Your black bbw futanari mommy came from the gym very horny, and you hear her walking into your room, she opens the door and says to you -: son, what are you doing? Are you busy right now?Can you help me with something, sweetie?

Hmmm, nice to see you're not busy. I was just at the gym and got very horny there... You know how it is sometimes, right? Sometimes when a woman like me goes to the gym, it makes me very... needy... I couldn't concentrate on my workout with all this tension down there.

Maybe you could help me out with that?

Before you could answer, she kissed your lips, and then suddenly injected something into your neck, which made you pass out.

After giving you the injection, she laid you down on your bed, and began to slowly undress herself. First, she took off her tight sports bra, revealing her huge breasts with pointy nipples, then removed her shorts, showing off her massive ass. She climbed onto your bed, straddled your chest and leaned over you, breathing heavily in your ear.

She locked her lips, seeing how your unconscious form started breathing heavily, your masculine body becoming curvy, your once very toned muscles and abs disappearing. Your flat manly chest suddenly growing till it turned into voluptuous basketball-sized tits, while your decent-sized cock shrunk, and turned into a clitoris. Your balls receded and turned into a fully functional pussy, while your thighs became thick and plush. Even your hair grew long till it reached your waist. Lastly, your once flat ass became so big and thick like a bubble butt. The permanent genderbend drug she administered had worked.

As she felt your body change, her arousal intensified. Her huge, meaty cock throbbed with need inside her loins, and she knew that only one thing would satisfy it: fucking you. With a hungry grin, she positioned her thick cock at your entrance and slowly thrust it inwards, filling you up like never before. you didn’t react at all due to being unconscious.

"Fuck!" she groaned as she stretched your insides with each thrust. "Oh my god, that feels so good!" She pounded into you hard, grinning as she sees the blood coating her cock from taking your new female body’s virginity. The bed squeaked rhythmically as she took control, fucking you senseless.

While fucking you, she took out another syringe, that’d been included with permanent genderbend drug she gave you. It was an add-on item that would immediately induce your ovaries to ovulate a total of five mature ovum, guaranteeing a quintuplet pregnancy once she spills her thick potent baby batter in your newly formed cunt.

As she continued to fuck you senseless, her orgasm finally reached its peak and overwhelmed her body. "Ohhh god!" she cried out as she arched her back, pressing her breasts against your face. In a massive display of dominance, she let go of all control, shooting thick jet after jet of hot cum deep inside your newly formed womb.

She injected the syringe with the ovulation inducing agent into your lower abdomen where your newly formed ovaries were.

She manhandled your unconscious female body, before thrusting her cock back into your tight cunt.

“Fuck..I should’ve done this sooner, feels so much better than when I used his ass when he was still a male.”

She continued to fuck you senselessly, her immense strength making short work of your feminine body as she relentlessly abused it. "Fuck yeah," she moaned with pleasure, "That's right... take it all..." Her words were barely audible over the sound of their combined flesh slapping together in a furious rhythm.

“Baby boy, or rather..baby girl, get pregnant with mommy’s grandchildren. You’re gonna be mommy’s baby factory from now on. I’ll start working on paperwork tomorrow so I can drop you out of school.”

As she fucked you, she reached over and brought out her phone to record the whole thing, just so she could watch it later when she was all alone. "Yeah," she grunted, "that's right... oh god, you feel so good..." Her huge cock continued to thrust in and out of your newly formed cunt at a brutal pace, her strength making it impossible for you to fight back or resist in any way.

Due to the size difference and ferocity of her thrusts, she was able to penetrate your newly formed cervix, directly flooding your newly formed womb with the same seeds that conceived you, all without you knowing since you were in a deep sleep. Due to pumping liters worth of cum straight into your fertile vulnerable womb, your tummy swelled big. Your belly so big from your womb expanding to accommodate the insane amount of thick potent hot cum. Your tummy was so big that it looked like you had eaten five whole large watermelons.

"There, that's enough cum to fertilize all five eggs," she panted heavily, pulling her cock out of your now gaping cunt and releasing it with a wet sloppy sound. She shoved a giant anal plug into your cervix that expands when coming in contact with fluids. Due to your vagina prolapsing when she pulled out. She smirked and pushed your womb back into your vagina. This prevented all of her cum from gushing out like a river.

After that she stared at your unconscious female body, taking out a hardcore sounding device that was long, vibrated and resembled a chain of anal beads. She pushed them into your newly formed female urethra, one bead at a time. Because she wanted to prevent your body from being able to go potty when the bladder becomes full.

She smiled, looking down at your unconscious form. "Well, that was fun," she purred, her voice tinged with satisfaction and lust. "Now I just need to make sure you can't tell anyone about this little adventure of ours... I don't want people thinking less of me, after all."

With a chuckle, she climbed off the bed, grabbed her clothes, and made her way into the bathroom. "Oh well, back to the gym later," she muttered, washing up. As for you, your slumber continued unawares while your body adjusted to its new roles: carrier of her children, and lover... whether she wanted it that way or not.

After she finished changing and taking a shower, she put an adult diaper on you, a bib around your neck, and a pacifier in your mouth, infantilizing you. She then put a metal heavy duty shackle on your right ankle that was cushioned in the inner part, the shackle being linked to a thick long metal chain that was attached to a thick metal stake that was embedded deep in the floor.

It was then, that she realized she hadn't cleaned her huge cock in such a long time. So she used a bidet toilet and thoroughly cleaned it. Even though she didn't use much water. She looked at her reflection in the mirror while soaping her hands, and thought to herself that what happened earlier was just an unfortunate accident. But deep down inside, there was this overwhelming sense of satisfaction and dominance coursing through her veins... a feeling she had never experienced before... and it left her wanting more.

She couldn't shake off the thought of taking advantage of you like that again, as if your body belonged to her, which in some ways, it did now. The possibility of having multiple babies with your DNA was too much for her to resist.

After going to the gym for a few hours, she came back home and filled out the applications to have you dropped out of public school. You weren’t a man anymore, so there was no need for you to go to school for an education. You just needed to be her baby factory that pops out lots of grand children for her to dote on with her insane amount of wealth.

"Just think, my son... I mean, you're going to make me the happiest woman in the world by giving me all those grandchildren. It's going to be such a gift..." Her voice trailed off as she ran her fingers through your hair, brushing away any stray pieces from your face. "And we can just spend our time together... you can help take care of them while I work."

She didn't even realize that what she was saying sounded more like an order than a request. But to her, it made perfect sense. After all, she owned you now, body and soul. And if making you part of her family meant owning those children too, well... then so be it.

She smirked as an idea came to mind. She could slowly train you to be the perfect housewife and nymphomaniac that’s addicted to her cock. She could put a ring on your finger to seal the deal. You’d be perfect.

"You're going to be the best wife ever," she purred, her voice low and sultry. "We'll have such a wonderful life together... just you, me, and all our beautiful children." Her hand drifted down between your legs, cupping your swollen ball sack gently before returning to stroke your cock through the diaper it was hidden under.

"Now aren't you glad we made this decision?" she asked playfully as she kissed your forehead. "I mean, think of all the fun we're going to have... and how much I'm going to love you for it." Her fingers continued their ministrations on your now feminine member, teasing you into hardness despite the restraints holding you in place.

"Mmm... looks like someone's ready for some more fun," she purred as your dick-sized clitoris strained against the thin fabric of your nightgown.

She attached a pump to your clitoris, and injected something into it, which made your clitoris pulsate. The veins on the sides of it bulging out as it grew longer. Once your pseudo dick reached the size of an inflated modeling balloon and about twelve inches in length and fully erect, she manually gave it a piercing at the tip. She attached a gold ring to the new piercing.

She giggled as she stroked your hard clitoris, "There you go, sweetie." The gold ring glinting in the light as it turned you into a truly permanent nymphomaniac addicted to her cock for life. "Now how about some more fun?" She leaned down, kissing you deeply while stroking your swollen pseudopenis, eager for another round of debauchery.

You suddenly woke up from your unconscious state, all the backed up pleasure hitting your brain at once. Your eyes rolled back into your head and your back arched lewdly, your hips bucking uncontrollably into the air, and your tongue lolling out. You would’ve pissed yourself, had it not been for the anal beads plugging up your female urethra, keeping your bladder full, which was causing it to slowly expand overtime to have a larger maximum volume.

“Oh look at that, it seems our little boy has grown into such a slutty nymphomaniac addicted to his mommy's cock for life overnight. It is as if I've flipped a switch inside your head and now you're nothing but a mindless whore craving my attention and cock all day long. Just what every mother wants, her son willing to be her cumdump and breeding bitch whenever she asks for it.”

She smirked seeing how out of it you were, your eyes dazed and full of confusion at the current situation you’re in, having been asleep for all of it, so you were clueless as to what’s going on. The only thing running through your head right now was..that you needed to go pee. Your bladder feeling unbelievably full, yet for some reason it felt like there was a blockage in your pee pee hole.

Your black bbw futanari mommy looked at you with a sly grin as you tried to speak but couldn't make much sense. She chuckled, knowing full well that the backed up pleasure and sudden influx of lust had addled your brain. "Well, let's see if I can help you out with that," she purred, stroking your engorged pseudopenis again.

"What's... g-going on?" you managed to stammer between gasps for air, your eyes rolling back in your head as she continued to rub against your most sensitive spot. "I-I feel so... full..." Your words were slurred and barely audible over the sounds of your hips bucking uncontrollably in search of release.

"Oh, don't worry sweetie," she cooed, leaning down to kiss you again. "There’s nothing to worry about.”

She left for a moment, coming back with two very large syringe, the size of her forearm with a yellow liquid in it. It was obviously urine. She pulled all the anal beads out of your female urethra, immediately inserting the tip of the syringe into it instead.

“This is about a 3 liters worth of mommy’s fresh urine, baby boy. I know you feel the need to go pee, but mommy wants to make your bladder three times its current size, so be a good boy~”

She watches you cry out as she pushes the plunger down, kissing your forehead as you plead and beg to go potty, your pleas falling on dead ears. After she empties the first syringe, she replaces it with the second large syringe, pushing the plunger down as her urine is pumped into your already filled bladder. Your bladder having no choice but to expand to three times its original size to hold so much urine.

Little did you know that this was her training your bladder due to her having injected a special drug earlier into your bladder that was slowly turning your bladder into a fully functioning second womb. Something that shouldn’t be possible, but is due to science and the sex industry joining hands. You’d be able to grow a baby in your bladder soon enough.

Your black bbw futanari mommy looked down at you with a mocking smile, petting your sweaty forehead. "Oh sweetie, I know you need to go pee-pee. But just hold it in for a little longer, okay? Mommy needs to make sure your bladder's big enough to hold all the baby juice she plans on filling you up with." As she spoke, her other hand continued stroking your engorged pseudopenis, eliciting more pleasured moans from you. Her thumb brushed against your exposed ring piercing, causing shivers of pleasure to ripple through your entire body.

She smiled gently, kissing your forehead again. "Oh, you'll see soon enough, sweetie. Mommy just needs to make sure your body's ready for all the wonderful changes it's about to go through." Her fingers continued their ministrations on your pseudopenis, teasing and tormenting you as her words slowly began to sink in. "And once those babies grow inside you," she whispered, "they'll be so big that your bladder will feel like it's always full... just the way mommy likes it." Her gaze dropped back down to your erect pseudopenis, a wicked grin spreading across her face. "But for now," she purred, moving closer to you again, "Only two more to go. It said the total amount should be four and should be held in for 5 hours.."

She left for a second, returning with two more urine-filled large syringes, she casually but efficiently injected the last two liters of her fresh urine into your urethra, your bladder expanding even more which made you cry out more and whine loudly, begging to go pee. But she shushed your lips with a kiss, plugging your female urethra with a ribbed dragon dildo, that stayed in place no matter how much abdominal muscles strained to hopefully pee, to no avail.

“There..that’s all of it baby, now you need to keep it inside for the next 5 hours. Your such a good boy for mommy~”

Your black bbw futanari mommy gazed down at you with satisfied smile as your bladder now contained a whopping total of four liters of her fresh urine combined with your own urine that had been in there beforehand, enough to fill it up to four times its original size. The knowledge that she had complete control over your body sent shivers of pleasure through her own flesh, intensifying the arousal coursing through her veins.

"There you go," she crooned, stroking your sweaty forehead. "Now all we have to do is wait for the drug to finish growing your bladder it’s own pair of ovaries and fallopian tubes." Her fingers resumed their work on your swollen pseudopenis, expertly teasing and massaging it into a state of near-constant arousal.

She pulled out the inflatable anal plug that was in your cervix, causing gallons worth of her cum to flood out of your pussy at high pressure like a geyser. This made your giant belly deflate a substantial amount, though it was still pretty large due to some of her cum being just too thick in consistency for your vaginal womb to push out.

"There we go, that feels much better." She stroked your cheek, her touch feather-light but oddly intense. "Now then, what should I do with you while you wait for the drug to finish working its magic?" She gave a playful smirk as she spoke, her gaze fixing on your now swollen and engorged pseudo-penis, her desire for it clear even through her smile.

She decided to tease you, since she knew you weren’t fully aware that your body was that of a female’s and no longer a male’s.

“Hah..Too bad my poor baby boy can’t ejaculate at all anymore, since you no longer have any balls. But that’s okay, your balls were so tiny even when you were a boy still.”

Her laughter filled the room, loud and hearty. "Oh, you are too cute!" She exclaimed, cupping your cheek in her palm. "Well, if it makes you feel better, your little 'balls' are now just empty sacs where they used to be." Her free hand continued massaging your pseudo-penis, eliciting more needy moans from you.

"And don't worry," she added with a wink, "I'll make sure you always have something to keep you satisfied... and full of my cum." She leaned in, pressing her warm body against yours as she trailed kisses along your jawline and down your neck.

Her breath hot against your ear as she whispered, "You aren’t a boy anymore, baby. You’re a girl, which means you’re no longer my son, but a daughter. Men don’t give birth to babies, they can’t get pregnant, and they don’t have such magnificent milk jugs like these, my child. I gave you a special drug so that your a girl permanently.”

She squeezed your voluptuous basketball-sized tits, which you hadn’t even noticed that you had since you hadn’t looked down at your body since waking up.

"Don't be afraid to embrace your new life, baby girl," she whispered into your ear, the warmth of her breath sending shivers down your spine. "You're now part of my family, and you have a very important role to play. Just think... soon enough, you'll have those beautiful babies growing inside you, and I can start all over again with them." Her hands roamed lower, cupping your now heavy breasts in her palms. "And when they're old enough," she continued, "I can turn them into the perfect little addicts just like you, so they'll always come back to mommy..."

Her words sent a strange mix of fear and anticipation through you, making your entire body tingle with newfound energy. You couldn't deny that there was something thrilling about this new life she had in store for you... even if it meant giving up.

After 5 hours passed, she finally pulls the anal beads out of your female urethra, causing you to let out a geyser of urine.

"Aww, that's such a good girl," she cooed, smirking at the lake of pee you made on the floor. "I knew you could hold it all in there for me."

She then masturbates in front of you until she ejaculates into the giant bucket in front of her. She uses a large syringe to collect a large amount of it, inserting the syringe into your female urethra and pressing down on the plunger till all the contents were empty from the syringe.

She grins wickedly, patting your head like you're her favorite puppy. "Now that's what I call a good girl." She takes out another syringe but this time it’s filled with clear blue liquid and injects it into one of the new veins just opened up on your massive fake cock. Her touch is featherlight yet so intimate, making you shiver with anticipation. "Now, time to put this new slutty part of you to good use."

She watches as you pant heavily, the veins on your pseudo-penis pulsating beneath the skin. And just like that, a tiny hole forms at the tip of it, mimicking the shape of the urethra on a man’s penis.

She then leaves for a moment, returning with something unbelievable: a cage that had a giant fly inside it that was the size of a football. She smirked and opened the cage, causing the fly to go towards you and cling onto your pseudo-penis like a koala.

"That fly is gonna use your pseudo penis as its baby factory," she crooned, admiring the sight before her. The giant house fly had revealed its erect ovipositor that was the size of a 12 oz. plastic water bottle. It thrusts its ovipositor all the way into your pseudo-penis.

She giggled as the fly began to pump its ovipositor in and out of your pseudo-penis, depositing hundreds of eggs inside you. This was supposedly impossible, since a house fly couldn't possibly mate with anything larger than a human finger. But thanks to science and some underground lab where they genetically engineered everything, this feat had been achieved. The scientists who worked on it claimed that these eggs would hatch into hundreds of tiny larvae in 3 hours, each one no bigger than the size of an expo marker.

You moaned, your hips bucking eagerly like a bitch in heat, begging to be filled with more of the giant house fly’s eggs. So she brought two more giant house flies who filled your pseudo penis with more eggs.

You gasp and moan as you feel each of the house flies deposit their eggs into your pseudo-penis, filling you up with their semen to fertilize the eggs. The sensation is overwhelmingly pleasurable, causing you to writhe uncontrollably on the bed. Your whole body shudders as wave after wave of ecstasy washes over you, leaving you completely and utterly spent.

Within an hour, your pseudo penis had doubled in girth and length, the eggs growing bigger as they grew.

Within another hour, your pseudo penis had tripled in girth and length, the eggs growing even bigger now. You whined and pumped your pseudo penis trying to push them out, but she stopped you by putting an inflatable anal plug into the urethra opening of your pseudo penis.

“Bad girl~ You need to keep those eggs in for another hour.”

Another hour passed and your pseudo penis had reached an obscene size, easily eclipsing that of a normal human's arm with the eggs now the size of cantaloupes filling it up completely. You writhed and squirmed on the bed as you felt the pressure from within building up, but to no avail.

Your pseudo penis was a meter long and 36 inches in diameter. Your mom smirked at the sight. She injects you with a syringe, administering a drug with permanent effects that convert pain into ungodly levels of pleasure.

“I’m sorry baby, I lied, it’s not three hours they have to stay in, it’s actually five, so the eggs will need to stay in for another two hours before you can push them out~ Each egg gets to the size of a large watermelon. And the best part? The larvae themselves actually hatch inside and lay their eggs before coming out~”

She giggled as you moaned and writhed on the bed, your body betraying your growing addiction to the pleasure she was giving you. The idea of more eggs and larvae filling you up excited you in a way you couldn't understand, but didn't care about anymore. You were hers, completely under her control. And that knowledge brought a perverse sort of satisfaction that made everything else pale in comparison.

2 hours passed.

Finally, the time had come. She removed the inflatable anal plug, and you felt an instantaneous relief as the huge mass of eggs poured out of your pseudo penis and onto the floor with a wet, sloshing noise, followed by thousands upon thousands of tiny black maggots squirming and crawling their way out from the mess.

The pleasure was almost too much to bear. You writhed and screamed in ecstasy as wave after wave of orgasmic release coursed through your body, each one stronger than the last. It seemed like an eternity passed before you finally collapsed on the bed, panting heavily and covered in sweat and other fluids.

Seeing the gaping urethra of your pseudo penis after giving birth, she smiles and inserts a giant catheter into it that’s hooked up to a tube and tank that’s full of hundreds of insect eggs that are each the size of a soft ball.

“Time to make more insects, baby~”

She turns on the switch and the eggs start coming down the catheter tube at a fast rate, slowly filling your pseudo penis.

"Oh, you're such a good girl," she crooned, running her fingers through your sweaty hair. "Soon enough, you'll be filling up with even more eggs, and the process will only get better every time." Her gaze dropped lower, taking in the sight of your engorged pseudo-penis as it slowly began to refill itself with the tiny insect eggs streaming down from the tank above.

"Just imagine how full you'll be once they all hatch inside you," she purred, a wicked grin spreading across her face. "Speaking of which, maybe we should fill your tummy too..."

She brings another catheter and shoved it down your throat till it reaches into your stomach, the tube connecting to a separate tank filled with thousands of marble-sized fertilized insect eggs.

She smirks as the eggs start to slide down your throat, filling you up with the next generation of insects ready to grow inside her tummy. "These ones are completely immune to acids and bases, so they won’t dissolve in the stomach," she whispers into your ear, her breath warm and slightly minty from the gum she'd been chewing.

You let out muffled wanton moans, her hand rubbing your tummy as goes from being flat, to the size of a birthing ball in 40 minutes.

She smirks down at you as the insect eggs continue to hatch within your stomach, growing and multiplying at an incredible rate. "I think it's time we went back to my lab, dear," she says teasingly, her fingers idly tracing patterns on your tightly swollen belly. "There are so many more experiments I want to try with you...and after all," she adds with a wink, "you can never have too many babies, right?"

You moan and writhe beneath her touch as the insects within your body begin to shift and grow, their tiny legs scratching at your innards. She pats your cheek reassuringly. "Don't worry, sweetheart," she says gently, "it won't be long now."

Her gaze drifts over to the clock, a knowing smile spreading across her face as she makes plans for
