When Bucky heard the sounds of a struggle with the soft grunts that were undoubtedly Steve's, he gave a slightly annoyed sigh. Steve never listened to his suggestions to try and stay out of trouble and after tonight Bucky wouldn't be here to get him out of it. The uniform he was wearing was spiffy and all but it also served as a reminder that he wouldn't be here to protect Steve for who knows how long. A little voice at the back of his head mentioned that this may even be his last night ever with Steve but he brushed it off.
Right now he was just going to go and get Steve out of whatever mess he was in now so they could head out to meet their dates. Following the sounds to the alley behind the movie theater, he walked towards the end, preparing for whatever fight the guy may give. They were more in his sight now and he just had to... he stopped in his tracks. This wasn't another of Steve's fights.
Steve was pinned to the ground, pants at his ankles, being thrust into by his attacker, a pocket knife held to his throat. Sounds of protest slipped out of his mouth and he repeatedly tried to push the guy off him but he had him held tight.
Bucky barely registered whatever mocking words the guy threw at Steve as he climaxed inside him. Bucky's mind was overcome by a red haze as a pitiful whimper escaped Steve's mouth as his attacker pulled out and roughly pushed him to the ground with a cruel laugh which was abruptly cut off when Bucky grabbed him with an angry growl and threw him at the wall.
"Get off on hurting people smaller than you, huh?" he shouted, punching the other man in the jaw, sending him sprawling on his back on the ground, knife slipping out of his grasp. Bucky dropped down on top of him and pinned him down as he threw more punches, yelling and cursing in between each blow. He grabbed the fallen knife and pressed it to the man's neck, pressing hard enough to draw a thin trail of blood, mixing with the flow coming from the man's nose.
"Give me one reason why I shouldn't kill you right now." he snarled. He would end up locked up for a long time if he did this and was found out but right now it seemed well worth it.
He was only stopped from slicing the blade through the bastard's throat by the weak call of his name from Steve. It was enough to make him completely forget about what he wanted to do to the man he had pinned down and he immediately left him to rush to his friend's side. Steve had pulled his pants back up but was obviously very battered up and wounded despite trying to hide the pain he was in. Bucky heard the attacker get up and scurry out of the alley but right now he had to focus on Steve.
