Miles tall

It's difficult getting an accurate sense of scale, what with all this mist in your way. Ah, nevermind, that's not mist. Your head is just literally in the clouds. Mist is practically just a cloud that's close to the ground though, but technicalities like that are irrelevant to you now because you're miles tall.

The Burj Khalifa would maybe just reach to your knees. Another convenient point of measure for that record-breaking building is that your cock is longer than it. The city under your 1500 feet long feet is about to find out the true meaning of 'fun-sized'.

You look closer, down to a tiny patch of developed ground which you're sure used to be your neighbourhood. A single drip of spunk from the tip of your protruding prick has flooded it - the entirety of your previous life. You've now been freed from the constraints of modern life and handed the reins to thoroughly disassemble modern living in its entirety for everyone else as well. Your home city will do nicely as a start.

With a few sparse steps, you walk onto the outskirts of the city, sit down, and lean forwards that your penis is horizontal to the ground. Then, with a few determined tugs of your cockflesh, you once again become an apocalyptic messy cumspout. The few ounces of focus that you retain allow you to increase the desctruction even further by swinging your implement back and forth, leaving a quarter of the city mushed into rubble underneath it, and the rest drowned in your girlspunk.

Sophie: "F-f-ffff... hwaaa... That was so much fun! And I didn't grow either - I must've attained peak proportions!"

You were able to somehow sense the feelings of everyone in the city right before their deaths. Surprisingly, the overwhelming majority of it was relief: in fact, the masses had been anxious and worrysome for years now, some even decades. They felt having lived on borrowed time, on borrowed standard of living, and on a high-interest load which they had no way of paying back. Having you wipe out the city also meant destroying this debt, and all of their fears with them. No more toil, no more corruption, no more crime, suffering and mental illness. Only the purifying white flash of **** in your angelic form.

Or perhaps you're projecting your own feelings in a way of justifying to yourself how good it felt to destroy a city with your dick. In either case, you're going to keep wrecking to your heart's content.

Sophie: "I know there's another city right around here somewhere..."

You move on down the coast, leaving behind hundred-feet deep footprints into the bedrock in your wake. When the military gets wind of your ongoings, they're not going to have much trouble tracking you - but you couldn't care less about that, of course.

The next city has an exotic feature: a nearby active volcano!

Sophie: "Ooh, I need to try this! Better test it with just my finger first though, just in case..."

You dip your forefinger into the pool of molten lava. It feels so warm and fuzzy, like a heat pillow. The next obvious step is to stick your entire jutting ramrod into the poor, virginal volcano and start pumping it like the heated onahole that it is. A volcano - one of the most cataclysmic and uncontrollable of natural forces, is merely a temporary little toy for you.

You cum harder than ever before, and with more volume than you thought would be possible. Cum just keeps coming, and coming... your girth nearly doubles from the gargantuan stream of spunk in your seminal tract, utterly decimating the volcano. Soon, you creampieing the Earth begins to show signs on your surroundings. For instance, the ground bulges out from the oceans of cum being poured into it, before cracking and bursting. The city is immersed in cum-laden lava within seconds.

Sophie: "That was... hot, lol. Huh. You know, all this destruction feels pretty damn nice, but like, there are a lot of cities in the world. This is gonna take a long-ass while unless I come up with something."
