The sex is good. The sex is great, actually, because Bruce is so responsive and Tony honestly finds the way he begs so sexy. It's something he'll remember for later, possibly after they're done in the lab and Bruce is distracted from his worries by the brightly lit science Tony intends to shove his way.

But right now Bruce in his arms and pressing against him tightly puts the rest of the night to shame. The man is a cuddle bug. And while Tony would usually avoid that kind of intimacy, with Bruce, it's practically impossible not to love it.

He chuckles as Bruce protests the thought of moving and continues to stroke his hair in agreement, wrapping his other arm around him so he can rub his back.

"Five more minutes," he hums softly.

Yes, they can stay there. They can stay there as long as Bruce wants, really, because he's got his face buried in Tony's neck and he's curled up like a great big cat against his chest. And if he tries really hard, he thinks he can even get Bruce to purr. This is better than sex.

"How do you feel now?"
