In the surf (image story in the description)

As they walked along the beach she slowly began flirting with the edge of the water letting it wash over the toes of her boots and lap at the bottoms of her flared jeans. As they continued along the shore she began pulling him deeper into the surf rolling onto shore. Soon they were wading and when the water was just above their knees she turned, embraced him and they began to kiss. After a moment she let him begin to pull her deeper into the surf. It wasn't long before they were both completely soaked and enjoying another kiss.

Thank you to @Olympia for the start image and inspiration.
