Nikki is diapered and reading a magazine on the couch when the urge hits. She knows the toilet is off limits, so she finds a comfortable position on her knees and gives a good push. As she empties her bowels, a large bulge appears in the seat of her diaper. As good as it felt to get it out though, now she doesn't want to sit in her own mess and just stays on her knees as she waits for Step-Daddy to change her.
