Leah knew what she had to do. She had to go home. Sure, she could go look for the swimsuit first, but the more time she spent here, the more likely she was to be seen and accosted. She could look up the place she got the swimsuit from at home.
Leah walked, or rather toddled, over to the stairs. To her relief, she couldn’t hear any voices downstairs. Everyone, including the adults, must be outside. Now was her chance. She went down the stairs, her movements and speed hampered by the diaper. As she moved, her diaper rustled loudly. She had no doubts that, if there were any adults around, they would have heard her.
When she got to the first floor, she felt a growing pressure in her bladder. Drinking as much as she had earlier was a mistake. She crossed her legs, trying to hold it in, but it was useless. There was a bathroom on the first floor, but if she took a detour to use it, she might lose her opportunity to sneak out without being seen.
As she squirmed, Leah’s diaper rustled, reminding her that she was effectively wearing a bathroom. She could just go in her diaper if she didn’t want to risk her chance to leave. But the very idea was off-putting to her. The pressure in her bladder grew. She needed to make her decision now.
