When Kat signs up for the sexual training version of housing, she doesn't think much of it. It's cheaper, in a nicer dorm, and she'll still be living with another woman. And she figures it'll be just extra sex ed or something like it--probably some weird subsidized program to teach better sexual education.
And it'll be nice to learn more about sex. As a virgin from a place where the sex education boils down to "don't" she already feels behind.

Mira knows from the start that her roommate will be fun. Naive as anything, no idea what's going on--clay to be shaped as Mira wants. And here she can do so with the full backing of the university. As long as she plays her cards right, Kat is hers to play with for as long as she wants.
Kat's panties go first, and the replacements. Mira offers her alternatives, but Kat has to ask every day for Mira to give her one--they're Mira's, after all.
Some panties are crotchless, others barely-there thongs, and still others she covers in arousal gel before she hands them over, so Kat spends the day wet and sensitive with no idea why.
Mira masturbates in front of her, openly, not bothering to feign shame about it. She leaves things unwashed strategically so their room always smells of sex.
Eventually she starts playing inductions at night, "meditation tapes" that are really about building mindless wet need. Kat starts waking up to wet dreams, and then she starts waking up with her fingers between her legs, rubbing desperately.
The inductions are all about edging, though, not cumming, and Mira makes sure to interrupt any possible opportunity for Kat to cum, leaving her more and more desperate.
Finally, Kat comes to Mira for help cumming. She doesn't even know what it feels like, she explains, much less how to do it. Mira promises to help.
And that's when the fun begins.
Because Mira shows Kat how to cum--then punishes her for it. Every orgasm gets a spanking or a slapped clit. If she cums in a wet dream, she needs to spend the next night tied up, to avoid that happening again.
And then she has Kat ruin--and rewards her for it. Praise, or a treat, like she's training a pet. A ruin becomes good cumming while a true orgasm becomes bad cumming.
So with every day and every ruin, Kat's need only grows, and so does Mari's control over her.
