Luna stepped out of her room, still feeling anxious. She hurried to the bathroom to get ready for campus. However, upon entering, she saw Aria completely naked. Aria's large, round breasts stood out with beautiful nipples, while her smooth, hairless skin looked incredibly enticing. Even her genitals were visible, adding an erotic touch to the scene. It seemed Aria had just taken off her clothes and placed them in the laundry basket.
Luna was mesmerized by the extraordinary sight. Aria smiled and suggested they shower together. Aria emphasized that soon they would be sisters, and it wasn't unusual for sisters, especially girls, to bathe together. "Seriously? If we shower together, I might lose control," thought Luna, panicking and blushing deeply.
"I-I'll go first, you bathe first," Luna stammered. Aria looked disappointed, but as Luna tried to leave, Aria suddenly hugged her from behind. Luna panicked even more, her mind racing with thoughts as Aria's naked body pressed against her. Aria pleaded for them to bathe together, saying she always dreamed of chatting with a little sister, even if only once.
Luna understood, since they were both only children. Luna might have wanted an older sibling or a younger one, just as Aria wanted a little sister. Swallowing hard, Luna said, "Uuuh... Fine! Let's bathe together! Just let me go!"
Aria was thrilled by Luna's response and released her hug. Luna was still blushing, not expecting to show her naked body to anyone, especially Aria. With mixed feelings, Luna began to remove her baby doll nightware. Her body trembled as she lowered the shoulder straps slowly, trying to cover her already hardening nipples with her arms. But the satin fabric eventually fell to the floor, revealing her beautiful, mature breasts.
Aria looked at Luna with a flushed face, her eyes fixed on Luna's naked body now standing in front of her. Luna covered Aria's face while shouting, "D-Don't look!"
Feeling very embarrassed but trying to stay strong, Luna was led by the enthusiastic Aria into the bathroom. They walked slowly to Luna's family's modest bathroom.
The bathroom wasn't very big but was comfortable and fully equipped. There was a clean white sink with a mirror above it, a small shelf on the right filled with soap, shampoo, and lotion. In the left corner was a small bathtub with a floral curtain. The bathroom floor was made of plain white tiles, always cool to the touch. There were bright-colored towel racks and a soft light blue mat in front of the entrance.
Aria walked ahead of Luna, humming her favorite song. Her graceful, relaxed movements made Luna admire her, her gaze fixed on Aria's perfect naked body from behind. Every curve and muscle appeared so harmonious. In their nude state, Aria's body's beauty was undeniable, her smooth skin and perfect proportions exuding extraordinary charm and elegance.
Standing in front of the shower, Aria turned and suggested Luna wash first with cold water. Luna stood shyly before Aria, her face red and her eyes occasionally glancing at Aria's body. Aria smiled, then turned on the shower, making Luna yelp as the cold water hit her body, causing her to shiver. Aria chuckled at Luna's reaction.
Aria then went to the bath supplies, crouching to grab a bath sponge. She put soap on the sponge and gently squeezed it until it produced soft foam. Luna felt uneasy for some reason. Aria returned with a smile, holding the foamy sponge, and asked, "May I wash your body?"
Luna quickly refused, "I-I can do it myself!" Aria looked disappointed, her cheeks puffing out cutely like a child whose wish was denied. Luna felt a bit guilty seeing Aria's expression but tried to stay strong and not appear too weak.
Luna took the bath sponge from Aria and began washing every inch of her body, ensuring no dirt was left. Then, she rinsed her body again with the cold water from the shower. Shivering slightly from the cold, Luna glared at Aria and said, "Now it's your turn, I need to use the shampoo." Aria nodded slowly, showing a disappointed face for not being able to wash Luna's body.
After both finished cleaning themselves with cold water, they entered the bathtub together. Luna's family bathtub wasn't very large but was big enough for two adults to fit comfortably. As the warm water surrounded their bodies, Luna and Aria felt a sense of comfort spreading through their pores.
Aria began talking as she wanted, discussing various things about herself—her job, her current living situation at her mother's house since her parents' divorce. Meanwhile, Luna remained silent, occasionally giving short responses. Luna still wasn't used to starting conversations with others except for people she trusted like Maya and her mother.
After soaking in the bathtub, they slowly got out and began drying their bodies with soft towels. Their smooth skin gleamed after being soaked in warm water. Their wet hair added an elegant touch. Aria carefully dried her hair with a towel while Luna focused on drying other parts of her body.
Once they were sure their bodies were dry, Aria and Luna wrapped themselves in large, warm towels. Luna's towel was light blue, matching the bathroom mat, while Aria's towel was pink with a floral pattern. With relieved hearts and refreshed bodies, they walked out of the bathroom together.
However, before Luna could step further, Aria called out to her, "Thank you for fulfilling one of my wishes of having a cute and sweet little sister."
Luna blushed hearing this from Aria, but her smile faded when Aria added with a pout, "Ah. Although, I'm a bit, just a tiny bit disappointed for not being able to wash Luna's body."
Hearing that last remark, Luna felt annoyed. She wanted to say something but held back and chose to rush to her room, grumbling to herself, "Such a pervert, speaking so casually like that!"
At campus, in class, Maya saw her friend looking depressed. Maya asked what was making her feel so down, "Luna, what's wrong?" Maya asked. Luna looked at Maya, tears welling up in her eyes, then quickly hugged Maya. Surprised, Maya became more curious and said, "What happened to you?!"
"I can never get married! I've shown my naked body to that person!" Luna replied, her voice breaking in her hug. Maya was shocked to hear this confession. Her body was shown to someone else? Maya couldn't believe what she had just heard.
In Maya's mind, she felt jealous because since entering middle school, Luna always refused to bathe together. Her mind replayed those rejections, creating a feeling of unfairness that squeezed her chest. Maya was upset that Aria got to see her friend's mature body without her knowing. Maya's eyes started to tear up, but she held back, remembering that Luna needed support now.
"Luna, calm down. We can talk about this more later. I'm here for you," Maya said gently, trying to comfort Luna who was still hugging her tightly.
"Ah but, you didn't do 'it,' right?" Maya asked nervously. Luna wiped her tears, not understanding what Maya meant. Maya quickly grabbed a novel and showed her a paragraph. Luna read it slowly, then her face turned bright red, she closed the book and said, "How could I do that!!" Maya finally breathed a sigh of relief, knowing that Luna's innocence wasn't taken by Aria. "Thank goodness. I was worried you might have done something inappropriate," Maya admitted, sounding slightly relieved. Luna just sighed and shook her head, not believing her friend's concern.
Luna then recounted the events of that morning, about how Aria begged her to bathe together. "And guess what? I don't know what she was thinking wanting to wash my body with a bath sponge!" Luna said angrily, remembering the bathroom incident.
Maya wasn't listening to Luna's complaints; her mind was imagining Luna's mature body—her smooth and soft skin, with perfect and proportional curves. Luna's slim waist contrasted with her full hips, creating an alluring silhouette. Luna's firm and round breasts, which Maya had glimpsed while they changed in the locker room, made her heart race in her imagination. In her fantasy, they were both naked, washing each other's bodies and entering the bathtub with Luna sitting in Maya's lap, facing each other. As their lips got closer, Maya was snapped out of her daydream by a sharp flick from Luna on her forehead.
"You're daydreaming about me again, aren't you?" Luna asked, pouting. Maya rubbed her slightly sore forehead, "S-sorry."
