"You're a mermaid!" Tim exclaimed. He looked his girlfriend over before adding "You're beautiful."
Janine beamed. She hadn't really thought about how her boyfriend would react; all she thought about was transforming into a mermaid. "I'm not usually beautiful?" she teased.
"You've always been beautiful, but now..."
Janine noticed Tim's pants were looking a little tight. Nothing she'd ever done before had got him turned on so fast. Tim leaned in and kissed her passionately.
When their lips finally parted Janine said "You know, we could go somewhere more comfortable than the living room floor..."
"Good idea" Tim said.
He pulled off the remains of Janine's clothing that had been ripped and torn by the transformation, giving them both the full view of her mermaid form and the green fish tail that had replaced her legs from the waist down. Scooping her up, Tim carried Janine into their bedroom and, after another kiss, deposited her gently on their king-sized waterbed there. The feeling of floating seemed better than usual to Janine.
Still dressed from work, Tim hurried to undress at the bedside. He had gotten his shoes and shirt off, when Janine decieded she could wait no longer. She grabbed Tim gently by the belt and pulled him onto the bed with her. They kissed and fumbled to remove his pants and underwear. Tim found the feeling of Janine's fishtail between his legs to be a little strange yet very erotic.
