Tail is an anal plug, so anal play comes first. Tail also tells others WHAT kind of pet, pet is. I myself am a Kitty.
Gag is as pet is being trained as a pet and to prevent them from speaking, some owners will even get a themed gag like a bone or a fish for their pet.
The limbs are sometimes bound to where pet is walking on knees and elbows only.
Pet is also not allowed to go potty unless owner says so, and usually only in back yard.
Species of pet wether a kitty or a puppy is something that both agree on irl
