A/N: My first time writing such a scene. Be warned.

Chapter 3

Magnus was walking around the house. He had lost Alec while he got himself a drink. Soon he found him, together with Logan. The music prevented him from eavesdropping, so he got nearer –till he could make out the words. Logan sounded angry. "You have to tell them! At least Isabel. You can't lie to her, it would make you feel worse." Alec huffed. "Thanks to you, I don't even know if she will talk to me again." Logan crossed his arms in front of his chest. "Well, I didn't know that you knew them! You never told me anything."

Alec raised an eyebrow. "As if you ever tell me anything. I only know your name."
"So do I. It's part of our deal remember?"
Alec nodded. "Yeah I remember." He looked around and saw Magnus. "I'm going home. Do you want to come?" Magnus' response was to grab Alec's arm and drag him out. "Call me when you sort it out!" They heard Logan over the music.

Isabel took the car, so they had to grab a cab. Magnus was the one to break the silence. "What do you need to tell us? Or Isabel?" Alec glanced at him. "I don't want to tell it twice. Wait till we arrive." Magnus shrugged and turned to the window. He heard Alec sigh but didn't want to ask. At home they found Isabel sitting on the couch, still dressed. As soon as she saw them she stood up and walked to Alec. "What the hell Alec? Why didn't you tell me that you were here before?"

Alec rolled his eyes. "I told you. Remember the masked party two month ago?" Isabel nodded. "And do you remember how I called you?" Alec sighed. "Probably not. You were too drunk." Isabel frowned. "I do remember that you called, but I don't remember what we talked about."
"I told you that I was at the train station in New York, to surprise you. But you said that I should come to this amazing party. The next second you hang up and send me a text with the address. But I couldn't find you there. Actually I might have found you but everyone was masked, so I probably didn't recognize you." Isabel didn't say anything at first.

"And what's with that Logan? He said you always stayed with him." Alec shrugged. "He likes to exaggerate things. I only stayed a night at his place. Cause you didn't answer your phone. And I had his number from the party."
"You met him there?" Alec nodded. "He gave me a mask, since I didn't had one." He chuckled. "It was a purple one with pink stars on it. I bet I looked hilarious." They heard Magnus gasp but neither one paid him attention. "So you…" Alec held out a hand. "I don't want to talk about that anymore. I didn't lie to you or hide anything from you. So if you still want to blame me for something I didn't do, keep it to yourself." He turned around and walked into his room.

Isabel looked after him till he closed the door. She turned to Magnus. His face was pale and he had a shocked expression on his face. Isabel ran to him and sat him on the couch. "Magnus. Are you okay?"

Flashback

Magnus got himself a drink and wandered around. He long had lost Isabel to some guy and had his own fun with another awhile ago. Something red caught his attention and he turned to it. A small guy with flaming red hair was putting a purple mask on someone. That someone was wearing a pair of tight black jeans and a black long-sleeved shirt. His hair was pitch-black. Magnus couldn't see his eyes. He walked to him and waited till the red-haired guy walked away. "That's a nice mask you have there." He said putting a hand on the black-haired guy's waist. The guy yelped and moved aside.

"Thank you." He said with a soft voice. Magnus was mesmerized. The guy had the most beautiful blue eyes that he had ever seen. "Are you new here? I never saw you at any parties." The guy nodded. "I came to visit my sister. But I can't find her." He pouted. Magnus wanted to bite those lips. "I could help you. If you want." He said. The guy looked at him and nodded slowly.

They spend almost half an hour but they couldn't find the guy's sister. Magnus didn't even knew how she looked. "What about a drink? We can continue our search later." The guy nodded slowly again. They drank and drank and Magnus lost count on the shots they had. The guy stood up from the stool and swayed a little. Magnus chuckled. He could hold his drink very well but the guy apparently not. "I should… I should… look… sister." He slurred. "I think you need a bed." Magnus countered and dragged the guy with him.

Magnus found an empty room and walked the guy inside. As soon as he closed the door he felt someone press at him. He turned around and lips pressed at his. It was sloppy. So Magnus held the guy's head and turned them around. Pressing the guy flat at the door and kissing him back fiercely. He bit into the guy's bottom lip, causing him to gasp in shock. He took advantage and sneaked his tongue into the guy's mouth. He broke the kiss and attached his lips on the guy's neck. The guy was moaning but Magnus didn't stop till there was a mark. He then dragged the guy to the bed and undressed him. He pushed the guy onto the bed.

The guy fell on the bed naked and his leg spread. Magnus licked his lips and removed his shirt. He knelt between the guys legs and started licking him. From his neck to his nipples, down to his belly button where he dipped his tongue into the guy's navel. Magnus looked up at his face and smirked. The guy's face was red and he was a moaning mess. Magnus lifted one of the guy's legs and bit in his thigh. The guy screamed. His cock was hard and was already leaking but Magnus didn't go near it.

Magnus kissed the guy again and put a finger in his hole. The guy screamed and allowed Magnus to ravage his mouth again. Magnus attached his lips to the guy's left nipple as he added another finger. The guy was panting as Magnus started to stretch him. Magnus kissed the guy's chest to his right nipple adding a third finger. Magnus touched the guy's prostate and the guy screamed. Magnus smirked. He took his fingers out and released the nipple. He took off his pants and positioned himself in front of the guy's hole. He stopped as the tip of his cock pressed against the other's hole. "What's your name?"

"Alec." The guy panted. And Magnus entered him with one swift move. "God, you're tight." Magnus mumbled and started moving. Alec wasn't able to form any words. The only things leaving his mouth were pants and broken gasps. Magnus' thrusts fastened and after a few more thrust Alec came all over his stomach without being touched. Magnus lasted for three more thrust before emptying himself inside Alec. Magnus fell on top of Alec and raised himself on his elbows. Alec was looking at him with his bright blue eyes. The mask was still on his face, a bit displaced but still covering a lot from his face. Magnus rolled beside him and soon both fell asleep.

End of Flashback

"Isabel." Magnus said with a broken voice. "I think I fucked your brother."
