Roshutsu Kaigan Boku to Hadaka no Imouto 4

One summer day I went to the beach with my little sister. She didn't bring a swimsuit, but there was no one to see us. We both got naked. She loved the feel of water on her birthday suit. Seeing the water glisten on her taut youthful body I wanted to play more. We came together. At first she didn't want me to put it in. But whether it was the freeness of the beach or something in her nature, she warmed to the gyrations and welcomed my semen inside.
