And you know this how?
When I fucked her and her pal years ago in the Colinton Cathouse, she was the one who went off to act as a go-between with the head madam/pimp in regard to extras for anal, girl-girl etc - while she left me alone to play with her pal for a couple of minutes. She was also evidently the senior half of my own particular bedroom relationship, telling the other in Spanish how to lick her, holding her hair and giving her instructions throughout - despite the fact I never asked for any sort of domination or roleplay.
She was also talking to other girls I saw, but didn't fuck, with an air of middle-management authority, and was able to point out who was who - and who did what for how much - in anticipation of a future return (less pished) visit.
I think Matrix possibly has some more concrete experience of her actually being top dog in one of the many San Juan-burgh brothels he's frequented, as if Oliver Reed was a sailor, over many the years. So perhaps he can fill you in.
