The knot would not come loose

Chelsea fiddled with the knot of her sweatpants, but in her nerves she could not let go, the knot was too tight.

Chelsea stood up so as not to put so much pressure on her belly and squeezed her buttocks as hard as possible. She had to loosen the knot so she could pull down her sweatpants, but the knot did not cooperate, and her nerves and despair grew greatly.

She tried to pull down her sweatpants without letting go of the knot, but it was so tight at the waist that she couldn't pull it down, so she had **** but to try to loosen the knot.

Chelsea even tried to let go of the knot with her teeth, but the knot wouldn't yield to anything.

She felt her anus open and let loose a flurry of wet, bubbly, smelly farts, that was the last sign before disaster struck.

Chelsea moved her fingers anxiously, feeling that her excrement was already at the exit of her anus.
