I can't give you any recommendations because blow & go isn't a service I am into. (A GFE with some time to relax and shower. is more my cup of tea.)
Having had a look at your posts, I'm guessing you've been finding masseuses through vivastreet or one of the many other was that massage parlours advertise. A better way to find the kind of services you are now looking for is AdultWork. A search on AW reveals 39 WGs who can accommodate, work in Reading, offer CIM and quote a price for a 15 minute service (although some of these are based in nearby towns and probably don't "accommodate", i.e. do incalls, in Reading). I suggest you pick a WG who looks right for you on age, looks, location and price and then search for reviews here on UKP. A good way to search here is using the number in the links like
External Link/Members Only that you'll find towards the bottom of the AW profile pages. N.b., that's an example, not a recommendation - I have not seen that WG myself.
Cheers!
