Now this is something you don't witness every day, a custom metal suspension piece. This is what happens when ART hits BDSM in the face with a creative stick.

The huge hooters exposed, puffies popping out and straining, clamped and weighted. Her soles are revealed to caning and snapping. This is agony in its most charming form. No expect for pleasure, just a slow suffering...
