Ruby took another swig of her milk. By this point, it was about 80% chocolate syrup, but she'd really needed it since the Breach; over the past few days, she'd been forced to face the grim reality that bad things happen. Even though she and her team managed to minimize damages with the help of the rest of Beacon, people were still hurt and lives were ruined. The safety of the people was put at risk for the first time in a long time.

The thing that really stuck with Ruby though, was that she still had leagues to go in becoming a huntress. She got cocky, lost her weapon, and was captured. If it wasn't for her team and Oobleck, a surprisingly hardened hunter, she might still be a prisoner to the White Fang– and Roman Torchwick, the crime lord that had a grudge against her. Ruby hated to admit it, but she'd been scared these past few days and no amount of cookies and chocolate milk was helping. She had faced war, and she wasn't sure if she was ready. Bundling up in her cloak and a blanket, she tried to drown out her fear with cat videos to little effect.

Finding her first smile of the day in a cat playing with kittens, Ruby heard the door open. Yang came in, dripping with sweat and panting lightly. The reason why was displayed by her outfit, which was a pair of black booty shorts that Taiyang kept trying to get her to throw out and a bright yellow sports bra that she'd had what felt like three cup sizes ago; Yang's workout gear was small, not at all (or entirely) helped by her full figure. The blonde's bust was begging for cute boys to stare at the fabric strained against her skin, threatening to pour out from both the massive cleavage and the struggling underside.

In fact, likely due to Yang's jog and her general bounciness, her breasts actually did look like they were coming out; the miracle-working bottom band had begun slipping upwards, exposing the milky underside of Yang's boobs. This gap was further widened as the blonde stretched her arms overhead, breathing a satisfied sigh.

"Hey, Rubes," Yang said, ending her sigh by dropping her arms to her side. Though it was a small movement, her chest still rippled from the effects.

Comforted by her sister's presence, Ruby replied with, "Hi, Yang. I take it you enjoyed your workout?"

"I'd say so. Got plenty of looks, that's for sure~" Yang looked to a mirror, posing slightly. "Ah, that's probably why…" she said, noticing her excessive underboob and putting her fingers underneath her tits. "Damn… I think this top is finally failing me."

"Is that a problem to you?" Ruby asked, unsure of the answer.

Smirking, Yang sidled up to her sister. "Can you go ahead and fix it for me? As much fun as it'd be, I wouldn't want my girls to pop out when I'm benching. I might cause a scene~" she turned her back to Ruby and parted her hair.

"I don't know if that's a yes or a no…" Ruby went behind Yang's back and began adjusting her top; even pulling it a little bit was a struggle against her chest, but she managed to secure it for the moment. Knowing Yang wouldn't, she reached around to pull down the top so it'd fully cover her breasts. However, as she stretched, Ruby slipped on her blanket.

"Woah, hello!" Yang giggled, finding Ruby's hands gripped firmly around her breasts. Her little sister had used her bust to prevent herself from falling and was now clinging on for her life.

"Wah! Oh, my gosh! I'm sorry!" Ruby gasped, letting go of Yang's boobs and retreating to her blanket fort. "I screwed up again and fell!"

Yang blew out an annoyed breath. "Again? What did you screw up, exactly?" The blonde's face switched from amused to annoyed, clearly put off by the phrasing.

Ruby began twiddling her fingers, still nervous and jumpy about everything. "Well, I still–"

"Are you still on about last week?" Yang said, angry. "You did great! We saved the city together! You took on an entire terrorist group!"

"Y-Yang, I got caught and–"

"–And helped stop the biggest Grimm invasion in history? Cuz that's what you did."

Struggling to find her confidence, Ruby shrunk. She wasn't used to being scolded by Yang; she hadn't since they were kids. If anything being the leader meant she could finally criticize Yang's poor choices without retribution; more than once she'd decried the blonde over focusing on flirting over training.

Seeing her increasing volume wasn't doing wonders for her sister, Yang sighed. "Look, I'm sorry for yelling at you. Sure, things weren't perfect, but we did awesome for a couple of noobies! And you, Fearless Leader, did awesome, too!"

Soothed by her sister's words, Ruby smiled for the second time. "I'm just scared I won't get better… I got caught and I didn't–"

"–Shut up, sis. We're gonna go train some more, we're gonna do some missions, and we're gonna kick all the ass, you got it?"

"But what if–"

"Get over here," Yang said, blindsiding Ruby. The blonde pulled her sister into a tight hug, shutting out all of her negativity for the time being. Her sisterly-motherly instincts kicked in as she began gently swaying and petting Ruby's hair, calming her. She hadn't held her like that since they were little and Ruby needed her older sister. Her maternal instincts had always been incredibly strong, seeing as she had been forced to be the mom; Raven left a poor impression, but Yang had always tried her absolute best to mirror Summer's love as best she could with from the times she remembered. Even before Ruby could walk, she'd done her best to cradle her when she was upset. The time where she took Ruby out in the wagon only to be attacked by Grimm had caused her to never her leave baby sister's side; this was the first she would have left Ruby on her own, but she surprised everyone by making it into Beacon. On one side, that meant she was always there to look after her, but that also meant she still expected to be looked after.

"We're going to be the best team at Beacon, and we're going to punch everyone who says otherwise."

Though she was a leader at heart, Ruby was still a younger sister. Though old enough to go to war, her personality left a lot to be desired when it came to growing out of needing Yang. Her loss certainly didn't help her case, as she was used to winning. Even Yang, who got pouty and irritable upon losing a game of cards took her hits better; Ruby was always a prodigy and losing her first major battle had hit her incredibly hard.

Still lacking her usual combat-confidence, Ruby said, "But–"

"–And we're going to scythe anyone who says otherwise." Yang brought Ruby closer to her chest, pleased at her correction despite the grammar issues.

Resigning herself to her fate, Ruby nuzzled deeply into Yang's chest. Ignoring the sweat, she could hear her sister's heartbeat, instantly calming her down and letting her know that she was there to protect her. Though Yang was her sister, she was also the closest thing she had to a mom, having lost hers before she was really conscious of it; it was only instinctual to find comfort in a mother figure's heartbeat, and Yang's pillowy breasts didn't exactly hurt.

Feeling the need to share her love, Ruby acted on other instincts. Before she could stop herself, she pursed her lips and pressed them against Yang's chest, kissing a spot on her massive breasts that was free from her top. Finding herself close to the massive cleavage, Ruby continued kissing Yang's breasts as she found comfort in the soft skin. A bit caught up in the moment, Ruby closed her eyes and lost herself to Yang holding her against her chest, feeling the blonde delicate fingers brush against the back of her head, brushing lightly through her hair.

As Ruby became aware of her actions, she attempted to move away from Yang, only to pause. As she refocused on the world around her, she was filled with a noise she wouldn't expect; unmistakably, Yang was letting out a long, satisfied sigh. To further the idea that she was gaining extra enjoyment out of the situation, the blonde unintentionally drew Ruby closer.

No part of her wanting to object, Ruby felt Yang's hand coax the back of her head forward, pushing her further into her breasts. She was met with the sweet-smelling skin of the blonde's large, soft, pillowy breasts. Finding only comfort, Ruby felt inclined to continuing rewarding Yang with kisses; as she pressed her face further into Yang's breasts, Ruby graced them with gentle pecks, tasting the warmth and scent of a comforting hug. Her cheeks squished up against the squishier boobs, the skin meeting skin enveloping her in heavenly peace.

If nothing else, Ruby was definitely calmer.

Rather abruptly, Yang disengaged the hug. Ruby found herself free of her sister's breasts, realizing she hadn't taken a breath in minutes; she'd been too absorbed by the lilac-scented lotion the blonde used, though her mind was also preoccupied with how blissful it was between her boobs. Now given time to think, Ruby's fears were lightened, but now she was stuck wondering what just happened.

Yang, clearly not wanting to talk about the awkward boob-hug that just occurred, scurried off out of the dorm with a quick, "Gotta crush Sun's deadlift record. Be back in a bit." It was clear that she was slightly out of breath, and not from her jog. Her flustered face was the last thing to exit the dorm, leaving Ruby in her blanket fort.

Ruby sighed. Though she now had most of her confidence back, her fear was replaced by confusion. Yang was her sister! And kind of her mother? Mother figure? She has a figure, that's for sure– Wait! She was doing it again. Ruby was now split between her loss against the White Fang and the very clear memory of being between Yang's boobs.

Falling back into her bed, Ruby felt a lot less self-doubt in herself. Yang's calming had done wonders for her, though it also brought a slew of strange new feelings. Regardless, as Ruby took a swig of her chocolate milk, she found it tasted a lot better now that she wasn't moping.

Upon finishing a video about a cat sneaking up on a toy, Ruby decided to swing herself out of bed. Encourage by Yang's message (among other things), she grabbed Crescent Rose and made for the training field; it was about time she decided to get stronger and stop whining about it.
