Sarapeno on Reddit gives Dom/sub ideas on how your dom can make you feel owned.

"Wear something like nipple clamps or ankle cuffs under your clothing where no one can see…"

● WHY DO SLAVES WANT TO FEEL OWNED?

The main reason a sub/slave would want to feel owned is to be constantly reminded throughout the day, whether in subtle or strong ways, that they are under the Dom’s/Master’s control. When a slave is reminded of their submission and feels owned, the relationship becomes fulfilling for them.

● HOW CAN I MAKE MY DOM PARTNER FEEL LIKE THEY OWN ME?

The trick to this is to think of yourself as your Dom's 'property' and offer yourself to them. You should only do this to someone you trust, of course.

Making your slave feel owned is never a miss when it comes to Dom/sub ideas. However, the place of sanity, safety and consent can never be over-emphasized. Incorporate safe words and don't abuse your slave. Enjoy and stay safe!
