By having sex

You position yourselves such that you're facing eachothers, Earth between your stomachs. Gravity on the planet's surface has weakened considerably, causing tremendous earthquakes globally, and decimating any infrastructure left on other continents. At this size, even the slightest actions you partake in will have humongous consequences.

You decide to properly put this tiny beachball to shame. Steven rubbing his aching erection against the marbe-smooth surface constitutes as a 14 Richter earthquake, and you resting your pillowy breasts on it smothers the entire continent of Asia. Steven then tries to blow a raspberry against the Pacific, only to accidentally pierce the Earth's mantle a thousand miles down.

Sophie: "I think it's time to let the thing out of its misery, don't you think?"

Steven: "Oh, now you wanna be humane? Phew. Where's that dirty girl who thought to squish a city against my balls to make me snuff another one out with my cum?"

Sophie: "You're right! Sorry, I had no idea what I was thinking..."

You lean in very, very close, lips almost against the ground, and inhale sharply. Then you laugh heartily.

Steven: "...You did not..."

Sophie: "Oh, but I did! The entire Earth's atmosphere, wasted on my super-duper lungs! They'll all suffocate in a few minutes at most."

Steven: "Why?"

You propel yourself along the ball's surface to get up close and within kissing distance.

Sophie: "So you'd hurry up and fuck me raw, you massive hunk!"

The two of you engage, intertwine and interlock. Earth, but a tiny toy in this tumultous titan tumble, probably gets smacked between your abs slapping against one another at some point. It's just a stupid little planet, who cares anymore?

Steven fills you up to the rim, his overabundant semen spilling out. Just an infinitesimal trickle of his cum is enough to smother the Sun - and you're taking it in heaps, inflating a small bump on your stomach despite the fact that you're still growing, and at an accelerated rate at that.

After what feels like hours, you and Steven finally begin to relax. Opening your eyes from their blissful half-waking state reveal that wherever you are, your surroundings are caked with spunk. Everywhere you look is white, as opposed to the expected black.

Sophie: "...The hell just happened?"

Steven snaps out of his caressing embrace and opens his eyes as well.

Steven: "Huh. Weird. It's sort of like space itself's gone all sticky and white with my cum."

Sophie: "Maybe... maybe you came so hard that your spunk washed away the fabric of space-time?"

Steven: "That sounds impossible."

You turn to look at Steven, with an expression of mild disbelief and amusement.

Sophie: "What, more impossible than growing to a giantess and wrecking the solar system in a fit of passion?"

Steven: "Yea. I mean breaking the laws of energy conservation is one thing, but..."

Sophie: "But what?"

It occurs to Steven that in a system which adheres to formal logic, a single inconsistency can be used to derive further impossible results of an arbitrary amount and quality. Thus, no two impossible events can be considered 'more impossible' than the other. So after you two broke the laws of physics earlier today, literally anything was possible.

Steven: "...Ah forget it."

You settle down once again in each others arms, watching the universe quietly erode itself away.
