Lisa then noticed a uncomfortable look cross the other baby's face. Suddenly the invasive hand removed itself from her wet diaper as her mother held her stomach with a thoughtful expression.
"Mommy? What's wrong?" Lisa asked curious, momentarily forgetting that she shouldn't care if something bad was happening to her given she had just been assaulting her.
"I think I gotta make a poopoo" she replied unsurely. A sudden cramp in her belly that caused her to groan made her retract her previous statement, "Ooo...scratch that, I do need to make a poopoo."
Facing her daughter with a slightly strained look, her mother gave her a smile that was in no way forced as she was beyond excited for what she was about to do in a diaper. "Hold on sweetie...mommy's got to go potty...but it's okay because she's got her diaper on." she reassured before the pressure in her rear became too much.

Her smile widened as the back of her diaper then sagged downward under the weight she forced into it. She then finished pooping with a soft fart as the last of the tail of the brown snake left her body, now all being cleanly contained within her crinkly underwear. Reaching back there with her hand she fingered the monstrous bulge, overjoyed at its presence and the newly added heaviness of the warm lump of poop.
"I did it, I can't believe I actually did it. Did you see what mommy just did honey? Mommy went boom boom in her pants" she said, giggling at the terminology she used to describe her accident. It was actually her favorite word for number two, even more than poopoo which is why she incessantly teased her daughter with it whenever she changed her. But now such words would be directed at her. "I swear that was so much better than using the toilet."
Meanwhile Lisa stood by in silence at having witnessed her baby mother crap herself in front and then be happy about it. However the accident did give her a reprieve from the molesting so there was that to be thankful for.
