The slave is suffering, the Mistresses are getting more excited. After a while though Mistress Ava calms down. Maybe it's the calming effect of impaling someone's nads on her shoes? Maybe it's the funny sight of the slave catching an inappropriate hard on while she is aiming at his balls. Whatever it is, the Mistresses soon make up and tag team on the slave's cock and balls.

What a good bonding experience...
