"Sister, why do you look so tired?" Flandre looked at Remilia, who was sitting in the chair, looking fatigued and unwilling to move, curious about what she had been doing.
"I'm not tired, Flandre. Just don't worry about me right now, alright?" Remilia waved her hand, telling Flandre to go play and not disturb her rest.
"Okay." Flandre nodded. Rather than dwelling on why her sister was like this, it was better to go play with Kars.
Remilia watched Flandre run off and let out a small sigh of relief. She then placed a hand over her skirt, pressing and lightly rubbing the area beneath her abdomen. The lingering sensation from earlier still caused a physical reaction.
"What Patchouli is doing really is getting worse. Did she even start with that kind of thing? But now, I myself…" Remilia took a deep breath to manage her physical reaction. While mentally scolding Patchouli, she thought about her own current state. She, too, couldn't help but be involved in these matters now. If things continued this way…
"Well… I guess it wouldn't be so bad…" Remilia felt that perhaps this wouldn't be such a problem after all. Even if it progressed to that final step, she could always… they could always just get married, ensuring the continuation of the pure Scarlet bloodline.
Thinking this way, Remilia felt much calmer inside. She no longer felt that these matters posed any significant obstacle.
"Kars, let's play a new game!"
Meanwhile, in the Great Library, Flandre had pulled Kars in for their usual kissing game. However, the kissing game wasn't providing much entertainment for Flandre anymore. She felt there was a much more fun game to play: the one she and her sister had played that night.
"A new game?" Before Kars could ask what it was, Flandre pulled down her top, exposing her chest. Kars immediately understood.
"That's right! And Kars, you really like doing this when you sleep. You bit Flandre's chest very hard before, but this is much nicer than kissing. It's just a little uncomfortable when I wake up. See, it's still a bit red here. So Kars, you need to use the other side today."
Kars hadn't expected Flandre's "new game" to be this. Seeing her lean in, asking him to bite her breast, left him momentarily stunned.
"What's wrong? Does Kars like this side better?" Flandre was confused by Kars's lack of reaction, wondering if he preferred the side he had bitten before. But this side felt a little more sensitive now. After a brief hesitation, Flandre decided that since Kars liked the other side, she would let him use that one. She was the one who had suggested the game, so she would just have to endure it slightly.
"Kars, come here."
Flandre held her breast out in front of Kars and waited. Kars saw the tip of the nipple right in front of him. He opened his mouth, took it in, and began to gently suck. He was no longer conflicted about biting his aunt's chest; Patchouli had told him his Aunt Remilia didn't mind, and now his Aunt Flandre was asking him to do it, so there was no need to worry.
Flandre's adorable noises were very clear in the quiet surroundings. This noise soon attracted someone very familiar with this area.
"You two are playing this secretly here?" Koakuma walked in and saw Kars and Flandre's actions, a seductive smile on her face. Her sudden appearance startled both Flandre and Kars. Before they could speak, Koakuma continued.
"Can I join in? We could play an even more interesting game, you know."
"What game are you talking about, Koakuma?" Flandre was immediately intrigued by Koakuma's suggestion.
"This game is much more exciting than the one you're playing now." Koakuma walked behind Flandre and picked her up. She then spread Flandre's legs, exposing the white panties with the bat pattern inside.
"It's right here."
"Really?"
Before Flandre could be sure, Koakuma slipped off her panties and hung them on her foot. Kars thought Koakuma was going to use the method he had learned from Patchouli, but instead, he watched her use two fingers to gently open the folded flesh.
"Now, Kars, just like before, you start on this spot."
"With… with my mouth?"
"That's right." Koakuma replied matter-of-factly, then brought Flandre closer to Kars's face. "See, isn't it cute and lovely? Don't you want to take a bite?"
Koakuma's tempting voice and Flandre's moans, stimulated by Koakuma's handling, slowly drew Kars in. When his warm breath touched the spot, Flandre felt a ticklish sensation.
"Bite down now, gently bite down for me~"
Under Koakuma's gaze, Kars did as he was told and bit down. Flandre immediately arched her back and cried out. The unfamiliar sensation stimulated Flandre's mind, causing a strong physical reaction.
Seeing Flandre panting and exposed, Koakuma wanted to kiss her mouth to increase the sensation, but Flandre turned her head away.
"Flandre… only plays with Kars…"
This rejection surprised Koakuma. She quickly changed tactics, licking Flandre's earlobe, which also intensified Flandre's pleasure.
Finally, Flandre completely collapsed in Koakuma's arms, too weak to even move a finger, her chest heaving rapidly.
"How was that? Wasn't that much more fun than what you were doing before?"
Flandre, too exhausted to speak, gave a faint affirmative murmur. This game had definitely provided a much more intense and captivating feeling than their previous one.
"And I want to play a round, too, Kars." Koakuma lifted her skirt, revealing she wasn't wearing anything underneath, allowing Kars a clear view of the liquid running down her thigh.
"But I have to take my aunt back to her room." Kars looked at Flandre, who was slumped against the bookshelf. Leaving her there to go play with someone else didn't seem right.
"Aww—why would you do that!" Koakuma was greatly disappointed. She was the one who had started the whole thing, only to end up getting nothing herself! This was simply too unfair!
