Weird thing that happened to me years ago. I'd sessioned with a professional domme, and after the session and orgasm, she gave me permission to shower... but forgot to give me permission to get dressed (just turned out to be an oversight on her part). So after the shower I come back naked into the room, and ask her permission to get dressed. She looks at me and clearly thinks about it, but instead of giving me permission to get dressed, she had me help straighten up for the next 10 minutes. I hated every fucking second of it, I hated obeying her, I hated cleaning, I hated being naked (I was actually a little self-conscious and embarrassed about being naked, rather than turned-on as I am during session). Then over the next week, I found I kept fantasizing about it -- it was like this "pure" post-orgasm humiliation that wasn't driven by sexual-submission, and I loved thinking about it.
That was a real discovery for me. Ever since then, with both pro dommes and especially in my personal life, we often engage in "post orgasm protocol". In a way, it remains a love/hate thing for me -- hate having to do these things post-orgasm, but also ... love the purity of it, love what it means as a gesture to my beloved mistress. Often we have set protocols; my current mistress might dictate something like: come out of the shower naked, submit to some more CBT just so I'm reminded who's boss, fetch her a glass of wine, rub her feet while she watches TV. Sometimes post-orgasm protocol is focused more on humiliation, sometimes more on service; there's times she keeps me in genital bondage or nipples clamps, sometimes she keeps me naked for hours. A weird thing has happened along the way, I've kind of become conditioned to view this as the way things are. I still don't feel very submissive post-orgasm, but in a weird way I savor the "pure" service/humiliation/obedience that comes afterwards anyway. And again, I love the fact that I'm doing it for her, even though I don't feel submissive at all anymore.
So, long story short: perhaps talk to her about making up some post-orgasm protocol, so you know your orders in advance, and have to stick with it. "You'll be naked for 2 hours after you orgasm; during that time you are only allowed to crawl to where you need to go, except when you are serving me in some way; if I detect any hesitation at any time I will say 'present yourself' and you are to bring me the crop for 10 smacks on your cock" etc. etc. It really worked for me as a pre-planned extension. My mistress and are I 24/7, not just scene-based or session-based, and it keeps her happier this way, too
