****WARNING PURE SMUT****

"Magnus" Alec said to get his attention.

"Yes darling?" Magnus had maybe expected a physical or a verbal slap, but not a kiss and a tight hug.

"Jace is an ass, how do he expect me to just…"

"Hey, it's okay. If you do want him, you still want him." Alec looked up at Magnus "You don't think I have noticed the way you look at his ass when you train together, well I do understand wanting his body, he is quite pleasing on the eye, but his personality, don't even get me stated." Magnus just looked back.
"What? You don't think I haven't been in the situation like this before? I have and seen them all too many times, were the persons involved starts going behind each other's backs. It never works unless everybody understands and are okay with what is going on. So, if you want him go join him in the shower."

"But Clary…"

"She left him, even I heard that. Either way it isn't your problem."

"But.."

"Let me put it like this, what do you think you can live with, her being mad at you or always being awkward around Jace because you both know you want each other. He is literally begging for your dick up his ass." Alec blushed as Magnus laughed.

"Why are you not more possessive?"

"Because I know you love me and are gonna come home to me in the end of the day, but we are gonna have some ground rules if this is gonna work out for more than just a one off. We are gonna talk about it over breakfast, but it's not done yet. So, go take that shower, beside you need one you still smell like vomit." Magnus kissed him at the forehead before pushing him in the direction of the bedroom.

-oO0U0Oo-

Jace had finely gotten to the shower; standing under the hot spray did wonders for his sore muscle. He was so far away in his thoughts, he didn't hear the door open. He jumped when he felt hands on his shoulders. He turned around and saw Alec standing there.

"I thought you couldn't do this." Jace said.

"Well I couldn't unless my boyfriend being okay with it." Alec said as he took the washcloth and soaped it with a fruity fragrance washing Jace' chest. It was awfully intimate, too soft for Jace. This felt more like cheating then when Magnus had been balls deep in him yesterday. Jace grabbed Alec' hips and pulled him into a heated kiss. Groping his parabatai.

"Are you gonna fuck me?" whispered in Alec' ear.

"Yeah, I think I might" Alec pumped two pups of the lube bottle standing on the shampoo holder. Alec coted himself generously before fingering Jace just to make sure he was indeed loose enough to Alec start taking him.

Jace was still whet on the inside; Alec knew from experience that sperm needed to be cleaned out after sex, unless you wanted to go around slowly leaking with it. Alec gaped one of Jace's legs and guided himself into Jace as he moaned deeply. The position was awkward it didn't take the blond to ask: "Do you want me to turn around?"

"Maybe it would be better." Alec said with a rough voice. It didn't take long for them to reposition them self with Jace slightly bend over with both his under arms on the wall as Alec fucked into him, kissing and biting Jace' neck and back.

The water was burning hot to the skin, but somehow it felt mild to the fire that ignited Jace's insides. It didn't take him long to come so hard that he painted the wall in front of him. Jace felt his arms shake and his knees go weak in his afterglow. He had just only gotten fully back to the world when he felt Alec pull out and with what sounded like two pups with his fist spilled himself out over the runes of Jace's back with a groan.

Alec had always wanted Jace, just like this. Wanting him back with a burning desire. Jace turned around and when Alec looked at the rune that bound them together all in him force. They were parabatai, brothers in arms. They shouldn't be anything else. First now the realization hit him, they had broken the law. They couldn't do this again; however, it was all forgotten when Jace reached up and kissed him sweetly on the mouth.

I am dislextic so bare over with my mistakes or don't read... but if you do, I like what to hear what you have to say, please keep a good tone. ;P
