Black Label - The Humbler Steel BDSM Humility Device

Stretch your balls with an edge. 

This one - when applied the right way - hold your balls back when the long bars on the side uses the back of your legs to even stretch your balls harder. How hard is for you to decide. 

Did you ever perform a squad? Look into it and try it out, but watch out you don’t stretch to far, you might tear you balls off.
