****** Witches Curse ******
by lovingsmutandfluff
Summary
     Sam and Dean come back from ganking a coven of witches, only to find
     out the next day that Dean was cursed by one of them, making him
     revert back to his sixteen year old body.
Notes
     This idea was stuck in my head for days so I decided to write it out.
     Planning to make this a series, but I don't know how often I will
     update it, due to I'm already working on a completely different
     series (and I'll be focusing on that more than this), but I'll update
     this from time to time.
     All mistakes are my own.
     I don't own anything or anyone.
“You sure you’re OK?” Sam asked, watching his brother flop down on one of the
hotel beds.
“Yeah, Sam. We got in, offed some witches, and got out and back to the motel
practically unscathed. I’m more than OK.” Dean insisted with a grin. He grabbed
the remote and turned on the TV, channel surfing.
“Yeah, but you almost wrecked twice.” Sam said.
“I’m just a little tired.” Dean shrugged.
“Don’t seem tired enough to want to fuck.” Sam smirked, motioning down to the
bulge in Dean’s pants. Dean had been casually stroking the hard-on he was
sporting. “Are you trying to seduce me?”
Dean gave another shrug. “Maybe. How about it Sammy?” He winked and a sly
smile.
“No.” Sam said. The smile left Dean’s face.
“What? Why?” He asked.
“Because I don’t know if something’s wrong.” Sam said.
“Nothing’s wrong!” Dean insisted.
“Right now. But you don’t know how you’ll be tomorrow.” Sam scoffed. “Tell you
what…if you’re absolutely fine tomorrow morning, we can fuck to your heart’s
content. But only after I see you’re fine.” Sam said.
Dean groaned. “But I have a stiffy now.”
Sam rolled his eyes and walked over to his brother. He crawled over him and
down to whisper in his ear.
“I may not fuck you tonight…” Sam said, a grin playing on his face. “…but that
doesn’t mean that I can’t help you out with your hard-on.”
 
Sam crawled back down to Dean’s pants, unbuttoning and unzipping them. He
looked up to see Dean watching him with lust-blown eyes.
Without looking away, Sam tugged Dean’s pants down and took the head of Dean’s
cock in his mouth, sucking lightly.
“Fuck…” Dean breathed out, head dropping against the pillow. “God, Sam. Feels
really good.”
Sam gave a small hum of happiness, and used his tongue to flick at Dean’s slit,
making the older Winchester moan.
Smiling, Sam started lowering him mouth on Dean’s cock, tasting the pre-come
that was starting to leak. He started humming and Dean moaned, lightly humping
into Sam’s mouth. The sucking increased as Sam reached to start playing with
Dean’s balls, teasing them lightly and making Dean squirm.
“S-Sam.” He panted. “F-fuck man…fuck…” Dean laced his fingers in Sam’s hair. A
rumble of a laugh emitted from Sam and Dean moaned in pleasure again.
“Not…gonna…last. Fuck. Sam. Gonna come. Fuck. Fuck…”
Sam’s administrations increased, and Dean started fully fucking himself into
Sam’s mouth now.
“Sam. Sammy. Fuck, Sam.” Dean keened underneath his brother and he came with a
cry, his brother’s name on his lips.
 
Sam sucked everything Dean gave, and pulled off with a wet pop, crawling back
up to Dean’s face, taking him in a kiss.
“See? Told you I would help.” He murmured against Dean’s lips. “And the sooner
you fall asleep, the sooner tomorrow can come and then I can fuck you senseless
into the mattress.”
Dean groaned and kissed Sam. “Fine.” He murmured, giving in. “I’ll sleep.”
Sam gave Dean a peck on the lips and got up, leaving to his own bed. He watched
Dean pull up his pants and get situated on the bed before Sam turned off the
light.
 
Sam was the first one to wake the next morning. It was still dark outside and
he could hear Dean snoozing away under his sheets. Sam gave a small smile and
got up and headed into the shower.
 
When Dean woke, the shower was running and Sam was missing from his bed. Dean
groaned and looked around, stretching and forcing himself to wake up for a new
day.
He felt great, almost like a million bucks. Last night’s rest seemed to have
done wonders on him. And Sammy would have to keep up his end of the bargain,
seeing how he felt better than before. Smiling triumphantly, Dean went over to
his bag and started pulling out some clean clothes for the day.
 
Sam was already hard, thinking about fucking Dean. Dean’s vocabulary always
became colorful, and he made the most pornographic noises when Sam nailed his
prostate.
He wrapped a towel around his waist, though it didn’t help hide his huge hard-
on he was sprouting.
Sam could hear Dean already up in the other room, humming some Led Zeppelin
song and moving around.
Alright, looked like he was going to need another shower after this, and he was
going to get to spend it with a certain someone.
He opened the door, and smiled, opening his mouth to say something when it
dropped.
“Dean?” He asked, shocked.
 
Dean turned around to see his brother, standing in the doorway to the bathroom
completely stunned.
“What?” He asked. Then he noticed his voice. It was higher than normal. He
cleared his throat and spoke again. “Why are you staring?” Still higher than
normal. “The fuck…?” He muttered.
He dashed past Sam and into the bathroom, looking at himself in the mirror.
“You’re fucking kidding me!” He yelled. “I’m a fucking teen!”
 
Sam had gotten dressed and was trying not to laugh, while he sat down at the
table, looking up different witch’s curses, trying to figure out how to switch
Dean back.
“This isn’t fucking funny, Sam.” Dean growled.
“Never said it was.” Sam said, keeping his eyes focused on the laptop. A small
grin emerged on his face, and Dean growled again.
“You’re fucking laughing at me, Sam!” He yelled. “How are we gonna change me
back? We ganked all the witches.”
“I just have to find a spell. Once I do that, we can look for someone who can
change you back. But it’s gonna take a while. The coven we found practiced some
seriously old magic. You might be stuck in that body for a little while.”
“Fucking dandy.” Dean muttered, grabbing a beer. “How old do I look anyway?”
“Fifteen or sixteen.” Sam said, glancing up and cracking a smile again. “It’s a
little funny.” He said.
“No. It’s not.” Dean said. He took a chug of beer and sighed. “I’m never gonna
get back to my normal body, am I?”
“Never say never.” Sam said, clacking away on the laptop. “Though…” He looked
up and glanced out the window. “We should probably get out of here, before the
actual cops start showing up to investigate the witches disappearance.
“Sounds good to me, I’ll just get a shower at the next motel.” Dean sighed. He
pulled out the keys to the Impala, and started making sure everything was
packed away.
“Whoa…wait. I don’t think it’s a good idea if you drive the Impala.”
“What? Since when?” Dean asked.
“Since you gained the body of a teenager.” Sam said.
“No. It’s my car.”
“Dean…” Sam sighed.
“No!”
 
“I can’t believe you’re fucking driving my baby.” Dean muttered, getting into
the passenger’s side of the car.
“You’re wired up.” Sam said. “You no longer have a valid license to use because
of how old you look now, so if we get pulled over because you’re speeding…then
both of our asses are on the line. I’m not risking it.”
“Whatever.” Dean sighed.
Sam pulled out of the parking space and he drove away from the motel.
 
They drove a few states away and into a new motel, it was already night and
Dean was getting antsy. Once Sam got a hold of a room, Dean dashed inside and
into the bathroom, taking a shower.
Sam only shrugged and settled down, starting his search again.
 
Sam heard the shower shut off and he glanced up to see Dean waling out of the
bathroom, stark naked, rubbing a towel on his hair.
“Dude!” Sam said.
“What? It’s not like you’ve seen me naked before.” Dean shrugged. “Besides, I
don’t think most of my clothes will fit now.” He started looking through his
clothes, managing to find a pair of boxers that had shrunk in the wash. “I have
boxers and loose t-shirts. But I don’t have any pants.”
“I’ll buy you some clothes, then.” Sam said, getting up. “And I’ll get us some
dinner while we’re at it.”
“Wait…if I seem to remember, you still owe me a fuck.” Dean said.
“What? No.” Sam said.
“Seriously? Is it because I’m in a younger body? Let me tell you something Sam,
whatever you dish out, I can take.”
“It’s not the body I have a problem with Dean. It’s the fact that if we get
caught, I get arrested. Last I remember, you weren’t the quietest person to
have sex with.”
“Come on Sammy! Where’s your sense of adventure. We can be careful, I swear.”
“No, Dean. Besides, I still have to get clothes for you and dinner. Just stay
here and doesn’t cause mischief.” Sam said, grabbing the keys to the Impala and
heading out the door.
 
Sam couldn’t have been gone for more than 30 minutes, but when he got back to
the motel room, Dean was gone.
“Damn it, Dean. Where are you?” Sam muttered. He tossed Dean’s clothes on one
of the beds, and placed the food down on the table, then left to start
searching for Dean.
Sam found him in a small bar/arcade, fully dressed in baggy clothing, and
flirting with a teenage girl.
A pang of jealousy and annoyance ran through Sam and he walked over to them.
“Dean.” Sam stated, shoving his hands into his pockets, so he didn’t strangle
Dean. “I told you to stay in the motel room.”
“Sammy, hey!” Dean said, turning to face his brother. He had a huge smile stuck
on his face. “Meet Veronica.”
“Victoria.” The girl corrected.
“Right, Victoria. She was just telling me about-” Dean was saying.
“I don’t care.” Sam said. “I told you to stay in the damn room. I have dinner.”
“Right. Later, Victoria.” Dean turned and winked and another pang of jealously
shot through Sam. He grabbed Dean’s shoulder, and pulled him out the door and
back to the room.
 
“What the fuck was that about?” Sam growled, pinning Dean against the wall once
the door shut.
“What, Victoria? Just talking to her Sam.” Dean smirked.
“It looked more than ‘just talking’.” Sam said, pressing close to Dean.
“Well, I have to get all this sexual teenage hormones out somehow, seeming how
you’re being too much of pussy.”
“I’m a what?” Sam asked, his voice going dangerously low.
“Pussy.” Dean said, staring Sam in the eye.
“Fine.” Sam backed up and grabbed Dean by the shirt, pulling him onto the empty
bed. “Start stripping Dean.” He ordered, yanking his own clothes off.
Dean turned away, smirking, and started to strip as well.
 
Sam grabbed the lube and coated his fingers with it, before he leaned over
Dean’s back and pressed close to his ear.
“By the way. I saw that smirk. I know you were flirting with that girl to get
me riled up.” Sam whispered. “So, I have my own little surprise. You aren’t
allowed to make any loud noise.”
“Wait, what?” Dean asked, turning to look at Sam.
“No loud noises Dean.” Sam smirked. “You get too loud, I don’t care what I’m
doing, I’ll stop and put you over my lap and spank you.”
Dean’s eyes narrowed, studying his brother’s gaze. “You’re bluffing.”
“Try me.” Sam said before moving back to Dean’s ass.
He rubbed a finger against Dean’s hole before plunging in.
 
“Fuck, Dean. You’re tight. Almost virgin tight. Damn, feels good.” He murmured
into the small of Dean’s back as he wiggled his finger around Dean’s tight
channel, making Dean squirm and give a soft moan.
Dean quieted and turned around to look at Sam with wide green eyes.
“Not in trouble Dean.” Sam murmured. “Only if you get too loud.” Sam started
wiggling another finger in and Dean’s head dropped, and he humped back on Sam’s
fingers.
“Fuck, Sam.” He murmured. “God.” He groaned softly. Sam started fucking in
Dean’s ass with his two fingers, scissoring and stretching Dean’s hole. He
found Dean’s prostate and he pressed lightly against it, watching Dean press
his face into the pillow to muffle the moan that came out. “Damn it, Sam. How
the fuck am I supposed to stay quiet if you keep doing shit like that?” Dean
asked, turning his head to look back at his brother.
“Find a way.” Sam shrugged, with a grin. “Gonna add another finger Dean.”
“Fuck.” He breathed out, feeling the third finger finding its way into Dean’s
tight, warm channel.
“God, Dean. It’s gonna feel so good fucking into you. So tight and warm. Fuck!”
Sam said. He stretched his fingers out and brushed against Dean’s prostate
again.
“S-Sam.” Dean moaned, shaking and withering.
“What is it, Dean?” Sam asked.
“Fuck me already!” Dean said, fucking back on Sam’s hand. “Please!”
“You think you’re ready?” Sam asked, teasingly. He pulled his fingers almost
all the way out before thrusting back into the warmth.
“Yes!” Dean said, gripping the sheets. “Fuck!” He was starting to get louder,
but Sam let it slide this time. He would probably be fucking him by the time
Dean managed to completely slip and break Sam’s rule, and Sam couldn’t wait for
that moment.
“Alright, Dean. I’m gonna give you what you want.” Sam whispered in Dean’s ear,
while he lubed up his aching cock. He slipped his fingers out and shoved his
cock in before Dean could make any noise. He pulled back, with the head of his
cock catching on Dean’s rim, and he thrust hard, hitting Dean’s prostate.
 
Dean looked made a strangled noise, and pressed his face into the pillow,
grunting and moaning, while Sam thrust ruthlessly into Dean.
“Fuck! Sam!” He moaned into the pillow. “Fucking hell!”
“Feels so good though, doesn’t it Dean?” Sam asked, his voice an octave lower
from want and lust. The thought back to the girl that Dean had been flirting
with. “Dean, I want you to understand something.” He grunted, pressing down on
Dean’s back, placing his arms on each side of Dean to keep balance, so Dean
didn’t have to take all the weight. “Are you listening?” Sam asked, emphasizing
with each thrust.
“Y-yeah. What, S-Sammy?” Dean said turning his head. His mouth dropped in an
‘O’ and his eyes shut, as Sam refused to slow down his pace.
“You don’t flirt with other people. You’re mine Dean.” He growled in Dean’s
ear. “I fuck you, and sometimes you fuck me. But no one else gets you or gets
to fuck you. Understood?” He asked, thrusting in hard.
“Understood.” Dean breathed out, making small strangled noises to keep his
voice down.
“Good.” Sam said, biting and sucking the nape and the place where Dean’s
shoulder and neck met.
“Fuck…Sam…Sammy…fuck…gonna come. Fuck!” He yelled out loudly. Suddenly, Sam’s
hand was wrapped around the base of Dean’s hard cock and he stopped moving.
Dean’s eyes went wide, realizing what he did. “Sammy…shit, Sam…I didn’t
mean…I…”
Sam pulled out and before Dean knew what was happening, he was laid out across
Sam’s naked lap, his arms pinned down to the small of his back and Sam’s hand
resting on his ass.
“Sammy…” Dean said, squirming around.
“No fighting Dean. I told you not to make any noises, and you did. How many do
you think you should get?” Sam asked.
“Uhh…” Dean looked at Sam with wide eyes, mouth gaping. He knew that if he went
to low, then Sam would raise the number, but if he said a number to high, then
Sam might actually give him that many. “Ten?”
“Is that a question or an answer?”
“Ten. Ten, Sam.”
Sam considered it, and nodded. “Ten.” He said. Without warning, his hand rose
and came crashing down on Dean’s bare backside. “One…” he said. Smack. “Two…”
Smack. “Three…”
 
Dean gave a soft whine by the time Sam had gotten to seven. Sam wasn’t holding
anything back, and it fucking hurt.
“Only three more Dean.” Sam said. He brought his hand down on Dean’s red ass
with a loud smack.
“Fuck.” Dean hissed out.
Sam brought his hand up and brought it down again, watching Dean’s red butt
jiggle as the smack resounded in the room. He did it one more time and released
Dean from his hold.
“No more loud noises?” Sam asked.
“No more, Sam.” Dean said. Sam pulled Dean back on the bed, only this time,
placing him on his backside. Dean hissed out in discomfort, and squirmed around
a little. “Sammy?”
“You’re not coming on my bed.” Sam scoffed, before sinking back into Dean’s
channel. Dean pressed his hand to his mouth to soften the moan that rose.
Sam started thrusting, picking the pace from before back up.
“Gonna make sure you feel this Dean.” Sam said, looking down at his brother.
“Make sure you remember not to flirt around. Gonna come in you Dean. Then I’m
gonna plug you up.” Sam grinned dirtily.
“Fuck Sam…god. Feels so good. Fuck.” He rolled his hips as well as he could
from his position. “Fuck, Sam…Sammy, Sam…fuck…gonna come. Need to come.” Dean
moaned. Suddenly, he clenched around Sam’s cock, and his back arched.
Sam pressed his hand over Dean’s mouth as Dean came with a cry, his come
hitting his stomach and Sam’s. It was enough for Sam to be pushed over in his
orgasm, and he came inside Dean.
“Fuck Dean.” Sam murmured, before pulling out. He maneuvered Dean’s hands to
hold his ass cheeks together. “Don’t let any of my come spill out. Sam walked
over to his bag and pulled out a bright blue butt plug, holding it out so that
Dean could easily see it as he walked back over.
He moved Dean’s hands out of the way, and worked the plug in.
“There you go.” Sam smiled. He leaned down and licked up all the come that had
splashed on Dean’s stomach. “Clean me up, and then we can heat dinner up. It’s
probably gotten cold.” He motioned to the food on the table.
Dean moved and quickly cleaned up Sam’s stomach and cock, making Sam groan.
Once he was done, he pulled back and walked over to his bed, leaning down and
making sure Sam could see the butt plug.
“Fuck Dean.” Sam scoffed, as he pulled on his own clothes. “You’re just trying
to get me hard again, aren’t you?”
“Maybe.” Dean shrugged, pulling on some new clothes. “Now you were talking
about dinner?” He smiled.
