Never done a domination session... Interested but have Q's

I'm interested in booking an appointment but I'm not sure what exactly id be getting.
The list of favourites is obviously different from a regular escort.
Is sex with the dominatrix not a done thing?... Is the entire appointment just about the acts of Dom/sub without any release at the end?

Thanks for any info.

Depends on the lady in question. Some do, some don't. But "release at the end" is something that I would assume happens

It's what keeps u cumming back
