Zach came home to a human Sara. "So you are still human?"
"Yup. I guessss that doesn't make you a sssnake."
"Sssara, your s's are being emphassssisssed like mine. Oh no!"
Zach looked worried until he saw that Sara was quite please with te fact tgat she was gonna be a snake girl. "Thissss isss ssso exciting." Sara's forked tum stuck out in the air which gave Zach an erection. He watched as fangs grew in Sara's teeth. He saw a flesh tail turn green and then scales scattered along. He became hot when he saw scales crawl up Sara's butt and stopped at her breast.
"Ssssuck me off!!!" Shouted Zach
"Only if you go down on me with your hot tongue."
Sara stuck the pointy oarts of her tongue in the glans of Zach's manhiod which made him cum everywhere. He then mad egood on his end as his tongue went around the snake vagina of Sara.
