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.”
“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.
