A Fluttermac story

Fluttershy and Big Mac were kissing under a willow tree. Fluttershy saw Big Mac's cock for the first time. It was a little smaller than his leg, and two inches littler than the length of his leg. She didn't know how it even fit. When they first had sex (which was six days before she was pregnant) he was up to his penis.

     "Actually can you not" Fluttershy.

    "Eeyup" he said.
