Cinnamon and Thread (слэш)

“It hurts most the first time, but you get used to it,” Bucky whispered. Steve jerked at the sound; it was Brooklyn, it was 1939, it was Bucky. “Bucky!” he tried to scream through the gag, fresh tears coming down his face. “You’re strong though. You’ll make a good asset. I’ll show you.”
“He’s secure,” Bucky said, voice toneless and mechanic once more
The chair lowered and Steve was screaming through the gag, still thrashing against the restraints even harder. Something lowered over his head and pressed against his face. He could not even jerk his face away, he was held too tightly. He met Bucky’s eyes; desperate, terrified as he tried to tell Bucky everything, tried to convince Bucky to stop this through eye contact alone.
The machine revved up under the chair. Bucky smiled down at him. Then all Steve knew was pain before darkness finally took hold of him. The last thing he saw was Bucky smiling. He looked the same.
