i have also been using this one at night trying to get it to work while i sleep although i dont seem to actually be going into trance i have noticed a diminished amount of time i get a rise out of my Mistress's dildo. With some work i can still get off though most of the time a must use other means in conjuction with standard masterbation. i wonder if a deepening file would help get this file to work better,as i would eventually like to get the superfemalewhammy file to work as well
