It's almost too much, and he hasn't even been knotted yet, he feels so overly sensitive, but he doesn't stop moving, trying to control himself enough to allow his alpha to take control. As strong as Bucky is, there's a big part of him that wants to submit, especially now, when his heat is making it nearly impossible to think straight.

"God, I want your knot." He's still rocking in time with Steve's thrusts. "Please, Stevie."
