Lia is a Female Genius?
“Then, shall I put it in?”
“W-Wait, wait, wait! Just a moment, please!”
The glans pressed against her entrance with a wet squelch.
Lia barely regained her senses and grabbed Liris’s forearm.
“Hm? What’s wrong?”
Liris tilted her head, never stopping the slow grind of her tip against the slick opening.
“It’s not ‘what’s wrong’… Hnn… There’s no way something like that can fit inside me.”
“But your lower mouth is drooling and begging me to shove it in right now?”
Liris pulled her hips back slightly, revealing her shaft now thoroughly coated in Lia’s fluids.
Everything glistening on it was Lia’s own love juices.
“Th-That’s only because I’m your familiar!”
“Is that so~?”
Liris smiled softly and rubbed her cock against the entrance again.
“Hnnng…!”
The sensation of the thick head threatening to pry her open made hot breaths spill from Lia’s lips.
“D-Do we really have to measure it like this? No, why are we even measuring something like that in the first place?”
“What do you mean by ‘like this’ or ‘that way’? I don’t get it.”
Liris chuckled and gave her cock a teasing twitch. Lia’s balls lifted slightly as the glans pushed halfway in before retreating.
It was a silent threat: speak properly or I’ll thrust it all the way in.
“Hah… I-I mean, do you really need to insert your cock to measure it…? Why measure the depth of my vagina at all…?”
Her face burned crimson as the words tumbled out.
She had assumed any penetration would happen after serving customers, not like this. The thought of that burning pillar suddenly spearing into her made her heart pound with fear.
“It’s to draw a clear limit line, of course.”
“A limit line…?”
“If a customer shows up with something much bigger than our Lia’s depth, we need to warn them in advance, don’t we? ‘Sorry, that won’t fit, so your experience will be limited~’”
The absurd rejection line left Lia’s mind blank.
“Besides, wouldn’t it be better to have your hymen taken by an expert succubus? If a customer does it for the first time, it’ll definitely hurt.”
She spoke of piercing the hymen as casually as getting one’s ears pierced.
Yet Lia couldn’t deny the logic. If an unskilled but oversized customer took her first time, it would only result in a traumatic experience.
“C-Can something that big really go in without hurting?”
Even knowing her partner was a succubus didn’t bring complete peace of mind.
Eighteen centimeters. Eighteen whole centimeters.
Now that she had a vagina of her own, she was certain.
‘There’s no way that’s going inside…’
Her entrance was so tight a finger would struggle, and her depth couldn’t possibly reach eighteen centimeters.
“Of course it can. Don’t you trust your Master?”
“Hnn…!”
Somehow, Liris’s words made it sound possible. Whether because she was now a familiar or because of those lewd hands stroking her hips, Lia couldn’t tell.
“If you’re this wet already, it’ll slide right in without any pain… But you’re so scared, so I guess there’s no helping it.”
Liris wrapped an arm around Lia’s waist and pulled her close. Their already-touching breasts pressed together firmly, stealing Lia’s breath.
“I’ll kiss you until your head goes all fuzzy.”
“…Yes?”
Before the bewildered question could finish—
“Chuuub… Mmmph…!”
“Chuuup… Chuurururup—!”
A thick, tentacle-like tongue invaded Lia’s mouth. The sudden kiss caught her mid-sentence, leaving her unable to close her lips.
The slick tongue coiled and tangled inside her. Oxygen grew scarce, and her mind began to float.
Under the succubus’s merciless tongue technique, all Lia could do was—
“Breathe through your nose. When we kiss, exhale through your nose.”
“Hah… Hahh… Hehh…!”
“Mmm, maybe that’s still too hard for a beginner?”
While being patted, Lia panted desperately.
“Chuururup… Chuuup—”
“Mmph… Chup…”
She could only swallow the overflowing saliva to keep from drowning.
It wasn’t that Lia was being overly dramatic because of inexperience.
‘Why is it so sticky…?’
Succubus saliva must have been different. Its viscosity was so high that if she didn’t swallow immediately, she truly couldn’t breathe.
“Pwah… Do you think you’ve relaxed enough now?”
After more than thirty minutes of that violent kiss—
“Hehh… Heuuu…”
“Oh my, did I go too far? Your eyes are all glazed over.”
Lia’s mind had half-shut down. Drool trailed from her lips as she surrendered her body completely to Liris.
Yet her succubus instincts remained active.
Chup, chuuup.
Her pussy fluttered and tried to swallow Liris’s glans.
“Fufu… As expected, Lia really does have more talent as a female.”
Since her mind would return to normal the moment the cock was inside anyway—
“I’ll push it in as far as it can go, okay?”
Puuuush.
Liris thrust her hips upward, burying her shaft in one smooth motion. The flooded entrance offered no resistance.
“Nngoooooh…!”
Lia threw her head back and let out a beastly cry. There had been a slight catching sensation midway—her hymen had been opened—but thanks to the abundant natural lubricant, there was no pain at all.
“How is it? Doesn’t hurt at all, right?”
“Haaah… Th-This is…”
“Hm? This is what?”
“D-Dangerous…”
“Dangerous? What is?”
“I-It feels too good… It’s dangerous…”
“Oh my.”
The honest words had slipped out without passing through any filter, her brain already dominated by pleasure. A deep smile spread across Liris’s lips.
“Our Lia really is a female genius, isn’t she?”
“Genius…?”
“Yes, a genius. A prodigy.”
“Hehe…”
Lia, who hadn’t registered the prefix, smiled foolishly.
“You’re gushing so much love juice to make it easier to take, opening wide and begging it to come in, and once it’s inside you’re clenching tight like you’re saying ‘don’t pull out~’ Aren’t you?”
The tightness was something even Liris had never experienced before. It wasn’t merely strong pressure—the clinging vaginal walls seemed to act cute, pleading for her to stay, while the welcoming womb kissed and sucked as if begging for semen.
She wanted nothing more than to fill it to the brim right now, but unfortunately they were still in the middle of measuring.
“Thirteen centimeters… That’s how far it reaches the womb for now.”
“Huuuh…?”
Lia’s unfocused eyes widened. Though she couldn’t speak properly, the meaning was clear: ‘There’s still five centimeters left?!’
“But the vagina has excellent elasticity, you know? Succubi even more so.”
Liris pulled her hips back. The vaginal walls clung desperately, as if refusing to let go.
Chuuuub…
With effort, she withdrew her cock.
“Ooooooh…!”
The glans scraping along the walls made Lia’s eyes roll upward. A waterfall of fluids—pre-cum and love juices—poured out and soaked the floor.
Liris lifted the trembling Lia and carried her to the bed.
“Want to try lying on your stomach?”
“Like… this?”
“Lift your hips up. Yes, just like that.”
Lia followed Liris’s instructions without understanding why, raising her hips.
“The depth changes depending on the position, after all.”
Liris gripped Lia’s waist firmly and pressed her glans back against the entrance. The parted flesh welcomed her as if it had missed her terribly.
“Huu… Especially in doggy style, it goes especially deep. I’ll push it all the way in like this, okay?”
“Hueh?”
Before Lia, who was panting with her tongue out, could even respond—
Paang!
Liris slammed her hips down.
Do you know what happens when a person is hit with pleasure far beyond their limits?
“——!”
Lia demonstrated it firsthand.
Her vocal cords couldn’t even form a scream. Her mind, unable to process the overwhelming pleasure rushing in, shut down completely.
Her body, suddenly betrayed by its own brain, trembled violently as it was forced into an endless climax.
Spurt… Spuuurt…
Thick semen flowed from the tip of her cock like urine—it was only natural.
“Haa… Hah… As expected, Lia really is a genius. You swallowed the whole thing in one go.”
Even Liris couldn’t hide her excitement. The moment she thrust all the way in, the vagina stretched and the womb was compressed. The tightness was like a milking machine, relentlessly squeezing from glans to shaft.
“At this rate, there won’t be any customers you can’t handle, fufu.”
She was the best, both as a familiar and as an employee.
Liris began moving her hips slowly. Part of it was consideration for Lia’s first time, but—
“Kuh… What do I do? Lia’s pussy feels even tighter than the hardest onahole…”
Her naturally gifted vagina clung to every weak point a male would love.
“I’ll have to teach Lia how to loosen her pussy instead of how to tighten it.”
Left with no choice, she continued the gentle pistoning.
Chub, chuuub—
Along with the lewd wet sounds—
Spurt, spuuurt…
Lia’s cock spilled semen with every thrust.
Still holding her hips up, Lia sobbed.
“M-Master… Something’s wrong… My cock is broken…”
It was a miracle she could even speak, however slurred. On top of experiencing female pleasure for the first time, she was enduring endless ejaculation. She had barely managed to cling to a shred of consciousness out of fear that she might truly fly away.
“Broken? This is normal.”
“Nngh… Hah…!”
Paang! Paang!
Liris answered while gradually increasing her speed.
“A futanari’s prostate is located above the vagina. In other words, it overlaps with the G-spot. Does that make sense?”
“Hah… Hnn… Ngh…!”
She had no choice but to understand. The greatest pleasure was crashing into her, clearly revealing the source that forcibly extracted semen.
“When both weak points are attacked at once, of course it feels good, right?”
“Ugh… Hah… Ngh…!”
Thrust, thrust, thrust, thrust!
The glans stroked the tight vaginal walls, forcing orgasm after orgasm. Receiving this much pleasure in her first experience might break her, but—
‘I can’t hold back either.’
Drunk on the masterpiece she had created herself, Liris never stopped moving her hips.
And finally, when the urge to climax rose—
Spurt, spuuuurt— Spuuuurt—!
A thick load, different in sound from Lia’s own ejaculation, poured out. The orgasm lasted over a minute.
Chuuop— Chuuuop—
Lia’s womb clung with all its might, but the condom wall blocked it, leaving only futile sucking motions.
“Huu… Good work, Lia.”
Once her orgasm subsided, Liris pulled her cock out in one smooth motion.
“Haaang!”
Spurt…!
The final scrape against the walls made both love juices and semen gush out at once.
Liris removed the now-heavy condom, tied it off, then licked the semen clinging to Lia’s urethra clean.
“You’re the greatest treasure I’ve ever found.”
“Hnn… Th-That place is sensitive…”
“But I still want to clean you up properly.”
After finishing with a final chuuop, Liris wiped her mouth and stood up. Lia, completely drained of strength, remained on all fours with her hips raised, panting heavily.
“I-Is the measurement over now…?”
She had thought the hell of pleasure that felt like it would bleach her brain was finally over, but—
“Hm? What are you talking about? There’s still one place we haven’t checked yet.”
“What…?”
Liris gently stroked Lia’s hips, then pressed her thumb firmly against the anus.
“Hyah…?!”
“We still have the anal to do, don’t we?”
“Th-That place is dirty…”
“You really don’t know anything about succubi, do you?”
Liris laughed as if finding it adorable and brought her face close to Lia’s rear. Lia instinctively realized what was about to happen and tried to escape, but her trembling only made it look like an invitation.
“Succubi don’t do things like defecation. The anus exists solely as an organ to receive pleasure and semen.”
She couldn’t bring herself to ask why such a thing even existed.
“That’s why it’s clean enough for this.”
Chuuub—
Because a long tongue had just slid into her anus.
“Hyaaaaah…!”
Lia let out a scream-like moan and realized something.
The pleasure of a futanari was terrifyingly high, and this hell of ecstasy would never end as long as she worked here.
