Only girl I’ve ever seen who regularly gives more time than advertised - would love to get inside them shorts... 
That's why I generally don't go for these types of bookings, the
frustrationWhen you're used to getting your cock sucked then getting the pussy & maybe the arse as well, just a wank is like just having the starter when you're used to a 3 course slap up meal

Think a pop at the start then a relaxing massage then another pop at the end would be decent tho.
Something I'd like to try anyway.
