i have to admit that part of me has always been interested in exploring something along these lines just to try something different. the mistress ayumi website looks interesting and from what you can see of her, she looks pretty hot. but i noticed it said "DO NOT ask for any sexual services, intimate body worship nor scat"
for this to not involve any sexual services would be kind of a deal killer for me. i wouldn't mind exploring some of the different fetishes, even the torturing/humiliation type ones as a kind of extreme extended foreplay that would eventually make the end orgasm more intense and pleasurable. but to go through all of those fetishes and NOT have any sexual service or finish would just not be worthwhile particularly if it really costs $3K + $500. For that price I'd rather have 4-5 TST HG's!
