You try to struggle, but it's useless. Aquaris pressed her lips against yours, her tongue probing your mouth. You try to resist but you begin to shiver with arousal as you succumb to her spell, a heat growing between your legs as you pull the mermaid closer to you, trying to sate your growing need to mate.
You can't help yourself, the heat between your legs is too intense to resist. You can't get enough of the mermaid's touch, her kiss, her scent. The feel of her lips, her tongue, her body is overwhelming, driving you mad with lust.
You pull her closer, wanting more of her taste, her scent, her touch. The heat within you burns bright, growing in intensity with every moment of contact with the mermaid's lips. You moan softly, lost in the pleasure of it all as the world fades away around you.
All that remains is Aquaris and her touch. Your body yearns for more, wanting desperately to sate your desire. You barely notice as she pulls you into the water, its coolness a stark contrast to the heat within you. She breaks the kiss and you gasp, water filling your mouth, your lungs. You shudder and arch your back as you feel gills open on your neck. Your gills. Your first step on the path to becoming a sea creature.
The water is all you can focus on as you begin to breathe it. It flows into your lungs, cleansing you from the inside. The taste is crisp and fresh, and you feel yourself relaxing, calming. Your vision returns and you gaze at Aquaris with renewed lust. Your eyes take on a bluish hue. Your body, your mind, your soul belong to this woman now. You are hers and she knows it.
"Leave humanity behind, embrace the ocean" she intones, pulling your head to her breast.
"I... I..." you murmur, barely able to speak, overwhelmed by your own desire. She nods and you obey, your mouth opening, lips pressing against the firm skin of her breast, suckling gently, savoring her strange sweet nectar. You reach your fill and release her breast, resting your head against her chest, spent and half asleep, your desires sated for the moment. You feel Velo's soft curves press against your back, her skin warm and with just a hint of scales, and a new wave of arousal and desire floods through you.
"Please, my goddess, let me complete her, let me be her first," Velo asks huskily, her tail caressing you and Aquaris with equal affection. "Let me teach her the ways of the ocean."
Aquaris smiles and nods as Velo pulls you into an embrace. She smiles as you stare into her blue eyes, her black hair gently waving in the currents. Your gills quiver at her touch as she kisses you, her lips soft and warm against yours, her tongue tasting of salt and brine. She wraps her tail around your legs, and it feels warm, soft, and muscular, a sensation that only heightens your arousal.
Velo reaches behind your back, untying your bikini top and it drifts off in the current. After a moment your bottoms are also lost to the sea, and Velo presses against you, her breasts warm and full, her tail curling around you like a lover's arms. You moan as you kiss, feeling her body against yours, the heat building within you again.
Velo whispers "Do you take me, Leaha, to be your lover and your mate, in high tide and low, until the seas run dry and the moon turns to ash?"
"I take you," you murmur.
Velo smiles, and the tip of her tail touches brushes gently against your feet, her rubbing against your legs and coiling around you like a snake, pressing and stroking you. She gently cups your breasts in her hands as she kisses them, her tongue teasing your nipples until they stand firm.
"Do you take me, Velo," you whisper as she runs her tongue across your gills, "to be your lover and your mate, in high tide and low, until the seas run dry and the moon turns to ash?"
Your eyes lock, and her lips brush against yours she completes the oath. "I take you."
Velo kisses you and your mind is filled with visions of the ocean, its vastness and power. The feel of the water, the salt on your lips, the warmth of the sun on your skin. Your memories become a mosaic of images and feelings.
You remember the smell of fresh cut grass, the sun shining down on a baseball game, the wind whipping through your hair as you pedal furiously on your bicycle. You remember coming out to Velo, your heart racing, your palms sweating, not knowing what she would think. You remember her lips on yours, her hands running over your skin as you made love to another woman for the first time. Picking out matching wedding gowns with Velo, both of you laughing and smiling as you dreamed of a future together as her wife.
But the memories feel strange and alien now. They're like echoes of another life, distant and unreachable. You cannot imagine being on land, walking on legs, breathing only air. It feels like a dream, or a movie you watched a long time ago.
Wrapped in the caress of Velo's tail, you feel your bones and muscles shift and warp, your body changing to match your mate. Your legs stretch and lengthen, your smooth skin rippling and changing to iridescent golden scales. Your sex slides to the front as your legs melt together and your new tailfin unfurls Its translucent membrane flexing and curling in the current, you twine your tail with Velo's and slowly sink to the sea floor, relishing the feel of her scaly body against yours.
You lie together on the soft sand, kissing and groping, lost in one another's embrace. The rest of the world fades away and nothing else matters, the gentle sound of the sea the only noise save your mingled moans and sighs. You take her hand and suck on her fingers, then guide her to your quivering slit. She gently slides her fingers inside you, stroking your inner walls, making your body shudder with need as she caresses your most sensitive spots. The heat inside you builds, the pressure becoming almost too much to bear.
"I...I... I can't...hold back..." you whimper.
Velo's blue eyes stare into yours as her lips curl in a mischievous smile, "Do you wish to, my love?" she asks. You nod, the sensation of her tail and her fingers touching you and rubbing you making it impossible to resist. "Then cum," she whispers, kissing you gently as her tail tightens around you, bringing you closer. She knows just where to rub to drive you wild and you gasp and writhe as the pressure within you crests and breaks, waves of ecstasy pulsing through you. Your tail tightens around her's as again and again you orgasm, each climax more intense than the last, Velo expertly drawing out your pleasure until you can't take any more.
Gasping for breath, you lean against Velo as you recover, her tail cradling you lovingly. You slide your hand down the front of her tail and begin stroking the fine scales around her slit. Velo moans as you tease her, her tail quivering in response. You caress her gills with your other hand, making her writhe in delight.
"Now it's your turn, my mate," you whisper in Velo's ear, your voice thick with desire. You slide your fingers inside her, exploring her slick folds, feeling her body tremble with each touch. Velo cries out as you rub her most sensitive spot, her tail clenching around yours as she cums. Her body shudders and convulses, her gills flaring as she gasps for breath.
"Yes, yes!" Velo cries, "need more!" You slide a third finger inside her as she tightens around you, her inner walls squeezing and contracting, her tail clenching in ecstasy. Climax after climax, her body is wracked with pleasure. Finally spent, Velo collapses in your arms, her chest heaving, her body limp and trembling. You hold her close as you lie on the sea floor, basking in the afterglow of your lovemaking.
Wrapped in each other's arms, you drift off to sleep.

Aquarius gazed down at Leah and Velo, and smiled at her handiwork. These two had held such promise, but even she was taken aback at the what their transformation into mermaids had unleashed. The raw passion on display, the way their bodies twined together, all reminded her of how long it had been since she had felt the touch of another. She gently stroked her new subjects' faces as they slept. Perhaps when they awoke, she could persuade them to frolic with her for a time, before finding new sisters to join them.
"Sleep well, my concubines," she whispered, "when you awake we will have much to do." She planted a gentle kiss on Leah and Velo's foreheads and settled onto the seabed beside them, basking in the warmth of their bodies, and soon she drifted off to sleep.
