Torment Lavender

"Vestimenta captionema," said Ginny as she zapped Lavender. This particular spell would make it impossible for Lavender to change her own clothes. No matter how hard she tried, she would not be albe to get that diaper off or even pulled down.

Lavender walked on.

"Visceribus vacuumia," said Ginny as she zapped Lavender again.

Lavender stopped and put her hands over her stomach. "Oh no!" she said as she felt a gurgling and intense pressure in her bowels.

Ginny smiled. This was really turning her on watching Lavender about to fill her diapers.
