A cruel mistress takes a new slave through a rigorous training session, focusing on his minuscule endowment. She parades him around, exposing his tiny cock to the world, delighting in his embarrassment. She uses her powerful body to grind against his pathetic erection, laughing at his futile attempts to satisfy her. The session culminates in a degrading act, highlighting the slave's small penis and leaving him in a state of utter humiliation, his tiny dick a constant reminder of his place at the mistress's feet.
