From Behind

(A horror themed butt growth story.)

Why do you keep doing this to yourself? It’s like you set yourself up for disaster. You are travelling home alone from a rather productive session at the gym. That is the good news, the bad news is you have just entered what is known as a run down area of town affectionately referred to as ‘The Crack’, everyone tends to avoid it if possible. There have been recent reports of missing people in the area too, but no one is very surprised, or seems to care. But today you were in a rush and despite your reservations, this was the quickest route back. At least, in theory.

Passing down a street of derelict warehouses you notice a side passage that appeared to lead down an alleyway. That was odd. You’ve been down here before, but had never noticed this back-alley before. Paths don’t tend to spring up out of thin air. You try and calculate where it should lead and come to the conclusion that it would let you save some time, maybe? Look, it’s extremely unlikely anything bad could happen within the minute it would take to make it through to the other side. Yes, that is what everyone says before things go horribly wrong but that was absolutely, definitely not going to happen here.

You step into a puddle that splashes an unidentifiable liquid up your bare leg. Mental note: never wear shorts in ‘The Crack’ again. Trash was piled up high on either side, it was obvious these buildings didn’t get a huge amount of use anymore. You always thought horror movies had done a real disservice to alleyways, but this one certainly wouldn’t be changing anyones mind. In the distance you see the silhouette of someone standing in the middle of the alley. From their stature it seems to be man, but something about them throws you off. You feel a pang of trepidation, a chill runs down your back. It’s only just occurred to you how deafly quiet the passage is, the sounds of the street feel like miles away. You turn around and the uneven pavement seems to impossibly stretch away from your feet. You hear a dull droning, fizzling just within your hearing range. Looking back and the man appears closer than before, you swear he hasn’t moved and yet…

“Uh hello?” You call out, to no response. Strange. But then, you see it. The most beautiful sight your eyes have been graced with. His butt.

Butt.

His grey joggers are having a hard time trying to contain what he’s packing, not that you’re complaining. It’s bigger than what you thought possible, it’s captivating. And now you’re just staring. Staring at another dudes gigantic butt in the middle of an alley, try not to overthink it. You see it jiggle just slightly and your eyes follow it’s repetitive movement hypnotically. What doesn’t occur to you is how your body is starting to….adjust. There’s a barely perceptible malicious force entering your form, you welcomed it in the second you laid eyes on the perfectly sculpted ass. Not a wholly bad trade off.

It wastes no time in making itself at home. Assessing the prey that wandered into it’s lair, before going to work on you.

The energy is gathering in your nethers, passing down your head and pulling through your torso. It seems to be taking something with it as your rear begins to heat up. You feel a light throb. It starts slow but soon increases in intensity. Your modest stature is being ‘enhanced’, your average ass cheeks piling on pounds as the rest of your body flattens out. Muscle and tissue is consumed, just food to bolster your hindquarters. All your body fat melts away until you have a tight slim chest. Your arms thinning out into effeminate twigs, hands slender. And through it all you continue to watch the rotund cheeks in front of you, not daring to take your eyes off them. Wouldn’t it be nice to have that too? Any sacrifice would be worth it, no? You want that, that -

Butt.

The thin polyester fabric of your shorts is pulled taut across your enlarging rear. Straining as it struggles to cage the hungry beast within it’s confines. Today was perhaps not the best day to decide on going without underwear. But lets be honest, underwear isn’t going to have much prominence in your future.

With your body adequately slimmed down, the insatiable parasitic-like force begins to target any identifying features you have left. It focuses on your head, a couple of twitches and it’s done. Nose itches, eyes water. It leaves your face with an uncanny quality, like it was unsettlingly sent though a algorithmic generator. It’s you, but an eerie idealised version of you. Plasticised perfection. Your skin is now unnaturally even, without a single speck or blemish. Anything that could distract from your main asset is smoothed clean. Absorbed by the mound of flesh expanding in your pants. There’s only one thing people should be paying attention to. That’s quickly becoming less of an issue. The inevitable missing poster they put up will only vaguely resemble you.

“Guh.” You hear yourself pant.

The low droning of the alleyway grows more prominent, pulsing rhythmically, akin to the low bass of a dance track. Your buttocks instinctually vibrate to the beat.

It’s increasingly hard to ignore the obvious changes happening to you. Your rotund behind is becoming so heavy. And while, yes, it is slightly concerning - can the issue wait just a little bit longer? You’ll deal with it later, after fully grasping the scope of this dude’s bountiful booty. For a second you wonder what the mans face looks like but then you think better of it. His face isn’t important, in the same way that yours isn’t.

You shift your feet apart, trying to balance out your rear heavy centre of gravity. The slight movement sends your round cheeks wobbling comically like a bowl of jelly. They bounce together, creating a wet slapping sound in your tight shorts. Your lower half is at risk of putting fuck toys out of business.

You’ve never had the word ‘butt’ enter your mind with such frequency in your entire life, it begins to loose all meaning. A collection of random letters.

Butt.

Are you perhaps forgetting something? That 4 letter word isn’t about to share a space with that bump between your legs. At some point you may have believed your cock was of some importance. All those times it had made you feel good, where for a second your concerns would fade from view. But things change. You are changing. Sometimes you have no choice but to embrace it. You start to feel a light tugging at your crotch. It’s slightly uncomfortable but there’s a pleasant tingle too. You reach down and feel it’s length diminish within your hand, sucked up like a vacuum by your ever thickening arse. It doesn’t stop until a mere nub protrudes from your groin. It dribbles the smallest amount of pre down your leg and spreads across the cracked concrete of the alley. No amount of stimulation is going to produce much down there. Your pleasure centre realigns a little further back. A deep itch that requires constant attention. A cock is something that other people have, you instead have an open socket for them to plug into.

Your shapely bum must almost rival that of the one your eyes are glued to. Not much further to go. Other people will stare at yours in the same way. You didn’t know you were so jealous of it but who wouldn’t want THAT?

You’re not sure how long you’ve been watching his rear end, or how long you plan to continue doing so. No better ideas come to mind right now. That might be because with your body and cock sucked dry, your brain is the next best source of fuel. So much useless power being used up there, where it can serve a much better purpose. It’s like a battery being drained, squeezed right into your juicy fat ass. Churned away just to add another inch of thickness.

You don’t think you really want this to happen, maybe you’re big enough back there? But what you want and what it wants are two very different things. Unfortunately for you, it doesn’t appear to be up for debate.

If you round up all those little idiosyncrasies of your personality, you might even squeeze another few millimetres into your hips. There’s only one thing around here with much substance anymore, and it certainly isn’t your brain. You can admit it, not much of value has been lost. It’s not like you were getting around to solving world hunger. At least now you have the opportunity to solve a different kind of hunger.

Your thoughts provided a decent amount of sustenance as they were sucked out of your brain through a figurative straw. You feel the benefit push out. Your hips flaring out instantaneously while your globes inflate to the size of footballs. With your brain emptied out of anything complex, thoughts and instructions to your body start to arrive from the new master of the domain. Neurones rewired, your butt was now command central, your head was just the go between, mostly irrelevant. Simple instructions and desires like ‘bend’, ‘twerk’ and ‘facesit’ overwhelm you. But -butt- right now the main one was ‘stare’; you weren’t done yet after all.

Your cheeks moisten as they rub together, their new sensitivity firing bolts up your spine. Your shorts grow damp as the leaking fluid soaks into the polyester and clings tightly to your skin. It only helps to make your arse seem bigger, the fabric bunching up between your crack, creating a noticeable crease down the centre that leaves nothing to the imagination.

Once again you feel your ass throb and shudder, each jiggle pushing it just a little bit further from your body. Just when you think you couldn’t get any bigger back there, it keeps going, inflating to cartoonish proportions. Sticking out like a depraved shelf. Your waist thins out and your hips expand to accommodate your new form. Women would be jealous of what you’re packing, and men will be queuing up to test it’s suspension.

It’s okay to smile. Happy people smile. Aren’t you happy? You must be, everything else in your head was consumed. The entity did you a favour in that regard. Think of the words ‘bouncing booty’. Go on, give it a try.

Your lip quivers in a last ditch effort of restraint. Don’t let ‘it’ win. The defiance is vaguely amusing in a pitiful way but your face muscles start to give way. Your mouth stretches wide into a broad, earnest grin. The most sincere display of joy you’ve ever shown, who cares if it makes you look ‘dumb’? It doesn’t bother you at all that people can take one look at you and accurately guess, that not a single word of value will exit your mouth. Dumb people are happy. Why worry? You had different priorities now. You can feel safe knowing that your most prominent feature is taking the lead, that it knows what’s best for you. Give it the keys and good things are bound to happen.

See, and doesn’t smiling feel good? Doesn’t it feel right to smile as your hole is used like a cum receptacle? Or when your cheeks are surrounding a mans face? People don’t want to see their toy sad.

A lone giggle falls out between your pursed lips.

You reach back around and place your hands on your two buttocks, your palm is dwarfed in size. It no longer stretches across its surface. Like palming a basketball. You can feel it push against your fingers with immense pressure as it expands within your grasp. Just another centimetre, and another. It’s curvature widens, expanding out from your hips. You press your finger into the skin and rub. The surface is completely smooth and the texture has a slight friction to it, creating a light satisfying sqk. No one for a second will believe that it’s real, it’s obvious fake-ness is by design. Authenticity is so overrated, nothing real would bounce so tightly back to position, would shine so brightly in the light. Would be able to withstand so much pounding… People don’t actually want real, they want a fetish image come to life, they want no maintenance, no downsides. They want someone to just nod and agree while they fuck them without concern; they want a rubber butt like yours. You’re not about to question it, and neither will anyone else.

They won’t question it while they undress you, or while they find relief inside of you, or even when their own butt begins to expand. And still, when they are reduced to just another butt boy, they won’t question it.

Butt.

That’s right, you’re a carrier. You have been entrusted with a important task, to leave a string of giant asses in your wake. You need to spread it, like a computer virus. Once they ‘plug in’ there’s no going back. Whoever they were, they’ll all end up the same.

You are finished. Your glutes tighten into place. And your hole opens for frequent visitors. Stretching wide as if it had just been treated to a rigorous fuck machine session. You’re just a butt with a body attached. It’s how you view yourself, above all is tending to the needs of your ever hungry rear. The rest of your body is just a mode of transport, a means to an end. A rear end.

It feels like you’ve stood here for hours, but in reality it’s been no more than a minute. A minute was all it took for you to be repurposed as a literal butt boy. A mere sixty seconds for all your thoughts to be hollowed out; maybe you weren’t as smart as you thought, or maybe you secretly wanted this all along. Either way your head is now just a pretty picture to smile at before spinning you around.

The space in your head is about as empty as the hole between your pillowy cheeks, although only one has any hope of being filled up.

“Butt!” You hear yourself blurt out, like a child saying a naughty word. The sound echos down the dank alley.

Suddenly the butt opposite you turns away, his legs moving him towards you. A wordless instruction reaches your body to kneel and so you do, obediently. He turns back away, his beautiful ass only a few inches apart from your face. His joggers lower and his prize springs forth from it’s prison. He slowly backs his cheeks into your face until they eclipse your entire view. He continues until your head is pushed between his round globes with a blomf, encasing you, muffling the sound in your ears. There’s a mild tingle across your forehead/face.

You feel the pressure push against your sides. It makes sure your head is an appropriately vacuous vessel, squeezing out anything left. That little remnant that didn’t want to be butt brained drips away in no time, turned to drool and absorbed into the guys ass crack. This would be good for you; You needed to be made perfect, so you let the butt finish it’s work. A new set of instructions flow into you, into your ass. You feel your consciousness connect to the butt burying your face, assimilating and adding you as one of it’s own, making you part of something bigger. One of many.

The pressure on your head leaves your emptied mind subservient to the mass of tissue straining under you. It gives you a new identity.

I gave you a new identity.

BUTT BOY.

And you’re now ready for service. Butt. Boy. Ready to spread joy. To put it in the nicest way possible, you have a butt for a brain. It has been given full control, and it has one singular goal. You need to make more Butt Boys. It is that simple. It’s not a desire, it’s just something you have to do.

The cheeks spread open again and are unseated from your encased head, your broad smile still unflinching.

Something else is different though. A cold breeze brushes over your forehead. The hair on your head is nothing but a light dusting of what was there before, at most 1mm in length. It was one less thing to worry about, and one less thing to identify you with. It’s unsettling how much of your personality seemed to be stripped with it gone. The buzzed look certainly makes you appear more anonymous. Like a default custom character in a video game. Nothing made you stand out… well, aside from the obvious.

The ass in front of you is satisfied with your ‘adjustment’ and leads it’s body from the spot it once stood so patiently in. You continue to stare as the buttocks juggle erratically in the grey joggers as they leave the alleyway.

Your feet begin to move of their own volition. Movement is awkward, each step your balance is pulling you backward. You’re like a dumptruck trying to make a tight turn.

You are left in silence, aside from the clapping of your bouncy cheeks as you stumble forward to replace the previous occupant. You stand in the exact same spot, thighs pushed together, back straight. Now it is your turn to wait - like an animal for it’s prey, knowing that you cannot leave until you have passed on the gift to another man; ensuring that the cycle continues. The idea of causing someone else to go through the same process fills you with such pride.

It’s unclear how long you stand there, time in the alley doesn’t appear to operate within normal parameters. Like a crack in the world. You see your shadow projected onto a nearby wall, a straight line interrupted by an obscene vibrating speed bump. Doorframes could be your new biggest enemy.

You were desperate to see your reflection, from behind obviously. Most people take selfies of their face, the subject of your attention would be much further down.

You hear a voice echo from behind.

“Excuse me sir.”

One week later:

“Man, how much work did you have done on this, femboy? Unff. You make even my girlfriend look flat.” A towering voice booms down at you.

You’d picked up the jock in a club. He was relatively easy, it didn’t take much to end up back at his place. You stared at him with that horny, open mouthed duck face. But he wasn’t interested in what you had going on up there. It was remarkable how little men cared about how flagrantly airheaded you were once you flash your rear at them. It didn’t matter how ‘plastic’ or fake you so obviously were. The eye see’s what it wants.

He was clearly in the mood to let off steam, and one look of what you had on offer was all it took. You didn’t even need to say anything, which was good, as words were so hard to get right. For tonight, you were his; a light tap of your butt and he owned your body. A breathy ‘mhm’ confirming your obedience to him and his sizeable bulge. Your ass begins to moisten in preparation - it wanted him, in more ways than one.

He had told you his name, but you already forgot it; he soon would too. ‘Jocky’ was good enough for now.

Jocky was obnoxious in all the right ways, wearing his masculinity on his sleeve. That type made for the best, most severe adjustment.

“Love the buzzcut by the way femmy. Yeah…mhm. Very basic, it suits you.” He rubs a hand over the top of your head before running his fingers through his curly hair. It was a good thing he already liked the look.

*plap plap*

The strong man’s 7 inch cock thrusts in and out of your well used hole, pulling between your lubricated cheeks. Your buttocks squished against his member tightly, every bump rubbing across your hypersensitive skin. You were so hungry. He wasn’t the longest but he definitely had thickness on his side. You pant heavily as he has his way with you. Bent over his bed, facing away from him at a wall. He wasn’t as good at this as he thought, you would know, but it wouldn’t matter for long.

“Mmf. You’re a quiet one. Ah… I- I like that in a bottom. Makes a nice change from…hff. Always whining. Know your place. Fuck.” He continues to drunkenly rant into your ear. His deep, self-aggrandising voice quickly grating on you.

“Uuh. Take it all dumb slut.” You let him have his petty insults, it seemed to make him feel bigger, more in control. Evidently, he was obviously very self obsessed, dumb as you may be, even you could tell that much. The constant glances at his own muscles were enough of a giveaway. Eh. You’d seen better; the change will be a improvement.

He speeds up, sending shockwaves up your body and making your butt bounce enthusiastically.

“H…hey it’s real hot in here.” His voice shakes. “Umf. Maybe we should stop?” He puts his hand on your hip in an attempt to steady himself as he continues pumping you. You begin to push back into him, his dick pushing all the way in.

“Wh… what the fuck. My ass feels…mmm.” He groans loudly. You know how it feels. You can hear them rubbing together already.

His grip on your back weakens, the weight crashing into you softens. His body is like a deflating balloon, his diminishing height bringing him closer to the floor. The girth inside of you shrinks.

“Ahh. So heavy…damn. My-“

“Butt.” You tell him. A slight hint of boredom in your tone.

“Oh god, why does my head… so hard to think.” Right on cue, his smarts were being cleared out, in preparation for his ass to take over thinking duties. This part was your favourite; it wasn’t fair he had all that stuff while you felt so…blank. “Feels so good. Unnf.” It was too late for him to stop it, he’d soon be very happy. Happy, eager and ready to comply. “Shouldn’t though…” You take the lead, rocking back and forth along what’s left of his dwindling shaft. Your buttocks slap against his tightened chest.

*plap plap*

“Bouncy…hehe.” He laughs dimly. You can’t help but echo his giggle, it WAS a funny word. One of your favourites - top 5 at least, right after ‘jiggle’.

“Don’t wanna…fuck…b…but I can’t…but…but.” He stutters, like a scratched record.

“B…bu…Butt. Buuuutt.” His voice moans in realisation, mumbling the word over and over to himself. He shudders, squirting inside of you. It’s okay. It’s never enough to satisfy you.

His tiny cock slips out of your hole, dragging a small string of cum across your sensitive rear. That familiar feeling of emptiness sets back in. You get out from under him and assess your work. Turning to face him, you’re greeted by his broad smile and blank, lust-filled stare. His jockish face and body now heavily twinkified; those boorish muscles, gone. His cocky attitude, subdued. The bed creaks. You check on his oversized ass splayed beneath him, a rather drastic change from his previously flat posterior. Looking even more ridiculous with his shortened stature. The slight rubbery sheen was the cherry on top. Those plastic beach balls were made to twerk and put on a show. A vast improvement, he seems pleased by it too. His left hand is loosely fondling his new selling point.

“O…ohh.” A surprised squeak slips out from his mouth. It’s always a shock when they see where everything has gone.

You’re pretty sure he didn’t have much experience back there, if any at all. He’ll soon get the hang of it.

You know what comes next, what’s required of you - it’s instinctual at this point. You push him onto the bed and position yourself on top of him. You gradually begin to lower your huge rear over his head. You sit snugly down on his blushing face, shifting your weight a bit to get into a comfortable position. His gelled hair tickles against your skin, until it doesn’t…

He’ll make a cute Butt Boy.
