"Big sister, do you want to take a bath together?"
Alisa stood at the bathroom door, wrapped only in a towel, and looked at Maria, who was lying on the bed reading a manga.
The house they had been living in had been completely destroyed, leaving a huge hole. It would definitely take more than a few days to repair. Although their family had bought them a new house to live in, moving would still take some time.
So, after discussing it, the two sisters decided to stay at the Tohsaka residence for another week and move to their new home over the weekend.
For now, they were staying in a guest room. The room was quite spacious, almost like a hotel suite. It had a large bedroom with a sofa, a fireplace, and a tea table, as well as a separate study and a bathroom with a large bathtub.
"No, Mr. Kaito said he might come over tonight," Maria replied.
"What's he coming here for?" Alisa instantly became alert.
"Of course, for treatment," Maria said, tilting her head and smiling. "Do you want to join, Alisa?"
Treatment?
Alisa recalled the pleasure she had felt during the electric therapy that day. She couldn't help but tighten her thighs slightly, her eyes showing a hint of desire.
But she said, "No way! Big sister, how could you even think of doing something like that a second time?!"
"Huh?" Maria tilted her head, still smiling at Alisa.
Although it was her usual, somewhat innocent smile, Alisa couldn't shake the feeling that her sister had seen right through her.
"Alisa, are you jealous?"
"Jealous?! Why would I be jealous of him?! What are you even thinking, big sister?!"
"I-I'm going to take a bath!!!"
Alisa's face turned bright red, and she started rambling, even slipping into Russian at the end. Without waiting for Maria to respond, she hurried into the bathroom.
"My, Alisa is so cute," Maria said with a smile, gazing at the closed bathroom door.
She rolled over on the bed, facing upward, and stretched her arms toward the ceiling.
"Thank goodness Mr. Kaito isn't a bad person."
"Are you talking about me?"
"Ah?!"
Maria was startled and instinctively covered her chest as she sat up.
She looked over and saw Kaito Sora standing by the bed.
"Big sister?" Alisa's voice came from the bathroom.
"It's nothing! I just almost fell off the bed while rolling around," Maria replied.
"Honestly, big sister, you're so careless," Alisa said, completely fooled by Maria's excuse.
Maria then turned to Kaito and whispered, "Mr. Kaito, you're so mean. You scared me! And you didn't even knock before coming into a girl's room."
"I didn't want to keep you waiting," Kaito said.
He had just returned with Medusa. After explaining Medusa's situation to Rin Tohsaka, he had assigned Medusa to protect Rin. With Medusa around, even if a Servant were to attack Rin during the day, Medusa could buy time using her abilities in the imaginary space, allowing Kaito to return and join the fight.
As he spoke, Kaito noticed Maria's furtive behavior and asked, "Why are you acting so sneaky?"
"Well, it's because of your heroic rescue at noon today, Mr. Kaito. It was so dashing that you stole little Alisa's heart. If she found out you were giving me treatment, she'd probably run off to a corner, crying and muttering about us in Russian," Maria said with a grin.
"Is it really okay for you to talk about your little sister like that?"
"So, should we call it off?"
"No!" Maria quickly replied, spreading her arms in a completely defenseless pose.
With her natural, innocent expression, she said seriously, "I'll try my best not to make any noise. But my endurance isn't very strong, so I hope you'll be gentle, Mr. Kaito. Not as rough as last time..."
She paused, then added, "Although I did like it when you were rough with me."
One of us definitely has a dirty mind.
Kaito sat on the edge of the bed and, with practiced ease, placed his hand on Maria's plump thigh.
"Should I take off your clothes, or will you do it yourself?"
"Mr. Kaito, you're so mean," Maria said, her face flushed and her breathing slightly labored.
"At noon, it was to thank you for helping Alisa. But now, I haven't agreed to let you touch my leg."
Despite her words, Maria only put up a token resistance before closing her eyes.
Understanding her intentions, Kaito began to undress her.
Then, he placed his hand on her thigh and activated his lightning technique. As his hand moved, he gently stimulated the meridians and acupoints throughout her body.
"Mr. Kaito, you're so bad. Last time, you only touched my shoulder," Maria said through gritted teeth, her face covered in sweat.
"This is better for your health."
"I don't believe you."
Although she said that, Maria's only form of resistance was to cover her mouth.
Soon, she grabbed a nearby blanket and bit down on it.
Her feet stretched out, her toes curling tightly into the bedsheet.
After a while, Maria began waving her hand toward the nightstand, like a drowning fish struggling for air.
"What's wrong?" Kaito paused his treatment and looked at the nightstand, where a phone was sitting.
"Do you need the phone?"
Maria weakly nodded.
Kaito handed her the phone and stopped the treatment for the moment.
Maria fiddled with the phone for a bit, and soon a soft melody began to play—a Russian song that Kaito didn't recognize.
"Mr. Kaito, you can continue now," Maria said, placing the phone aside.
She looked at Kaito with her usual gentle, almost saintly smile, despite her flushed and exhausted face.
Kaito didn't respond, but the lightning surging in his palm was answer enough.
After a while, Alisa's voice came from the bathroom, sounding confused.
"Big sister, why are you suddenly listening to music?"
She sounded a bit groggy, as if she had just been woken up by the music.
Maria tried to suppress the trembling in her voice.
"Did it wake you up? Should I turn it off?"
"It's fine," Alisa replied sleepily.
She didn't seem to notice the odd tone in Maria's voice.
"I shouldn't sleep any longer, or I won't be able to sleep tonight."
There was no response.
Alisa lay in the bathtub, enjoying the warm water and the gentle massage from the jets. After a while, she finally came to her senses.
Hearing the loud music playing outside—seemingly at full volume—Alisa didn't think much of it and started chatting with her sister about the music.
But there was no response. It was as if Maria had fallen asleep.
"Big sister? Big sister?"
Alisa called out a few times.
"Honestly, how can she fall asleep with the music so loud? Big sister is such an airhead."
Just as Alisa was about to get up and turn off the music to avoid waking Maria, a sudden scream came from outside.
"Ah?!!!"
"Big sister?!"
Alisa was startled and immediately stood up from the bathtub.
But she had stood up too quickly. Combined with the fact that she had been sitting in the bathtub for a long time, she felt dizzy and had to hold onto the edge of the tub to steady herself.
After a moment, she got up and called out her sister's name as she prepared to go to the bedroom to check on her.
But just as she reached the door, Maria's weak voice came from inside.
"I-I'm fine. Mr. Kaito is giving me treatment."
Alisa paused.
If Kaito was treating her sister, then it was probably fine. After all, she had also experienced his treatment once, and it had been the most comfortable experience of her life.
But why did her sister's voice sound like she was in pain? The treatment wasn't supposed to hurt.
"Alisa, do you want to join us?"
Hearing this, Alisa immediately gave up on the idea of going out.
"I-I don't want to!"
Alisa walked back to the bathtub and sat down.
"Big sister, how can you be so loud? And when did Mr. Kaito even get here?"
"He arrived while you were sleeping. Are you sure you don't want to join? It feels really, really good."
"No way!!!"
"That's a shame. You can come out anytime, Alisa~"
"I'll wait until you're done."
"Tehe, little Alisa is so shy."
"Big sister!!!"
Maria looked up at Kaito, who was now very close to her.
Her eyes were filled with resentment, and tears even began to form. Her usual innocent expression was gone.
"I never said I'd repay you like this, Mr. Kaito. You're so mean."
