Hands free edging with steel rod and estim pulse makes crossdresser cum hard

In lingerie and stockings, my dick gets hard and twitches under the nightie as I switch on the electricity to my nipples and groin. Then I start stroking with a stainless steel rod. It slides in and out easily even though it's so tight. I turn up the pulse and bring out a bigger rod. I can feel the bumps gliding just skin deep beneath my fingers as my cock twitches along with the estim pulse. I bring myself to a very deep orgasm hands free.
