So I had this idea of getting estim pads (I'd found some that were like 1" x 2" and some that were just 2" circular. So the thought was to take 4 or maybe 6 of them glue them onto a 1" velcro strap (which I've used to cinch my gf's tits in the past). do this on both tits.

So essentially their would be 4 to 6 pads around each breast cinching them. Then having it randomly shock across the breast. (I'm guessing for the most part it wouldn't be a problem) If it went from one side to the other it wouldn't be strong, but two pads next to each other would be more of a shock.

But would this work and be safe? usually I've only seen a pad on each side. And I'm not sure about using more then one anyway at a time.. In any case I'll be doing more research..
