Fluttershy and Twilight were in the library with me, and Twilight had just asked me if I could give her a massage.
...and other things.
I sighed.
"I'm sorry Twilight, but it would just be weird. You're cute, but I don't think I'd be able to get over the fact that you aren't a human."
"Well, what if I were a human?"
I chuckled. "Well, that would be nice, but unfortunately..."
Then I remembered I was dealing with Twilight Sparkle, one of the strongest magic-users in Equestria.
I asked her, "Are you saying you can you turn yourself into a human?"
Twilight's horn briefly flared a bright purple light. When the afterimages had died down, Twilight was gone and a naked purple teenage girl was standing in her place.
I stared at her.
"Twilight?" I asked hesitantly. "Is that you?"
The girl giggled. "Yup," she said.
"Fluttershy," I said, not breaking looking away from Twilight, "you might want to leave now. Things are about to get freaky up in this treehouse."
I walked up to Twilight, wrapped one arm around her waist and pulled her in towards me. With my other hand grasped her hair at the base of the neck and firmly but gently pulled downwards. Twilight moaned. I gently bit her neck, causing her to moan some more.
I heard Fluttershy mumble something, but I honestly couldn't tell you what she had said. There was a naked, attractive female who wanted me as badly as I wanted her, and I would have her.
So I did.
As I later found out, Fluttershy watched.
