One of the privileges I'm claiming as mod is the chance to take all the Minerva/Rose prompts. So you'd be out of luck even if you didn't have to go out.

But I'm sorry to report that there isn't any prompt like the one you describe. There is, however, a Minerva/Ron/Rose threesome, and I'm taking it. So there. (The prompter also wants a side order of Harry/Scorpius. Eat your heart out.)
