Similar thing happened to me today. Went to legit place. They tell you to keep underwear on then tuck towel into undies and reveal your ass. Massage back with good proper massage, maybe a little bit more rubbing oil into ass than necessary but not enough to be sure it was deliberate.
Next comes the leg massage. Oil cleaned off back and ass, underwear pulled back up. Then undies pulled up from bottom to reveal ass cheeks again. Massage works way up leg then right underneath the underwear, around cheek and down almost to groin. This continues for a while, while i get very hard. A few times almost goes deep enough to touch asshole. Then she leans over so her pussy is touching my toes. I feel the pressure of your leaning on me so I wiggle my toes. She doesn't move so I start to rub my big toe side to side for like 5 seconds. Then she moves away, changes to other leg and doesn't go quiet as deep on the massage to the groin or down the ass crack.
I have no idea what to make of it - she obviously let me rub her pussy with my toes then changed her mind.
I have seen her before and felt her rub against my elbow or hand when massaging me but I never had the balls to rub her back until today.

Let's see what next massage brings. I am sure it will never go all the way cause there are no tissues around and only curtains between massage tables. But I am sure we are both enjoying the flirt. Hopefully I get a better rub, maybe with my hand next time...
