If I crawl fast with good form I get the hitachi, if I don't - first I get my anal hook pulled on, and then for safety reasons, the clip is clamped to my nipple to shut off the treadmill
Being trained to walk the treadmill in 10 inch heels with a buttplug tail, nipple clamps and hands tied behind my back. The safety clamp connected to my clit so that if I slow down it gets pulled!
