I once did a straight fw 3 hour punt in the morning with a sub, 9:30AM!!! Then booked a mistress in the afternoon the whole thing was just OK.
On another time I booked a tantric massage in the morning which did not have a HE, but it was still very good, again mistress in the afternoon, this was a very good experience.
I once booked a overnighter and then we thought it would be fun to book another overnighter from an agency and tell her that the first lady was my wife and the new lady was my birthday present. I kept nipping out for a smoke with lady two and she kept on going, fuck me your wife is top booking an escort for you, this is amazing but not really the same as two in a day as these over lapped, the start was staggered though.
