Derpy loves muffins!
...a little too much.
...in a ponysexual way.
...in the flank.
...all night long.
..and the poor muffin was never the same again.
Seriously, though, folks, she's just... um... scratching her belly on the muffin. Really.
No I'm not.
I kinda doubt this needs a mature content thing set? I mean, really.
