The pressure increased

Being close to home, Mai again feels a strong pressure in her anus. With all her force, Mai squeezed her buttocks. She knew she didn't have much time left before she had to empty her bowels, and still tried to stop it, but it was useless.

The pressure was increasing a lot and she still had a long way to go to get home.

Mai thought about her options. She could pull down her panties and go right there, or she could take a chance and keep walking home.
