That Look, It’s So Arousing
Let’s organize the situation for a moment.
The familiar I summoned from the Hall of Summoning was a demon, and that demon was none other than Belial, the older sister figure I’d been close with for a long time.
But as it turns out, she is actually a demon who governs lust.
That is why she possesses both female and male genitalia.
The tattoo on my lower abdomen right now is a mark signaling that I have contracted with her.
Aside from my Soul Mark, this other pattern represents the contract.
If that’s the case, couldn’t I just break the contract?
If I break the contract, the familiar is supposed to return to where it came from.
“If you’re thinking about breaking the contract, you’d be better off giving up.”
“How did you…”
“It’s written all over your face, Runi.”
“Even if you’re a powerful demon, the dismissal of a familiar due to a broken contract…”
“You think you wouldn’t be able to handle it? If you’re that confident, go ahead and try.”
She provoked me with an incredibly relaxed tone.
It didn’t feel like a bluff meant to hide her disadvantage from me.
It seemed to be filled with absolute confidence based on solid grounds.
“If I can’t dismiss the summoning, you’ll have to pay a heavy price.”
“Price? What kind of price?”
“To dismiss the summoning, you’d have to break the contract first, right? Then that lewd mark would disappear.”
“Yeah, a mark like this should disappear right now…”
“If you fail to dismiss me, what do you think I’ll do first?”
She began to lick her lips, then pulled that hideous phallus out from her skirt once again and shook it.
Immediately after, her demonic tail wrapped around it and began to rub it back and forth.
Little by little, ever so slowly.
As her phallus hardened, it rose perfectly straight, twitching while leaking pre-cum.
“…Why are you suddenly getting all worked up!”
“I told you. That mark prevents you from getting pregnant, Runi.”
“Y-yeah… so what?”
“If I can’t be dismissed, don’t you think I’ll just fuck you like a dog?”
Without this mark to prevent pregnancy, if that much semen were to enter my womb—
“Hiiiiiik!”
There’s no probability involved; it would be an absolute pregnancy.
“If you don’t want to see your ‘baby room’ working overtime, I suggest you don’t do it.”
Not only being fucked by a demon, but also bearing a demon’s child—I wouldn’t want that even if a blade were held to my throat.
I simply cannot gamble while carrying such an enormous risk factor.
“Tsk…”
“So, I look forward to working with you, Runi.”
“Then why was a demon summoned in the first place? And a demon who governs lust, at that!”
“You know as well as I do that the familiar one contracts with is determined by the summoner’s magical power.”
“Yeah.”
“Then that must mean your magical power is just that extraordinary, Runi.”
Should I take that as a compliment or an insult?
It’s truly ambiguous.
I didn’t desperately hone the talent I’d had since childhood just to contract with a familiar like this.
“Haa…”
Deeply sighing at the desperate situation, I slumped down onto the floor.
“Runi, think positively.”
“What on earth am I supposed to think positively about!”
“Thanks to me, you’ve learned what it feels like to be a female. Plus, you’ve become my exclusive fuck-hole. Isn’t that great?”
“W-will you shut your mouth?!”
“You’ve become a body that can receive plenty of cum without having to worry about pregnancy. You could call this ‘responsible pleasure’.”
She kept chattering away as if she were having the time of her life.
The vulgar words kept reaching my ears against my will, and the resulting headache only added to my torment.
“And your breasts have grown, haven’t they?”
-Poke!
“Heung-yaat♡”
Having approached me at some point, she lightly poked my breasts, which had grown overnight.
Because she poked exactly where my nipples were, a moan escaped my lips suddenly.
“A cute moan. Haa, I want to fuck you like a dog again.”
-Swish! Rub, rub!
After letting out a lascivious breath, she began to rub her erect phallus with her own hand.
As she stepped closer, a shadow of immense length fell over my face.
“Runi, what did I tell you to do when I show you my cock?”
With those words, my lower abdomen, where the mark was etched, throbbed.
A faint vibration hummed, and my chaotic mind slowly began to clear.
No, it would be more accurate to say it started to go blank.
“C-cock…♡”
“Yes, the cock you love so much.”
“Must… suck the cock…”
“Heh, suck it deliciously.”
Her hand no longer rubbed the phallus.
Because my two hands had started rubbing it instead.
“It’s so hot…♡”
I felt a very hot body temperature, fitting for a thickness that couldn’t be gripped by one hand alone.
Every time it twitched, the movement of the arteries was clearly transmitted to me.
“Jju-up♡ Jjo-oop♡ Churu-uuup!”
“Ugh… shall we try putting it all the way into your throat-pussy today?”
“Churu-up… Uung…”
With my mind gone blank from the increasingly thick scent of semen, I opened my mouth wide.
Not satisfied with that, I even used both hands to pull at the corners of my mouth to widen it further.
“Uni… ok-geum-eong o-i-e hyeo-ba-ga-jyo♡ (Runi, shove it into my throat-pussy♡)”
“Yes, I’ll shove it into your sticky throat-pussy.”
-Thrust!
“Eub-eu-eub♡”
The moment her two hands cupped the back of my head, the phallus surged into my mouth all at once.
I wanted to accept this massive cock all the way to the end this time, but even as I tried to open my throat as wide as possible, half was the limit.
“Heu-geu-eub♡”
“Ugh… Runi, try opening your throat a little more. You’re clenching so hard I can’t move.”
“Eub-eu-eu… Jjo-oo-oop♡”
I couldn’t do anything more than this.
I could only clench hard with my lips to taste the phallus that had entered so deeply.
“Haa… Heu-geung! That you’re such a ‘masterpiece’ even here just means you’re a natural-born fuck-hole.”
“Jju-uu-uup♡ Churu-ru-uuup…!”
“Hoo… Heu-eub!”
“O-go-oo-op♡”
She pulled the phallus out for a moment, then thrust it back into my throat up to the halfway point in one go.
It should have been a painful situation where I couldn’t breathe properly, but my pussy was slowly getting wet, beginning to soak my panties.
-Thrust! Thruuuust!
“Eun-go-oo-oop♡ Jjo-oop…♡ Eub-eu-eub!”
“Haa… Heu-eut… I’ll give you a belly-full of sticky morning cum, our Runi.”
She grabbed my head firmly, as if treating me like an object, and moved it back and forth.
The thought that I wasn’t being treated like a human slowly bloomed in my mind.
I was so incredibly aroused that the pleasure of feeling like I might spray my own juices right then and there hit me hard.
“Keu-heu-eub♡ Eu-geu-eub♡”
“Eu-eu-euk♡”
-Splurt!
While thrusting as deep as she could, an enormous amount of semen filled my mouth, and beyond that, naturally flowed down my throat.
“Eu-geub… Eub-eu-eu♡ Gulp…!”
Because I had to focus on swallowing the endlessly surging semen, my Adam’s apple kept moving.
“Eu-eut… Haa…”
Just before her phallus pulled out with a satisfied groan.
“Jjo-oo-oop♡”
I sucked on the glans and even licked the urethral opening, making every last drop of the remaining semen my own.
“Heh, and no one even taught you. You really are a female through and through.”
-Knock, knock, knock!
“Runi, Belial. Is something wrong? I thought I heard strange noises coming from the room?”
Along with the knocking sound, my mother’s voice reached us.
In the blink of an eye, she returned to her human form and walked over to open the door.
Because I had too much semen in my mouth, I covered my mouth with one hand, unable to swallow it all.
“Mother, Runi was very sad, so I was comforting her.”
“Oh, I see. Runi, don’t be too sad. You must have failed yesterday because your condition wasn’t good.”
“Eub-eu-eub…♡”
“It seems she hasn’t been able to compose her emotions yet. I’ll comfort her a little more.”
“Yes, Belial. I’m glad you’re here.”
That was the end of my mother’s sudden visit.
When I heard the sound of the door closing.
“Gulp…!”
I managed to swallow the remaining semen somehow.
“Ha-eu… the taste is so strange…”
“Now you’re swallowing it on your own.”
“What…?”
“When I return to my human state, the effect of the mark is lifted.”
Does that mean I swallowed the semen on my own without the effect of the mark?
“If you want to eat more cum, just say the word. I’ll give you as much as you want, enough to fill your belly until it’s as round as if you were pregnant.”
-Swish!
Whispering quietly into my ear, Belial lightly traced the tip of my chin with her finger.
“Eu-eu-euk…”
“Your parents think you failed the summoning due to poor condition.”
“So that’s why Mother said that.”
“But what to do? You succeeded.”
Having returned to her human form, she circled around me.
She lowered her posture with her hands on my shoulders, and then.
“Churu-uuup♡”
“Hi-gi-iiit!”
She licked my ear canal very slowly.
“I definitely can’t use my fuck-hole freely in Runi’s room.”
“Wh-who is your… f-fuck… fuck-hole!”
“Why? You admitted it yourself.”
“Th-that was because of the mark!”
“Then what about when you swallowed all of my semen when the mark’s effect wasn’t active?”
I was rendered speechless by that irrefutable remark.
If the effect of the mark really disappeared the moment she became human, just as she said, then what were the things I felt?
My pussy kept tingling, and love juices flowed out endlessly.
The tips of my breasts, my nipples, were also tingling.
My lower abdomen, where the mark was etched, throbbed as if it were craving something, sending signals to me.
“That look, it’s so arousing. Think about it even more deeply.”
Anger flared up at her wicked smile.
The moment I jumped up from my seat to at least grab her by the collar.
-Squish!
“Hu-hya-aaang♥”
Her finger went deep into my pussy, along with my panties, and then came back out.
-Splurt!
Immediately after, at a moment I didn’t even realize, love juices erupted from my pussy.
“Th-this is strange-ee-et♥”
I ended up slumping down, pressing my skirt down to somehow hide the waterfall of love juices that wouldn’t stop.
My body had become so strange overnight.
