A steamy bouncy-bouncy dat's shared while said passionate lovers are hunkering down inside da circular coil-core of a giant power-transformer.
Having a torroid affair can indeed be exciting and satisfying, but you will want to make sure dat nobody accidentally turns on da "juice" to said massive power-unit while you two are in da middle of "swapping your juices" inside, so dat said tinglingly-invigorating encounter doesn't become an "electrifying" experience!
