Goddess Tangent likes to do Team Building exercises with Her slaves, in order to improve their performance. In this case, they endure punishment together to build esprit de corps, in service to their Goddess.

In part2, the next team building lesson has both slaves nipples clamped and chained to each other while one suffers more CBT while the other gets paddled and spanked. If either reacts and moves too much, those nipples will pay the price.
