Rapture's slave made the mistake of saying he can breathe sometimes when she's sitting on his face. Rapture finds that unacceptable, and ties him down to the bed so she can fix the problem. Rapture proceeds to smother her slave way past his comfort level. She sits all 190 pounds of her Muscle Goddess body as heavy as she can on his face. It seems the more he struggles for air, the longer Rapture sits. Even as his feet begin to kick and spasm from lack of air, Rapture doesn't let up. That should teach him a lesson.
