No sooner than she took the picture into her hand, it mere moments later faded away into nothingness. It seemed to be some sort of fish... a trout, or a salmon perhaps? She shook her head and headed up to the surface. She swam to the shore, and crawled onto the small beach opposite the waterfall.
Resting on her back, her elbows propping her up, the girl looked around her. Was she truly alone? No one seemed to be near, and she had suddenly started to feel quite aroused. Biting her started exploring her own body and smirking wickedly, her hands soon started exploring her body, caressing and pinching her delicate and fair skin, almost glistening from the water droplets adorning her body. She gave her tits a squeeze as one of her hands reached her mound in between her legs. She coaxed a moan out of her mouth, as her eyes rolled back in her skull. Masturbating... outside! Someone could be watching...
While she was fingering herself, she didn't notice that she'd started to change. In between her fingers, the skin began to grow longer, until her hands were webbed to the second knuckle. In between her toes, the same process took place, her feet also becoming slightly wider making room for the webbing between her toes. Along her skin, random patches began to glisten quite a lot. Not from sweat, but from something growing from it. Smooth scales made themselves known in small patches across her shoulders thighs, and under her tits. Too preoccupied to see her changes, she soon reached her climax. She wailed and moaned, writhing about on the ground. Panting for air, she made her best efforts to recover.
