The Kiss Chronicles Chapter 1: Spine, a mortal instruments fanfic

Hey so I know I've already posted this on tumblr but I figured that I would post it here too.

This will just be a bunch of oneshots having to do with Malec and different kisses that they share. I'm not sure how often I'll be able to post but I'll make sure to post chapters as soon as they get written.

I hope you enjoy this one it's the spine kiss:

"No wonder your back has been hurting, darling, you have quite the nasty bruise. I wonder where you got that, hmm? And your shoulders are also full of knots." Magnus says while pressing his hands against the (mostly) alabaster plane of his boyfriend's back.

Said boyfriend simply grunts in response and closes his eyes as Magnus continues to massage his back.

Alec wasn't sure whether or not Magnus was using some of his magic but his fingers definitely felt magical against the boy's skin.

His back had been hurting for about a week before Magnus had noticed. It wasn't his fault- Alec had been good at covering it up. He knew that Magnus would worry and insist on healing him and he didn't want to be a burden. But after coming home from a demon hunt at two a.m. for the fourth day in a row, and barely being able to lie down without wincing in pain, Magnus had demanded to know what was wrong. Alec had barely finished speaking before the warlock was snapping his fingers, making his shirt disappear, and gently pushing him onto the mattress to survey the damage.

The damage was a very dark, almost black in color, bruise in the middle of his love's back that made Magnus want to wince himself. How long had Alec managed to hide this from him? How hadn't he seen this earlier? Knowing Alec, the younger boy had probably felt like he needed to bare the pain without any help from others.

There weren't even signs of an iratze.

Magnus shook his head in mild irritation before leaning forward until his lips were just barely brushing up against Alec's left shoulder blade.

"What are you doing?" Alec finally speaks after the long moment of silence.

"Healing you." Magnus answers simply.

"I'm fine, Magnus, really." The shadowhunter begins to squirm under him.

"The look on your face when you tried to get into bed begs to differ, sweetheart, so just hold still and let me do this." Magnus replies before pressing his lips firmly down onto the pale skin.

Alec lets out a small moan when his boyfriend kisses him and the painful pleasure of magic courses through the spot.

He moves to the right shoulder blade resulting in a pretty similar reaction from Alec.

Magnus hovers over the bruise before kissing the dark spot in the center of Alec's back.

Alec bites down on a pillow next to his mouth and his hand claws at the sheets of the bed. Magnus holds onto the boy's hips, locking the shadowhunter in place.

For a while, the pain blazes up, consuming Alec's whole being. All that he can see, hear, taste, smell, and most importantly feel is pain.

Before it suddenly stops.

His whole body sags against the bed. He feels way better now than how he was for weeks.

Magnus places a few more kisses down his spine and this time when he moans it is because of the way his boyfriend's talented lips work against his skin instead of the burn of magic being forced into his system.

When they are finished, Magnus crawls back up Alec's body, slings an arm around the boy's waist, and rests his head on the same pillow as Alec.
