I'm not sure if its a story or gameplay suggestion, but a way to keep a low acceptance run while ending up super girly. Also, I'm a sucker for lactation, and I could see it becoming a secret menu type thing if you keep leaking through your uniform.
yeah, basically never quite fully accepting her changes even as everyone around her does stuff like using her submissive nature to make sure she doesn't feel confident enough to resist. In short, compliant but resentful, and every so shy and blushy about it. you know, like go back to wearing guy clothes and you can end up restricted from wearing pants.
