Use mountains to train with

What was that about being as strong as continental drift? Well, time to test out that assesment! The rockies are only a few hundred short miles away, a distance of only a few footstrokes from your Divine legs. You stop in a chasm somewhere in Western Wyoming, stopping on a dime from your literal lightning-speeds.

Sophie: "Now this looks more like it! Mother Nature will provide where human engineering fails."

Proudly and without noticeable effort, you begin to pummel your way through the sheer mountainside with your fists, carving an entry into the depths of the mountain. Having reached the approximate middle of it, you raise your arms to the top of your passageway and begin to push. At first, the rock gives away easily, but you recognize that this is only because the integrity of the stone can't withstand the weight of the mountain.

Sophie: "Darn it to hell, mountains are a lot more unwieldy than I anticipated. No worries though, a Goddess will always find a solution."

You increase your speed once more, this time to even more ludicrous extents. Fire and sparks of electricity come flying from your feet as you begin to race around in an ever-largening circle, pulverizing the solid stone as easily as one would sweep dust off a table. In the blink of an eye, the entire segment of the mountain has disappeared into thin air, leaving the rest of the monolithic edifice to crash down upon your expecting arms.

And whaddya know, it feels heavy!

Sophie: "Haha! Yes, this is perfect! A good billion tons of mass feels like a normal loaded barbell."

You revel in the feeling of a normal workout, doing bench presses, curls, and pushups while encumbered by the mountain. This would be the first time in your life you've done actual, full pushups instead of keeping your knees on the ground!

After thirty minutes of workout you're sweating, and one might say, almost tired. You drill a hole straight down and set the mountain back on its basin, and then tunnel out yourself. This way you can come back later to workout more, if need be.

Sophie: "That was fun! How's about it girls, didcha enjoy yourselves too, huh?"

You lovingly smootch your biceps, which glisten with droplets of sweat in the midday sun, and seem to practically glow with power. Each digit in both of your hands, strong enough to lift a whole city if you so desired... it's simply too much to handle! You have to jill off right now or your mind will be too fogged up by arousal to do anything.

You lay down on your back on the soft granite and start twiddling your insides with two fingers. Shudders of delight run through your body. The body hairs on your skin rise up and gouge tiny furrows into the granite. You don't pay it any mind - the resistance from the solid stone is insignificant to you.

Sophie: "Gggggawd! This feels so good, so fucking raw! It's like I'd been masturbating with mittens on my entire life... How have I lived without these Godly muscles?"

With a body like this, bringing yourself to an orgasm is a trivial matter. The real issue is delaying it, so that you can adequately savor the moment. You let your legs thrash around and quiver in ecstacy, and let out the most indecent moans and screams, knowing that nobody will hear it, even though your powerful voice echoes for a dozen miles through the mountainous landscape.

You've reached the pinnacle. If you were a regular mortal, you'd've cummed twenty times by now. You're balanced on your upper back and toes, holding a perfect arch, maintaining a steady blast beat rhythm to your twiddling. Then you slow down, focusing everything in your loins, and then speed up one last time, using your hypersonic speed to ravage your clit.

In the midst of your orgasm, your indestructible, super-muscled ass crashes down onto the exposed bedrock, instantly pulverizing it for miles down. All the mountains around you crumble into sinkholes as the previously steady granite is turned into dust in an instant. You're a bit bummed about losing your mountain weight, but it's safe to say that destroying a whole mountain range gives you a feeling of power.

As you get up to look around, it occurs to you that this devastation was a bit more comprehensive that you initially assumed. Forests are downed for hundreds of miles around. In fact, you can't even find the edge of it. Cities have crumbled too, at least all the way up to Los Angeles. Or you think it used to be Los Angeles, because every discernible land mark has been ruined, and even the seas have drained into intercontinental cracks.

You check the East Coast. Everything's collapsed there too. How hard did you slam your ass down back there? Did you really destroy a whole hemisphere in a single move?

No, it gets worse. There don't seem to be signs of civilization anywhere on Earth. Only rubble remains, with the occasional corpses.

Sophie: "Darnit. I've just gone and turned the entire Earth's crust into powder, haven't I? That's no bueno."

With a hand on your chin, you consider things for a moment.

Sophie: "Welp. Nothing left to rescue. Now the only thing left to do is destroy the planet for reals so there aren't any loose ends."
