It's enough to satisfy J's concerns, sure that S means what he says. He huffs, smiling, as S nudges at him and lets himself be guided, turning to lean back against the wall. "As long as you're sure," he says lightly, ducking forward to give him another quick kiss. He's hardly about to argue about this. He can't help it if getting S off turns him on. There's just something deeply fulfilling about being able to make him feel good like that, not to mention knowing no one else could or has. S hasn't explicitly said so and they were apart for a long time, so J knows, if he's wrong about this, he couldn't fault S for finding other company, even if he'd also be incredibly jealous. He doubts he is, though. It's not like breaking up put an end to their feelings, clearly, and he can't really imagine S seeking out someone else so soon. It's a comforting thought, if bittersweet to know they were both so alone.

He lifts a hand to sweep S's wet hair back, lingering against his cheek. Now that he knows what's coming, now that they're both sure, he can't keep his need entirely in check, anticipation curling low in his abdomen before S is even on his knees, but that's part of the fun.
