Bruce smiles at Tony's reaction, feeling oddly proud that he had managed to get such a strong response from him. The sensation is heady, just on the edge of overwhelming, and it makes him just a little but more daring. He withdraws with a soft pop but continues to hold Tony's wrist in his grip as he brings the hand back down to his side.

"I've been known as a generous man," he murmurs back, voice low. "So I'm sure that we can--" Bruce cuts himself short when Tony has his hand in his pants again, eyes falling shut as he moans at the tease. "--we can work something out."

His hands are starting to scrabble mindlessly again, but they manage to settle on gripping Tony tightly by his hips as Bruce forces his eyes back open and looks at him with another smile.

"I'd rather not wear out your knees if we can manage that. Let's actually get to bed."
