The setting sun, part 1 of 3

Shannon had talked her into going out on the beach to watch the sunset before they left to meet their other friends for the night's festivities. Jen had been reluctant but eventually gave in and followed Shannon out to the water's edge to watch the setting sun. But soon Jen realized Shannon had an anterior motive as she grabbed her hands and began to playfully pull her into the water. At first Jen played along, her sandles and bottom of her jeans would dry eventually, but Shannon kept going further in and as they giggled and laughed Jen tried to resist and battle against getting pulled into the waves and ending up soaked like Shannon was suggesting...
