Here's chapter 12, 13 is mostly done, I ran into a case of writer's block for a bit otherwise this would've been out several days ago. RoosterTeeth owns all but my stuff.

It was the next day and Nathan was busy trying to block Yang's punches using the body of his pulse rifle. Her punches were getting faster and more difficult to block with some getting through. He tried to bring his rifle up to fire a burst but Yang sidestepped and shoved his barrel aside and socked him in the face dropping him on the ground in a cloud of dust. "I win again!" Yang said in triumph flexing her arms.

Nathan needed work on his close combat and relied too much on trying his best to keep his distance. "Owww." Nathan was opening and closing his hands to relieve the pain from blocking Yang's punches with his rifle.

"She really kicked your butt huh?" Ruby said who was watching the spar from the side along with Zwei who barked.

The three were training at a clearing near the house, Yang and Nathan's fight was first with the winner fighting Ruby. Nathan was somewhat relieved to not be fighting Ruby though he is used to her fighting style compared to Yang's.

"That was a decent warm-up but it's your turn Rubes." Said Yang cracking her knuckles.

Deploying Crimson Rose into its scythe form Ruby jumped in front of Yang. "Bring it!"

Nathan sat on the sidelines with Zwei to watch the two girls fight.

They squared off for a moment seeing who would make the first move until Ruby shot forward using the recoil of her rifle before swinging her scythe horizontally at Yang. Seeing this Yang ducked under her swing and fired a shotgun round from Ember Celica into Ruby but she quickly recovered using her semblance to evade her shots. Ruby appeared on the opposite side of the field and sunk the blade of Crescent Rose into the soil and sighted down her rifle. Yang realized her sister was trying to use her distance advantage with the sniper rifle and pelt her aura down from afar.

Yang started zipping closer, dodging what shots she can and eating others but still kept moving towards Ruby. The reaper withdrew her blade from the ground and counter-charged Yang striking out with her blade. The scythe connected skimming Yang's upper arm but she was able to land a series of quick shotgun punches with Ember Celica to Ruby's chest and stomach bringing her aura into the yellow.

"I win again! Nice try sis." Yang says helping Ruby off the ground.

"I don't think anyone can beat you with your semblance." Ruby said as she dusted herself off.

"You up for another round Nate or are you going to 'train' with Ruby?" Yang used air quotes when she said 'train' making him blush.

"I wanna fight someone I can beat!" Ruby said grabbing Nathan by the arm.

"Gee thanks Ruby." Nathan said sarcastically.

"You're welcome." Ruby answered back with a smile. Nathan was unsure if she realized he was being sarcastic or not.

"Well I'm going to go take a shower, have fun." Yang said with a wave as she started walking back to the house with Zwei.

"Someone you can beat huh?"

"Yup, and fighting you is more fun for me anyway." Ruby said readying her scythe.

"You want to go at it already? Doesn't your aura need to recover?" Nathan asked.

"I'm in the green now. Ready?"

"Uhh, yeah sure." Nathan said hefting his rifle.

Ruby dashed about twenty meters away from Nathan and got into a combat stance. "You can attack first."

Nathan leveled his pulse rifle from the hip and fired a fire dust grenade at Ruby who jumped straight up to avoid the incendiary explosives that torched the dirt below her. Quickly shouldering his rifle and aiming upwards he fired bursts of bullets trying to land a hit on the red reaper before she could bring the scythe down on him. He attempted to thump Ruby in the face with the muzzle of his rifle when she got but Ruby barely avoided the unexpected melee to make a diagonal slash across Nathan's chest followed by striking him in the right thigh with the bottom end of her scythe staff before shooting away.

The pulse rifle barked a long burst with Nathan dumping a copious number of bullets at Ruby. He fired so much he forgot to pay attention to his ammo counter until the rifle clicked empty. "Fuck!"

Dropping the empty magazine Nathan fumbled to insert a fresh one with Ruby speeding towards him with her scythe at the ready, a grin on her face. He just got the mag in and racked the bolt when she bopped him in the sternum with her weapon before firing a point-blank shot putting his aura into the orange.

"Whew, you're getting better Nate! Didn't think you would actually try to hit me there." Ruby said at his attempt at melee.

"It was just something I did on reflex, might be from some of the bayonet training I did when my mom and me found out I'm not all that hot at using melee weapons."

"That why you don't really make shifting weapons and instead use omni or combo weapons like your pulse rifle?" She said pointing at his rifle.

"Pretty much and also why I favor ranged weapons even if they put me at a disadvantage at close range."

"You mean like this?" Ruby says before hugging him.

"Hmm?"

"I just wanted a hug is all." Ruby said before letting him go. "Ready to head back and get cleaned up?"

"Yeah, have to clean my rifle first though. The bad thing about most of my weapons is they get very dirty pretty quickly." Nathan said holding up the pulse rifle.

"No point in taking a shower just to get covered in grime again. I guess I'll clean my baby with you."

The two traversed back to the cabin and retrieved their respective cleaning kits and began the process of breaking down and cleaning their weapons outside on the porch with Zwei running around the yard.

Their hands were blackened from the mixer of carbon fouling and gun oil, Nathan especially since he fired far more rounds than Ruby did. "Oum Nate! Your hands are all black!"

"Yeah they are." He said examining his hands before making a handprint on Ruby's left cheek.

"Hey! You're getting it on me!" Ruby said trying to push his arm away.

"I know." He replied before leaving black spots on her other cheek, forehead and nose.

"Ok, just for that you don't get to join me in the shower." Ruby said with a pout and looking away with her arms crossed.

"Wait what?"

Ruby quickly reassembled Crescent Rose and gathered her cleaning supplies and went inside. Nathan scrambling to do the same. He came inside and heard Yang. "How'd you get soot on your face?"

"From Nate, he rubbed it on me." Nathan got the feeling he might want to leave as soon as he entered the room the sisters were in.

"Nate…" Yang lightly growled. Ruby was standing behind her smiling.

"Yes…"

Yang punched him in the stomach. "Don't do that again."

"O..ok." Nathan uttered holding his belly.

"Good, see ya later Rubes." Yang said smiling at her sister before leaving.

"Why?" Nathan asked Ruby.

"Because you smeared gunk on my face you meanie."

"But did you have to get Yang to hit me?"

"Well no, she did that on her own." Ruby turned a shade of red under the soot on her face. "So you coming?" Ruby said walking up the stairs.

"To the shower?" He asked quietly following behind her.

"Yeah silly, we have to get cleaned up after all." She answered looking back at him.

The two entered the bathroom seeing that the mirror was still steamed from when Yang was using the shower.

"I hope she didn't use all the hot water." Ruby said as she turned on the water so it can warm up.

Ruby bent down and loosened the laces on her boots and removed them while Nathan watched her until she noticed the stare. "Start stripping you perv." She said jokingly.

He took off his boots as well along with the socks and his camo jacket and shirt. Ruby undid her corset and unzipped her top and removed them. Ruby turned away from him and slipped out of her black combat skirt and leggings, he moved behind her and hugged her from behind when she stood back up. "Hey."

"Hey Nate, get undressed. We can't be in here too long, they'll get suspicious when they don't see either one of us for awhile."

Nathan answered her by nibbling on her neck, turning the bitten sections of skin red.

"Nate stop….you'll leave marks." She protested but didn't make an effort to escape his hold.

He didn't care and kept at it. If Yang or Tai saw the bite marks well…he'll cross that bridge when he gets there. The shower water started to get hot as it started to steam up the small room. "S-showers ready."

"Uh-huh." Nathan mumbled before lightly biting her earlobe and groping her breasts through the red bra and one hand reaching down her body towards Ruby's red panties. He slipped inside and lightly rubbed her womanhood which made Ruby's whole body twitch before he pulled back out again and let her go. "Ready to shower."

"W-wait, you're stopping?" Ruby said disappointed.

"You said we should hurry after all." Nathan said as he pulled down his camo pants and boxers with Ruby staring at his now stiff member.

"W-well yeah its just…you were just teasing me weren't you?" Ruby said with a pout.

"Perhaps. Come on, it's clean up time. Remember your face is dirty." Nathan said stepping into the shower.

Ruby finished stripping and joined him in the shower. "You're so mean Nate."

"Well I w-wanted you after our spar but by the time I was in your p-panties I realized the rubbers are in the bedroom."

"O-oh, well you're still mean for teasing me."

"Yeah yeah, clean your face." He said swapping with her under the shower head so she can get wet and clean the soot off her face. "Besides, you know you loved it."

"And Yang and dad are gonna love seeing the marks you left on me." She said with a smirk as she lathed soap into her hair.

"Yeah, I'm not looking forward to that." He said scrubbing himself down.

"Don't worry." Ruby said then kissed him before moving to his neck to lick a spot before lightly biting him leaving a red spot. "There, a little bite from your cookie monster." She said tilting her head to the side with an innocent smile.

Nathan had worries that the mark on his neck would only make things worse.

Gripes? Bitches? Complaints? Let me know.
