Dumb idea · 1:34pm Jun 1st, 2017
An idea for a story just popped into my head. I doubt I'd write it, so I'll just spit it out here in case anyone else is interested.
Mature content warning. Applejack and Rainbow Dash have been a couple for years. But they've always been a little uncertain. Everypony who's tried it seems to think that you're missing out if your love life doesn't involve a cock. Dash gathers up the courage to ask Twilight if she can help. There has to be a spell that can turn a mare into a stallion temporarily, right?
It turns out there is. It only works for three days, though, and then it's a year before you can try again. So after weeks of psyching themselves up for this unforgettable experience, ready to spend three days in a room with no distractions but each other, Rainbow Dash takes the magical pill and turns into a stallion.
More specifically, she turns into Big Mac. This wasn't what they were expecting, but at this time of year three days of abstinence is almost unthinkable.
