Best of seeing a WG on AW etc than a massage lass if youre after a blowie only
It'll be cheaper and you'll get what you want.
£40 massage + £30,40,50,60 (?) for a blowie. £50/60 for OWO and sex from a WG, may be only 30 min, but you get what u want
Wouldnt bother trying you luck with a blowie at a known legit place, wasting your own time and money
