Now You Know What It's For?
“Come on, raise your arms for me.”
“Huh? Wait, just a sec—”
Before Lia could protest, Liris stripped the T-shirt right off her.
Her breasts bounced free.
Cold air kissed her bare chest, and her pale underarms were suddenly on full display.
“Hmm. Pretty pink nipples. Not a single hair anywhere, either.”
“W-Wasn’t this supposed to be for measurements?”
“Shape and feel matter more than numbers. Now spread your legs a little?”
Lia obediently parted her thighs, a flicker of confusion crossing her mind.
Why am I being so compliant? I’m getting naked in front of someone I just met…
She felt embarrassed—her cheeks burned crimson—but the urge to disobey Liris never surfaced.
“Heh. Wondering why you’re so obedient?”
“How did you…?”
“It’s written all over your face.”
Liris chuckled and tugged Lia’s pants down, giving her butt a playful pat. Lia’s hips lifted on their own, making it easy, and the garment slid to the floor without resistance.
“It’s because you’re my familiar. Succubi’s familiars have a hard time going against their master’s words.”
Her finger traced the womb tattoo just below Lia’s navel.
“Hnng…!”
A strange pulse rippled through her lower belly. Even though the organ hadn’t existed until moments ago, she understood exactly what it was.
My womb… is reacting…?
The newly formed uterus seemed to rejoice at Liris’s touch, as if it were praise.
“If you gathered enough essence you might resist, but you’re still a virgin. You have no choice but to obey me.”
“That’s so unfair…”
“Unfair? Where else are you going to find a master as nice as me? Most succubi would shove their cock in the second they made a familiar.”
A shiver ran down Lia’s spine. If something that big entered her…
Now that she could sense her womb’s location, the thought made her skin crawl. Yet even that reaction felt like obedience to her master.
“H-Huh…?”
“Oh my. Your pussy’s getting wet all on its own to make it easier to take.”
Without any conscious decision, her vagina had soaked through her panties, as if preparing itself so the massive shaft wouldn’t hurt her.
“That’s not— This is just…”
“A physiological response, right? I know.”
Liris stroked her hair like she understood everything, then yanked the panties down in one motion.
“Oh my… You’ve got something cute down here.”
Lia’s penis—slightly larger than when she had been male—along with her brand-new vagina, were now completely exposed. Clear fluid trickled from both her pussy and the tip of her cock.
“C-Cute…?”
“Even the way you get embarrassed is adorable.”
Liris leaned in and pressed a soft kiss to Lia’s forehead, then pulled her upright. Only then did the height difference become obvious.
“Shall we measure your height and weight first?”
“We didn’t need to take my clothes off for that…!”
Lia frantically tried to cover herself—one arm over her breasts, the other shielding her lower half—but it was hopeless.
“Mmm? Are you trying to seduce me right now?”
“N-No…?”
Her full breasts and dual genitals spilled around her small hands, only making the view more lewd.
“I’d love to taste you, but… we have work to do.”
Liris licked her lips, tail flicking, her violet eyes gleaming dangerously—yet she restrained herself and pointed to the scale in the corner.
“Step on and stand straight for me?”
“Hnng…”
Lia climbed onto the scale, fidgeting. The womb tattoo glowed faintly as her arms were forced down to her sides.
The measuring rod hummed upward, brushing the top of her head.
“Mm-hm. Big breasts, wide hips, pretty pink nipples and glans. You’re perfect for working at our store.”
Liris circled her slowly, openly admiring the naked body.
“You really don’t have to say that out loud…”
It was mortifying enough to be examined naked; having each part commented on was worse. But the most embarrassing part was—
“That was a compliment. Aren’t you happy? Your inner thighs are getting even slicker than before.”
“My brain just hasn’t synced up with my body yet…!”
Her honest pussy kept leaking under Liris’s gaze.
“We’ll figure out who’s honest soon enough.”
Liris smiled and checked the results.
“Height 157.8 cm, weight 52 kg. You’re surprisingly slim for someone with such huge tits.”
She cupped and gently fondled Lia’s breasts as if she couldn’t believe it.
“Hnn… Calling them ‘tits’…”
A moan slipped out. Heat flooded her body and her thighs rubbed together involuntarily.
“Want me to check exactly how big they are?”
Liris’s touch grew bolder, squeezing and stroking until the soft flesh trembled.
“Ahh…!”
When her fingers brushed the areola, Lia couldn’t stop the needy sounds.
“F-cup, maybe?”
“You can tell just by touching…?”
“Of course. What kind of master do you take me for?”
Her hand slid downward, caressing the tattooed belly before moving to Lia’s back.
“Hnn… Hah…”
“Your body’s very sensitive. You’re an ideal employee for our store.”
Liris stepped closer and grabbed Lia’s butt firmly.
“Hii…?!”
A little squirt of fluid escaped.
“Your ass is so soft. I could knead it forever.”
“Haaah…”
“Three sizes: 92-56-90.”
“How can you tell with just your hands…?”
“Because I’m your master, obviously.”
Liris flashed a seductive smile and brought her hand around to the front again.
“Shall we check down here too?”
“W-Wait, that place is sensitive—”
“I know. I’ll be gentle.”
“Hnnk…!”
Her fingers wrapped softly around Lia’s penis, forming a ring with thumb and forefinger to stroke the shaft. It twitched and began to swell without resistance.
“Flaccid length about 5 cm, girth 8.5 cm.”
Liris finished measuring the soft state in no time.
“And you produce quite a lot of precum even before getting hard.”
“D-Don’t say that…”
The slick fluid coated Liris’s hand.
“Let’s see how big it gets when fully erect.”
“Hnng, hah…!”
She began pumping in earnest. Lewd wet sounds filled the air as Lia’s cock stiffened rapidly. Liris rubbed the glans with her thumb.
“…Ah, so this is as big as it gets?”
She laughed softly upon realizing it had already reached full hardness.
“Looks like you have more talent on the female-receptive side.”
“Huu…? Female-receptive…?”
Lia’s mind was melting; she couldn’t quite follow. Whether it was Liris’s skillful touch, her heightened sensitivity, or both—she couldn’t tell.
“Just like people are left- or right-handed, futanari are divided into those better with their cock and those better with their pussy.”
“Hnn…?”
Even if she’d been clear-headed she wouldn’t have understood; now sweet pleasure fogged her thoughts and all she could do was moan dumbly.
“And aptitude usually follows size.”
The stroking sped up. Lia’s hips tensed.
“M-Master, I’m… about to…”
“Mm, I’ll make you come right away. Anyway, having talent on the female side means this.”
Liris opened a drawer with her tail and produced a beaker, placing it in front of Lia’s cock. Then she licked Lia’s ear and whispered.
“A cock that’s only 10 cm long and 11 cm thick even when fully hard can’t possibly have male-receptive talent.”
“Hnnk…!”
“You’re close, right? It’s okay to let go. Come hard right into this.”
“Haaah…!”
With that gentle yet merciless verdict, orgasm crashed over her. She could feel the semen surging up her urethra with shocking clarity. Her balls twitched and pulsed.
Thick, creamy cum—far richer than when she had been male—shot into the beaker.
“Good girl. Let’s get the rest out too.”
Liris squeezed and milked every last drop from the shaft.
“Hmm… 135 ml? Considering it’s your first ejaculation, we should consider the average lower than this.”
“Uuu…”
Lia’s legs gave out; she slumped against Liris. Even though she’d come plenty of times as a man, the pleasure was on another level.
Liris caught the trembling girl and held her gently.
“Combined ball weight around 160 g. Alright, penis measurement complete!”
She gave the balls one last playful squeeze before finishing.
Lia rested her head against Liris’s chest, still twitching.
What just happened…?
In moments her cock had been thoroughly measured and she’d been declared to have no male-receptive talent.
It only grew about 2 cm…
The relief she’d felt earlier now seemed pathetic. Before she could even hope to get dressed again, Liris began removing her own necktie.
“H-Huh? Why are you taking your clothes off, Lady Liris?”
“You were calling me Master so nicely earlier. Now you’re using my name again?”
“I just spaced out for a second— That’s not the point! Why are you undressing?!”
Seeing her own female body was embarrassing enough, but seeing someone else’s naked form was far worse.
Liris ignored her and stripped in seconds, then pressed her breasts firmly against Lia’s.
“Hnng…!”
Their nipples rubbed together, stiffening. Soft mounds squished and flattened against each other. Even that contact sent waves of pleasure through her—then Liris pressed harder.
“Hiiik?!”
A hot, firm pressure pushed against her lower belly.
“You asked why I’m undressing? There’s still one place we haven’t measured yet.”
Liris smiled, rubbing the head of her cock against Lia’s abdomen.
“Your pussy. Length, elasticity, tightness, weak spots… If you have no talent on the male side, you must have it on the female side. Let’s test just how exceptional you are.”
“Th-That’s…”
Lia’s brain went white. While she stood there speechless, Liris’s tail opened another drawer and retrieved a small box.
“These are condoms with measurement markings.”
She took out a vitamin-like packet, tore it open with her teeth, and revealed a condom printed with numbers on the outside. She rolled it down her fully erect shaft all the way to the base.
“…Hah.”
“Hehe. Now you know what it’s for?”
The belated realization made Lia clap a hand over her mouth. If they were going to measure her vagina with a marked condom…
“We’ll know your depth by seeing how far my cock goes in, right?”
She intended to measure by actually penetrating her. The number visible on the condom once it reached the root read—
“18 cm…”
“A little bigger than you, isn’t it? Don’t worry, I’ll be gentle.”
It was a size that would have been called massive even in her original world. Imagining that huge shaft forcing its way inside her made her pussy clench and gush fresh fluid.
