What do you mean she was replaced half way through? You requested for a replacement or did the madam just pull the plug and called for a substitute?? Surprised you weren't asked to pay double..as you had tried both plates.
Thanks fella you i was thinking the same thing, i have never heard of this before.
The nearest was something that happened to me in a Romanian brothel when the girl couldnt get me to cum because they wouldnt do sex and the handjob was just shit plus i was annoyed by that poont, then they offered me another girl who would do sex so i said ok get her in here to finish me off to which they said you will have to pay her though wtf.
Needless to say i got dressed and left review to come soon
