Tangentially, That would be an amazing mindfuck, I've participated in a few things like that within My Dungeon with My Domme Sisters.

I've also had new Dommes pretend to be subs or send their boyfriends in for sessions to see what My place was like and try and get training in the most backhanded way. Funny to see those women advertising later on knowing they weren't trained at all.

Philly has had a long history of weirdness between ProDommes that I hope is in the past, so I don't doubt Mistress Tissa has experienced some sort of 'espionage'.

It can be difficult to navigate relationships with other ProDommes in the same city fighting for the same submissives. I believe respect for other Professionals, even through competition, is what keeps us safe--- but that's definitely not a mainstream point of view!
