During the past one year I have done a lot of tickling sessions with an escort woman, with who have developed a special chemistry and keep communicating even when she is not in my city. She is definetely submissive, but has never done tickling sessions professionally or in her private life besides when I tie and tickle her during a regular sex appointment through her agency. Trust me when I say that she has the most ticklish feet on the planet.. even holding her foot tickles her and when I lightly tickle with feather or nails she is an instant screamer. I usually kiss her toes or even worse for her put them in my mouth with the high risk of being kicked and tickle her soles at the same times which she can handle for like 10 seconds before screeming and thrashing so hard that I need to hold back. But when I use the brush or electric toothbrush it is something I can't describe.. she has broked many times my handcuffs, leather straps etc and most of the times I give her a break as she becomes red and sweating in seconds and also because I am afraid that the neighbours will call the police or something.. so lately I use rope bondage and all my bodyweight pinning her legs down to keep her immobile while torturing her soles. As much as I have tormented her she always tells me she loves it and never complained or asked me to stop, only asks for breaks. She is an amazing person and a fantastic ticklee but sometimes I feel that if she were a little less ticklish we would enjoy it more!!
