Read it online, or don't, it's up to you really: http://stories.kimintodarkness.com/fifty-tonnes-of-grey-part-1-the-first-month/

This is a bit of an odd story really, in that it contains the former fursonas/characters/whateveryacallsems of both myself and southchillreptile. Neither of them are in active use anymore, which might give some indication as to how long this thing spent in the planning stages.

It also takes the crown for possibly the most fetishistic thing I've written thus far, containing but not limited to: bondage, master/pet relationships, force feeding, weight gain, inflation, fart control and gassiness. And it's not even ten pages long.

Disclaimer: No, we're not actually in a relationship. Welcome to fiction.
Also disclaimer: Isn't really intended to be a parody of Fifty Shades of Grey, other than the name.
