It happens much the same every time. They can - and have - tried to tell themselves that they would do x before falling into each other, but it rarely happens. Even if it's a reunion with all of them, if Cassian and Jyn also haven't seen each other for a while, they're bound to sneak away for even a few minutes gloriously alone.

They are already alone now, that's one of the perks about this house. Jyn tries to climb over the railing and Cassian's hands move, running along her thighs and trying to get a solid grip to help the process along. Sometimes it feels like nothing is close enough. It's a struggle even now that could be helped if they would stop kissing for five seconds, but that is simply too much time as far as Cassian is concerned.

He manages to help her get one leg over it, and she immediately curls it around his waist, yanking him in closer. He laughs against her mouth, the sound soft and swallowed up immediately when she bites at him. He forgets about her other leg for a second and just presses in again, one hand creeping up the back of her shirt, the other firmly settling at her ass, a favorite place for both of them.
