I've never been really familiar with the term "service top" over the years, but decided to look it up a couple of days ago when it was mentioned in something I was reading. The definition(s) I read were fascinating and this one is the most recent of the ones I saw and is typical:
https://www.kinkly.com/definition/service-top/In my time in the scene I've done sessions, not lifestyle, but as a regular with a few Mistresses, they knew what I liked and what my limits were. And, more importantly, I knew what THEIR limits were. I'm all about role play and I usually outline the scene and the activities I like with someone new and let the Mistress take it from there. I'm certainly not someone who "tops from the bottom," who from what I have heard from dominas over the years and read, are one of those who wants specific dialog, costuming, etc., etc. For me it's ad lib, and the fun is seeing where are certain scene goes and how it ends up, because that's how I learned about and began to crave certain activities I never experienced before.
Looking back on my sessions over the years I've seen some "service tops" over the years. Mostly they were "escorts with a whip," who indicated they were into kink, were good at it, but also offered vanilla services during play if requested. The real professional Mistresses never (or hardly ever) did anything in my experience that was illegal.
Am I misinterpreting the definition? Any views on this subject?
