Chapter Text
Malcolm, in all his thirty two years, had never seen something the likes of this.
Sure, the omega only been living in his little cabin by the sea for the past three years, but you would have thought he’d seen a giant fucking merman before if it was a constant occurrence.
“Okay, uh,” Malcolm muttered, kneeling down cautiously next to the massive merman, casting his eyes over the tanned merman’s upper torso and his long, brown lower half, along his fins and the width of his tail. “Minor scrapes…no big wounds as far as I can see…So why are you beached here?”
The unconscious merman did not answer him, unfortunately.
Malcolm huffed faintly, and glanced the merman’s face, pausing as he tentatively reached out and brushed the merman’s hair out of the being’s face.
His breath caught in his throat, as the merman stirred, and his eyes slid open, revealing themselves to be a beautiful shade of hazel.
Hazel meet pale blue, and something inside Malcolm stirred, crowing in delight.
“…Ah, hello.” Malcolm greeted softly, startling when the merman lifted himself up slightly, his gaze intense. Malcolm couldn’t help but whimper softly, as he realized the merman was, amazingly, an Alpha, and not just that, the most attractive smelling Alpha he’d ever seen.
For a moment, they stared at each other, their only audience the gentle lapping waves of the Atlantic Ocean.
“You haven’t attacked me.” The merman spoke suddenly, causing Malcolm to startle again.
“…Was I supposed to?” Malcolm asked, after a moment, more than a little dumbfounded.
His words made the alpha chuckle, and Malcolm couldn’t help but shiver, the deep rumble of the being’s voice sending tingles down his spine.
“My name is Halsin,” The merman said softly, tilting his head as he studied Malcolm.
Halsin.
The name echoed in his mind, bouncing around as something inside him burned with feverish glee.
“…My name is Malcolm.” Malcolm offered back shyly, flushing at the pleased look on Halsin’s face. “Um, forgive me if I’m being rude, but how do you know English?”
“You are not the first human to speak to me,” Halsin admitted, “But it has been many years since.” The merman tilted his head again, seeming to subtly scent the air.
Malcolm squirmed at the way Halsin was looking at him, feeling heat blossom in his lower naval, and he pressed his thighs together, biting down on his bottom lip.
Now that he was studying him, Malcolm realized that Halsin had to be a Sea Lion merman, his lower half reminiscent of every sea lion he’d ever seen.
“Hmm…” Malcolm squeaked as he realized Halsin was moving closer, practically looming over him. “Your scent…you smell like an aroused female.” Halsin rumbled with intrigue, gazing at Malcolm inquisitively.
“Ah…I was born female, but transitioned to male…it’s called being transgender…” Malcolm explained stupidly, his breath hitching as Halsin leaned in, his pale eyes widening. “I’m…I’m also an Omega…”
“You smell amazing.” Halsin murmured, bowing his head to scent Malcolm’s neck, causing the omega to keen softly, his hands flying up to clutch at the merman’s shoulders, as he felt his insides quiver, feeling a fresh gush of slick soak his underwear. “Hells, I can smell how wet you are for me, little omega. You are so much smaller than I…”
“Oh, fuck-“ Malcolm whined, trembling when Halsin nipped at his scent gland, his blunt nails digging into the merman’s shoulders, his head swimming with want. “P-Please-“
Halsin groaned, a guttural noise that went straight to Malcolm’s cunt, and his hands fell to Malcolm’s waist, tearing impatiently at his shorts.
Malcolm gasped, as the fabric covering him tore under the merman’s strong hands, his underwear a casualty as well, and he moaned as he felt Halsin’s massive hand cup his mound, his hips twitching involuntarily.
“So wet already,” Halsin chuckled, leaning down to kiss Malcolm deeply, the man keening and gasping into his mouth. “You act like you’ve never been touched before, little omega.”
“I-I haven’t,” Malcolm admitted sheepishly, blinking at the rough, pleased growl that came from the alpha’s throat, and he let out a surprised yelp as the Alpha surged down, his hands flying down to grasp at Halsin’s hair as the merman dragged his tongue across Malcolm’s clit. “Oh, oh fuck-“
The merman sucked down hard on Malcolm’s throbbing clit, making the man wail and arch off the ground, fresh slick gushing out of his twitching hole.
Halsin moved from Malcolm’s clit to his hole, his tongue diving in eagerly, groaning at the taste of the omega, hiking Malcolm’s legs over his shoulders as he ate the man out like he was starving.
Malcolm distantly marveled at the size difference between them, the merman’s hands could close around his waist and almost overlap!
He keened weakly in disappointment as Halsin pulled free from between his legs, blinking blearily up at the alpha merman as Halsin picked him up and situated Malcolm so he was laying atop Halsin, with his back against Halsin’s front.
“W-what are you- Oh fuck!” Malcolm’s eyes shot down between his legs, gawping at the long, seemingly prehensile tendril coming out of a slit in Halsin’s lower half, the head of it rubbing against the lips of Malcolm’s cunt.
“Are you ready, little omega?” Halsin purred against his hair, growling softly as his cock ground against Malcolm’s hole, the man whimpering and squirming, Halsin’s hand’s easily holding him up with his grip under Malcolm’s thighs.
“Oh, fuck…” Malcolm bit down on his bottom lip, shivering as the tip of Halsin’s cock rubbed against his entrance, his breath hitching in his throat. This was insane, he couldn’t believe things had gotten this far, he had to stop…
“P-Please, fuck me!” Malcolm begged, only for his back to arch taut, his mouth dropping open as the alpha’s slick, tendril cock abruptly drilled into him, slick and warm and reaching so deep inside him he felt like he was going to die. “O-Oh my f-fucking g-god-“
“Oh, Malcolm…that’s only half of it in,” Halsin grunted, letting loose a ragged breath against Malcolm’s hair, and Malcolm let out a shrill whine, spasming and gasping as more of Halsin’s cock slithered inside him, sliding against places that had never been touched before.
“G-God-t-there’s so-so much, ohhhh fuck I can feel it w-WIGGLING!” Malcolm keened helplessly, his toes curling in his sandals as he arched and squirmed in Halsin’s grip, the omega unable to stop himself from clenching down on Halsin’s cock.
“Oh, omega, you’re taking me so well~” Halsin groaned, as his cock flexed and moved inside Malcolm, the alpha merman mouthing at Malcolm’s neck, teasing at his scent gland.
“G-God-“ Malcolm whimpered, one arm tising up to wrap around the back of Halsin’s neck, his body jolting and arching as the merman fucked him with his strange, wonderful cock. “P-Please-“
“Anything, little omega, I’ll give you anything and everything-“ Halsin muttered almost manically, his cock squirming and thrusting faster up into Malcolm’s cunt, panting against the flesh of Malcolm’s neck.
Malcolm felt that familiar drawing, tightening sensation in his navel, and he whined, his breath hitching in his throat, “I-I’m gonna-“
“Yes,” Halsin sank his teeth into Malcolm’s neck, just above his scent gland, not actually claiming the Omega, not yet anyways, “Come for me, Malcolm!”
Malcolm’s head snapped back against Halsin’s shoulder, and he SCREAMED, his body spasming and his cunt clenching down on Halsin’s wonderfully alien cock.
Halsin all but roared, and suddenly his cock seemed to almost swell, writhing inside of Malcolm who wailed as he felt himself being flooded with the the massive alpha merman’s seed.
Malcolm squirmed weakly, panting and shuddering as he tried to recover from the mind blowing orgasm he’d just had, faintly aware of the way the massive merman was gently petting his stomach.
“Holy…holy shit.” Malcolm mumbled, making a soft noise as Halsin nipped at his ear, feeling the massive merman’s seed begin to drip out past Halsin’s cock. “I…Would it be strange to ask if we could do that again?”
“Not at all, little omega.” Halsin chuckled, nosing at his hair affectionately.
