It starts raining

They both start to feel the rain come down hard after a few minutes but neither gave it a second thought. After 20 minutes of swimming they both get bored and swim to the steep muddy incline and realized that it's going to be very hard to get back up to their bikes... They soon realized that it wasn't actually going to be possible. They were both stuck in a large puddle and couldn't get up until the rain stopped. It was a Shallow puddle so Sam who was covered in mud at this point leaned down and splashed her pussy clean and told Chris to fuck her in the mud.
