Thanks for the story, PolytheneWrappedMe! You've got quite an interesting idea here. A "fool-proof plan" indeed... as if! I get the sneaking suspicion that things won't end up according to plan by the time part 2 rolls around. Or at least, not according to YOUR plan. I guess it's just a matter of figuring out whether Margy is doing this to indulge your desires, or if she finds such a fetish to be repulsive and is using them as a convenient excuse to be rid of you. Or maybe she herself hasn't decided yet?
I always feel a bit torn on the inclusion of literal "magic" in such stories, but it certainly seems worthwhile if it can create scenarios like this one which wouldn't be possible otherwise. I'm looking forward to seeing where it all goes.
