The first week, she can touch however she wants and cum as many times as she wants. She cums every day, sometimes twice a day.
The second week, she can still touch as much as she wants, but only through panties. And no cheating and pulling them to the side, either--the only contact that's allowed is through a layer of fabric. She cums nearly every day, her panties a sticky mess.
The third week, she can only touch through two layers of fabric. Panties and pants or a skirt. She cums once, leaving herself with messy clothes and no satisfaction the rest of the days.
The fourth week, she needs to add a blanket, too, before she can touch. She doesn't cum at all.
The fifth week, two blankets. She has to stop herself from rubbing herself on things as she walks past them, just to get some stimulation. She doesn't cum.
The sixth week, she loses the use of her hands to touch. Instead, she can only hump a pillow, and only through two blankets and two layers of clothing. She's rarely not wet. She doesn't cum.
The seventh week, the pillow and blanket go away, but she can only hump the air, still fully clothed. She's desperate enough to try for hours. She doesn't cum.
The eighth week, the humping stops, too. She can try to clench her legs together, but only when wearing panties and pants. She tries anyway. She doesn't cum.
The ninth week, her clothes are taken away, but she's strapped to a spreader bar and allowed no stimulation at all. She leaks constantly. She doesn't cum.
The tenth week, a vibrator is pressed against her clit and turned on to the highest level.
