Milked by Mona and Lexi

Mistresses Lexi and mona have promised their slave a reward for taking pain - a milking by both of the Mistresses. Of course, there is a twist - they insert a sound into his dick while they are milking it. In no time, the combined pleasure of the sound fucking and handjob has the slave begging to cum - but when he does, the weight of the sound blocks the cum from being released. The slave moans in agony from the pressure of the blocked cum while the Mistresses laugh at his frustration, making fun of how pathetic he "came." The Mistresses continue milking him with the sound until he begs to cum again; this time, he actually produces enough cum to cause the sound to rise, releasing some cum from his penis - but leaving him with another totally ruined orgasm. The Mistresses then spit on his cum covered cock and balls, leaving him bound and still sexually frustrated. After all, orgasms are only for a Mistress's pleasure - not a slave's.
