"I don't know. Doubt you have what it takes to make me choke, English bitch." Barty rolled his eyes, clearly not too terribly insulted. He grabbed a thin chain from the top of the cage and connected either end of it to one of the nipple clamps. Then he finally showed the purpose of those rings bolted into the floor, as he connected the chain that was now clamped to Bill's nipples to one of the rings.

With his hands still cuffed behind him on the outside of the cage, that meant Bill had to lean forward. Either he had to stretch his arms or he pulled on his nipples.

Stress position. Well. Not quite yet.
