The next morning, Hailey was ready to try out the diaper. She forsook her usual post-awakening trip to the toilet and instead waited until Erin was in the shower.
She shut the bedroom door. She had been looking forward to this opportunity, but now that it was here, she was having last minute doubts. What if I get caught? That was nonsense, though. She had planned this, she was ready, and nobody was going to find out. Erin was busy in the shower, and her parents knew she was old enough that they needed to knock before coming into her bedroom. At this time of the morning, she could believably tell them not to come in because she was getting dressed.
