She releases some poop

Mai relaxed her buttocks slightly, allowing a small load of shit to seep into her panties.

The small charge that drained was viscous, sticky and hot. Mai felt disgusted, but felt she had ****. She couldn't risk running and in a little carelessness all her shit would come out.

Feeling a little less pressure, she moved forward with her thighs together to prevent the shit from coming out of her panties. She walked like a duck and felt ridiculous, but at least she was close to ending all her suffering.

However, she felt something pressing against her anus again, and stopped immediately. She was a few steps away from home, but the pressure against her anus was very strong. Mai just thought it was some fart or something. She thought there would be nothing wrong with letting go the fart and moving forward, but what if it wasn't a fart that was pressing her anus?
