****** A Not-So-Unpleasant Curse ******
by bleedingsalt
Summary
     During a hunt Sam gets hit with a curse by a nasty witch that won't
     disappear after he and Dean killed her. Now he's stuck in his 16-
     year-old body and he absolutely hates it. He has no idea how Lucifer
     will react to seeing him like this and he would prefer him not to,
     but how his other half reacts when he finds out what happened
     surprised Sam completely.
Notes
     We have way too little belly bulging kink fics for Samifer, so here
     you go!
“This isn’t funny, Dean! Stop laughing!” Sam was furious, but his brother just
wouldn’t stop. For the last hour, while they were on the road back to the
bunker, Dean had not stopped for even a minute and Sam was about to lose his
patience completely.
“You gotta admit, it’s hilarious, Sammy!” Dean had the time of his life, Sam
didn’t.
“You think it’s fun being stuck like this?” Sam asked and narrowed his eyes.
“Was it fun when you were fourteen again?”
“Hell no,” Dean grinned and winked at his little brother. “But this is my
revenge now, let me enjoy it for a while. You laughed your ass off when I
deaged too.”
“Not as obvious as you,” Sam huffed and crossed his arms. He leaned back in the
passenger's seat, shooting deadly glares at his reflection in the mirror and
window. He couldn’t believe this happened to him! How could he have been so
careless as to not notice what this witch was up to?
“Relax, Sammy,” Dean smiled and patted Sam’s head amused. “You’re smart, you’ll
find the revert spell soon.”
“Yeah and until then I’m stuck with this teenage body and have to listen to
your mocking. Awesome.” Sam rolled his eyes so hard his head began to hurt and
let out a frustrated sigh.
This was a disaster. Sure, he was stuck being sixteen and not fourteen, but it
was still embarrassing and annoying. He looked like a toddler in his way too
big clothes and his hair was so long it constantly fell into his eyes - not to
talk about the general problems a teenage body brought. The only thing he was
thankful for was that he never suffered from severe acne, other than that it
was not a pleasant experience.
“I bet your little boyfriend won’t be happy either.” Sam shot him a glare so
full of fury that Dean’s smug grin widened even more.
“Shut up or I’ll choke you,” Sam warned him. “My hands still work, you know.”
“Come on, learn to take a joke,” Dean chuckled and set the blinker to get off
the highway. “A grumpy sixteen year old won’t make any friends.”
“I hate you,” Sam sulked and switched his focus back on the road ahead of them.
Not that he actually did, but Dean could be an ass sometimes. Maybe he deserved
it, after all he did laugh when he was suddenly faced with the fourteen year
old version of his brother. Still, it was annoying and Dean never knew when to
stop a joke. Damn, he hated being so… tiny. This wasn’t the body he was used to
anymore. There were barely any muscles, he was shorter than Dean and even his
face looked like a stranger… this innocent face didn’t fit him at all. He could
only hope that he’d find the reverse spell for this soon - if he’d be stuck
like this for longer he would go insane.
After a long and very uncomfortable drive - luckily rarely interrupted by a
dumb joke Dean couldn’t hold back after Sam’s scolding - the brothers finally
arrived at the bunker. It was way past midnight already, but even though Sam
was dying to get inside and hide in his bed, he hesitated. Dean leaned against
his door and grinned at him, to which Sam was forced to get out of the car.
“Nervous?” Dean asked, ruffling Sam’s hair playfully. Sam huffed and stepped
away a bit, trying to fix the mess his brother had created.
“I’m not nervous,” he insisted, even if it was obvious that he was. “I just
hate looking like this.”
“It could be worse, you know,” Dean shrugged and shouldered his duffle bag
before handing Sam his own. “You could have turned eighty, that would be a
turnoff for sure.”
Sam was about to come back with a sassy remark, but Dean already walked inside
and all he could do was clench one of his hands to a fist, cursing himself
internally. He stood in the garage for a few more minutes, trying to figure out
how to hide the fact that he turned back into his sixteen year old self, but
there’s really no way to do that. He’d have to go inside, unless he planned to
sleep in the garage. It wasn’t the worst place to sleep, but he needed his own
damn bed now, badly.
So, eventually, Sam summoned all his courage, shouldered his duffle bag and
stepped inside. He made the way to his room uninterrupted, almost believing he
would make it without being noticed, but as soon as his hand touched the knob
on his door he was stopped cold.
“Sam?”
The hunter took a deep breath before clearing his throat, trying his best to
mimic his normal voice.
“Yeah, we’re back,” he said slowly, gripping the doorknob tight. “But I’m
really tired, I just wanna get to bed honestly.”
Despite his naive hope that this would be enough to be left alone, he should
have known it wasn’t that easy. After a hunt, especially one that kept him away
for a few days, he never just got to go to bed right away.
“Are you okay?”
The corridor was dark, luckily, but Sam knew that his voice had given him away.
He sighed and let his hand drop.
“Yeah… no. I don’t know, really. I’d rather not have you see me right now…”
He knew that this wasn’t how he ever acted, usually he would welcome the
company and affection that followed hunts like this, but he was scared of the
reaction this time.
“Did anything happen? Did I do something?” Heavy steps followed the words and
Sam braced himself for what would follow. Not even a minute later, strong arms
were wrapped around him - much stronger than usual because he was much more
fragile - and he felt the body that was pressed against him stiffen. “Sam… what
happened?”
“Don’t be mad, please,” Sam mumbled and grabbed the hands covering his chest.
“I didn’t pay attention and… the witch got me a bit. It’s nothing bad, I’ll
find a way to fix it, but right now… I think it’s better if I am alone for a
while.”
“Whatever it is, I won’t let you deal with this alone, Sam.” A kiss on his head
followed, which made Sam smile unwillingly. “Don’t be afraid to let me help
you, I’m always here for you, no matter what it is. I thought you knew that.”
“I know,” Sam sighed. He couldn’t do this, no way. They promised each other to
be there at all times, he couldn’t ditch this now. “Alright, come in then.”
Carefully, Sam opened the door to his room and stepped in, a bit sad that the
arms around him let go. Once the door was closed, however, and the lights were
turned on, his nervousness came back even worse than before. He hadn’t turned
around yet, he was facing his bed and stood in a way that partially masked his
condition, but he knew he had to spill the truth now.
“You worry me, Sam. Please talk to me.”
“I’m sorry,” Sam said and shook his head slowly. “I didn’t mean to worry you,
it’s really nothing bad. I just…” he grabbed the hood of his sweater and pulled
it back, revealing the unusually short hair he had hid underneath. “I think I
lost a few years…”
A few moments of silence passed, then two strong hands grabbed Sam by the
shoulders and slowly turned him around. It was the hardest thing he ever did,
but Sam forced himself to look up and meet the eyes of his other half.
“I’m sorry, I know this isn’t the me you know,” he mumbled.
“Sam,” Lucifer smiled, his hands cupping the brunet's face and thumbs brushing
over his cheeks. “Why would you ever think you have to hide from me?”
“I don’t know,” Sam said and looked away. “I’m sixteen again… this… this isn’t
me. I mean, I’m still me inside, but this body… it’s not mine anymore. It feels
so weird looking like this…”
“And you think I would adore you any less like this?” The blond leaned down -
for the first time in their relationship - and pressed a kiss on Sam’s
forehead. “You are still my other half, I still love you no matter how you
look.”
“But I’m so… weak,” Sam said, almost disgusted by the thought of how he looked.
“I lost almost twenty years, how could you not feel that this is strange and
weird?”
“Sam, Sam, Sam,” Lucifer chuckled quietly. “Sixteen, Thirty-four or Fifty-five
- it doesn’t matter to me. Nothing matters but who you are and that’s not your
body. You are mine, I am yours, nothing will ever change that.”
“Lucifer…” Sam was out of words. He expected him to be appalled or at least
confused, but Lucifer showed none of that. All Sam could see in his deep blue
eyes was the same devotion he knew. He didn’t know what to say.
“I know you think I am thrown off by your appearance, but I could never be,”
Lucifer assured him, caressing his cheeks again. “As long as you are here and
well, everything is perfect. And I know you are physically fine, even if you
think you're wrong right now. I can feel it.”
Sam smiled at Lucifer, leaning into the gentle touch on his face. He should
have known better than to doubt him, he knew that, and he felt bad for not
following his instincts. Lucifer smiled back, brushing one of Sam’s locks out
of his face. His hands were still as tender and loving as always, just as
everything else about his behavior.
“I will find a way to fix this, I promise,” Sam said because he couldn’t think
of anything else to say right now. “I’ll be back to the Sam you know soon.”
“I love every you, Sam,” Lucifer promised and, with the most sincerity Sam
could imagine, placed a gentle kiss on the hunter’s lips. Sam immediately
melted against him, steadied by the angel’s embrace and giving into the
wonderful touch he loved so much. “And since I’m honest with you, I have to say
that you look absolutely stunning and gorgeous like this.”
“W-what?” Sam blinked confused, not quite sure if he understood that right.
“You look like a beautiful innocent boy, far from any form of corruption,”
Lucifer said with a smile on his lips. “I know that this is just your outside,
but you should see yourself the way I do. You look like a sin walking on two
legs, despite your sweet and innocent face suggesting otherwise.”
Sam didn’t know if he had ever blushed so hard before, but now he definitely
was. Something about the way Lucifer spoke made his loins sting, even more so
when the angel let his fingertips brush over his cheek and jawline.
“I know you are not innocent at all,” Lucifer continued sheepishly. “But you
looking like you do is more than just a little tempting.”
“Tempting for what?” Sam breathed when Lucifer suddenly pressed a kiss on his
jaw and let another follow on his neck.
“To show you that this has some perks too,” Lucifer smiled against his skin
before another kiss. “Because, even if you think it’s weird, I love seeing you
all innocent and pure like this… you are still absolutely gorgeous and I would
love to prove it to you.”
“Luci…”
Sam had no time to talk, because his lips were sealed with Lucifer’s right away
and he closed his eyes at the welcomed and amazing feeling. Lucifer’s arm
wrapped around his unusually small waist and he let himself relax into the
embrace willingly. It felt incredible that Lucifer didn’t hesitate for even a
moment to accept Sam the way he was - the complete opposite of what he had
expected to happen. He wrapped his arms around Lucifer’s neck, smiling into
their kiss when he realized just how much the roles had changed.
“My lovely Sammy,” Lucifer purred in such a sweet and soft tone that Sam felt a
shiver run down his spine. “You are perfect to me, no matter how you look.
Don’t think about it, please…”
“I won’t,” Sam whispered.
He was completely incapable of resisting Lucifer’s touches and kisses - it had
always been this way but today something made him especially vulnerable for his
angel’s affections.
“You’re still mine, Sam,” Lucifer cooed and brushed a hand through his
unusually long hair. “You’ll always be mine, no matter what happens.”
Sam let out a sigh of relief and didn’t protest at all when Lucifer suddenly
lifted him up with way too much ease. Of course he wanted to protest - this
really wasn’t how things were going usually and it felt kind of awkward - but
there was not a single bit of doubt in Lucifer’s actions, so he let it happen
and tried to not think about it too much.
When Lucifer let Sam down on his bed, the hunter was incredibly nervous though.
He anticipated what would surely happen, but at the same time he didn’t know if
he could satisfy Lucifer, which showed clearly when he looked up at the angel.
Lucifer immediately picked up on Sam’s insecurity and gave him the warmest and
most loving smile.
“You have always been absolutely perfect, Sam,” he said, running a hand over
the brunet’s neck and chest gently. Sam tried to relax when Lucifer’s hands
brushed over his crotch and then rested right on the growing bulge in his
pants. It was impossible to hide his excitement completely - as if his body
worked against him any way it could.
“Be careful, okay?” Sam whispered, a shy and slightly embarrassed smile on his
lips. “I’ve never done this while looking like I do now…”
“I’ll make sure you will enjoy it,” Lucifer promised, teasingly pressing
against Sam’s crotch. “I won’t break you, promised.”
Sam smiled innocently, but Lucifer had addressed one of his biggest fears.
Right now he was younger, yes, but also much more fragile, even if he didn’t
like it. Lucifer was an angel after all, with a strength that could never
compare to his. Normally is was clear how far Lucifer could go, but right now
everything was mixed up and that scared Sam a little.
When the angel carefully peeled Sam out of his way too big clothes, he was
actually kind of relieved. They made him feel even smaller than he already was
and that didn’t help at all. After those clothes were finally gone and Sam
watched Lucifer’s eyes roam his body, he felt a bit awkward though.
“I’m… not as muscular, I know…” Sam mumbled blushing and trying to evade
Lucifer’s gaze.
“Oh, don’t worry,” Lucifer chuckled, his hands roaming Sam’s chest and sides
again already and an excited tone in his voice. His hand wandered down Sam’s
stomach again, groping him between his legs and making him arch his back under
the demanding and arousing touch. “Yeah, that’s how you like it, don’t you?”
Sam wasn’t sure if this was his bod responding or not, but the effect Lucifer
had with just this simple touch was incredible. The more Lucifer pressed and
rubbed against the bulge in his pants, the more Sam’s stomach and loins
screamed and felt hot. It was worse than what he usually experienced, but
intense enough to make him not care why he suddenly felt this way. When
Lucifer’s hand shoved into his pants he bucked his hips against him, a quiet
sound of arousal leaving his lips.
“You still like that, don’t you?” Lucifer murmured, grabbing Sam’s cock with
his strong hand and making him tremble from head to toes.
“Fuck… yes!” Sam couldn’t hold his excitement, as much as it embarrassed him.
Lucifer smirked, his hand working wonders on Sam’s manhood - if he could even
call it that - while simultaneously letting his lips brush over his stomach and
placing kisses on it from time to time. Sam could feel his lips pursing against
his skin and it sent all kinds of shivers through his body.
“So much youthful eager,” Lucifer chuckled and pushed himself up with one hand,
searching for Sam’s eyes. “Just relax and let me make you feel good tonight.”
Sam’s head began to spin when Lucifer drowned him in another deep kiss and
pressed him into the mattress. Before he was touched like that, Sam had had no
idea just how desperately he needed this, but now that they started he knew
that he didn’t want it to stop anymore. Despite everything feeling different
than usual - from Lucifer lips against his own and his tongue invading his
mouth, to the way his hands felt on his skin - Sam craved this exciting new
sensations he experienced.
Lucifer barely let Sam enough time to breathe after breaking their kiss,
continuing to explore Sam’s newly slender body with his lips in every way he
knew. Kisses and playful bites on his neck that made Sam gasp from surprise and
excitement, followed by a trail of kisses that ended with him moaning out loud
when Lucifer took one of his nipples between his teeth and circled it with his
tongue. Sam’s knuckles turned white from grabbing the sheets beneath him so
hard in a desperate attempt to find something to hold onto. All the while,
Lucifer’s hand stroke and pinched his hard cock, coaxing more groans from the
hunter.
“You sure love this, don’t you?” Lucifer chuckled and finally let go of Sam’s
slightly swollen nipples to look back into his eyes. “Wanna feel even better?”
“Oh god, yes please!” Sam wanted it so badly, he could barely hold it together
anymore. With a few quick and experienced moves, Lucifer stripped off his own
clothes and even though Sam knew what he would have to expect, he was still
shocked by the sight. He swallowed hard, fear returning to his hazel eyes when
he looked up.”
“Afraid?” Lucifer asked, pecking Sam’s lips gently and smiling.
“Will it… will it work?” Sam asked, not knowing how else to word his worries.
It was probably due to his new perspective, but Lucifer never looked so big to
him before and it was rather intimidating. “I mean, do you think you’ll… fit?”
“Oh Sammy,” Lucifer laughed and caressed his cheek tenderly. “Everything’s
gonna be alright, I promise. I’ll be gentle.”
Sam nodded, knowing that Lucifer would never lie to him, especially not about
this. He took a deep breath and closed his eyes when the blond’s hand moved
further down from his crotch and pressed a finger between his cheeks. Somehow
it was one reason to believe Lucifer and another to act like it.
“Sam, look at me,” Lucifer murmured and, without being able to resist, Sam
opened his eyes again and looked into his. “We were made for each other,
remember?” Lucifer smiled warmly. “It will work, I promise. Just relax for me.”
“Okay,” Sam smiled back, still a bit frightened, but kind of relieved too.
Lucifer was right, he just had to relax and it would be all good. No need to
worry.
After a few seconds, Lucifer continued moving his hand and Sam tried his best
not to tense up. It was different, yes, but not at all unpleasant. Lucifer was
gentle, as he had promised and when he eventually pushed one of his fingers
inside there was no pain at all. Still, Sam’s hips bucked and he soaked in air.
“That’s my boy,” Lucifer whispered against Sam’s skin before placing another
soft kiss on his stomach as he pushed his finger deeper. He waited a few
seconds like this, allowing Sam to adjust to this new feeling, before starting
to slowly move a little. Apparently he knew how scared Sam actually was and
didn’t want to take any risks. Sam was glad about that.
Sam barely realized when Lucifer added another finger, only when he suddenly
moved both he did and threw his head back in pleasure. He couldn’t hold in a
moan, which encouraged Lucifer to continue and turn the usually so fierce
hunter into a shaky mess under his touch. Not that Sam minded, but he had never
before felt this kind of intensity before and it was impossible to control
himself at all anymore.
“You think you’re ready, big boy?” Lucifer asked suddenly, pulling Sam’s
attention back at him. The hunter looked up with glossy eyes, nodding slowly.
“Just do it slowly,” he asked with an already hoarse voice.
“Anything you want,” Lucifer promised and pulled his fingers out in a teasingly
slow way that made Sam beg for more internally.
It was almost torture to wait for Lucifer to continue, even if it was at most
five seconds. Sam was so needy now that he could barely hold back from begging
out loud. When Lucifer finally pressed his cock against Sam’s entrance, the was
unable to stop a hiss. Only now, when Lucifer began pushing in, there was pain,
but it was overshadowed by the incredible pleasure and heat overwhelming him.
Sam fell into a long and utterly lustful moan until Lucifer eventually stopped
moving and he looked up confused.
“What’s wrong?” he gasped, barely able to form the words properly.
“Just enjoying the gorgeous sight,” Lucifer smiled and trailed his fingers over
Sam’s chest. “You feel so good Sam, so incredibly good.”
When Lucifer pushed in deeper, Sam’s hands grabbed the angel’s legs and he dug
his nails into Lucifer’s skin while moaning deeply. It felt like an eternity
until Lucifer was filling him up completely, but Sam couldn’t complain at all.
His eyes rolled back at the pleasure he felt and he barely noticed it when
Lucifer spoke again.
“Holy hell…” Lucifer hissed. Sam’s head rolled to the side, a silly smile on
his face.
“Huh?” Was all Sam could produce. He was so far gone that only a gentle touch
on his face could bring him back to reality. Hooded eyes looked up at Lucifer,
hoping to catch his eyes, but they were completely mesmerized and somewhere
else.
“Sam…” Lucifer breathed and now, finally, the hunter’s attention was back. He
followed Lucifer’s gaze and his eyes grew wide at what he saw.
“Oh my god…”
His new body brought more than the obvious changes for Sam as it seemed and
this was something he would have never expected. His stomach, usually flat and
in his normal body muscular and firm, now showed an obvious bulge in the
middle. Sam soaked in air and held his breath, which made the bulge just more
obvious. This new sight made Sam’s heart beat twice as fast as normal and he
looked at Lucifer for answers, only to be met with the same fascinated glare.
Suddenly, Lucifer began moving and Sam’s gaze immediately shifted back to his
stomach, unable to believe what he saw. Every time Lucifer thrusted into him
ever so slightly, the bulge moved with him, revealing the truth about what it
was. Sam barely had time to think about it though because this new intense
feeling was taking over him completely.
“Oh my god…” Sam moaned again, answered by Lucifer grunting in a way he had
never heard before.
“Give me your hand,” Lucifer gasped, not stopping in his motions, and grabbed
for one of Sam’s arms without waiting for an answer. When he pressed the
hunter’s hand on his own stomach, right against the moving bulge, Sam thought
he was going to pass out.
“Can you feel it?” Lucifer asked, but Sam couldn’t answer.
Feeling Lucifer so deep inside him was one thing that was already overwhelming,
but now he also felt him against his own hand, with nothing more than his skin
separating his hand from him, and it was too much to comprehend. All Sam could
do was moan and press his eyes shut at just how incredible this new feeling
was.
“Fuck, Sam…”
Sam could feel that Lucifer wasn’t going to hold onto himself any longer, but
if he was honest he didn’t want him to. This was so incredible and intense, he
wanted more of it no matter the consequences. When Lucifer eventually began
thrusting into him deeper, Sam encouraged him by pressing against him and
pressing his hand on his stomach even harder. He didn’t expect his new age-loss
causing something so damn amazing but he wanted it to last for as long as
possible. Lucifer’s free hand pressed against Sam’s chest, holding him down,
and the pressure his fingers dug against his skin with would surely leave
markings for days.
Even after their countless nights filled with sex, Sam didn’t think Lucifer had
ever fucked him so relentlessly and deep before. He was pressed into the
mattress with enough force to prevent any movements, Lucifer’s thrusts
mercilessly splitting him open and making him cry out from pleasure within a
matter of seconds and feeling everything twice as intense thanks to the fact
that Lucifer was so rough. When Sam came for the first time Lucifer had barely
started actually fucking him, but this orgasm was soon followed by another and
Sam couldn’t bother to keep track after that anymore.
Sam knew he would be sore the next day, but he couldn’t have cared less if the
price was this unbelievable lust taking over him. For the first time Sam
actually lost count at how often he cried out Lucifer’s name. There was just
Lucifer filling him up so perfectly, his cock penetrating his prostate and
probably a lot more given the bulge on his stomach, and their moans filling the
heated air around them.
When Lucifer finally came inside him, Sam was overwhelmed by a last and
probably the most incredible orgasm he had ever experienced. He actually cried
at this point, tears of joy and pleasure running down his cheeks as he clung to
Lucifer desperately and moaned his name like a summoning spell. There was
literally nothing else in existence for him in this moment but the beautiful
bliss he felt and the strong hands on his body. He could barely breathe anymore
at this point, all the air seemed to have vanished or his lungs just weren’t
capable of getting enough oxygen anymore. That he didn’t pass out right there
and then was a mystery.
“Damn, Sam,” Lucifer murmured as his hands dug deep into Sam’s hair and he
pulled him up to him. “That was so damn good, you have no idea…”
“Oh, I have,” Sam gasped breathlessly, somehow managing to look up into
Lucifer’s eyes that were still darkened with lust and pleasure. “That was
fucking amazing.”
Lucifer pulled him into an utterly passionate and deep kiss that took Sam’s
breath away once more, leaving him moaning into the angel’s mouth as he slid
his tongue into his own. Even this kiss, one they had shared countless of times
by now, felt more intense and overwhelming than ever before. At the moment he
honestly hoped that Lucifer would never pull out and that he wouldn’t lose this
incredible feeling of being filled ever again. It wasn’t possible of course, he
knew that, but at the moment he didn’t care for that, just as he didn’t care if
he would be ever able to revert this de-aging spell.
Because honestly? His biggest fear had just turned into the most amazing sex of
all his life, even if he’d be stuck like this for the rest of his life he
wouldn’t give a damn anymore.
