On one chance day Sweetie had met upon a creature she found quite strange. After some investigation, a small chat, a missed boop and a taste later Sweetie had found Equestria’s hot new trend.  
The delicious creatures from somewhere beyond were not only of great taste, but offered quite a tension relieving massage from within and a very satisfying experience all the way through. Leaving any pony lucky enough to encounter one quite pleased.
 
(Request by Bliss as a precursor to Sweetie’s human disposal. Made quite a few mistakes with anatomy on prey, but only noticed quite a bit after. Special thanks to Marader4 for the idea of human prey being a hot trend.)
