[M4F] Dominant tiny and submissive giantesses

Hi, the title pretty well sums up what I'm seeking. I prefer to take some time before jumping into the narrative to learn what are our shared mutual interests. I also enjoy doing a bit of world building together; coming up with a scenario that's going to maximize our mutual fulfillment. But the foundation of what I'm looking seems to invert what tends to be the usual expectations for the pairing of dominance and submission with extreme size differences. Usually, the larger one is the more dominant character. This of course makes sense if the foundation for power exchange is focused on the physical imbalance. It's probably how things might likely play out in reality. However, since we're already abandoning reality for an existence filled with giants, giantesses, and tiny people, why not also indulge in a reversal of expected D/s roles?

The particular flavor of dominance and submission I find most validating involves mutual fulfillment through a non-egalitarian imbalance of authority. I find that the more powerful a submissive, the more capable they are, the more strength they're able to hand over to their dominant, the more that options that facilitates for the dominant to utilize for their shared desires. So, with a submissive giantess, there's so much potential there for a deep exchange of immense power. A lot of submissives love catering to their dominant's pleasure. A subservient, towering, powerful giantess could serve, comfort, pamper, and please abundantly the one in whose trust they want to place their control. Just imagine with how much ease you can indulge, spoil, and gratify a dominant you can hold in your hand... or other places.

I don't have any one specific narrative I want to pursue. I'd love to hear your ideas and see how we can build something truly arousing together. I've an interest in exploring scenarios with Giantesses, mini-giantesses, Amazons; or as a shrunken or tiny man. We can pursue sword and sorcery fantasy, sci-fi, modern, historic, or futuristic settings. The size difference can simply be an alternate reality where it's commonplace, or the result of magic or science.

I'm open to either chat or messages here on Reddit. I prefer first person narratives with a couple sentences or paragraphs in each response. I'm not impatient when it comes to waiting for responses. I understand there's real life obligations that may prevent either or both of us from responding as frequently as we'd like.

Below are some narrative scenario prompts I have in mind. But again, you're welcome to suggest anything that you may be wanting to explore:

• Human House pet to Giantess Alien: In the not-too-distant future earth's skies darkened as massive ships began eclipsing the sun over the various capitals of the world. Not only did humanity learn we're not alone in the universe, we learned that particular race is woefully small and powerless in comparison to what's out there. Our world and it's inhabitants were viewed as an adorable little anomaly. The ruling galactic alliance enacted protections turning the earth into preserve of sorts; classifying humans as exotic pets. As news of these captivating little creatures spread throughout the cosmos, scores of people were abducted. Now, with the regulations in place to preserve a now endangered human species, you've had to save up and impatiently endure your time on a waiting list. But, the day is finally here and you've qualified for a little human of your very own to love and spoil as your most treasured companion. Your home world is far from Earth, but your compatible biology and atmosphere are the only reasons you ever even were approved through the initial screening process. Looking out one of the windows of your transport the little blue green sphere is growing larger as your shuttle prepares to dock and land. Sitting at the supervisor's desk in the "Adoption Center" aboard the space station hovering above Earth's atmosphere you begin to wonder. Will you get to go down on the planet and see their little cities and all of them scurrying about? Will you get to choose your delightful darling? Or were you already assigned one and I'm already aboard the station in a carrying case waiting for you?
• A Submissive Scientific Mishap: We've worked together in a lab for a little over a year. We could both be grad students, or a supervisor and intern. You're the quiet type, shy, reserved, highly intelligent and harboring an intense crush for me. The desire to let me know how you feel has only grown more powerful now that we're working long hours alone together late at night on a government contracted project. If only I weren't so intimidating, you could act on your urges to show me just how pleasing an force you could be in my life. Your mind drifts off in daydreams of our life together, when you realize the safety protocols on the experimental size shifting technology misfires. In this scenario you could either shrink me, or you're in the danger zone and grow yourself. This could all have been an accident, or maybe some part of you meant to dramatically shift the size imbalance in your favor so you could finally feel strong enough to profess and act on your feelings.
• Fantasy World Domesticated Amazon or Mini-Giantess: We live in sword and sorcery reality of magic and mythical creatures. It's a word where normal sized humans are by far the majority population. But races of fairies, sprites, orcs, amazons, and giantesses of all sizes also exist and are viewed as chattel. You were captured in the wild and are to be sold at auction to be domesticated as a beast of burden or sources of pleasure. I stroll through the holding pens and cages at the auction grounds. When I stop at your pen as you're chained up, what do I see?
• Complete Magical Submission: We're already in an established and fulfilling D/s dynamic. While window shopping through a row of antique shops you find old manuscript in an oddities and curiosities shop. Supposedly it's a magic spell book with an incantation that could allow you to give someone else such complete control of your body, that even your size and strength could be handed over. The idea so piques your interest, to so completely hand over yourself to me immediately excites you to a surprising intensity. You give me the book later that night while on your knees and whisper a lustful plea, "Please Sir, grow me to whatever size you think would be most useful to you".
• Personal Assistant to the Reclusive Billionaire: This new position was the chance of a lifetime. You couldn't believe after all the interviews and assessments that you'd be offered the job as the personal assistant to one of the wealthiest and most influential men in the world. A job like this could be a springboard to so many professional opportunities. The only thing strange about the situation is the person under whom you'll now be working directly, has never been seen in public. There's plenty of urban legends online speculating as to why. After signing a tall stack of paperwork, including an extensive NDA, you're finally invited into his office. Set along the far wall you see a large expensive looking professional desk. Then, your eyebrow cocks and your head tilts slightly as you see a much smaller doll sized version of that same desk at the center of the large desk. And, seated, working at the tiniest computer you could never even have imagined possible, was your new boss.
