Jace felt a hard shudder go through his spine, when he heard Alec's voice like that. Knowing that it was like that because of... what he'd been doing, where his mouth was. That was incredibly arousing and Jace couldn't help the low little moan in his throat when he heard it. Plus, the reassurance that he hadn't fucked up, that Alec wanted him to fuck his mouth, to move, to touch. Angel, he was so gone for this man.

Jace followed Alec's gentle prompts, cautious at first, but gaining more confidence as they started to find a rhythm, panting a little as he slid his hand over Alec's hair, his throat his shoulder, even his jaw, making low little panting groans as Alec got him closer and closer to losing control.

Normally he'd be embarrassed about how short a time he was going to last, but Angel, could anyone really blame him, when given the gift of the sight of Alec like this. "I can't... too good," he whined, not even able to manage complete sentences at this point.
