I agree the idea of being exposed and tied to something relentless like that is an enormous turn on. I don't know if it would be reward or punishment though if the speed/force was turned up enough and I was left to it's mercies long enough. It might be fun to find out how long it would take me to beg for it to stop.

*grins* So if anyone does find an inexpensive fucking machine. Please tell me!!
