It'll Be Much Warmer and Tighter Than a Fake One
Slurp... Sluuurp...
I busily worked my tongue.
I sucked on the glans like a lollipop and licked up the frenulum.
I was doing my absolute best to make up for breaking her pocket pussy.
M-my jaw feels like it's going to dislocate...
Arin's cock was so thick that I couldn't even fit it properly into my mouth.
With tears welling up in the corners of my eyes, I looked up at her.
"Haaah... If you look at me like that..."
Her cock twitched inside my mouth, leaking pre-cum.
It was a relief that she seemed to find even my clumsiness endearing.
Still, this level of stimulation was clearly nowhere near enough to make her cum.
"*Slurp*... *Pah*... *Pant, pant*... I'm sorry, it's just so big..."
As I pulled away to catch my breath, a thick string of saliva stretched between us.
Because a succubus's saliva is naturally viscous, it created an unintentionally lewd sight.
"I-it's okay. If it's too hard, you don't have to force yourself..."
Arin waved her hands dismissively, but I could clearly see the flash of disappointment in her eyes.
At the same time, a shiver of anxiety ran down my spine.
If I let Arin leave like this, Lilith might punish me with strict orgasm control...!
"No! I'll do my best. If you let me use my hands too, I think I can make it feel much better..."
Leah looked up at Arin pleadingly.
Begging to serve her while kneeling right beneath her crotch...
If someone had told me I'd end up like this when I first became a succubus, I never would have believed them.
"Of course it's okay...! Please, do whatever feels comfortable."
"Thank you! *Mmph*—"
I gently took her swollen balls into my mouth.
Feeling the semen bubbling inside them with my tongue, I stroked her shaft with my hand.
Squelch, squelch.
A sticky, wet sound echoed through the trial room.
Even though I couldn't swallow her entire cock, my constant drooling had coated it in a layer of saliva that felt no different from high-viscosity lube.
"Ah... U-um, if you don't mind..."
"Hmm...?"
"May I stroke your hair...?"
I blinked at Arin's sudden request.
I knew she had a timid personality, but I didn't expect her to ask permission for something like this.
I popped her balls out of my mouth for a moment and gave her a soft smile.
"If you don't mind getting covered in semen, of course you can touch me as much as you want."
I rubbed my cheek against the inside of her thigh and took her other testicle back into my mouth.
"Ah... O-of course it's fine, since it's my own cum anyway..."
Trembling slightly, Arin placed her hand on Leah's head.
She stroked her hair incredibly gently, as if touching a cat for the very first time.
Sticky...
The thick semen smeared on Leah's hair clung to Arin's fingers, but she didn't seem to care.
"You're so cute..."
It was as if Arin couldn't even see the mess.
She just gazed lovingly at Leah, who was sucking her balls and stroking her cock.
"I want to take you home and keep you..."
"*Slurp*... I'm sorry, but you can't do that..."
"A-ahahaha... Yeah, I figured."
Having accidentally let her true feelings slip, Arin gave an embarrassed laugh.
After I spent some time stroking her shaft and licking her balls...
"Leah. Are you planning to do that all day? The customer's cum is going to build up faster than you can clean it~"
Leah flinched and froze in place.
Seeing this, Lilith addressed Arin directly.
"Dear customer, this was our employee's mistake, so you don't need to go easy on her. I specifically tied her hair into twintails so you could use them as handles. Just grab them like a pocket pussy and use her throat~"
To think there was such a lewd reason behind it.
I had my suspicions, but hearing her call my hair "handles" out loud made my face burn hot.
Throb, throb.
My uterus had become so accustomed to this that it now mistook harassment for praise.
With trembling eyes, I quietly let go of her balls.
"...Just as my master said, you may use me however you like."
Although the thought of a cock that size entering me was terrifying...
A succubus's body recovers quickly, so it should be fine, right?
To confess my more honest feelings...
I hope she pours it straight into my stomach.
The brief spark of sadism I had felt earlier completely died down.
Instead, my masochism as a beta futanari began to crawl back up.
Though it wasn't visible from this angle, a puddle of Leah's love nectar had already formed on the floor.
On top of that, I hadn't eaten anything since breakfast.
While I didn't need to eat three meals a day like a human, going without food for over twelve hours made my uterus thrum with hunger.
"Are you really sure it's okay? I'm worried I might break you..."
"Ah... If it gets dangerous, my master will step in."
The nuance of being treated like a mere tool made my entire body shiver.
"I've been wondering about something since earlier..."
Gently grabbing my twintails, Arin let out a series of ragged breaths.
"Why is your hair tied up with condoms?"
"Ah... A customer who visited this morning tied it like this—"
Leah cut herself off.
The condoms currently hanging from her hair were filled with Yeon's semen.
Lilith had told her to keep them on because it looked hot, but thinking about it, wasn't it rude?
Wearing condoms filled with another futanari's cum like hair accessories...
"If it makes you uncomfortable, should I take them off?"
"No! It's not uncomfortable, it's just... it's incredibly hot."
As I hurriedly tried to remove the condoms, Arin grabbed my head firmly.
The sudden grip squeezed the condoms, causing the semen inside to slosh around.
"Did all the customers who finished their trials tie those?"
"A-ah, no. Just one person did it."
"Whoa... They must have been an Alpha futanari."
Her voice carried a complex mix of emotions.
It was the typical inferiority complex of a Beta, believing she could never do such a thing even if given the chance.
Yet, at the same time, there was a sting of jealousy, feeling like someone else had beaten her to it.
The grip on my hair tightened.
Even though we had just met today, she was already starting to view Leah as her possession.
Feeling that intense emotion directly against my skin, I spoke up.
"I don't really know what an Alpha futanari is... but to me, you're an Alpha futanari too."
"Huh?"
"So..."
I stuck my tongue out and opened my mouth wide.
"Please shove it into my throat-pussy as much as you want, and fill me up inside..."
It was a plea to be used like a tool, declaring myself lower in the hierarchy.
Overwhelmed by a rush of arousal and emotions she had never felt before, Arin yielded to her desires.
"...Even if it's hard, just bear with it for a bit."
"*Mmph*... *Gug*... *Cough*..."
She forced her cock into my small mouth.
Because she shoved it in so forcefully, my teeth scraped against it slightly, but instead of causing pain to her sturdy futanari shaft, it only seemed to provide a new kind of stimulation.
"*Gag*... *Gurgle*..."
Just from having the cock shoved all the way in, Leah was gagging and tapping out on Arin's thigh.
Normally, the timid Arin would have panicked and pulled out, but...
"Haa... Haa... I feel like I'm going to cum soon, so just a little. Let me enjoy this just a little longer."
A Beta futanari was still a futanari.
Moreover, because she possessed a massive shaft perfectly suited for an Alpha, the sadism that had never had a chance to manifest until now exploded outward.
As she gripped the condom-tied twintails tightly and thrust her hips, a symphony of wet sounds filled the room.
Squelch, squelch.
My soft, tender throat clamped down tightly every time her cock plowed through it.
"Haa... Ah... Nngh...!"
Unable to contain her excitement, Arin groaned as she vigorously pumped Leah's throat-pussy like a pocket toy.
"*Gurgle*... *Gag*..."
Leah's face turned pale from the lack of oxygen, yet it was completely flushed with pleasure.
Trickle...
The fear that I might actually die, combined with the extreme pleasure, made me involuntarily leak urine onto the floor.
Regardless, Arin didn't stop her relentless thrusting.
"Nngh... I'm cumming!"
She didn't hold back the rapidly rising urge to ejaculate and let herself go.
Her testicles visibly convulsed up and down.
Spurt! Gush! Splurt!
A waterfall of semen shot directly into Leah's stomach.
Leah no longer had the strength to even tap out.
"*Gulp*... *Mmph*... *Hic*..."
There was nothing I could do but swallow the endless torrent of semen pouring into me.
After barely managing to take the massive ejaculation with a hazy mind, I felt her erection soften slightly.
N-now, I can finally breathe...
Before I could even finish the thought, and while waiting for her cock to slide out...
"Ah... I'm sorry. Cumming so much made me need to pee..."
"*Gurgle*?!"
Before I could stop her, a different liquid rushed in right after the semen.
Comparing the semen to a waterfall earlier was a mistake.
This was like a hose being pinched shut and then suddenly released, unleashing a violent torrent of water.
Leah couldn't resist and filled her stomach with Arin's urine as well.
All of this happened in a span of less than five minutes.
When Arin finally pulled her cock out...
"*Cough, wheeze*... *Cough, cough*..."
As oxygen rushed back into my lungs, I coughed reflexively.
"A-are you okay?! I'm so sorry...!"
Belatedly realizing what she had done, Arin patted my back, but Leah still struggled to breathe properly, coughing continuously.
"*Burp*... *Cough*... *Hic*... I'm, I'm sorry..."
To make matters worse, a semen-scented burp escaped my lips in the middle of it.
After coughing and burping alternately for a good while...
"*Pant*... *Pant*... Did it feel good...?"
I finally regained my senses and let out a silly giggle.
The extreme pleasure I had just experienced for the first time paralyzed my brain, completely overshadowing the fear of almost dying.
"*Ugh*... U-um, I'm sorry. Your cum and pee mixed together like a cocktail inside my stomach..."
My shy excuse, accompanied by me stroking my slightly bloated belly, was more than enough to make Arin's cock—which had finally calmed down—spring back to life.
"Oh...? It got big again."
"It's because you keep being so hot, Leah."
"Hehe... I'm sorry."
Having completely lost her rational mind to the irrumatio, Leah forced strength into her legs and stood up.
Even though she had swallowed a massive amount of semen, a succubus driven purely by instinct could not be satisfied with just this level of energy absorption.
"Since it's my fault, please let me take responsibility with my pussy."
"Huh...?"
The service, which was supposed to end with the throat-pussy trial, had escalated into an invitation for sex.
From this point on, it had absolutely nothing to do with testing adult toys.
Since the intercom remained silent, it was as good as Lilith's tacit approval.
Leah turned around, spread her pussy wide with her own hands, and wiggled her hips.

"It'll be much warmer and tighter than a fake one... okay?"
A succubus covered in semen, with condoms tied in her hair, dangling her own cock while begging to be filled—it was a temptation that kept her erect even after ejaculating three times.
"This... this is your fault, Leah...!"
"Ahhn?!"
Her mind completely blank, Arin shoved her 20-centimeter cock inside without hesitation.
