Skyler squirmed at her desk.
"Thank goodness I sit in the back row" the petite brunette with the hourglass figure thought as she rubbed her plump belly through the soft fabric of her blouse.
It had started during her senior health class; one class after lunch. She had seemingly just sat back and begun to daydream when she felt her tummy rumble a bit. Naturally she felt full; she hadn't enjoyed the sandwich she munched away at while gossiping with her friends. But she knew she wouldn't feel herself for the rest of the day without a little lunch on her stomach. "So much for that..." she thought to herself as she felt the satisfying fullness in her stomach settle and become a lump in her gut and a familiar pressure in her bottom.
It had been nothing too serious during health class, but as she passed the girls room on the way to her last class of the day she hesitated, rubbed her belly discretely and frowned.
"I do have to poop... Quite badly now. But... It's certainly no emergency. Well not enough of an emergency to try to take a dump in the school bathroom."
She clenches her buttcheeks, not just at the thought of her round, clean white bum touching the gross toilet seat, but to hold in the solid load stuffing her colon to her butthole.
She took long strides to class; as if It would make the hour until she could relieve herself go faster.
As she slid her wide bum into the desk she settles into an agreeable position.
"Alright this should do the trick" she thinks as she tries to put her mind to something. "Sitting down is better. The chair will keep my poop in" She thinks happily. She adjusts the glasses that had fallen to the bridge of her nose, and pushes back her wavy brown hair so she can focus on something other than her urge.
