A most interesting start. You definitely set up a scene that is believable and not at all forced. It genuinely gets your curiousity, as it did with Big mac, while leaving a nice tease to figure out exactly what Rarity has in mind for his intrusions along with just what the purpose in having such items in her stock is all about.

Rarity Femdom with Big Mac ABDL/humiliation/sub, I can't wait to how this is going to go forward from their, I hope this is going to be a long and exploratory relations they would develop with each other. I wonder if it will be manipulation and blackmail will Mac will get into it of that he will just be discovering a new side of him sense Sisterhooves Social . Can'T wait to see the next chapter.

This story is off to a great start! This story is very appealing and you've hardly begun.
I wonder if the red from a spanking would show up on Big Mac's backside?
It seems we'll most likely find out, along with other plans within Rarity's devious mind.

But scriiiiiibe, we need moooooore

Can't wait for more of this!

A great start to what I see as a great story, there aren’t enough padded fics of Big Mac.

MOAR!!!!!!
