The water was cold, as to be expected in the middle of autumn, but Astarion’s entire body was warm as he swam, his lungs screaming, yet he forced himself to continue. He could hear the blood pulsing through his body, a steady drumbeat in his ears to accompany the sound of the seagulls above. There was a presence behind him that he could feel growing closer and closer, stalking him, the prey in the water.
The first thing to give out was his left leg, pain radiating from his calf as the muscle cramped in protest. He felt himself begin to sink and the instinctive panic set in, as he thrashed, struggling to get to the surface. He should have known that he need not panic though, as strong tanned arms wrapped around him and began to swim upwards.
Astarion took in gulping breaths of air once he broke the surface of the water. “Astarion, you need not put yourself at harm's risk just to entertain me, my love,” Gale murmured softly, one arm shifting to wrap Astarion more securely against him, the other coming up to brush wet curls out of his face.
“I had to make it worth it for you, darling. This might be the last chance you get to chase me through the water like this for quite some time,” he teased, craning his head to look at his handsome lover. Gale's hair was tied back into a bun, the silver streaks running through it glistening from the sun's rays bouncing off of it, and Astarion's fingers itched to reach up and undo it. His eyes were crackling with purple lightning, a sign that he would be entering his mating period soon and the visual confirmation of what would ensue made Astarion's blood turn to molten lava in his veins. “After all, I won't be able to swim very fast when I'm weighed down by your pups.”
Despite having to twist a bit uncomfortably, he reached down past Gale's waist, searching for the slit in his shark half that he was intimately familiar with. A firm hand shot down to clamp around his wrist, stopping it in its tracks. Astarion was then spun around so that he was facing the merman. Any smart remarks he was about to make died when he saw Gale's expression, eyes almost completely black, flickering with purple, giving him a dangerous appearance that should have made Astarion want to turn and run, but instead, made him cling tighter to him.
“You like the idea of putting pups in me, darling?” He breathed out, wrapping his legs around Gale, angling his hips so that his still-clothed pussy pressed against his body. “Of filling my womb with your seed and making it take?”
“Watch your words, Astarion,” Gale growled out, his arm tightening around Astarion's midsection. His other hand came up to rest lightly on Astarion's throat, not hard enough to cut off air, no, but as a reminder that in the ocean, Gale was the predator. Under where Astarion was wrapped around him, he could feel Gale's penises begin to protrude from the slit. Shame, Astarion normally loved to finger and tongue at the slit until Gale was begging to fuck him. “You know not what you are asking.”
Didn't he? Astarion leaned in, pressing his forehead to Gale's, the smell of saltwater and ozone from Gale's magic permeating the air around them. “I'm asking you to give in and breed me, my love.”
With that, there was a final low growl and they were flying through the water at a dizzying speed. Astarion clung on tighter, trusting that Gale would keep him safe through the treacherous waters.
Then, they paused briefly, and Gale was muttering a spell, his magic settling over Astarion. “Hold on,” he commanded gruffly, and then they were diving.
The spell that Gale cast on Astarion allowed him to see clearly underwater, but this time, Gale swam at a more leisurely pace, occasionally pausing to press his lips to Astarion's to give him air. This exchange was more than familiar to Astarion and if he took advantage of it every so often by sliding a tongue into Gale's mouth, there was no one around to tell except a passing fish.
Astarion loved watching Gale swim through the water, his sleek grey tail cutting through the water in powerful strokes, the gills on the side of his neck flaring as he moved. He sometimes wondered what sort of tail he would gain, if he did ever decided to let Gale cast the ritual that would turn him.
In his musing, he realized that Gale must have taken the most direct route to his lair, as they broke through the surface into the cave they often stole away to for some privacy. At this point, Astarion could feel the magic rolling off of Gale as the primal instinct to mate, to breed, began to overtake him.
“Star, I can't–” Gale gasped out, sounding as if he was in pain.
Astarion reached up to pat his cheek, still secure in Gale's grasp. “Don't fight it. Make me yours. Give in.”
Gale’s eyes turned fully purple, as magic crackled around them and the next thing Astarion knew, he was restrained against a rock, his hands pinned by an invisible force above his head, something heavy around his waist. The hard impact made Astarion gasp, but that was turned into a moan as Gale’s body surrounded him, slamming his lips onto his, sharp nails trailing down his bare torso, leaving scratch marks in their wake that stung in the presence of the saltwater, but the pain only heightened Astarion’s excitement, the knowledge that his normally composed and gentle lover was reduced to this.
His swim gear was ripped off him, torn to shreds, but he was quickly distracted by his invisible bonds moving him up the rock, surprisingly gentle in their movement, offset by Gale roughly spreading his legs, throwing one of Astarion’s pale thighs over a tanned shoulder to expose what Astarion was sure was his profusely leaking cunt.
As if in slow motion, Astarion watched Gale lick his lips, gaze transfixed, before he leaned in. Astarion’s head thunked backwards as his eyes closed at the sensation of a wet tongue traced his hole, lapping up his slick, before slipping in and immediately curling upwards, pressing against Astarion’s wall. “Fuck!” Astarion yelled, his voice echoing through the cave, as Gale’s unnaturally long tongue hit his g-spot, heat spreading through his lower stomach.
“Gale!” He thrashed in his bonds, hips squirming, attempting to thrust further onto the tongue, needing to be filled more. His lover’s grip tightened on his thighs, pressing them flat on the rock, nails digging in the flesh. The tongue within Astarion pressed more firmly on the sensitive spot on his wall. Astarion felt his walls clench and he whined. His cunt pulsed and he grew even more wet, somehow.
Gale hummed, and there was a flash of irritation that cut through the arousal coursing through Astarion’s brain at how damn smug he managed to sound even with his mouth occupied. “You bastard,” he shot out, hoping to sound threatening, though the moan at the end of that insult made the effect fall short.
At that, Gale pulled back, his beard now glistening, looking up at Astarion with a raised eyebrow. “Weren’t you begging me to breed you not just a few moments ago, my love?” One of his hands slid towards Astarion’s cunt, thumb pressing against the erect clit. Astarion’s vision went white for a second. “If you’re to accept my eggs and cocks, you need to be prepared.” His tone was mild, in the same manner as when explaining how the magical world underwater worked, even as his thumb continued to circle the nub. Astarion was finding it difficult to formulate any sort of thought, his excitement rising at the thought of being filled so thoroughly.
“I’m ready,” Astarion growled out. “Can’t you feel how wet I am?”
Gale smiled, almost feral, as more invisible bonds came up to wrench Astarion’s legs further open. “Do you think you can take me, my love? In the way that I want to take you?” Carefully, avoiding nicking Astarion with his nails, Gale sunk three fingers into the trussed up elf.
Astarion screamed at the sudden stretch, echoed back to him off the cave walls, arching up as much as he could. There was no reprieve, no ‘gentle Gale’ murmuring praises into Astarion’s ear during love-making, but something darker, as Gale’s fingers immediately began to spread and move, stretching Astarion even further. His other hand was pressing down on Astarion’s stomach, pinning him while simultaneously thumbing at his clit.
“You’re so gorgeous, my star.” Gale was still talking, when he should have been pre-occupied with something else. “You’ll look beautiful carrying our children.”
Suddenly, the fingers within him disappeared, making him groan. The noise faded into a yelp as he was flipped over and moved so that he was now flush against Gale’s body. His ankles and wrists were still restrained, the bonds moving to keep his arms above his head and spreading his legs. Easy access, his brain supplied, making his face heat. There was persistent pressure along his ass and lower back, and he used the small amount of leverage he had to wiggle back against Gale’s cocks.
“Behave,” Gale hissed out, his voice a deep growl that drove Astarion insane.
“Or what?” he asked, turning his head to look at his lover, only for his head to be wrenched back, the rough grip on his chin sinking lower to settle at his throat.
“Or I’ll make you,” was the last thing Astarion heard before he was being filled by something thick, pressing into him slowly and deeply.
He moaned, his entire body shuddering, as his head met the solid muscle of Gale’s shoulder. The painful stretch stung a little, chased away by the pleasant feeling of Gale reaching deep within. Small noises were being punched out of him, as if the ability to talk had escaped him.
“You’re so tight around me, my star.” Gale’s breath was hot against his ear. His hips began to move, his cock sliding in and out of Astarion’s cunt. Whatever self-control the merman had shown the previous times they fucked was gone, his thrusts increasing in speed, hitting all of Astarion’s sweet spots with deadly accuracy. His other hand moved from his hip to wrap around him, pressing down on Astarion’s lower stomach, where he knew there would be the imprint of Gale’s cock pressing from inside him. “I want to see you wrecked, to see you gaping from taking both of my cocks in you.”
Gale must have been entering the height of his mating rut. That was the only explanation for the filthy words falling from his hips. Astarion whined, trying to angle his hips to somehow get Gale even deeper, even though he could feel the head of the dick pressing against the entrance to his womb.
“Look at you taking me, so good… so needy.” Gale pressed even harder on the bulge. “Already starting to take, isn’t it?” His hips stuttered a bit. “Fuck, Astarion… need to get both in you,” he groaned out.
“Do it,” Astarion gasped out, pushing his hips back. “Fuck a litter into me, Gale. Get me pregnant.”
Gale’s hand was removed from his neck, the other one still remaining in place to keep Astarion still in the water, as there was another cock pressing at his already-full hole. It was almost too much, as he continued to press, Astarion’s cunt snugly wrapped around the tip of one cock.
He didn’t complain though, only holding his breath and trying to force himself to relax as much as he could. He wanted this. Needed it.
Then, with a cry from Astarion and a low grunt from Gale, he was being filled even further, spread open. Gale’s magic instinctively spread his legs further to impale Astarion even deeper. He could feel everything from how wide his cunt was spread around Gale to the heads of the dual cocks poking at his cervix.
“Look at you,” Gale’s voice was low, hoarse with arousal. “I can feel me in you.” His hand was still on Astarion’s lower stomach. Astarion could feel the stretch of his skin there with two. He looked down and whimpered, seeing the evidence of how thoroughly Gale had claimed him. Then, the bump disappeared as Gale slid out, only to reappear once more as he slammed his cocks in.
Astarion felt himself grow wetter, his cunt pulsing around the cocks as he approached climax. “Gale,” he whimpered, tugging at his bonds. He needed something on his clit, desperately, in order to come.
Gale stilled, deep inside him. “Tell me what you need, Astarion,” he ordered, voice still low. “Tell me and it’s yours.”
Astarion let out a wail as his lover stopped his thrusts. He was so full and desperate. He couldn’t even clench around Gale for more friction, spread wide as he was. “Touch me, please,” he begged.
Immediately, he knew that Gale would be difficult about this as his other hand moved up his chest to tweak at a nipple, sending a shock through him. “You’ll have to be more specific, my love.” Gale said, pressing a kiss to Astarion’s shoulder.
“You bast– ah!” The insult was interrupted by another pinch to his nipple.
“Only good boys get bred, my dear.”
Astarion hated how unaffected Gale sounded, as he was losing his mind. “Fine, fuck me, breed me, just fucking touch my clit!” he snapped out impatiently.
Maybe he should have been more patient, as he was being both internally and externally stimulated in the next moment, fingers rubbing at his clit, as Gale’s thrusts grew in speed, battering at his cervix. It should have hurt. It did hurt, but was lost in the tidal wave of pleasure as Astarion tipped over the edge, feeling the growing pressure in his lower stomach increase.
His entire body trembled and shook, his moans growing louder with each stroke. After one particularly hard thrust, he was free-falling, vision going white.
There was a sharp pain on his shoulder as Gale bit down with sharp teeth, jolting him into another orgasm, making him shriek with oversensitivity. The grip Gale now had on his hips turned bruising as the merman’s thrusts began to increase in speed. “Fuck, Gale!” Astarion thrashed, still restrained by the invisible bonds, still coming. He was sure that if their lower halves hadn’t been underwater, he would be soaking everything with his own slick.
When he finally came to, he noticed that his entire body was now relaxed, but not in the normal post-orgasm way. It was like he had taken a muscle relaxant, only there was intense pressure within him. “I’m so close, my love,” Gale grunted out. He had stopped thrusting, and Astarion didn’t understand what was happening, until he felt it. Whatever was in Gale’s saliva must have relaxed his entire body, as the heads of the cock popped past the second barrier in his body and into his womb.
“Nngh, holy shit, holy shit,” was all he could get out as he watched the bulge in his stomach grow even more pronounced.
“Are you ready to take my eggs?” Now, Gale sounded affected, voice strained. “You’ll be so full here.” He stroked himself through Astarion’s skin. “You’ll look so beautiful round with our pups.” His thrusts were shallower now, as if unwilling to leave Astarion’s womb. It was no less overwhelming for Astarion.
“Fill me,” Astarion demanded.
Gale groaned, teeth clamping down once again on Astarion’s shoulder as his hips jerked forward.
Astarion could feel it- feel Gale’s cum pouring into him, stretching his womb in preparation for his eggs, getting ready to fertilize them, getting ready to make Astarion’s body the perfect place to grow and hatch into little merfolk. He watched in fascination as his stomach grew even more, a small preview of what was to come further in the pregnancy.
“Here they come, my love.” Despite how full he was, Astarion could feel the entrance to his cunt stretch even more, briefly, as something traveled up the larger of Gale’s cock, through his channel, making him gasp as it pressed against his g-spot, until it popped out, directly into his womb. “You’re so beautiful,” Gale murmured, still stroking at his stomach, growing as another three eggs were deposited. “Doing so well for me, my gorgeous good boy.”
Astarion squirmed, feeling another impending orgasm, somehow. “How many are there?” he asked, breathlessly.
“A dozen or so. Maybe more.”
It had only been six so far, and Astarion was already almost far too over sensitive. Another one. Astarion couldn’t help but jolt at this one, hissing a little.
He heard Gale groan and there were more invisible bonds tightening against him, one around his midsection, right under his nipples, and the other around his hips, under the growing bump, securing him more tightly against the merman.
Another two eggs and Astarion was coming once again, convulsing in Gale’s arms.
“Almost there, my love. Look at you.” Gale’s voice was reverent, as he hooked his chin around Astarion’s un-bitten shoulder to watch his stomach grow even more. Astarion already felt heavy, buoyed only with the support given to him. “Taking me and my young so well.”
“G-Gale,” Astarion felt wrung out, exhausted, at this point. His entire body felt like it had been electrified, with each press of a new egg within him sending weak sparks through him. “It’s so much.” But it wasn’t too much. It never would have been too much.
“They’ll be beautiful, my Star. You’ll see.”
Astarion didn’t doubt it. He hoped that their children would have Gale’s eyes.
His stomach grew even more with the last few eggs, but they weren’t finished, as Gale thrust once more. More come shot out from his other cock, distending his stomach even more and making Astarion moan out.
Only then, as Gale withdrew, was Astarion released. He began to sink, weighed down by the eggs and volume of cum within him, but found himself caught in Gale’s arms.
“You did so well,” Gale praised. He looked like he had come out of his primal rutting state. “How are you feeling?” he asked, scooping up Astarion in a bridal carry. Astarion could feel the come in him leaking out and he wanted to protest, but he wasn’t sure if there was any way to keep him plugged, as open as his cunt was.
“Good. Tired,” Astarion replied, wrapping an arm around Gale’s neck. They were suddenly on dry land, as Gale cast magic on himself that would give him human legs, still carrying Astarion.
Gale laughed. “I see I’ve fucked all the witty comebacks from you, my love,” he teased.
Astarion was lowered onto a bed, something that Gale had conjured when they first began their dalliance. “You’re overestimating yourself, darling.” Regardless, he sprawled out across the surface of the bed, rolling to his side as gravity made the weight of his bump uncomfortable. “Will I be able to walk on land once I let you change me?”
There was a pause that made Astarion worried for a moment, and he tilted his head to look up at Gale, who was standing there with his mouth open.
“Is everything alright?” Astarion asked. He knew he should move to get up, to check on his lover, but the effort to even sit up felt like too much.
“You would… let me perform the ritual?” Gale moved towards the bed hesitantly.
Astarion snorted. “Of course. Are you really expecting me to just leave you with our brood? They’ll be absolute nightmares,” he joked, in part to hide his own unease, in part to reassure Gale that he would not be alone in parenting. The thought that Gale would want to raise their children alone never crossed his mind until now.
“But they’ll be our nightmares,” Gale countered, then, in an action that shocked Astarion, he knelt down on one knee by his bed. “I can’t be sure that I’m doing this right, I’ve only observed other humans on the beach from a distance, but it would be an honor to have you by my side for the rest of our lives.”
It was sweet, Astarion supposed. Maybe it would have been a little sweeter had he not just been fucked and impregnated into oblivion, but he could forgive Gale for not understanding human traditions. “Of course it would be, darling. Come here and cuddle me.”
It wasn’t until Gale was securely behind him, that he allowed himself to say what was on his mind. “For what it’s worth, I want to stay by your side for the rest of my life, too.”
