She sinks deeper

Unable to focus, April could only sit there and watch as her shorts continue to bulge out with the absolutely monstrous dump she was taking; and watch as the quicksand slowly swallowed that bulging bottom. The thick mud's embrace squished her hot mushy load even more against her butt, causing a mudslide of hot shit to slide down her trapped legs. Her anus closed as she regained control over her less-than-full bowels. Her guts continued to bubble but she quickly chalked it up to her sudden nervousness - she was hip-deep in muddy quicksand and there were no signs of her descent slowing either.

But now that she wasn't shitting, she could focus on trying to escape her muddy predicament. Quickly pondering her situation, April could only come up with two options. She could reach out and grab some of the nearby foliage to pull herself out - but there was no guarantee the green would be sturdy enough to help her. Or she could lean back and try to push and lever herself out, at the risk of getting even more stuck.
