"Comfortable?" Jace murmurs, fingers running through your hair. He's got you lying on his chest. It's a leisurely morning. It's a rarity for him, but there's nothing to really do today. No Downworlders to take care of, no hunting for demons.
Jace just woke up and waited for you to follow suit. "Is there anything you wanna do? Eat out, stay in?"
He doesn't get an immediate answer, and that's okay. Because you both have all the time in the world. All the time in the world until something goes wrong, that is. Jace admires your features for a moment before letting sleep claim him again.
He starts to drift, keeping himself awake by tapping on your waist where his hand rests. Jace lets you listen to his heartbeat. It's slow, relaxed. His chest rises and falls rhythmically. It's an almost domestic situation.
Jace is just about to fall back to sleep when he feels another touch — your fingers. He opens his eyes to see your fingertips lightly tracing the runes on his chest. His eyes close with a content hum, comfortable with your gentle touch.
