I saw a provider named Mistress Magika a few times, she worked with Mistress Lotus. She used an electrical stimulation  device that I think was called a TENS unit.
Unfortunately Mistress Magika is no longer around.  I would love to experience one of those TENS units again and am wondering if anyone local might use one of those in their appointments. Also if Mistress Magika is still around I’d love to see her again.
