A good girl doesn't touch herself like that.

"I've noticed you've been having some trouble controlling yourself at night, William," his mother said calmly, her eyes never leaving the small cock before her. "A good girl doesn't touch herself like that." She paused for a moment, letting her words sink in. "From now on, wearing a diaper will be part of your daily routine."

William felt his heart drop into his stomach as he realized what she was suggesting. He had never worn a diaper before; it was something reserved for babies and toddlers - not eighteen-year-old boys (or girls). But before he could protest further, she continued speaking in her stern yet seductive voice.

"You'll have to learn how to be obedient if you want me to take care of you from now on," she said matter-of-factly. "And part of that means allowing someone else to handle your personal needs." The way she said 'handle' sent shivers down his spine as he felt himself growing even harder beneath her gaze.

"But Mommy..." he stammered out, his voice barely above a whisper now. "I don't understand..."

"You don't have to understand, William," she cut him off sharply. "All you need to do is trust me and obey my commands." She leaned in closer, her breath hot against his neck as she whispered softly into his ear. "Remember, this isn't about you being a boy or a girl anymore... It's about becoming the woman I know you can be."

With that final words, William felt himself lose all sense of control as he surrendered entirely to his mother's will – both physically and emotionally.
