If you ever do decide to add her to D.I.E.T., I have an idea that I think would make a really good storyline.
The main character hooks up with her — she’s a college girl who likes to sleep around because she loves getting as much pleasure as possible. That’s why she keeps herself in such good shape: so lots of men want to please her. But she wants to hook up with the main character again, which is out of character for her — she’s more of a one-night-stand type of girl. But the main character really went above and beyond, and she wanted more.
The main character introduces her to feederism by first bringing food into the bedroom. Things progress from there e.g funnel feeding huge stuffings force feeding calorie challenges, et cetera. She’s kinky and likes being lightly degraded. The main character starts saying things like, “I’m gonna make you into my personal big fat slut,” which really gets her going. She falls in love with feederism because it gives her not only the sexual pleasure she was already obsessed with, but also the added pleasure of overindulgence and fattening foods which should never really experienced being so obsessed with keeping herself in good shape.
As she starts gaining weight, fewer guys are interested in sleeping with her, so she spends more time with the main character. They become really close because they’re just two nice, honest people who love a bit of kinky sexual fun.
She ends up becoming a weight gain model, with the main character as her feeder.
