He wants “Dash and Daring Do doing some roleplay, with Dash as the villain who captured Daring… and is way too enthusiastic about her role.”
So here’s Rainbow Dash as the villain for her roleplay session with Daring Do. She took a page from Daring’s novels and a femme Doctor Caballeron cosplay. The pose was important here. I needed to have a at least one arm giving a rope a good strong pull. The rope Dash is pulling on, that’s the one attached to Daring’s wrists. And by pulling on it is causing the rope to dig into Daring crotch. That seems to be a good way to make “Daring Do’s bonds a bit too tight.”
