****** Working My Way Up To Pure Sin ******

Summary
     Seven unrelated ficlets that I wrote for Wincest Love Week. Starting
     out mild and ending with PURE SIN
***** Bodyswap *****
Sam woke suddenly and immediately felt wrong. He blinked his eyes open in the
dark and tried to take stock of his mind and body to find out the cause of his
unease, but didn’t make it very far before he realized the problem.
His knees hurt. His knees ached like the early onset of arthritis. He could
also feel the throb of a cracked bone in his right middle finger. Sam opened
his eyes as his heart pumped faster and faster as he realized what had woken
him; he was not himself. He’d not thrown a single punch in the fight the day
before; Dean had. Sam didn’t have problems with his knees; Dean did. Sam didn’t
sleep in the bed closest to the door; Dean did.
“No more strange cases, man. This stuff is some bullshit.” Dean’s voice rang
out in the dark room, though Sam knew that he was the one that had spoken. He
rolled onto his right shoulder, wincing when he felt a broken rib on that side
that Dean hadn’t admitted to, and looked at his own body in the other bed.
“Dean, fucking wake up man.” Dean’s voice complained again and Sam watched, in
horror, as Dean woke up in his body.
He watched as his body flopped and floundered on the bed for a moment, “What’s
wrong with your voice? Wait. What’s wrong with my voice?” Dean lifted a hand to
his throat and felt a longer, thinner neck than he clearly expected. Sam
watched as his body sat up from the bed and turned to look at him with a look
of horror that he was sure he’d never made before; because it was his brother’s
expression on his face.
“What. The. Fuck.” Sam watched as his eyes fell to half-mast and his face went
into Dean’s unimpressed face. Sam shrugged and said nothing in reply, too
dumbfounded by watching Dean moving inside his body; bizarre on so many levels.
“Don’t make that face at me. I swear, my face can’t do the puppy dog thing like
yours can and it just looks fuckin weird. Get your ass up and lets find out
what the hell is going on and how to fix it.” He pushed himself up off the bed
and immediately stopped, looking down the length of his borrowed body to the
very clear erection causing his boxers to tent out. “C’mon Sammy, what’s… I
mean, really?”
Sam felt himself flush, something that didn’t usually happen so easily  in his
own body. “You’ll have to… It won’t just go away. I mean it’s really been a
while and, well, just go take a shower and take care of it.” He looked up from
the floor to see a peculiar look on his face. “What?”
“Sammy, I can’t use your body like that. I… can’t and don’t ask me to. It’s
gonna have to just go away.” And with that, Dean turned away and pulled Sam’s
jeans on up over his obvious hard-on and winced as he buttoned them. Sam
shrugged, right now it was only hurting Dean and honestly, he didn’t really
want Dean to see his body like that anyway.
Well, not if they weren’t there together. Sam had wanted Dean since he’d been a
teenager, but Dean had never given any sign that it was returned, so he’d
pushed it aside.
An hour of research yielded some results; the demi-god of balance they’d taken
out the day before had a history of taking couples and giving them the other’s
body so that they could operate more efficiently. It wasn’t a curse but a gift
and there was nothing they could do to fix it only wait it out.
Sam didn’t really see it as a gift. Aside from the bodily ailments that Dea’s
body had that he didn’t, Dean’s body worked differently than his own. Dean’s
body reacted to stimuli differently than his own. Dean’s skin was so sensitive
inside his clothes; it explained the way that Dean exuded sex all the time. Sam
turned to look over at Dean and sighed.
HIs body was still aroused; it hadn’t even dissipated a little bit. Dean was
shifting and twisting and the look on his face was pained. Sam wasn’t going to
be able to let his brother and his body suffer any longer. He screwed up his
courage and hefted himself out of the chair he was in and made his way over.
“You’re in pain.” He said as he rounded in front of his brother and crouched
down. His eyes were dilated and there were beads of sweat on his temples and
running down his long neck.
“M’fine Sammy.” Dean grunted out, shifting his hips in the chair again, making
the erection in his pants even more pronounced. “Just your gigantor body being
weird.”
Sam thudded down onto the floor on Dean’s achy knees and slid Dean’s hands up
his thighs, knowing exactly how every touch was like fire to his body right
now. He ran Dean’s thick, calloused fingers up to the waist of his jeans until
his own fingers gripped his wrists. He flicked his eyes up to meet his own
sunflower ones.
“Are you…” Dean trailed off and held his breath, his hips shifting again and
another giant droplet of sweat running down his neck. Sam nodded up at him and
flicked the button on his jeans open as he pushed up to press trembling lips to
the sensitive spot on his neck.
“We’re both in pain, lemme fix it.” He whispered and closed his eyes until he
felt Dean nod. He pressed another kiss to the skin in front of him then dipped
his head and kissed over the spot where his tattoo (and his heart) lay. He
kissed a line down the front of his shirt across his abs until he ended up back
at the top of his jeans.
He drew his cock out of the open flap of jeans and plaid boxers and blew across
the wet, red tip. He knew intimately what was going to feel good and he wasted
no time putting his knowledge to use. He put Dean’s plump lips on the glans
beneath the head of his cock and sucked and flicked his tongue there over and
over. He gripped the base of his cock hard and rubbed his thumb over the slit
as he sucked at the bottom of the head and the body beneath him jumped like
it’d been electrocuted.
“Oh fuck, oh Sammy, oh fuck.” Dean whined, his head rolling on the seat back,
eyes squeezed shut tight as his whole body trembled. It wasn’t going to take
much more.
Sam filled his mouth with saliva and slid his wet tongue down the seam of his
balls and underneath them, pressing hard with his tongue on the patch of skin
there as he jerked just the head of his cock and Dean was gone.
He came and came and came, all over his shirt, Dean’s face and hand while Sam
gentled him through it. After a moment, Dean’s eyes opened and looked down.
“Fuck I look hot all covered in your come, baby, “ He kicked out a leg, forcing
Sam onto his back on the floor while Dean crouched over him and proceeded to
return the favor. And when they woke up in the morning, tangled together, both
half dressed and sticky but in the correct bodies, they did it all over again.


***** Fake Relationship *****
“We have nothing going on, no one has any leads for us and we need the damn
money. I don’t see what the problem is.” Dean was not furious, but he was
getting there. His ears were turning red and his arms were crossed as he stood
in front of Sam, proposing what was possibly the stupidest idea he’d ever had
for them.
“Maybe if I speak slower you’ll understand. They want people in a  committed
romantic relationship.  We are  BROTHERS.  How can you not see the bad idea?”
Sam asked, pretty pissed off himself at this point. He knew his face was red
and his lips were pursed.
“Look, dude, we act for a freaking living, it’s part of what we do. PLus, there
is no couple in the fucking world that knows each other as well as we know each
other. It’ll be easy money for a few weeks. C’mon Sammy, you’re the one that
said you didn’t wanna scam credit cards as much anymore. Even with the bunker,
we gotta have money.”
Sam glared at his brother, listing off, in his head, all of the reasons that
this was such a bad freaking idea and the only one that he thought might make
Dean change his mind was the only one that he couldn’t bring up; he was in love
with his brother. Sam wasn’t sure if he could fake a relationship and not make
it any worse for himself but Dean was dug in about it so, as usual, big brother
got his way.
They signed up as Dean Smith and Sam Wesson, a ridiculous irony that neither of
them wanted to address but they’d never used those aliases before so they
figured it would have to work. The study was going to be for three months and
they couldn’t risk background checks being run on any of their known aliases.
They were set up in a small, three room apartment on the campus that the study
was being conducted on and encouraged to, as much as possible, go about their
daily lives. Since they didn’t actually live in Minnesota, that meant getting
short term work. Sam managed to corral a job in an off-campus library and Dean
found work as a mechanic one town over.
For the first week, it was no more awkward than any other job they’d worked
over the years; falling into their roles, each playing their part.
 At the end of each week, they had an appointment with the people running the
study, mostly just questions of the “how many times did you have sex this week”
variety, but with other, odd questions thrown in that left both brothers
unsettled. They spent thirty minutes together, then they each had a thirty
minute alone session with the doctors before they were released for another
week.
“Oh, gentlemen? We forgot to tell you, that the a/v department will be stopping
by on monday of next week, to install the cameras. Now, there’s no sound and
there will be no footage in your bathroom, but there will be cameras everywhere
else in your apartment.” The doctor announced off-handedly as they were leaving
from their first session.
Sam clenched his jaw so hard that he was pretty sure he cracked a tooth. He
allowed Dean to place a hand at the small of his back and they made their way
back to their temporary home. Sam was silent the entire way as he tried to
figure out how they would explain the fact that they’d been trading off
sleeping on the floor next to the tiny, queen-sized bed. Or, more horrific to
contemplate, how to fit the two of them onto a tiny, queen-sized bed. Once the
door to the apartment was closed, he rounded on Dean, but before he could say a
word, Dean held a hand up.
“Okay, this sucks. We’re gonna have to both cram onto that tiny bed when you
barely fit on your own. I know we haven’t slept together like that since we
were kids but ten grand, Sammy. Ten grand plus whatever we make from our legit
jobs while we are here, that covers a lot of expenses.” Dean said quietly
before dropping into the tiny chair in front of the giant tv  and going very
still. Sam closed his eyes and tried not to think about sleeping wrapped up in
Dean. He tried to think of all Dean’s disgusting habits all of the things that
his brother did that drove him insane instead of making him horny.
He couldn’t think of a single thing and sat down quickly to hide the thickening
cock in his jeans.
In the following few weeks, Sam realized what an amazing actor Dean really was,
because if he didn’t know any better, he’d think that Dean really was in love
with him. The little touches, the pet names, the genuine love in his eyes when
he realized that Sam made him his favorite dinner and a chocolate-cream pie for
dessert. “You tryin to get me to put out baby? I know I’ve been workin hard
lately but I always have time for my sweet Sammy. Bet you taste even better
than this pie.” He winked as he sucked chocolate and whipped cream off his fork
and Sam felt most of his blood rush south thinking about other things that
Dean’s mouth could suck.
In the end, Sam forgot about the worry. He forgot about the play acting. He
forgot about the cameras and the paid study. In the end, it was him and Dean,
just like always. It happened so naturally, what Sam had been worrying about,
that it felt like something they’d been doing all along.
Since they were forced to share a queen bed, they spooned together at night so
that they would both fit. And since Sam was four or five inches taller and
broader than Dean, it only made sense that he would be the big spoon; not that
Dean didn’t fight him on that. So they slept, with the heater off and the
window cracked open in the Minnesota winter, with Dean curled in Sam’s arms.
Sometimes, Sam forgot it was all a game, another scam they were running, but he
usually caught himself before anything could happen.
Until the night that he didn’t.
He woke up disoriented, and scared from a nightmare he couldn’t remember or put
words to. Half asleep and emotionally hurting, he felt a warm, comforting body
in his arms and knew he was with someone who loved him and would talk care of
him. It smelled like cold air and warm bodies and home and without opening his
eyes, he pressed his face forward and lay a line of kisses onto the hairline of
the person in his arms. They shifted back, closer to his body, rubbing what
felt like an amazing ass in his crotch. Then it was all over.
Sam moaned sleepily and humped his hips forward, slotting his boxer-clad cock
between the cheeks of the person in his arms. He didn’t notice that the body
went tense very briefly before a moan rang out in the room that wasn’t his. He
stopped thinking about it when the body rolled in his arms and he remembered
that it was Dean there; Dean tilting their heads together and pressing plump
lips to his own. Dean licking into his sleep-stale mouth and mapping it out
with his tongue. Dean tangling their legs together so that their cocks could
press together as they frantically dry humped and made out like teenagers.
And then, when Dean broke their kiss so that he could throw his head back and
moan Sam’s name at the ceiling as he came in his pajama pants, Sam responded by
coming harder than he had in years. They fell back to sleep among sticky shorts
and chaste, clinging kisses. When they woke in the morning, nothing and
everything had changed.
When they sat in their weekly appointment and were asked what had changed,
they’d suddenly become so much more affectionate and physical, Sam and Dean
smiled at each other and said that they’d merely rediscovered what they meant
to each other.
 
***** Broken A/C *****
It was so hard to concentrate as he watched another droplet of sweat roll from
Sammy’s hairline, down that long slender neck and into the already dark-with-
moisture and stretched out collar of his tee-shirt. It made Dean  thirsty  in a
way that was illegal. Not that Dean was overly concerned with legalities but
not only was Sam his brother but he was also his sixteen-year-old brother.
The heat in the crap-shack that their dad had stashed them in was oppressive
but, astoundingly, it was worse outside; Dean had no idea how people were
supposed to survive in South Carolina in August.
Well, he supposed, they had air conditioning. Sadly, the window unit in their
crap-shack had conked out the first night they’d been stuck there and Dad had
taken the car. Their only mode of (emergency) transportation was a beaten up
old ATV that Dean had his doubts would even make it to the general store that
was a couple miles away. But they couldn’t walk it.; there was no shade except
was was pathetically provided by the poorly pruned palm trees, which meant none
at all. Dean would fry like bacon if he tried to go outside during the day.
Another droplet of sweat rolled down Sammy’s tanned neck and Dean swallowed
hard; he had to find a distraction. His eyes flitted around the cabin for a
moment before, inevitably, getting sucked back in to Sammy. Sammy’s hand came
up to wipe at his sweaty neck before he grimaced and pulled himself away from
the chair he was melting into.
“This is gross, Dean. Didn’t dad mention something about a creek in the woods,
or something? I’m dying.” Sam whined as he pulled the sweaty tee-shirt over his
head and Dean’s twenty year old heart nearly stopped as all that tanned, toned,
sweaty skin appeared in his line of vision.
“I dunno if the ATV will make it Sammy and we can’t go on foot, it’s too fuckin
hot. But, if you really want to, run a cold bath and sit in it.” He replied
through parched lips, thinking about how satisfying it would be to run his
tongue over the trails of salty sweat on Sammy’s body.
“Ugh, fine, if that’s it.” Dean watched Sam peel himself off the chair he was
in and make his way into the tiny, windowless bathroom as he realized that he’d
just killed himself.
The bathroom was so small that you basically had to stand in the tub to shut
the door; and there was no window or ventilation fan so both boys had gotten in
the habit of leaving the bathroom door open all the time.
He swore to himself that he wouldn’t look. He shouldn’t look; it was wrong to
look. None of that mattered because once the water began to run in the old,
claw-foot tub, Dean couldn’t look anywhere else. He watched Sam peel his
sticky, sweaty, dirty shorts down his long legs. He watched as Sam bent over to
pull the shorts off over his giant feet and he got a peek at the shadowed
pinkness between Sam’s cheeks and the back of his low hanging balls. He heard,
with perfect clarity, the groan of satisfaction when Sam lowered himself down
into the cool water in the tub and relaxed back into it.
Dean looked down at his lap to see his cock clearly outlined in the boxers he
wore, the only thing he could bear to drag onto his skin in the unbearable
heat. He turned over and glared at the broken a/c unit in the window when he
heard another moan of happiness from the bathroom, his perverted ad overheated
brain easily turning it into a moan for something else. He ground his hand down
into his cock and his hips bucked up.
He looked at the a/c unit once more and came to a decision; that ATV was gonna
make it to town come hell or high water.
“Sammy, when you’re done, we’re gonna hit the library and the supermarket in
town.” He yelled down the hall, bucking his hips up into his hand once more.
“What for, Dean? Thought you said the ATV wouldn’t make it to town?” Sam yelled
back, a soft splash accompanying his words.
“Imma try and fix the fuckin a/c before I do something that we will both
regret.” Dean whispered under his breath as he pressed down on the head of his
cock and came in his shorts.
***** Let's Go To the Movies *****
All their lives, Sam and Dean have had their own language. Mostly it consisted
of body language and hand motions and obscure words and phrases that made sense
to only them. As they grew older, the communication evolved along with them.
When they began their relationship, it evolved even further. And to this day,
at the ripe old age of thirty three, an age that Sam never thought he would
reach, the phrase “let’s go to the movies” coming out of his brother’s sweet
mouth still makes his cock hard.
When Sam was sixteen and perpetually horny and the two of them had just begun
whatever it was that they were doing, they would tell their father, or Pastor
Jim, or even uncle Bobby, that they were heading out to the movies and they
would get in whatever transportation that was available to them and head out
towards whatever rinky-dink town that was nearby.
Sometimes, they actually saw a movie. Dean took him out to see “Star Wars: The
Phantom Menace” for a late birthday celebration before parking the car in a
field and letting Sam fuck him until they were both exhausted and covered in
spunk, sweat and saliva.
Usually though, it was code for “we gotta get out of here and fuck till we
can’t walk right.” Sam loved Dean’s body; it was his own personal playground
and he knew it inside and out after that year. He knew that Dean liked rough,
sucking kisses on his chest, and light, teasing scrapes of his fingernails down
his stomach. He knew that, just like most men, Dean loved a blowjob but when
Sam could get him to roll into his belly so he could eat him out, Dean could
come untouched like a girl and scream for more.
Dean liked their outings too. He liked getting all of Sammy’s firsts. HE’d been
there for the first step (towards him) and the first word (his name) so why not
first blowjob (given by him) and first fuck (his ass is amazing after all);
Dean never realized just how much he liked to bottom until Sammy and his big
cock came along.
 
***** Jealousy is a Bad Look on You *****
Sam has always been so beautiful. Dean has been watching him since he was a
baby and, even as a four-year old, Dean could appreciate what a beautiful baby
his brother was. He was a beautiful, dirty little boy and a beautiful, moody
teenager. When they began to travel together again after Stanford and so much
time apart, Dean looked more and realized that Sam was always the most
beautiful person in the room, inside and out. His long legs and broad shoulders
and tiny waist; the long hair and the tanned skin and his smile, oh lord, Sam’s
dimpled, the-sun-got-nothin-on-me smile. Dean didn’t just see the beautiful man
that Sam was; he wanted the beautiful man that Sam was.
After that realization, it was even harder to see Sam get hit on on the rare
occasion that he consented to hit the bars with Dean. He always had a polite
smile, and a gentle refusal for the person doing the flirting and Dean was
always mollified. No unworthy person in a bar in the middle of nowhere was
going to have any of his beautiful brother’s time or energy.
Then, one uneventful day in one random bar in one podunk down, Sam started to
flirt back. He smiled bigger and gently reached out to touch the, admittedly
very attractive man, on the shoulder. He tossed his hair, he laughed a genuine
laugh at what the man was saying.  Eventually, he looked over and raised his
eyebrows at Dean asking if he could have the room. Their hotel room; Sam wanted
to take this random person back to their hotel room and give him what was
rightfully Dean’s.
Dean pursed his lips and took his phone out of his pocket, faking a phone call
and holding one hand up to Sam across the smoky bar. He forced a shocked,
urgent expression on his face before closing his phone and pocketing it before
making his way across the bar. He clapped a proprietary hand on Sam’s shoulder
and turned to the man that Sam had deemed worthy of his affections, even though
he was mistaken.
“Sorry dude, gotta borrow your friend here. Sammy, we gotta take off. Urgent
business, you know?” Sam flashes a gorgeous smile at his friend before turning
a vicious bitchface at Dean, who doesn’t flinch, though he wants to. Sam lifts
himself from his barstool and turns towards the door, as Dean places a gentle
hand at the small of his back in a clear “MINE” statement.
The ride back to the hotel was silent and tense and Dean nearly began to feel
bad about what he’d done, but then he’d look over at Sam and think again that
man in the bar didn’t deserve to have any part of that beauty.
“What the FUCK was that, DEAN?” Sam shouted, slamming the hotel room door
behind him so hard that the headboard rattled against the wall. Dean shrugged,
facing away from his fuming, cock-blocked brother.
“No, you don’t get to just shrug and think it’s gonna go away. That’s not gonna
work this time, you owe me an answer.” Sam fumed stepping up into Dean’s
personal space and spinning him around to face him. “You look at me and tell me
what the fuck that was.”
Dean ground his teeth for a moment, meeting Sam’s eye in defiant silence. Their
normal way would be to fight, or for Dean to refuse to answer at all and then
they could be angry at each other for a few days. He couldn’t do it.
Instead of what he would normally do, he leaned forward and laid a kiss on
Sam’s angry lips. He pulled back but kept his eyes squeezed closed as he
answered, “he didn’t deserve you.” He was greeted with silence, and allowed
that to continue on for too long before he realized that he was not some
teenage kid with their first crush, but a grown adult and he opened his eyes.
Sam was smiling at him, a sassy twist to his lips. “Jealousy is a bad look on
you, big bro.” He smirked as he reached down and palmed Dean’s hips and pulled
him even closer.
 
***** Late Night Confessions pt 1 *****
“Alright, Bitch, truth or dare?” Dean asked and Sam looked into the darkness to
his left. He sighed and took another swig from the bottle of Hunter’s Helper in
his hand.
“Dude, what are you, twelve?” He asks, trying to inject lots of scorn, but
sadly what comes out is little brother whine.
“Sammy. The power is out and the Impala is grounded until we get the new
radiator in tomorrow so, c’mon, let’s play little brother. Truth or dare?”
Sam fell silent for a moment, taking another swig of whiskey before answering.
“Truth.” He prepared himself for something horrible, or something painful, or
something embarrassing so he was pleasantly surprised by Dean’s question.
“Why do you always eat salads when we go out? You used to love burgers and
greasy fries.”
Sam chewed on his lip for a moment before answering, fearing ridicule but he’d
promised truth and so truth Dean would get. “So when I...left for school, I
stopped doing a lot of the PT that dad had coached us to do, but I kept eating
the same way we always had and, well, you’ve heard of the ‘freshman fifteen’
and I put on about twenty-five pounds. I looked horrible and felt worse. So, I
started eating fresh food only and cut out shakes and fried foods and burgers
and started running gain and I didn’t stop until I was back down.”
After a moment, he finally got a response. “Nah, can’t picture you even kinda
chubby dude. You always think of yourself as chubby and..you weren’t even
chubby as a baby. Still cute kid though, before you became a Sasquatch.
Alright, your turn.” A loud gulp and belch ended Dean’s sentence and Sam
snorted with faked distain.
“Alright, Jerk, truth or dare?”
“Dare, of course.”
Shit, Sam hadn’t actually expected that. Okay, well, he will keep with the tone
of the evening so far; brotherly. “Alright, I dare you to come over here and
sit with me while we play this stupid game so we can actually see each other.”
A quick thud and a bounce of Sam’s mattress later and Dean’s face was
flickering right nearby in the light from his lighter. “Uh, not sure I’d get an
open flame so close to either of our breaths right now.”
“Pppft, whatever. Truth or dare?” Dean clicked his lighter shut and put it back
in his pocket.
“Truth.”
“So boring Sammy. Okay… when’s the last time you got laid? Actual sex, mind
you, not a back alley or a bathroom blowjob.”
Sam’s mind raced to remember and finally he realized just who and when it’d
been. He flushed in the dark as he thought about how to answer. “Well, it was
about three months ago in that little town in Vermont with the forest spirit.”
“Sammy, too long. I knew that waitress in that bar wanted you.”
Sam stayed silent; it hadn’t been the waitress, though she’d been pretty cute.
It had actually been the big, burly bartender; he’d bent Sam over the hood of
his truck and ate him out before fucking Sam so good he’d almost blacked out.
“It was the waitress, wasn’t it Sammy?” There was a tone to Dean’s voice that
Sam wasn’t familiar with and he felt backed into a corner for a second.
“Nah man, you got your one truth and now it’s your turn so; truth or dare?” He
could hear the calculating look on Dean’s face, but Dean abided by the rules of
the game.
“Truth.”
“Favorite sexual position.” Dean laughed and Sam heard the glug of him drinking
from his own bottle before he answered.
“Well, from behind and up against a wall is nice cause you’ve got so much
control over your thrusts, but I think I’ve gotta go with cowgirl. Nothing like
watching a nice set of tits bounce up and down and up and down right in front
of your mouth.”
Sam shifted in his seat, thankful for the darkness as Dean wouldn’t be able to
see the effect of his words on Sam. He had to agree, with a chick, he liked
cowgirl. WIth a dude, though, Sam had to give it to doggy style.
“Hello, earth to Sam? Truth (again) or dare?” Sam snapped back into the
conversation, realizing that Dean must’ve been trying to get his attention for
a little while.
“Alright, fine you big jerk, Dare.”
“I dare you to tell me about the last time you had sex. That time in Vermont.
The more detailed the better.” Sam rolled his eyes and chugged some of his
whiskey before leaning back against the headboard and crossing his arms.
“Pretty sure you don’t wanna hear this but alright, fine. The bartender. Big,
thick dude with the beard? Took me out back of the bar and pulled my pants down
as he bent me over the hood of his truck and ate me out like a gourmet meal.
Then he’d slicked up his, honestly a little disappointing size-wise, cock and
fucked me hard enough that my eyes rolled back into my head. I was so fucking
sore the next day, I have no idea how you didn’t notice.”
“Jesus Sammy.” Dean breathed wetly into the dark space between them. Sam felt
the mattress shift and then felt Dean’s leg against his own.
“Truth or Dare, Dean?”
“...truth.”
“Have you ever been with a guy?”
“Yeah, but I dunno if I like it as much as you do.”
“Well, see, i’m drunk enough now, so let’s just talk this out okay? I’m fully
bi-I like chicks just as much as guys. But I’ll tell you, I’m not normally a
bottom. I’m not opposed to it, really, but most dudes can’t make me come hard
like that. My bartender friend, now, he was an exception to that rule and a
pleasant one.” Sam leaned forward, placing his hand on Dean’s ankle under his
jeans and sliding it up his calf until he was trapped in the fabric. “But
you...oh Dean, you’re such a bottom that it makes my cock twitch.”
Dean sucked in a breath and Sam could feel his whole body shake.
 
***** Pure Sin pt2 *****
Chapter Summary
     This final part picks up where part 6 left off


Dean shifted his hips on the bed, trying to relieve the pressure on his trapped
dick just a little bit. Sam was hot like fucking fire and Dean had wanted him
for so long. To hear him talk dirty, to hear him talk about getting fucked and
to feel his giant hand on Dean’s leg was ramping up the tension in the room to
insane levels.
“What’s your favorite sexual act to have done to you Dean?” Sam asked and Dean
sucked in a short breath. He’s never actually said it outloud before, but if he
could tell anyone without ridicule it was Sam, tonight.
“I love having my nipples played with. Tweaked and pulled and pinched and
sucked on and bitten. Once, someone made me come just like that and sometimes,
I get hard just because my shirt is loose enough to rub across my nipples when
I move.”
Sam hissed and leaned forward even more, pulling his hand out of the leg of
Dean’s jeans so that he could put it just above Dean’s knee and feel the muscle
of his thigh. He blinked hard in the darkness and wished for a miracle that the
lights would come back on; he didn't’ want his first time with Dean to be in
the pitch black where they couldn’t even see each other.
“Oh fuck, big brother, that’s so hot. Wanna hear what I like?” Sam asked, his
voice pitched low and rumbly as he moved around on the bed so that he and Dean
were next to each other and he could lean in and speak right into Dean’s ear.
“I like my ass played with. I like to be eaten out like a girl till I’m sloppy
wet and pink and then I want you to finger me. I want you to spread my hole
open with two or even three fingers and then stick your tongue all the way up
inside of me and make me come on your face. Then, I want you to rim me till I’m
hard again so that I can flip you over and fuck that perfect, perfect little
ass of yours. Wanna make that bow legged walk just a little bit more
pronounced.”
Dean felt sweat pop out on his temples with the heat of that image. He wanted
that too; he wanted to taste Sammy. He wanted to do all of that and then offer
up his ass for Sam to do whatever he wanted. He realized, in that moment, that
the reason he’d never had all that good of a time bottoming was because there
was only one man on the planet that he trusted and it was Sammy.
“Oh fuck please. You gonna…” Dean gulped in a deep breath and licked his lips
again as he felt Sam’s giant hand ghosting over his chest, looking for his
peaked nipples. “You gonna do me bare, baby brother? You gonna come inside me
and make me all messy?” He gasped the words as Sam’s clever fingers found his
nipple and gently teased it, through his layers of shirts. He felt Sam’s breath
on his ear.
“Maybe I’ll even clean you up, Big brother. What about that?” Dean’s whole body
twitched in a shiver; he was so turned on that he was having trouble breathing
and they hadn’t even gotten their clothes off yet.
Though Sam was working hard at rectifying that. Sam pulled off Dean’s outer
shirt while he wasn’t really paying attention and slipped his hands up inside
of Dean’s tee-shirt, so that he could have a little skin on skin. Every
sensation was magnified by the fact that it was pitch black in the room. Dean
could smell Sam, his aftershave and shampoo and strong male sweat. He could
hear each breath that Sam took and was gratified by the fact that Sam was
breathing just as heavy as he was. Dean lifted his arms and Sam pulled his
shirt up and off him, baring his chest to Sam’s overly clever fingers.
Sam leaned down and sucked one of Dean’s pebbled nipples into his mouth and
Dean’s body twitched like he’d been electrocuted. Dean began to moan, loudly,
and squirm pushing both forward into Sam’s mouth and backwards to stretch out
across the bed. Sam pulled off to a loud whine from Dean and manhandled him so
that he was laying across Sam’s bed and Sam had better access to his whole
body.
“Oh fuck, baby yes. SammySammySammySam, fuck.” Dean whined as Sam lay so that
his leg was up over the bulge of Dean’s dick in his jeans as he sucked and bit
and teased Dean’s nipples. “I’m gonna come in my pants.” Dean whined again, his
back arching up off the bed as he let out a loud groan. Miraculously, just as
Dean began to come, the lights flickered back on. Sam was able to see, in
intimate detail, just how good he’d made his big brother feel. He slithered
down to the end of the bed so that he could look up the length of Dean’s whole,
flushed body.
“Dammit Dean, you’re beautiful like this. All strung out and all mine.” Sam
growled into the wet spot on Dean’s jeans. He flicked the button and pulled the
zip and gently pulled down the sodden boxers and jeans. “Damn, big brother, you
always shoot a load that big?” Sam asked, trailing his fingertips through the
rapidly cooling come on Dean’s hip and the tip of his still hard cock.
“Only when I’m really turned on.” Came Dean’s raspy voice after a moment. He
lifted up on his elbows to check out Sam now that the lights were back on. “So,
did you mean what you said you wanted?” He licked his lips, drawing Sam’s
attention away from his cock and to his mouth.
“I...yes, but I’m not too big to admit I’m not going to make it that long. I
don’t have the patience for that right now, after watching the show you put on
for me.” Sam panted, tearing his clothes off and tossing them around the room
until he was as naked as Dean and could slip back onto the bed. He lay across
Dean and contemplated for a moment.
“Have you ever heard of ‘hot-dogging’?” Dean raised an eyebrow, and shook his
head no.
“Roll onto your belly for me.” Sam husked, lifting up in a plank so that Dean
could roll over. He lay back down on Dean’s back, slotting his hot and heavy
cock between Dean’s perfect cheeks and began to rut.
Faster and faster Sam thrust his hips, fucking along Dean’s sweaty crack for a
long moment before his muscles seized up and he came all over Dean’s ass.
Pushing himself up, careful not to smear the come on himself, Sam shifted to
the side and scooped up his come from Dean’s cheeks, running it down his crack
and pressing it into the outer ring of his hole.
“I’m… I’m not sure Sammy.” Dean gasped, loving the feeling but wanting to pull
away at the same time.
“S’okay Dean, I dare you.”
