Bound in her BDSM dungeon, a sissy man awaits his mistress's command. She enters, clad in leather, and orders him to choose a pair of panties to wear. His eyes dart nervously over the array of lace, silk, and satin. She smirks, enjoying his discomfort. Finally, he selects a pair, and she helps him slip them on, running her nails along his thighs. She admires her handiwork, then takes out her whip, ready to continue his bisexual feminization training.
