Warning: This is smut! Read only if you want to!
It was a seemingly normal day for the couple. Magnus was working for something for a client and Alec was on the couch with a book. Magnus came out of the study and bent down in front of one of the bookshelves in the living room. Magnus couldn't find it. He heard the soft sounds of Alec breathing and turning the pages of his book. He realized he didn't want to work. He wanted to be with his boyfriend. Very badly. He went into the study and cleaned everything up and walked back to the couch. He stood over the shadowhunter for a moment. He decided to make his move. "Alec what are you reading?" he asked and stood over him. Alec barely looked up. "Just something about aliens" he said. Magnus looked down and saw the tittle. "The Hitchhikers Guide to the Galaxy" Magnus sat down next to him. "Sounds good." Alec didn't even look up and answered blankly. "It is." Magnus sat there for a moment, growing impatient. He moved closer and took the book out of his hand. "We should do something...fun" he smirked. "Like what?" he asked. "Hmm. I don't know.." he leaned in and kissed the shell of his ear. "Something." he whispered. He flicked his tongue out. He heard his boyfriend whimper softly and pulled away. "Well?" he purred. Mangus moved to be sitting on his lap and Alec looked up at him with his bright blue eyes, now darkening with lust. "Okay." he whispered. Alec leaned up and kissed him passionately. Magnus licked his bottom lip, asking for entrance. Alec eventually let him and their tongues tangled together. Alec pulled away for a moment before pulling the warlock's shirt off. Magnus shuttered when the cool air hit his bare chest and stomach. Alec reached up and ran his fingers up and down his chest, stomach and sides. He smirked up at him. Magnus finally pulled Alec's shirt off and stared at his rune covered chest for a little bit. He ran his finger on the one of the runes. "You're so beautiful" he whispered. "Not as beautiful you Magnus." he said back. He smiled at the comment. They went back to kissing passionately. Magnus picked Alec up and carried him to bed. As he was carried, Alec scratched down the warlock's back. They eventually made it to the bedroom and Magnus pushed the shadowhunter on the bed. He climbed on top of him and kept kissing him. Alec reached down to undo the warlock's belt and pants and slipped what was left off of him. Magnus did the same to him. Magnus sat up and looked down at his boyfriend, who was panting slightly. He grinded down on him hardly. Alec let out a soft groan. "Magnus..." He whimpered. He stopped. "Yes darling?" he purred. He lets his hand trace down to Alec's member. Alec arches his back and moans softly. "Please!" he moaned louder. Magnus smirked at his boyfriend, withering in pleasure. He laid down on top of him and started kissing and biting on his neck. Alec reached up and wound his fingers in Magnus's hair and pulled tightly. Alec reached down and strocked his member and Magnus moaned against his skin. Alec shuddered at the action. "I...love you Magnus..." Alec painted out. "I love you too Alec. So so much."
A few hours later, the couple was laying in each others arms; painting and sweating. Alec looked up at his warlock and tracing his stomach. "Magnus."
"Yes love?"
"I love you"
Magnus smiled. "And I love you too Alexander. More than you'll ever know." He kissed his damp temple and shut his eyes. They snuggled up together and fell asleep.
