"...use that ring to make a matching pair?" Amanda raised her eyebrows to emphasize the point and reclined on her elbow, tail flapping gently in the sand.
"You mean turn myself into a merman?"
"Why not? If you're right and I'll never need to replace the underwear that this thing tore up," she ran a webbed hand along the length of her thigh, "then I'm not spending the rest of my life curled up in your bathtub!"
This gave me cause to think and I truned things over in my mind as Amanda did the best she could to convince me she was right. She rolled onto her front and then laid on her back, the white sand of the beach clinging to her breasts and her hair tousled by the combination of the sudden transformation and the arrival on the beach. If what I suspected was right, then the ring would have no power to grant that wish unless I truly wanted it myself. It was in that moment of indecision that I removed the ring and handed it to Amanda.
"If that's one of your fondest wishes, then go ahead."
"I wish you were a merman," Amanda spoke the words without hesitation the second the ring was on her finger.
Aware of the nature of the transformation, Amanda had me lay down uon the sand next to her and began to help me strip. Her webbed hands were still dexterous and made short work of my shirt before attending to me belt and jeans whilst I disposed of my shoes. As she moved in close to pull the jeans away from my body, our lips met and I felt the smooth warmth of her tail against my legs.
Perhaps she had been siezed by her apetites in that moment, or maybe she had sought to distract my attention from the changes that I was now aware of. Either way my own libido was not at all foxed by the unusual shape and texture of the mermaid's form and I held her to me with both arms as I felt the muscles and endons in my legs shift and begin rearrange themselves. I saw nothing of the transformation, my attention distracted by the feeling of Amanda's hands and their webbing teasing my body.
It may seem odd to say, but there was no great climactic moment when I was aware that the change was complete, so totally had my mermaid managed to distract me. At last I was distracted by the feeling of my jeans still bunched up around my feet, but of course when I looked down I discovered that it was my tailfin they were entagled in.
Taken with the thing, I flipped them away and admired the tail that Amanda had given me. The starnge thing was that while Amanda's tail was shapely and accentuated her charms, my own was fundamentaly the same and yet masculine at the same time. Broader and more muscular, the scales were a shade darker and I thought that we contrasted well.
I put my newly webbed hands around Amanda's scaled buttocks and pulled her into me as the tide began to wash around us.
"Well, what do we do now?" I asked.
