Jeff had scrolled through the options before coming up on the option for Snake. He had always wondered what it would be like to have tail instead of legs. Pressing the snake option A list of tabs was brought up, and Jeff filled it out to his specification, setting the time of transformation to last for a year. Leaving everything else random Jeff hit the confirm button and laid back in his chair.
He chair dissapered from underneath him, which sent him flat on his behind to a rocky surface, it seemed he was in a cave at the moment. Glowing mushrooms illuminated the cave just enough to see himself. Getting up Jeff looked at his surroundings, noting that there was a exit into a tunnel system off to the side of the cave, and a small pool of water with fish swimming in it that he could use for food and water.
A sudden tingle in his groin brought Jeff out of his thoughts as he looked down. Eyes wide he watched as his penis shrunk and balls retreated until all that was left was a horizontal slit on his groin, a snake's cloaca.
Touching her new genitals Jeff moaned with pleasure from the contact as a new tingle started up, effecting his legs.
Her legs grew closer together and left her with a single limb, her feet changing I too a simple tail point as her ass smoothed over, leaving her still manly hips connected to her tail. It didn't last long as scales exploded across her flesh tail, over taking it completely and up to her belly button, absorbing it into the scales.
Flicking her tounge out she saw her tongue was former as her upper body started to change, sliming into a girl's figure as two breasts grew on her chest. Two patches of scales formed on her cheeks like freckles and some on her shoulders. Feeling the changes finish the new Naga stood on her tail in the cave.
