Vincent had never been a crossdresser.

He sat rigidly in the padded chair, the metal frame of the observation booth cool against his bare shoulders. The room smelled of antiseptic and something faintly floral-perhaps the residual scent of the powder they had dusted over his skin. Outside the glass walls, technicians moved with quiet efficiency, their faces blurred by the one-way mirrors. Inside, the only sounds were the soft click of buckles and the faint hum of monitoring equipment.

They had strapped him in carefully. Wide white canvas bands crossed his chest just above the cups of the bra, pinning his arms lightly against his sides. Another belt cinched around his waist, securing the high-waisted girdle. Soft cuffs held his wrists to the armrests. He could still move his hands a little, enough to feel the smooth, unfamiliar fabric against his palms. The stockings-sheer brown nylon-whispered when he shifted his knees. The garters dug gently into his thighs.

Vincent stared straight ahead, jaw set. The pearl necklace rested against his collarbone. Matching earrings brushed his neck whenever he swallowed. He had refused them at first. They had simply waited until the drugs made refusal feel distant and unimportant.

The experiment was nearly complete.

In the beginning it had been clinical: questionnaires, baseline measurements, carefully controlled exposures. Then came the conditioning sessions-images, sensations, rewards and aversions delivered with precise timing. They never explained the full protocol. They only said the goal was to study the plasticity of gender embodiment under forced association. Vincent had signed the consent forms because the stipend would cover six months of mortgage payments and because his wife, Elena, had signed hers first.

In another room, identical in every detail, Elena was undergoing the inverse protocol.
