The soft whistles from Angelfish had been following them for a while as they continued picking up rubbish on the beach. Dale, Quin and the new hires were out doing water testing and they had said they were going to stay back.

The grey blue oceanide wades in the water chirping and calling out to them as he flings rubbish on the sand for them to pick up. He circles around rocks but comes back to the shallow water barely skimming across the sand to be close.

They take the trash he throws, adding it to the bag even as he wobbles at them. "Angelfish no, not playing today, i'll go swimming in the reef later" they call back to him only paying mild attention. Their thoughts were off in the ocean, they hoped Big blue was alright he had been very scares since his ‘accident’ while Angelfish had become rather vocal and been pursuing them.

They yelp as he launches from the water to grab them pulling them into the shallow water with a loud thrill of triumph. "Angel Stop!" They yell struggling against his hold as he pulls them close. Their eyes look up to meet with the big pools of blue against black as he chirps and huffs out a little melody. “Ooeeeeneeooaee” comes from the Oceanide as he caws excitedly as his gambit succeeds.

But at their cry, he recoils in distress, fins drooping in dismay. "Ooeeaeeouueeaa!" he, chirruping anxiously it sounds almost pitiful as he hands cup their face. Another collection of whistles and whines leave him as he looks at them pleadingly

Feebly he trills another song, bumping his crest against their forehead. “Oeeaeeiaiaeeaeeeeeeoeeee." They squirm in his arms before finally settling when. "Angel please don't, I'm not one of your people, big blue understands and is staying away for a reason" they mumble.

"N..o o..o Bl..ue goo, I be wih ow." The words are crash, harsh even compared to his sweet little songs. But they understand enough of it to see what he's trying to state. He nuzzles their face pleadingly, eyes wide and bright.

" I fign.., fe..ed s..ae" he uses his clawed hands as he talks. “Angel Stop, you will hurt your throat” they try to plead for him to settle down. His fins flutters and flare as he gazes upon them. "B…e mm te?"

There is a long silence between them as they just stare at him in shock. "Angel... I can't, I'm not one of you, there are plenty of others of your kind" they explain only for him to pull them closer fins and frills flared in display head moving as if trying to showcase the colours that flare in the scales.

When they don't react to the little dance he huffs softly wet webbed hands cupping their face as he presses his lips to their in a messy and uncoordinated kiss. They gasp as he kisses them, it's out of the blue and such a human gesture, they lean into it softly, in truth it was a terrible kiss, he tasted of fish, seaweed and Salt. But his enthusiasm surprised them.

A pleading keen erupts from his vocals as he holds them close. "Aeeeeaeeuueeuueeeeaoaaooeeaouuaaeeouuooeeieeeeieeeeaaeeeeeeieeoaeeoaee." Angelfish trills eagerly at their softening, nuzzling into their hands with desperate affection. They look up to his eyes as his webbed hands cup their face tenderly. "I can get in trouble, the others I work with don't know you are this sentient, I will get in alot of trouble" they try to argue. But his soft little calls are making it hard to say no to him along with his big almost seal eyes.

He warbles in confusion, gathering their small form close in an embrace, "Oh angel..." they lean into his body resting their head against his shoulder as they hold him. The mer slowly drifts back while holding them. The afternoon light bounces off the waves of the surf as he just cradles them against his frame. He warbles softly, nuzzling their head with his own. Another little melody leaving him as they drift in the waves together.

"You want to sing for me?" They question. Not really understanding the meaning of his little songs but they sound much sweeter than him trying to mimic and use their words. Angelfish trills happily, brightening at their request. Carefully he carries them through the water.

They sit up on him watching how he navigates so swiftly on his back, the small saltwater and freshwater river were the last place they expected him to take them but in truth it was still beautiful. They watch as kingfishers and sea birds perch in the trees. Crabs scurry through sandy mud to find hiding places as the large predator leaserly swims with them sat atop of him.

It's a sheltered cove not the same as connected to the lagoons there's grassy little banks and it almost reminds them of fresh water swimming holes, with large rocks and little waterfalls that lead down into the mouth of the river where grass meets water. It's rather secluded despite how pretty it was.

Gently he settles them amidst the soft grass of the creek's lip, eyes bright and hopeful. His fins flutter showing off colours in display as a melody rises from his chest. Their eyes never leave him as he sings, a cascade of tones and harmonics flowing from his frame in waves.

It is so alike yet different from the songs of Whales and dolphins. As he spins around in the water, seeming to almost dance and he sings. Their legs rest in the water, his body brushing against them every twist and turn he makes in his dance. When its echoes fade, he nuzzles their face pressing himself close to them. the oceanide chitters and warbles happily at them. “ liked?”

His body slowly sinks down as he rests his head on their lap, nuzzling their legs nestled in the tide, fins fluttering softly as their hand comes to brush across them. " mate?" His eyes blaze with longing hope as he looks up at them.

They take a deep sigh before looking at him. "I don't know what to do even if I was too…" they mumble, trailing off. Were they really going to do this?. The oceanides are A completely different species, yes they could talk, and this one was rather eager for their permission. But this was still illegal, they were Sea life, animals. But as they look at Angelfish waiting patiently for their answer.

They were both consenting adults and he was the one trying to propersiton them, but the consequences of others finding out still weighed heavily. They snap out of their thoughts as clawed fingers to move to their clothing, Tugging and pulling trying to indicate what he wanted. He chirrups eagerly at them, his flared fins and frills shimmering as he still tries to impress them.

Fuck it.

Their hands move to the buttons of their shirt helping show him how to remove it. His eyes widen as webbed hands move across their exposed skin. They gasp as his cold webbed hands trace over their body. awe cross his face as he chirps at them. His claws trace aimless patterns, committing each new texture to memory.

A shaky croon erupts from his throat as he gently guilds their hands to his own body. The two tracing patterns and looking over each other's bodies as they try to figure out just how this was going to work.

Their eyes snapping down to him as he flicks his tongue out to run across their stomach before he dips down further. A loud gasp escapes them as he tilts their body back giving himself across to taste what he truly wants, a loud moan leaves them as he plunges his tongue deeper a loud rumble leaves him as he pulls them closer.

Their hands grip his head, guiding him and trying their hardest not to pull or damage his pretty frills. their hips rock into his mouth as he laps at them, hsi sharp teeth make them shutter as goosebumps flush across their skin.

The grey blue oceanide chirps eagerly at their sounds, Gently he urges closer, fins fluttering, and when they feel his teeth retract it leaves them stunned. ‘They have retractable teeth’ the muse over as he continued to drag his tongue over their sensitive skin. It makes them keen and arch into the touch.

Their back arches into the grass as Angelfish spreads their thighs wider, Gently he nuzzles his way back up their body. He gently pecks their face and neck, another small collection of thrills leaves him. Their gaze meets, as he rests himself above them. Claws digging into the grass as he looks down at them head tilted to the side.

They tense up and freeze slightly as he rolls his body against them, his clappers move against their own sex. But when they spread their head shoots down, chin rested on their chest as they watched his slit open. his penis emerges slowly, it's smooth a lighter blue than the rest of his grey blue body.

Their eyes widen as more of it slinks out of the slit. “Holy shit, holy shit” they gasp as the mer grinds against them. He chirps again softly checking over them again. “God I can't believe I'm doing this” they state In a hushed voice.

The Oceanide moves them around slightly, finding his preferred position, one webbed claw holds their hips as he moves closer, the head brushes against their entrance making them tense up. Angelfish coos at them softly as he presses against them again they tip slowly breaching.

They whimper loudly, as he presses deeper, it's a rather smooth glide due to the texture. It doesn't hurt nearly as much as they were expecting it too. A loud purr leaves Angelfish as he slowly rocks into them trills happily,

his back fins flutter wildly as he grinds himself deeper trying to press as far into them as he physically could. They clench at the feeling only to gasp and let their head fall back into the grass. They move slightly trying to find a more comfortable position, one leg hooking over his back.

Soft chitters of appreciation escape him, once happy Angelfish begins to rock back and forth, it's slow, sticky as he pulls his length out partially before slamming it back into them. Loud moans leave them as they grip onto him, fingers digging into his back as they cling onto him with each thrust.

Angelfish let out a loud whine, his body instinctively grinding back against theirs, his tail flicking each time he hilted in them, thrills of delight rattle down his spinal fins. Each thrust feels like they are gasping for air as he drives his spike deeper. The feeling of his scales are strange as he manoeuvres them but in truth they feel sinfully good against their skin.

"Ne…ed yo... waa,t..." his voice sounds so broken yet filled with desire and longing, his words broken as he tries to utter their words again. They dig their heel into the back of the grey blue mer. Eagerly clenching around him.

They cry out as Mers penis flares, a large knot locking them in place at the base as gush of seamen spilling into their smaller frame. Angelfish’s fins and frills extend in display as he thrills loudly, rutting quickly with each spurt that leaves his knotted length. It's uncomfortable after the first few spills, his load leaking out the sides of where they are joined.

They try moving around to become more comfortable but it only makes them whine at how full they are starting to feel. “Angel, fuck move please” they gasp out laying against the grass panting as they look up at Oceanide who seems rather content watching them.

His hands move over them as he checks them, pressing against their stomach only to make them wince. He cooed softly with worry written across his face. "I'm alright, fuck just wasn't expecting that " they whisper while rocking back against him.

He chirps softly as he pulls them closer. Leaning back splashing into the water with them pressed to his chest as he floats. It makes them yelp as they shoot him a dirty look. Pulling his fin which earns a hiss and a look like they had kicked a dog.

“don't do that” they grumble but settle against his body as he cradles them. as they gently drift in the water in lazy circles. Nuzzling their face with care, his thrills and calls mellow down into little chirps and rumbles. “God I'm so fucked if anyone finds out about this” they mumble to themself, eyes fluttering closed as they cuddle the large mer, it would be a problem for tomorrow, they were to drained and they doubt they would be getting away from the cling oceanide any time soon.

“what am I going to do with you Angel?” they mumble before sighing and letting the soft rumbles from his chest lure them into rest.

The soft whistles from Bluestreak had been following the human for a while as they continued picking strange objects off the beach. He wades in the water after them. Trying to get their attention by bringing similar looking stuff he found floating in the ocean. Bluestreak chirps brightly as he trails after the landwalker, fins flared and ablaze as he was hot on their trail. Every so often he surfaces alongside them, presenting another tidbit of flotsam meant to please.

But no amount of trinkets seem able to sway their focus from its task. Undaunted, the excitable mer redoubles his melody, “Soft one, please look at me, I'm trying, I want to prove my worth," He calls out hopeful they would spare him a glance.

He circles hopefully, water swirling around him as he tries to catch their attention.

Bluestreak caws excitedly as he succeeds in grabbing them and pulling them into the shallow water with him, making them forget their carrier of items and as their small hands briefly touch his frame he thrills in delight. But at their cry, he recoils in distress, fins drooping in dismay.

"No no, please don't push me away!" he pleads, chirruping anxiously. "I just want to know you, prove I can give and provide" eyes wide and shining. To have come so close only to fail - the thought is more than his youthful spark can bear. Feebly he trills bumping his crest against theirs. "One chance is all I ask, please let me prove myself."

Their words make him sag softly, feeling dejected at their tone and the words he could understand. "N..o o..o Bl..ue goo, I be wih ow." The words are crash, harsh on his throat as he tries to get across his point. He nuzzles their face pleadingly, eyes wide and bright.

"I want to protect, feed... Always keep you safe I will make a nest... Please, give a chance to provider and protector?" There is a long silence between them as they just stare at him.

When they don't react to the little dance he huffs softly wet webbed hands cupping their face as he presses his lips to their in a messy and uncoordinated kiss. He had seen humans do this before to relay affection and he hoped it would be enough for them to finally understand. eyes taste of strange flavours things he had very tried but he enjoyed it and if it meant they would accept him he would kiss them as many times as they wanted.

"B…e mm te?..." the landers words hurt to express but he wants the get better so they can understand, so he can talk with them. The sad tone in their voice again hurts to hear, they sound so dejected to him, the hadn't said no but they sounded as if they would be in trouble if they did say yes.

"M-mate, please...just try. Let me show you all the ways of the ocean. Our sparks are the same, even if we are shaped differently. Give me a chance," he almost begged eyes wide as he cups their face. nuzzling into their hands with desperate affection. Still his grasp of their strange world remains limited despite all longing.

"Trouble? For touching?" He warbles in confusion, optics rounding wide and bright. The thought of their tender moments sowing them hardship cuts like ice through his spark.

Determined, he gathers their small form close in an embrace.

they lean into his body resting their head against his shoulder as they hold him. Mumbling in their little crash words as he pulls them to slowly drift with him.

He doesn't understand. It's like how the elders told him to stay away from humans. We're they told to stay away from his people?

Bluestreak warbles softly, nuzzling their head with his own as he drifts further with them in his hold. Their gentle touch alone soothes some of his worries. "Nothing simple about you. Elders always said "stay away from you." He keens gently, hoping his melody conveys what words cannot.

The afternoon light bounces off the waves of the surf as he just cradles them against his frame. He warbles softly, nuzzling their head with his own. Another little melody leaving him as they drift in the waves together.

Their question is one he understands though. trilling happily, brightening at their request. Carefully he carries them through the water.

He glides thought the water on his back, making sure they stay sat atop of him. “this is my favourite place, i come here when i want to be away from the others” he coos.

Gently he settles them amidst the soft grass, eyes bright and hopeful.

His fins flutter showing off colours in display as a melody rises from his chest. The soft ones eyes never leave him as he sings, a cascade of tones and harmonics flowing from his frame in waves. He sings his spark out for them. As he spins around in the water, dancing and singing for them.

When he finishes his performance, he nuzzles their face pressing himself close to them. chitters and warbles happily at them. “ liked?”

" I sing and swim just for you!." Eagerly he nuzzles their legs nestled in the tide, fins fluttering softly as their hand comes to brush across his frills. " mate?" His eyes blaze with longing hope as he looks up at them.

His clawed fingers moved to their stange covering, Tugging and pulling trying to figure out how to get it off. “please i want to see you” He chirrups eagerly at them, his flared fins and frills shimmering as he still tries to impress them.

They moment they move to discard the covering he wants to sing loudly, to thrill in triumph. “ we take it slowly Watch and learn, then we mate." His fins flutters wildly as drawing them closer, claws trace aimless patterns across their soft skin, A shaky croon erupts from his throat in plea. "Touch me too, let me show you how? We mate, then swim and sing together." His mind is racing faster than he can talk.

The sweet scent from between their strange legs has his pupils dilating, his mouth is on them before he can even think, they smell so good, ready and in season, everything he could hope for. Their hands grip his head, earning a rumble from him.

their hips rock into his mouth as he laps at them eagerly drinking in the sweet taste of them, when he realises his teeth are brushing their soft skin he retracts them, he doesn't want to hurt his mate, no he didn't want them to bleed.

Their back arches into the grass as he spreads their thighs wider, Gently he nuzzles his way back up their body. He gently pecks their face and neck. They tense up and freeze slightly as he rolls his body against them, his clappers move against their own heat.

“shhh, I promise I'll take care of you” his slit open. Spike emerges slowly, Their eyes widen as more of it slinks out of the slit. they gasp as the mer grinds against them. “it won't hurt I promise” He chirps again softly checking over them again.

Once he finds his preferred position, one webbed claw holds their hips as he moves closer, the head of his spike brushes against their entrance making them tense up. “ no, no don't tense you will hurt yourself” he coos at them softly as he presses against them again the tip slowly breaching into their warmth.

It takes everything in him to not slam home into their tight little frame. They whimper loudly, as he presses deeper, they feel sinfully tight as he moves. A loud purr leaves him as he slowly rocks into them trills happily. “primus you feel amazing, mm my sweet little soft one” he whispers.

His back fins flutter wildly as he grinds himself deeper trying to press as far into them as he physically could. They clench at the feeling only to gasp and let their head fall back into the grass. They move slightly trying to find a more comfortable position, one leg hooking over his back.

"Ne…ed yo... waa,t..." his voice sounds so broken yet filled with desire and longing, his. They dig their heel into the his back. Eagerly clenching around him. Every thrust, every touch was a declaration of his primal need to breed and impregnate them, to claim them as his little mate. Would their pups take after his sweet little lander if they had them?

So many thoughts run through his mind as he holds them in place.

"Such a good mate... so eager for my pups" he coos to them, he knew they couldn't understand but at that moment he didn't care, they felt so good wrapped around his spike and he could feel his knot slowly inflating and locking them together.

They cry out as his Spike flares, a large knot locking them in place at the base as gush of his seed, spilling into their smaller frame. His fins and frills extend in display as he thrills loudly, rutting quickly with each spurt that leaves his knotted length.

He purrs deeply watching as he leaks from the confined space of his little lover, leaning down he presses his crest to their forehead in delight. When they begin to wiggle he pulls them to his chest. His hands move over them as he checks them, pressing against their stomach. “So full, you look lovely like this little mate"he hums in delight only to tense when they wince. He cooed softly with worry written across his face. they whisper while rocking back against him.

“Shhh, you did so well for me, so well, time for us to swim” he whispers to them as he flops back into the water with them cradled against his body. He chirps softly as he pulls them closer. Leaning back splashing into the water with them pressed to his chest as he floats. It makes them yelp as they shoot him a dirty look. Pulling his fin which earns a hiss and a look like they had kicked a dog. “What was that for?” He warbles at them worried he had offended or upset them. His hands are moving across their body again, checking them and praying that they were not hurt.

They grumble but settle against his body as he cradles them. as the two gently drift in the water in lazy circles. He nuzzles their face with care, slowly grooming their crest fluff. “ My pretty little mate” he chirps to them.
