"That's it," he growled, approval rumbling through the water, his fingers pressing more insistently against the parting scales. "That's it, let me in. Open for me. You're doing so well."
The vent parted fully with a sensation that made me cry out—equal parts relief and overwhelming need. The soft, sensitive flesh hidden beneath my scales was exposed now, swollen and aching, desperate to be touched. The water rushed against me there, cool and strange, and I whimpered at the intensity of it. I looked down at myself, curious despite the fog of need clouding my mind. The vent was a vertical slit in my scales, perhaps six inches long, the edges slightly darker than the surrounding scales. The flesh inside was pink and glistening, so different from the scales that protected it, and when Kaelan's fingers stroked along the opening, I nearly screamed with pleasure.
"So beautiful," he murmured, spreading the folds gently with his fingers, exposing me further. "Look at you. So wet for me already. So ready." His fingers explored the newly opened slit, stroking along the delicate folds, learning the shape of me. Every touch sent lightning crackling through my nerves, pleasure building with devastating speed. He traced my outer folds, learning their shape, then pressed gently inward to find the slick passage hidden within. When one finger pressed inside, I nearly came apart then and there. The sensation was overwhelming—the stretch, the fullness, the slide of his finger against walls that had never been touched. He pressed deeper, curling his finger, and found a spot that made stars explode behind my eyes.
"So tight," he murmured, his finger curling against that spot with devastating precision, stroking it with slow, deliberate movements. "So responsive. I can feel you clenching around me already. You're going to feel incredible wrapped around me."
He added a second finger, stretching me further, scissoring them apart to open me up. The slight burn of the stretch only added to the pleasure, and I found myself pushing back against his hand, trying to take him deeper. His thumb found a sensitive bundle of nerves at the top of my vent—hidden until now, but exquisitely sensitive—and pressed against it with perfect pressure.
"Please," I keened, my hands scrambling at his shoulders, my tail thrashing in the water. "Kaelan, please—I need more—I need you—" The circling stopped. I was dimly aware of the others drawing closer, forming a protective ring around us, their growls and clicks filling the water with a symphony of primal sound. They were watching, waiting, their eyes fixed on us as Kaelan prepared to claim me.
I watched, breathless, as Kaelan's own vent parted. A seam in his tail, similar to mine but positioned slightly differently, opened to reveal his arousal. And what emerged was... nothing like a human. It was massive—easily twice the length of any human alpha, thick and heavy and intimidating. The color was darker than his tail, almost black with hints of deep blue, and it curved slightly as it emerged fully from his vent. But what struck me most was the texture—the surface wasn't smooth but ridged, with raised spiraling lines that ran from base to tapered tip, creating a pattern that looked almost decorative. The ridges varied in size—smaller near the tip, larger near the base—and they caught the bioluminescent light in ways that made themseem almost alive. At the very base, I could see a slight swelling, dormant for now—his knot, waiting to lock us together.
"I know it's different," he said, watching my face with a hint of uncertainty in his ancient eyes, his length twitching slightly under my gaze. "Siren anatomy isn't like?—"
"It's perfect," I interrupted, reaching down to wrap my hand around him. He hissed at the contact, his hips jerking forward involuntarily, and I marveled at the feel of him—hot despite the cool water, impossibly hard beneath the textured surface. The ridges pressed against my palm as I stroked him experimentally, and I felt each one catch against my skin with delicious friction. "You're perfect."
His composure cracked. With a growl that echoed through the water, vibrating against my very bones, he positioned himself at my newly opened vent, the tapered tip pressing against my entrance. I could feel the first ridge catching against my sensitive flesh, and I moaned with anticipation, my body clenching around nothing, desperate to be filled.
"Hold onto me," he commanded, and I obeyed, wrapping my arms around his neck, my tail twining with his so we were connected along our entire lengths. His scales slid against mine, adding another layer of sensation, another form of intimacy.
"I've waited centuries for this," he breathed against my ear, the tapered tip of him pressing more firmly against my entrance, just beginning to part my folds. "Centuries alone in the dark. And you're worth every single second of waiting."
Then he pushed inside, and the world shattered. The stretch was immense—his tapered tip slid in easily, but each subsequent inch brought a new ridge, a new challenge. The first ridge caught at my entrance, stretching me around its width before popping inside, and I gasped at the sensation—a momentary pressure and then fullness, over and over as he pressed deeper.
He sank into me slowly, giving me time to adjust to each new ridge, each additional inch. I could feel them all—could count them as they pressed inside me, each one stretching me slightly wider than the last. Five ridges, six, seven—I lost count as the sensations overwhelmed me, pleasure and pressure and the most incredible fullness I'd ever experienced. When the final ridge slipped inside, when he was fully seated with his hips pressed against my vent, I was trembling in his arms, gasping water through my gills, my entire body alight with sensation. I had never felt so full, so complete, so thoroughly claimed.
"Breathe," he murmured, holding himself still, his jaw clenched with the effort of restraint. "Let your body adjust. Feel me inside you." I could feel every ridge pressing against my inner walls, could feel the slight curve of him hitting places I didn't know existed. When I clenched around him experimentally, he groaned, a deep rumble vibrating through his chest, and I felt the ridges shift inside me, creating new friction, new pleasure.
"You feel incredible," he groaned, his forehead pressed to mine, his dark eyes burning into mine from inches away. "So tight. So wet. So perfect. Like you were made for me." He began to move, pulling out slowly, and I felt every ridge drag against my sensitive walls. The sensation was indescribable—each ridge catching, tugging, creating friction that made my back arch. When he thrust back in, the ridges slid in the opposite direction, hitting new spots, creating new sparks of pleasure.
"Oh gods," I gasped, my nails digging into his shoulders, my tail tightening around his. "Kaelan—I can feel—every?—"
"I know," he growled, his thrusts growing more rhythmic, more purposeful. "You can feel every ridge, can't you? Feel them stroking inside you, finding every sensitive spot, making you come apart around me." The others circled faster now, their growls growing more intense, the clicking sounds becomingalmost frantic. I could see their vents parting, could see their own arousals emerging as they watched Kaelan claim me—each one massive, each one ridged, each one twitching with need. The knowledge that they were watching, that they would all have me, sent another wave of heat pulsing through my core.
"You're doing so well," Kaelan growled against my throat, his thrusts growing faster, harder. His hands gripped my hips, tilting them to a new angle, and suddenly the ridges were hitting that spot deep inside me with every stroke. "Taking me so perfectly. My beautiful omega. My mate."
The pleasure built with each thrust, climbing higher and higher. I could feel the pressure gathering in my core, feel my inner walls starting to flutter around him. Every ridge dragged against sensitive flesh, every thrust pushed me closer to the edge.
"I'm going to—" I gasped, unable to finish the sentence, my body clenching around him. "Kaelan, I'm?—"
"Come for me," he commanded, his voice rough with his own approaching climax. His thumb found that sensitive bundle at the top of my vent, pressing hard, and he thrust deep, hitting that spot with devastating precision. "Come on my cock, Lily. Let me feel you."
I shattered. The orgasm ripped through me with devastating force, my inner walls clamping down on his ridged length so hard it almost hurt, my entire body convulsing with pleasure. I keened his name into the water, my back arching, my tail thrashing, every nerve ending firing at once. I felt the ridges pressing against my clenching walls, felt them prolonging the pleasure as my body milked him desperately.
He roared his own completion moments later, the sound a deep alpha rumble that echoed through the water, his hips snapping forward one final time, driving himself as deep as possible. Then I felt it—his knot swelling at the base, growinglarger, pressing against my entrance with insistent pressure. I knew what was coming, had always known this moment would happen, and I relaxed into it, welcoming the stretch as his knot pressed inside me. It locked us together with a fullness that triggered another orgasm without warning. The knot was huge—easily the size of my fist—and it pressed against every sensitive spot at once. I keened again, pleasure crashing through me in waves, my body clenching helplessly around the knot that tied us together.
"That's it," Kaelan groaned against my throat, his body shuddering with the force of his release. "That's it—feel it—feel me filling you—" I could feel him pulsing inside me, feel his release flooding my depths in hot, thick spurts. The knot kept us locked together so that nothing could escape, and the fullness was overwhelming—the pressure of his knot, the ridges pressing against my fluttering walls, the heat of his release coating my insides.
Then came the bite.
His teeth sank into the junction of my neck and shoulder, piercing the skin even underwater, marking me in the most primal way possible. The pain was sharp but brief, transforming almost instantly into pleasure—intense, bone-deep pleasure that triggered yet another orgasm, smaller but no less powerful. I felt myself clenching around him again, felt his cock twitch inside me as my body milked every last drop from him.
More than the physical sensation was what happened inside me. I felt something click into place—a door opening in my mind—and suddenly I could feel him there. His emotions bleeding into mine, becoming part of me. Satisfaction, fierce and primal. Possessiveness, deep and absolute. And overwhelming, devastating love, so intense it brought tears to my eyes even underwater.
"Mine," he growled against my throat, his tongue laving over the fresh mark, soothing the sting with gentle strokes. "My mate. My omega."
"Yours," I agreed, my voice wrecked, my body trembling around the knot that still locked us together. I knew through my heat I would end up marking them back, but now it was their turn.
