I can recommend Kat and Kate of those still around, both are genuine. Kat is total PSE, a real expert. Kate is total sex, totally involved. She had to be an escort. There is no way any one guy could satisfy her. The opposite to some of the very uninvolved Czech babes I have come across.
The best escorts are going to be busy and will not answer the phone when with a client so you have to keep trying and hope to get lucky.
