I'd say both that be awesome.like Pinkies doing it for fun so she talks Futtershy to do it with her so you could be better friends.

I'm partial to agree

i think this would be a good time to add non main 6 after chapter this as in Big Mac and the CMC (Age up or legal age there) i feel this could be a good starting point for them... like Big mac walks in on them right after this act/ or smell u as ur leaving and gets him worked up ... or the CMC when ur walking home from the barn as ur cross there club house sweetie belle could be showing the spell she "borrow" from her sister book (the futa spell) and used it on the other CMC and need help revealing them self's

and what sizes u think they should be

7117730 yes, I thought about that too. But I'm afraid I have to stick to my voting system. There are only two more ponies left in the mane 6, so you'll see other ponies soon!

Futashy!!! Duh!

Fluttershy. And handjob. Ballgag.

Fluttershy should be last because she's the biggest.

I'm going to have to vote for Pinkie. I really want to see Fluttershy but I agree. Save the biggest for last.

I will also vote for pinkie to save the biggest for last.
