So, I found a very effective way to let my new slave suffer when he misbehaves. While I'm not really into spanking him, instead I tie him up and apply a thick layer of Icy Hot to his balls and leave him to suffer in solitude. Effective, very!
Once his nipples have been tenderized - through nibbling, pinching, or clamps, rub Icy Hot (we call it Deep Heat here in the UK) onto them too.
Don't do it if there's any broken skin - unless you're a real sadist
In a Device Bondage (I think) movie I once saw PD dip cotton buds into mustard (or maybe wasabi) and slide them up the bound slave's nostrils. Eye-watering, to say the least! That guy's a genius.
I used to be an esthetician and there was this peppermint oil we used to use at the end of the treatment to awaken the client....it's milder than the icy hot, but works well when used with it.
My other idea is to get the icy packs for prolong punishment wear...but your ideas stanley will definitely be taken into consideration! Thanks!
