[M4F] My beautiful, unstable Gem partner (Steven Universe)
Hello everyone, I hope you’re all well and horny!
I'm wanting to do a roleplay themed around the show Steven Universe where you’d play a human who somehow gets an unstable gem planted into them.
“What’s an unstable gem?” Well I’m glad you asked! Basically it means that your gem can become any gem pretty much at random. one minute you’re a beautiful Pearl with a thin body and almost no curves to speak of. Another time you’re a tall Quartz with tons of curves and muscles. Then you’re a massive Diamond, with no way of knowing when or where you’ll transform (or what into) other than an odd sensation for a few minutes prior to the event, which doesn’t give you much time to get somewhere private
Meanwhile I’d be playing your partner, boyfriend, husband, fiancé…you get the idea. I’d like some story here as well, with both of us having to deal with the quirks that come with your new body. As well as the world around us, I imagine quite a few people would have things to say about your changes.
I imagine that eventually you’d learn about your new life as a Gem. learning how to shape shift, which will come in especially handy if you learn how to shapeshift clothes onto yourself, figuring out that we don’t have to worry too much since most major injuries will just lead to you poofing and coming back a while later. Perhaps even learning how to change into different gems at will, though that last one is definitely optional.
I would like to keep our characters OC, personally I’m just not sure how canon characters would fit as partners in this. Though I may include some when I’m playing as the GM in this. I imagine some knowledge of the show will still be required to play this though
