Twilight's Big Mistake Finale Question (Patreon)

Given the megadicks I've been writing recently, my thoughts returned to that 'extra' ending of Twilight's Big Mistake that I had in mind. Ultra-macro is a given. Twilight's cock will grow and Pinkie and Rarity will continue to get taller and curvier as they fuck Twilight and absorb her cum.

But there's a few options floating around in my head and I wanted to check with you.

Should Pinkie and Rarity grow cocks themselves? If they do, the obvious narrative for me is that they use those to enhance themselves even more and end up humiliating Twilight with their superior cock size. Or maybe there's a sweeter ending where Twilight learns to give in?

Should any more ponies appear? I don't want things to feel too rushed, but I wouldn't try to extend this part too long either. My original plan was to throw in Rainbow Dash as well to kick off the real crazy part, but potentially I could add a whole lot more, just to heap on the macros and smother Twilight under a multitude of curves (or, as above, cocks). In this case, multicock for Twilight is a given.

Clones are still an option, but kind of left field at this point, so I'm more inclined towards the above.

It'd be helpful for me if you could indicate your interest below, or add comments. You can select MULTIPLE OPTIONS.
