Happened me a few weeks ago, the following is completely true bill.
Booked a massage and pampering session in a South Dublin Salon a few weeks back, and upon entering I was directed to the room where my session would take place.
Instructed to strip, and got into a bath that was drawn for me. I did think to myself this woman (Eastern European with legs up to her armpits) is familiar looking.... But couldn't place her.
Bath over, brought to room, told to lie down on the massage bed, face down where I got the usual rub, top to bottom etc. Told to turn around where this masseuse had now stripped to a thong, and nothing else, and decided to go to town on my pump and tool bag, I had a nice feel of her all over. Climaxed, said my goodbyes and left, all the while still thinking I know her from somewhere.
Turns out, she's only a neighbour of mine, a few mins walk away, who I see regularly out exercising, and have always thought "wonder what she does for a living".... Didn't recognise her immediately because her hair is tied back and under a hat when she's exercising, whereas at her job it's down and gives her a completely different look.
I don't think she recognised me, not that bothered either way, as I never asked about a HE it was performed on me without me even asking.
Before anyone asks why I didn't walk out, well firstly that would have been worse in my opinion, and secondly, penny dropped the next evening when I seen her walking again as I drove past.
I've had similar fantasies before, and am still trying to come to terms with the reality of my neighbour massaged and brought me to climax.
