In a dimly lit room, a crossdresser stands, clad only in a pair of panties he's been forced to choose. His femdom, seated comfortably, watches him squirm. "Pick wisely," she purrs, "each pair has a story, a purpose." He scans the rows, his heart pounding. He selects a pair, his hands shaking as he hands them to her. She smiles, a hint of cruelty, "Excellent choice. Now, put them on and let's begin your feminization training." He complies, the panties' silky touch sending shivers down his spine, marking the start of his sissy transformation.
