Mermaids in heat

Adella didn't wait. The romantic sister, starving for a real experience, swam forward first. Her trembling hand reached out toward the rigid organs.

"Careful," I warned softly. "They are sensitive. And Shark mating is rough. If they aren't lubricated, those spurs will tear you."

Her fingertips brushed the tip of the left clasper. It jerked in response, pulsing with blood flow. Adella squeaked, pulling her hand back, then immediately reaching out again.

"It's hot," she whispered to her sisters. "Burning hot. And hard... harder than the statue."

I looked at Alana, who was staring with morbid fascination.

"You like textures, Alana. Smooth them for me."

Alana hesitated only a moment. The heat in the water was making her dizzy. She swam down next to Adella.

"How?" Alana asked.

"Use your mouths," Ariel instructed from above, playing the role of the experienced teacher. "Like cleaning a pearl."

Adella didn't need to be told twice. She wrapped her small hands around the base of the left clasper. She leaned in and tentatively opened her mouth, taking the bone-hard tip between her lips. She moaned against it immediately. The taste was alien to her, musky, metallic, and overwhelmingly potent.

Alana took the right one. She was gentler, swirling her tongue around the ridges, exploring the strange, grooved anatomy with clinical, yet highly aroused, curiosity.

The sight of their sisters serving the shark in such a base manner broke something in the others. Arista and Andrina swam closer, their eyes glazed, their tails twitching with envy.

"It's not fair," Arista whined. "They get all the fun."

"There are two," I reminded them, lying back and enjoying the sensation of four royal hands and two royal mouths working on my biology. "And there are seven of you. You'll have to share."

Adella pulled off with a gasp, her lips swollen. "It's... it's throbbing in my mouth. It wants something."

"It wants a vent," I growled.

I looked at Aquata, the timid one hovering in the back.

"You. Come here."

Aquata froze. "M-me?"

"Yes. You're scared. I can smell it. You need to be calmed down."

She slowly swam toward me.

"Turn around," I commanded. "Face your sisters. Lower your tail onto me."

She obeyed, trembling. She drifted down until her blue scales rested on my rough grey stomach.

"Ariel said your skin is rough," Aquata squeaked.

"Feel this," I said.

I raised my massive tail. I brought the thick leading edge of the caudal fin up between her legs. I began to saw it back and forth against her sensitive area. The shagreen skin was like fine-grit sandpaper.

Aquata screamed. It wasn't pain; it was overwhelming, raw sensation. The rough skin rasping against her cloaca was incredibly intense, scratching an itch she didn't know she had.

"Oh! Oh my gods! It’s scratching!"

She bucked against my tail, grinding herself on the rough hide, her shyness evaporating instantly in the face of pure stimulation.

The grotto was dissolving into chaos. Adella and Alana were fighting over who got to lick the claspers. Aquata was riding my tail fin like a wild seahorse. Ariel was watching it all with a smug, satisfied grin.

I looked at Attina, the eldest. She was holding herself apart, trying to maintain dignity, but her tail was thrashing uncontrollably.

"Princess Attina," I rumbled, cutting through the noise of her sisters' moans.

She looked at me, startled.

"As the eldest," I said, my voice silky and dangerous, "it is your duty to ensure the alliance is sealed properly. Your sisters are playing. But you..."

I sat up slightly, scattering the mermaids attending to my lap. The two claspers stood rigid, fully primed, glistening in the violet light.

"...you are going to take the lead."

Attina swallowed hard. The responsibility, and the undeniable, crushing lust, washed over her. She nodded slowly.

"Yes," she whispered, unpinning her golden tiara and letting it drift to the sponge floor. "Yes, Master."
