Early the next morning, team RWBY wakes to the sound of Ruby walking around. She is mumbling a few things about Yang and what she had seen the night before. Ruby paces around the room, and Yang soon gets interested in what she's all panicked about. Yang gets up, still in her pajamas, and pulls Ruby out into the hallway without saying anything to her teammates.

"Rubes, what is the matter with you? You're all panicked, you need to relax. How long has it been since you've orgasmed? Oh, wait.." Yang says quickly until she realizes what Ruby is panicked about. "This is about what I saw last night."

Ruby nods in fear. She's sweating bullets about this, her hair a little damp and her skin moist with sweat.

"Hey, I'm going to go ahead and say you do whatever you want. You know that I disagree with it, but I can't control you, sis. But, I promise, I'll be open to what you want." Yang rubs Ruby's back, giving her a hug.

Ruby pulls Yang's head down to her height and kisses Yang on the lips. "I promise, Yang, I won't mess around with Blake anymore. I just saw her t-touching herself, and I started touching myself, and we just got in a mess." Ruby blushes at how she has to say such words, and Yang laughs.

"Rubes, relax a little, ya prude. You have fucked two-thirds of our team, so just get used to talking about this. But, back on topic, if you need to get off, get me." Yang grins and kisses Ruby back, bringing her back inside the dorm. Weiss and Blake are already rushing around the room, getting dressed in their outfits and putting on makeup.

"Let's get ready, team!" Ruby says, trying to return back to her regular, relaxed persona.

In the depths of Mountain Glenn, the four of them set up camp in the center of the abandoned town square. They start a fire near the destroyed fountain and set up their sleeping bags in a circle around such. They decide on a rotation for the watch, and they agree that once they head to bed, Ruby and Yang will be on watch first, then Blake and Weiss. They will change every 3 hours until 'sunrise.'

During Ruby and Yang's first rotation, they sit together in a tower, Ruby leaning on Yang. Yang holds Ruby tight to her side, listening closely for Grimm. Crescent Rose is sitting behind Ruby, in the scythe position, ready for firing as a sniper rifle. Ruby and Yang talk about what they do together in private.

"Do you remember that one time when you were sucking me off in the bathroom back on Patch, and Dad was talking to you while I released my load in your mouth? I thought that was so funny." Ruby blushes, remembering the time like it was yesterday.

"Shut it, you dork. I thought Dad was going to come in any minute and see me giving head to my own sister." Yang laughs, kissing Ruby's forehead momentarily. She thinks about more times when they had fun.

Before Yang can talk, Ruby says another. "Do you remember when I was fucking you from behind, and we were watching the news in the living room? Dad actually asked me about the smell, if it was weird or something. I actually had to go masturbate to the thought of those events!" Ruby laughs hysterically before Yang goes dark red.

"Rubes, you know you should have just gone and got me! I love giving head to you," Yang says, laughing and hugging Ruby tighter. Ruby blushes.

"Well, if you like it, can you give me some right now? Thinking about this is getting me hard." Ruby slips her hand underneath her skirt and underneath her panties. She strokes her cock slowly before standing up and taking her skirt off for better access to it.

"Hell yeah, I'll even fuck you up here if you want," Yang offers, making Ruby blush hard from the absurd statement. Ruby places the thought in the back of her mind before getting her cock out, rock hard and standing tall at 9 inches. Ruby sits back down, and Yang pounces on Ruby's cock.

Ruby holds Yang off and pulls her up. "Can we do 69? I want to eat you out." Ruby smiles at Yang, and she nods. She pulls Ruby back onto solid ground and turns her to a comfortable position. Yang climbs onto a position where Ruby's python is right in her mouth, and her covered up snatch is right at her sister's mouth.

Ruby pulls Yang's underwear down like she is used to from years of living with her sister. She tosses them to the side, close to the edge of the building. Without waiting for Yang to start sucking, she pulls Yang's hips down to close the gap in between her mouth and Yang's pussy. She begins to eat her sister out.

Yang takes a deep breath through her moans and opens her mouth wide, moving her head all the way down her sister's shaft, swallowing up 8 inches instantly. Back on Patch, she quickly tamed her gag reflex to take all of Ruby's cock. What she's doing currently is child's play.

Ruby moans from the sudden surrounding of wetness on her member. She begins to rapidly flick her tongue at Yang's clit, making Yang shiver in pleasure atop Ruby's body. Ruby begins to slip a finger into Yang's entrance, while also sucking on her bud.

Yang begins to bob her head quickly on Ruby's enormous cock, going up and down the shaft. She leaves it coated in her spit, glistening with the little light in the underground city. Ruby moans from the feeling.

"Yang… I need to thrust into something… Can I put it in your butt?" Ruby pants out, knowing her orgasm is approaching.

It was a definite limit for Yang, vaginal sex, that is. She is saving herself for her partner, the one she'll be with forever. Her vaginal virginity is still intact, but Ruby and Yang have done anal loads of times, so they're okay with it.

Yang thinks for a minute with Ruby's cock deep in her throat. She takes it slow, considering a few things. She thinks about what she's told Ruby over the past week, and she pulls her head off of Ruby's cock. She pulls Ruby to her side.

"Listen, Rubes, you know how I'm saving myself for my husband?" Yang asks Ruby, holding Ruby by her waist, and stroking her to keep her going and not allow her to lose her erection.

"Yeah, that's why I put it in your ass." Ruby still shivers at the use of the word. She doesn't like it.

"Well, Ruby Rose, I want you to be my husband. Put your cock in my pussy." Yang looks at Ruby, completely behind her own idea. "You see, with our time bonding, by me giving you my oral and anal virginities, I feel we've gotten really close. I've started to admire you, Ruby. Recently, I can't stop thinking about you, and what you can do with your cock. I want you to be my partner for life."

"O-Oh. Okay, of course, sis." Ruby looks at her sister, unsure about the topic of being her sister's husband, but going along with it.

"Really? Thank you so much, Rubes. You're the best." Yang hugs her sister, kissing her passionately on the lips. She strokes her sister's shaft while doing such to get her going. Ruby moans out.

"Okay, now you're gonna fuck me hard." Yang falls back in bliss onto the floor of the 'room' they're in. Ruby sits up, realizing she didn't bring any condoms with her.

"Sis, I don't have any condoms... I don't want to get you pregnant," Ruby says, slowly taking one of her sister's overly large breasts into her hand and gently squeezing through the top her sister is wearing.

"Just cum inside me, I can get it out on our way back to camp." Yang grabs Ruby's ass, grinning when her sister goes as red as her namesake.

Ruby nods, still unsure of the topic. She positions her cock's tip at Yang's folds, looking into her eyes. Yang nods, and Ruby pushes in slowly. Her head pushes against a wall inside of her sister's vagina, and she proceeds to push right through it. Yang grits her teeth and clenches her fists in pain, her eyes flashing red.

"Yang, Yang, Yang, hold on," Ruby leans forward and pulls both of her sister's breasts out of her top. She begins to suck on one of the nipples, inciting a moan out of Yang's lips, relaxing her.

Ruby begins to push her cock deeper in, listening to Yang's moans of pleasure now that the pain has faded. Once Ruby has most of her cock inside of her sister, she begins to thrust in deep. She feels the tip of her cock kiss Yang's cervix, knowing that she's capable of repeating the process she did on Blake yesterday.

After 5 minutes of thrusting into her sister, kissing her sister's chest, and just listening to her sister's moans and dirty talk, Ruby's ready to blow her load. She begins to thrust harder, making the friction nearly pull the load out of her internal testicles.

She pulls all the way out and then thrusts in as hard as possible. She pushes through her sister's cervix and hits the back of her womb, making Yang's tongue loll out and her eyes go wide. Ruby blows her load deep within her womb, just holding it there for a moment, savoring the wetness.

Ruby pulls out, gently sticking her cock inside of her sister's mouth to wipe it off. She tries to make herself feel better about it, by saying to herself that she told her that she can do whatever she needs to feel better. By the time she has her cock inside of Yang's mouth, Yang wakes up and sucks her off until she's clean.

"Don't sneak up on me like that, little sister." Yang laughs.

"Don't pass out on me like that, my dear wife." Ruby laughs even harder.

The two sisters get dressed and grab their weapons. They do a full perimeter search for Blake and Weiss to have an easy time and then return to camp. They both kiss passionately, holding off their lust for each other until the next time. They wake the others, then return to bed, allowing each other some very wet dreams about their encounter.
