Cock Trainer Lexi is the cock trainer. She is edge training her slave to control his orgasms and cum on her command. She mercilessly teases his cock to the brink, keeping him right on the edge. When the slave can not hold back any longer and begs to cum she delivers hard slaps to his balls with her crop, forcing him to withhold his orgasm. Slaves must learn to control their orgasms until the Mistress allows.
