Chapter 68: To the Fountain of Pure Love
I had a feeling it would come to this someday.
Not that I predicted every detail.
But to say I never imagined it would turn out like this would be a lie.
Chalking it up to youthful indulgence—devouring physical pleasure, drowning in sex—is easy.
But what happens when emotions beyond lust pull two people together?
What lies ahead is… unknowable, shrouded in mist.
“—Ngu!♥♥♥ Nmu!♥♥♥ Chubu!♥♥♥ Chu!♥♥♥ Nn!♥♥♥ Ngu!♥♥♥”
Yuu, facing away with her hips toward me, crawled over me on all fours.
She eagerly sucked my penis.
And…
“—Nchu… chumu… rero… chu… haa, chu…”
Beneath her, I closely observed her vulva, teasing her slit.
Having pulled down each other’s underwear, exposing our genitals, we were in a sixty-nine position, ravenously savoring each other’s sex.
In her house—the Onodera family’s hallway.
“—Nn!♥♥♥ N-No, not there!♥♥♥ My c-clit…♥♥♥ If Ren-chan touches it…♥♥♥ If Ren-chan marks it with his memory…♥♥♥ If it’s developed…♥♥♥ I’ll pass out every time I masturbate!♥♥♥ I won’t be able to masturbate anymore!♥♥♥”
“…Just a little. Let me tease it a bit more.”
“Nmoo~!♥♥♥ Ren-chan, you’re such a perv!♥♥♥ From now on, when I can’t hold back with masturbation, I’ll have Ren-chan’s penis creampie me!♥♥♥”
“Yeah… do whatever you want…”
“—Nfu!♥♥♥ Haa—mu!♥♥♥ Oishii!♥♥♥ Ren-hyan ooinhin!♥♥♥ Oishii!♥♥♥”
She kept sucking my penis.
I kept teasing her vagina.
“…Oh.”
After caressing her secret spot for a while…
A slow drip… the amount of fluid leaking from her vaginal opening had surged.
Massaging her labia majora and minora, occasionally brushing her clitoris, I indulged in her hypersensitive genitals.
Gently kneading her clit with my thumb—kuni-kuni—or sometimes spreading her labia minora wider—guni-guni.
Her budding pubic hair, soaked in her own love juices, clung to her skin.
The vaginal flesh peeking beyond her labia glistened pink, reflecting the hallway’s light.
Her urethra, the slight bulge below, and her vaginal opening twitched lewdly—hiku-hiku.
…Erotic.
Hopelessly erotic.
It made my crotch even harder.
And it wasn’t just her down there that was erotic.
Looking elsewhere, at other parts visible from here…
Her white skirt, flipped up at her waist, and black panties dangling on one leg.
Half-undressed, she shuddered—biku-biku—each time she lightly climaxed, her long black hair swaying, her back arching, her hips wriggling seductively.
Yet she didn’t stop caressing or being caressed, tucking hair behind her ear and resuming her noisy—chubu-chubu—sucking of my penis.
Her state amplified the visual eros of this act’s depravity, its decadence, to the extreme.
Here we were, in the hallway where she lives her daily life, indulging in this.
As if a wave of decadence was eroding the everyday, sweeping away our thoughts.
“Crazy…♥♥♥ This might get addictive…♥♥♥”
“Really?”
Yuu seemed to love this play. She was clearly into sixty-nine.
…Or maybe it’s the thrill of doing this in the wrong place—her hallway—that’s got her hooked.
“Getting to do whatever I want with Ren-chan’s penis…♥♥♥ And Ren-chan developing my pussy…♥♥♥ It feels like I’ve completely become Ren-chan’s…♥♥♥ Like Ren-chan’s made me his, and it’s the best…♥♥♥ Maybe!♥♥♥ —Nn!♥♥♥ Nuuuu!♥♥♥”
“Uwoh…!?”
Mid-lewd monologue, she climaxed again, her body trembling—biku-biku—her back arching sharply.
Her snow-white abdomen, like a pristine ski slope, caved and relaxed repeatedly, her muscle spasms visibly intense.
Deep within her labia minora, which I held open, her tiny vaginal opening tightened—kyuu—clenching shut.
“—Nhyan!?♥♥♥”
I tried slipping my fingertip into that narrow opening, but…
It was clamped so tightly—kyu-kyu—it wouldn’t budge.
Earlier, I could just barely fit one finger; now, nothing.
Like pursed lips refusing a pretzel.
Incredible…!
To think I’ve been thrusting my penis into such a tight hole.
A birth canal meant for a baby someday… it seems almost impossible.
The mystery of the human body.
“Ren-chan, you’re so focused on there…♥♥♥ Do you like my pussy?♥♥♥”
“Y-Yeah…”
With a melted, gleeful smile, she peeked upside-down from between her legs, looking back at me.
She talks about her genitals like an object, offering herself up, but I’d never treat her body that way. She knows I wouldn’t.
“Ren-chan, you’re such a perv…♥♥♥ So, how’s it going?♥♥♥ Ready to creampie me yet?♥♥♥”
“Y-Yeah, I really want to… but let’s keep going like this a bit longer.”
“…Nfu!♥♥♥ Sounds good!♥♥♥”
She turned her upside-down face back and resumed sucking my penis.
Slowly, deliberately.
But steadily, we heightened each other’s arousal, building sexual pleasure.
“…”
I focused on teasing Yuu’s vagina.
Gently kneading her clit—kuni-kuni—massaging her labia—guni-guni—sometimes sucking her vaginal flesh. Tracing her contours with fingers and tongue, confirming her shape.
I relished her texture and her joyful, pleasured reactions above all.
She played with my penis—licking, sucking, oddly smearing her saliva on it (?).
Sometimes curious about my scrotum, she’d graze its underside or cup it in her palm.
Gazing at my penis up close, she’d giggle lovingly, tracing it with her fingers.
“Sniff-sniff♥♥♥ Sunsun♥♥♥”
…Occasionally sniffing it, as if remembering to,
“—Haamu!♥♥♥”
She’d stuff the head into her mouth, tongue teasing the tip in her full mouth.
…Like kids trying a new toy, satisfying sexual curiosity, we explored each other’s bodies in our own ways.
This was a new kind of intimacy for us.
It felt like learning sex techniques tailored to each other’s bodies.
“—Nbu…!♥♥♥ …Nfu!♥♥♥”
Yuu, for some reason, pulled her mouth off my saliva-soaked head, giggling—kusu.
She rubbed my glistening penis, smearing her saliva—nuchu-nuchu.
“What’s up?”
“It’s just…♥♥♥”
She shook her shoulders, amused.
“Updating these naughty memories with Ren-chan is so fun…♥♥♥”
“I see.”
Funny—she was thinking something similar to me.
“And it feels like our feelings, our desires, are perfectly aligned…♥♥♥ My womb is aching, it’s crazy…♥♥♥”
“W-Well, I see…?”
She wriggled her hips gleefully, her emotions a bit more intense than mine.
“…”
Feeling shy, and a bit mischievous…
Her shapely, average-sized butt.
I grabbed both cheeks firmly—munzu—
“—Nnu!?♥♥♥”
Like I’d done with her slit, I spread her buttocks with my thumbs—kupa.
Her slightly darker anus peeked out.
“Yaa…♥♥♥ Suddenly…♥♥♥ Ren-chan, what’s up?♥♥♥”
“…”
Come to think of it, I hadn’t touched here yet.
Stimulated by my relentless caressing of her vulva, her anus twitched—contracting with muscle spasms.
I stared blankly at the tightly puckered, quivering hole.
“—Ha!?”
Yuu snapped back, curving her body and craning her neck to look at me.
Panicked expression.
“Wait, that’s off-limits!”
She raised her voice, stopping me.
As expected, her sensitivity and intuition were sharp.
“If Ren-chan insists… I’ll prepare…♥♥♥”
“…!”
What! She’s open to it?
“No… sorry, I was just teasing.”
“Nmoo…♥♥♥ Ren-chan, warn me about that stuff first!♥♥♥”
“My bad, my bad.”
Apparently, prior approval is needed.
Her front gate is always open, but the back gate requires a pre-issued pass.
Like an employee-only entrance.
Or a no-trespassing zone…
…What am I even thinking?
My thoughts are all over the place.
“But… if we did it, how would it work…? Lube to start, right? In those naughty videos Ren-chan watched, that’s how they did it…”
“Why do you know that?”
How does she know my porn history? I pushed the thought aside.
I don’t want to dwell on my masturbation habits as a healthy guy (me) dealing with natural urges.
That’s private, sacred.
A guy enjoying porn needs solitude—freedom, salvation.
Alone, quiet, rich…
What am I rambling about?
Focus, we’re in the middle of this.
“—Ah!♥♥♥ Your penis twitched just now… are you actually into butts…?♥♥♥”
“Hmm… I’m not not interested, but thinking about it…”
Her anus, still twitching from my vaginal caresses’ aftershocks.
Darker than the surrounding skin, wrinkled, tightly closed.
Undeniably an asshole.
But as a narrow hole barring even air, it’s oddly equivalent to her vaginal opening. Women’s holes captivate men endlessly.
Honestly, saying I’m totally uninterested would be a lie.
…But, though not as much as Yuu, I have a primal yearning for the act of creation itself.
My body and mind find greater pleasure in penetrating her womb-bound vagina than her anus.
…Saying this out loud would sound dehumanizing, so I’d never voice it.
“If you really want, I’ll take all of you…♥♥♥”
Yuu, with a melted smile, looked back, provocatively shaking her hips—furi-furi.
“I’m Ren-chan’s wife…♥♥♥ I want to get pregnant with Ren-chan’s semen…♥♥♥ I’d prefer all your semen in my vagina…♥♥♥ In my womb…♥♥♥ Spurting everywhere…♥♥♥”
“…I see.”
Her pregnancy obsession is as strong as ever.
I swear I won’t let her get pregnant while we’re students.
“Plus…♥♥♥ You promised to creampie me all week…♥♥♥ For a while longer…♥♥♥ Keep intending to impregnate me…♥♥♥ Shoot your semen in my vagina…♥♥♥”
“Yeah.”
Right, she made me promise creampies all week.
She slipped that in casually… I’ve been too careless.
Her lust—no, her love—knows no bounds, growing unchecked.
With her instincts merging with reason, I can’t predict how serious she is or if she’ll spiral toward pregnancy.
“…Nfu!♥♥♥ Ren-chan, I loooove you!♥♥♥ Amu!♥♥♥”
“—Kuh!!”
Having climaxed repeatedly, she trembled finely but kept caressing my penis as if devoted.
…I’m nearing my first ejaculation.
“Gonna cum! I’m cumming, Yuu!!”
“Un!♥♥♥ Let it out!♥♥♥ Go!♥♥♥ I’ll drink it!♥♥♥ Ren-hyan!♥♥♥ Your semen!♥♥♥ Shoot it in my mouth!♥♥♥”
My penis swelled, the head bloating in her mouth as she opened her throat, ready to swallow.
“Kuh…! I’m—cumming!!”
“Nn!?♥♥♥ Nuuuuuu!♥♥♥”
Byururu—byururu—byuru—byuru.
Flashes of light flickered in my vision as intense pleasure surged through my hips.
A fleeting sense of emptiness.
My hips weakened slightly.
Yuu, still on all fours with her hips toward me, her jaw visible between her legs.
“Nn!♥♥♥ Nbu!♥♥♥ Nn!♥♥♥ Nku!♥♥♥ —Nku!♥♥♥ Nku!♥♥♥ Nku!♥♥♥”
Her throat—kokyu-kokyu—gulped, struggling to swallow my copious semen.
Sucking tightly, lips pursed to spill nothing, her effort was obscene.
I couldn’t see her face.
Just her jaw, her lower lip, clinging to my penis like a snapping turtle.
So erotic.
“—Nn!♥♥♥ —Nbu…♥♥♥”
“Uh!”
Chupon—she released my penis with a sound. Unfazed by its post-ejaculation sensitivity, she licked off her saliva.
…Still hiding her face.
Yuu lifted her head.
“…Kuchu… nfu!♥♥♥ Kuchu, kuchu… nfu~!♥♥♥ Kuchu-kuchu…♥♥♥”
Giggling gleefully, making lewd, vulgar sounds in her mouth.
“Nku!♥♥♥ N~… kuchu-kuchu… kuchu!♥♥♥ —Nku!♥♥♥”
Swallowing the last of my semen, she sat up.
Turning to me…
“…Haa!♥♥♥”
Yuu exhaled hot breaths from her mouth, revealing the pink flesh of her inner cheeks and her pristine white teeth, ensuring not a drop of semen remained.
And then…
“Thank you for the meal, Ren-chan!♪♥♥♥♥ I think I can finally drink all of Ren-chan’s semen!♥♥♥♥”
“…!?”
Her sweet, melted whisper sent a shiver down my spine, making my heart skip.
“…Ren-chaaan!♥♥♥♥”
…It’s like a switch flipped in Yuu.
She impatiently stripped off her white skirt, tossing it aside—poi.
Straddling me now, facing the same direction.
Her drenched crotch, her fully aroused body, rubbed against mine.
“…Ren-chan♥♥♥♥”
A lascivious, decadent, endlessly bewitching smile played on her lips.
“Ren-chan!♥♥♥♥ It’s still so…♥♥♥♥ So big even after cumming once, amazing…♥♥♥♥”
“…”
Our genitals remained exposed.
Her honey-soaked vagina brushed against my penis.
She confirmed the unyielding rigidity of my erection with her vagina.
Despite my slight shock at her overwhelming lust, I had no intention of refusing her.
“My darling!♥♥♥♥ Ren-chan♥♥♥♥ Ren-chan♥♥♥♥ Ren-chan♥♥♥♥”
“…”
I slowly nodded, meeting the glint of madness in the deep abyss of her black eyes.
“Yuu. I love you.”
“~~~~~!?!?!?♥♥♥♥ I-I love you too!♥♥♥♥ I love you so much!♥♥♥♥ I love you more than the universe!♥♥♥♥ I love you, Ren-chan!♥♥♥♥”
…Her anxiety, her instability despite showing such intense feelings—maybe it’s partly my fault, my behavior.
What should I do moving forward? How can I fully accept her feelings? Pondering this, I caught her body as she slowly lowered herself onto me.
“I’ll give you everything!♥♥♥♥ All of me!♥♥♥♥ So creampie me!♥♥♥♥ Get me pregnant!♥♥♥♥ Make me your wife!♥♥♥♥”
“No pregnancy…”
…As always, she subtly shifts the purpose of sex from an expression of love or bonding to pregnancy.
I can’t let my guard down…
“Well, no rush. I’ll make sure to get you pregnant eventually.”
The calm part of me tilted its head—huh? That line, taken at face value, sounds like something a total scumbag would say. I’ll get you pregnant—why would a guy say something so arrogant?
“~~~~!?!?!?♥♥♥♥ R-Ren-chan…♥♥♥♥ Yes!♥♥♥♥ Get me pregnant!♥♥♥♥ Impregnate me!♥♥♥♥ Let me bear your child!♥♥♥♥”
…As expected, she’s thrilled. Overjoyed, she grinds her vagina against the underside of my penis.
It’s a clumsy attempt at sumata—more like a failed insertion than a deliberate act.
“…Uh.”
Oh… the tip of my penis grazed not just her slick vaginal flesh but also her sprouting pubic hair—shori—creating a unique pleasure.
“—Nuu!♥♥♥♥ I’ll definitely get pregnant!♥♥♥♥ Let’s put it in!♥♥♥♥ Let’s make a baby!♥♥♥♥ I’m getting pregnant now!♥♥♥♥”
“No pregnancy.”
…Gently chiding her.
Yet, despite my sexual arousal, I felt an odd calm. I wanted to thrust into her vagina, pound her depths—a fierce urge. But I also wanted to tease her, heighten our feelings before she lost herself completely, indulging in such saccharine thoughts.
…Needless to say, my crotch was raring to go.
Swollen to bursting, rock-hard.
Her complete immersion in sex and relentless pregnancy talk showed my erection’s unwavering maleness.
But my barely-held rationality reminded me.
All this—it’s thanks to Yuu.
“…Hey.”
“Ren-chan♥♥♥♥ Ren-chan♥♥♥♥ Ren-chan…♥♥♥♥”
“Yuu, listen.”
I had to say it. Gratitude needs to be expressed.
…No.
I wanted to say it.
Not just thanks for making my dick hard.
…Everything Yuu’s done for me.
My current state—it’s all because of the strength she’s given me.
In my less-than-ideal family situation, she knew and supported me.
I want my deep feelings for her to reach her somehow.
“Thank you, Yuu. I’m able to be this energetic—all because of you.”
“~~~~~!?!?!?♥♥♥♥ W-Why!♥♥♥♥”
“?”
Expressing my daily gratitude, Yuu trembled—biku-biku—her mouth twisting as if angry, her emotions lightly chaotic, almost comical.
What does she think of her current state? Her face, trying to suppress a grin unlike her usual sloppy smile.
…Even if she grinned outright, I wouldn’t be put off at this point.
“—W-Why say that!♥♥♥♥ Why say things that make me so happy so casually!♥♥♥♥ It’s driving me crazy!♥♥♥♥ I can’t take it!♥♥♥♥ I’ll definitely get pregnant!♥♥♥♥ I’m absolutely bearing your child!♥♥♥♥”
“No pregnancy, I said.”
She throws out supreme expressions of love without hesitation.
Always aiming for pregnancy, waiting for the moment I slip and permit it.
Breathing heavily, voice high, lightly panicking—her words probably aren’t serious…
But I’m scared I’m getting used to her “pregnancy” talk.
If I truly got used to this…
I’m terrified she’d get pregnant out of nowhere.
…No, with Yuu, she would do it.
The moment I say “okay,” she’d be like, “Yay♪” and weeks later, casually confirm she’s pregnant.
“Why not!♥♥♥♥ Bearing your child is my greatest joy!♥♥♥♥ Impregnate me!♥♥♥♥ Get me pregnant!♥♥♥♥ Right now!♥♥♥♥”
“No pregnancy…”
…Here we go again, the usual back-and-forth.
The same “I’ll get pregnant” vs. “no pregnancy” argument.
I’ve explained why pregnancy’s off-limits countless times. Her memory’s not reset—she’s just overwhelmed with emotion, and I won’t rehash the reasons.
She knows, and she’s unraveling.
It’s kind of amusing, and I feel my expression soften.
My mood lifts.
Yuu, whose very existence is a reward, deepens my love for her.
“…”
“Ah—♥♥♥♥”
Seeing my expression, Yuu’s eyes widened slightly, unable to hold back, flashing a massive niyaaa grin right at me.
She looks so happy…
“You smiled!♥♥♥♥ That’s rare!!♥♥♥♥”
“Huh…?”
I smile all the time, don’t I…?
“No, I mean!♥♥♥♥ You smiled from the heart!♥♥♥♥”
“I always smile from the heart…”
How rude.
I know my face is usually deadpan, but I do smile when I’m happy…
“No, no!♥♥♥♥ I know!♥♥♥♥ Ren-chan’s real smile!♥♥♥♥ Yes!♥♥♥♥ For me!♥♥♥♥ Only for me!♥♥♥♥ Oh, Ren-chan!♥♥♥♥”
Something struck a chord, and she started chanting my name like a broken record.
“Ren-chan♥♥♥♥ Ren-chan♥♥♥♥ Ren-chan♥♥♥♥ Ren-chan♥♥♥♥”
…Yup, her switch is fully on.
“Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥Ren-chan♥♥♥♥—”
The slick—nyuchi-nyuchi—grinding of her vaginal flesh felt amazing.
Her honey drenched my penis, enhancing the sticky, pleasurable contact.
“Ren-chan!♥♥♥♥ I’m putting it in!♥♥♥♥ I’m gonna insert it!♥♥♥♥ Your penis!♥♥♥♥ Your cock!♥♥♥♥ In my vagina!♥♥♥♥ In my pussy!♥♥♥♥”
“Yeah—”
Yuu lifted her hips.
Confirming my penis was upright, she grabbed it, aligning the tip with her vaginal opening.
Pausing briefly, breathing heavily—haa-haa—she roared with fervor.
“I’ll definitely get pregnant!♥♥♥♥”
“No pregnancy, okay?”
No openings, no mercy, I thought, watching her lower her hips.
“Here we go—pregnancy sex!♥♥♥♥”
“I’m not letting you get pregnant.”
Trying to make me accept pregnancy at every chance—she’s relentless, I thought.
