I know you don't normally do shrinking stuff, but I like your size theft stuff a lot, and I wonder just how far you would take it if given the opportunity
So, fun fact about me, I actually love shrinking/micro stuff. I usually couch it in the context of size theft because expansion is, like, my main kink, but I do like it independently as well! Just being tiny/shrunk and the big world looms high above you, seeing everything from a new perspective.
Just picture it. The 'ground' under you is not only soft and a pale pink, but warm. You can remember on a recent night, a cold night, diving under the covers in search of that warmth, but now it surrounds you on all sides, rising up from beneath your feet. The air is humid, too, and thick with the familiar, now overwhelming scent of her. You're not the only one breathing, though, and the ground beneath your feet rises and falls in a steady rhythm, occasionally shifting with the pulsing of a heart that you know to be many times your own size.
It's hard to focus on what's beneath your feet when, though, when rising above you on either side is a pair of absolutely enormous breasts. The term "mountainous" has never felt more appropriate, the walls of her cleavage soaring high above your head, having to crane your neck to see the point where they curve out of your line of sight, knowing that they keep going up beyond that, too. That pulsing you feel beneath your feet makes the walls of flesh on either side of you ripple as well, a wave traveling along their soft surface. They make her chest feel even more foreign as, before you were shrunk down to be this small, they mountains were just little hills, capped with cute nipples. You reach out, placing your tiny hand against the side of it. It's soft and your hand sinks in slightly from the pressure, but your small stature means that you can't exert nearly the kind of pressure you used to. You swallow when you realize that 99% of your body, the size you used to have, is in the colossal tits that rise on either side of you.
When you eventually manage to pull your attention away from the staggeringly huge breasts, you finally see her. She's looking down at you with a grin on her face. For the first time, you feel the full effect of just how small you are. You know that face. You know those shining eyes and that bright smile. You've held those cheeks in your hands. And now she's looking down at you, more like a part of the landscape than a person. You're not even entirely sure that she can see you, surely just a tiny speck against her skin. Even a small giggle from her feels like rolling thunder, the sound not only coming from her lips, but vibrating from her chest underneath you. The sudden shift of her ribs is enough to knock you onto your feet, feeling smaller than ever.
A shadow moves overhead, something big enough to block out the sun. It takes a second to realize that it's her hand, the hand you used to hold in yours as a tiny little thing now reaching for you. You're helpless as she pinches you between her thumb and her forefinger, the air roaring in your ears as she whisks you into the air with no effort at all. The tits that dominated your entire body now lay far beneath your feet, giving you a view of just how massive they are. Her nipples alone must be taller than you are! You're not sure you like the mischievous gleam in her eye, but at this point, there isn't anything you can do about it.
