Summary
     He looks young though. Twelve, maybe. Thirteen? He reeks of daddy
     issues and neglect. Sebastian takes him home when he doesn’t even
     bother with any of his sweet little pick up lines, just stands on his
     toes and wraps his arms around Sebastian’s neck and kisses him. He
     tastes like hunger and mint toothpaste.
He waits on the corner, licking his lips, sucking on a cigarette like the smoke
is better for him than oxygen, throwing himself at every lonely man who passes.
“I’ll give you a good time, please take me home,” he moans. “Please, it won’t
cost you anything, I’m just looking for a good time.
He looks young though. Twelve, maybe. Thirteen? He reeks of daddy issues and
neglect. Sebastian takes him home when he doesn’t even bother with any of his
sweet little pick up lines, just stands on his toes and wraps his arms around
Sebastian’s neck and kisses him. He tastes like hunger and mint toothpaste.
He huffs out that his name is Jim on the walk home, in between making out
against a wall, the little boy practically having to climb Sebastian to get to
his mouth. Eventually Sebastian just carries him, lets Jim suck at his neck
until they get to Sebastian’s dingy flat.
They do not make love, they fuck, hard and guttural with screams from Jim that
would surely wake the old woman living above him but Sebastian doesn’t care
because the way Jim’s small hips move turn him on more than anything he’s seen
before.
They lay together afterwards, Sebastian holding Jim close mostly because Jim
wad wormed himself as close to the man’s skin as possible, almost trying to
bury himself underneath. His eyes look dead.
"Bruises," Sebastian says. Jim squints. "Where’d you get them?"
His chocolate eyes close and he lets out a long breath. “Fucking you,” he says
but the bruises are on his stomach and sides and Sebastian hasn’t touched
there.
"Really?"
Jim opened his eyes. “None of your business,” he says instead and Sebastian
figures out then that the bruises are the reason Jim is in his bed so he
doesn’t say anything else, just silently offers Jim a cigarette and hold him
when he tries to dig into Sebastian’s skin again.

Sebastian looks for him after that. He doesn’t know why but he thinks about the
little boy who must hurt so badly all the time. He’d been beaten as a kid too.
The only difference between them is that Sebastian fucked any woman he could
get into bed with him rather than older men.
He sees the dark haired boy again a month later, standing on his same corner,
tears dripping down his face as he spewed pick up lines like prayers, begging
for someone to take him home. 
When his eyes spot Sebastian he runs over and kisses him again, just like he
had before but it’s wet this time, not as skilled. It’s needy and desperate,
kissing like it’s CPR and Sebastian indulges. 
They don’t even make it back to Sebastian’s flat before his cock is out. Jim
starts to sob, ignoring his tears and moving with still hands, pushing
Sebastian against a brick wall halfway down an alley and dropping to his knees,
opening Sebastian’s trousers and sucking his cock into his mouth to silence
himself. To Sebastian it feels wonderful, Jim screams as he moves his lips up
and down Sebastian’s cock and it sounds strange, the muffled squeal but the way
his throat tenses up and the sounds feels like heaven against Sebastian’s skin.
When he comes it’s quiet and unexpected and he almost tears clumps of hair out
of Jim’s scalp. 
The little boy’s thin lips work his shaft through the orgasm and when it hurts
more than feels good he pulls him away with a small ‘pop’ and collapses
forward, leaning his head against Sebastian’s thigh.
"We’re almost back to me flat, y’know," Sebastian said.
"I don’t want your sympathy," Jim spat and stood. 
"I’m not offering sympathy. I’m offering safety."
"I don’t need your help," Jim shrieks, his voice breaking. He coughs. "I don’t
need anyone."
"Can I have your number?"
"No."
"Do you want mine?"
"No."
Sebastian reached into his pocket, he always kept a pen with him. He takes
Jim’s arm and tears it forward, writing his number on Jim’s palm in sharpie.
"Cell phone. You can text if you want," Sebastian says and Jim stares at his
hand like Sebastian had just carved runes into his skin.
Tears started dripping again, dirty water from a broken faucet and he turns and
runs, down the street, the bottom of his shoes tapping against the pavement.
Sebastian sighs and leans back against the brick wall, thinking about following
but deciding not to. It’s not his battle, not his baby to save.
—-
A month passes and Sebastian doesn’t forget about his little boy.
'Why did you give me your number?'
He thinks it’s the girl he’d fucked last night at first and replies, ‘Because
you’re beautiful, love.’
'I'm not. I'm Jim. Do you even remember me?'
Sebastian smokes his cigarette down to the filter before replying.
'Think about you all the time.'
There is a very long pause before his phone lights up back again. Sebastian
doesn’t light another cigarette, he settles on his hard couch and closes his
eyes.
'Why?'
'I don't know.'
His phone doesn’t buzz for the rest of the afternoon. Sebastian sleeps.
—-
Jim texts him a few days later, Sebastian can’t tell how many, days have faded
together into one long string of hopeless attempts to feel something.
'I'm going out to night but I want someone to stop me.'
'Why?'
'I hate myself. I don't like fucking strange men I just need to know I'm
alive.'
'You can come to my place. Do you remember where it is?'
'Yeah. I'll be there later. I don't know when.'
—-
Sebastian cleans the place up a bit, gathering all the empty beer bottles and
empty packs of cigarettes and throwing them in a garbage bag. He shoves that in
the bins outside and then he waits, giving up on making things look too neat.
Jim would understand.
The boy shows up on his doorstep near midnight, shaking even though the air
isn’t too chilly and he’s wrapped in a jumper at least two sizes too big. He
looks at Sebastian with sad eyes that makes Sebastian think of looking into the
sky and thinking about how far away the stars are.
"Can I come in?" he asks and his voice is still despite the way his body moves.
"Please?"
Sebastian steps aside and Jim takes cautious steps in, looking into the dark
room as if there were bear traps on the floor and a gun set to shoot anything
that moves hanging on the wall.
"Are you going to rape me?" Jim asked feebly, sitting down on the couch. He
kicked his shoes off and curled into himself, hiding.
"Nope. No sex unless you want it," Sebastian replied, sitting and giving Jim
his room. 
"Are you sure? I’d rather be prepared for it," Jim mumbled. 
"How old are you?" Sebastian asked and Jim flinched.
"T-twelve."
"Really?"
"Fifteen."
"You sure?"
"I’m fifteen," Jim said again. "Men like it when I’m younger I j-just shave so
it looks like I haven’t hit puberty yet a-and I look like a kid." Jim makes a
face and it’s obvious he regrets the words. Sebastian doesn’t feel as bad about
sleeping with him now.
They don’t talk. Sebastian turns on the telly and Jim falls asleep in a little
ball on the couch. Near four Sebastian moves to his room after grabbing a spare
blanket from the closet and draping it over Jim.
—-
They text for hours each day and Jim tells Sebastian in messages less than 130
characters about his dad and how many times he’s tried to kill himself so far.
At least once a week Jim comes and sleeps on his couch, when his head gets to
be too much for him to stand or when his dad hits him too hard.
On one rainy night Sebastian drives Jim to the hospital to fix a broken wrist.
They do not talk.
Sebastian has so much to say to the little boy, he’s grown so much in the past
year but he’s still Sebastian’s. 
They don’t shag again until Jim arrives at Sebastian’s door and quietly mumbles
that he’s sixteen now. The don’t fuck like they did before, they make love on
the couch and everything tumbles out, then.
"Stay with me," Sebastian insisted. "Please, stay.  I don’t want you going back
to your dad, I love you. I want you safe."
Jim stays quiet.
"Okay," he says. "I’ll get my things from home. I d-don’t…"
Tears drip down his face and it’s the second time Sebastian has seen him cry.
He wonders idly what’s happening in Jim’s brilliant mind.
"I’m scared," he breathes, voice feather light in the darkness. "I d-don’t want
to leave. He’ll notice."
"He won’t," Sebastian promised. "Even if he does I’ll make sure he won’t hurt
you."
Jim wiped his tears on the back of his hand and stared at the ceiling.
"You look dead," Sebastian says.
"I feel dead."
"I want to make it better."
"You can’t."
"I can try."
No time passes before Jim pushed Sebastian off of him and pulls his trousers
up.
"You only like me because I’m young," Jim snapped. "Because I’ll fuck you."
"Jim-"
"I’m sorry I let you touch me, I’m sorry. Just forget about me, please I need
to go h-"
"Jim!"
Sebastian’s voices shakes Jim’s bones and Sebastian takes a breath, trying to
calm the anger shaking his stomach. 
"Listen to me," Sebastian said. "Listen. I have been comforting and talking to
you for far too long for me to just want your body. You’re so smart, so
amazing. Listening to you talk is like… It’s like…" Sebastian stops and shakes
his head. "It’s wonderful."
Jim’s shoulders slump. He sits back on the couch.
"You’re better than stars," he says quietly and tucks himself into a neat
little ball. "Can I be alone? I’ll go get my stuff tomorrow."
Sebastian swallows hard, feeling his mouth go dry and hearing his heart beat
steadily along, loud in his ears.
"That’s okay. Talk to you in the morning. Good night."
"Good night, Sebastian."
Sebastian leaves his little boy alone, darkness eating up his skin and he
pretends he hears Jim say ‘I love you’ as he closes the door to his bedroom.
