Well, it can be ponies then. Why'd you suggest anthro then in the first place? And give me a sec to start it.

Well, really I would prefer either pony or humans... ^^;; Anthro... I don't know, hard to relate to for me.
Is it really important for you?

I guess, you can start just with a short description of Shining (maybe at his first wedding night? Or next morning?) and then Candance will arrive with her ideas. ~__^

That sounds like a good enough plot, I like it. And can it be anthro please? And do you want me to start or do you want too?

It's possivle, I think, though I wouldn't mind to be Shining Armor too. ^^
Ok, I guess it would be like that: after the wedding Shining Armor finds out that his wife has rather an odd interests, she misses times she was a nanny for little girls, and sees her husband as possibility to get back to it. Shining Armor doesn't like that idea and protests and such, but nor actively enough to overcome Candance's enthusiasm (you knoqw that plot "I don't like it, but I would only protest then you put me in diaper, not run away or fight").
I guess, later Twilight might visit them and take part in "little girly Shining's upbringing", must be really humilating to be seen by one's little sister like that. ~__^

Do you want it to be pony, antro or humanisation?

Yes, that idea is still open And I think I would rather be Shining if you don't mind.

Hello. Id your sissy Shining Armor idea still open?
And do you prefer to play him or Candance?

Well, I'm not sure really, Especially since we can't make decision about plot. ^^; Maybe we can RP some day later, then one of us think something up. )

Hmm... not sure yet. Maybe a toilet problem or maybe they decide to switch roles?

Well, that's better. )
For what reasone? I mean, what would be the plot?...

Oh okay. Well, how about son diapers father?
