Chapter Text
You don’t quite remember how it happened, as you laid atop this large males serpentine tail - it was cold to the touch, must be cold blooded - you thought to yourself, humming softly as hands explored over him. “You feel so soft..” Your tone was gentle, you were still surprised that a man so stern and stubborn, refusing any touch just…Allowed you atop his tail like this.
“Yeah well don’t push your luck, I told you just…make the pain go away..” he frowned, fins lowered almost to his cheeks, tone laced with sadness. Eyes following your hands as if he didn’t fully trust you yet, to which he obviously didn’t - this was pushing every red alarm within him, but he decided to try anyway.
“Lay down on your front for me Sebastian?” You hum gently, hands smoothing up his chest “You said your back hurt the worst, alongside your lower back to where that tail connects to your waist?” You hum, showing him you were listening to his troubles.
“Mhm…” Oh he was so very hesitant, you knew he was afraid - or rather uncomfortable with human touch, not wanting to degrade him with being some terrified victim, you knew he’d not like being seen as afraid, despite the fact you could tell. Mind rushing in every way you can help Sebastian feel as comfortable, safe and as calm as possible. “Like...This?” he broke the silence as he shuffled to roll over, you gently scooted so you straddled the back of his tail, his head glancing back at you shyly.
“That’s perfect sweetheart thank you..” you tested the waters with such a nickname, he gave nothing but a small flicker via his esca and a huff - unsure if that was discontent with such a name or simply him tolerating it, your brain seeming to refuse the fact he would've liked it. “Alright I’m going to touch over your lower back and upper once that’s done, that alright?” you only shuffled up closer to his waist before waiting for consent.
Sebastian greatly appreciated that, he gave a soft sigh - he knew he was safe “Y-Yeah...Thank you, go ahead..” he nodded, esca doing that same flicker, puzzle pieces slowly began putting themselves together, still you weren’t certain what it meant. You gave a soft smile and spoke more confidently this time.
“You’re doing so well for me, sweetheart” Your tone was silk like, smoothing out from your mouth as those hands did the same thing, gently caressing the pudgy muscles beneath them, rolling over the fat and denser flesh, low grunts and grumbles emitting from the large mer, “If anything hurts, tell me”
“No...Not hurting - can you go harder..?” He was significantly larger than you, it was obvious you’d need to knead harsher into his flesh to have it actually make a dent within those knots formed in his body. He gave a low grunt as you kneaded your palm into a tight knot you’d found in his lower back, you pushed downwards with your whole body weight, he let out a huff and sighed “GH-..hhff..” he appreciated the extra pressure, it felt good. “Better..” He reassured you.
“I’m glad, you’re just so bloody massive, I hope I can get rid of at least a couple of these aches for you, I can tell you’re stiff, got to loosen you up a bit.” You gave him a soft smile as you continued to be on the rougher side with your ministrations, tone positive as if to reinforce that he was safe under your touch. Hands expertly kneading into every hard lump of muscle and bundle of nerves you could find, “It’s a good thing I worked in massage therapy for a year or two huh?” A chuckle escaped you, opening up a little.
“No wonder it feels so good then..” Sebastian hummed, the reply just rolling off his tongue as he became more comfortable with conversing with you, you couldn’t help the growing smile on your face, giving him a gentle hum and nod - since he was resting his large head within two of his arms, his eyes just caught a glimpse of you, esca flicking slightly once more. He gave you a couple of clicks.
“What were those for?” You decide to pry, the clicks sounded quite nice, they reminded you of a dolphin or perhaps something different - not even you were sure of every DNA strand within this man but you knew that dolphin wasn’t part of his genetic makeup. “You’d think with being so marine...Like?” You frown, wondering if that even makes sense .
“Yeah?” Sebastian couldn’t help but smile and give a slight chuckle at your pause to think.
“You’d be more...Flexible?” You snorted at his chuckle, “Don’t, you’ll make me laugh”
“Doesn’t seem to take a lot huh?” He hummed and thought - “Well I am flexible, I’m just…” he was now the one thinking of the words “Pent and tense?”
“Tense makes sense, you’re all…stiff” You wonder and finally find the words you’re looking for, after just a moment anyway.
“-That’s the word! Stiff, I don’t...Know why I said pent, wrong word” He grumbled, not that ‘pent’ was far off a whole other issue he had. He cleared his throat and hummed “It feels better already anyway, thank you..”
“You’re welcome, though I’m not done yet, gonna do your upper back now, can I shuffle more upwards?” You ask and smooth your hands along his spine, earning a few more clicks and a grumble, he gives a soft ‘mhm’ and you slowly move your body to straddle his upper back now, your legs stretched to even be able to do such a thing. “Yikes, this is the worst amount of tension I’ve ever felt Sebastian…No wonder you’re hurting...Oh sweetheart” Your heart ached, knowing you were the first and likely only person he’d let do this, you intended to make it all go away.
Your hands were motivated, moving with intent and rubbing into every tense muscle you found, which was almost every single one. Minutes rolled by and turned into hours - you were exhausted and Sebastian had eventually fallen into a doze, you’d not noticed. “Phew..” you wipe some sweat after noticing it dripping from your forehead to the male's back “Sorry about-” You swallow your words feeling those soft sleepy breaths, so strong they basically lifted your body weight even while asleep. Carefully you slip down to the floor and look at his face “Bless..” you give a soft sigh and grab a water bottle by Sebastian’s storage room, taking a few gulps to cool the heat that rose through you. It certainly was on the stuffier side today.
You’d worked for maybe three hours just rubbing into his back, it must’ve felt heavenly - you watch as he eventually rolled over onto his back, giving a big stretch - still sleepy as those gorgeous blue eyes fluttered shut after being lidded for only a moment. “Mhn...” he gave a soft mumble as his tail twitched, now you got a good look at his tail, something - or rather something’s caught your attention.
“Oh…my god..” Your body moved on its own as you closed in on his tail - two thick appendages slowly emerged from what looked to be a cloaca, or a slit of sorts. “I shouldn’t be this close..” You begin to back away but you were in awe of the way they pulsated and grew, before they finally slapped softly against his abdomen. A hand catching you as you continued to back away.
“Or, you could get closer..” A gruff - sleepy voice broke the silence, and it had you shrieking, his fins lowering “Christ! Was that sound necessary?” he huffed, giving a low growl as he shook his head - two eyes shut from such a high pitched shrill.
“S-Sorry! Sorry!” You give a few deep breaths “You startled me! Fuckin’ hell Seb.” You frown “You’re...Wait- Why would you want me closer?” You cross your arms “I was lucky to even be allowed to massage your back, now suddenly you have your dick out!” You give an unappreciated huff “Communicate with me..” You sounded more sincere that time, the male's eyes opening a little wider, ears lowering, his head also coming to meet yours as he nuzzled your chin - it sounded ridiculous since he was so much bigger than you, but he was awfully cute..
“I’m sorry, you’re right. I’m comfortable with this…I dreamt of you..” he smiled and gave a low purr “Are...You comfortable with this?” he asked “That’s more important, I should’ve ask-”
“Yes, I am” You chuckle “Why wouldn’t I be? This is fulfilling like a bazillion fantasies of mine” You tease, eliciting his tongue slowly rolling from his snout in a snarky fashion, earning a giggle right back from you. “What…did you have in mind big boy?” A low hum sounding as you gave it genuine thought, he was so…Big. But you trusted him, so deeply.
“Can I make you feel good, like you did for me?” He asked softly, it was so genuine but so serious too, you could tell he really wanted this - to pleasure you. By the sounds of it he means just you. That had your whole body shivering, and you gave a soft nod. “No doll, I want words not body language, I need to hear you say it.”
“Yes Sebastian..” you give a little chuckle and sigh “Thank you, you’re amazing..” Communication was everything for this guy, that much you knew and it was truly adorable. “If I don’t like something I’ll be sure to let you know, though I highly doubt that’s even possible~” You cooed and gave him a cheeky smile, earning two clawed hands raking over your body and stripping you of your suit and remaining gear - you’d had most of it off since the massage after all.
Those hands didn’t move from your skin as he smoothed over every inch of your body, finally he lifted you from the floor with unsurprising ease, given his size of course. He sat up and coiled his tail up in a bundle, laying your shoulders and upper back against it as he held your hips so your legs were on each of his shoulders, every touch he gave you was gentle and calculated. Blood slowly began rushing to your head for a moment, but that feeling was quickly drowned out as his tongue curiously writhed from between his teeth and softly glided against your slit, “O-Oh..fuuuuck~” you couldn’t stop a smile from wobbling its way on your lips “S-Sebastian-!” the feeling was overwhelming as your hands went slack against his tail which supported your head more comfortably now, those cold blue eyes staring into yours as his maw opened wide, tongue leisurely circling your clit before gently plunging into your depths, the low dragged out moan you gave him had his cocks aching.
“God..” His tone was low as a growl rumbled from his chest, throat gurgling like that of a crocodile, it was oddly arousing. “You taste phenomenal.” he chuckled and let his hands dig into your hips and the way they dipped, it was addictive, as was the slick that slowly begun seeping from your cunt - Sebastian was more than happy to lap away and delve deeper into your velvety warmth “Mhnnff..” he moaned and used two fingers from a free arm to gently spread your lips, “Such a pretty colour~” he grinned and circled your slit, suckling on it so gently, that textured tongue would of been amazing to grind against.
Fuck it.
“Sebastian- fuck, please let me ride your face..” You were panting and moaning softly, each of your sides only making the large male more and more enthusiastic about continuing. However your request had him pausing, he gave a soft chuckle and blinked slowly at you - esca flickering again, he liked that. You finally figured out what those flickers meant. Eager hands helped you sit up, he laid back against his own tail now as you essentially swapped sides, your legs not needing to move much, your pussy now hovering over his mouth as you were pulled down by an eager man. “Ah!”
“Mhnff...Grhh...Hhnngmhn~” He was very vocal about his indulgence, lapping eagerly as his tongue eagerly pressed inside, but as you pulled your hips up, able to stand - feet on the floor. He let out a highly desperate whine, he wanted to be attached to your pussy at this rate “Wh-Why?” He moaned and panted against you, hot breaths almost sticking to your cunt.
“Not inside, I want to grind that tongue love~” you give a cheeky smile, wondering what the slight shuffling noise behind you was - you turn to see his tail wagging slightly. “Oh you are just too cute~” You give him a low chuckle “Good boy, tongue out. Show me how eager my pup is for me..” You watched his esca glow brighter, flicking slightly as he panted - tongue lolled from his mouth now as you slowly lowered your hips back down onto him. “Fuck yeah...It’s so textured, better than any grinder money can buy - that’s how perfect you are Sebastian~” You test out some praise, eyes glued to his cocks as you raised your hips one final time, turning so you were facing away from him now, laying against his chest “Move that slutty tongue.”
Another whine escaped Sebastian as he used his tongue to grind up and down against your folds and clit, using its girth and length to expertly stimulate every inch of your cunt, he was eager - being called a good boy, being told how good he was being. Alongside being your pet, it was all driving him insane. What he didn’t expect was the sudden foreign touch to his tail, very close to his slit.
“Easy baby, can I touch you?” You hum, still asking consent even this far in, you’d given it to him, you wanted it in return, “Keep lapping my cunt and give me a nice few sounds if it’s a yes pup, I don’t want words from you now, pets don’t use those~”
Oh fuck…
“Mhnn! Hnnnn!~” he gave a long keen, his tail wagging and cocks practically seeping pre, twitching - reaching for those exploring hands, he wanted you - no he needed you, your touch, everything. His sounds didn’t stop there, his hands didn’t either. He stroked over your body, easily reaching your tits as he placed his pointers against your nipples - rolling over the buds with gentle claws “Ghrhhhh..” he gave a growl as his eyes were glued to the cunt he was still tonguing.
“Good boy~” you purred “That’s what I like to hear doll face” a chuckle escaped you as you lowered your hands to stroke each length, seeing how eagerly he reacted had your own sex almost corresponding against the males tongue, that earned you quite the sound “You sound so fucking gorgeous back there Sebby, mhnn...Such a good b-boy- ah~” You let your own sounds escape you, giving him something to enjoy as you rubbed yourself against that tongue “fuck i’m close..” Sebastian’s cocks twitching within your hold from this information, how badly he wished he was inside you so he could feel you clench around him as you cum. But he’d have to wait for that.
“Mhnf~” he purred and eagerly began prodding at your hole with a hand that’d drifted from your tits, he was so large - he covered every inch of you. He wanted to speak but being told he couldn’t or rather shouldn’t only had it feeling that much more new and very exciting. “Mhnf…Ffhhhn~” He let you rub until your breaths became frequent pants, whines becoming higher in pitch as your orgasm hit you hard. He could feel every clench from your cunt against his tongue, the way your clit bounced so softly against him had Seb letting out a very long moan.
“God!~” You sighed, “you were amazing...C’mon big boy, put one in me already - you waited long enough..” You didn’t want to leave him hanging - however you were definitely caught off guard by just how eager he was, picking you up once more as he stood to his full height, your back placed against his chest as he looked down at you.
“Does your pup have permission to speak now hm?” he gave a low chuckle, seems he’d had enough, you respected it with a very eager nod. He lathered his hand as he stroked one of his members, lining the tip as his cock sunk into your pussy, the head was only slightly flared, it was textured just as his tongue was. Though you noticed how pretty they were, blue in colour, flaring outwards all the way down to the bulbous swells at the bases. “Like what you see?” he chuckled “They flare out when I’m aroused, and flatten when I’m not..” he gave you a small explanation, you watched his hand drift over his cock, the frills were very soft, his hands flattened them down with every up and downwards stroke - they were attentive as soon as the pressure left.
“God put it in me already baby..” You were the impatient one now, Sebastian enjoyed that. His teeth were showing off in a wide smile, he gave nothing but a low gurgled chuff - god every time he did those it had your body reacting with shivers. You glance down as you feel his tip prod towards your cunt “Mhn..” you hum softly and bite your lip as he breaches you, the flare around his tip pushing in and flaring outwards once inside, that same feeling repeating - each flare pushing outwards once inside until that bulbous swell was met with your slit “Fuuuck~” you felt winded, a clear bulge in your abdomen from the sheer volume of cock inside you.
“I can’t wait to watch you swell with my cum.” Sebastian gave you no warning before his clawed hands met the backs of your knees, holding your legs up high as he moved his hips down, each flare popping from your hole, before plunging back in, It was an absolutely delicious and addicting feeling, your eyes slightly rolling back as your pussy clenched around him with every deep inward thrust, that frilled tip kissing right against your cervix. “Fuck...You’re taking me perfectly baby..” he grunted, claws threatening to pierce your delicate flesh. “Mhnff..ghhrh..” He just let his sounds flow from his maw, drool pooling within his mouth as it slowly began to leak from the corners of his lips. “Ahhh~” Those thrusts were deep and calculated, he set a decent pace.
You knew he was just letting you get used to it, but you wanted to lose every thought within your mind “Fuck me until I go n-numb~” you barely managed to get those words out, he formed a wide grin, drool pouring from him now as he pressed you down into his tail, holding onto your hips as he practically bent you over his own tail and fucked into you bestially, his own tail slapping vigorously against your backside, the sounds that came from you were deafening “Ah! F-Fuck! Oh Sebast- Mhn! HaaAH! Nhhmhn! Ahhmm!” You felt like you were in heaven, his rutting was becoming haphazard, you knew he was close “Breed me, fill me with your fucking young Sebastian..” you panted, a hand desperately rubbing your clit in circles, your dirty talk only got you closer, Sebastian groaned and followed your lead.
“I’ll fucking fill you to the brim doll face, I’ll give you all my young, you want that, yeah?” He smirked and flipped you over, watching your hand return to your clit as he lined up his cock once more, pounding into you so rough he had to keep his hands above your shoulders to stop you from bouncing upwards so much. “Taking my cock so perfectly, like my own personal cock sleeve, my little sex toy. Made to hold all my cum, carry my children like a fucking i-incubator.” he snarled as his cocks ached for release - he waited for you.
“Oh f-fuck...Yes yes yes...ye-yes! Sebastian!” you screamed his name as those growing bundles of nerves finally popped, orgasm rushing in as your walls clenched the large males cock, Sebastian desperately fucked into you with vigour before his own orgasm overcame him, he pushed that bulbous swell through your slit, tip now pressed into your cervix. He let out a feral growl as he came, covering your chest as you watched those frills expand even larger, soon followed by the same feeling inside, “AHH!” your body shook as you struggled.
Sebastian pinned you down and lapped over your chest and neck, uncaring that he caught his own load on his tongue, he let our warning growls “let me fucking breed you. Whore.” he grinned darkly - hands pinning yours down against his own tail as he pumped his load straight into your womb, a wide smile plastered on your face as you felt numbed. “Thoroughly bred~” he huffed, his frilled cocks slowly calming - Sebastian slowly pulled his cock free of your sopping cunt, watching his load drip out from your hole. Your stomach slightly bulging from the sheer volume, if that was from one cock? You couldn’t wait to be filled by both.
You watch as his cocks slowly flattened and returned to his slit “That...W-was...Amazing..” you struggle to get your words out as he gently coils you, soft comforting purrs sounding from his throat, “You did amazing Sebastian...You losing yourself at the end there? Holy shit..”
“Was it too much? I didn’t hurt you did I?” He frowned a little and nuzzled your chin comfortingly, earning a giggle from you as it tickled, you shook your head “Words doll face..” he smiled and gave his own chuckle, how could he not? Hearing that giggle..
“Of course not..” you whisper and place a kiss to his snout “You did amazing, satisfied me better than anyone ever could, I fear you’re stuck with me from now on~” You teased
“Wrong, you’re the one stuck with me~” he swarmed you with his tail, giving you soft nibbles like that of a dog itching that one spot followed by plenty of loving kisses, the quiet echoes of chuckles and high pitched giggles echoed through the halls, it was all that could be heard before the silence returned, only to be broken by the sound of snores and soft sleepy breathing.
