Welcome back, everyone, to Ruby's Regression! We've seen Ruby go from a closeted adult baby to a babied little sister by Yang, but there is still one teammate we haven't seen react to our little diaper girl: Weiss. And with that, I present: Chapter Three!

Chapter Three

When Ruby woke up later that afternoon, she awoke with a strong push from her bladder. As she started to get up to use the bathroom, she remembered everything that transpired yesterday, and smiled. With pleasure, Ruby slowly released her stream into her diaper, the hissing sound it made as it struck the diaper arousing her incredibly. Eyes closed and blushing furiously, Ruby sat there for over a minute, pee streaming into her diaper. When the stream began to subside, Ruby opened her eyes to the face of Weiss, who was sitting ather computer desk, cheeks redder than Ruby had ever seen.

"Oh! Weiss! Um…..hi?" She stammered. This isn't exactly the best way to introduce my new lifestyle thought Ruby as she tried to sink back into her blankets.

"Hi…..don't worry, Yang told me everything already." She spoke, causing Ruby to sigh. "Do you, um…..need to be changed?" She asked. Suddenly, Weiss's blush had become the more subtle of the two, as Ruby's blush quickly multiplied itself.

"Um…..I can change myself….you really don't have to if you don't want to…." She muttered, her face now pointing towards the ground.

"No you can't! Don't think Yang didn't tell me about your punishment! Now you can either assume the position on the ground in front of me or you can spend the rest of the day in a damp diaper!" She said firmly. Ruby's submissive nature took over and in seconds she was laying on the ground waiting for Weiss. Weiss, meanwhile, grabbed a fresh diaper, baby powder, and a wet wipe, moving her armful of supplies next to Ruby. Suddenly, now that the situation was in front of her, the shy Weiss came back out.

"Feel free to tell me if I'm doing something wrong…..I never really changed a diaper…we Schnees are potty-trained incredibly early to support independence. Winter was potty-trained by 6 months and I was potty-trained by a year...the only diaper changing I ever did was on a doll I had as a little girl…." She fumbled as she removed Ruby's diaper. With Ruby's pussy now on full display for the heiress, both of their cheeks deepened in their hue as Weiss took a long look over, eyeing the intricate features, something that didn't go unnoticed to Ruby. Slowly, Weiss ran a wet wipe across Ruby's pussy, the cold paper arousing her as it dashed along her nether regions. Making sure to take extra care, Weiss meticulously wiped the area, inserting the wipe into every fold and even wrapping it around Ruby's incredibly erect clit, eliciting a moan from the younger girl. Weiss giggled with this, slowly relaxing to the idea. She then applied the baby powder to her leader's lower lips before wrapping the diaper snuggly around Ruby's posterior, firmly securing it.

"Thanks, Weiss…..you're really good at that!" said the little diapered girl, sitting up to hug the Heiress.

"Your welcome, and thank you. Um...so...may I ask a question?" Weiss spoke modestly.

"Of course!" Replied Ruby, now standing up to walk around, the crinkling noise following her with each step.

"Are they uh..um….comfy?" said Weiss, clearly embarrassed by her need to ask.

"Yea! It's kinda like a pillow is wrapped all around you!" Piped up Ruby.

"Could I um….maybe...if it wouldn't be too much trouble…..try one on?" She stammered, quickly rotating her gaze away from Ruby. Ruby grinned, she knew there was a reason Weiss was so easily accepting of the situation!

"Yeah, sure! Just come lay in front of me." She said. Weiss slowly walked over to Ruby, descending to her knees and then her back as she laid in front of Ruby. Ruby ever so gently pushed up her skirt, revealing the pale white panties underneath.

"Thanks…." mumbled Weiss, "I never really got the opportunity to wear them as a baby, and can't even remember when I did." As Weiss babbled on, Ruby focused on her task at hand, removing the Heiress's panties, revealing a pair of well-shaven, white lips. Along with Weiss's bareness, Ruby noticed the sufficient amount of pussy juice exuding from Weiss's cunt. Ruby snickered quietly, it was clear that the prim and proper Weiss was just as much of a diaper fetishist as Ruby was! Hoping to tease Weiss, she grabbed a new wet wipe, applying it to the ice queen's pussy, causing a loud moan to release from Weiss. With only a single wipe, Weiss's juices squirted out, landing on Ruby's arm.

"Oh my dust, I'm so sorry! I'm really sensitive and…." stuttered Weiss, only to be interrupted by a kiss from Ruby. Their lips, like two lovers reuniting after years of a long-distance relationship, locked lovingly together, brushing away the inhibitions of the world in exchange for hormones. As Weiss got over the shock, she began to embrace Ruby, the kiss becoming more intense and erotic as it went on, with Weiss even throwing in some tongue, licking against those soft, pillowy lips.

As the two kissed, Ruby's hand naturally dropped the wet wipe, touching Weiss's pussy without the constraint of the cloth. Weiss moaned into Ruby's mouth, the younger girl now rubbing the snow angel's dangerously sensitive clit as a puddle formed underneath the two of them. With more and more pleasure being centered around her, Weiss's mind began to blank, and her hips began to buck her lower lips to Ruby's hand. This sent Ruby into a sexual frenzy as she entered the Heiress's core with a single finger, the damp cavern contorting itself around the digit. Weiss's moans got louder as Ruby thrusted in and out, vibrating Ruby's lips and tongue as they wrestled with the ice queen's. Soon, Weiss was visibly panting into Ruby's mouth, about to cum, and quickly pulled herself from Ruby's lips.

"Ruby! Ruby, oh fuck! Ruby I'm gonna cum! I'm gonna….kyaaahhhh!" she screamed as she squirted once more, coating Ruby's hand and lower arm in pussy juices. As the wave of pleasure slowly lessened, Weiss's breath slowed down. Overcome with her after-orgasm glow, the Heiress looked up to her lover, their eyes locking to one another, as though they were trying to work out what just had happened.

Ruby, hoping to avoid the awkwardness of the after-sex talk, went back to her earlier task, powdering Weiss and placing the diaper snuggly around her.

"Well….um….thank you…." Weiss stammered, her breath still a little out of sync. She stood up, her legs attempting to buckle, but her diaper holding them firmly in place. She then walked back to her computer, crinkling all the way, until she sat down, a large squishing noise following.

Ruby just sat there, unable to comprehend what just happened. I just had sex with Weiss, she thought, I don't know how to continue from here! What if she wants to talk about it? What if she thinks I'm weird? What if she accuses me of rape?! Ruby calmed herself, more than willing to push all these questions out of her mind. Ruby then grabbed her scroll from the desk, smiling at Weiss, who fortunately smiled back, and sat down next to her on the floor. Propping herself up on the desk's side, Ruby and Weiss silently began to do their homeworks, neither willing to talk about what just happened. But Ruby could tell that this quiet was not an awkward quiet, but more of a content quiet. They were both relaxed, and Ruby wouldn't have had it any other way.
