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.

Ohhh you're finally awake, sweetie! How do you feel? Ready to have some more fun with mommy? She asked while continuing to fondle and stroke your rock hard clitoris. Your pseudopenis throbbed against her hand as she expertly teased it back into full hardness again, not letting up even a bit on the pace or intensity of her touches. Her grin widened as she watched you writhe helplessly under her skilled ministrations.

It was obvious that there would be no escape from this carnal cycle. You belonged to your mother now, body and soul... and she intended on enjoying every last drop of pleasure from you until the end of time.

Mmm, that's it baby boy... just let your mommy take care of you. You feel so good like this. You know you belong to me now, don't you? Tell me how much you love being my son... tell me how much you want to be with me forever... tell me what a naughty little slut I am for doing all these things to you and making you mine! Tell me everything!
