Mommy's new plaything, a sissy-boy in training, dons lady's lingerie and panties for the first time, blushing at the sight of his feminized reflection. His mommy domme, a stern and dominant woman, verbally humiliates him, calling him her 'sissy slut' and 'pussy boy'. She commands him to parade around in his new attire, rubbing his crotch to emphasize his growing bulge. As he obeys, he's filled with shame and arousal, his transformation into a sissy slut just beginning.
