Part I: Day One

"What are you doing here?"

"Watching my boyfriend workout." Magnus glanced sideways at Alec but kept his primary focus on Jace. His target for the next two days. He made a deal with Alec fair and square and even if he didn't get his fast dance in the traditional sense, he couldn't argue with the dances he did get. So here he stood in the corner of the training room. Izzy and Clary were off to the side watching Jace and Alec spar until Magnus showed up and stopped them from spar by just being in the room.

"You aren't going to use magic on me if I kick your boyfriend's ass, are you?" Jace taunted him.

Alec shook his head, Jace was the better fighter but he didn't always land on top. Alec did get the best of Jace from time to time.

Magnus thought for a moment, he needed to choose his next words very carefully, "I promise I won't use my magic against you for beating my boyfriend." There he wasn't going to use his magic because Jace beat Alec, no, he was going to use his magic because he made a deal with Alec. And the fun little trick Alec did with his tongue on his couch earlier that morning. A trick he was hoping to get with a repeat performance soon. His shy Shadowhunter turned confident in an instant when it was just the two of them behind closed doors. Those were the moments he lived for. Those moments that Alec only shared with him. Whether they were reading a book, talking, or having sex; those were the moments he loved. He hated calling it just sex with Alec because deep down he knew it was more than that but it was so soon, way too early in their relationship to call it anything but sex.

One day Alec would come out of the closet for himself and that was a day Magnus couldn't wait for but he would wait because Alec had asked him to. He loved Alec enough to do that even if he hadn't told Alec yet that he loved him in the traditional sense. There all these moments that weren't traditional but it didn't matter because it was theirs' and that was the critical part.

Alec rolled his eyes, "Let's go, little brother." He threw the polearm to Jace, the sharp lance had been taken off for practice purposes.

"Oh, my Alec, so hot." Magnus winked at them.

Clary grinned at Magnus as he seemed to float around the room to them, he was graceful and gentle in his step. "Simon and Izzy confessed." She whispered when he got closer, she knew the walls in the Institute were always listening.

Izzy smirked at him, neither of them watching the boys practice.

But Magnus was, he was watching every movement with his cat eyes glowing. Alec was wearing long black pants that were loose fitting and swayed with his every step. His shirt was a thin material that was almost a perfect fit and showed off every muscle. He didn't matter that he had Alec naked in his bed all day and most of the early morning, it was still the sexiest thing he had ever seen.

"Magnus, you're drooling," Clary spoke up.

He didn't take his eyes off of Alec, clashing with Jace. They both had smiles on their faces, clearly enjoying the moment.

"I've never seen him work out before."

Izzy and Clary snickered, "Clary, I almost want to take Jace and run. I think Magnus might strip Alec naked right here in the training room."

"No, darling Shadowhunter-in-law, I did that already this morning in my living room." Magnus grinned at them for just a moment, he put his hand behind his back and snapped his finger. He knew the girls would see it but they knew what he was up to anyway so hiding his magic from them would be pointless, and this way he had a greater chance of Jace not seeing him.

They heard a clash that sounded like someone hitting the floor and they looked up to see Jace down on one knee with Alec a step back from him with a grin.

"Clary, fair warning, if you notice Jace covered in glitter in about a week or so just know it was not me but, just know he can't wash it off. It will wear off in a day or two." Magnus looked her over then at Izzy, "What's your favorite color?"

"Red."

Magnus winked at her, "Good, that will be the color of the glitter." Clary and Izzy giggled, they suddenly couldn't wait the week to be up.

Jace looked over at them but he couldn't see anything wrong, so he turned back to Alec.

"What's wrong Jace? Not doing so well?" Alec held out his hand to help Jace up.

Jace slapped at Alec's hand and helped himself up, "Magnus did something. The pole got hot and it hurt." He picked up the pole gently, testing it in one hand then the other.

"We've been watching Magnus the whole time." Clary called out, "He hasn't done anything."

Jace got back into position, "Let's go, big brother."

Alec laughed at the term. He circled around him and eyed Magnus off to the side with Clary and Izzy; he tried not to laugh, so he bit the inside of his cheek instead. Todays' workout was going to be so much fun. He swiped his pole out while dipping down, Jace was just slow enough that Alec hit his leg and both legs went out from underneath him.

Jace flipped to break his fall but wasn't fast enough as Alec twisted around bringing his pole with him and hitting Jace in the stomach mid-flip. Jace couldn't rebound and landed on his back; hard with a grunt at the pain. Jace let out the swear before he could think, the floor hurt to damn bad to stop himself, "Fuck."

Alec smirked, turning towards Magnus he smiled, that was all him and they both knew it. Jace was getting unnerved and that was causing him to make small mistakes. Small mistakes that he and Magnus were using to exploit.

Magnus winked at Alec when he saw Jace close his eyes and snapped his fingers again, his magic turned clear to anyone who was looking except for Alec. He already warned his boyfriend he would be using a small glamour to hide his magic so don't focus on the magic. Magnus had advised him to focus on his eyes if the magic became too distracting. He knew Clary and Izzy would wonder where his magic went but he wasn't going to let up the glamour to anyone except for Alec.

He blinked and Jace's raised head hit the floor, very lightly but the pressure he applied did the trick. It was gone in an instant. Magnus smirked.

Alec held out his hand to Jace, "I'm showing off for Magnus, you know."

"Oh, I'm aware." Jace stood up and shook his head. "Damn, that hurt." He rubbed his hands along his back but them seemed to be hot and he felt heavy all over.

Magnus grinned at Jace's discomfort, it was all a spell. A simple spell, but a spell nonetheless. It would only affect a person as long as the person allowed or until the warlock let the spell give, and Magnus wasn't in the giving mood. "Good job, Alec." He looked to Clary and Izzy, "That's my hot boyfriend."

They only continued sparing with the long poles for another half hour with relative ease, going back and forth on an even playing field for the winner. Each round rotating between Jace and Alec.

Alec went over to Magnus when they claimed to take a break, picking up the water bottle by his feet. Clary and Izzy moved over to speak with Jace.

"How does Jace like his showers?" Magnus asked.

Alec, not excepting the questions, stuttered and coughed up water. Everyone turned to look at him but he waved them off, "What?"

Magnus narrowed his eyes, "I was going to mess with the temperature of his shower but now I'm annoyed with you for thinking of him in the shower."

"For the record, I was not thinking about him in the shower; and you're the one who asked how he likes his showers." Alec wiped his mouth with the back of his hand, "And to be honest, I don't know. I've never showered with or near Jace." Alec gave Magnus a pointed look. "I have showered with you and I know how you like your showers."

Magnus waved off his response, "I've already decided he'll deal with a cold shower and varying water pressure."

"You think maybe we should talk to Clary and Izzy, see what they think?" Alec asked, stepping up to Magnus to get his hands on his boyfriend, he slid his hand around his jacket to rub his lower back. It didn't take long to get his hands inside his shirt and feel his skin; it was cool to the touch, nothing like his warm hand.

"Oh, a team meeting. Excellent idea, I can magically mess with Jace's shower from anywhere. Gather the girls when the sparing it over and get them to your bedroom in a while." He smirked, "I can't wait to be in your room."

"Don't wiggle your eyebrows at me, this is a meeting. We are not doing anything in that room except for planning your attack on Jace."

Magnus snorted, "You would believe that lie, wouldn't you?"

Alec tried a new approach, "The girls are going to be there."

"We will have a moment before they get there and afterwards, well, they have to leave at some point besides," Magnus ran a finger of his from Alec's neck to his navel, but he didn't stop there. Magnus continued to the bottom of the shirt, hooking his finger he lifted his shirt up just enough to see the top of his pants; not that he was looking as Magnus kept his eyes trained on Alec's. "No one can see. Would you let me touch your skin?" He whispered.

True to his word when Alec twisted slightly to watch his siblings and Clary there was no way anyone could see what Magnus was doing. "You know I prefer private," Alec answered.

Magnus dropped the shirt with a smile, "I know." He pushed on Alec with his palm flat on his naval above the shirt, "Go beat up your parabatai. I like seeing you all sweaty."

Alec smirked at that, "Whatever." He went back to the center of the room, "Let's go, Jace. I need to impress my boyfriend some more."

They went round and round for another hour before Magnus told them to 'stop, Alec is wet enough' which got some groans from everyone in the room. He then responded with 'what' in the most innocent face he could muster. Jace put his and Alec's poles away and headed off to the shower. Alec corralled the girls into his room to plan a little more on what to do to Jace.
