Stay underwater and keep following her

When Kate gets to the other side, she's exhausted. She climbs out of the water then falls on the muddy ground.

You climb out of the water after her.

When she sees you, she screams and starts crying. She gets up enough to start crawling away from you, but she's not really going anywhere...

You take your time and look at her for a while. All the water and mud has stuck her dress to her fine body. The sight of her crawling away from you, her apple-like ass up in the air gives you an instant hardon.
