Yang was sitting at home doing nothing, and for the energetic blonde this was a problem. Yang was always doing something, even if it was something she shouldn't be doing. The blonde reclined on the couch and, as she half focused on the TV, a thought popped into her head. "I wonder how Ruby's date with Weiss is going?" It had been a few days since Yang had taught Ruby how to dance in order to impress her princess. A devilish thought formed in Yang's head, causing her to grin evilly. "How about, instead of wondering, I go and see how it is?" The more Yang thought about this idea the better it seemed. Not only would she get to tease her baby sister about the date, she could also make sure that Weiss was following the rules Yang had set down when she had started dating Ruby. Yang decided to follow this plan of action, since it wasn't like she had anything else to do anyways. Blake was at her own house on account of wanting to peacefully read a book, something she couldn't with her rambunctious blonde girlfriend around. Standing up Yang stretched, standing on her toes and reaching for the sky. She could feel and hear her back popping. After that was done she took large strides to the hallway, trying to recall how to get to Weiss' house.

After she had the route sort of worked out in her head, she grabbed her motorcycle helmet and went outside to see her baby: Bumblebee. The glorious two-wheeled vehicle gleamed in the dying light of the day, the bright yellow paint the same color as her long hair. Yang gave the bike a loving smile as she threw her right leg over it, straddling the seat as she put on her helmet. Revving the engine louder than she needed to, Yang zoomed off towards Weiss' house, feeling the hum of the engine reverberate throughout her body. Only as she pulled up to the pristine house did the thought occur to her, "What if the door is locked?" Yang didn't always think things through. Deciding to go ahead anyway, and figure things out as she went along, Yang was pleasantly surprised to find the door unlocked

"Things are looking up, Yang" she said to herself as she opened the door and closed it much more loudly than necessary to make her arrival known. "RUBY, WHERE ARE YOU?" she shouted, wanting to start the teasing. As she walked into the house she heard voices down the hall, from what she assumed to be the bedroom. Before her mind could wander there, though, Yang shut her eyes to try blocking out the images. "We've been down that road already Yang" she admonished herself as she opened the bedroom door.

"Ruby how did the dancing…" her voice petered off as she opened her eyes. Clothes were strewn around the room and on the floor there were shirts, pants, panties… "Nononono," she thought frantically, not able to get her eyes to focus on the center of the room, "Can't be..." she kept repeating like a silent prayer. Making herself look up at the bed in the center of the room Yang saw a sight that she would rather have not seen. Ruby and Weiss were curled together under the blanket, and both looked terrified at the imposing blonde's entrance. What really set Yang off, though, was that she could clearly see that neither girl was dressed, and a familiar scent hung in the air. "Ruby… Ruby had sex… sex with Weiss." She thought this final coherent thought before she let her emotions take over, and she got mad.

"WHAT. THE. FUCK!" She screamed, further frightening the red and white haired girls.

"Yang…what...are...what are you doing here?" Ruby asked timidly. Yang turned her crimson gaze to her little sister.

"WHAT AM I DOING?" Her voice was still a shout as she continued her tirade, "I CAME TO SEE HOW YOUR DATE WAS GOING AND WHAT DO I FIND?" She left the question hanging in the air, so Ruby thought for a minute before offering up an answer.

"Ummmm… you find my date going really well?" The nervous sister asked with a sheepish smile, earning a sigh from Weiss and a glare from Yang. The blonde calmed down enough to focus her attention on Weiss.

"So princess, what were the rules I set down for you when you started dating my baby sister?" Yang practically growled the question.

"Actually, Yang, is it alright with you if we could… put our clothes back on before we continue?" Weiss asked timidly, afraid of what Yang's reaction would be. The intruding girl blinked several times at this question, as in her anger she had forgotten that the other girls were naked under the blanket.

"Uhhhh…. Sure, I'll wait for you two in the kitchen." she said, unusually reasonable given the circumstances.

After Yang had closed the door Weiss turned to glare at Ruby.

"How did she know about our date?" she questioned.

Ruby kept up her sheepish smile. "I just can't catch a break," she inwardly sighed. "Well, I asked Yang to teach me how to dance so I could impress you…judging by our current attire I'd say it worked," she muttered the last part under her breath, but Weiss still vaguely heard it.

"What was that?"

"Nothing, nothing," Ruby quickly backpedalled.

"Alright, so we know how she found us. Now what?" Weiss asked, not really to Ruby, but more as just a general thought she spoke aloud. Ruby still offered an answer, though.

"Well, I was thinking, if we dress fast enough, we can jump out the window and make a run for it before she notices, and we can start a new life in Mistral," she said, only partially joking. Yang was scary when she was mad after all, Ruby thought. Weiss didn't even deign Ruby's escape plan with a response.

"Just get dressed, you dolt. We'll deal with this problem somehow," Weiss said after an agonizing pause in which she had just glared at Ruby.

"Alright," Ruby said quietly, though she wasn't so cowed as to pass up an opportunity to fluster her girlfriend. When Weiss stood up to put her clothes on, Ruby gave the shorter girl's rear a little smack, causing Weiss to flush a brilliant shade of red. Turning around she saw Ruby just standing there with a playful smile on her face.

Weiss couldn't think of anything to say to that action, since her and Ruby were both standing naked after… "I'm still having trouble thinking about such things..." Weiss thought to herself. "Get dressed Ruby."

"Whatever you say."

They both quickly dressed after that, and cautiously left the sanctum that was Weiss' bedroom to go confront the threat that waited in her kitchen. Yang was sitting patiently in the kitchen. The red tint to her eyes had disappeared, leaving them the usual lilac.

"Please, take a seat you two," she said, gesturing to the two seats opposite her, acting like they were in her home and not the other way around. Ruby and Weiss exchanged nervous looks before sitting down. "Now, let's start where we left off. Schnee, can you tell me the rules I gave you when we had the older sister talk?"

"If I hurt Ruby you'll beat me up, if I cheat on Ruby you'll beat me up, if I mistreat Ruby in any way you'll beat me up," Weiss repeated back the rules she had been told months ago.

"Good, now which rule are you missing?" Yang asked, dead serious.

"There were no other rules you gave me," Weiss said, confused. Ruby had just sunk into her chair, trying to blend in and go unnoticed by her older sister.

"There was one other rule, an unspoken rule. Can you guess what that rule is?"

"Uhhh..."

"DON'T FUCK MY SISTER!" Yang roared, suddenly back to her angry state, cowing Weiss, but angering Ruby

"Yang, you don't get to decide what i can and can't do with my girlfriend." Ruby said with determination. Yang swung her gaze towards Ruby.

"Yes, I can. As your older sister it's my job to protect you."

"That doesn't mean you can decide my relationships," Ruby replied. Weiss decided this would be a good time to speak up.

"She does raise a valid point," was her calm and reasonable response. Yang just stared her down. "Point taken, I'll shut up now."

Ruby and Yang continued to stare each other down, with Weiss now doing what Ruby had done, just trying to blend in with her chair.

"Ruby you aren't old enough to make these kinds of decisions, so that's where I come in."

"No Yang, you can't treat me like a kid forever. You're going to have to let me make these decisions on my own." Yang looked thoughtful at this statement.

"No, you'll always be my little sister and it's my job to protect you."

"Yang, you won't always be there to protect me, you have to trust me," Ruby said quietly. Yang looked at her sister.

"I do trust you Rubes."

"Then act like it. You trust me and you have no reason not to trust Weiss. You have to let me grow up sometime."

"But what kind of example am I setting if i don't try and protect you?" Yang questioned. Ruby looked skeptical at this.

"Example? You regularly make references to having sex with Blake or you make sexual innuendos."

"I do not!" Yang protested. Ruby just gave her a dead serious stare.

"Yang what does the number 69 make you think of?" she asked, Yang just chuckled.

"Heh, it's a sex thing."

"My point exactly," Ruby said with a self-satisfied smile. Yang looked defeated as she slumped down in her chair.

"You're right; I'm not a good role model am I?" Yang said, more to herself than either of the girls in front of her. Ruby got up from her chair and leaned down next to her sister to give her a hug.

"You're a great role model Yang; you just need to be less protective."

"Alright. Though I think we need new rules." Yang said making the other two girls nod their heads.

"First, you can… you know," she started uncertainly, though she smiled when Ruby and Weiss both blushed and looked away. "But not when me or Blake are around. Preferably not at our house at all, but if you do, make sure you give yourselves enough time to finish before we get home. I don't want to walk in on that scene again," Yang continued, enjoying the embarrassment this conversation was causing Ruby and Weiss.

"Agreed," the two girls said after an awkward look between them.

"Second, I don't want to see you getting handsy with Ruby, save that for when you two are alone."

"Ruby is worse than me!" Weiss protested.

"Same goes for you Ruby," Yang said.

"Same goes for you and Blake," Ruby said. Weiss nodded at this, and Yang sighed but acquiesced.

"Alright, it is only fair that I follow these rules too," she said with a smile, happy this problem could be sorted out. "I'll tell Blake when I see her."

"And we want the picture you took of us on our first date," Ruby said, hoping she could come out ahead in this deal. Yang just laughed.

"Hahaha sis, don't push your luck. You're lucky that I haven't punched the heiress over there," she said while pointing at Weiss.

"Fine. Now, can you go home?" Weiss asked, wanting to get the intruding blonde out of her home.

"Fine, fine, I'm going," Yang said holding her hands up as she walked to the front door. "Just wait five minutes for me to get far away before you rip each other's clothes off again."

"YANG, JUST GO!" Ruby shouted as her face turned crimson from blushing.

Yang left with a big smile on her face. After a minute or so the two girls heard the sound of a motorcycle engine revving, then gradually get fainter and fainter as it went away. Ruby just looked at Weiss.

"Well, that went a lot better than expected."

"Indeed it did," Weiss replied. Ruby continued looking at Weiss, and an evil grin popped up on her face.

"You want to go and…" she left the last part unsaid. Weiss just flushed rose red.

"No," she muttered. "This girl will be the death of me," she thought, but then Ruby sat down next to her and leaned her head on Weiss' shoulder and smiled.

"Alright. I love you Weiss."

"I love you too Ruby." "There are worse deaths," Weiss decided with a smile.
