Summary
     I wrote this a long time ago and am just now posting it because I
     just made this account, so I hope it's not too terrible. First time
     weecest. Panties. Dirty talk. Enjoy, fellow sinners.
Sam had always looked up to Dean. It was totally normal for a kid to look up to
his older brother. Especially considering that growing up the way they did,
they didn't have much more than each other. Of course, it was probably a little
less normal for Sam to have a huge fucking crush on his brother. He'd never
tell anyone. He wouldn't even let himself write about it in his journal for
fear that someone might read it.
It had all started when Sam was 12, and Dean was 16, and Sam had gotten home
from his friend's house a few hours early because his friend had gotten sick.
He had walked in on Dean jacking off to a Playboy magazine. It was an event
they had both agreed to never talk about. But even now that it was two years
later, Sam couldn't help but think about it. He knew it was wrong, he really
did.
But sometimes when he was touching himself, the image of Dean's plump lips
shaping a perfect "O" as he moaned with pleasure jumped into his mind. And when
Sam was close to coming, sometimes he would imagine that it was Dean's hand on
his cock instead of his own. He had dreams about what his big brother would
taste like, about how Dean's lips would feel wrapped around his cock. This was
Sam's biggest secret. Well, this, and the fact that he wore panties sometimes.
He only had a couple of pairs because he couldn't stand the humiliation of
standing in line at fucking Victoria's Secret with a handful of lacy panties
more than twice in his life. He was wearing a pair as he was thinking about all
of this, daydreaming in algebra class. The lace didn't feel scratchy against
his skin like he once thought it would; no, it felt so good. The fact that he
was wearing a little pair of black, lacy panties beneath his jeans made him
feel so naughty, so- "Mr. Winchester?" Sam's head snapped up from where it was
resting on the table previously, and he locked eyes with his math teacher, a
rickety old man named Mr. Long. "Uh, yeah?" Sam asked, face beginning to burn
with embarrassment at being caught not paying attention. "Mr. Winchester, I
asked you a question. This is the second time today that you've decided not to
listen to my lesson, and to be frank it is getting quite irritating." "Sorry,
sir," Sam winced and looked down at the floor. The rest of the class went by
fairly quickly, and soon enough, the bell rang. Sam hurried out of the room to
avoid a lecture on paying attention, and went to his locker. He grabbed his
backpack and began to walk back to the motel he and Dean were staying in while
their dad was on a hunt. Once he arrived, he flopped down on the bed that he
and Dean were sharing since their dad was too cheap to get a bigger room, and
stared at the ceiling. He was trying not to think about what he was wearing
underneath his jeans because he knew Dean would be getting home from high
school in less than an hour and he didn't want to risk being caught jerking off
in a pair of fucking panties, for gods sake. Still, he could feel his cock
aching. Maybe he could jerk off, considering that Dean wouldn't be home for
about forty five minutes? He would have time. He would have lots of time. He
sat up and scooted to edge of of the bed so he could take his jeans off. He
pulled them down, a tiny moan escaping him as the rough fabric brushed against
his panty clad cock. He discarded his pants on the floor and lay down on the
bed, head propped up against a pillow. Moaning slightly as blood rushed to his
cock, he teased himself by lightly trailing his fingertips up the insides of
his thighs, relishing in the delicious feeling of finally touching close to the
area he wanted to touch so badly. After a minute or so of teasing himself, he
couldn't take it anymore. He needed to touch himself. He stroked slowly up the
lace covering his length, moaning as he felt how hard he was. He grabbed the
base of his and cock and started slowly jerking himself off through the
material. He imagined Dean laying on the bed next to him, getting him off,
kissing him roughly as he did. He began to rub faster, and before he could stop
it, the name "Dean" slipped from his mouth softly. His eyes shot open. 'No!' he
thought to himself. What if someone heard him? But his dick had jumped when
he'd said his brother's name, like it made the fantasy a little more real. Dean
still wouldn't be home for a while, and it had felt so good. He touched the
head of his cock, poking out from the top of the panties. He felt the precum
that was leaking from the head of his cock, and he smeared it around on his
hand. He pulled the panties down so that his dick was free and they rested just
under it, and he began moving his hand again, using his precum as lubricant.
His breathing intensified once again, and he cried out loudly as he rubbed the
head of his leaking dick. He arched his head back, groaning as he thought about
Dean's huge cock; thought about it pounding into him. "He whined his brother's
name again, loudly. He screwed his eyes shut in pleasure. He moaned as he
approached his climax, jerking his hand hard as he felt himself reach the edge.
Dean's name was on his lips as he came all over his belly and the panties and
the bed sheets. He lay there for a moment, still loosely pumping his cock,
savoring the orgasm. He slowly opened his eyes, sitting up so he could begin to
clean up his mess. He glanced around the room, trying to find a towel, and then
he saw him. Dean was standing in the doorway. Staring at Sam. And Sam was
wearing panties, and covered in come. "Sam?" Dean croaked weakly. "Shit, Dean,
I'm so sorry, I didn't think you'd be home, I'm sorry," Sam rambled while
pulling his pants back on, wiping the come off of his chest and stomach with
the back of his hand. "Sammy, were you... Were you saying my name?" Dean asked,
his voice cracking. "It doesn't matter, I'm sorry," Sam muttered, his face red.
He stood up, ready to lock himself in the bathroom so he wouldn't have to face
his brother, when Dean spoke again. "Stop. Sit back down." Sam shook his head,
trying to fight back tears. "Dean, I don't want to talk about it." "I said, sit
down." Dean said, raising his voice. Sam sat on the edge of the bed, come
soaking through his jeans. "Dean, I'm-" Dean cut him off by walking to the bed
and pressing his lips against the younger boy's. Sam pulled away, looking
confusedly at his brother. His eyes held a question, and Dean answered by
pushing him down roughly onto the bed so that he was straddling his hips. "You
think the same way about me, huh? Sometimes when I'm inside of girls, I imagine
that I'm inside your tight ass instead. I never let myself act on the urges
because I didn't think you'd feel the same way, but," Dean smirked as he kissed
down Sam's jaw, "you do." The younger boy moaned, bucking his hips up, trying
to get some friction between his and Dean's cocks. "I wanna see your panties,
Sammy," Dean breathed against Sam's neck. "I want to see how your cock looks in
them." Dean rolled off of his brother and roughly fumbled at the button on
Sam's pants, sucking in a sharp breath once they were on the floor and he had a
full view of Sam's slutty, lacy panties. "So beautiful," he breathed. "When I
opened the door, and I saw you there, moaning and writhing, you got me so hard
Sammy. And when you came saying my name? I don't think I've ever been so hard
in my life." He angled his hips down so his erection pressed into Sam's upper
thigh. "You feel that? You feel what you do to me?" He stared into Sam's eyes,
waiting for a response. No words came. Instead, Sam grabbed Dean by the
shoulders and pulled him down so that he was laying on top of him, and he
pressed his lips against Dean's. Never breaking the kiss, Dean moved them so
that Sam's head was on a pillow and Dean was completely on top of him, kissing
him hard. Dean's lips tasted like cherries and fresh air, and Sam couldn't get
enough of it. He kissed Dean like it was the last thing he would ever do. Even
though he had just came, he felt his cock slowly hardening again. He squirmed
underneath his older brother, pressing his hips up, trying to get a relief to
the ache. Dean growled, bucking his hips down to grind his cock against Sam's.
The friction wasn't enough, for either of them. "Need, more," Sam panted. Dean
sat up, breaking the kiss, and Sam whined. "I'm just taking my pants off, stop
being a slut," Dean laughed. A soft moan escaped Sam's lips. "You like that?"
Dean realized. "You like being called a slut?" Sam nodded, his cheeks a dark
red. Dean smirked. "You like wearing those lacy little panties, like thinking
about getting fucked in them? You like being a little slut for your big
brother?" Sam exhaled sharply and put his hand on his cock, trying to find some
relief. Dean slapped his hand away. "Don't touch yourself. I'm going to do that
for you." Sam whimpered. Dean finished pulling his pants off, shoving his
boxers off along with them. Sam stared at his huge cock, a burning hunger in
his eyes. "Dean, please..." " What do you want, Sammy?" "Want you," Sam whined.
"Want me to do what? Say it. I want to hear you say it." "I want you inside of
me," Sam said softly. "What was that? I didn't hear," Dean's lips twitched,
fighting back a smile. "Dean, please, just fuck me. Please, Dean." A look of
pure need flashed across Dean's face, his eyes dark. "Flip over onto your
stomach," he ordered. Sam did what he said, his length now pressed into the
bed. He wanted so badly to grind into the mattress, but he knew that if he did
Dean would be angry. Dean sat down on the bed beside him and circled his hole
with his index finger. "More," Sam whined. "We can use the crappy lotion in the
bathroom as lube." "I have another idea," whispered Dean. He pushed two of his
fingers into Sam's mouth. "Suck." Sam was happy to obey. He sucked on Dean's
fingers, swirling his tongue around the tips. Dean groaned, then pulled his
fingers out. "Good slut, sucking on my fingers like they're my cock, got me so
hard baby." Without any warning, he slid a finger inside of his brother. Sam
winced at the sudden intrusion, but moaned as Dean's finger slipped further in.
"More," he panted. "Are you sure?" Dean asked. "More!" Sam said louder. Dean
shoved another finger inside of him, drawing out a loud sound of pleasure from
his little brother. "You like that?" Dean breathed, his voice low and velvety.
Sam wasn't capable of an answer, only of moans. "Like my fingers inside of you,
opening up your hole so I can fuck your tight ass?" Dean scissored his fingers,
hitting the fleshy patch that he knew would make Sam go crazy with need. Sam
balled up a handful of blanket, squeezing it as a huge wave of simultaneous
pain and pleasure washed over him. "Need you...Dean, please, need you." Dean
pulled his fingers out, causing Sam to whine at the empty feeling. "Flip over,
I want to see your pretty face as I fuck you." Sam did as his big brother said,
and the rapidly growing spot of precum staining his panties was apparent as he
spread his legs wide, eyes pleading. Dean kissed him once, a light kiss that
made Sam's spine tingle, then pushed Sam's panties to the side so he could line
himself up with Sam's entrance. He locked eyes with Sam, and slowly began to
push into him. Sam felt as if he was on fire inside, but the pain felt so good.
"Oh, fuck, Sammy, you're so fucking tight, feel so good," Dean groaned as he
pushed all the way in so that he was completely inside of Sam. "So full...I'm
stuffed so full of your cock, Dean," Sam moaned, his eyes screwing shut in
pleasure. Dean grunted at Sam's words, pulling out almost all the way then
slamming back in hard. Sam cried out, reaching back to grasp the headboard as
Dean pounded into him. "Harder," Sam whispered, mouth opened in a silent moan.
Dean grit his teeth and slammed into his baby brother so hard that the bed
shook. Sam yelled. "Right there! Oh my God, right there!" Dean knew that he'd
hit Sam's prostate by the way Sam was reacting, and he wanted to hit it again
and again and again until he passed out because the look on Sam's face was
gorgeous. He changed their position so that Sam's leg rested on his shoulder
and kept fucking into him. The angle he was at made sure that he hit Sam's
prostate with every thrust, and Sam's grip on the headboard tightened as he
began to moan so loudly Dean was sure the whole motel could hear. On a
particularly hard thrust, Sam screamed. It wasn't just a yell; he screamed.
Dean could feel Sam's cock bouncing up and hitting his stomach with every
thrust, hard and leaking. He wanted Sam to come so hard that he wouldn't be
able to move for an hour afterwards. He reached a hand down to Sam's cock,
loosely jerking him off as he pounded into him. Sam's member was throbbing.
"I'm gonna, oh fuck, I'm gonna come, I'm so close, Dean, I'm gonna come," Sam
moaned loudly. "Come all over my hand, Sammy. Wanna feel you lose control,
wanna see your pretty face when you're pushed over the edge." Dean slammed into
Sam as hard as he could; nailing his prostate. Sam screamed his brother's name
as he came, hot spurts of come covering Dean's hand and their stomachs. He
clenched around Dean, making the older brother groan with pleasure. The look on
Sam's face made Dean see stars; it was a look of pure bliss and need. His gasps
and moans filled the room. "Fuck, Sammy, seeing you like this, it's so
fucking...ah, I'm so close, I'm so close," Dean moaned loudly as he continued
to slam into Sam. "Come inside me," Sam panted. "Want you to come inside me,
Dean." His words set Dean over the edge, and with one last thrust, his orgasm
hit him, more intense than any he'd ever had in his life. He fucked loosely
into Sam as he rode out his orgasm, then collapsed on top of him, breathing
hard. Once he could move again, he pulled out and rolled off of Sam. His little
brother was laying there, eyes lidded and mouth partly opened, slutty black
panties stained with come. More come streaked his stomach and chest. "Dean..."
Sam whispered contentedly, and reached to take his brother's hand in his.
Instead, Dean leaned over and placed a gentle kiss on Sam's lips. When he
pulled away, Sam breathed out a soft 'no'. He pulled Dean back down and kissed
him again. They kissed for a moment or two, softly but passionately, and then
Sam pulled away. He pulled Dean closer, and whispered in his ear. "I love you."
Dean laughed, and nuzzled his head into Sam's neck. "That's so gay, man." Sam
pressed a kiss to the top of Dean's head. "So was that." "Bitch." "Jerk."
