Under the watchful eye of their dominant mistress, a submissive begins their sissy transformation. The mistress, a seasoned Femdom, teaches the sub the art of pleasuring themselves with a strap-on, guiding their hands as they learn to thrust and grind. The sub's bisexual nature is explored as they orally service a hard cock, the mistress coaching them through every slurp and gag. Finally, the mistress anally penetrates the sub with a strap-on, training their ass for the real thing, all while the sub's face is contorted in a mix of pleasure and pain.
