It's a powerful thing as he watches the Soldier start to lose it all. The fight, the rebellion, the hold on whatever fragments are there. It's a powerful thing, knowing that all throughout, he's still thrusting deep inside of him, owning him. He watches the Soldier he knows getting wiped nearly clean, the shift in that gaze and demeanor taking hold.

He feels as the convulsions wrack the Soldier's body and brain, leaving him slack and pliant under him. Everything loosens, and Rumlow is left to fuck into him relentlessly with nothing standing in his way. He loves it and hates it, but he knows what kind of power he hopes to yield with these results.

"It's okay... it'a alright. I've got you. I've always got you. I'll always take care of you. Just do what I say, follow my every word and I'll protect you." He purrs into the Soldier's ear, fingers digging in tight at his collarbone. "You're mine. Remember that. You'll always be mine." He drives it home with another deep thrust, and then he cries out, spilling into the Soldier, slicking his entrance with each thrust. When he does so, he gives a nod to the tech to continue, riding out his orgasm.
