This fetish is almost perfect for Flutterspike. The only creature Fluttershy is afraid of is dragons, however, she isn't afraid of Spike.

But, Spike will get older, and she'll become wary around him.

She wouldn't want to be around the big, scary dragon; all the things he can do to her will ravage her poor mind!

Then, she start thinking of all the things he can do to her.

Hell, you can do it in reverse: have Spike be the prey and Flutterbat the predator!

Hmm....

This does sound like an itneresting concept.

2772475 Yet another good idea JD. Though it's going to be one I won't be able to do for a good while since I have my hands full.
