There is one guy i see at the parlour who always over runs by at least five minutes, and i swear he is edging for the last half of the booking, he never books longer and i'll be telling him he has ten minutes left and he continues to edge untill the time is almost up then he builds up to an orgasm.  I can understand guys wanting their moneys worth or just to prolong their pleasure or having trouble cumming but he just takes the mick every time.
