning with anguish. She leaned forward over them, pressing in with quick, deep pumps. She could feel something hard inside, but she was already so close. It took less than a minute before she filled Gabriella’s rump with her thick seed.

Gabriella rose as her belly filled farther. “It feels like a hose!” Gabriella’s belly spread outward upon her sister, who was pinned, being pressed deeper into the bedding.

Magdalene stepped back, pleased with her daughter’s slimy privates. Magdalene cast some spells and the sisters felt the changes. Chantal’s arms reformed, while the sticky substance in and out grew cool as it became more like fluid. Both of their bellies shrank and smoothed as they emptied onto the floor and sheets. Their ridiculous curves became normal again. They slowly arose, wet and tired. Chantal still retained large breasts and a plump posterior, but they were back to realistic proportions. Both still had large, limp cocks between their legs.

Gabriella’s curves and feminine appearance remained. “Aren’t you going to change me back?” She questioned dramatically.

“Nope. I think you’re quite attractive as a woman. I left your cocks so you don’t get pregnant with some freakish child. Prove to me that you learned some humility and I will reverse it. But you’re out of luck for now. Tomorrow I will check in to see that you are both acting as proper women should.”

Magdalene walked away knowing how outlandish that request truly was.

Gender Dominance

“I know far more than your fragile female mind could ever handle.” Gabriel spoke with derision.
Chantal was used to her brother’s misogyny, “You blow hard! You could never outwit me when dealing with magic. You just hate that a female can outmatch you, don’t you?”
He paused, “Women can’t grasp the complicated magic at work. That’s why I am a master conjurer and you are a simple alteration mage.”
She would take no more. She raised her hands and spoke a whispered sentence. She grinned as she watched him grab his lower region with a shocked expression. His chest swelled and caused his baggy tunic to become taught. His hair grew just below his shoulders and his face changed subtly. He had become a woman within minutes. He grabbed his bosom, eyes wide.

Chantal grinned, “Gabriella? I think that suits you.”
“What in the world did you do?! How?”
“It would appear you don’t understand how much I can alter.” Chantal yanked her sister’s too-small tunic over her head.
“Change me back this instant.” Gabriella covered her breasts.
“No, I think you need to learn to enjoy being a woman for a while.”
“Change me back NOW!” She stomped her foot before tearing her sister’s thin nightgown in an act of defiance, stripping her nude.
Chantal was angry for a moment. Then she giggled, “No, not until you learn your place.”
“Maybe you should learn your place as well.” Gabriel spoke a phrase. Chantal felt something strange in her stomach – she could see something… moving! She could see the outline of something beneath her skin. She grabbed her trembling belly as the object traced its way, lower and lower, until she felt it trying to get out. She could not resist the pressure against her rectum as it exited. It opened easily as the thick, slimy creature moved down her leg, onto the floor. She knelt down in discomfort, allowing the strange sensation to finish. “A snake! You put a fucking snake in me?” There was a pop as the snake vanished before her eyes.

Her cohort grinned, “Yep, how do you like that, you serpent!”
Chantal was livid. “I’ll show you a fucking snake!” She muttered a phrase and looked down, pleased to see an object growing between her legs. It quickly took form and grew – an erect penis, nearly as large as her small forearm. “Let’s see what you think of being the woman!”

Gabriella’s mouth was wide with shock… until a wry smile spread across her face. “It’s so fucking huge!”

“I knew this is what you’ve always wanted. You were just trapped in a man’s body!” Chantal moved closer, pushing her sister’s shoulder down. Gabriella knelt as instructed and put her lips upon the soft, fresh member. She could only fit a small portion down her throat at first. Chantal pressed farther, causing her to gag and pull away. Chantal held her head in place as she pressed her hips forward as much as possible. Gabriella finally wriggled free and gasped as drool ran down her chest, along her newly-formed breasts.

Chantal lifted, helping her to stand. Unlacing her sister’s pants, she slid them to the ground.
“Did that thing take the place of your pussy?”
“Yep, I haven’t figured out how to have both yet.”
The sisters stumbled to a nearby table. Gabriella sat upon the table’s edge. She licked her finger and reached behind her sibling, finding her way between Chantal’s cheeks, she pressed inside. Chantal moaned softly, sliding her meaty cock upon Gabriella’s belly as she inserted another finger into her ass, followed by another.

“Ugh, I can’t wait. Open up, Sister.” Gabriella removed her fingers and leaned back with an inviting glance. Chantal rubbed her massive penis along Gabriella’s soft mound, hurriedly searching for her new opening. She felt warmth and pressed in slightly; once she knew it was the right spot she thrust forcefully. She shrieked as she felt a shot of sudden pain from her behind. She fell forward, trying to move away from the agonizing discomfort, but it only worsened.

“Fuck yourself, sibling.” Gabriella whispered as she grabbed her sister’s butt, wrapping her legs around her hips, pulling her closer. “How does your ass feel?”
Chantal could only manage a pained moan as she was pulled forward, balls deep in her own ass.
“I didn’t feel like being your play-thing so I made a portal from my entrance to yours.” The mischievous girl relaxed her grasp before pulling her victim closer again. Chantal squeaked at each slight movement, unable to reduce her discomfort. Then she started moving on her own. She leaned forward and began pumping herself through the portal.

“You’re not supposed to enjoy it, you hussy!”
Chantal ignored her sister and moved faster, pulling out before pressing back in to the hilt again and again. She pushed in and paused for a moment, trying to prolong the feeling. Abruptly, she moaned loudly and pumped frantically. She quivered as her seed shot through the portal and into her own ass. Gabriella rolled her eyes as she watch her sister, sweating and panting on top of her. Chantal backed away, her member now hanging limply.

“I thought men were only motivated by the temptation of the flesh, dear sister!”
“In most cases they are… dear sister.”
“Change me back now or things will get worse!” Her eyes narrowed as she sat with her legs still spread.
“Of course not! In fact, I think you should be more womanly!” Chantal waved her hands and watched her sister grasp her chest. Her breasts began growing steadily, weighted by liquid. “You cow!” The mounds of flesh poured beyond Gabriella’s grasp, rolling through her fingers and onto her arms; she gave up, allowing them to hang freely as they inflated; she balled her fists and muttered a spell.

Chantal felt something in her again, although different this time. She could feel some sort of liquid pouring inside of her stomach. “You didn’t!”
Gabriella smiled. “Your spells always seem to backfire.” She reached up and jiggled her massive breasts, which seemed to increase the flow of milk into Chantal’s stomach.
Chantal groaned in discomfort. “Well, it’s a double edged sword, missy!” She grimaced as she pressed against her own belly.
Gabriella’s breasts grew and sagged slightly beyond her grasp as she whined, “Ow, stop!” She pressed her arms against them, trying to press the liquid into her sister.

Chantal growled, regaining enough composure to cast; this spell required concentration and delicate movements. Attempting to ignore her rapidly inflating belly, she made mystical symbols in the air. She was beginning to sweat once she spoke the last phrase. Suddenly, Gabriella’s hands pulled together; skin melding as they folded down. Within moments, they had been completely absorbed into her arms, leaving nothing but smooth, rounded stumps.

“What in the hell did you do?!”
Chantal spoke breathlessly. “I’ve learned a great many things since we last fought!”
“You idiot, now I can’t close the portals! Put them back!”
She paused. “I, uh… I don’t think I can.” Her sister’s irritated, confused glare edged her to continue. “I was upset, I didn’t mean to use it so soon, but you pissed me off! …I don’t know the spell to undo it, yet.” Milk still swelled her belly and her sister’s breasts. “I can stop the milk, however.” She spoke a phrase and the flow stopped. Gabriella’s breasts sagged halfway down her midriff. Chantal’s belly hanged an equal amount down her thighs.

“Why the hell would you cast a spell that you can’t reverse?”
“I told you, I was upset, I wasn’t thinking clearly!”
“You’re just a fucking stupid, hysterical woman!”
Chantal huffed. “And you’re fucking helpless. I know most of your spells require a hand gesture.” She squeezed her sister’s heavy breasts, forgetting that would force milk into her. She chose not to show her discomfort. “Now you’re at my mercy.” Beneath her belly, Chantal’s member remained rigid. “Now we’ll see how you like it in your ass, you bitch!”

Gabriella struggled ungracefully, but without hands, she couldn’t put up much of a fight. Chantal brought her back to the table and bent her over. She licked her fingers before pressing them into her sister’s virgin backside. Once she had been somewhat prepared, Chantal held her down as she poked between her cheeks, searching for the primed opening. Once she hit the mark, she nudged deeper as Gabriella squirmed and whined. “This time you’re going to take it!” She moved in and out, going slightly farther with each thrust. Once she was all the way in, she lifted her milk-filled belly, resting it upon Gabriella’s lower back; she held the opposite side of the table and slammed into her sister relentlessly.

It was tighter than she expected, but she wanted to punish her sister as much as possible. “Don’t fight and this will be over soon enough, bitch.” She emphasized the last term, knowing how her former brother used it on her in a similar fashion. She railed Gabriella relentlessly, feeling the fight leave her. Smiling, Chantal decided to add to her discomfort. She stood and pressed all the way in before she said a few phrases.

Gabriella shrieked and cried as she felt the organ in her ass growing. “No, no, make it stop! Get it out, get it ooout…” She trailed off, sobbing as she slammed her stumps upon the table. It grew immensely tighter around Chantal’s now double-thick cock. She slid it out slightly to inspect its girth – It was roughly the size of her wrist now. She pressed it back in and immediately was overwhelmed with delight. She began shooting her thick seed into her sister’s clenching butt. Her larger size increased the volume of her seed as well. She could feel thick streams erupting into her victim.

She reached down and put a hand on the side of her sister’s slightly swollen belly. “Someone else has a full tummy now.”
“Still not as big as yours, fat ass!”
“Well, we can fix that! Unlike a normal male I can keep going with this thing!” She started again, her belly rocking with her violent thrusts. Gabriella pleaded for her to stop, but she enjoyed it too much. She continued vigorously for a few minutes until she heard the door slam open.

She stopped, turning to see their austere mother standing in the doorway. “Chantal, what in the hell is going on?”
“Gabriel was insulting me so I put him in his place! This is Gabriella.” Chantal smiled as she pressed deeper, causing her now-sister to squeak in discomfort.

Magdalene couldn’t believe what she was seeing. Her former son, now a curvaceous female with grossly oversized breasts, was bending over a table while his sister had her way with him. Chantal’s belly rested upon him as she pressed her newly formed, oversized penis into his backside. Noticing his stumps, Magdalene had to ask, “What happened to your hands?” She looked to Gabriel, who turned weakly as his sister stayed in place, buried in his ass.

“She” Chantal paused for emphasis, “put a portal in my butt! I had to stop her from casting.”

Magdalene breathed deeply. “You two can’t get along for a day? You haven’t seen each other in a month and this is how you spend your time?” Her daughters said nothing. “I am going to have to punish you both.”

Magdalene unlaced her robes, allowing them to fall to the floor. She unpinned her hazel hair, allowing it to fall to her lower back. She inspected them expressionlessly, speaking a phrase, which caused a new member to grow between her legs, this one barely larger than her daughter’s. She said another phrase and moved her hands as her daughters watched with confusion.

Abruptly, Chantal lifted her hands and watched them absorb into her arms in a similar fashion to the spell she had cast on her sister. However, the spell was still continuing. They all fixated upon her arms, which were slowly melding with her torso. Magdalene watched impassively as her daughter’s arms vanished, leaving only smooth areas below her shoulders.

Chantal was breathing heavily as her mother reached lower and grabbed her posterior.
“It put the mass down here, I see.” The slightest smile came and left their stern mother’s face. She kneaded her daughter’s larger backside.
“Where did you learn to do that?” Chantal couldn’t help being amazed, viewing her malleable butt.
“I’ve forgotten more than you know, child.” Their mother spoke a few more phrases before she pulled Chantal back, causing her to slip out of her sister’s gaping rectum.

“Chantal, lay with your back on the table. Gabriel-la… climb on top.”
Gabriella looked nervous as she saw her mother’s enormous cock. “Actually, can I take that in the front?” Their mother nodded, stopping Chantal’s complaints. Gabriella backed up and sat upon her inflated sister’s slippery organ. Gabriella whimpered as she accepted the entire thing into her ass before she leaned backwards upon her sister. Once balanced, she allowed her mother to access her pussy.

Magdalene moved forward and held her daughters legs as she lined up her massive erection. She pushed forward once she felt the inviting warmth of her lower lips. She leaned forward and pushed in; this pressed Gabriella back onto her sister’s stomach. Magdalene heard them both whine and grunt in discomfort.

Gabriella felt her lower opening stretch painfully wide, but didn’t feel anything deeper; it was an odd sensation, but she knew the portal was doing its job in her sister’s ass. She could feel liquid expanding her already large breasts again. She placed her arms upon them, but her mother slapped them away. They sagged to her sides as her mom and sister fucked her. At this point, she regretted the portal in her front opening, as she could not get any womanly satisfaction, only pain in her backside.

Meanwhile, Chantal’s stomach was smashed under their weight. However, it didn’t compare to the sharp pain she felt in her backside as her mother’s rod pressed deeper. She laid in agony as her mother railed her unintentionally. She could see Gabriella’s breasts had grown even larger and now nearly rested on the table at their sides. Her stomach felt nearly empty, and now she focused entirely on the pain in her ass.

She looked up to see Magdalene losing her composure – her eyes rolled back and her chin quivered. Chantal felt a pulsing explosion in her bowels. Thick streams of cum coated her insides as her mother orgasmed. She could feel her belly grow and suddenly sink again. The portal was transferring the abnormally large amount of seed into Gabriella’s breasts, mixing with the milk. She could see her sibling’s breasts pulse outward with the thick seed before regaining their normal proportions.

Chantal desperately tried to hold back, but the sensation was too overwhelming. She started cumming into her sister’s ass without even trying. It felt humiliating as she pulsed, filling her sister’s rump as her mother had filled her. She was not above the carnal desires of men as she had thought. In fact, she adored this feeling. She blushed as she watched her mother regain her senses.

Magdalene slid out, leaving her daughter’s openings gaping and slick. She gathered her robes and dressed as her daughters lay there, completely wrecked. She spoke a phrase and helped Gabriella to sit up; Gabriella tried to hold her heavy milk laden breasts, but they were far more than armfuls and she had no hands to assist. She turned and rested them upon the table as she slid off.

“Drink from her bosom, Chantal.” Magdalene commanded impassively.
“Yuck, no. I don’t want to drink that! When you-”

“Quiet!” Magdalene came behind her buxom daughter and grabbed Gabriella’s engorged breasts. She squeezed and watched as Chantal’s posterior grew, her hips rising as the milk now filled her backside.

She was horrified. “Mom! Stop! Please!” Chantal begged.
“The more you drink the less you’ll have to carry around. It’s being absorbed into your rear.”
“No! That means my butt will be huge!”
“If you drink then it will just flow through you.” Chantal continued whining. “Drink!” Magdalene squeezed her daughter’s enormous breasts harder. They rested upon the table, but now they were returning to manageable sizes. Chantal leaned closer; her butt had doubled in size. Her small frame made her pear figure more pronounced.

She put her lips upon Gabriella’s erect nipple and sucked. The milk was thick and sweet; she didn’t mind the taste, but she knew she wouldn’t be able to drink very much. She could feel her butt grow as she tried sucking faster. After some time she was unable to drink any more of the sickeningly sweet, sometimes thick, milk, and finally gave up. Magdalene chanted another phrase and the flow stopped.

Chantal’s rump was halfway across the small table, yet the skin was still springy and tight. “It’s twice the size as it was! Please undo it!”

“You’ll have to work it off the old fashioned way now. It was already absorbed.”

Gabriella’s breasts were still easily the largest in the room, but they were nearly back where they had begun. Her mother patted Gabriella’s shoulder as she stood upright. “What do you think of your sister now?”

“At least she has a nice ass now.”
Magdalene waved her hands and spoke a spell.
They all watched as Gabriella’s hands began reforming; she moved them as she regained full motion, smiling with relief. “What about the rest?”

Magdalene stared callously. “I removed the portals, but the rest shall remain for tonight. You will take care of your sister.”
“What? You must be joking!” Chantal complained in a shrill tone.
“I am not. Any protest you may have shall wait until my return.” Chantal griped as Gabriella begged. Magdalene waved a hand to silence them. “I will hear no more. If you do not learn to respect one another then I shall be forced to elevate your punishment.” Magdalene nodded sharply before turning to leave.

As the door closed, Chantal knew that, without arms, she was almost entirely at her sister’s mercy. Gabriella smiled. “I have the upper hand now.” She snorted as she laughed.
Chantal rolled her eyes. “She will keep you as a girl if you do anything to me!”
“You know, I don’t really mind it. I love these things!” Gabriella grabbed her breasts. “And we only get punished if we aren’t getting along.” She smirked. “I will be somewhat gentle with you. I think we can play nice together, don’t you agree?”
Chantal sighed as Gabriella kneaded her supple apple-shaped bottom. “I guess so, but you have to let me do your ass again, okay?”
“Fine, but you have to show me how to get my dick back after.”
“Deal!”
Gabriella bent forward and grabbed her ankles. “Hurry up.” She felt Chantal’s rigid member sliding between her cheeks before it pressed into her already used hole. She could feel herself part as the thick piece of flesh pressed into her, filling her bowels. It took six deep thrusts before warm goo filled her as she leaned forward.

“Okay, show me how.” Gabriella demanded, her sister’s cock still buried in her ass.
“Nope, fuck you!” Chantal rammed deeper, before withdrawing completely, causing Gabriella to gasp.
“You bitch!”
“Remember, we have to get along!”
“Fuck that,” She reached back and hastily reinserted her sister’s organ into her backside. Chantal retreated, overpowered by the sensation. She backed to the wall; Gabriella followed her, pressing all the way on, accepting her organ fully. “I’m going to make you squirm!” Pinching her ass as tight as she was able, Gabriella moved her hips upon her whimpering sister.
“No, stop! It’s too much!”
“Nope, you had your chance. I’m in control now. I’m going to fuck you silly!” Gabriella looked back, grinning wickedly as she bounced back against her pinned sister. “I can fuck all night!”
