Golden Freddy x Duke (fnaf x Oc: Yaoi/bondage)

Duke started to stir awake, letting out a yawn and stretching. Something wasn't right. He looked at his wrists to see they were tied together. His ears perked and he let out a sigh, having an idea on who did this.
"Gold!" He yelled. He tried to break the rope with his strength, but to no avail besides a small whine from it. He heard the door creak and close. Gold had walked in, a wide smirk on his face. Duke glared at him.
"Untie me. You know I don't like being tied up." Duke said, a bit of a stern look on his face. Gold walked forward, being inches away from the bed.
"And why is that puppy?" He smirked again. Duke only seemed to get a but more frustrated.
"I just don't, untie me now!" Duke barked at him. Gold only chuckled and got on the bed. Duke glared at him again, but this was cut short by a yelp when Gold got ontop of him.
"Gold...get off..." He said, his muzzle starting to get red.
"Make me." Gold snickered. Before Duke could respond, his lips were met with Gold's. He froze up, not really knowing what to do. Gold pulled away and licked his lips.
"G-Gold....what the hell..." Duke stammered.
"Quiet puppy. I know you want this." Gold said, putting a hand on Duke's chest. His heart was racing. It took a second for Duke to notice that they were both very aroused. Gold eyed his erection lustfully.
"Hm, so you really are as big as I thought." Gold said, a bit of his eagerness showing in his voice. Duke was shifting his eyes up and down. Gold noticed and looked down at his own erection.
"Oh, you like what you see huh? You've been more quiet than normal." Gold said.
"I'm not used to being tied up...." Duke blushed.
"Well be a good dog and turn over for me will ya? We'll both get some good out of this."
Duke obeyed and turned to his stomach. He lifted his upper body and rested his arms on the bed post, arching his back and flaunting his ass at Gold. Gold smirked and held his hips, lifting Duke's tail over his shoulder. Duke shuddered with anticipation. This wasn't the first time Gold had suprised him with sex. But this was different. Duke had very little control over the situation. Gold was one of the few at the park who could compare to Duke's strength. His thoughts were interupted when he felt Gold shove his cock inside him.
Duke gasped loudly as his body tensed a bit. Gold bit his lip and let out a small grunt.
"Damn puppy...your ass is so tight..." Gold groaned. He thrusted his hips back and forth, holding Duke closely. Duke moaned as his toes curled. He almost forgot the feeling of Gold's thick member. He pushed his ass back into Gold's hips with every thrust, making him go deeper. This earned a few moans from Gold and wrapped his arms around his waist. Duke's member was throbbing, dripping with sweet smelling precum. Gold thrusted faster, letting out more moans of pleasure. Duke's walls squeezed tightly around his member, pumping it roughly with each thrust. He started to tense up, his teeth clenching.
"Blue...I'm about to blow..." He warned. Duke didn't answer, his body rocked back and forth, his moans being accompanied by the creaking of the bed. Gold let out a lustful moan as he pumped his seed inside of Duke. The blue wolf jolted and moaned as well, shivering from the feeling of the warm liquid filling him. Gold pulled out and chuckled a bit.
"You didn't cum yet wolfy? You last long..." Gold snickered a bit. He crawled infront of Duke, bent over on all fours. We wiggled his plump ass and smirked.
"Why don't you shove that big ole stick in here? It's only fair that you get to cum." He said. Duke looked down, his member only an inch away from Gold's ass. He scooted up and thrusted his hips, penetrating Gold. His hands were still tied to the bed posts so all he could do was thrust. Gold gasped and put his hands on the head of the bed, arching his back. He was already overwhelmed, for he had underestimated the size of Duke. He moaned loudly, his legs fidgeting like he had no control over them. Duke huffed and panted, his tongue hanging out. He already began thrusting harder and increasing the pace of his thrusts.
Gold's tongue flopped out his mouth as his eyes rolled up. He could only moan as he was being pounded silly.
"D-Duke...fuck...nng!" He moaned and grunted loudly. Duke moaned and thrusted even harder. Gold tilted his head back in pleasure. Duke started to tense up as his knot began to swell. He did one more hard thrust and shoved his knot it, cumming hard. He howled in pleasure, bucking his hips with each spurt. Gold's eyes widened, trembling from the feeling as he went limp, panting tiredly. He was drooling from pleasure, his mind blank. Duke looked down and smirked slightly.
"Who's the boss now?"
