Chapter 52 - 23. Family first (Part 4) [R-18]

I admonish myself for getting caught up in these misunderstandings.Yuki takes the sponge and starts to lather my back. She uses just the right amount of pressure, and it even feels like I'm being washed from the bottom of my heart."... Shun-nii, does it hurt? Are you okay?"In response to Yuki's concern, I reply with a trembling voice, "I-I'm okay." It's a very common response, like something a young sibling would do, but because we're grown-up siblings, it seems to lead to naughty thoughts.Yuki then removes the sponge from my back. Just as I was about to regret my answer, wondering if I'd gotten it wrong, I heard the sound of foaming again. It felt like she was lathering with her hands."Excuse me, in front..."Yuuki then comes to the front of me. Her hands are lathered, and I understand that my prediction was correct, but at the same time, I can't hide my excitement at having Yuki naked so close to me.Yuki bent over, so I could see the cleavage of her modest breasts. I think I have a strong attachment to breasts, and I get excited easily. So my erection got stronger, and Yuki's eyes were drawn to my dick for a moment."... Yes, Shun-nii, I'm going to lather you up from your shoulders, okay?"However, she shook me off and started washing my upper body. Since she had washed me once before, I was able to endure the act itself. Although she was silent, there was no problem until she lathered up my upper body and legs.But that was as far as it went."Well then... I'll wash this too...?"After saying that, Yuki, of all things, began to massage my scrotum. I shivered, but I was beginning to feel pleasure, and I couldn't stop it. I knew it was a bad reaction for an older brother, but all I could do was cry out, "Uuh." Yuki slowly checks my expression and the feeling of my scrotum, then gradually extends her fingertips to my hard cock."Yu-Yu... there..."In an instant, the air was turning lewd. I knew it wasn't right to let Yuki do this, but in the end, I couldn't resist the pleasure.So, Yuki's fingers tightly wrapped around my erection, decorating my cock with the foam of the body soap."... it's kind of slippery and feels weird..."Yuki continued to move her hand, with a look of deep interest. Since coming to this world, I've had a few handjobs, but I still can't get used to it. What's more, the body soap added a sensation I'd never had before.Having my cock handled by a girl, a beautiful girl, a sister, I was approaching my limit. He knows that his balls are getting full from being squeezed."Ah, Shun-nii's twitching here... is he going to come...?"Yuki looks up at me, but her hands don't stop. Despite her cuteness, all she's doing is servicing my dick.Her slender fingers, which have such dirty thoughts, are making my semen rush up to the tip of my penis in no time. It's clear that I'll soil her if I keep going like this, but the semen is relentlessly rushing up."Yuki... I'm sorry, but I'm coming! I'm coming, uuh!"The milky white liquid gushed out. I know it's too soon, but I can't stop myself from ejaculating."Ah, Shun-nii's...!"The semen that spurted out of my dick flew onto Yuki's forehead and hair, who looked shocked. Her beautiful skin and black hair were gradually covered in white from my filthy desires, and the situation caused my semen to be released for a long, very long time.After confirming my ejaculation, Yuki, who looked shocked, closed her eyes and bathed in the white semen. As the momentum weakened and the semen dripped onto her cheeks and around her mouth, her cute face turned lewd."Hmm, Shun-nii's semen..."By the time I had finished, Yuki was sticky in many places. And yet, with her eyes closed, she even looked like she was smiling with the corners of her mouth turned up.Still, I felt like I'd done it again. I'd given in to my desires again and made Yuki satisfy my sexual needs. Even though Yuki had started doing it, she was still my little sister."Sorry, I couldn't control myself... I'm sorry Yuki."When I apologized timidly, Yuki opened her eyes and answered in a puzzled tone."Why? I was the one who started touching Shun-nii's, so there's no way I'd feel disgusted."She looked at me while licking the semen off her mouth. She tasted my milky liquid with a casual atmosphere, as if she was licking ice cream."I'm glad if Shun-nii felt good... but maybe I should wash your hair a bit. Hehe, Shun-nii, I think you should wash it."Yuki suggested this while she was lightly washing my dick in the shower, and I timidly agreed. And then, in front of me, Yuki sat with her back to me.I felt bad that there was a cloudy liquid on her hair. I washed it off carefully, but quickly, in the shower, but my hands were still clumsy."Hehe...Today is a special day, the day that Shun-nii shampoos me."As I lathered Yuki's hair, she spoke to me in a happy voice. But I only massaged her scalp slowly, worrying whether this was the right way for a girl to wash her hair."It must have been about seven years ago...The last time we took a bath together, Shun-nii wasn't very enthusiastic. But I think he looked away from me the whole time because I was having fun."I listened to Yuki's story while moving my hands slightly. She spoke in a slightly sad tone, as if she was remembering."Since then, Shun-nii hasn't spoken to me much. We only really rarely had conversations... so maybe I was just a little, just a little lonely."What kind of status must I have had to refuse to talk to her, even though she wanted to? Even in this world, I'm not sure I'm good-looking enough to be proud of."But lately, Shun-nii has been really nice! Up until now, he'd given off the vibe that he didn't even want to talk to girls... but now, he seems to be getting along really well with the girls around him."She'd been speaking cheerfully up until that point, but Yuki's voice started to tremble a little as she continued."... so..."  "...So when I saw Shun-nii being hugged by Yamamoto-san today, I felt jealous. Even though I told him to get along with Asagi-san, maybe I was just jealous. So I have to get closer to Shun-nii and get closer to him. We live in the same house, so there are things that only I can do...So I suddenly asked him to take a bath..."Yuki continues, talking about how kind I am to not refuse."Hey, Shun-nii, compared to Sasai-san and the others, I'm not cute or mature, but I want you to play with me just as much...no, even if it's just a little, I want you to play with me."Yuuki tells me how she feels about me with her back to me.I don't know what to say in response, but I shouldn't lie or reject her."...If you want, Yuki, I'd be really happy if we could go out and have fun together, not just talk...Is that okay...?"When I told her that, Yuki turned her face towards me and smiled at me from behind. That smile was both cute and mature, or so I thought. She gave me such a jewel-like smile. As a man and as a brother, I couldn't be happier."Thanks, Shun-nii...Yes! Now, let's get your hair washed!"Yuuki seemed a little embarrassed, but he urged me. The black hair, which had been washed off with the bubbles and had been cleaned of semen, felt good to the touch, and even seemed very sacred."Hehe, then, next, please take good care of my body."With that, Yuki slid the bottle of body soap towards me. But she didn't hand me the sponge. Even though it was right in front of her.I wonder if it was okay to touch my sister's body directly with my hands. We had been having such a serious conversation, so I wonder if I could resist something that stimulated my sexual desire like that."C'mon, Shun-nii... I want you to wash me."With that, she said, forcing the body soap into my palm. After all, she wanted me to wash her with my hands. In that case, I had no choice but to go along with it.But I mustn't get the wrong idea about becoming close to her as a sister. With that in mind, I started to lather Yuki's back.
