"Okay, so for now, we'll place the electric piano here. If there's anything else you want, just let me know right away. I'll get you whatever you need."
"Got it. But remember, if you ever want to set me free, you can do so anytime."
"Hehe, what a funny joke."
It wasn't a joke, though. Sigh, I feel completely drained. In the end, I couldn't convince my sister. After that, she kept asking me what else I wanted in the room. It seems she intends to keep me confined here for quite a long time. But even though she said that, I couldn't really think of anything I wanted, so after a long while, we only decided on placing a piano in the room.
"Staying indoors all the time isn't good for your health. You need to get some sunlight regularly, or you'll become inactive. The room might get a bit cramped, but I think we should also set up some exercise equipment."
"Yeah, I guess."
I responded half-heartedly. I mean, the problem would be solved if she just let me out of the room, but I guess that's not happening. Do whatever you want. Even though I haven't taken a single step outside, I feel utterly exhausted.
"...I suppose during the day, you should stay in my room. If I put away the bed, there will be more space, and we can place various things there. We need to get a lot ready. —Oh my, it's already so late. Time flies when I'm talking with Kaya. How about we take a bath now?"
"A bath? That actually sounds nice."
I really need to relax, at least in the bath. Plus, my feet are starting to feel stuffy from wearing these restraints all day, so I'd like to freshen up. Surely, she'll let me take off the shackles while I'm in the bath. After she removed the shackles from both my legs, my sister carried me to the bathroom.
"You'll take them off for the bath, right?"
"Of course. I'll remove them now."
With a click, the shackles were undone. Finally, my legs were completely free. They weren't painful, but they were certainly uncomfortable, so I was relieved when she took them off.
"Alright, I'm going in, so you can leave now."
"No, I'll be joining you."
"Why? Since it will be troublesome if you died in the bath. Honestly, I don't even want to let you go to the bathroom alone, but I'm allowing it for your sake."
The thought of bathing with my sister at this age felt odd, but I really wanted to get in the bath, and if I argued about it now, she'd probably insist on coming into the bathroom with me every time from now on. So, reluctantly, I agreed. Thankfully, the bath was spacious enough for both of us. I quickly undressed, waited for her, and we got into the bath together. As I was about to wash my hair, as usual, my sister stopped me.
"From today onwards, I'll wash you, Kaya."
"I can wash myself."
"Please, let me wash you. We haven't done many sisterly things together until now"
Confinement doesn't seem very sisterly to me, but if that's what she wants, fine.
"Okay, I understand."
I sat on the bath stool and waited for my sister to wash me.
"How does that feel? Nice?"
"Yeah, it feels good."
She gently washed my hair, carefully running her fingers through it, which felt surprisingly pleasant. She occasionally asked if she could rinse with the shower as she continued. Naturally, she moved on to washing my body as well.
"No, sister. It's fine if you wash my back, but I'll wash the front myself. —Hey, are you listening? Hah..."
A strange sound escaped me when she suddenly touched my chest.
"Kaya, you're still so small all over. It's cute, though. I wonder if you'll hit a growth spurt after you turn 15."
I couldn't even react to her casual comment. I'm not used to being touched by others, so it felt ticklish as she thoroughly washed every inch of me.
"Come on! I said I'd wash myself! Now it's my turn to wash you, so get ready!"
As payback, I pretended to wash her, but really, I just tickled her. Before long, it stopped being about washing, and we both ended up in a playful tickling match. After a while, we looked at each other and burst out laughing together. Had we ever played around like this before? If everyday life could be like this, maybe this lifestyle wouldn't be so bad.
After the bath, I was taken back to my room and shackled again. We talked until I got sleepy. She told me stories from her past that I hadn't heard before, and I shared mine as time passed. Maybe I won't be able to go to school again tomorrow, but for some reason, that didn't bother me as much anymore.
