AN: So, this chapter also got carried away from me and I just kept writing, but I really like how it turned out. Hope everyone enjoys this!

"All I have to say is I destroyed you on that training course," Sam announces as he walks into the common room and makes his way over to the fridge.

"I let you win," Bucky replies as he follows Sam into the room. Taking two bottles of water out of the fridge, Sam shuts the door and throws one of the bottles to Bucky who catches it easily. Sam grunts and takes a gulp of his water as he watches the man in front of him. Bucky opens his bottle and takes a drink of his own water as Sam recaps his bottle.

"Fine. Let's do it again and settle this," Sam offers with a raise of his brow and a smirk on his face. Bucky raises a brow before recapping his own bottle and giving Sam a smirk of his own.

"I have a better idea," Bucky replies causing Sam to furrow his brow in question. "We make our own obstacle course."

"Where?" Sam asks as he looks around them before settling his gaze back on the man in front of him.

"Here. We'll do it right here in the common room," Bucky replies as he sets his water bottle on the counter and already walking around the room and taking in everything.

"All right old man, what do you have in mind?" Sam asks as his gaze follows Bucky's movements around the room. Bucky disappears out of the room and fifteen minutes later comes back carrying multiple items in his arms. He drops all the items onto the table and grabs the rope and hook.

"First things first, we have to hook this rope onto the ceiling right…" Bucky begins to explain as he moves to where he's in the middle of the counter and table. "…here."

Bucky hands the rope to Sam and grabs one of the stools, pulling it over to the designated spot. Climbing up onto the stool Bucky begins attaching the hook to the ceiling. Sam watches as he cringes inside. Stark's going to kill us, he thinks but hands Bucky the rope when he reaches out for it anyways. Bucky attaches the rope to the hook and climbs down from the stool and puts it back in its spot. He instantly begins dragging the six chairs from the table and sets them in a line leading from the table to the armchair. He grabs the container off the table and hands it to Sam.

"Put that all over the counter but leave a spot at the end so we can get a good grip," Bucky explains and disappears back out the door again. Sam raises a brow before looking down at the container and sees it's wax. With a snort Sam opens the jar and begins to rub it all over the counter making sure to leave a spot free of the slippery substance at the end of the surface. He puts the cap back on the jar and looks up when Bucky walks into the room carrying a large work out ball.

"What's that for?" Sam asks with a raise of a brow and a smirk playing at his lips. Bucky shares the smirk and sets the ball near the second armchair before disappearing again. It doesn't take long for Bucky to reappear carrying multiple wooden boxes of different sizes and sets them up like stairs leading up to the counter. He pulls a stool over to be used as the last stair.

"All right," Bucky says as he claps his hands together and turns to face Sam. He begins walking down the path of the obstacle course as he explains what to do. "First, you go up the boxes to the counter. Slide down the counter, jump off the end, and grab the rope. Swing the rope and jump onto the table where we'll run to the other side. Jump onto the first chair where we'll step on the back of them and tip them to lead us to the next chair. Do that until you get to the end of the chair line and then step onto the back of the arm chair. Jump to the left onto the back of the couch and run down the length of it. Jump to the right onto the back of the other armchair and do a flip off it, landing on the floor. Then, finish with standing on the ball and log rolling it to…"

Bucky stops and moves over to an end table and opening the drawer. He shuffles through it before pulling out masking tape and walking back over to a spot on the floor. He rips off a piece of the tape and bends down to put it on the floor.

"…This spot," he finishes explaining before tossing the tape roll onto the couch and looking over at Sam.

"Let's do this then," Sam replies as he rubs his hands together in anticipation.

Bucky stands near the wall as he watches Sam jump from box to box to bring himself up to the counter. Sam slides down the length of the counter, thanks to the wax the two men put on it, and catapults himself off the counter and into the air where he grabs hold of the rope hooked. Using his momentum Sam swings on the rope and jumps onto the table. He runs down the table and hops onto a chair where he steps onto the back of it to tip it towards the chair behind him. Sam moves to the next chair to repeat the motion for the second chair in the line. He gets almost all the way through before he looses his balance and falls to the floor. Bucky lets out a laugh as he walks over and helps Sam up. Sam scowls and sends a glare to the line of chairs before setting them back up.

"My turn," Bucky announces before setting himself up at the beginning of the obstacle course.

"It's been scary Steve," Nat says to the man as the two of them walk down the hall towards the common room. "I keep walking in on the two of them doing some sort of shenanigans. I'm telling you, this is just starting. It's only going to get…"

A loud crash sounds from down the hall and Steve and Nat stop in the tracks and share a look. The two of them furrow their brows before looking back down the hall. Steve sighs, not really wanting to know what happened but knowing they should check it out in case someone is hurt.

"Sounds like it came from the common room," Nat says and Steve nods his head in agreement. The two friends quickly make their way down the hall and to the common room door where they stop in their tracks once again. Their eyes widen and their brows raise at the sight that greets them.

Sam is standing by the wall and grinning like a fool as he watches Bucky. Bucky has just leapt from a stool and onto the counter where he slides easily down it to the end. Once he reaches the end he jumps off and grabs a hold of a rope hanging from the ceiling. He swings the rope and does a flip into the air before landing on the table where he doesn't waste a moment before running the length of it. He jumps off the table and onto the first chair of a line. He tips the chair by standing on the back of it before moving onto the next chair. He swiftly repeats the action all the way to the end of the line before jumping onto the back of the armchair. Bucky springs himself into the air where he does another flip and lands onto the back of the couch. He runs to the end of it and flips onto the other armchair. The moment he lands on the back of the armchair he springs into the air again and does another flip and lands on the floor. He quickly steps onto an exercise ball and begins to log roll it towards Steve and Nat.

Bucky looks up and notices both Steve and Nat standing in front of him with arms crossed and eyebrows raised. Bucky freezes in his movement with wide eyes, except the ball continues moving forwards and out from underneath Bucky's feet. Bucky falls back and to the ground where he hastily does a break fall and rolls backwards to his feet.

"Uh… hey Steve," Bucky says with a grin which only grows when he notices a smirk play at the corner of his best friends mouth.

"I told you. Scary. It's already getting worse," Nat mutters to Steve who snorts and shakes his head. Nat takes in the whole room and sighs as she shakes her head. She looks between Bucky and Sam, fixing them with a look before continuing. "Stark's going to kill you both."

Bucky and Sam grimace while Nat mutters something else to Steve and walks out of the room. Steve sighs and looks between his two friends before looking at the obstacle course throughout the room. With a smirk, Steve lets his gaze move back to Bucky and Sam.

"Stark really is going to kill you," Steve says with a chuckle and a shake of his head. Bucky and Sam smirk and share a look.

"Awesome! An obstacle course! Can I join?" Clint's voice sounds from behind Steve and everyone turns to face him.

"Clint!" Nat's voice is heard from somewhere down the hall.

"No!" Steve reprimands Clint at the same time and grabs Clint's arm, dragging him out of the room, Clint's sputtered arguing being heard all the way down the hall.
