Here it is. Sirius' first fantasy about Remus. It's just a short one but, after all, it's the first! And might not be the last.
Someone ideas what their next time could be like?
I have a few ideas but it's hard to let go of a story line and just.. let them do it. But I will, promise!

I do hope being silent for so long did not make me lose my followers. If so, please come back! I promise you a lot of dirty horniness.
Seeing I promised to write all 50 of them, I will.

'You have no shame, do you?' Remus was amazed by the lack of shame his boyfriend possessed. It was a true gift, really.
That was what made it hard to prank him. You had to really, really touch him in his pride, or he would not care.
James hexed him to sound like a donkey once. He was a fucking fantastic donkey. He was even forced to walk around in a skirt and he so he did, fabulously.
So it usually ended in doing something stupid with his hair. Weasley hair was the worst punishment. The fiery red locks did not sure him.

'Shame? Why shame?' Sirius shouted. 'Trust me, it's a lot more innocent than pretty much everything we've done today. But alright, if you don't want to know what I was like as a horny, thirteen year old teenager, your loss.'
'Thirteen?' Remus exclaimed. 'You were just a child!'
'And quite an innocent one at that. I was!' Sirius added quickly when Remus snorted.
'Dearest, there's a lot you are, but I doubt you were ever innocent.'
'Fine. Just.. a bit more innocent, then. And never call me dearest again. It makes me feel like I just shagged my gran.' Sirius made a face and so did Remus. H
e had met Sirius' grandmother once in Hogsmead and no, not the kind of granny you'd want to shag. If, you know, you were into that kind of thing.

'So, do you want to hear this or not?' The animagus complained, getting impatient and in need of attention.
After all, you did not get to show your lover how you jerk off to them every day!
'Yes. Fine. Tell me about your first sex fantasy at the age of thirteen.'
'No, no! It was not my first. Not at all. But it was the first about you.'
'Just tell me that one.' Now Remus was getting inpatient. He felt awkward enough about this as it was.
If he could just adopt some of that shameless character.

'Actually. Why tell if one can show!' He made that ridiculous focus face again and, out of thin air, a stone bowl appeared,
inscripted with a language Remus was not familiar with. He did know, however, what the object was. He had read about it in several books.
It was a pensive.
The bowl was used to keep memories stored you'd either rather forget or never forget. There was no doubt what Sirius was up to.
And he was not comfortable with this idea.
'Sirius. No. You can't expect me to watch whatever thirteen year old us are doing in your perverted memory. That is so.. inappropriate!'
'It's not that bad. I promise. Despite my rogue exterior, I was quite the frustrated teenager. Trust me, you'll enjoy this.'
Without further discussion he pulled Remus by his arms, the latter tried to struggle but failed, and they fell down a long hole,
landing on a mattress between thick drapes they were both familiar with.

Sirius Black is lying in bed. It is night. It is dark. The three other boys are vast asleep and cannot hear the words he is mumbling while his hand strokes his hard, teenage cock. His eyes are closed, his chest heaving up and down as he breaths deeply with every move his hand makes.

For a second Remus is distracted by the sight, forgetting he does not was to be here. It is beautiful, in some weird way. Kind of enchanting..
Soon enough though, he realizes he is way closer than he want to be. This is ridiculously awkward.
He stares up, hoping to find some portal back to the real world but is greeted by the sight of nothing more than a four-poster bed.

'Not escaping til it's done, sweetums.' Sirius chimes.
'Does it not bother you to see yourself jerking off like that?' Remus protests as he pulls his legs up and wraps his arms around them.
Awkward, awkward, awkward.
'Hell no. I am gorgeous. It's the best porn in the world.'
Remus rolls his eyes and shakes his head at the wicked grin he faces.
'You are insane.'
'What else is new. Will you just shut up and watch how I remember this?'
'Fine.'

Out of nowhere, a form materializes on top of Sirius. A beautiful girl with thick, blonde hair and big breasts.
It is now her hand that moves in sync with Sirius' as he jerks of in a slow, steady pace.
Within two seconds the girl changes shape. She is now the skinny, black-haired Ravenclaw they met in Potions last year. She giggles and sighs as her hips buck.
She is naked. But Sirius just whispers. 'No. No, no.' And again, she changes. A blonde girl with braces. A strawberryblonde Hufflepuff.
A brown-haired Slytherin Sirius fought with the other day. 'No. No.' A brunette from a muggle magazine. A witch from a local band with a flaming tattoo on her back.
Lily.
'No! Fuck!' Sirius close to shouts as he lets go of his erection and repeatedly plunged his head against his pillow.
'Fuck! Fuck. Fuck. Fuck.' He shouts again as he pants heavily and stares at the thick cloth of his four-poster bed.
'Please, not this.' He whispers.

Remus is taken aback by the look in the young boy's eyes. Crawling up to the head of the bed he leans over the naked boy's face.
The grey eyes, so full of emotions, stare right through him. He can't remember ever seeing Sirius like this.
'You look so devastated.' He whispered but Sirius pulls him back to where they landed.
'Just look.' The black-haired boy demands. So Remus does.

The young boy, so beautiful with his thick, black curls and fierce grey eyes, rubs his face with his hands and then rushes them through his hair.
He sighs. He shakes his head slowly as he closes his eyes again. Thirteen year old Sirius takes a deep breath as he opens his eyes once more and looks to his right.
There is nothing to be seen but red velvet drapes. But he knows what's behind them. Just a few feet away from him in a four-poster bed so similar to his own.
When he closes his eyes and lets his hand slide down to his cock, uncertain this time, another form materializes in the bed.
This time not on top of him. Not naked and nothing with big boobs and long hair.
It is a boy. A young, slender boy in a brown jumper, wearing his Gryffindor tie and brown slacks.

'This is so weird.' Remus mumbles, but he can't deny he is flattered by this, as Sirius promised, rather sweet display of realization.
Still, it is weird to see himself, a child of merely thirteen years old, lying there. If he had known that at the time..
His thoughts were quickly abandonded as something magical, no shit Sherlock, happened.
Something breathtaking and so beautiful it would make Remus admire Pensieves for the rest of his life.

The boy, Remus Lupin, slides his imaginary hand down Sirius' chest, his stomach, and forms around the erection, pumping up and down in the same rhythm Sirius does.
He is nothing but a fantasy, after all. But such a lovely one. Yet, he is no longer alone.
As the Sirius in the bed closes his eyes and surrenders his unwilling mind to the fantasy, it is as if he comes loose from his material body and becomes a ghost.
Not the silvery kind of ghost. A fantasy kind. A perfect reflection of the boy in the bed and only ever so slightly see-through.
He sits down on his knees and pulls Remus with him.
The fantasy hand lets go of the hard cock while real-Sirius still pumps on.

On his lap, though he can't feel their weight, the fantasy between himself and his roommate evolves.
A beautiful play of interaction, of emotions. Sirius nuzzles Remus' neck, softly placing kisses.
Remus lets his head rest back in a way he never does in real life. It is just a fantasy after all.
His skinny, pale hands roam over Sirius' fantasy chest as Sirius slowly undresses the other boy.
He does not refuse or stutter or try to hide his scars. He is just a fantasy as well, after all. And this Remus bears no scars.
Sirius never had enough time to look at the boy naked, at that stage. So there are no scars. He is not nearly as skinny as he truly was.
He is soft, unblemished and perfect. A perfect fantasy.

They lean towards each other, softly kissing is soft pecks as Sirius lets his hands wander over the pale chest and back, rushing his fingers through silken, honey blonde hair.
'You are beautiful.' Fantasy Sirius whispers.
'So are you.' Fantasy Remus whispers as he leans down towards his naked lover and forms his hand around the erection, as hard as a rock by now. 'So are you.'

Sirius pumps faster and harder and the fantasy does the same. It places kisses in Sirius' neck, whispering words no one can hear or understand.
'Remus.' Sirius mumbles as he arches his hips, his abdomen contracting. 'Oh Remus. Yes. No. Yes.'
He growls as the name one last time emerges from his plump lips and he comes in thick, pearly strands.
The moment he realizes he has come he lets go of his cock as if it burns him and fantasy-Remus disappears, along with his reflection.
Sirius pants and his eyes are wide. Not from the orgasm but from the surprise of what made him come. His hands are still in the air, a silent surrender.
'Fuck.' He whispers once more as he crashes his hands down in the blanket. 'This is not good.'
He slams open the curtains and walks towards the bathroom, a soft voice stopping him in his walk.

'Sirius? Are you alright, is something wrong?'
His hands clench to fists as he refuses to look around. Looking at the source of that voice right now would be too much.
He feels.. dirty. And not in a good way.
'Taking a piss.' He mumbles as he locks the bathroom door behind him. But taking a piss was the last thing on his mind now.
Turning on the hot shower Sirius slides down against the wall, water tickling against his hot, frustrated skin.
Streaking wet hair from his face, he rests his head against the cold tiles.
In between frustrated frowns, a quick and almost unrecognizable smile twitches as the boy realizes that he might he in love.
Then his face falls to a frown again as he realizes. He is in love.

Remus' lips tug in a halfhearted smile as he realizes his remembers this moment and Sirius' gruff response.
A shower being turned on in the middle of the night and he was too insecure to ask.
He wished he could stay there. See how Sirius got through the night. He didn't get the chance, though.

A strong force pulls Remus from the bathroom and Sirius with him. Landing on the bed, on top of the thick blankets, Remus stares at Sirius.
'That was so weird. 'He sighs.'Don't ever do that to me again!' Remus reprimands him but to this surprise he
now finds a slightly puzzled look at his lover's face.
'It was weird.' One eyebrow raised makes him look like a silly cartoon, wondering where his plan went wrong.
'Not the masturbating part, though. That was awesome. But how I pictured you. So.. unlike you.'
But Sirius wouldn't be Sirius if he was serious for too long. Soon enough he breaks out in a big grin.
'So. That was the first time. As you can see, I was not too happy about it.'

There was a short silence for Remus could feel Sirius was not done talking yet. He had a nose for that kind of stuff.
It was probably what came with knowing (and loving) someone for so long.
'The next day I dispatched it as a boyish experiment but damn. It was so hard to look at you. I figured out your eyes were not the color they were. That your hands were littered in way more tiny, silver scars I had ever noticed. And not to start on how skinny you truly were. Not to mention how beautiful.'
Sirius crosses his arms and looks at his Remus, pretend angry. 'If someone could explain why I act so sappy around you, that would be great.'

Remus nudged his lover.
'I bring out the worst in you.'
'Please, keep up the good work.'
'Will most definitely do. Thank you for your fantasy. It was a lovely night.'
The slight mockery in his voice did not go by unnoticed but Sirius did not feel like acting on it. He did not want this night to be over.
'This does not have to be over!' See? 'Care to share one of your fantasies?'
'No.'

That night Sirius was once again reminded about how stubborn the bloody werewolf was.
He tried everything, literally everything, to convince his lover to share something cheeky with him but it was no use.
He even did his cute kitten routine. Kitten! While he was clearly a canine creature. No effect whatsover.
So eventually, after quite some time, they crawled up in the warm bed and fell asleep.

And no, there won't be a sexual fantasy of Remus anytime soon though I do have one planned around the Prisoner of Azkaban. In the meantime, keep up the ideas, I'll keep up working on sexy time. Doubting whether the next one should take place in the Greenhouse, Hagrid's hut or Zonko's basement. Zonko's would be an amazing Valentinesday gift though.. don't you think?
