Can you recommend anyone in particular?
Not limited to Slough but preferably within a 20 min drive.
Depends what your budget is and whether or not you’ve looking for a professional level massage with HE or a more of a GFE.
Hot Kisses (Colnbrook) is fairly well reviewed, or if you’re looking for a larger, older unit then Paloma of Colnbrook has a few positives.
Just search here for Slough or Colnbrook or on AW using SL1/SL2 or SL3 for Colnbrook where there may be some more reliable choices. Then cross ref. Their AW Id here in the search box.
Edit: few up the road in Maidenhead too.
