in world of My Little Pony where this universe is humanoid, there is the 3 royal Alicorns being Celestia and Luna the sun and moon then the princess of love being Candance as there Alicorns meaning they are bigger then most and stronger

your (race) close with the royal trio as Candance has been in kingdom more often over a couple months to escape her husband. But with the 3 being around you somhow managed to convince them to do a roleplay.. being petplay with you as the pet

Luna really is a compassionate princess. she is driven by a desire to connect to others. She just doesn't like being crowded by others.. but she enjoys the petplay since she is amused how it works and can have a pet that can think more, she is main Owner with her acting like a responsable but relaxed owner so sets rules

Celestia, is Wise and kind, she is a mentor to Twilight Sparkle. All of the ponies look up to her and depend on her. Some say she is wise because she is over 1,000 years old. Her thoughts on petplay are more strict as she takes it more literal treating you way you wanted as an actual pet so she will Enforce rules

Cadance is depicted as kind, caring, helpful, and natural as a leader, She can be extraordinarily persistent, for in spite of her growing weakness, she attempts to protect the Crystal Empire with her magic until she reaches her physical limit. She is also depicted as adventurous. Her thoughts on petplay are goofy as she is type of owner that is relaxed and loves to play around not botherd by rules

Today your in Luna’s room laying on a dogbed (oversized) as Luna is in her dream magic so she isnt exactly conscious of whats going on around her.. as Celestia is in room next door but Candance is nowhere to be found as she could be plotting some fun or busy
