I also like the objectification FTT videos. Some of my favorites are (I'm linking to their paid stores as to not take part in the unauthorized distributions that we all know are out there):

Love this description:

"Breakfast is the most important meal of the day, even for a pig, TOILET PIG. So even though I have to go to the gym I graciously take the time to feed my perverted toilet pig.
I know it seems cruel, but if all you will ever be in life is a TOILET then showing you sympathy and encouraging false hopes of ever being considered human by me is by far more cruel than simply using you like the toilet you are. So, fashionable as I am, I do not always get dressed up when I use my toilet. I don't get dressed up for a pig."

Zephy has a fitness model's physique, and she seems to enjoy using her slave as a toilet

Who did I miss?
