basically a female pink plastic version of clayface from batman. I cant think of a motivation that would end in what i was going to try to make “girl on girl sexytimes” Ive been wracking my brain thinking about it but i cant find a good rationalization... how would you get bitches is you were a plus sized pink shapeshifter metahuman?
This is SIMPLE. She's a lesbian, and wants to have a GF. Some lesbians, like some hetero men, are into the thick girls. She goes to a club, meets one of them, they hit it off, one thing leads to another... Now as for her actual character motivations, I'm less help there, but there's always the usual five, money, power, revenge, fame, and love, pick one and build on it...
Well, I'm assuming you don't want to do the non-con Stockholm route... cause that answers most of your questions... She's got powers, right? How about she rescues some broad? She's shapeshifted, she reveals herself, super embarrassed, expecting the worst reaction... and her new friend is into it! Giggling, cute, she's fascinated and curious. Or, her new friend is weirded out. Runs away. Our hero is upset, but her save-ee comes back, later. Ashamed, and confused. And... a little fascinated, and curious. That's rescue. There could also be stalking. Let's say our hero develops a crush on some chick. Finds out what her crush likes, and being a shapeshifter, tries to become what her crush likes. 'Accidentally' bumps into her, tries to get into her pants, and at some point along the way things go awry and you can work in some Aesop about, like, being yourself. And maybe another Aesop about how stalking is bad, m'kay? Or, no moral lessons. As for 'motivation' - very simply our pink shapeshifter can be lonely. She's one of a kind, she's maybe hunted, she's got no one to share with... And, you can write in some odd biological imperatives, or psychological imperatives. She's a pink damn shapeshifter that you're writing from the ground up - you can assign her any physical or psychological properties you want.
OK, you want details? Let me give you an outline, building on what Loeman said. {Shapshifter} wakes up in an abandoned lab, no idea where she is or why she's there. (Knowing who she is optional, but recommended, the total amnesia thing is rare and done to death. For the rest of the outline, we will assume she remembers who she is, just not how she got there. Kinda like a 'The Hangover' situation.) She Shapeshifts instinctively to get out of her cell, finds a bathroom, takes a piss, and looks in the mirror. Was not hot pink before and not weighing in at 200#s, kinda freaks out, breaks the mirror. Winds her way through the lab to an open door. Fight with the guard dog must be avoided, subverted, or overcome using transformation powers. Gets outside, it's after dark and the streetlights are on. Is in a deserted section of some old industrial town, no one's around. Wanders around a while till she comes on a mugging, only people she's seen this whole time. Here's the first big branch, she can either intervene directly or indirectly, basically you're choosing heroine or stalker route. (I leave the stalker one up to you because stalking is not my thing and I don't like even outlining it, plus a friend just pointed out it's really damaging to people to have it glorified.) If you chose to intervene directly you have three options to how to do so, based on her powerset. (You know that: I don't.) One leads to the woman staying and being curious, like Loeman said, one to her running away and {Shapshifter} having to take shelter in an unlocked car for the night but the rescue-ie coming back in the morning, (It's her car by the way...), and the third to a bad end. (Got to have a few of those in any good CHYOA story.) Think that's enough to start on?
