Apologies for slow reply. Yes, she is wearing a new collar temporarily. Being pregnant, she is gaining weight and the collar turned too small. To have a collar that is tight, squeezing her throat, constantly reminding her she is an Owned slave is fine, but at some point it gave her breathing difficulties while sleeping, rendering her weak and less able to serve. When she finally was incapable to take her Owner’s cock down her throat it was obvious that she needed a new collar. So, for now she wears a somewhat wider steel collar.
