"Sure, why not?" said Mike. "Lets get one of the snakes."
Emily followed Mike to the living room. He carefully retrieved one of his pet snakes, a boa constrictor, from it's tank. He draped the snake over his arms and shoulders.
Emily put the ring with the purple stone on her finger and reached out to pet the snake. As she stroke the snake's head with her hand, the ring began to glow.
"Something's happening!" exclaimed Emily.
"Well, the stone's glowing. But what about you?" asked Mike, still sounding skeptical.
"I'm..." Emily blinked a few times and shook her head. "Everything suddenly looks different."
Mike saw repitilian eyes staring at him "Your eyes..."
"What about my eyessssss?" Emily hissed, punctuating the question by absentmindedly flicked her tongue. A tongue which was suddenly longer and slightly forked.
"Now your tongue too! The ring really works."
"Take yourssssss" said Emily, handing Mike the ring with the green stone. He slipped it into his pocket.
"Don't you want to try it yoursssssself?"
"Later. Right now I want to watch your transformation." Mike stroked the head of the boa constrictor still draped on him.
"My legs feel funny" said Emily. Both of them looked to her legs where brown patches were beginning to form.
"I better ssssit down." Emily sat on the couch, pulling her shoes and socks off. The brown spots were appearing all over her legs.
Mike kneeled down and touched one of the brown areas. "Scales! This is amazing!"
Mike hurriedly returned the boa constrictor to it's tank then returned to stand by the couch. He and Emily both watched the scaley spots appearing on her legs, appearing at random and slowly expanding. Soon her legs where covered in snake scales in colors and pattern nearly identical to the boa constrictor.
"Emily...you look...more beautiful than ever before..." He walked closer to Emily on the couch.
Emily flicked her tongue again and looked up at Mike with surprise. "I can smell your sssscent. I can smell your...lusssst?"
The buldge in his pants apparent as Mike kneeled on the couch, straddling Emily.
"I've always fantisized about a snakewoman" Mike finally admitted. And with that he pressed his lips to Emily's.
