A ship attacked in the night, sunk before anyone can hear the cries of its crew. A monster swimming around the wreck with a triumphant grin, circling the pieces falling onto the sea floor. He spares no glance to the sailors floating in their pitiful lifeboats, his appetite for destruction satiated. However, he notices the glint of gold in the waters, and he glides through the currents and fetches the body among the metal scraps. At first glance, it's a human, but he feels something else in their flesh. So he decides to take them with him, as a fine prize for his hunt. And as the creature slinks deeper in the ocean, the remnants of its attack floating silently on the surface of the sea.
The creature emerges in an underwater cave, a bubble of air deep beneath the surface. He slowly lowers the human on the dry rock, and waits. A few seconds later, the human coughs up water and starts heaving loudly as he fills his lungs with air again. He looks around, and immediately notices the giant creature watching him. Its head, the only thing that he can see right now, is as big as a house, and its deep blue eyes seem to be staring at his soul.
The man gasps, but the sharp breath irritates his throat even more and he coughs again. He crawls backwards, panicked, under the indifferent gaze of the creature.
"Who… where…?"
The creature sighs, rolling its eyes as a thick fog envelops it, filling the space until the man cannot see beyond his own feet. And just as fast, it vanishes, leaving in its stead a creature with the upper body of a man, and the lower half made of tentacles. It slowly crawls out of the waters, slithering on the rocky ground, not quite approaching the human but observing it cautiously. They stare at each other for a while, until eventually, the creature opens its mouth, revealing sharp teeth.
"Do you have a name, human?"
"What… Why do you care?" the man says, his voice tense.
"Curiosity. Not many humans wear the old sigils of the forgotten gods."
To add to his words, the monster points the man's arm with one of his tentacles. The human stumbles and tries to cover his skin, but the shirt, ripped by his fall among the ship's debris, barely covered anything anymore. He glares at the creature, than at the cave's entrance. Following his gaze, the monster chuckles with disdain.
"You can try to leave. I wonder which of the pressure or the lack of air will kill you first."
"Why did you bring me here?"
"Because I was bored, and you were cute."
That catches the man off guard. So when one of the tentacles wraps itself around his ankle, he doesn't react immediately. He is then unceremoniously dragged towards the creature, and lifted in the air until his face is in front of the monster's, hanging upside down by the leg.
"So? Your name?"
"Zhongli," he blurts out without thinking.
"I am Ajax. Remember to scream it later."
"What???"
Several slimy limbs slip under his clothes, rubbing his skin, the suckers feeling like a hundred mouths on his chest, back, shoulder, stomach. He's gently moved around, until his body is almost pressed again the monster's, leaving little to interpretation in that situation. Zhongli hisses, struggling against the tight hold the tentacles have on him, trying to escape the creature's grasp. But despite the slick covering the lower limbs, their grip is unyielding. The ones that aren't holding him in place are slithering under the fabric of his clothes, pinching and sucking at the skin, reducing the man to shivering, panting mess.
"Why… why are you…"
"Hmmm… You're sensitive, good."
Zhongli doesn't have time to think about those words, because he feels a tentacle wrapping around his half-hard cock, while another slip between his ass, rubbing a viscous slick on his nether region. He gasps, his hands clenching around nothing, as the tip of the appendage pushes past the tight entrance, the slimy fluid covering it making it easier. It presses inside slowly at first, then goes deeper once the muscles have stretched enough, and starts thrusting lazily.
"Wait, it's…"
"Relax, I won't hurt you. Unless you want me to."
Before Zhongli can reply, he's pulled closer to Ajax' face, salty and rough lips suddenly brushing against his, stealing a kiss with a satisfied snarl. The kiss is rough, filthy, too passionate for a monster and yet devoid of any affection. Ajax knows exactly what to do to rile up a human body, his hands holding Zhongli by the waist, keeping him close, his fingers pressing on the soft flesh, finding more and more sensitive spots all over his body. The tentacle inside his hole moves slowly, rubbing against the warm walls, relaxing the muscles gradually. Zhongli gasps when he feels another one probing at his entrance, wriggling its way inside, stretching the muscles even more. The man grabs Ajax's human arms for support, his back arching into the tentacles, pushing down on them unintentionally.
"Wait…! Wait, it's…"
Ajax smiles menacingly at him, leaning closer to Zhongli's lips, feeling the breath on his skin before he kisses him again. His hands, slightly colder and moist, wrap the man's waist, holding him in place while the tentacles begin moving faster. The monster sucks in the gasp escaping Zhongli's mouth, plunging his limbs until he can get the thickest parts in. After a moment, he pulls both out, tearing a broken sound from his partner. He breaks the kiss, licking Zhongli's lower lip with a grin.
"Now… the real fun starts…" he whispers with satisfaction.
Zhongli digs his nails in the monster's shoulders, bracing himself. He feels something poking at his hole, then pushing past the rim, stretching him even more than the previous tentacles. This one is a lot thicker, the suckers on the sides adding another layer of stimulation to the mess. The long and trembling whine leaving Zhongli's throat is so loud that it echoes in the cavern. Pleased with this reaction, Ajax uses his other arms to hold him in place, enjoying seeing his tentacle-cock thrusting in the tight hole, pushing deeper until he can see the bulge on the man's stomach. With his human hand, he presses softly against it, his thumb tracing over the small distention, watching it move as he thrusts his hectocotylus in the pliant body. His other hand grabs Zhongli's neck and pulls him in another kiss, muffling the gasps and moans coming from the man, more and more incoherent as he pounds into him with less and less restraint.
"You feel wonderful, I want to keep you with me now…"
Ajax whispers against Zhongli's lips, nipping at them teasingly. Zhongli whimpers and tries to turn his face away, but the monster doesn't let him. This time, a tongue pushes between his lips, forcing its way in his mouth and down his throat, the appendage abnormally long. It mimics the movement of the tentacle fucking him, overwhelming the poor unfortunate man's senses until he can't think anymore. He think he might have come, one, three? times, but he doesn't even know. His body feels like it's burning but the flames lick his skin like a caress, the tentacles soft and slimy holding him without hurting him. And even the pain of the thing inside of him has already been replaced by a twisted pleasure, leaving him boneless in the monster's embrace.
Ajax pulls him even closer, guiding his human legs to wrap around the place where his own human abdomen ends, the skin below his hip melding into the tentacles. He makes sure that Zhongli is firmly in his grasp before picking up the pace, holding him in his arms as he fucks the man on his cock. He notices with a proud smirk when Zhongli comes again, spilling his seed between their stomachs, his hole tightening around around the tentacle. He keeps thrusting, feeling his own climax near, knowing what will come after. He deepens the kiss as he buries his hectocotylus deep, filling the human's hole with his semen, so much that it starts dribbling out.
But not for long.
Zhongli dozes out for a moment, fucked out of his mind, Ajax' lips against his forcing him to breathe, the tongue retreating just enough to let air pass through. The warmth filling him up to the brim is uncomfortable but not painful, and he can feel his body relaxing with the exhaustion, like a puppet sudden stringless. That's the only reason he does not notice immediately when something pokes at his entrance. Or rather, when the tentacle starts swelling around something, and it presses again his rim for a moment before slipping inside of him, pressing against his sensitive walls. And then another, and another, until he can't ignore the feeling anymore.
"What is this…? What are you doing to me…?"
"Only filling you with empty eggs."
"E-Eggs????"
Ajax smirks, tightening his grip on Zhongli's body, watching his belly being filled with his seeds and his eggs… Too bad they won't give anything, but a kraken can dream, right? He pushes the last of the eggs out, and he breathes a sigh of relief. The pressure in his lower body finally eases, and he slowly lowers Zhongli onto the floor. He doesn't pull out yet, however, keeping all of his arms around Zhongli, relishing the warmth and softness of his human body. He blinks a few times before dozing off.
Zhongli is too tired for this, and the moment his head rest against Ajax' chest, he's gone, out for the world and whatever problems his future self will have to face.
At least that was the best sex of his life.
When the morning sadly comes, Zhongli wakes up to the most painful soreness he has ever felt in his life. He jolts awake with a groan, his mind not quite there yet. He's immediately greeted by the cold salty wind, the waves brushing against his legs, the fabric clinging to his skin…
Wait a minute.
He looks down at his legs, and yes, he's wearing his pants. And his shirt. He pats his body wherever he can reach, trying to piece his memories back together.
The wreck, falling into the sea, and… the… monster?
He tries to sit down, but it proves to be the worst mistake, for his buttocks made it clear that what happened hadn't been a dream. He looks down at his stomach, pat it cautiously, but the bulge is gone. He glances around, realising he is on a beach, and not in that cave anymore…
"Did he… bring me back?" he whispers to himself.
"I did, before sunrise, actually. You were sleeping so soundly, I couldn't wake you up at all."
A voice startles him, and he turns his head, his eyes immediately falling into these two abyssal irises.
"You… I thought…"
"That I would kidnap you to keep you in my dungeon so I could breed you and fill you with my hatchlings?"
"… Yes?"
The monster bursts out laughing, his human arms resting on a rock while the rest of his body soaked in the sea.
"I needed a body to release my eggs, I cannot do it on my own. Biology and hormones and all. Besides, keeping a human underwater would have been a nightmare," he adds with a playful grin. Then he lifts himself up, just enough to be at the same eye level as Zhongli. "But, seeing that you liked it that much, I figured I could… ask you to do it again?"
Zhongli blinks several times, his thoughts struggling to process the meaning of the words.
"Do you have to sink a boat every time?" he surprises himself asking.
Ajax snorts at his question and shakes his head.
"No unless I feel like it."
He leans closer to Zhongli, whispering in his ear.
"Come to shore at dusk. I will meet you there."
And before Zhongli can ask more, Ajax slips back into the water, disappearing into the depths. Seconds later, voices echo in the distance, calling Zhongli's name, and then people run to him, hugging him and talking to him.
But he keeps staring at the sea as if he wants to dive back in it.
