Bruce returns the grin with another wry smile, although its effect is dimmished when he closes his eyes and lets us a breathy sigh when the fingers brush across one of the more sensitive spots at his side.

He opens his eyes to look at Tony, nodding. "I will," he promises back, because this is still new territory for him. Being this close to somebody... again, he would rather not risk anything if he can help it. If this all goes well, then its already more than he can ask for.

Taking the offered hand, Bruce can't help but feel a rush of warmth on his cheeks when Tony compliments him. He had never been wholly concious of his looks, but its hard not to be after hearing something like that. Bruce ducks his head, embarrassed, but replies to it all the same. "Um. Thanks, I think."
