Unplanned arousal

As you watch the two rolling in the mud you catch Miss Nolan's eyes suddenly widen in shock, her hands slipping for a moment and dropping her back on top of Simon.

As quickly as she can she rolls off of Simon and the reason for her shock becomes clear, his slacks are showing a rather impressive sized tent in the crotch, Simon's hard on having been pressed against Miss Nolans body.

With the water still pouring down around the two of them, they try one more time to rise, this time getting as far as their knees before the mud forces them to slide into each other.
