*You're at a library, when you see a woman screaming at an employee. That poor employee, you thought, then cursed the girl to become 16 years old and ditzy, as she wobbles around, unable to focus on anything. She flops onto the floor, unable to get up. She screams for help, but you shove a foam ball in her mouth, and tying masks above and over her mouth and nose, making her face a full red from sweat. You tie her body in the strongest knot you know, making it impossible to untie it. Her breasts grow a few cupsizes and her shirt now reads; "Gag slave.""

Mmph, Mmmm~ she can only make noises due to the foam ball permanently in her mouth
