"You really should learn to assert yourself more, Alexander," Magnus purrs in his ear, drawing the slight boy into his lap. It’s post party, the apartment littered with half empty drinks and trash and… was that a pair of women’s underwear in the corner? Alec shudders and tries to focus on Magnus’s voice instead, a relatively easy thing to do when he’s surrounded by warm warlock and his voice is whispering deliciously in his ear.
"Oh?" Alec raises a silent eyebrow. "What do you mean?"
"I mean…" Magnus leans in a bit and Alec swallows hard, his Adam’s apple bobbing in his throat. "You never initiate anything." Alec can feel his breath against his lips, and he shifts a bit uncomfortably, focusing on the sound of Magnus’s voice. "Learn. To. Assert. Yourself."
Alec blushed lightly, but reached out and grabbed hold of his wrists. “I assert myself just fine, Magnus Bane.”
"There’s my little Nephilim!" Magnus laughed, bending down to give him a kiss on the nose. "Scary as an angry kitten."
Alec glared at him, and Magnus stuck his tongue out. Alec took advantage of his vulnerability and dove forward, gently biting at his tongue before kissing it. Magnus laughed and grabbed his waist, pulling him fully onto his lap and kissing him deeply.
"My beautiful, sweet Shadowhunter," he purred, and Alec smiled before kissing him again.
