Wow, that sounds really intense, i bet its alot of fun.wax play is definitely something id love to try.
Was flicking through the bondage section yesterday and noticed a few of the nipple to clit/labia chains have O rings in them, instantly started thinking how clipping some cuffs to that would work well for solo.
nipple clamps to cock ring chains too. Lots of collars with nipple chains and normal nipple chains though that could also work with a long connector chain
(Edit -found one, my mistake
