He grabs her and pulls off her panties as she struggles. She's going to wear the diaper whether she likes it or not!Ally gets very mad as he puts the diaper on her, and tries to undo the tapes as he fixes the diaper on nice and tight. He turns Ally over and grabs some ties, then ties poor diapered Ally to the bed! She struggles but he's not having it. He leaves her to think about what she's done."You have to untie me. I have to go to the toilet!""The toilet is here! That's why you have a diaper on, sweetie."But Ally doesn't have to pee, she's got to poop and she doesn't want to do it in a diaper! Ally struggles against the ties, wriggling as her tummy starts to ache. She can't hold it any more! Soon a huge poopy is filling up her diaper and to Ally's surprise, it actually feels good in there!
