Tsukasa sat quietly at lunchtime, focusing her attention on the open door. She was patiently waiting for Kagami to come around the corner and join their friends, but she never did. Sis must be trying to keep her distance from Kona-chan, she thought. It made sense, since their relationship hadn't exactly ended on good terms. Fed up with waiting, she got up and walked out of the classroom with her bento box in hand, not telling Konata or Miyuki where she was going.

Just as she stepped into the hallway, Kagami nearly bumped into her, causing her to let out a gasp of surprise. She knew she needed to confront her sister, but now that they were face to face, she was too flustered to get the words out.

"Whoops, sorry," Kagami said under her breath. "I was wondering if you wanted to eat together."

Tsukasa nodded timidly. Considering what Konata told her, her sister's actions had an insidious air to them, but her mind seemed to go blank any time they were alone. They headed down the hall to a corner by the stairs where they were unlikely to be disturbed. What was she planning? Even as Tsukasa could feel her heart rate increasing, she couldn't find the strength to protest.

As they began eating, Tsukasa tried to keep one eye on Kagami, who didn't seem to be paying her any mind. With each bite, she did her best to build her confidence back up. The different ways this conversation could go flashed in her head like a movie. One possible outcome was that Kagami would deny everything Konata said and insist that she had no ulterior motive. Another was that she would admit to having an incest fetish and stringing Tsukasa along for her own twisted pleasure. The thought alone was enough to rile her up.

"Is something wrong?" Kagami asked. "Why are you looking at me like that?"

It was now or never. "Why did you ask Kona-chan to call you 'Sis' in bed?" The words burned in her throat as they came out.

Kagami nearly choked on her rice. "Tsukasa, you have to understand—"

"Understand what? Do you just get a kick out of seeing a little sister fall madly in love with you? Is that why you still haven't even said you love me back after everything we've done together?" She was already fighting back tears. "Please, I'm begging you. Just give me a straight answer."

"You've got it backwards!" Kagami protested. "I had those weird fantasies because of you!"

Tsukasa was dumbfounded. "Because of me?"

"The truth is I've always loved you, but I thought I'd never get a chance to act on my feelings. I boxed them up and tried to deny that they were there, but the first time Konata and I were intimate, I called out your name. She agreed to roleplay as you because we thought it would be safer than the real thing." Kagami began to tremble. "When you confessed to me, I tried to protect you by dancing around how I really felt. I don't want to see you get hurt because of me. I'm sorry."

Tsukasa's anger was short-lived. "Sis, I know I haven't always made the best choices, but I've had a lot of time to think about this one. Even if I get hurt, I'd endure it all if it meant getting to be with you."

Relieved that they had resolved their quarrel, Kagami put a hand on Tsukasa's shoulder and leaned in. No other words needed to be spoken. Tsukasa closed her eyes and kissed Kagami. Her tongue tried to make its way into her sister's mouth, but as soon as she got it in, they pulled away.

"Not right now. I think someone's coming."

The twins returned to their food just in time to not be seen by a fellow student coming up the stairs. Once he was out of sight, Kagami turned to Tsukasa and winked. "You'll get your chance," she teased.

As soon as school got out, Tsukasa wasted no time meeting up with Kagami so they could walk home together. Konata passed by them as they walked. She exchanged a knowing glance with Kagami before continuing by herself. Only the three of them knew what was going on just beneath the surface. At least, that's what Tsukasa thought. Shortly after leaving the building, she noticed a group of male students from her class looking at her and talking amongst themselves:

"Are those the Hiiragi twins?"

"Yeah, it would have to be. I saw them at a café yesterday and they were making eyes the whole time. Pretty sure I saw them hold hands, too."

"You think there's something going on between them?"

"I mean, just look at them! They're totally fucking."

This couldn't be happening. Tsukasa thought they had been discreet, but the rumors about their relationship were already starting. All eyes were on them. She felt like she could throw up from stress at any moment. Tsukasa looked to Kagami to see how she was reacting, but instead of saying anything, she grabbed her by the wrist and dashed off.

"Sis, where are we going?"

"Just run!"

Tsukasa didn't recognize the route they were taking. All she could do was let Kagami take the lead and keep putting one foot in front of the other. They weaved through a jungle of tall buildings, stopping only when they needed to wait for a light to change. By the time they got to their destination, they were both out of breath. Shortly after going inside, she realized that they had just walked into a love hotel. Kagami silently selected a room and handed enough cash for a two-hour stay to the clerk through a small window, allowing them to remain anonymous. The purpose of their visit was obvious enough: some much-needed privacy.

Once they were safe inside their room, Kagami heaved a sigh of relief. "I don't think we were followed," she said, still a little winded. The room was rather spacious, with a red and black color scheme. In the corner was a mini fridge stocked with various kinds of drinks. Kagami took out two water bottles and tossed one of them to Tsukasa. "Did you tell anyone about us?"

"Only Kona-chan," Tsukasa answered. "I thought for sure our secret would be safe with her." She lay on the bed and spread her arms and legs out, taking full advantage of how big it was. Compared to their beds at home, this was luxurious.

"Well, at this point, it doesn't matter." Kagami joined her and pulled her into an embrace. "We may need to stay apart until things blow over, but at least there's one place where I can have you all to myself."

Tsukasa ran her fingers through Kagami's hair. The sweet smell made her relax the tension she was carrying in her shoulders. "That's exactly what I want," she whispered. "I want to be just for you, Sis."

Kagami got on top and gave Tsukasa a mischievous grin before bringing her into yet another kiss. They wasted no time before allowing their tongues to reunite. Meanwhile, Kagami slowly crept her hand up Tsukasa's skirt until she found the front of her already-wet panties. Her hand moved back and forth, making her intentions as clear as the two plastic bottles that were now resting on the nightstand.

They had to break the kiss to take off their uniforms. With no need to worry about getting caught, they were free to be as brazen as they wanted. Tsukasa looked down at Kagami between her legs and giggled from excitement. She knew exactly what they would be doing for the next two hours, and she couldn't be happier.

"I'm sorry I didn't say this sooner, but I really do love you, Tsukasa. I love you with all of my heart."

Kagami was more than happy to take the lead since she had more experience. She was a gentle lover who used her hands and mouth to gradually unravel Tsukasa, speaking words of affection and encouragement all the while. Their first time was rough (and a little painful) because they were caught up in the moment, but now they had a chance to make things right. Tsukasa, for her part, wasn't subtle about how much she was appreciating the attention. Every touch was accompanied by a moan, gasp, or plea for more. Her whole body was ablaze with desire, and her voice became more and more desperate over time.

They still had about thirty minutes left when they were done, so they went back to cuddling after getting dressed. Kagami insisted on being the big spoon.

"Was it good for you?" Tsukasa asked. "You were the one doing all the work."

"You were fantastic," Kagami assured her. "Just making sure you felt good was more than enough."

Tears of joy escaped from Tsukasa's eyes. Through the good times and the bad, Kagami had always been by her side. At last, she was free from the secret that had tortured her since childhood. Instead of tearing them apart, they were closer now than ever before.
