Person B of your OTP not letting Person A get out of bed by aggressively cuddling them.
Magnus woke up to his alarm, and he angrily waved his hand to turn it off and was immediately greeted with warm arms around his waist.
"Alexander?" Magnus said groggily as he peeled the younger boy off of him, trying to climb out of the bed.
"Where are you going?" Alec said, his voice croaky and hoarse from sleep, putting his arms back around the older man.
"I have an early job," Magnus said, trying to sit up against Alec's strong arms.
"Can't you just stay here for a little while longer?" Alec said, muffled in his pillow and Magnus smiled.
"I can't, people need me." Magnus replied.
"But I need you more," Alec said, looking up at Magnus, his blue eyes glowing.
"Believe me I want to stay, but-," He was interrupted when Alec pulled the older man closer to him, aggressively holding Magnus close to him.
"You aren't leaving until I say you can," Alec said, his voice once again muffled in the pillow.
Magnus felt the warm arms around his waist loosen as Alec fell asleep again, but he made no movements.
He knew he had clients to attend to, but that no longer mattered, not when he was with Alec.
