A few days later after the events with the Demonic Ley Lines, Magnus is at his loft talking with Clary and Izzy, and are having a friendly chat. Magnus was feeling a bit better now that his fever is gone, for using too much of his magic to use the Angelic Core to destroy all the Demonic Ley Lines.

"So Magnus, how are you feeling today, after what happen a few days ago?" Asked Clary as she looks at Magnus.

"I'm feeling much better now, and after that event, my magic is now back to normal." Said Magnus as he smiles and sips his drink.

"It's quite a drink." Said Clary as she looks at her glass.

"It has been quite the day a few days ago." Said Izzy as she looks at Magnus.

"I'm guessing Raj and his friends didn't take their banishment well?" Asked Magnus as he look at the two girls.

"Oh, Wrangle Island isn't banishment." Said Izzy as she smiles." It's more like character building."

"Well, if you ask me, I think Lorenzo Rey could use a bit of character building." Said Clary as she looks at Magnus and Izzy." He's was about to take all the credit for fixing the ley lines, but Catharina told all the warlock's that it was you that fix the Ley Lines."

"Ah yes, I have been receiving every single text from the warlock's that they are very grateful that even though I'm no longer the High Warlock of Brooklyn, I'm always there to protect them." Said Magnus as he smiles." Except I got this hateful message from Lorenzo that I'm still behind the Demonic Ley Lines."

"Such an ass." Said Izzy as she looks annoyed.

"Whatever corrupted those ley lines is still out there." Said Magnus as he look worried.

"And Lorenzo has to stop blaming you for being Asmodeus' son, and help us track the demon who's responsible." Said Clary as she frowns a bit.

"I just don't get why Lorenzo Rey accuse you for that Magnus, I mean sure you're the son of Asmodeus the Greater Demon, but you are nothing like him Magnus." Said Izzy as she touch Magnus's shoulder.

"Thank you Izzy." Said Magnus as he smiles at Clary and Izzy." You know, to be honest, I still feel like my father does care about me, I still remember the first time I met him."

Then Magnus have started to remember the first day he have met his father after his mother committed suicide and he killed his stepfather.

Flashback

Magnus was around ten years old when his mother died and he killed his stepfather, he was living in the streets, and he doesn't know who he really is and doesn't know what to do. As he look at his mothers blade, and started to cry a bit.

"Why did mommy have to kill herself, and why did I kill my stepfather?" Asked Magnus as he cries.

As he kept on holding his mothers blade close to him, he then started to see a shadow covering most of the light, then Magnus started to look up to see a man standing in front of him. It was none other than Asmodeus smiling at Magnus.

"Who are you?" Asked Magnus still a bit crying.

"Do not be afraid my son." Said Asmodeus." I'm your father, Asmodeus."

"Asmodeus, as in the Prince of Hell?" Asked Magnus as he started to feel scared." Stay away from me!"

"Don't not be afraid Magnus, I know you may be scared, but you don't have to be." Said Asmodeus as he shows his cat eyes." See, I'm just like you Magnus, I'm a warlock."

Then Magnus saw that Asmodeus has the same cat eyes like him, then Asmodeus started to look at the blade that Magnus is still holding in his hands, and then Asmodeus started to speak.

"The women known as your mother have abandoned you because of who you are." Said Asmodeus as he looks at Magnus.

"My stepfather said that I was the one who caused my mother to kill herself and that I was an abomination." Said Magnus as he cries a bit.

"Your stepfather is the abomination, he doesn't realize that you are much more powerful, and that you are special." Said Asmodeus." Because you are a warlock."

"But I don't even know what to do." Said Magnus as he still cried.

"Then let me help you my son, let me show you the way what it mean to be a warlock, and it will help you use this pain you have to make you stronger." Said Asmodeus as he smiles at Magnus.

Then as Magnus look at Asmdoeus an saw him opens his arms to him, Magnus started to walk to him and he started to hug Asmodeus as he cried at how his mother killed herself and have abandoned him, while his stepfather called him an abomination, and Asmodeus hugs Magnus back as she tries to calm him.

"Sh. . . I got you." Said Asmdoeus as he continued to hug a crying Magnus.

End of flashback

"Magnus, are you okay?" Asked Izzy as she looks at Magnus.

"Oh, yeah I'm okay, I guess I was still think of how my father is doing now." Said Magnus as he look at his glass.

"I'm sure he's doing fine, and by fine, I mean torturing my father's soul." Said Clary as she sips her drink.

"Well, I can't say I blame him anyway." Said Magnus as he look at Clary.

Then Magnus's phone have began to ring a bit, then he pick it up and saw that it was a text from Alec, and reads a bit.

"Hey Magnus, who is it?" Asked Izzy as she looks at Magnus.

"It was Alec." Said Magnus as he finished reading his text.

"Oh really, what did he say?" Asked Clary as she got curious.

"He said that he is very busy today about with all the paperwork he has, all the shadowhunter's that are report with some demons, and more." Said Magnus as he explains." He's not sure if he'll be back in time for our date night."

"You guys do date night?" Asked Izzy in surprise.

"Yeah, every Friday after he's done with work, we always have a date night." Said Magnus as he smiles.

"That's good, but I don't think you might have a date night, cause he's going to be sore tonight." Said Izzy as she rolled her eyes.

"What makes you say that Izzy?" Asked Clary as she looks at Izzy.

"Because when Alec has the much work to do, his body aches so much, I remember this one time he was training to much, he was so ache he couldn't be able to move." Said Izzy as she explains." I swear, on that day, Alec stay on his bed for a few days and we have to help him get ice."

"Wow, I bet that must've painful for Alec." Said Clary as she look at Izzy.

Then Magnus started to realize that maybe Izzy might be right that he and Alec might not go out for date night, but then when Izzy mention how sore Alec might be after work, it got him a great idea for date night, that it got him to smirk.

"Magnus, is everything okay?" Asked Izzy as she looks at Magnus.

"Yeah, do you have something in mind?" Asked Clary as she looks Magnus.

"Isabelle do you have any body massage oil and any red glitter nail polish I could borrow?" Asked Magnus as he look at Alec.

"What?" Asked Izzy in shock as well as Clary." Why?"

"Can you at least get for me please?" Asked Magnus as he look at Izzy.

"Okay, I guess I can, Clary can you come with me?" Asked Izzy as she looks at Clary.

"Sure, I'll create my portal." Said Clary as she takes out her stele.

Then Clary started to make a portal, then she and Izzy have both started to go through it, and Magnus started to wait for them. Then a few seconds later, the portal appeared again, and Clary and Izzy both step through the portal, while Izzy has a bottle lavender massage oil and red glitter nail polish.

"Okay Magnus, heres the massage oil you ask for and the red nail polish, which has a bit of glitter." Said Izzy as she hands them to Magnus.

"Thank you my dear." Said Magnus as he grab them and smile.

"But what do you need them for Magnus?" Asked Clary as she still look really confused.

"Let's just say that I had a special plan for date night with Alec and let's just say that he might enjoy it." Said Magnus as he smirks a bit." And I need to get ready."

"Wait, that's it, you sure you don't want to talk more?" Asked Clary as she look confused.

"Oh I would love to keep talking to you two more, but I need to get ready for tonight, and let's just say that Alec will need a special treatment." Said Magnus as he smirk.

Then Izzy and Clary say goodbye to Magnus and started to leave the loft, then Magnus started to enter his bedroom, then as Clary and Izzy are both outside of the building, they were both wondering what Magnus is planning.

"What do you think Magnus is planning?" Asked Clary as she look confused.

"I don't know, but I don't understand why Magnus needs. . ." Said Izzy as she was about to continue.

Then before Izzy could continue to say anything else, it got her to get really shock and understand what Magnus is planning, then when Clary saw the look on Izzy's face, it got her to get curious.

"Izzy, is everything okay?" Asked Clary looking so curious.

"Wait a minute, Magnus ask for body massage oil, and nail polish for him." Said Izzy as she started to smile." Do you think that Magnus might. . ."

When Izzy look at Clary with that same smile on her face, it got Clary to final realize what Magnus is planning to do with Alec for their date night, and it was Clary's turn to smile and then she started to speak.

"Okay Izzy, I'm going to bet you twenty bucks, that Magnus will seduce Alec while massage him." Said Clary as she smirks.

"Oh, you are so on Clary, I'm betting that Alec will love that." Said Izzy as she smirks." I can't believe that Magnus and Alec really like having sex with each other, and I cant Magnus is going to this to Alec."

"Hey, everyone loves a good massage." Said Clary as shrugs a bit.

That got Izzy to agree with Clary with that and then they both started to go back to the New York Institute. Then a few hours later at the Institute, Alec started to get ready to go back home, but he still feel really sore all over his body, except for his legs, and he started to put on his jacket and started to leave.

Then as Alec was about to leave the Institute, he saw Izzy and Clary inside Clary's bedroom, playing some game with cards as they were both sitting on Clary's bed.

"Do you have any twelves?" Asked Clary as she look at Izzy.

"Only when it's my pay day." Said Izzy as she looks at her cards." Oh, I mean goldfish."

"Hey girls, I'm going to Magnus now." Said Alec as he look at Izzy and Clary.

"Okay Alec." Said Izzy as she smiles at Alec." See you in the morning."

That got Alec to smile at Izzy and Clary and then he started to leave the Institute, as he have left the Institute, Izzy and Clary both started to smirk at each other, and knowing that Alec might have a great time with Magnus tonight.

"Magnus, I'm home." Said Alec as he went inside the loft.

Then Alec started to put his bow and arrows at the closet and still feel a bit of pain through his arms, neck, chests, and a bit of his abs. Then Alec started to realize that he hasn't had a response from Magnus, them Alec made his way to their bedroom.

"Magnus?" Said Alec as he open the door.

Then when Alec have enter the room, he started to really surprise at the sight of the bedroom. The floor was covered with red and white rose petals, there were candles lit around the room and there were a bit of rose petals covering the bed a bit. Alec was a bit impressed of the room as he closed the door and didn't realize that someone is behind him and that person is none other than Magnus.

"Hello darling." Said Magnus as he smiles.

"Hey Magnus, I'm sorry I made us had to miss. . ." Said Alec as he was about to continue to speak till he saw Magnus and his eyes widen." Wow!"

Alec is glued to his spot with his eyes widen. There behind him, is Magnus Bane in a very seductive pose, his head propped on one elbow. He has a long sleeve red silk shirts that opens up bit to see his bare chest and has red silk baggy boxer shorts on. He has red glitter eyeshadow on, his head has two red tips which makes attractive, and he covered in gold glitter, from chest to toe.

Alec was really speechless at how Magnus is now and he could barely take his eyes of him. He slowly took steps towards the bed but was stopped by Magnus as he raised a figure to Alec.

"Wait a second, take your jacket and boots off first, handsome." Said Magnus as he smiles at Alec.

Then without having to have any argument, Alec started to take of his jacket and boots off as well as his socks, but his eyes never left Magnus, who slowly began to walk towards Alec, and Alec started to blush really red and couldn't be able to speak.

"What's the matter, darling?" Asked Magnus as he got closer to Alec." Cat got your tongue?"

Then Alec started to swallow a bit and he shook his head, as if to deny the accusation and shake his shock at the same time. Then as he look at Magnus, he started to speak as he still feel a bit nervous.

"By the Angel, you look so hot." Whisper Alec as he look at Magnus.

Then Alec started to move forward to Magnus, but as he reached to Magnus to lean for a kiss, Magnus started to place a finger to Alec's mouth, and push him a bit away from his face.

"Uh-uh no touching!" Said Magnus with a mischievous smile.

"What?" Asked Alec in frustration.

"You can't touch me. . . Not just yet." Said Magnus as he brush his finger across Alec's face gently.

Alec's eyes wandered over Magnus' glittery chest, then he started to look at Magnus's hands, and look at his nails. Magnus's nails were painted in a shimmery red glitter, which made him blush even more red than he is. Then Magnus started to notice Alec's lingering gaze on his painted nails and smile at him.

"It's called Royal Glitter Rose." Said Magnus as he smiles at Alec." The nail polish."

"It looks really nice." Said Alec as he moan a bit.

"Oh, so you like it?" Said Magnus as he smirks.

Then Magnus slowly started to move his hands down from Alec's body, till he reaches the end of his shirt, while keeping his gaze on Alec's face, and he started to take of Alec's shirt, and then Alec let out a low moan as Magnus started to lift up hid short, and locked eyes on Magnus again. And as Magnus took Alec's shirt off, he saw that his muscles started to feel harden and Magnus brushes his hands all over Alec's muscles.

"Someone's already half hard." Said Magnus with a smirk as he move his hand all over Alec's chest.

"It shouldn't be surprising." Said Alec as he moan a bit.

"Oh, how so darling?" Asked Magnus as he turn Alec around and hug him behind.

"Look at yourself." Said Alec as he look at Magnus." It's not that hard to figure out."

That got Magnus to smile at Alec, then he started to kiss his neck, which caused Alec to moan a bit more. Then as Magnus kept on moving his hands all over Alec's chest, Alec place his hand over Magnus's.

"What else is nice?" Asked Magnus as he smirk.

"Everything." Said Alec as he moan and turns to face him.

Then Magnus moved closer to Alec and slowly slid his hands down until he reach Alec's abs, which made Alec have a shivering effect. Then Magnus's beautiful cat-eyes appeared, which made Alec really attractive to him.

Then Magnus started to lean over and kiss Alec at the lips, which got Alec to kiss Magnus back, as he wrap his arms around Magnus's waist, and then after they finish their kiss, Magnus started to move his hands over Alec's arms and neck which got Alec to groan a bit.

"I see that you had a rough day." Said Magnus as he smiles at Alec.

"I'm a bit sore right now." Said Alec as he groan a bit and Magnus lean closer to his ear.

"Then let me help you." Whisper Magnus and Alec blush really red." Lay down on the bed."

Then Alec started to go towards the bed and started to lay on his back, as he puts hands behind his head a bit, and then Magnus started to get on the bed and crawls to Alec, and then Magnus pulls the covers over Alec except for his bare chest and stomach.

"Now just relaxing darling, while I give you a bit of pleasure for tonight." Said Magnus as he smirks at Alec.

It cause Alec to blush really red at what Magnus have said, then as he tried his best to relax, then Magnus started to pick up the massage oil that Izzy gave to him, then he started to pour some over Alec's chest and stomach which made him shiver.

Then as Magnus put the massage oil bottle down at one side, he started to massage Alec's chest first, and Alec started to moan in pleasure. Alec started to like the way how Magnus's hands massage his chest, which made him arch his back a bit.

Magnus started to smile at how Alec is moaning at the pleasure of him massaging his chest, then Magnus started to move his hands down to Alec's stomach and abs, and Alec started to moan louder as Magnus massage him.
