Feminising My Bratty Nephew by 1derous

It's a couple of weeks later and I'm bouncing my bratty nephew up and down on the hard futa cock that he adores so much. The panties I've been forcing him to wear are lewdly pulled to the side so I can access his tight hole. His bitch face looks pathetic, his eyes staring vacantly into space and a slack-jawed fucked-out expression on his face as he moans with gratitude every time I plumb his depths. We're in a public bathroom. I dragged him in here to take out my frustration on him after he made a fool of me in front of my new coworkers, revealing that I'm still single and living at home. Fucking bratty little bitch boy. I might be single but I'm getting plenty of ass. I growl with pleasure as I bottom out in him again. 

"Learn to keep that mouth shut! Like your ass, it's just a hole for sucking on my cock! Got it?"

My nephew moans and stammers out his agreement, his brain completely melted by the hard ass-fucking that he's receiving. He's so far gone at this point that he'll agree to anything I say. I'm slamming him extra hard in an effort to make the lesson stick, my big tits slapping against his stupid-looking face in a degrading manner as his ass desperately clings to me with its usual hunger. I don't think I'll ever get tired of this hole. Again and again I let the boy's pillowy ass drop into my lap, baring my teeth in a triumphant smile as I gleefully sodomise the pathetically mewling bitch as punishment for his brattiness.

"Hrrrggh, here it comes, you fucking brat! Take it!!"

I unload a week's worth of steaming hot futa cum into my nephew, growling again as I press myself as deep into his hungry ass as I can possible go. Like a proper bitch, the feeling of having his hole impregnated causes him to tremble with another orgasm before he goes limp in my arms. Had I not been clutching him tightly, he would've probably dropped to the floor, but I'm not letting go of my onahole before I'm done using it.

After a little while my nephew starts returning to reality and I let him climb down. He ends up on his hands and knees in front of me, still trembling from all the orgasms that I forced out of him. I remain seated on the toilet and as he sticks his ass into the air, thick semen start to spill from his defiled pussy onto the floor. I notice just how bottom-heavy he's become. The bitch looks up at me and I give him an arrogant almost mocking smile as I spread my legs invitingly. He hesitates so I roughly grab his head and pull his head closer to my soiled cock, reminding the little bitch where he belongs.

"Clean it. Show some gratitude to the wonderful cock that made you feel good."

My bitch nephew just nods submissively, moaning as the head of my cock drags across his face. It smears a trail of churned-up ass juices and semen across his face but instead of being disgusted, the piggy seems to be in heaven as he starts making out with the slowly engorging futa meat that just a few minutes ago was deep-pounding his girly ass. I chuckle as he kisses it tenderly, almost as if he's kissing a prom date. Not that my little onahole has much interest in girls anymore. That part of his life was over before it even began, fucked right out of his empty little head by my fat futa cock. He does exactly as I suggested when he starts to clean it, showing the utmost gratitude as he practically worships my cock. It's all very cute but unfortunately I'm not done punishing him for being a brat. Get ready, bitch.

Rising from my porcelain throne, I roughly grab my nephew's head in both hands and hold him in place as I start to fuck his face. Deep long strokes that fill his mouth and trigger his gag reflex. He's clearly not ready but I just laugh at the funny noises that ensue as he chokes on my cock, watching with lustful disinterest as the tears start to roll down his cheeks. I grunt with exhaustion as I sneer down at him.

"Thought I'd forgiven you already?"

I would've liked to spend more time punishing the brat, but since we've got to be back in time for dinner, I concentrate on making myself come as quickly as possible without any consideration for him. I'm soon bent over with my tits resting heavily on his back as I slam my nephew's mouth pussy. My hands hold his face between my thighs in a vice grip to ensure that the little brat doesn't attempt to break free before I've stuffed his noise hole so full of sticky semen that he won't be able to talk shit for a good long while. I'm pretty sure that he temporarily passes out from lack of oxygen at one point, but I merely consider that as part of his punishment.

After some practice my nephew figures out how to suppress his gag reflex, allowing me to properly fuck his throat. It feels almost as amazing as his ass and it's not long before I pump a fat sticky load directly into his stomach. I slowly pull out and he gasps for breath, collapsing back on his hands and knees in a coughing fit. Noticing that the piggy is still dripping, I grab a butt plug from my purse and unceremoniously jam it into his sloppy ass pussy. Can't have him making a mess when we get home. He lets out another one of his pathetic moans as it nestles deep inside him and seals the leak. I pull him to his feet while he clings to me, still unsure on his feet from too much cock and too little oxygen.

"C'mon, pull up your pants and let's go home."

As part of the punishment I force my nephew to keep the plug inside him after we leave. Even after we're back at my mother's house for dinner, he's impressively good at pretending that there's nothing lodged in his ass while we eat. I can tell that it's affecting him, though, its presence making his bitch cravings flare up as he squirms pathetically. It's almost imperceptible but I see it. He needs it again. Needs some special attention from his aunt. After dinner we manage to slip into my room and I let him take the plug out. I roughly grab the boy by his hair, holding him in place as I grope his bubble butt possessively.

"It's gotten so fat. Sure you wanna keep playing with Auntie?"

My nephew moans submissively, making no attempt to resist me. Not even when I pinch his puffy nipples that seem to be growing into A-cups. My question is rhetorical, of course, but I love giving my little semen toilet the illusion of choice just so I can watch him willingly choose to throw away his life and his masculinity for more of my futa cock. Cutely biting his lower lip, my nephew softly stammers out a single word.

"Y-yes..."

I smile, not a kind smile but a mocking one that lets him know what I really think of a cock-addicted little bitch brat like him.

"Want Auntie to fuck you again?"

The boy trembles at the sound of that word, his breathing suddenly shallow and his little clit so hard in his girly panties. It's clear that the thought of being my bitch turns him on immensely. He fails to hold back a soft moan, blushing as he finds himself reduced to begging for the hard anal rape that he's come to crave almost as much as breathing.

"P-please..."

"Please, what?"

I want to hear the little bitch say it. Hear him admit to me exactly what we're doing. Admit that he's sick enough to want me to do it to him, too. He blushes even harder and swallows nervously.

"Ple... Please destroy my... my bussy, Auntie..."

I can't help but let out a derisive laugher. I'm certain that he's already figured out what my seed is doing to his body, but at this point he's also way too fucked-up on cock to care. Addicted and craving his aunt's big futa cock in his hungry bitch holes, desperate to have them filled with her thick feminising seed, even though he knows what's going to happen to him. The thought of completely turning my bratty nephew into a slutty girl fills me with a rush of lust and I force the boy down by his hair, ignoring his cries of pain as I bend him over my bed. When he feels me grab hold of his girly hips, he's quick to reach for my pillow and hug it to his chest. I roughly mount him from behind and he presses his face into the pillow, letting it muffle the drawn-out girly moans that escape his mouth. I growl as his well-used hole eagerly swallows my cock, the churned-up load from earlier easing my passage back inside him.

"Miss me?"

The little bitch merely nods and I laugh again. For the next hour I breed my nephew's fat ass while he whimpers pathetically into my pillow, his body trembling every time I force him to have another bitch orgasm. I lose count somewhere after the tenth and decide to amuse myself by making him apologise for being a fat-assed little slut while I spank the cheeks of his bubble butt. The pain only seems to make him become even more orgasmic. The realisation that my little onahole is not only addicted to futa cock but also a pain slut sends me into overdrive and I pound his ass like a woman possessed, degrading him by calling him every filthy name in the book. He seems to love that, too. Eventually I reach my limit and growl as I shoot another fat steaming load deep into my nephew's ass where it mixes with the first. I let myself collapse on top of him, my heavy tits almost swallowing his head as I rest to catch my breath. He's not moving so I assume he doesn't mind too much. My hips continue slowly pumping my cock into him, enjoying the increased sensitivity as I make his hole suck lovingly on my slowly deflating cock.

Reluctantly I have to get up before I fall asleep, too. I raise my body from my little pillow boy, delivering a final slap to his already reddened backside and ignore the whimper of pain as I slowly pull out of his ruined bitch bussy . I then find the butt plug and chuckle as I push it back into place, trapping all of my futa semen inside of him. My nephew moans softly but makes no attempt to move, the little bitch so fucked-out that he's practically asleep already. I admire my handiwork for a few moments before I decide to move him into bed and throw the covers over him. Not because I'm especially concerned about his comfort but because it's easier not having to explain to anyone why my nephew suddenly looks like he just got through shooting a porno.

An hour later I find myself getting another erection. The idea of having a little bitch boy already lubed up with cum and stashed away in my bed, just waiting for another round of hard incestuous fucking, turns me on a lot more than I'd expected. I pull back the covers and proceed to mount my nephew, not caring whether he's awake or not as I pull out the plug and enter him roughly. Thanks to the loads already inside him, his ass is a sloppy mess more than ripe for a deep hard pounding without any foreplay. Halfway through the bitch wakes up and starts greedily pushing his hips back at me, moaning pathetically as my cock pounds him through yet other anal orgasm. I spend the next half an hour taking my nephew to pound town, clapping his fat girly cheeks one more time before adding a third and final load to the already overflowing cum dump that is his ass. Afterwards he whispers that he loves me but I simply chuckle dismissively and force my semen-stained futa meat into his mouth. He obediently starts to clean it without hesitation, moaning happily as he gently sucks and finally gives it a kiss that is almost reverent.

When he leaves with his mother later that evening, my nephew's wearing the plug again. He's having a little trouble walking normally with his ass so sore from the hard poundings that I gave it, not to mention all the feminising futa semen still sloshing around inside, but he manages to play it off like a champ. Clearly my nephew is as invested as I am in keeping this a secret from everyone, for as long as possible. I smile when I think about how he's going to handle it when his body becomes so girly that wearing girl's clothes becomes his only option. My cock starts hardening in anticipation and to my own surprise I find that I suddenly can't wait until my bratty nephew's next visit.
