How many times do you expect to bang her, two maybe three? Why dont you just book separate outcalls, much cheaper AND you dont have to buy her dinner either.
Fair enough if it works for you, i just cant think of anything worse than prolonged small talking with a prossie in between fucks. She doesnt want to be there, and whilst boring her with a load of unintersting shit all shes doing is sitting there thinking what odious toads us men are
Have fun anyway
