Summary
     It starts as a game, a marriage between friends. Bucky takes it too
     far, and Steve lets him.
Notes
     For Bonnie, whose patience and capacity to love never fail to amaze
     me.
The rain fell in sheets outside, oppressive and unrelenting. Bucky sat with his
head on his arms, bored beyond belief. Steve seemed unaffected, scratching away
at his sketchbook as he so often did.
Bucky turned away from the window. “Let’s do something,” he said.
“Like what?” Steve didn’t look up from whatever he was preoccupied in
capturing.
Barred from their usual outside activities (Bucky had sworn to Steve’s mom that
he’d look after his friend, which included keeping him in from the rain and
consequently pneumonia) he thought back to the games his sisters would play.
“We could play house,” he said with a shrug.
That got Steve to look up at him with a twist to his mouth. “Really Buck? You
know boys don’t play that game.”
Bucky scooted closer to Steve and grabbed his foot. “C’mon, what else’re we
gonna do? ‘Sides, I’ll even be the girl so you don’t have to.”
Steve shook his foot from Bucky’s hold and rolled his eyes. Bucky grinned,
sensing his victory.
“C’mere,” he said and pulled Steve to his feet. The other boy went without
complaint. “First what we gotta do is get married, cause we can’t have a house
unless we do that first.”
“But we need someone else to marry us,” Steve pointed out. Bucky was already
rushing to get his supplies. First he (carefully) grabbed the Bible Steve’s mom
kept in her bedside drawer, dropping that off before he opened the door to the
apartment’s stoop and picked a handful of dandelions from the pot of half-dead
flowers.
Steve lifted his eyebrow but otherwise didn’t comment on Bucky’s antics. Once
he had gathered his supplies, Bucky stopped in front of Steve and gave him a
breathless smile.
“Okay, this is easy. I’ll walk you through it.” He held the weeds to his chest
with both hands, mimicking his idea of the posture of a bride. “Usually Becca
does this part, so just pretend she’s here. She’ll say your full name; she’ll
say it like Steven Grant Rogers.” Here his voice took on a solemn tone. “Oh
wait, first she’s gotta say ‘We are gathered here today to witness the union of
these two people under God.’”
Steve fidgeted, unsure of what to do with his hands. He whispered, “What’s the
Bible for?”
“For being official, now don’t interrupt.” Bucky resituated himself into his
pose, staring straight at Steve. “Now, Steven Grant Rogers, do you take this
woman to be your lawfully wedded wife?”
Steve paused, a layer of sweat broke out on the back of his neck. “Buck, you’re
not a girl.”
“I know, just pretend.” Bucky put his hand to his hip. “C’mon Steve, this is
the easiest part. You know what you gotta say.”
Steve sighed. “I do,” he said.
Bucky smiled and took one of Steve’s hands. When he played with Anne, she said
that it was very important for them to not forget this step.
“And do you, James Buchanan Barnes, take Steven Grant Rogers as your lawfully
wedded husband?” He continued, giving himself a pause before he answered, “I
do.”
Steve’s entire face was flushed at this point, and Bucky could feel his palm
was slick where it was pressed up against his.
“I pronounce you Man and Wife. You may now kiss your bride.” Even at thirteen
Bucky was already taller than Steve, but he tilted his face up anyway and
leaned forward to compensate.
“Can’t we skip this part?” Steve croaked.
Bucky frowned. “It’s not real unless we kiss, Steve. Here, I’ll close my eyes.”
He did, and Steve stared at him like he was an alien species. Still, they did
all their steps correctly, even got out their Bible to make it official. He
figured it probably wasn’t so bad since they were only just pretending. Steve
leaned in and touched his lips to Bucky’s lightly, just a brush and then it was
over. Somehow it was different from kissing his mom, more firm and moist. He
licked his lips and was dazed by the smile Bucky was giving him, golden like
they really had just been married and he couldn’t be any more thrilled about
it.
Steve gave a shy smile back, happy that he could please his friend.
                                       …
Since Steve’s mom was working the night shift, they had already prearranged
with Bucky’s mom for him to stay over. They made and ate dinner under the guise
of being married, Bucky taking care to fuss over preparing Steve’s food until
he pushed Bucky. They wrestled until Steve started wheezing, then he didn’t put
up a fight when Bucky wanted to feed him.
As they climbed into their marriage (Steve’s) bed for the night, Bucky took his
customary spot on the edge and Steve put his back to the wall to make room for
him. They’ve been doing this for years, but tonight it felt different. Their
space felt forced, but when they pressed together they were much too close.
They faced each other in the dark, and as soon as Bucky opened his mouth Steve
knew he was doomed.
“Steve.”
“Yeah Buck?”
“We’re still playing the game, right?”
“Yeah.”
“Okay, then you should kiss me some more.”
Steve wasn’t as hesitant as the first time, but he still paused to take in
Bucky’s eyes, shining in the dark. He didn’t close them this time, but Steve
leaned in anyway. He pressed his mouth to Bucky’s, hesitant in his exploration.
Bucky kissed him back, only sure that a real kiss needed constant pressure. He
slipped his hand under Steve’s shirt and was met with the sharp ridges of his
ribs. Steve pulled back, startled at the touch.
“Um, if we’re married, then we both need to be naked.” Bucky ducked his head,
but he wasn’t ever anything less than sure of himself. Steve felt as warm as if
he were running a fever, and even as his hands shook, he still managed to pull
his shirt over his head. Bucky did the same, then pushed down his underwear.
Steve didn’t pull down his until Bucky was able to look him in the eyes again.
They got under Steve’s blanket, wordless in the knowledge of the severity of
what they were doing.
Steve flinched when Bucky’s hand touched his shaft, but this time Bucky
wouldn’t look away. Steve took courage from that and pushed his hips farther
into Bucky’s touch. He wrapped his fingers around the soft length of flesh and
began to stroke up with his wrist. Steve’s groan was high pitched. He shivered
and pushed his face into Bucky’s shoulder, the feeling similar to when he
touched himself, yet so different and warm knowing it was Bucky, his best
friend that was touching him.
Bucky rolled so that he was laying on his back, nudging Steve so that he was
laying on top of him. He was breathing fast, his prick stiff from where it
pressed against Bucky’s stomach.
“You gotta go nice and slow with me like I was a dame, Stevie.” Bucky’s voice
was pitched low and Steve didn’t think he was ever gonna stop blushing.
“But how do I…”
“Here, I’ll help ya.” Bucky pushed his knees up and guided Steve’s prick until
the tip was pressed flush against his hole. Steve couldn’t stop trembling,
which stood in contrast from how calm Bucky was being about their whole
endeavor. He gripped the back of Steve’s waist and smiled up at him, pulled a
little bit to let Steve know it was okay to keep going.
He did. He pushed forward until his tip was inside and Bucky’s face was all
scrunched up like he was getting shot.
“Ow, wait.” Bucky pulled away and got out of bed, heading towards the bathroom.
“Where’s your mom keep her hand cream?”
“Uh, medicine cabinet. Why?”
Bucky rummaged until he found the bottle, returned to Steve and handed it to
him. “You know how it feels better with this stuff? You should put that in me.”
Steve was sputtering and breathless, but Bucky just laid back as he had before,
legs spread and expression expectant. Steve ducked his head and poured a dollop
onto his fingers, red all over from the way Bucky was displaying his privates
to him. In a way, this made it seem that what they were doing was that much
more special. Steve took his slicked up fingers and pressed them to the pink
rim of Bucky’s hole. Bucky watched him with his lip between his teeth as those
long fingers pushed the lotion inside, the sensation making his own prick
stiffen against his stomach. He groaned quietly and pushed his thighs further
apart.
Steve was rapt with attention to his task, his brow drawn into a furrow as he
stared down at his hand, fingers making a gentle pushing motion in, and then
curling into the soft flesh of Bucky’s insides. He didn’t stop until Bucky was
squirming and panting from his touch, his cock throbbing with a sudden need he
hadn’t felt before.
“I’m gonna put it in now, okay Buck?”
Bucky just nodded and pulled Steve onto him by his shoulders. He kept tugging
until Steve’s face met his, and it was a little painful from where their noses
and teeth bumped, but it felt right to be so close to each other.
This time when Steve pushed he went in easy, and Bucky didn’t groan from pain.
He was surprised at how Bucky’s insides grabbed at him, clenching and pulling
him deeper. Steve’s arms shook from where they were holding him up. He was
running on instinct now, pulling out and then being sucked back in from where
he pushed closer. Bucky was sweating beneath him, his hair stuck to his
forehead but he looked so good like that. When his arms gave out Steve
collapsed onto Bucky’s chest, wheezing from the effort.
Bucky broke out of his haze. “Steve? Are you, wait, here.” He shifted again,
this time rolling Steve under him until Bucky was the one sitting up, Steve
reclining on his back. He looked up at Bucky with something like wonder in his
eyes, but it fell closer to trust and a willingness to do anything for his
friend.
Bucky knelt with his thighs straddling both sides of Steve’s waist. Flushed and
panting, he took Steve’s prick in his hand and then carefully lowered himself
onto it. They both groaned at the soft give of Bucky’s body. He didn’t know how
to move at first, raising and lowering himself with just his legs, then rocking
back and forth when that proved awkward. He settled for a combination of the
two, circling his hips and gasping at every wave of sensation that sent him
clenching and shivering from where Steve was inside him.
Steve was frantic beneath him, clenching his fingers into Bucky’s legs and
squirming to thrust. He arched and drove his cock faster into Bucky, a small
groan and the slapping of skin the only sound he made as he came. Bucky felt a
gush of wetness inside him that made his eyes widen. He fought to control his
breathing and eased himself off Steve when he had stilled, then laid down next
to him.
Steve blinked and came back to awareness of his surroundings, saw Bucky’s face
and gave a shy smile. Bucky just laughed and hugged him. Steve settled into his
embrace, then realized Bucky still hadn’t come when he felt a hardness against
his leg. He reached down without thinking and tugged on Bucky’s cock. Steve had
him whining and wiggling for more before long. He grunted and pressed Bucky to
him to keep him still, then sped up his pulling in the way he did to make
himself come when he knew he was close.
Bucky stopped moving, and just when Steve thought he’d have to try something
else a thick white stream shot from the head of Bucky’s cock, most of it
hitting Steve on the chest.
Steve held his breath and looked down at his own softening erection. “Um,
Bucky? I love you.”
“Yeah?” He looked up to see Bucky smiling at him, all gentle like he was proud
of Steve. “Love you too punk. Now get me a rag so we can clean this mess up.”
