Alec let out a quiet sigh as he thought about that request. He wanted to say yes and he knew that even if it sounded like a bad pick up line, Sebastian wasn't trying to seduce him. But he couldn't agree without checking with someone first. "I trust you. I'm not... Kissing is one thing. Anything else... " He might have moved fast with Magnus but he wasn't ready to do that with Sebastian until he was certain that there would be no guilt afterward. "I have time and I want to but I need to ask Magnus first. I don't want him thinking the wrong thing."

He doubted that his boyfriend would. They'd talked about this enough that Magnus would trust him but after all their issues with trust, Alec couldn't act without Magnus knowing.

"I want you to be yourself. But you were wrong. You shouldn't compare yourself to Magnus. You're pretty and amazing in your own way." Pausing, he chuckled softly. "No one can be amazing the way he can."
