Chapter Text
Students were gathered around Magnus in his apothecary. He had been teaching them about potions and the difference between certain ingredients that are used for the different potions. As he glanced out toward the balcony, he realized how late it was. Alexander was also due soon and knowing from a very brief text earlier, his husband was having a rough day. He clapped his hands and smiled at his students.
"I think that's enough for today. Our next class isn't until Friday so I want you to read the next two chapters in your books on potions. Study them carefully as next class we will be putting all of what we learned into practice. Now, I know many of you know how to mix potions however, there is still practice to be had. There are many potions that require a certain level of skill and if you are not skilled enough, your potions will fail."
Magnus chuckled at the groans and answered a few questions before dismissing the students, they all filed into the living room as they left the balcony and headed for the door. Some stayed behind to ask Magnus questions, one of them being Cassandra, she had asked him if he could create a potion for her to help her with sleeping.
Cassandra was one of Magnus's newer students. She moved here to Brooklyn just a month ago at the suggestion of her good friend, the now High Warlock, Lorenzo. It was him who had suggested she take classes with Magnus she had heard about Magnus, who hadn't? What Lorenzo failed to tell her was how attractive he was. And with her being a young and single warlock, it was only a matter of time before she became completely attracted to him.
Now was her chance. While Magnus busied himself concocting her potion, she sat in the living room. After a minute, she removed her top, leaving her just in her bra and skirt. Magnus wouldn’t be able to resist.
“Here you are my-” Magnus stepped out from the apothecary and stared at her.
Cassandra smiled seductively before walking over to him and kissed him, “Like what you see? I know I sure do.”
Before Magnus could speak though, the door opened.

Alec let out a sigh of relief. He was home. He wanted nothing more than to spend the rest of the day with his husband. Today had been particularly rough and he just needed to unwind, he frowned as he toed off his boots and hung up his holster. Where was Magnus? Usually he was running around the loft mixing potions or something. But he didn't hear anything.
"Magnus?"
Alec frowned. He checked his phone to see if he missed a text from Magnus telling him he was going out or something. Nothing. He sighed in frustration as he made his way further into the loft, that's when he heard low voices, as he moved toward the living room, he spotted his husband standing in front of a topless woman. Magnus seemed to have lost his voice. It reminded him of when Camille kissed him.
“I don’t know who you are and I couldn’t care less. You need to leave. Now.” Alec said sternly.
Cassandra glared at him. She may be young but she wasn’t new to shadowhunters, “I don’t know who you think you are shadowhunter but you can’t just barge in here and give me orders. Now if you don’t mind, we were in the middle of something.”
Magnus cleared his throat, “Actually, no we weren’t.”
Cassandra turned to him, “But dear...we would've been if we hadn’t been so rudely interrupted. Now, how about you tell this shadowhunter to leave so we can finish our business.” She stroked his chest.
Magnus stepped back, “No. First of all I’m not going to tell Alexander to leave. This is his home. You are the only one not welcome. And it's time you leave.”
Cassandra snarled and her magic swirled around her fingers and she launched it toward Alec, “Stupid Shadowhunter! You have no business here!”
Magnus quickly intercepted the magic, “Perhaps I didn’t make myself clear. And while I understand you are young Cassandra, there is something that your dear friend Lorenzo forgot to mention. I do not like being toyed with. I do not allow anyone to hurt my husband. Perhaps Lorenzo forgot to mention that tiny fact, but the fact of the matter is Alexander Lightwood-Bane is my husband. And if anyone, and I mean anyone, hurts him, they will feel my wrath. And I do not mean banishing you to the Spiral Labyrinth if you catch my drift. Leave. Now.”
Cassandra gaped and before she could say anything, Magnus was opening a portal and tossed her shirt to her before pushing her through. “Oh and I don’t want to see you here again,” he said before the portal closed behind her.
Magnus turned to Alec, “Alexander, I am so sorry, I-” He was cut off by Alec kissing him deeply.
“Magnus, you don’t have to apologize. I could tell this wasn’t your doing. You looked the same way when Camille kissed you, remember?”
Magnus smiled, “Still I apologize. You had a rough day at work and then you came home to see that. But I have the perfect remedy to ease your frustrations.”
Alec grinned “Lead the way Mr. Lightwood-Bane.”
◇◇◇◇
"Lightwood-Bane?! Lightwood-Bane?! He married a shadowhunter?!" Cassandra was furious and having a full on tantrum. Complete with throwing things across the room, breaking glass…
She couldn’t believe what she had heard. Everyone knew Magnus Bane. He was the former High Warlock of Brooklyn. He was one of the most powerful warlocks in the world and the son of Asmodeus, one of the former princes of hell. The last she had heard was that he was now the High Warlock of Alicante. And she could see why. Because he married that stupid shadowhunter. Cassandra moved to her apothecary and pulled out her potion books. Magnus wanted them to study. Oh she was gonna study. She was going to find a way to make Magnus hers.
