"Big Sister Yuyuko, why are you looking at me with such a strange expression?" Kars felt a surge of instinctive nervousness as Yuyuko stared at him, and he asked her with confusion.
"Because you're giving off a very nice scent and feeling, Kars. It's strange, I didn't feel this way when we met before." Yuyuko said, moving closer to Kars. That comfortable, warm feeling became even more pronounced, causing her to hug Kars and deeply savor the long-lost warmth.
"It feels so good…"
"Good? Is it the energy in my body?" Kars quickly realized the cause was the energy in his body. As he pressed against Yuyuko, he not only felt a sudden chill but also the sense that his energy was being absorbed.
"Mmm~ I feel better and better." Yuyuko felt the change in her body and grew increasingly fond of this sensation, even absorbing it more greedily.
"Big Sister Yuyuko, this is making me uncomfortable…" However, compared to Yuyuko's expression of pure comfort, Kars felt quite distressed. He was unaccustomed to the feeling of his energy being absorbed and struggled in Yuyuko's embrace, wanting to move away to prevent it from continuing.
When Yuyuko heard Kars, she suddenly came to her senses and realized her state was a little off. She released Kars, but as the enjoyable sensation disappeared, Yuyuko was momentarily unable to adjust. She even felt a desire to hug Kars again.
"Ha… this feeling really takes some getting used to…" The feeling of his energy being drained reminded Kars of the time during the Scarlet Mist Incident when he first tried to use his power against Reimu Hakurei, and his entire internal energy was sucked dry. Although the current controlled and slow absorption was still uncomfortable compared to that swift drain, it was within his tolerance level.
"Here are the utensils. Huh? Kars, what's wrong? Your face suddenly looks unwell." Youmu Konpaku, returning with the utensils, saw Kars's sudden change in expression. She stepped forward and asked with concern.
"Nothing, maybe I'm still a bit unaccustomed to the Netherworld." Kars shook his head and replied. He couldn't easily explain what had just happened, so he blamed it on his discomfort with the Netherworld.
"I see. Well, that's normal. This is the world of the dead, after all. Even as a vampire, you might feel a bit uncomfortable, especially since you're a unique kind." Youmu Konpaku didn't suspect anything, believing Kars was just genuinely uncomfortable. She then took out the cake, placed it on plates, and served it to Yuyuko and Kars.
"Ooh~ it's so delicious!" Youmu Konpaku took a bite and immediately smiled. The cake tasted wonderful not only because of the craftsmanship but also because of the meaning it carried. Seeing the sweet messages written on the cake, Youmu Konpaku felt her taste buds and her heart filled with sweetness.
Yuyuko next to her seemed slightly different than usual. Although she was still happily eating the cake, her expression lacked the usual joy she showed when eating. Youmu Konpaku, currently immersed in her own happiness, didn't notice Yuyuko's demeanor, but Kars, who felt Yuyuko's gaze, felt a slight stiffening of his expression.
He had a feeling things were developing in a rather delicate direction.
After they finished the cake, Youmu Konpaku collected the plates and left the room to prepare some tea, leaving only Kars and Yuyuko again.
"Big Sister Yuyuko… could you please not do that?" Kars asked, feeling nervous as Yuyuko approached him again.
"Kars, just let me hug you for a little while longer, alright? You saw it yourself, didn't you? I wasn't satisfied just now, to the point where I didn't even have an appetite for food."
"No appetite…" Saying she had no appetite while eating most of the cake was a statement that was hard to believe.
"And if you want anything to happen with Youmu, I'll pretend I didn't see anything."
"You don't need to do that at all… Ugh!" Kars, hugged by Yuyuko again, felt the softness of her breasts and the sensation of his internal energy being absorbed. A feeling of weakness began to creep in.
"It feels like coming back to life, it's truly wonderful." Yuyuko loved this unique sensation. She lowered her head to look at Kars, who was leaning against her chest feeling a bit tired, and gently stroked his head.
"I'm sorry for suddenly putting you through this. I feel a little embarrassed."
"It's fine… it's not to the point where I can't move at all." Kars got up from Yuyuko's embrace, and suddenly, a cute gasp escaped Yuyuko's lips.
"Ah~ What… what's happening? My body suddenly… mmm~" The familiar sound of flowing water came from Yuyuko. Kars watched Yuyuko slump onto the tatami mat, then clutch her lower abdomen, her body trembling.
"It's… happening again… aah~" The continuous, multiple orgasms made Yuyuko's body tremble even more violently, and her expression became incredibly erotic. Her eyes were watery, and as she moaned, saliva dripped from the corner of her mouth.
When it finally stopped, Yuyuko lay on the tatami mat, constantly panting. Her pale thighs were exposed to Kars's sight beneath her lifted skirt. The mysterious area was faintly visible, drawing Kars's attention. Due to the angle and how it was partially covered, it gave the impression that she wasn't wearing anything underneath, making Kars want to take a closer look.
