Summary
     Dean fucks himself to thoughts of the impala taking him rough from
     behind, while also using memories of past experience with Sam in the
     backseat to fuel his desire.
Notes
     Truthfully, I've wanted to write this for a while now, so here it
     finally is. I encourage you dimpala shippers to read.
Baby. The term associated with lovers. A term used for significant others.
 
My baby.
 
Dean leaned against the hood of the Impala, stroking the smooth hood and
feeling the heat from the long-haul engine soaking through the metal and into
the palm of his hand. He trailed his fingers delicately over the mirror and
across the cool glass of the window, tracing designs in the mist formed on her
shielding and bringing his hands down towards the rear seat handle. Baby
responded in kind, engine purring as he moved slowly and controlled, building
up the tension as best as he knew how.
 
Dean pulled on the door handle, running his hand up and down along the
stainless metal as if it was one of baby's most intimate parts, allowing him
access into her body. He slid into the leather slowly, working his whole body
across the worn black leather and dragging his hips cathartically along the
seats where his baby brother spent most of his childhood, and even spent his
first orgasm crying out Dean's name with a bite to the tongue. Just the thought
of him taking Sam's precious little virgin ass for the first time in that very
seat made him moan, a hot spike of arousal easily shooting through his veins
like his own brand of heroin. The car still vaguely smelled like sex from their
last run, intensifying the pleasure felt now with all the memories of exploring
himself with the comfort his baby.
 
He pulled his shirt over his head slowly, trailing his hands across his chest
and pinching a nipple once he was free of his cotton blockade to the sun-kissed
planes of his own skin. His jeans came next, button popping open swiftly and
zipper drawing down with a soft hiss as it went over the forming bulge in his
black satin panties he'd picked out just to match with his baby.
 
Dean slid the jeans down around his thighs, dipping his hands under the panties
for a quick tease to his filling cock before kicking his pants off all the way.
He dragged his nails along the leather upholstery, knowing he'd be driving baby
mad with his teasing if she could feel. A cold chill ran up his spine and he
shuddered, loving the temperature of the autumn night creeping in through the
window. Dean groaned at the thought of someone overhearing them sharing this
moment together, like how he and Sam would pick people out in the gas station
parking lots as the fucked rough and hard enough to rock the impala on its
wheels.
 
He swirled his hand around the corse pubic hair poking out of the lace
decorating the panties, coaxing the head of his cock to make an appearance out
of its lacy confines once it was fully hard with arousal. Dean ran a knuckle
from his balls up to just below the head, shoving a fist in his mouth to create
a sharp hiss at the sensation of being marked while making love. Baby put in
effort to help strengthen Dean's provocation by rattling the whole car with the
engine's power like the powerful top Sammy had become that turned Dean on in
ways his little brother shouldn't.
 
Dean pulled the panties off, kneeling on the leather seat with his legs spread
out as if he were a whore begging for his next tip at a brothel. The air gave
him a rush of feeling open and exposed through his legs, to which he moaned at
the thought of being on display privately for his baby. He grabbed the bottle
of lube stored under the driver's chair and eagerly poured the viscous liquid
into his palm, heating up the liquid as he began to slick his fingers planning
to breach the most private area Dean had. One finger swirled around his
entrance as another traced lightly up and down his perineum, leaving trails of
lightly coated lube as a design only to be seen by those most intimate to him.
Dean used his other hand to roll one of his balls in his hand, massaging the
sensitive skin to send shock after shock of pleasure through his aching cock
that begged to be touched.
 
He pushed the finger dancing across his hole in slowly, gently applying more
and more pressure until he breached the taught muscle and could feel the
fluttering of the soft inside. Dean moaned when he reached a knuckle deep and
began pumping in and out, expanding himself to fit his finger up to two
knuckles. He added a second finger, hissing at the mix of pleasure and pain
that shot through his ass and to his cock at his body's response to the
intruding digit. Each pump sent his muscles fluttering and trying to adjust to
the scissoring motion he added to each thrust.
 
Dean withdrew his fingers with a pop, sticking them in his mouth with a moan
just imagining his baby sticking her worn fingers on his tongue for him to
taste himself. He lapped at the digits and pulled out the box from under the
passenger seat concealing his brand new vinyl black dildo just perfect for
matching the impala's being. Dean slicked it up with lube, running his tongue
along its smooth shaft and groaning around the head. The dildo filled a good
portion of his mouth, making it easy for him to suckle it with special
attention to where the sensitive glands would be located.
 
He pulled the toy out from his mouth and aligned it with his hole, watching
himself in the rearview mirror and staring as if his baby was eagerly staring
back. Dean pushed the dildo in slowly to savor the feeling of being violated by
this toy. His muscles quivered around the intrusive item, dancing along in a
most sinful way. He moaned when it sunk all the way in, filling him with the
full vinyl of his baby.
 
Dean moved off the seat and perched himself on the floor with the driver's seat
right in front of him, perfectly in line for him to rut against the cool
leather while he fucked himself from behind. He moved the dildo faster,
adjusting the angle to hit that sweet spot just enough to give him the extra
pleasure he needed to lift his rutting ecstasy into overdrive.
 
Dean came with a loud groan, streaking the interior leather with white hot
stripes of his seed. He moaned filthily as he continued to fuck himself through
the orgasm, drawing more and more pleasure until it was almost painful from
oversensitivity. The dildo gave way from his ass with little resistance and was
shiny when brought up to his view from the mix of lube and his own fluids. He
placed it gently back in the box, salivating at the thought of using on the
hood of the car next time. Dean licked the come off the seat, flicking his
tongue into the crevices of of the dented upholstery just like he knew baby
like.
 
He pulled away reluctantly to replace his discarded clothing, purring at the
almost pristine look to the car after how he'd just pleased himself. Dean sat
blissed out in the driver's seat, running his hands lovingly over the covering
on the steering wheel. After a briefly period spent in post-coital relaxing,
Dean pulled the keys from the ignition to return his baby back to her slumber
after a hard night out.
