A curious crossdresser experiments with electro-stimulation and urethral sounding, alone in his room. He slips on a pair of silky panties, hiding his throbbing cock and balls, and applies the e-stim device, gasping as electric currents pulse through him. He pushes the sound further into his urethra, moaning at the intense sensations. His body convulses, and he cums twice, filling his panties with warm, sticky cum, before jerking off the remaining semen onto his toned stomach.
