"Hey there, Fumibo! Don't hold back—eat up!"
"Thank you for the meal!"
Our families have been close since forever—my dad works for the president of a transport company. I was practically raised by them as a kid, and even after growing up, I'd get invited for dinner at least once a week. After Dad's accident, those visits increased to two or three times a week.
The president (or "Uncle," as I call him) and his wife must really care about me. I'm endlessly grateful for that.
"How's Kazuki doing?"
"Ah, same as always. Every time I visit, he just keeps apologizing. Like, dude, you're my dad—you don't have to be so formal with me."
"With you being his only child, he probably feels awful about burdening you. Man, if only Fumiko were still alive..."
"Dad, don't bring that up in front of Fumi-kun."
Fumiko was my mother—she died giving birth to me. I know her face from photos, but since I never actually met her, I don't feel any real familial connection, as bad as that sounds. Honestly, the president and his wife feel more like family to me than anything.
"I'm home~! Mom, I'm starving~!"
"Oh, welcome back, Himari Nee-chan!"
"Ah, Chi-kun's here! How's your dad doing?"
"Totally fine. Still can't walk, but he says rehab starts in the fall."
"That's great to hear!"
Himari Nee-chan is the president's only daughter—six years older than me. She's always loved kids, kind and nurturing, and now she works as a nursery teacher. She's taken care of me since I was a baby. Once, she even told me, "Changing Chi-kun's diapers was what made me realize I wanted to be a nursery teacher~!"
We used to take baths together until I was in third grade. The last time, she was in ninth grade, and I remember my heart racing at the sight of her budding chest. After that, I got too embarrassed and refused to join her. Looking back, I kinda regret that now.
"Himari Nee-chan, you seem really happy today."
"You can tell~? The day I've been waiting for is finally here~♪"
"What day?"
"That's a seeecret~! Not telling Chi-kun yet♪"
"Chifumi-kun. Before today's insemination, let me brief you on the recipient's specs."
In the lobby of a luxury hotel in Tokyo, Ohno-san started explaining. This is the same place where he yelled last time—how is he so unfazed? This guy's got nerves of steel.
"Listen up—169 cm tall, measurements 88-60-88, D-cup. A supermodel-level beauty. Lucky you."
"That's tall. First time meeting someone taller than me. Is she a model?"
"Ah, you're 165, right? Yeah, she's got some height on you. Just act like you're relying on your big sis, and you'll be fine. Her job's not modeling, though—she's a nursery teacher. Time's almost up, so get going."
"Got it. I'm off."
"Oh, one more thing. Today's recipient is your second one. But don't overthink it—just fulfill your duty. That's what she wants most."
I didn't get what Ohno-san meant—until a few minutes later.
"Ch-Chi-kun?!"
"H-Himari Nee-chan...!"
So that's what he meant by "second." My second recipient is someone I know... What do I do? I'm not mentally prepared for this...
"Chi-kun, why are you here?"
"...Why? Because I'm... I'm the one who's supposed to..."
"No way?! You're a Genius Gene Holder?!"
"...Yeah. Sorry."
"Don't apologize! I'm just shocked. Does your dad know?"
"No. I'm still debating whether to tell him... What should I do?"
"I see... Hey, Chi-kun, it's okay."
Tears are coming out. How pathetic. I'm not ashamed of being a sperm donor, but I never wanted my family to find out. I know they'd judge me, and the thought of Himari Nee-chan hating me made me cry without realizing it.
Ah...
"Chi-kun's still such a crybaby, huh?"
Himari Nee-chan hugged me gently. Her chest was soft and warm.
"What do I do...? I never wanted you to find out like this. You'll hate me..."
"Don't cry. You didn't do anything wrong. I could never hate you."
"But... but with Nee-chan... like this..."
"Y'know, ever since middle school, I've wanted to have a Genius Gene Child. I convinced my parents and finally got approved as a recipient. I've been so excited ever since the insemination date was set."
"Is that why you were in such a good mood the other day?"
"Yep! I was looking forward to it, but honestly, I was a little nervous too. Doing... that... with a stranger felt kinda scary. But when I saw you, I felt relieved somehow. Weird, right?"
I shook my head.
"Not weird at all. All the recipients genuinely want children, and it's my duty to make their wishes come true..."
"I was really surprised, but now I'm glad it's you. I'm sure I'll have a kind child just like you."
"Himari Nee-chan..."
"Hey... let's take a bath together, like we used to."
Unlike regular hotels, this one had a spacious bathroom with a jet bath. Leaning against the tub, my heart raced as the door clicked open.
"It's been so long since we did this."
Himari Nee-chan wasn't wearing a thing. Well, it's a bathroom—of course not. But seeing her naked after so long... she was stunning. Her D-cup breasts were perfectly shaped and full, accentuated by her slim waist. Her round hips balanced everything out, and her tall, slender limbs gave her a model's figure. Her arms were slightly tanned—probably from playing outside with the kids—which was oddly alluring.
"Let me wash you, Chi-kun."
Just like old times, she sat me on a stool. Standing behind me, she poured shampoo over my head.
"You never liked getting your hair washed, did you~? Said it stung your eyes."
"I'm not a kid anymore. I can handle shampoo."
"Uh-huh, you're all grown up now~."
The sound of sudsing filled the air, but I couldn't focus. Every now and then, her nipples brushed against my back. No! If I get hard now, she'll think I'm a pervert! ...Wait, I'm supposed to get hard eventually. Still, her fingers feel amazing. I could let her wash my hair forever.
"Next, your back."
She lathered up with body soap and scrubbed my back, then moved to my arms before coming around to face me. Bits of foam clung to her skin—just like when we were kids.
"You've always used way too much soap, Nee-chan."
"Guilty~. I'd go through body wash so fast, Mom would scold me all the time. But doesn't lots of bubbles just feel nice? Like it makes you happy?"
"Yeah. It does."
The same silly, carefree conversations as before. Feels like time rewound.
"Ah! Chi-kun, you're all grown up down there too!"
"Th-This is...!"
What an unfilial son—just getting washed got me rock-hard. But it's not my fault. It's been five days since my last release.
"Remember when this happened back when I was in ninth grade? You were in third grade, and this thing got all big~."
"I-It's not my fault! It just happens!"
"I know, I know. Boys will be boys. But back then, I didn't understand anything. After that, you stopped bathing with me..."
"Did I...? I don't remember~."
Playing dumb, but I remember it vividly. That was the moment I started seeing Himari Nee-chan as a woman. The guilt made me stop bathing with her.
"But y'know... I'm really happy I get to wash you again."
She'd been meticulously cleaning my dick for a while now. The slippery soap made it more ticklish than pleasurable, but... how long was she planning to keep this up?
"Wow... it's so big... Will I be okay?"
"Himari Nee-chan?"
"Ah, sorry! It's just... I haven't touched a penis since you were in third grade, so it's kinda fascinating."
"Wait... does that mean you're...?"
"Yep. I've never been with a man before. So Chi-kun... you'll be my first♡."
