Slender girl with small breasts naked by the river

Sunny day, river bank, and a completely naked slender girl who clearly likes to pose in nature. She slowly undresses right by the water, shows her body without further ado - she just looks at the camera and smiles. Small breasts, flat stomach, long legs - she demonstrates all this easily and naturally. Naked against the background of the river, she either stands knee-deep in the water or lies down on the sand. The final shot is of her lying on her back, hands behind her head, chest open to the sun.
