Bruce, if I were you, I would dive into this torture, learn about this Yoga. *evil grin* Why?
That is simple, TZ likes yoga and humiliating her Master, yes?
Well, learn some of those pretzle postions and then tie her into them since she loves them so much. Then, well, then, just leave her in them for a while ignored and untouched by her Master. True torment for a subby.
Just a suggestion, anyway, and a wonderful bit of Domly revenge. Just turn your fabled Blue BDSM barn into her yoga and bondage room, without the comfort of mats and the added help of coarse bindings.
