What if Magnus convinced Alec to let him dress him up for a day?

"Please?"

"No."

"Pretty please?"

"No."

"Pretty pretty please with glitter on top?"

"No."

"What if I make you breakfast in bed for a month?"

"No. You already do that anyway."

"What if I don't bother you for a whole month about doing anything like this?"

"Make it two and we have a deal."

"Two months."

Alec grinned, shaking the hand of his warlock boyfriend, Magnus. "I'm gonna regret this, won't I?" Alec asked, following Magnus out of the apartment and down the street to a small theater.

Magnus grinned, pushing his boyfriend past a curtain connected to a silver catwalk, chairs surrounding it. "I sure won't," he grinned.

"What are all the chairs for?" Alec asked as he was pushed into a dressing room.

"Paparazzi, baby," Magnus smirked, leaning against the wall just outside the door. "I need some pictures of this for future use for personal reasons and it's not everyday a Shadowhunter does this. People wanted to see."

"You sold tickets?" Alec yelled at him through the door.

"All of them in 2 hours," the warlock told him. "Are you ready?"

"I'm not coming out and you can't make me," the young Shadowhunter said from behind the door.

"Come out or our deal's off and to make it even worse, no sex for a month," Magnus threatened.

Alec groaned and, even though he knew for a fact the warlock couldn't go 3 hours without any form of sex, he opened the door, walking out with his arms crossed. "Happy?" he muttered, turning his gaze to the floor.

"Yes," Magnus smirked. "Uncross your arms and stand still."

Alec held his breath and closed his eyes as glitter attacked him.

Magnus stepped out in front of the curtains, looking around the audience with a smile. More than half of the people sitting had cameras and in the front row, a camera in their hands, were Clary, Jace, Isabelle, Simon, and Maia. "Thank you all for coming," he said, this smile still on his face as he laced his hands together in front of him. "Please, no cell phones, but flash photography is okay. And now, without further a due, I present to you, Alec Lightwood, in the first of many outfits!"

Alec took a deep breath before stepping out in front of the curtain in front of the applauding audience. Magnus' smile grew as much as possible, restraining himself from just jumping the young Shadowhunter.

Alec was in a pair of thigh-high stilettos, a black leather miniskirt that barely covered his ass, and a white tube-top that hugged his torso like a second skin. Glitter covered every available patch of skin and his hair looked like he had showered with it. An almost adorable blush covered his cheeks and the upper part of his neck as he walked out to the edge of the catwalk, flipping Jace off as the blonde whistled at him, Clary taking a picture. Isabelle even seemed to be having a good time, but who could blame her? How often is it that you get to see your older brother dressed up like this and he can't do anything about it?

"I hate you so much," Alec hissed at Magnus as he walked off to change again.

"I love you, too," Magnus replied, blowing him a kiss. And the outfits just continued on and on…and on…and on!

A pair of fishnet stockings, black ankle boots, a pair of denim Daisy Dukes, a tight-fitting white tanktop…

A tight white T-shirt with an open high collar that dipped down halfway down his chest, a pair of rainbow colored skinny jeans, black stilettos…

A blue vest, a pair of tight brown shorts that went down halfway down to his knees, a pair of black sneakers…

A purple tanktop, a flowing brown skirt that went down to his knees, a pair of brown high-heeled sandals…

The list went on and on…and on…and on!

Finally, it was over. Alec walked into the dressing room in his last outfit (a leather corset laced together in the front, a rainbow colored miniskirt, and a pair of knee-high lace up sandals. Hey, who said Magnus didn't have fashion sense? Well, not all the time, at least), closing and locking the door behind him, hearing the faint sounds of people leaving the theater. Sighing, he looked in the mirror, grimacing at the amount of glitter he still had on.

"This is gonna take 3 showers to take off," he muttered to himself.

"Or if you just ask nicely, I'll take it off for you."

Alec spun around, seeing Magnus leaning against the wall with his arms crossed and a smirk on his face. "How the hell did you get in here?" he demanded, glaring at the older.

Magnus smirked again. "Warlock, my little Nephilim," he replied calmly. "Unless you have forgotten." He looked the younger up and down a few times. "Love the outfit."

"I am never doing anything like this again," Alec muttered, turning back to the mirror.

"That is," Magnus moved up, making Alec jump slightly when his breath brushed by his ear, "unless I think up a better deal for you."

Alec turned around, crossing his arms and legs. "I hate you," he said.

Magnus grinned, pressing a kiss to the teen's lips. "I love you, too, babe," he whispered, kissing him again.

***AUTHOR NOTE***

Okay, well, I need some help on something. I plan to do a lemon chapter, but before I do that, I need a 'What if…' situation. So, if you have an idea of a 'what if…' that could lead to a lemon, please send it in. If I like it, I'll use it and I might end up using all of them.

Thanks for your help! XD
