Using an Emergency Diaper
When the bathroom is in use, Alisha has no other option but to relieve herself in a diaper in this video.
Olivia and Alisha race to the bathroom, both desperate to pee, but Olivia gets there first and locks the door behind her. Luckily, Alisha is prepared for this kind of situation. Waiting, just outside the bathroom door, is an emergency diaper. Alisha quickly puts it on, just in time, and relieves herself.
