How's the breathing? The mistress asks curiously, addressing the slave. He wrings out a short, It's going, mistress. Then he gasps for air again. The slave is standing under a crane. His hands are fixed to a metal beam. The cock is stuck in a penis cage.

It has exactly one opening. Barely bigger than a straw. Just enough air gets through that.
