Steve's trapped against Bucky, but there's nowhere else he'd rather be, even as Bucky keeps moving against him. He's a little oversensitive himself and he reaches down to get a grip on Bucky's hips to try to still some of the motion.

"I need a minute." The words are murmured into Bucky's ear, but even as they are, his other hand slides over Bucky's skin to wrap around his dick with smart fingers. The least he can do is help Bucky take the edge off. "I'm not going anywhere. Don't worry. I'm going to take care of you until you can't stand against for a week."

Even though it's a little too much for Steve, he thrusts his hips once to remind Bucky of exactly where he is.
