Donna is cuffed to the ceiling after Step-Daddy has given her several fast acting laxatives. She struggles to keep her diaper clean, but it's a lost cause. She thinks she is only passing gas, but after a long fart she can feel the diaper filling up as she involuntarily empties her bowels. By the time she is finished, there is a massive bulge in the seat of her diaper and Step-Daddy is quick to point it out.
