"Should I just go ahead and put it in?"
Ayaka-san straddled my lap and removed her bathrobe. Her completely naked form was unbelievably beautiful. Her translucent pale skin, slender limbs, tightly cinched waist, and perfectly round breasts of just the right size - the pink nipples standing pertly at their peaks. Though her lower area had a light covering of hair, it modestly guarded her private parts.
Of course, if Ayaka-san's face was God's masterpiece, then she must have been given a body to match. The woman exposing everything before me now had no flaws from the crown of her head to the tips of her toes.
Ah, I want to become one with her right now. But... is this really okay?
"...Wait, Ayaka-san."
"Huh?"
"You said hello to my penis, but I haven't greeted yours yet!!"
I embraced Ayaka-san and laid her down on the bed.
"Ah, wait..."
I spread her legs and brought my face close to her crotch.
"No, Chifumi-kun, that's embarrassing!"
"It's fine! Let me see!"
"Geez! Pervert! Lecher! You dummy!"
"But Ayaka-san, you licked mine earlier! It's only fair!"
"Th...that may be true but...ah, don't stare so much, it's embarrassing..."
Ayaka-san's slit was slightly moist, and the scent emanating from it stimulated the deepest parts of my brain.
"Ayaka-san, here I go!"
"Okay...do what you want♡"
Ayaka-san covered her face with both hands.
"Let's eat!!"
Splat, splat, splat, splat.
I rolled my tongue over her clitoris and sucked at her vaginal opening as if coating it with saliva.
Lick lick lick lick lick.
Ayaka-san trembled violently. She seemed to be enjoying it, which made me happy.
Slurp slurp slurp.
"Hyaaan! Ah, ah, ah, ah, ah, ah, ah, ah, ah, Chifumi-kun, no, not there, I'll go crazy~"
Ayaka-san was too cute - I couldn't hold back. My lower half had been rock hard for a while now, and I wanted to do something about it...that's it!
"Ayaka-san, please take care of mine too."
Saying this, I positioned myself over her in reverse and resumed cunnilingus. Now my dick dangled right before Ayaka-san's face. Would she meet my expectations? Ah, she did!
Gulp, suck, lick, slurp, splat.
Ayaka-san actively moved her tongue.
Splat, splotch, lick lick lick.
Not to be outdone, I licked all around her pussy.
Lick lick lick lick lick. Slluuurp!!
"Hauu, fugu, mugu, uun, chu-pa"
While sucking me off, Ayaka-san seemed to be desperately suppressing her voice. So cute.
Lick lick lick lick lick.
Lick lick lick lick lick lick.
"Ah! Auu, nn, nn, nn, nn, nn, nn, nn, Chifumi-kun, no, I'm, I'm going to cum...ahhhhhhhh!!"
Splaaaaash!!
The moment Ayaka-san reached climax, love juice gushed from deep inside her.
"Whoa!?"
Startled by the sudden event, I couldn't help but shout. Ayaka-san looked embarrassed.
"Sorry...when I feel too good, it comes out."
"It's fine! I'm happy you felt so good! So, can I put it in now?"
She blushed and silently looked down. Still on all fours, I repositioned myself to face Ayaka-san.
"Amazing...it's already soaking wet..."
I rubbed my swollen glans up and down against Ayaka-san's slit. Her pussy, drenched in love juice, was unbelievably slippery - if I didn't hold it, my dick might slip right out.
"Okay then, here I go."
"...Mmm, okay."
Sluuuurp. Squish squish squish, sploosh!
"...Ngh, it hurts"
Ayaka-san grimaced. Looking closely, tears were spilling from her eyes.
"D-did it hurt!? I'll pull out!"
"Wait!"
Ayaka-san frantically stopped me.
"Don't pull out. Please. Stay like this a little longer."
"But you look like you're in pain."
"No. It's just...it's been so long since I had sex that my body isn't used to it yet. I'll adjust soon."
I see...if you haven't had sex in a long time, it can be like that.
"How long has it been? When was the last time?"
"Second year of college, so about four years ago?"
"That long! Didn't you have any boyfriends?"
"Of course not. I applied to be a Genius Gene Recipient around then. If I carelessly had sex with someone and got pregnant by accident, everything would be ruined."
"Ah...right...of course."
To become a Genius Gene Recipient, you must meet several conditions. One is being nulliparous - meaning anyone who's given birth even once immediately loses eligibility. This is why many applicants are virgins. However, exceptions are made for children who are Genius Gene Children themselves - those wanting multiple children are prioritized for reapplication. This is what Yua-san meant when she said she wanted two or more children.
I don't know why these conditions exist, but it's easy to imagine how a child would feel knowing their mother intentionally had genius half-siblings with different fathers.
"...I think I'm okay now, try moving slowly."
"Okay!"
As Ayaka-san caught her breath, I began moving my hips little by little.
"Ah, ah, ah, ah, ah, ah, ah"
Ayaka-san's initially pained expression gradually relaxed.
"Ngh"
Her vaginal folds clung to me, and the incredible pleasure made me moan involuntarily.
"How is it? Does it feel good inside me?"
"Yes. It's amazing."
"Good. I'm starting to feel good too."
"Then I'll move more."
Squelch, squish, glop, slurp.
"Ngh, ah, ah, ah, ah, ah, ah, ah, ah, ah"
Ayaka-san's moans grew louder. Her insides were warm and soft yet tightly gripping me. If I let my guard down, I'd cum immediately.
"Chifumi-kun, let's kiss♡"
"Okay!"
"Smooch, lick, suck, mmm~"
Our lips met. We entwined tongues and exchanged ample saliva. Her mouth tasted incredibly sweet and delicious.
As I kneaded Ayaka-san's breasts and thrust vigorously, her moans grew even higher pitched.
Slap, slap, slap, splat, splotch, splurt, slap, slap, slap, splat, splotch, splurt.
Smooch, lick, slurp, splat, lick, suck, squish squish, schlick.
The lewd sounds of flesh meeting flesh and tongues mixing obscenely echoed through the room.
"Pwah!!"
Not yet - I haven't fully savored Ayaka-san's body yet!
This time I grabbed her left breast with my right hand while taking her right nipple into my mouth.
"Fah!?"
Perhaps startled by the sudden stimulation, Ayaka-san's body jerked.
"Ahh, nooo. Not...my breasts...I can't...ahh...♡"
Her cheeks flushed as she gazed at me with hazy eyes...or so I thought. These moans confirmed it.
"Chifumi-kun, I...I'm going to..."
"Are you...going to cum? I'm...at my limit too..."
I stopped fondling her breasts and poured all my energy into thrusting.
Slap, slap, slap, splat, splotch, splurt, sploosh, paaah!!
"I'm cumming...I'm cumming!...I'm...cuuuuumiiiiing!!!!"
"I'm...cumming tooooooo!!!!"
Splurt splurt squirt squirt gush gush gush!!!
We reached climax simultaneously. I reveled in the pleasure of semen surging through my urethra while Ayaka-san convulsed, savoring the ecstasy with her entire body. I never imagined we could have such perfect sex. Maybe our bodies are just incredibly compatible.
