Mistress BlackDiamoond and her friend wanted to reward and punish their slaves at the same time. They undressed their slaves before they jerked them off. However, the mistresses made sure that each slave would cum into the mouth of the other slave and that way, they would lick and swallow each other's cum. They had fun when they were being jerked off by the soft hands of the mistresses but they had to endure swallowing each other's cum.
