Massage parlour in the centre of Highbridge. No website so far as I'm aware. Phone no I have for them is 01278 781177. Easy to drive past on a first visit, but once you know where it is it's no problem. Municipal car park is on the opposite side of the road, or you may park a little further away in a residential street and walk.
I believe Cleo's is open from around 10:30 am until the early evening, Monday and Tuesday, Thursday and Friday. My experience is you just rock up and see who's available, and will be invited to wait in a lounge area if the girls are all busy, or the one you want to see is busy, and offered a cup of tea. There may be other punters with you sat in the lounge.
On my last visit three WGs lined up for me to choose from, and my choice led me to a downstairs room after I paid £10 to the hostess. This room is separated from the lounge by a lobby so very quiet and private. Shower in the room, and a double bed (on previous visits there has been a massage table) £40 in the room for brief massage as a prelude to OW, RO and covered penetration. So far as I know OWO and CIM are not available. Sometimes there has been FK, sometimes not.
In summary, easily accessible from a couple of M5 junctions, which lead onto the A38 which passes through the town. I've always found Cleo's to be good value, clean and friendly, and good service - albeit standard massage parlour fare, with no OWO IME.
