Doctor's Surprise Visit
After that, they continued stimulating the uterus to induce ovulation, but unfortunately, due to temporary depletion, no egg came out.
The state of Topaz, who had overdone it due to her greed and fainted from the climax, worried the protagonist, so he slipped out of the bed and checked on her.
A soft, wet sound filled the air as the last remnants of the fluids dripped from the protagonist's body.
Everything inside seemed to have been turned into aphrodisiac fluid. The amount that had been spurting like a fountain was now reduced to mere droplets, like light rain.
The bed mattress was soaked with a puddle of it.
'What the hell is this?'
Even though Topaz was rich, buying a new mattress wouldn't hurt her account, but for some reason, the bed soaked with Topaz's fluids had a strange feeling, as if it could be traded for high prices in the underworld.
In the original story, one learns that items used in certain events are traded for high prices in the underworld.
And if one achieves a certain lewdness or reputation, one can sell one's own items. In the early days, this was used to sell underwear and raise initial capital.
Topaz didn't seem safe for that.
'Hmm... shall I try drinking it?'
-Chuuuueup
Just as the protagonist was about to head to the kitchen to give Topaz some water, since there was plenty of biological mineral water here, it would be fine to filter a little from the body and give it to her.
Enjoying the slightly sour and salty taste while absorbing the fluid, the bed had become completely fluffy.
-Chuk♥
-Gulp... gulp♥
Then, creating a mouth-shaped tentacle, the protagonist deeply kissed Topaz and fed her the clean, pure biological mineral water from the body, unlike the water in the plastic bottle full of microplastics.
Thinking this would wake her up, but since she seemed very tired, after tidying the room a bit, the protagonist decided to rest as well.
Having replenished the fluids, the protagonist entered Topaz's depths again to enjoy the nest with peace of mind.
"Hng♥ Hhuueut...♥"
To minimize stimulation, the body was made as thin as possible and entered, but since Topaz's body was already lewdly developed, even this strong stimulation made it seem like it would spurt again. So, creating a mouth on the back part that hadn't entered yet, the last drop was sucked without dirtying the bed that had been made fluffy, and the body could settle back into the uterus.
'Huu... What a day of accomplishments. Good night~!'
Just as the protagonist was about to fall asleep, feeling tired inside, consciousness blurred and fell into deep sleep.
.
.

"Uueum~... Huaaam. Slept well..."
Waking up, to loosen the strangely heavy body, the protagonist stretched.
Clearly, after the battle with the witch, the only thought was to do the tentacle, so the memory was hazy.
Due to the aftereffects of the witch's battle, the body felt much heavier than usual, but the protagonist remembered that coming home, the tentacle made the protagonist feel very good.
Thanks to that, even in the midst of going crazy wanting to do the tentacle, the head was clear without any noise, refreshed.
The result of hard work to fulfill one's secret fetish.
That the child was much smarter and superior than thought was purely luck, but the efforts to gain knowledge to not turn the tentacle into a simple monster after obtaining the egg and to become stronger.
Thanks to this driving force, the protagonist thinks he could reach Jewel-rank.
Although it's something one can't tell anyone, the effort to reach Jewel-rank to safely fulfill the desire to be raped by the monster of one's preference.
Thanks to the child's superiority, the protagonist could peel the virgin skin faster than thought, so now, every time there is time, it will be possible to do with the child, so anticipation builds from now.
Thinking about the indulgent life, due to excitement, the child didn't get pregnant despite being trained by the protagonist, but the milk that flowed out soaked the chest.
Thinking about pregnancy, worry about the child naturally arose.
The tentacle has the ecology of giving birth to dozens or hundreds of eggs by combining only the superior genes from the ova it has consumed until the end of life.
The wish to put the real egg inside and make the child pregnant and the greed to stay with the child long stirred.
While unconsciously stroking the belly while thinking about pregnancy.
"Eh... like this, temporary....?
Eeeeh?!"

Because of the fatigue from the battle, the body wasn't heavy!!
The belly was really swollen as if pregnant.
Because the breasts were large, the lower part was hard to see, so finally went in front of the full-length mirror to check and only then could confirm what kind of state it was.
"T-tentacle...? Ah, no...?"
Cautiously stroking the belly.
Is the superior child having short lifespan? Or because too smart, knowing I want to get pregnant, it burned its own body?
At that time when all the arrogant thoughts were...
-Twitch♥
"Hyaet?!♥"
The movement in the womb was felt.
"A, ah...! It's there..! G-good, it is..."
Thinking calmly, recalling that the tentacle prefers to be inside the uterus, the protagonist felt relieved and gently stroked as if dealing with a real baby in the womb.
"Fufu... how did you know the word for 'mom' and engraved it."
Though speaking casually, honestly, when seeing the engraving for the first time, the stomach dropped.
The memory after the battle with the witch is hazy, but the abnormal strength of sexual desire is remembered, but it was typical symptoms of erosion by black mana.
Now, no black mana felt inside, but if this child absorbed the black mana and became a real monster and engraved the word with the black mana, it would have to consider suicide before falling.
If the Jewel-rank protagonist had become a parasite of the tentacle and continued to grow stronger using it as a nest... even imagining it, the damage would have been terrible.
-Twitch♥Twitch♥
As if reading the protagonist's worry, the child stimulated the uterus in a dissatisfied manner.
"Hut♥ S-slowly...♥ The stimulation is too strong♥"
Although it's questionable where the black mana went, fortunately, the engraved word was not more or less than just drawing a picture with mana.
Although the word is also in the category of black magic, the child engraved it in the uterus considering no black mana, so even if it's magic, it's just a bunch of mana gathered to be visible to the eyes.
Even the intention in the mana could be read, but only sexual desire was felt.
Even though mana was divided to not be exposed to black mana, it made one laugh thinking if pure sexual desire could exist like this single-celled organism reproducing.
Then, the fact that it has intelligence to understand words is probably the reason the child is attractive.
"Fuhuhu... shall we be together for a long time...?♥"
-TwitchTwitchTwitchTwitch~!
Due to the sudden thought when waking up, the happy movement of the child twitching madly at the flowing true feelings made the protagonist climax helplessly.
"O..ooh?! Ooooh!!♥"
Just from shaking the body happily, climaxed helplessly and all strength left the body.
Until yesterday, outside, so even if the child opened eyes to black mana and tried to dominate, could handle somehow, but now, truly settled in the uterus, even in the worst situation, unable to resist, that fact made the protagonist feel very thrilling.
Even now, unable to use even magic, let alone black mana, and the fact of being helplessly jerked off by the child who only knows how to use mana primitively gathered was too sweet.
"Haaat...♥ Haaat...♥ I, really...♥ became the tentacle's bride...♥ Hhuueut...♥"
-TwitchTwitch♥
Unable to hold back the surging excitement, the protagonist brought hand to the crotch and rubbed it.
-Twitch! Twitch!
"Huaaaat!!! O, ooh?! Hooooh?!♥"
Just before, the child was simply twitching the body, so again climaxed from stimulating the uterus with many protrusions and rubbed the crotch as if milking a cow, squirting milk.
"Aaa... aaaah♥ I became a fool...♥ T-tentacle's bride...♥ Don't look at it all day...♥ Rubbing is bad..♥ Hhuue...♥"
Really, the intelligence was lowering, head was hazy, tongue loosened.
I want to rub the crotch all day without doing anything...♥
"The things I do are for the fallen woman... tsk, failed again this time. It worked well on that woman... but the sample is too lacking."
"Het...?"
-Chyuuk♥Chyuuk♥ Chguk
"If you saw a person, stop your hands?"
"Hhuueungueut?!♥"

"A, it shot out... I really hate it..."
"Un... niihi...?"
Long black hair, long enough to use as blanket, bushy.
Like a person wearing white researcher gown, very dark dark circles and black glasses making the dark circles even darker.
Even in this disheveled attire, showing the beauty that can't be hidden... one of the most famous people in B-city in many meanings, Doctor.
The only person who knows the protagonist's secret preference and the biggest help in obtaining the knowledge needed to raise the tentacle, for some reason, dropped by the protagonist's house.
"Eolssi gu, looks like you've become a bellyful so soon, seems you've been stealing from me without saying a word."
"A... no... hhuueut...♥"
"How long has it been?"
"About three days...?"
At the protagonist's words, Doctor showed a startled expression and soon fell into deep thought, not saying anything, habitually stroking chin in worry.
Because of the special ability healing, called Doctor, but by nature a scholar, prefers developing or researching various things, so likes to be called Doctor rather than Professor.
Since the protagonist knew her since the apprenticeship days, when the protagonist became adult and first drank alcohol, in a drunken state, told about the protagonist's wall, and without laughing, rather recalled possibilities like turning monster into livestock, helped in various ways to meet and tame the child currently held.
"It's definitely a special individual... it came from the egg I stole last time, right?"
"Yes, I couldn't see it hatching. When I went, it seemed not long after. It was eating the egg that hatched as you told me."
"The egg wasn't special... rather, selected from the high mana organ generating entities that might not generate mana organs."
"Eh? Really? This kid is really smart. Almost all my words are understood...!"
At the protagonist's words, alternating looking at the swollen belly and the protagonist's face, with hesitant expression, stepped back a bit.
"Not even cat mom, but real tentacle mom is tough..."
"A, really...! Really?! Tentacle... come out a bit... I, I want to see..."
-Twitch..?
"Huuet, i-it's okay... she's my close older sister... the one who helped hatch you."
Honestly, if it wasn't embarrassing to be seen with the swollen belly like pregnant in front of the sister and muttering like a crazy woman, it would be a lie, but the child's action of flinching as if understanding the words made the protagonist happy no matter what.
Just the mind to quickly show this child to the sister and boast grew.
-Chyuurruk
"Oho♥?!"
"Aaaak!!! It shot out again!! Really!! If you want to take it out, send me out and do it!!"
"Huu... hihi...♥"
Due to the post-orgasm fatigue and the rare sight of the sister's excited appearance, the protagonist laughed like a fool.
-Twitch! Salangsalang~
And the sight of the child stretching its body as if greeting and waving a small branch like greeting was very heartwarming.
"Shit... not only can it understand words, but it greets...? Did you train the tentacle? What kind of training did you give it?"
"Eh? I didn't do any training like that...?"
"...Have you shown it greeting?"
"Eh... when I first entered the barrier, I hid in the clothes and greeted the military uncles, but otherwise I hid in the house."
"....."
Hearing those words, the protagonist's expression suddenly hardened.
"Hey, Topaz. Are you eroded? It was so unbelievable I almost let it slide. If Red Uncle is sure, then it's really eroded."
"Eh... that... the memory is hazy, but after coming home yesterday, I gave the stored egg and did crazy things... then fainted and woke up, it was okay."
Although the sister knew the protagonist's wall, but to tell everything about sexual life, shame came.
"From the situation... it seems that guy did something."
The sister muttered while extending a hand to the tentacle.
"Since you absorbed black mana, there should be black mana...
No trace of black mana. This isn't a simple irregular...
Aah~!! My head hurts! This isn't the place. It seems I need a precise examination. So, put it back in the tentacle for now and come with me.
I'll wait in the car."
The sister scratched her head in trouble and, after thinking that there was no answer, finally shouted and headed out of the house first.
"...Hehe♥ I have no choice~ Tentacle, come in♥"
-Chyuurruruk
"Ooh♥"
