Why not both?

You go outside,coffee in hand,and freeze time. Setting the drink down,you walk over to the two ladies. Starting with the auburn-haired one,you take her shirt off,revealing she wore no bra and had a decent pair of tits to work with. Next was the one with black hair. You pull off her top and blue bra to see a small pair of tits,but you weren't complaining.

When time restarts,you will not notice you are missing your tops.

You unfeeze time and the two continue to chat,not noticing anything wrong.

Say your names out loud.you command.

"Sarah,"says the one with auburn hair.

"Mindy,"says the one with black hair.

Concentrating on Mindy,you give the following command:

Mindy,you are now Sarah's pet. Just an animal. A sexual plaything who follows all commands from her mistress. Following Sarah's commands make you horny. Being degraded makes you horny.

Next was Sarah's command:

Sarah,you are now Mindy's owner. You do not view her as an equal,but as a pet. You will do everything you can to humiliate her. You are also a nudist.

With their new commands implanted,you wait to see what will transpire between the two.
