“Wow! My grandmother had a tortoiseshell hairbrush! I’m glad they made harvesting them illegal, Marcel.” Then I spied a huge pink fan, waving gently in the slight current that ran through the castle. “What’s that?”

“That’s a beautiful animal called a sea fan. They’re related to coral and jellyfish. Her name is Fiona, and she’s engaged to a seahorse named Trigger.”

Ahead of me, I saw a big throne with a merman sitting on it, one of his arms holding a trident, the other cuddling a tiny baby mermaid on his lap.

“That’s the Mer-King of this part of the ocean. His name is Marius, and that’s his baby daughter, Polly. Her mother is the queen consort, Aubrine. Of course, he has many other consorts, but Aubrine is his main squeeze, and he is hers.”

I looked at Marcel in astonishment. “So, he has lots of wives, but do they get to have sex with other mermen when they want to?”

“Well, of course they do, Audrey. There is no jealousy among the merfolk. Everyone shares everything. For instance, you might choose me for your mate, if that’s what you desire, but you could fuck any sea creature that strikes your fancy, anytime!”

“But how would I know who would want to fuck me?”

“Darling girl, everybody will want to fuck you, providing, of course, that you want them to. Consent is all important! Look, let’s try it. Look around and see if someone appeals to you.”

I was sure I was blushing, but I surreptitiously looked around me and soon saw a merman with a very large trident. He was looking my way. “Him?” I whispered.

Marcel grinned. “Great choice, sweetheart. That’s Clyde. He’s handsome and kind, but not, I’m afraid, intelligent. But, as a sex partner? He’s perfect for your first tryst as a mermaid.”

Marcel swam over to the merman without another word. The beautiful man grinned and followed him back to where I swam in waves of embarrassment. “Clyde, Audrey would like to have you as her first fuck as a mermaid.”

Clyde looked so pleased, I lost some of my shyness.

“Pretty Audrey, will you allow me to show you the joys and delights of mer-sex?” he asked.

“Um... Of course. I think I’d like it very much.”

“Would you like to be mounted here? Or in a private room?” Clyde asked me.

I looked around and realized the crowd of merfolk were all watching and waiting for my answer.

“I think that, for my first time, I’d like it to be private. Except, could Marcel come in with us?” I’d already had sex with Marcel, and I felt safe with him.

Marcel looked very pleased, and Clyde was smiling. “Of course, if Marcel wants to.”

So, we three waved goodbyes to the throng, and the two mermen led me down a corridor to a small but beautiful room. It contained a bed shaped like a giant conch-shell, and a tall sloping bench with a top that was padded with more natural sponge. I knew instinctively whatthatwas for.

Marcel flopped down on the bed and prepared to watch me get railed.

Clyde gently arranged me on the bench on my back, with my hips raised and my tail bent down towards the floor. He thenasked permission to hold my hands above my head, so I was immovable.

“For your first time, you’ll have a better experience if you’re immobilized. The thrusting is very intense, and it’s easier if you have something to rest against. Of course, Marcel could hold you, if you prefer.”

I looked at Marcel, and he nodded, so I told him I’d like that.

The next thing I knew, Marcel was kneeling behind me, holding my torso against his chest, and his two hands were on either side of my shoulders.

Clyde hovered over my body, as a cock the size of a baseball bat was aimed at my new orifice. I didn’t have time to do more than squeak before the huge appendage was thrusting into my... mer-pussy? It felt amazing!

Clyde’s cock, like Marcel’s, had scales that slid and grated depending on whether it was entering or exiting my mer-pussy. His giant tail swished to keep him steady in the current and helped him ram his giant dick into me. One of his huge hands played with my breasts, while the other held onto the bench, bracing his body against the gentle current. All-in-all, it was an amazing experience.

When he finally shot his seed into me and withdrew his penis, I was coming for the third or fourth time. Marcel got up from the bed and took his place at the end of the bench.

“My turn,” he growled, then an extraordinary change took place: Marcel the merman became Marcel the dolphin! Marcel as a dolphin was quite a bit bigger than Marcel as a merman, and he hadn’t been small then. At first, I was alarmed as this twelve-foot-long shape hovered over me, and then I became excited as he gently nuzzled under my body until I was floating. His rostrum (as I later learned his mouth was called) nipped my breasts, and his lovely prehensile penis swiveled and groped and finally grabbed my fishy vagina. Our bodies linked, we revolvedtogether in the warm water. My arms tried to encircle him, but his body was far bigger than mine. Nonetheless, he kept us linked together as his member pulsed inside of me, each thrust causing my mer-pussy to spasm in ecstasy. I held on to his flippers, and the sensations that permeated my body were so far from anything I’d ever experienced that I thought I must be dying. I had never come in colors before, but this time, it was as though a rainbow was suffusing my body, and pulses of color and music filled me as I climaxed over and over.

I finally came so hard, I almost passed out. My last coherent thought was that my imagination must be pretty damn good.

I opened my eyes to find myself lying on the bench and a very smug Marcel hovering nearby. He was back in his merman shape, and he smiled and kissed me.
