    “No. This is as far as I go. You saw those barricades back there. It was sealed from the outside for a reason.”

    “We’ve come this far, I’m not turning back,” you say sternly.

    “It was designed to keep something inside, not to keep people out! Don’t be a fool!”

    You shake your head, “I have to keep going.”

    “Alone,” he says, turning to leave. “If you make it out alive, may we meet again.”

    He was afraid. Now you’re on your own. Down here in the dark, you wander a little bit further, past rock walls that look no different to the ones ten metres back. There’s a pull on you, as you stumble down through the shadows, and it’s not just the allure of the unknown.

    There is a… presence.

    Unsteady flooring that threatens to give way with each step and the humidity hanging in the air make for an uneasy feeling. Turning a sharp corner, followed by another twist, there’s a smell that hits the back of your nose. It’s unusually fresh. Flowery. It’s like spring has invaded your sinuses.

    With another turn, there’s a heat and a faint blue light, as the tunnel widens into a cavernous hollow.

    There it is.

    Water.

    You were expecting more ominous, dingy blackness; rocks and debris, and some dirt, but this is quite the opposite. Crystal clear. A natural underground spring. Glowing crystals in the rocks shine from all directions, providing pale blue shimmers that coat every wall and every crevice. There’s a gentle passage of ripples over the surface, from the very back where water spills in from above.

    You approach the edge and stare into the depths.

    Silent.

    Still.

    Peaceful.

    There’s a stone, not like the others, propped up by the near edge of the pool and upon that is an engraving. Old and moss-covered but still decipherable. You dust it off gently with your fingers and then pull the notebook that was given to you before the search began. Matching symbols to words provides the vaguest of translations, as best you can make it out.

    It speaks of a choice and a world beyond.

    It speaks of the unquenchable thirst of man and the dangers of desire.

    Your breath hangs in the air as you kneel by the water’s edge, your chest heaving with apprehension, a churning sensation swirling in the pit of your stomach, bringing your heart to the back of your throat. You have no idea how long you have knelt at the side. You’ve not taken a single glance upwards, but now the nerves settle, it is the only urge you feel.

    You dip your hand into the water—it’s not hot nor cold, no boiling burns nor icy chill. It’s just lukewarm. Comfortable.

    You dance your fingers below the surface. It feels as though time has ceased its march as you stare at your hand and beyond it to the seemingly bottomless pool. The weight of your body shifts unnaturally as if an unseen energy is pulling you under, beckoning you. It is no longer in question whether you will venture inside the spring, you have no choice but to descend.

    Inhaling deep, eyes closing slowly, you are powerless to resist. Toppling forward, you enter the welcoming water and its tranquillity washes over you like nothing you have ever felt before.

    “It’s been so long.” A voice echoes all around you and your eyes bolt open, there’s nothing there but deep blue and you slam them shut again in fear. “Don’t be afraid. I’m here to give you purpose,” she coos.

    It is as if she is the water itself, the words speak in your ears, her very voice coursing through you. Soothing yet tantalising, dangerous, and entirely divine

    “You sought me. You have found me.”

    You struggle and thrash in the water as panic consumes you, unable to grasp any sort of orientation. There is no up, no down, no surface, nor edge. There’s a tightness in your chest, the need to breathe, but you can’t open your mouth, not down here.

    “Stop moving, you are in safe hands. Trust me and I will keep you afloat. Trust me and you will breathe,” she soothes. “Don’t fight the water, let it carry you.”

    You grow limp, accepting. All you hear are her soft-spoken tones, all you can feel is her embrace around every inch of your body, every curve and crevice and within moments, you succumb. When your lips fall open and you try to take a much-needed breath, it just works. Like it’s second nature.

    “Open your eyes.”

    The naked form of a woman is before you.

    In her flawless human appearance, her long, wavy hair floats effortlessly by her shoulders and her mesmerising smile pierces the depths. Her long legs somehow find purchase on nothing, she walks towards you with ease, unashamed in her bareness.

    She holds out a hand and it calls out for you to rest in her touch, as the weight of your own body carries you down. You settle as she grazes her fingers over your cheek and warmth spreads from her hand, down your spine and into the extremities.

    “Did you read the warning? If so, why did you not heed it? Do you seek pain, torture, death or worse?”

    “No… I,” you mutter.

    “Then are you just a fool?” she smirks. “Blinded by discovery and the thrill of danger? Then I will be honest with you. The world above the surface no longer welcomes you, it has forgotten you now. As it has many people before you.” Her voice is both powerful and alluring. “So, as with every mortal my kind draws into their waters, I offer a choice, two roads, and you must decide.” She brings her other hand to your face, cupping your cheeks between her hands, pressing the tip of her nose against yours and bringing her lips close. “Though it’s not much of a choice.”

    She smirks, and then pushes you down, deeper into the water, and she follows, whisking you in a current that threatens to consume you in its unnatural wake. There’s a harsh change in environment and temperature, from comforting warm and tranquil, to painfully bitter cold. Your limbs start to become heavy and numb, making it harder and harder to fight against the water’s embrace, to kick and reach for anything you can. But there is no escape, only surrender to the inevitable, the unavoidable.

    Then it comes into view, below you, somehow, an island, with grass, trees, and other greenery. There are grand structures littering the landscape that you can barely make out from this height. In any other situation, the beauty that lays far below would be enchanting, but not now.

    “The Isle of Avalon. I’m sure you’ve heard of it. Heard the rumours of how beautiful it is, what a paradise it is,” her voice fills you once again. “You can call it home now. Take what I give and relinquish the rest. Or I can send you out to a world where you are now no longer welcome—where only death awaits.”

    She moves into sight again, her delicate body floating around you, and as soon as she looks into your eyes, you are ensnared once more. She smiles the most innocent, pure smile, yet it fills you with a lust that you cannot describe. Her eyes penetrate deep into your very being, reading your innermost thoughts. You finally muster the most simple of questions, “Who are you?”

    “You know who I am,” she whispers, placing her hand on the side of your head and it awakens in you like a memory.

    “Tzuyu. You’re a water nymph. A protector of Avalon,” you recall from a false memory.

    “And what do I want?”

    “Me,” you admit, somehow knowing that it is true.

    “Only you.”

    Tzuyu’s hands drift along your neck and down your chest, and as she does, your clothes just fall away from your body, seemingly disintegrating into nothing until all that is left is yourself, bare and floating.

    “Choose.”

    “I choose life. I choose the isle of Avalon, if it’s with you,” your lips spill your desires of their own volition and Tzuyu moves closer and closer to you. You fall deeper and deeper into her gaze, her alluring eyes of the deepest hazel are hypnotic and impossible to break free from.

    Your hands find her waist, some semblance of control coming back to you, and she says, “Good choice,” and pulls herself close.

    Your bare body comes flush against hers as she pushes her lips to your own, and her kisses taste like every beautiful thing combined into one. A tinge of wild berry, of sweet chocolate and vanilla. You’re powerless to resist when her tongue slips between your lips. Instinct demands your hands slide down over her waist and across the curves of her ass.

    Fingertips sink into the soft flesh, squeezing with a need you had no idea existed. It seems to please her, the nymph responding in kind by wrapping her long legs around you, cooing delightfully, humming into the kiss. Her hands weave into your hair, tilting her head as she drinks you down with every motion.

    You’re anchored to each other, weightless and swirling in the wake of the waters. Tzuyu pulls slightly from the kiss to tell you, “Hundreds of years, waiting for this. I can hardly bear to wait a second more,” and then your lips meet again.

    Smooth skin rubbing against you as she grinds down against you. The legs in the small of your back pull you tight against her warm embrace. So tantalising lewd is the rough massage against the underside of your cock, she does not even hide that she means to entice your manhood to rise.

    At your ear now, Tzuyu whispers, “The very thought of it sends shivers right through me.” She grinds slowly as she says it as if emphasising her not-so-discreet intention. “But first…” and suddenly, you are falling once more. Down and down. Until you are swallowed by the darkness.

    A slip out of consciousness and then a return, and you awaken on your back. Lying in shallow water of a pool, much different to the one you fell into. Tzuyu is still against you. “Welcome home. Now. Take me.”

    She feels more real now—tangible. Her weight is on you as she pulls her hips over yours and draws your cock up to her entrance. You’ve had her kisses, her touch, but now she gives you the promise of rapture beyond compare.

    Eagerness drives her to simply drop onto your tip, allowing the wet entrance to give way and accept you. From that very first moment, you are surrounded by her, cloyed with pleasure. You feel her thighs tense around your waist, feel the breath gasp out of her lungs, feel her grip clench upon your shoulders with her eyes shut, teeth gritted and brows furrowed. She tries to take you all inside her, pushing and grinding, only to wince as she struggles. Tzuyu does everything she can to relax and savour the slow sensation of letting your hard cock invade her depths.

    “You don’t understand how much I’ve yearned for this,” she coos. “We each had to wait for so long to find a mate but now I have you. Finally, after so long, and I can have you, again and again and again, and you will enjoy having me just the same, won’t you? Can you feel that desire, even now, how much you want to breed me?”

    It is an undeniable truth. So when Tzuyu starts to ride you, her hips snapping down against you and creating a small splash in the water, you thrust back. You fuck into her, every twitch and ripple of her inner walls sending waves of pleasure through you.

    Friction, the smell of the woman who’s above you, the taste of saltwater on her lips, the noises she makes and the pressure as she clamps on your cock. It is hard to focus, and hard not to feel every muscle in you contract and ache from pleasure, as Tzuyu throws herself at you, losing herself in the way your bodies come together, rocking back and forth to her rhythms as you enjoy her and relish letting her have you.

    This paradise is your new home and it welcomes you with the most erotic of experiences. You wish that this moment could stretch to eternity, with her warmth wrapping your shaft, as it throbs and pulsates with a growing pleasure.

    You see her biting down on her bottom lip as her rhythm grows increasingly desperate, and she leans down against you, pressing her breasts to your chest and bracing herself. Feverishly, her hips continue their thrusts, and now with greater speed, deeper, taking every bit of you as if it is necessary for her very survival.

    “Can’t stop. Not until you cum!” she moans. Her body jerks erratically, all but convulsing. Tight. Intense heat. Coaxing you with her body and her moans. The physical pull of her is nearly irresistible and the flood of pleasure seems too much to handle. You grip her, her thigh and her ass, tight, aggressive and relentless. You need to force your hips upward.

    You need to cum inside Tzuyu.

    “Fill me with it,” Tzuyu grunts as her entire body shudders and the water ripples around you.

    Just one more frantic thrust as your hips smack upwards and her back arches in sheer euphoria as she shouts your name, and suddenly the deluge is just too much to hold back. Everything bursts out inside her. You unleash and thrust upwards, over and over, releasing the thick rope after rope into Tzuyu with a raspy moan. And she seems so overjoyed that the more you give to her, the more desperate she becomes as she squeezes you with every muscle she can manage to demand even more.

    Here on the Isle of Avalon, you soon learn that night and day simply don’t exist. Time is not a constraint for the girls who live here, and the men they keep. Here on the Isle of Avalon, there exists only everlasting desire, and one’s ability to fulfil it.

    You become a slave to this need. Resting only to satisfy Tzuyu again when she is ready, and it’s always in the water. The next time you have her, it’s submerged and against the tiled pool wall. Tzuyu pinned against it, her thighs splayed and feet hooking behind the backs of your thighs while your hands squeeze her ass and press her to you. It’s fast and loud and intense and makes every bit of the excitement inside her abundantly apparent.

    You thrust into her and she demands you not be gentle, demanding that you continue until her tight pussy squeezes every inch of you with her orgasm. “Now… Yes. Just like that! Keep fucking me. Take my body,” and when you do just that, she squeals. She moans and she pants, and it all feels so, so good.

    Her plump ass hits against the tiles as the water splashes with every aggressive stroke. You grow closer, every spasm a bit stronger than the last. She screams in absolute ecstasy as you unleash every drop inside her. You know, there will never be a way off of the isle, because Tzuyu has you forever. And there is no way out.

    “I love it when you get a little rough,” she tells you the next time on the soft sand shore. When she turns her back on you and orders, “Mount me,” you sink your cock into her as you always do, because, in this land, her desires are always your own, and there can only ever be pleasure.

    She arches her back and her hands grab the backs of her thighs, urging you to pound her. Urging you to go harder and faster. When her eyes look over her shoulder, she pants your name. Begging you, “Fill my pussy, please. Flood me with it and stay deep in my cunt.”

    Her ass shakes as you thunder against it and grunt. Sweat glistens on the muscles of her back, making her skin gleam. Sand sticks to her chest, occasionally washed by the crashing of a wave and the girl wants it even harder, “More! Don’t stop!” and again, the more she asks, the more you give. The more her fingers sink into the flesh of her thighs and yours into her hips. She thrashes back and forth against your thrusts and you fuck her tight cunt into bliss.

    It feels natural now. Everything. This is the way of the world now, whatever this world is, wherever it is. It’s life in its most raw, natural form. When your seed drips from her quivering cunt onto the sand and she looks over her shoulder and smiles, “Again.”

    So when she shifts onto her back in the shallows and says, “Fuck me. I want you in me again. Please.” It’s just natural.

    It happens all around you, all the other girls, the ones that have secured themselves a human, a tool, to satiate their needs. Even on the very same beach, Nayeon is astride her man, bouncing and shouting. Twisting and swaying and driving him back inside her with lust.

    What would be hours, days, weeks, and months in the life you used to live, all pass in a sex-fuelled, addling blur here.

    Years down the line, you’re still here, on the steps of the pool, where Tzuyu sits and her knees are hooked over your forearms. As your cock drills inside her with relentless thrusts, Tzuyu’s nails score the back of your shoulders while she tosses her head and screams at you not to stop. You still take the request as seriously as ever.

    Every vigorous slam inside, with every bruising collision of your hips against hers, each more tiring than the last in the resistance of the water, it’s all in the effort of making her cum. There isn’t much else that Tzuyu does aside from climax these days, and you do it all for her. It’s all any of the girls do. Even now, barely a metre to your left, Sana sits on the same steps, taking her rough fucking, by an eager man who claims her moans as his lips assault her neck and she bucks in ecstasy beneath his weight.

    This is life, now (and forever), for better or worse.
