"Mmnf~... hhnf~... nngh~..."
She was all you could hear. All you could see. Even while she was kneeling before you, bouncing on her own legs, your eyes were glued to her chest. Her massive, cavernous, overexposed, overdeveloped chest, which was currently stretching your best friend's tank top to its absolute limit.
"Unff~... haah~... b-bigger~..."
Her mind and body were both on autopilot, as her hands reached up to cup her own chest. The same one that was now popping seams off of her tank top, and was threatening to completely burst out of her shirt without any way of stopping its own growth.
But as you kept staring, completely transfixed on your best friend's growth, something seemed to click inside of your girlfriend's mind, and she giggled.
"Mmnf~... fuck, you must be just as addicted to these things as I am, huh babe~?"
The question came at you point blank, leaving you no chance to respond before she shrugged her tank top up and over her breasts, letting them flop out in a majestic display of their size, before she began bouncing once more, titnotizing both you and herself even deeper.
"There we go~. Now there is nothing in the way of my breasts~. My tits~. My marvelous, magnificent, mesmerizing, mind-melting mammaries~. My gargantuan growing lumps of goonermeat meant to be worshipped and served~. My BOOBS~."
Abruptly, another surge of titflesh occurred, as cup size after cup size was piled onto her already massive bosom. Then, another surge happened. And another. And another. Already they were beginning to encroach upon your kneeling form, taking up more and more space, yet your best friend continued smiling. Continued bouncing. Continued touting the glories of her own gains.
"My boobs are going to crush everything, you know~?"
She asked that so calmly, like asking for you to hand her a bag of chips, that your mind just accepted it as fact. Her breasts are going to crush you. They are going to crush EVERYTHING, and there is nothing you can do to stop them.
"Mmnf~, you're still staring~. Not that I blame you. My tits are the only good thing about me. In fact, my tits may as well be my entire identity at this point. Who cares about the girl attached to them? I don't. I just care about my tits. My growing tits. My crushing tits. My soon-to-be-apocalyptic tits. The same tits that you always stared at when you thought I wasn't looking~."
Another giggle escaped her, and her tits reached you, pushing you back, pushing you towards the wall of your apartment.
"But I knew. I always knew. How could I not? My tits were made to be stared at. And every time you stared at them, you fed them. Made them bigger. Hungrier. More apocalyptic than ever before~."
Your back hit the wall, and her tits continued to surge forward, engulfing you in flesh, crushing you in their pillowy softness.
"Now? They get to become the apocalypse you wanted. The apocalypse this whole world wanted. And you get a front row seat to the end~."
The cracking of drywall signaled the end of the apartment's lifespan. In an instant, her tits burst through, and continued their expanse. Nothing could stop them. Nothing would stop them. They would burst through wall after wall, taking up more and more room, until the whole apartment building came crumbling down.
And as the apartment building collapsed, your best friend's tits protected you from falling to your demise. They grew around you, shielding you, keeping you alive and warm and comfortable as they continued their exponential expansion.
"More. More! My tits are going to keep on growing even more~!"
Your best friend's announcement came out as a manic declaration of the obvious, as her tits began usurping buildings, crushing and steamrolling over them, decimating anyone unfortunate enough to be caught beneath their mass. You were the only one spared. You, and you alone, would bear witness to this armageddon. To her armageddon.
"Fuck~! I can feel them gaining speed~! So many eyes staring at me~! So much attention~! So much GROWTH~!"
At the climax of her latest orgasm, her tits wrapped around and completely decimated a skyscraper, before she giggled, and her tits began steamrolling the downtown area, flattening it into dust beneath her bust.
"I am the apocalypse~! I am the biggest~! I am my tits~! And my tits want MORE~!"
By the time her tits were crushing the entirety of your home city, you finally blacked out, unable to stay conscious long enough to watch her outgrow the state, then the country, and then the planet.
But at least you had the best seat in the house to the end of the world...
