Mary found herself sinking into another quicksand, the traditional way: just walking along, and then it happened. Again. But this time, she had every reason to believe that the ground in front of her was solid and stable. Because the ground was like damn concrete! Unfortunately, it hadn't had time to harden. But concrete is too heavy to suck you down, right? Well, there may be exceptions, if it's a special grade of concrete.

Mary struggled and resisted sinking into the grey mud. She moved so vigorously that her tits were completely exposed. Despite her efforts, she sank lower with each movement. Eventually, Mary sank beneath the surface, although she continued to struggle desperately.

In the bonus video, Mary dives into the mud several times, then emerges and escapes from the quicksand trap.

Note: This is a fantasy scene intended to entertain fans of women in peril. Nobody was harmed during the filming of this scene.
