Fifteen miles Southeast of Santorini bound for Malta, and they'd been footing along through the clear Mediterranean waters at around 3.5 knots in a light breeze when Belinda first spotted her, moving through the ocean gracefully like a fish.
Chip had lucked out in more ways than one. He'd been in the right place at the right time and his tech startup had ballooned almost overnight. He'd sold out on top, and with fat stacks of cash now safely invested, was pretty much set for life. Belinda and he had decided to retire early and chase the dream of circumnavigating the world on a sailboat.
"Chip. Come up here. What *is* that?" Belinda shouted down the companionway of the boat.
Coming up on deck, it was obvious that he saw it too. "Damned if I know. Never seen anything like it."
Belinda waved at it, and it altered course. It had seen them and was heading towards them on an intercept course. It swam with the fluidity of a porpoise coming up alongside the port quarter and breaking the surface of the water.
"Can I come aboard?" Belinda and Chip heard a very sweet feminine voice say.
"Um.. sure?" Chip replied, lowering the swim ladder.
She climbed dripping into the cockpit, her green hair was long and fine. The sun shone off her skin like it was made of a billion little scales, shimmering as she moved. She was just over five feet tall. Naked, her breasts were small but perky. She smiled, her lips a light bluish color. Her pussy was prominent, smooth, and well formed, her outer labia blue like her lips. Fingers and toes somewhat longer than normal humans and webbed. Oh, and she had gills creasing the sides of her neck. Barely noticeable now that she was out of the water.
"I saw you wave!" She said cheerfully. "So, I swam over to say hello! My name is Beltane."
"I'm Belinda, and this is my husband, Chip. What are you?"
"I think you would call my people Mer." She replied. "We live in the oceans of the world. Usually we keep our distance from humankind."
"So why did you decide not to with us?" Belinda asked.
"Simply that I saw you and thought you were so beautiful. And out here on the ocean sea. I wanted to check you out. So, here I am." Beltane lilted sweetly.
"Well that's very flattering." Belinda replied.
"So, can I take your coverings off of you?" Beltane asked politely.
"That's um... a strange request." Belinda answered.
"Is it? I did not know it was so. I want to see all your skin." Beltane explained.
"We're in the middle of the Ocean, honey. What harm could it do?" Chip chimed in, obviously amused by the exchange.
Chip laughed to himself. His wife was built like Wonder Woman. It had almost been the first thing he'd thought of when they'd first met. He'd made up his mind on the spot to romance the hell out of her...And he had.
Beltane approached Belinda and pushed the waistband of her shorts and panties to the deck. Then clumsily unbuttoned her blouse, removing it, followed by her bra.
"I like all your skin like this." Beltane commented reaching out to touch Belinda's breast. "I have long studied human expressions of pleasure, and I find them fascinating. I would like to learn more." She leaned in and brought her lips to Belinda's nipple.
Chip watched his wife flinch slightly, and then relax, as Beltane continued her explorations. Belinda's boobs were big, but they were also sensitive, and hardwired to her clit. Belinda literally could cum from that stimulation alone, and Chip saw that softening look in her eyes that told him she was quickly getting aroused.
"You taste exotic Miss Belinda." Beltane crooned as she reached around and cupped Belinda's ass cheeks. Pulling her forward, Beltane began kissing her neck and earlobe. Nibbling playfully as she pressed her body against Belinda's chest.
Chip noticed that Belinda's breathing was modulating further and further down the path that indicated she was turned on. Belinda had never been with a girl, but all that was about to change. When Beltane's mouth found hers, almost as a reflex Belinda's arms went around her in a passionate embrace. Chip could feel his cock starting to harden in his shorts.
Beltane eased Belinda down onto the cockpit cushion and next to her they continued making out. Beltane's kisses melting Belinda's resolve as Beltane's fingertips traced the moistening slit of her pussy. Wet, she brought her fingertips to her lips, her narrow coarse fish-like tongue darting out to taste Belinda's musk.
Nodding as if to herself in approval of Belinda's full-on arousal, she slid down onto the cockpit sole and buried her face into Belinda's wetness. Belinda's hands were gently in Beltane's hair, she was breathing in gasps, staring at Chip with unfocussed eyes. Concentrating on Beltane's attentions, she was past the point where she could stop. In fact, she'd never been eaten out like this, and it was driving her wild.
Chip had his cock out and regarded the two...women? Before him. He slowly stroked himself, enjoying the sensual display going on just feet away. Belinda shuddered and shook, cumming over and over again on Beltane's face. Her moans rose and fell as Beltane relentlessly ate her.
After a long while the two women exchanged places. Belinda had always been straight, but that didn't seem to matter now. There was no hesitation on her part as she started to lick Beltane's pussy. Beltane locked her eyes with Chip, a tranquil smile of conquest on her face as she watched him jerking his cock in time to Belindas ministrations.
Beltane began to cum, throwing her head back in abandon as Belinda's tongue sent her into the abyss. Chip's cock exploded onto the cockpit floor. It was the most erotic scene he'd ever witnessed, bar none. The Mer woman's tits heaving as she gasped through a convulsive orgasm.
Out of breath, they all sat there in the cockpit staring in disbelief at each other. The autopilot hummed a little as it adjusted course. Belinda's watch was ending, Chips had begun. Hand in hand the two women disappeared down the companionway into the cabin. A short time later Chip could hear the unmistakable sounds of their passionate union, resuming below.
Other than hearing several rounds of his wife and Beltane's enthused grappling, the watch passed without further note. Belinda was below in the galley throwing together a meal. Beltane watched wide eyed.
