Full description: Ava has entered a sexual relationship with the monstrous eel-mermaid, affectionately called "Elidy" by the townsfolk, who inhabits the lake by her cottage. She goes out on her boat most nights to have some fun with her lover; in the dark, while the world sleeps on unaware.
Note: This story contains a relationship between two characters with a language barrier. It is explicitly clear that the two fully understand one another's body language, so no one is being taken advantage of in this scenario.
Both of the characters depicted are consenting adults; Ava is 27 and Elidy is a few centuries old (around Ava's age in human years).
Thank you and enjoy!

Ava waited until nightfall to leave her cottage and drive her boat far out to the middle of the lake. She cut the power but kept the boat's lights on, tossing her anchor overboard and sitting back to wait.
The late-night excursions out onto the water had been going on for a little over a month. Ever since Ava met a local legend dubbed 'Elidy' by the people in the nearby town. Elidy was a lake monster similar to a mermaid, but more monstrous. All cold, shimmering scales and dark, bewitching eyes—very deep sea-like.
Of course, the locals didn't know all the same details that Ava did. Elidy never attacked anyone and sightings were rare, so they had never seen her up close or been nearly as personal. When Ava set out in search of her, she never imagined forming a sexual relationship with the mermaid. Nor did she expect how good the sex would be, and how hooked she would get on it; pun intended.
Ava frequently caught herself dreaming of clawed, talented hands worshiping her breasts and nipples; slick skin glinting in moonlight; a cool mouth at her neck, steadily moving downwards; a long, clever tongue gliding over her stomach, hips, thighs, between her folds. She would awake whimpering, soaked through her pajama bottoms as her pussy throbbed.
In the pale light, Ava stripped off her clothes, kicking off her pants and hastily unbuttoning her blouse. As she finished, she heard the telltale stirring in the water. She smiled as she walked to the back of the boat, looking over the edge in time to see a dark scaly head emerge from the lake. Familiar eyes regarded her. Twin head fins waved in excitement and sent little ripples across the water's surface.
Elidy's full head and shoulders left the water, beads of moisture dripping down her face and neck, pooling in the divots of her collarbone. The slits of her nostrils flared, catching the scent of Ava's arousal. A toothy grin broke out on her face, followed by a series of fond clicks and whines. Easily, she hoisted herself most of the way onto the deck, the majority of her long eel-like tail remaining in the water. Her inky black hair and silvery skin caught the light; ghostly, but radiant.
Where her humanoid torso met the fishy coil of the rest of her there was a noticeable slit. In Elidy's nearly immediate excitement, it split to show her silver, dripping folds and a small, blue, tentacle-like appendage where her clit would be which writhed enticingly.
In an instant, Ava had Elidy in her arms, kissing her fiercely. It was unavoidable that her tongue grazed over sharp teeth, but she knew how to avoid getting cut.
"Fuck, this woman could eat me alive if she wanted to," Ava thought. "Good thing she likes pussy so much."
Elidy's hands were quickly at Ava's back, undoing the clasps on her bra and letting her breasts bounce free. A hand fondled one of them while the other slid down into her panties. Ava gasped as she felt thin fingers rubbing at her pussy, spreading around the already substantial wetness. She couldn't help but grind her hips down against them and a rhythmic, slick sound filled the air as she humped enthusiastically.
Ava returned the favor by bringing her hand to Elidy's slit. The beautiful, twitching hole sucked in two of her fingers greedily. She loved that almost elastic, willing pussy that was always ready to take whatever Ava wanted to give it. The walls pulsed around her with each thrust of her wrist and Elidy began bucking forward, forcing Ava's other bent fingers and half of her hand in as well.
They moaned into each other's mouths—well, Elidy's high-pitched whine rendition of a moan—as spit dribbled down their chins. Ava's legs grew weak and trembled, her movements growing desperate as her body craved more. She pulled away, panting and lowering herself down onto the deck. She was watched intensely as she shimmied out of her now thoroughly soaked panties and tossed them aside. Her legs spread in invitation and she could feel herself dripping.
Elidy clicked affectionately as she settled her head between Ava's legs. She held one of them, slowly kissing her way down from Ava's calf to where her breath ghosted across swollen folds. That irresistible tongue darted out over Elidy's bottom lip before she opened her mouth and extended it to its full five inches. She maintained eye contact as she lightly dragged the tip up Ava's pussy to her clit, swirling it around the sensitive, throbbing bud.
Ava shook and moaned as Elidy repeated the slow, torturous cycle over and over until she finally felt the wet tip at her entrance.
"Please," she begged breathlessly, wiggling her hips. "Please."
