Don’t have tacksLay down on your tits, hands behind your back, your will use your legs to push you arround
Your task is to slide like that on a thumb tack spread floor.
As you have tied them to the point , where they become like this, assuming they are still tied up, use something spikey , like a hairbrush or brush to clean clothes to spank 200 times each, no matter how easy you go on your tits , as they are bound they will soon hurt like hell.Don’t have tacks
It may be the wrong choice of words from my side , but that piercing is more or less the intended result, but of course, it can be done without piercing if she uses a non sharp or bald thumb tack to just have pain.Tacks between clamps will more than likely just pierce the Nipple. It is not the same concept as a tack bra.
Ima be honest here, even a blunt tack would probably pierce skin.It may be the wrong choice of words from my side , but that piercing is more or less the intended result, but of course, it can be done without piercing if she uses a non sharp or bald thumb tack to just have pain.
I am gonna be direct with you, if you had said all this while i said to try it with a normal tack ( sharp or pointy pins), i would have accepted it as subzzzero said in the first response of my comment, but I do know that a simple clothes clip does not produce enough pressure that a bald tack can piercer the skin. ( saying after had seen someone do it)Ima be honest here, even a blunt tack would probably pierce skin.
And what then? Now she got a bloody pierced nippel with an unhygienic blunt tool.
Would you take covet of any doctor bills?
I highly recomend you ether try these things out on yourself first or leave them be altogether.
