You swim a little

Once you swim a couple laps around the lake you start to slash her a little with some of the water. And you swim up to her. You get even closer and suddenly you are both kissing inside the water.

After a minute you break it of again.

She looks at the shore...

"Fuck! I think there is somebody out there!"

You look over too. And see a guy walking up to the little shore that's there.
