Never seen her but Mistress Emma is always keen on it and well setup for it, mid 50's and will charge you $250 for everything for the hour, she's a Dom but will relax things for someone that wants to get soaked with her
I have seen Mistress Emma a number of times although never for W/S. Very good as a Domme so imagine her G/s would be good. An older BBW so not everyone's taste
Haylee (ex 1NS) offered watersports as an extra and, in my experience, appeared to enjoy it.
To note, “watersports” means you doing the pissing, not the escort doing the pissing - that’s a “golden shower”.
One thing to be aware of is how difficult it can be to get satisfying load of piss off with a semi, particularly post-cum. I recall having to run my cock and balls under the cold tap to settle things down enough to start flowing.
