They look at each other. Neither one moves.
"Well... get to it." Draco says impatiently when he has enough.
"Now?" Potter asks shocked.
"Of course now, Potter. I want to get this over with."
Potter swallows, looks unsure.
"Okay." he says but remains still.
Draco sighs.
Suddendly Potter steps closer. He looks into Draco's eyes and Draco sees what Potter's been trying to hold back. There's desire and conflict and guilt in his eyes and Draco's relieved. It almost seems as if Potter is helpless against his need. He's certainly not as in control as he wants Draco to believe and that makes it a lot more bearable.
Potter kisses him.
Draco stiffens automatically, but relaxes when he realizes he's meant to reciprocate.
At first it's just a gentle touch of lips, but soon they're kissing for real. When their tongues touch for the first time, it's a little sloppy and almost as if Potter doesn't quite know what to do, but not altogether that bad.
After a few minutes he's gotten used to it. It's just kissing, not painfully arousing, but not unpleasant either. He almost forgets it's Potter.
He vaguely realizes there's suddendly a wall against his back. Potter chooses this moment to abandon his lips in favor of his throat and Draco arches into the open-mouthed kisses along his neck.
He has just decided he likes this even better, when Potter catches his lips again and resumes kissing him. Draco, partly instinctually and partly because he wants to punish Potter for stopping the neck-kissing, bites down on his lower lip hard.
Instead of protesting Potter responds in kind and Draco makes a startled sound.
He only realizes his hands are clenched in Potter's shirt, when Potter takes one of them, without breaking the kiss, and guides it down to where his cock is straining against his jeans. He suggests a slight rubbing motion and lets his hand fall to Draco's hip, when Draco starts copying it.
It's a little strange doing this to someone else, but it's okay, after all there are still several layers of clothing between them.
