You have to fight her on the same level

Sophie: "Let's think back... We both got our current forms by getting fucked, right? But Sofia got fucked twice, so she's like, on another level compared to me. That's why she can suck me dry in seconds and toss me about like a ragdoll. The obvious solution is to get fucked myself and ascend onto her level!"

Unfamiliar with male anatomy, at first you consider fitting your own cock inside yourself. This doesn't work at all, and in fact you almost manage to break your penis.

Sophie: "Whoooah-kay, that's right out! Where's that dildo the original Sophie was looking for?"

The same dildo you had used the night before, and which had likely led to the initial cloning incident. You discover it under the mattress, where you must've groggily stowed it away, like the heinously gross person that you are. Not wasting any time, you plant it onto an undamaged portion of the hardwood floor and start pumping yourself onto it.

The wonderful combination of having a clitoris and a prostate means you can orient yourself in just about any direction and still hit a whole bunch of nerve bundles. But only through intense internal muscle control and pinpoint accuracy are you able to stimulate both at once. The reward is imminent: the best orgasm of your life.

Your eyes light up as you feel pure power coursing through your body. Strength radiates outwards from your core, turning everything in its wake into superpowered, hyper-dense muscles. At first it feels like your dildo somehow disappears, but what really happens is that your muscles are now so strong that even while at rest, the rubbery plastic feels like air to you. The implement breaks apart unnoticed, having gallantly served its purpose.

Then, the growth spurt comes. Your head quickly reaches the ceiling, and you have the good mind to get outside before causing even more damage. Unlike Sofia who grew into every possible direction, you remain mostly muscular and sleek, though your boobs are proportionally maybe twice as voluminous as before. If you accidentally ran into a brick wall, it'd leave an imprint of your abs.

You tower clear over your house, but there's still one crucial matter: your loins. The entire inferno of pleasure that previously caressed your whole body has now coalesced into the tiny slip of skin onto which your male genitals are attached. Your cock swells as if it had previously been just a shriveled limp nub. Its new size is closer to a city bus than any human organs. Your testicles are each the size of a zord ball and probably weigh five tons each from the contained seed alone. Judging by the intense tingling sensation, they're producing incalculable amounts more with every passing second.

Now you're ready for Sofia. You look around but don't see her anywhere. However, following suspiciously footstep-shaped potholes in the concrete and a trail of extremely dehydrated men moaning in pleasure, you quickly catch up to Sofia, who's trying to reach her hand inside a gym.

Sofia: "Like, get with the program you guys! It'll totally be super awesome, you can ask any of the previous guyses."

Several of the men within hearing distance who had previously received head from Sofia weakly raise their hands in a thumbs-up motion. Before the gymgoes can decide whether to indugle the giant lady, you tackle Sofia, whose indomitable girth is easily countered by your indomitable strength. You fall onto the pavement on top of Sofia, whose pillow-soft body isn't nearly as delicate as you imagined, leaving her completely unharmed.

Sofia: "That's like, totally uncool. You're like, literally cockblocking me right now. I'm so gonna get you for this!"

Sophie: "You want cum? I've got the goods!"

You stand up, spread your legs and invitingly tap your balls, which gurgle hard enough to shatter a nearby display window. Sofia however is starting to get pissed, and for once isn't focused on sex.

Sofia: "Like, spare it, skank! Daddy's totally gonna hear about this!"

Sofia stumbles onto her feet and strangely grabs a phone from somewhere, despite beind nude. It doesn't look like your regular phone either: it's a flip phone with a solid gold casing and a pink heart-shaped keychain. She picks a number from the names list.

Sofia: "Daddy, there's some uppity bitch here who needs to like, learn a lesson. Can you like, send some backup? Love you! Buh-bye!"

She's calling your dad?! Hopefully that's just some kind of a magical construct that comes with being a hyper bimbo, and not your real dad. That'd be hella embarassing. You mutually disowned each other after your parents found out that you're bi.

Sooner than you expected, the phone call starts to have results. You see a jet airplane fly above, dropping a crate with a parachute. It floats down so gently that you could easily intercept it, but you're actually kind of interested in seeing where this is going, and honestly Sofia is going to lose this battle so badly that you'll allow her the illusory courtesy to even the odds.

The crate opens by itself upon touching the ground, and in a sudden blinding flash, Sofia is manning a ginormous gold-plated battle tank that reads 'Daddy's Little Girl' on the side with diamond-studded letters.

You're less than impressed. You waltz up to the tank's cannon and wordlessly insert your cock into the tank's barrel.

Sofia: "H-hey! That's like, totally cheating!"

You grab onto the barrel with two hands and start to thrust, the metal deforming under your grip. Sofia helplessly tries to actuate every button and lever in the cockpit, but can't get anything to work - your precum has already managed to jam every possible system in the vehicle. In only a few seconds you spurt out. The barrel practically turns spherical upon the sudden influx of sperm, and no less than a hundredth of a second later the rest of the tank blows up into shimmering scrap metal. Miraculously, there's only superficial damage to the adjoining houses and businesses.

Sofia: "Ki-y-aaah!"

Sofia herself, despite her mass, flies off in a clean arc down the street and craters the asphalt upon landing. You tear off the remains of the tank's barrel off your cock and stride towards Sofia, whose legs have been left dangling invitingly open. That's not a part of your plan though - your target is the mouth.

Sofia: "Need, cum... Reserves... like, totally... dangerously... low..."

Helpfully you stick your dick down her comparatively tiny mouth, which accommodates your width with commendable fluidity. Even though you blasted only seconds ago, your loins are still itching for release. You start pumping continually faster, reaching supersonic speeds before your balls tighten and release a biblical flood down Sofia's trachea.

Your ejaculation sounds like a burst Hoover dam flood gate, and the vibrations alone are enough to cause more damage than that tank explosion, even while muffled by Sofia's soft and malleable body. Most windows break in a two block radius, and at least a few apartment buildings collapse.

After almost five minutes of continusly cumming into Sofia, she's no closer to being full. By now she must have a several lakes worth of semen inside of her. Where is it all going? How is she not dead despite not having her esophagus blocked by your cock for all this time? Sofia's definitely alive - she's still moaning in pleasure and her eyes occasionally focus back into yours.

People are starting to evacuate the city, due to the earthquake that you're causing. Ten minutes in and Sofia feebly tries to leglock you, but her thighs are far too thick to reach. Even your own body is starting to feel the strain from the forces at play.

After a full hour, you're sure her body should contain a full ocean's worth of cum, but it doesn't show outwardly in any way. You decide to stop for now, and retract yourself from Sofia's mouth. She gasps for breath, seemingly no worse for wear.

Sofia: "Ohmigosh, you're like, such a stud! I think I'm... I'm gonna..."

You take a few steps back. At first you fear that she's going to explode, but no. The opposite, in fact. Her body starts to fold onto itself. The amount of cum inside of her was compressed into a small enough of a radius to form a black hole!

Sophie: "Oh, fuck my life!"

You make a run for it. Only your superhuman legs could propel you away fast enough to escape it in time. You look back and see the neighborhood being swallowed by the black hole. No idea where you could possibly escape to, but you decide to just keep running for as long as possible. You have a penchant of making stuff happen even during the most **** of situations.

Then you have a brilliant idea. The only way to get rid of the black hole is to propel it into outer space. Your idea of course isn't even closely analogous with any existing laws of physics, but thankfully neither is anything else that has happened today. Besides, you're about to face planetary-level extinction, so might as well go all out.

You jump up into the sky, just hard enough to barely avoid escape velocity. You happen to have a doctorate in geology, and know that your city happens to be located on top of the Juan de Fuca microplate's subduction zone - your thesis was written on the subject, and you moved here to study it in person. You make a few mid-air adjustments to your trajectory and aim directly into the ocean, on the other edge of the continental plate.

As you approach the ocean you begin to spin around rapidly in place to create a tornado - this is to displace as much water from around your target as possible. You clear the surface easily without even getting your hair wet, and manage to strike the stony surface of the ocean floor, barely slowing down at all. The entire Juan de Fuca plate gets flipped over like a boat. You become plunged into the molten mantle of the Earth, while your home city, with Sofia and her black hole included, get tossed into space with a lever motion.

Sad to say that while you managed to save the planet, it wasn't enough to save the human race. Your stunt ravaged the whole planet's geology, causing massive volcanic eruptions, earthquakes and tsunamis all over the planet. Only few small enclaves living in unusually geologically stable areas manage to hold out, and they too will likely die out in a few years due to volcanic ash blanketing the atmosphere and blocking all sunlight, making agriculture impossible.

As a superhuman, being immersed in molten lava doesn't phase you. However, you correctly figure out that the survivors might not exactly appreciate your actions, so you decide to remain there for a few centuries. Maybe by then, society has forgotten what the cause of this apocalypse was, and you can emerge from some volcano pretending to be a Fire Goddess and live like a queen.
