Okay, I've read so many of these it's ridiculous. So I've decided to write instead of read, I've never done one of these before – tell me how I go! I'm going to do one for each of my favourite pairings. Starting off with Sirius Black and Harry Potter. Also, in no. 28, the middle name is Arcturus instead of Orion to show that it's not our Sirius, but the alternate one.

1. Comfort

As a child, Harry never felt any form of comfort, with Sirius, he never went a moment without.

2. Kiss

Harry doesn't really count his first kiss with Cho as his first kiss, because his second kiss (his first with Sirius) was so much better, even though Harry had slammed his mouth too hard against Sirius', squished their noses together in an awkward way and then ran off completely mortified and blushing so hard he could've moonlighted as a Weasley – or the sun.

3. Soft

Sirius was so unaccustomed to things being soft, after almost thirteen hellish years in a prison made of hard stone and misery, that he spent a good ten minutes just running his calloused hands over Harrys soft palms.

4. Pain

Sirius felt his heart breaking, slowly and quickly at the same time, crushing painfully, at the sight of a nervous Ginny Weasley pressing her lips to Harrys in the empty kitchen.

5. Potatoes

Harry (still) couldn't stop giggling the time (the one time) Sirius had slipped on a slippery slice of potato on the floor and had ended up sprawled all over the floor and (somehow – Sirius blamed Kreacher) covered in more potato.

6. Rain

Harry generally didn't like the rain, it brought memories of being locked out and having to huddle for warmth and tears and pain and dementors, but seeing Sirius step through the front door, white shirt see through and sticking to his chest, Harry decided that everything needed exceptions.

7. Chocolate

Remus had a stash of chocolates, very carefully hidden, but that didn't stop Sirius from finding them, melting them down, and taking the time to smear it all over Harry before spending the rest of the night cleaning it off with his tongue.

8. Happiness

Waking up, rolling over, and seeing his eyes already open and sparkling with love.

9. Telephone

Sometimes Harry regretting introducing Sirius to the muggle machine (he even took the time to reinforce the idea that it was not at fellytone) but then he'd get a call while he's at work and he only hits Sirius once when he gets home, because he doesn't actually mind the fact that Sirius talks dirty to him over the phone.

10. Ears

Sirius had several piercings in his ears, and Harry loved to tug on them slightly with his teeth or just watch the sunlight reflect off the metal.

11. Name

"Mr. Black and Mr…Black?"

12. Sensual

Sirius would never forget Harrys first attempt at secuding him – hands running all over his body, massaging oils, that absolutely fuckable mouth wrapping around h- Remus opening the door (no one was supposed to be home, Sirius hadn't bothered to lock the door) and everyone freezing for half a second before all hell broke loose.

13. Death

Is not what the Veil lead to – an alternate universe where Sirius hadn't been sent to Azkaban – but Sirius wouldn't have cared regardless because Harry had followed him through – which was a bloody stupid thing to do, you could have died you bloody stupid, impulsive boy who I could not love more.

14. Sex

Harry was impatient (so impatient, he wanted Sirius so badly, he'd tried everything to coerce him) but the man was adamant that he not have sex with Harry until the boy was of legal age.

15. Touch

Of course, that didn't mean that they were completely celibate, oh no – they just didn't go all the way (but Sirius knew how to pleasure Harry without penetration anyway, and Harry was very enthusiastic).

16. Weakness

They'd tried to keep Sirius and Harry apart once Remus had walked in on them, but no one had thought to check for structural weaknesses in the wall that separated their rooms, and no one questioned why Harry moved his wardrobe.

17. Tears

Harry didn't shed a single tear when Sirius fell through the veil, because he had a plan, but he cried his poor little heart out when he found Sirius again.

18. Speed

Nothing could match the speed of Harrys Lightning Bolt – except for Harrys heart when he was near the man he loved.

19. Wind

Watching the wind whip Sirius' long hair about was one of Harrys favourite things in the world.

20. Freedom

On the other side of the Veil it was not the freedom from being a criminal that made it so wonderful, but the freedom to be with Harry.

21. Life

"Harry, don't waste your love on me, you could have anyone you wanted-" "Shut up and kiss me, you old bat."

22. Jealousy

Before the Veil it was Ginny Weasley, and Cho Chang, and almost the entire Wizarding World, through the Veil it was his alternate self, which was so much worse.

23. Hands

Harry loved Sirius' hands, they were so talented and so very good at making him so utterly incoherent and beyond words that all he could say (or think) was Sirius.

24. Taste

Sirius hated cinnamon, he always had – Harry loved it because, for some reason, that was what Sirius smelt most like.

25. Devotion

It was not temporary insanity that drove Harry to take a flying leap towards death, it was his devotion to Sirius that enabled him to swan dive through the Veil with a smile on his face.

26. Forever

Really, Nicholas Flamel should have had better security on that bloody stone of his – but seven hundred and twenty six years later, Harry wasn't complaining.

27. Blood

Harry had only ever had sex with one other person – Sirius, the alternate Sirius – he was tipped off by the different mannerisms and the fact that this Sirius felt the overwhelming need the make Harry bleed.

28. Sickness

"You're fucking sick you deranged psychopath – if you ever come near my Harry again, I will kill you Sirius Arcturus Black!"

29. Melody

They never had children (though they had a hell of a lot of fun trying to break the laws of reality) but they had a 'pathetic song bird' who could belt out a pretty melody.

30. Star

They did adopt a few children, though, and Sirius was adamant about not naming any after stars – their second adoptee was five when they took him in, and his name was Aries.

31. Home

Is where your heart is (so snoring his bloody head of, completely unaware that Harry was making him breakfast in bed).

32. Confusion

James Potter didn't know what to think of the pair that had moved in next door, he didn't care about the age difference, or that they were both blokes, but the fact that they looked so much like Sirius and, well, him, always left him slightly sad (is that what they would have looked life, so happy and carefree, if he'd not decided to pursue Lily?) and definitely confused – it was like they were twins or clones or something.

33. Fear

Harry was not scared of spiders, but he let Sirius pretend to be his knight in shining armour and 'rescue' him from the terrifying, hideous, absolutely giant Daddy Long Legs.

34. Lightning/Thunder

Normally they had to silence their room, because they both got a bit loud and carried away, but when it stormed the thunder stoped any sounds from disturbing their neighbours.

35. Bonds

After the disaster with the Other Sirius, Harrys Sirius decided to show him how sex like that supposed to work – and Harry wasn't hurt at all.

36. Market

Midnight Moonlight Markets were a specialty of Godrics Hollow, and they always went and Sirius bought silly Muggle trinkets that served no purpose but to make Harry laugh.

37. Technology

Sirius only ever worked out the phone – so he could have one sided phone sex with Harry while he was at work – and the video recorder – what he used that for, however, is for he and Harry to know.

38. Gift

Every morning when Harry had to leave for work early and Sirius was still asleep, he left a note on his pillow for Sirius, declaring his love of Sirius and all the naughty things he planned on doing to the older man – Sirius kept them all in a safe box, and looked at them often.

39. Smile

Large, happy and with missing teeth, the small little Harry Potter next door made Sirius mourn for his own Harrys ruined childhood.

40. Innocence

Sirius took Harrys, quite happily, when Harry turned sixteen – Harry had finally convinced him that the Muggle legal age was good enough and, watching that devious little minx undress and beg to be fucked – who was Sirius do deny him?

41. Completion

It never meant anything sexual to Harry, because he could feel complete lying on the grass in their backyard, watching clouds, with Sirius.

42. Clouds

Sirius was the one who pointed out the rabbits and boats, Harry pointed out the dragons and penises.

43. Sky

They were being risky, and had been in a public muggle park under the night sky, when they were spotted – in the rush to get away before the cop tried to arrest them, Harry left his underwear and Sirius left his underwear, shoes, shirt and pants, but remembered his socks.

44. Heaven

Harry didn't care that the Dursleys raised him instead of Sirius (though he did care that Sirius spent that time in prison), because his life with Sirius made up for his lacking childhood – this was the heaven he dreamt of whilst in a cupboard, under the stairs.

45. Hell

Waiting the final five minutes until Harry got home from work – the bloody clock had it out for him, and went slower.

46. Sun

Harry got along with his alternate mother like a house on fire – Sirius got along with this worlds James like the sun crashing into the Earth.

47. Moon

"Pull your pants back up Sirius, your feud with James Potter does not have to be that childish – I don't care if he's doing the same thing!"

48. Waves

Watching Snuffles jump in and out of waves on a deserted beach was fun – watching a naked Sirius emerge from the ocean was even better.

49. Hair

Sirius got bored and cut his hair short one day – Harry told Sirius he could sleep outside until it grew back.

50. Supernova

Eventually there is another war, and another, and another, and eventually the world is destroyed, but the explosions are nothing compared to the love of a pair of wizards, long passed into the next life.
