I chained her, standing to the wall, and used EMS pads on her to make her shiver and quake uncontrollably. Watching her boobs sway from the spasms was an amazing visual. What made it even more special was that Katie does not do girl/girl very often, and only with the girls she really wants to play with. I introduce her to the zapper and let it do its magic all over her body, especially on her nipples and clit.
She proved herself to be a good little sub for her first time out and I rewarded her with a squirting orgasm, which she splashed all over my hand. I smeared her girl-juice all over her face as her hard-won reward..
