"Well, I'm not planning on going anywhere soon," Amanda smiled.
Without a word I let instinct take over and slipped around behind her in the mounting surf. It was safe to say that sex between merfolk was something neither of us had any experience of, but luckily for me that didn't seem to be an impediment as our scales met, her buttocks to my lap.
One hand slipped over Amanda's breasts whilst the other revelled in the texture of her tail, tracing the shape of the scales at the same time as feeling the webbing newly grown between my own fingers.
The anatomical design of the merfolk seemed to favour the hiding of the sexual organs until such a moment as this. Until that moment, Amanda's buttocks had been firmly held together. Bit now as she became aroused they parted gradualy and allowed entry.
My own body had retained the male organs out in front, but again secreted them away in a well hidden cleft covered by my scales. But like Amanda there was no way that I was keeping them hidden any longer. My own member may have emerged changed by my transformation into a merman, but I never saw it, only felt as it found its way home.
We made love there on the beach, our bodies pressing down into the wet sand and the feeling of ecstasy was matched by the sensation of the mermaid's tail, Amanda's tail beating against my own.
When it was over we lay there in the ebbing tide and I willed the waters to wash us away forever.
"I'd offer you a cigarette," Amanda laughed as she sat up and stretched, her breats still covered in wet sand, "but I think my last packet got a little wet. Nasty habit anyway."
"Human habit," I corrected her, "so how do you like being a mermaid now?"
