Okay. Steve knew cognitively what was going to happen at the end, here. But knowing and experiencing were drastically different things. One second Steve is enjoying the feeling of his hair being pulled and the way his name sounds on Bucky's lips. The next he gets a triumphant fire flaring through him, knowing he's accomplished his mission.

That, and a mouthful of...well. Bucky.

Steve doesn't quite know what to do, here. He hesitates a moment before deciding the only thing to do is swallow. It serves the double purpose of clearing his mouth and also letting him continue working Bucky until he is completely finished. Not knowing when that would be, Steve probably is on him a little longer than he'd like, but at least he manages to pull off, finally. Steve leans back on his heels with an exceptionally smug look on his face as he wipes his mouth.

"Not bad, I guess?" He has absolutely no idea that getting Bucky to come so fast might have potentially been a bad thing. His hands are still on his lover's hips, eyes still pitch black as the look up at him from his knees. His smirk grows by the second.

"Certainly didn't seem so bad from down here..."
