This is a sexist joke that objectifies a woman and reduces her to a sex object that only exists to service and pleasure men and their erections. Just casual misogyny that subtly rewires men and women into treating women like pieces of meat.
The Milking Farm. A business built on selling breast milk and involves lots of humiliating and uncomfortable sodomy. My wife is recently widowed Carey Mulligan and by law everything she owns is my property. She thought she would escape the indignity of anal sex but she was wrong.
Cows for milking. Large breasted whores that are kept as breeding slaves in cages on all fours. Their swollen tits constantly milked as they penetrated and impregnated often. Once pregnant they can be punished with anal sex because why not.
Pony girls that are more for decoration but required to receive anal sex whilst standing and cleaning each other's punished buttholes with their tongues of any sperm.
