"I still want to be careful." Because this is Tony and Bruce doesn't think he can ever forgive himself if Tony gets hurt because of him. Tony is somebody very important to him, after all. Even if they didn't do this, Tony was still someone Bruce could and would give his own life to protect. And he knows better than anybody just how hard it is to die when the other guy keeps preventing that.

Bruce shivers as Tony runs his hands over him, little gasps and moans coming out from the back of his throat whenever he brushes across the sensitive spots on his body. He squirms a few times when Tony comes across a few of his ticklish spots, but he manages to settle back quickly and let Tony continue his exploration. He groans softly when Tony leans in for a kiss, trying to return it but failing when he pulls back and Bruce can't help but let out a disappointed whine at that.

His gaze follows Tony down as he shifts, and he watches Tony as he settles between his legs and starts running his hands against his inner thighs. Bruce feels his eyes slidling half-shut as he hums his approval, wordlessly raising the leg Tony is urging upwards. He groans again when Tony starts to lavish attention on it, breath hitching slightly while his grips the bedsheets to try and hold himself steady.

"You know," he starts after a moment, voice breathless but audible all the same. "You're still wearing clothes. Its really kind of unfair."
