Ideas for Sexting?

Me and my Girl are into BDSM. Since we can't meet often, we sometimes like to sext for a few minutes/hours. We are into Dom/sub Things and love to play with things like humiliation and commands. I (M) am usually the dominant part but we startet to switch often. we kinda got out of new ideas. So if you have similar interests and have some kinky ideas... Please tell me
