I've been experimenting with self bondage as I don't have a partner at the moment. My major problem to date is that after any period of time if I don't have a way of simulating my self I could get bored. As I want to try bondage positions that would prevent my hands from providing said simulation I am in the need of some device that would so such. I've tried a few items but haven't had any luck yet. Anyone have any suggestions?
