Succubus Is Just the Absolute Best...
The wet tongue pushed its way into her anus.
Even when she reflexively clenched, it did nothing to stop the intrusion. Instead, the slick saliva made everything slippery, allowing it to slide even deeper.
“Chuuup… Unlike humans, succubi don’t have bowel movements. We don’t eat food in the first place.”
“Th-then…?”
“We eat semen and excrete semen.”
Squish, squish.
The hand stroking her shaft while licking her ass.
“Ah, if you touch me there right now… hngh…!”
Without any resistance, thin semen dribbled out of her urethra. All she could do was tremble helplessly from the pleasure coming at her from both front and back.
“That’s why it’s healthy for a succubus to ejaculate every single day.”
Replacing meals with semen.
Substituting bowel movements with ejaculation.
Normally, she wouldn’t have understood a word of that explanation.
‘The structure is completely different…!’
But experiencing it firsthand made her realize it instantly. For a succubus, the anus wasn’t an excretory organ at all. It was a pleasure hole designed to allow her to absorb even more essence at once…!
“Chyup… slurp… Your anus is such a cute pink too. Lia really doesn’t have a single unsexy spot, does she?”
“Mngh…”
At Liris’s teasing, her womb throbbed reflexively. Being called sexy was apparently the highest compliment a succubus could receive.
“So soft and springy, with such great tightness. I should make an onahole modeled after our Lia’s ass later.”
“Hngyiii…!”
Her tongue swirled around, tracing every inch of her inner walls. The clear intent to map out every single detail was unmistakable. Her sphincter clenched and unclenched wildly on its own.
“Chuuuup… Pwah. This should be enough prep.”
“H-huu…?”
Prep for what?
Her anus twitched open and closed after the tongue withdrew, and she glanced back.
“Oh, you don’t know about this either? Succubus saliva is usually used as high-viscosity gel. Hmm, should I explain what high-viscosity gel is first?”
“…I know what that is.”
She had made it all the way to the final interview at an adult toy company. Of course she knew.
Not all gels—or rather, lubricants—were the same. They were broadly divided into three categories by viscosity:
High-viscosity.
Medium-viscosity.
Low-viscosity.
The higher the viscosity, the thicker it coated and the milder the stimulation. Conversely, the lower the viscosity, the thinner it spread and the stronger the stimulation became.
“You can use saliva as gel…?”
“It’s not just usable—it’s preferred. Succubus saliva is naturally very sticky.”
She never imagined succubus spit could substitute for high-viscosity gel.
“I poured plenty inside you earlier, so you won’t get hurt.”
Squelch—
Liris rubbed her glans against Lia’s anus. Thanks to the saliva she had applied herself, a sticky, wet sound echoed through the room.
“Do you need to measure anal depth too…?”
Lia’s anus twitched nervously. She already knew the size of the cock that had knocked on her womb earlier. If something that big entered her ass, which existed purely for pleasure…
Drip.
A mix of anticipation and fear caused the last drops of semen left in her urethra to leak out.
“Hm? No, the anus doesn’t have a cervix like the womb, so it just keeps going in. No need to measure.”
“Then why are you…?”
“You haven’t eaten anything yet, right? I have to feed you.”
As if in response, her womb pulsed with a needy throb. It felt similar to a stomach growling—except what it craved wasn’t food, but semen.
“A succubus can ingest semen through her mouth, womb, or anus. Of course, taking it straight into the womb is the most efficient.”
Squuuuish—
The glans forced open her clenched anus and slowly pushed inside.
“Hghk…!”
“I’ll fuck your ass while checking how sensitive it is.”
Once the head was in, the rest slid in smoothly. Her inner walls squeezed tight as if urging it deeper, greedily swallowing the shaft.
With just a slight downward push of Liris’s hips—
“Ooooooh…!”
“Hoo… It went all the way to the base so easily?”
The cock was sucked in without resistance. Unlike her pussy, whose folds clung to every inch, her anus concentrated its powerful grip solely at the entrance.
“Mmm, the inside really is hot and fluffy. It feels amazing.”
“Heghuuu….”
Every stir of Liris’s hips pressed firmly against her inner walls.
Splurt, spluuurt….
Her pussy, as if jealous of the ass that was feeling good all by itself—or perhaps trying to show it could do better—leaked dissatisfied streams of nectar.
“I’ll move slowly, okay?”
“Hah… haaah…”
“Looks like you can’t even answer anymore?”
Liris chuckled and leaned forward, pressing their bodies together. She grabbed Lia’s breasts and began rocking her hips, gently bumping their pelvises together.
Squelch, squelch—
Even though a succubus’s rear was a hole made for insertion, it didn’t produce natural lubricant. Despite the generous amount of saliva Liris had poured in, the friction was far stronger than in her pussy, gripping the cock so tightly it could barely pull back out.
“Huu… My familiar has such a perfectly sex-optimized body. You’re too adorable.”
Chuu, chuu.
Liris kissed the back of Lia’s neck while gently rolling her hips.
“Oghk… hnguuuh…”
The brutal, thick rod buried in her ass. The gentle lips caressing her neck. The contradictory pleasures hitting her at the same time short-circuited her brain. Drool had been spilling from the corner of her mouth for a while now. Since she was a succubus too, it stretched in long, sticky strands instead of breaking.
“Want me to go a little deeper? This should be your S-shaped colon…”
“Hyaaagh!”
The glans stubbornly pushed into a place it absolutely shouldn’t. The forced straightening of her curves made pleasure explode like fireworks.
“And pressing here reaches your womb.”
Squeeze.
This time she pulled back slightly and pressed down on the lower part. The precise hip movements targeted her womb through the intestinal wall.
“Ughk…!”
An animalistic sound burst out of her involuntarily. Her womb screamed in delight as well, squirting violently.
Shoooooooosh…!
The powerful squirt was blocked by Liris and flowed down over her swollen balls and thighs.
“Ahaha, did it feel that good?”
“Huu… hng… Pressing on my womb… is dangerous…”
“So our Lia likes having her womb pressed more than her S-shaped colon?”
“N-nooo…”
Even her sloppy refusal sounded like nothing but seduction with her melted tongue. A sadistic smile rose on Liris’s lips. She moved the hand that had been fondling Lia’s breasts down to her waist.
“Then I’ll make you feel really, really good, okay?”
“I really don’t— ohooooh…?!”
She started slamming hard against Lia’s ass with powerful thrusts.
“Hup, hoo… I’ll cum a lot, so make sure you eat every drop, alright?”
“Ugh, ngh… hek… haaahng…”
Pow! Paaang! Paaang—!
Her soft ass rippled with every impact. Her sphincter kneaded the base of the cock as if begging for cum.
Liris didn’t disappoint. The moment the urge to ejaculate peaked, she slammed her hips flush against Lia’s rear.
“It’s coming…!”
Brrrrrrrrrr! Brrrrrrrrrrrrrrr….
It was like someone had cranked a faucet all the way open. The sheer volume made it hard to believe this was only one ejaculation.
“Nnghuuuh…!”
Lia’s toes stretched out straight. Her sphincter clamped down like it refused to waste even a single drop, milking the cock for everything it had. The way her balls twitched and forced out even more semen that should have been impossible was just a bonus.
Glurk, gluuuurk….
Liris’s thick, sticky semen poured endlessly into her rectum. Even visually, her lower belly was visibly swelling.
During her very first anal feeding as a succubus, Lia thought with a hazy mind:
‘So this is how succubi eat…’
Any sense of reluctance had already been crushed beneath countless pistoning thrusts. Right now, she was completely drunk on the warm, sweet semen filling her belly.
‘Succubus is just the absolute best…’
Being able to satisfy both sexual desire and hunger at the same time. Her former male ego faded further as she even entertained the dangerous thought that it might be fine to have sex every single day.
Several minutes later.
“Lia? No matter how hard you squeeze, nothing else is coming out.”
“Heuuu…?”
The long ejaculation had finally ended, but Lia’s sphincter kept rhythmically clenching the base as if it didn’t understand that.
“I’ll pull out now, okay?”
“Hooogh…”
When the half-softened cock was withdrawn—
Glurp….
The semen she hadn’t yet absorbed leaked out.
“Aww, I told you not to let it spill.”
“S-sorry…”
Lia moved her sluggish hand to cover her leaking anus. It was an instinctive reaction born from not wanting to waste precious food.
“It’s fine. It’s your first feeding, so it’s okay to be clumsy.”
Liris got up from the bed and walked over to the drawer. She took something out of the same drawer where she had pulled out the Ruler Condom earlier, then returned to stand in front of Lia’s ass.
“Can you move your hand for a second?”
“Y-yes…?”
Still dazed, she moved her hand aside.
Squuuish.
“Hiiiik…!”
Cold metal pushed into her entrance. She whipped her head around in surprise.
Liris let out an affectionate laugh.
“I put in an anal plug. This way, the semen won’t leak, so you can absorb it slowly.”
“Ah…”
The foreign sensation in her ass felt incredibly strange, but it certainly seemed like it would prevent any more precious semen from escaping.
“Up we go.”
Liris lifted Lia and laid her down in a proper position, then lay down beside her and pulled her into a tight embrace.
“The body measurements are really done now. You worked hard on your first day.”
Chuu.
The moist kiss against her cheek. Feeling the warm skin pressed against her entire body slowly brought her mind back to clarity.
“Auuu… Just what did I…”
In just a few hours, she had been turned into a futanari succubus, lost her virginity, and even had her ass opened. If she had told yesterday’s self about this, she would have been scolded for not even making the lie believable.
It was that unrealistic, that close to a nightmare.
“Now that your belly’s full, you must be getting sleepy, right? Let’s sleep well and wake up refreshed. The store opens tomorrow.”
Why did Liris’s hand stroking her semen-filled belly feel so gentle? Why did the voice whispering in her ear sound so sweet?
Exhaustion weighed down her eyelids. She slowly drifted off.
“Good night, my lovely familiar.”
Listening to her Master’s enchanting voice until the very end, and growing accustomed to the strange feeling of the plug in her ass, Lia fell fast asleep.
