Her hand was now on my leg, or was it? Something felt different. I had gone back into the pool with my wetsuit still on, but it felt like Amanda was touching my skin directly. Then I felt my feet flap against the side of the pool. And realized they weren't feet - I had a tail now! Amanda's kiss had succeeding in turning me into a merman. We pressed together against the side of pool, tail against tail, and I lost myself in the waves of passion...
Some time later, we were laying on the bottom of the pool facing each other. A worried thought crossed my mind. "Amanda, how did you get your tail?"
"You used your ring to make my bikini transform me into a mermaid of course! Why do you ask, Joe?"
I sighed in relief, causing a long stream of bubbles to come out of my mouth. "I was worried you might have mentally become a mermaid too. That you didn't realize who you were or what you were doing."
"I knew exactly what I was doing. I always felt shy and restrained as a normal person. As a mermaid, I felt more at ease with myself. More free. And secretly I always wanted to make love as a mermaid. But I was too embarrassed to say that before now. But when you came back in without your scuba gear, I went for it - took my top off and did my best seduction routine."
"And it was pretty impressive. It helps that you're so beautiful. But I wonder why taking the top off didn't undo the transformation? You're supposed to be a mermaid as long as you wear the bikini, all of it."
Amanda smiled mischievously. "Your exact words were 'I wish the bikini in Amanda's hands turn those who wear it into a mermaid only while it is worn'. You never actually wished for the whole bikini to be needed."
I thought back and realized she was right. "Oh. I guess it worked out okay though" I said with a smile. "Are you ready to get out of the pool?"
"I suppose we should. I have work in the morning. It must be getting late. I wish we didn't have to leave."
It was my turn for a mischievous grin. "We don't." I though very carefully and made a wish. I pushed myself off from the bottom of the pool and floated toward Amanda. She lay back on the bottom as I floated on top of her. "Thanks to the ring, we have all the time in the world." I could feel her sexual energy radiating from her tail again. The feelings of lust and love swept over me like a tidal wave. Our lips met, our tails entwined, and the ecstasy began again.
