Part 2 for ‘Like Humans Do’

Pairing: Stucky

Description: Bucky is a merman, who is good friends with Steve, but sometimes he gets confused about human habits. Even if he stalks them a lot from the water.

Warning: Fluff, cute innocent Bucky, Smut (m/m), oral, fingering, beach sex, more innocent Bucky, and Steve really being in love with him

A/N: Okay, so the idea come from this post! Thank you very much for the author for this adorable drawing. I am a sucker for Merman AU Stucky from now.

It was two
weeks since Bucky first tried to kiss Steve, and it is safe to say, that it has
changed everything in their friendship. Now Steve visited Bucky every day
behind the rocks, where they have met before every time anyway. Now it wasn’t
rare, that the brunette took him swimming with himself, trying to show Steve
the most beautiful coral reefs he has discovered and chase the fishes
sometimes. Steve had the fin which he used to swim in the water when they got
far from the beach, but his legs were nowhere as muscular as Bucky’s fin, so
keeping up with him was rather difficult. It usually ended Bucky helping him,
teaching him the ways of his movements, or simply grabbing him, and pushing forward
in the water. Steve was good at diving and snorkelling and he could hold his
breath for a long time, which never failed to impress Bucky. Similarly, Steve
was impressed by Bucky’s physique, the way he was moving in the water and his
fin in itself looked like a miracle. It was longer than his legs would have
been, and his spine didn’t end above the curve of his ass. He didn’t have
knees, and well he could breathe under the water.

It didn’t
matter how it started, their daily meetups usually ended with heavy kissing and
a lot of unsatisfied desire. Sometimes they didn’t get out of the water, just
with their heads, and Bucky was holding both of them, as their lips met gently
or with fierce passion. Sometimes they got out of the water, laying on a beach
which was unreachable from the land. Hands roaming on each other’s body,
dipping into the wet locks, lips chasing each other. Steve always registered
how cold Bucky was, his lips, his fingers, his body in general, and Bucky was
always amazed by the warmth of Steve, and the softness of his skin, his hair.
It was unbelievable.

At the
moment when Steve’s hands went to Bucky’s fin he was clueless, just as Bucky
was with his thighs.

‘I can’t
really feel any touch here.’ Bucky mumbled resting his wet locks on Steve’s
chest. ‘The scales protect me and the only thing I can feel is pressure and
pain, warm or cold, but smooth touches like on my chest, no, I can’t.’ He explained
calmly, drawing patterns to Steve’s chest with his fingers.

‘It’s so
strange. I feel almost the same thing on my body everywhere.’ Steve said
calmly, his fingers massaging Bucky’s scalp.

‘I thought
it is different.’ The brunette turned slightly, leaning onto his elbows and
looked at Steve. ‘I used to watch people on the beach, and it always seem that
there are parts which are more sensitive. Also, already know that you neck is
more sensitive than some other parts, or the bone above your pants, your hips. You
love when I kiss you there.’

‘Yeah,
well, there are slight differences, but in general, we feel the same things.’

Bucky
didn’t answer just quietly thought about the couples on the beach, and what he has
learnt about human’s body and their reproduction.

‘You know,
those people on the beach, always get naked, lay on each other and it seems
they are enjoying this quite much. Would that be okay too? I mean, I can turn
tonight, if you want me to…’ His shyness and red cheeks were adorable according
to Steve, who felt he will never ever will get enough of Bucky.

‘Yes,
please. If you want to, I’d be happy if you’d turn, any you would be a human
for some days.’ Steve said calmly playing with the long locks. ‘And yes, we can
to that, if you want to. I mean I don’t know how much do you know about that,
but if you like kissing you will love that.’

‘I know
stuff.’ The merman grinned widely giving a peck to Steve. ‘However, I have
never done it, I couldn’t find a mate amongst the merfolks, and you are the
only human I have ever talked to. Remember, I count as a very young one as a
merman. We live longer and me being in my early twenties is like someone in their
late teens as a human. I only have had a few cycles so far and turned into a
human only twice. So, I have ideas about how your body looks like, and how it
works and the pleasure those people used to talk about, but I have never been with
anyone.’ Bucky confessed, making Steve smile gently and lift his head to reach the
pink lips for a meaningful kiss.

‘It’s okay.
We can go slow if you want…’

‘I don’t.’
He interrupted his friend. ‘We will have three or four days, so I really want
to use every second of it.’ Steve sometimes had no doubt about how young Bucky
could count as a merman. Sometimes he really sounded as a naughty teenager. ‘I
just need you to come to the beach at night and be with me.’

Steve had
to leave soon, but he promised Bucky that he will be there, in their secret
spot which wasn’t at the rocks, but at a calm little beach only they knew.

He was
there a few minutes before ten when the moon come up, making the water shine
with it’s silver colour, just as Bucky’s fin, Steve thought before he settled
on the sand. He didn’t have to wait for long until he could hear the typical
sound of the water when someone was moving in it. First it was smooth, than
with a painfully white flash under the water the sound become less even and
more loud. It took him a few seconds to got to see Bucky, who tried to swim
with his newly formed legs, but he failed pretty fast. He used his hands to
swim close to the beach and when his knee hit the sand he tried to stand up. It
ended in a huge splash.

‘Can I get
some help? I feel much heavier than I used to be!’ He asked Steve, who was in
the water in a second, pulling Bucky onto his feet, helping him to get out of
the water.

When they
walked out Steve let Bucky’s narrow hips go to pick something up from his backpack.

‘Steve!’ He
could hear Bucky’s desperate voice as he tried to balance on his two feet,
before ending up on his all fours. ‘Legs are confusing, and I am quite tall, so
could you please not letting me go?’ He sat onto his heels being a bit insecure
and looked up to Steve.

‘You are
beautiful.’ He breathed before he was kneeling in front of his lover, holding
his cheeks in his hands, pulling him into a deep kiss. When he opened his eyes,
they immediately went to Bucky’s newly formed legs. They were long and muscular
and as tanned as his torso. From his knees to his hips a dark blue short
covered them, which Bucky mentioned to buy earlier when he had turned for the
first time.

Steve
helped him up to his feet again, holding him securely, his eyes still on
Bucky’s legs.

‘Let’s get
back to the water, I can teach you how to walk there easier.’ He said and
started to walk until the water was surrounding them securely. ‘First try to
stand without my help.’ He said calmly as he let Bucky go, taking a step back.

‘It’s
easier here.’ The longhaired man laughed as he tried to balance.

‘Try to
walk here.’ He encouraged Bucky who started to walk and it seemed easier as the
water covered him until his shoulders. When he reached Steve, the blondie’s
arms held him close and he leaned in for a sweet kiss. ‘How does it feel?’ He
asked, his lips barely leaving Bucky’s.

‘This?
Good, very good!’ The brunette grinned and kissed Steve again. ‘The walking? It
is strange as always.’ Steve laughed and let him go again walking backwards to
the sand.

It went
like that until they got out of the water. Bucky reached Steve and his reward
was a kiss. A kiss which got more and more passionate by every stop. By the end
they were walking out of the water, lips locked to each other as their tongues
touched, swirling around each other. Steve reached behind himself when they
reached his back pack and he pulled out two towels and a blanket, still kissing
Bucky. He threw the blanket on the ground and the towels around their shoulders.
He grabbed the one on Bucky and slowly started to rub his wet skin with it,
which now seemed a lot warmer and softer. He earned a soft moan for his
ministrations as he quickly made the wetness disappear from Bucky’s skin.

‘Do you
want to go home?’ He asked enjoying as Bucky copied his movements and was
drying him with the towel. ‘Or do you want to stay here?’ He mumbled into the
eager lips.

‘I don’t
think I can go anywhere, Steve. I need you.’ He purred as his lips gazed over
the blond ones pulse point and tenderly kissed the sensitive skin on his neck.
A low moan erupted from Steve’s throat, and it just enhanced when he could feel
Bucky’s erection pressing to his thigh.

Bucky
quickly managed to lay him on his back on the blanket and kneeled above him,
forearms resting on both sides of Steve’s head as he tortured the sweet skin
with bites and sucks, leaving red marks in his trail. He hummed into the hot
skin when Steve’s hands started to roam on his body, touching his arms, back
and abs and mostly everything what Steve could reach. Bucky always felt amazing
under his hands but now, his skin was smoother and it only add up to Steves
desires.

The eager
bites and nibbling got to his chest than down to his stomach, making him moan
quietly. Bucky quickly undid his boardshort and stopped to look up to Steve.

‘Is this
okay?’ He asked shyly, however his swollen lips and blown pupils and his former
ministrations convinced Steve that Bucky wasn’t that innocent or shy at all. ‘I
have seen so many humans doing this, and I wanted to try it for so long…’ He
looked to the hazy blue eyes, as Steve nodded, dipping his fingers into the
wet, long locks.

Bucky
pulled down his board short, making him all exposed and naked, but he couldn’t
care less. All he needed was Bucky and his skilful lips on his body again, but
it never come.

‘Fuck,
Steve! You are gorgeous!’ Bucky whispered as he was staring at the beauty in
front of himself. ‘God, I imagined you so many times, but… Oh, god!’ He praised,
before leaning back to Steve’s shivering body and kissed along his hipbones, his
happy trail and then dipped his head between his legs. His sharp teeth worked
on the blond one’s thighs, making him tremble in anticipation and whimper
loudly. He was rock hard and leaking with precum, which Bucky licked from his
abdomen, and contently hummed for the taste. He carefully held Steve as his
base, and after a deep inhale he let his swollen tip into his mouth, making his
lover’s body shudder and his fingers grip the dark locks. It took only seconds
to Bucky to gain back his confidence and tease Steve in a way no one have ever
did before.

‘Bucky,
fuck!’ He cursed as he opened his eyes wide and arched his back under the
skilful lips. ‘Where did you learn this?’ He moaned, and Bucky would have smiled
if his mouth wouldn’t have been full with Steve.

‘I told you
I was stalking people and we were taught how to pleasure our mates at home.’ He
answered quickly before sucking Steve’s throbbing cock harshly, earning a
pleasurable cry. ‘It’s not entirely different.’ He added before letting the
long member into his throat and starting to bob his head up and down on the
leaking, long cock.

Steve was
speechless, however he already knew that Bucky was skilled with his mouth and
tongue, but this was something truly unexpected. The fact that his sweet lover
was technically purring to his taste and weighty dick in his mouth threw him
over the edge. ‘Bucky! Please, I’m gonna come!’ He pleaded and couldn’t help it
when the pleasure flooded his veins, consuming his body, making him tremble and
buck his hips into the sinful lips, which swallowed his hot, white cum as much
as they could. He was honestly amazed by Bucky’s skills, as he drunk his cum so
easily, barely a few drops were dripping down onto his chest as he sat up. His
red lips were glistering until Bucky used the back of his hand to make Steve’s
cum disappear from his mouth.

The
beautiful steel blue eyes looked to him with lust and painful need.

‘I want to
make you feel good, Buck!’ He mumbled and crashed his lips to Bucky’s turning
him onto his back, getting rid of the blue board short quickly. ‘Oh, god!’ He
moaned and leant back to Bucky’s lips. ‘You are fucking huge did you know
that?’ He asked voice low and husky. ‘You are so perfect, Buck!’ His fingers
pinched the sensitive nipples, making Bucky moan between his lips.

Steve
couldn’t really get enough of his body, now that he was allowed to touch him,
now that he knew how and where to touch him to make him cry out and feel good.
He made a quick work on the sensitive neck and the wide chest what he could see
ad touch many times before. His hands were roaming on the thick thighs, the
narrow hips and made him turn to his side, so he could grab the perfectly round
ass as he growled to the feeling. It went on like this, until Bucky was
trembling with need, the need of Steve touching him where he needed him the
most. Finally, the blond one had his mercy on him and turned him back to his
back and held his thick, heavy length in his hand.

‘Tell me,
if you want me to do anything differently!’ He whispered and gave Bucky a slow
stroke, earning a loud moan. He wanted to answer but he couldn’t because as
soon as Steve’s hot mouth touched his tip and his tongue swirled through it, he
forgot everything. Steve was the only thing what existed and the warm, gently
sucking feeling around his swollen length. He arched his back and bucked his
hips involuntarily as he sank deep into the hot throat around him.

He knew
they just started but he couldn’t hold it not a second longer. ‘Steve, I feel so
good, fuck. Stevie, I’ll come!’ He cried, and Steve started to suck him harder,
breaking the last piece of his consciousness and throwing himself over the
edge. His body shuddered as his orgasm washed over him, repeating Steve’s name
in the most sinful ways while he eagerly swallowed the hot seed spilling into
his mouth. When it was over Bucky was still shaking a bit, his eyes closed,
hands gripping the blond locks and his breathing was laboured, panting fast.

The blond
man laid next to him, gently kissing his temple, waiting until he come down
from his highs.

‘I’m sorry,
but it felt amazing!’ He breathed, opening his hazy eyes slowly.

‘I don’t
mind, we have three days to make you last longer.’ Steve laughed and placed a
gently kiss on the dry lips.

‘Steve, I
still need you.’ Bucky looked at him desperately. ‘I need you inside of me.
Please, I want to feel you!’ He begged quietly.

‘Tell me,
you didn’t saw from the humans too.’ A laugh erupted from Steve’s lungs and he
got up and got some lube from his bag.

‘Well, I
kind of saw them.’ He admitted. ‘But I know this anyway.’

‘God, you
shouldn’t watch people while they are doing it.’ Steve shook his head as he
returned to the blanket. ‘It is very inappropriate.’

‘I can’t
help it, I have a curious nature!’ Bucky defended himself biting his lips a
bit.

‘I can see
that.’ Steve was drawing slow circles on his abs and thighs. ‘You really want
it?’ He asked before leaning in for a kiss.

‘Yes!’
Bucky nod and Steve’s hand dipped between his thighs. 

‘Open your legs a bit
more!’

His hands
slipped to the tight entrance and started to circle around it. Bucky cursed and
tried to relax. He was nervous, but it felt so ridiculously good. The soft finger
circling around him, Steve’s lips on his, oh it was much more than he ever
dared to dream about. He could feel a little cold liquid dripping down to his
entrance as Steve added some lube, to make it more comfortable for him. He
sighed and whimpered in need when one digit penetrated his body, just for an
inch. It felt stretching but good at the same time. With the right amount of
lube Steve pushed his finger fully inside, moving it in and out slowly. When
Bucky’s body adjusted he gently joined a second finger, carefully monitoring
his lover’s reactions. His body stiffened for a second before it relaxed and he
could finger him easily. The third finger joined soon and by then Bucky was
whimpering in need and pleasure opening up his legs wide. Steve’s cock twitched
for the sight, already hard and pulsing with need.

‘It’s ok,
Steve. I can take you.’ The dark haired man whispered and opened his eyes, to
look at Steve, making him lose it endlessly. How could he resist, when Bucky was
asking him, when he was here, he turned to be human for him and he is laying
under him, asking for Steve to take him, to make him his. Oh, how could he say
no?

He coated
himself with lube, and pulled Bucky’s knees up a little so he chould reach him
more.

‘Tell me,
if I am hurting you!’ He mumbled and aligned himself to the hot entrance,
starting to push in slowly. It was entirely different than his fingers, it was
thicker and longer stretching him deliciously. The tanned skin was covered in cold sweat and it felt like
his blood would have been replaced by fire. Steve was burning and stretching
him from the inside, but his desires were driving him mad. Soon the blond man started
to move, and their moans and cries filled the hot, summer air quickly. When the
clear blue eyes got opened, he bit his lips to the sight. Bucky was laying
under him, legs spread open, lips parted, eyes closed, hair softly laying on
the blanket, as the full moon gave him a silver glow, making him even more
beautiful. His sinful moans made Steve go faster and deeper, until he hit his
sweet spot. Grinding to it with every thrust, making the pleasure grow in
Bucky’s body.

‘Steve, I
feel so good! God, please, right there! It’s so good!’ He cried before
unconsciously run his thumb over his leaking, sensitive tip. With one more deep
thrust his second orgasm washed over him, his walls clenching around Steve,
setting him off too. Bucky couldn’t see or hear anything, except their loud
moans and panting, as his back arched from the ground, and his cum painting his
abs and even his neck with white ribbons. He was milking Steve empty, feeling
he hot cum filling him, which prolonged his pleasure.

When they
both calmed down, and the only noise around them was the roar of the ocean, he
felt peace like never before. He was happy. Laying in Steve’s arms, trying to
process what they just did. It felt amazing.

‘Let’s get
to the water, get you cleaned up.’ Steve giggled as he looked at Bucky who was
covered with his glistering cum, and Steve’s was dripping down in his ass.

‘Yeah, good
idea.’ He agreed. In the water the kisses and the touches weren’t about passion or the primal
need than before. It was about love and caring and slowly exploring each
other’s body fully.

‘If you
want to, you can stay with me.’ Steve offered as he breathed a light kiss to
the soft lips. ‘I brought you clothes and shoes.’ He smiled into the soft lips. 

‘Steve…’ Bucky shook his head. ‘ You shouldn’t have to.’ He sighed as his hands went into the soft blond locks. ‘But I am happy to stay with you. I don’t want to miss any moment with you.’ He laughed before another gentle kiss.

‘I have so
many things to show to you.’ The blond one laughed interlocking his finger’s
with Bucky’s as they walked out of the water.

‘We can do anything as long as you are with me.’ Bucky whispered into the red lips as he finished with getting dressed. He got used to his legs and body quite fast this time. Steve smiled and started to walk towards his apartment while hissing a little at the itchy burning feeling on his left hip.

‘Something bit me…’ He huffed, scratching the burning area through his shirt.

‘I am not entirely sure about it.’ Bucky gripped tightly to the slender
fingers and smiled gently. ‘While you are showing me everything I think I’ll have to explain a couple of things… like the burn you feel in your hips.’
