The Bet (4)
With a strong sensation of flesh being pushed, Charlotte felt once again that she was connected to Isaac.
‘......I came, wait.’
This was the first time in several weeks they had engaged in physical relations. Charlotte’s lips quivered as she laughed with the happiest smile on her face.
“Haah, hah, heuk.”
The situation had reached its absolute limit with lust. It was good to satisfy each other with their mouths, but nothing could compare to this.
Charlotte gripped the bed sheet tightly while facing away from Isaac.
Her expression was furrowed with pain like the crumpled sheet, but Charlotte found that pain infinitely sweet.
Although the expression was a bit odd, at least the “connected” feeling accompanying the pain was something she couldn’t compare to anything.
Of course, the accompanying sexual pleasure was the same. Just in terms of superiority, she valued the emotional exchange with Isaac more.
The bed frame shook repeatedly, and soon the bedroom was filled with the sound of flesh rubbing together and fluids flowing as their bodies intertwined.
“Oppa, ah, heuk......!?”
“......Kk.”
Isaac gripped Charlotte’s hips and probed her. Charlotte, on the other hand, happily accepted being violated like that.
“Huh, this, this is amazing. It’s completely thrilling......”
Beyond that level, the way she moved her body flexibly like a cat made the junction between siblings even more sticky.
Charlotte glanced back and exhaled a lewd breath, and Isaac felt his excitement swell from his little sister’s expression.
Kk!
“......Ah!?”
The following action could be considered a counterattack. When she was licking his penis, she had tied up her flowing hair.
“O, oppa......?”
Charlotte looked back with an expression of endless excitement despite her trembling voice.
And Isaac...... grabbed her hair braided with a blood-red hair tie in one hand harshly.
As if it were a handle.
“Hah.”
Charlotte stuck out her tongue with a flushed expression.
It was a bit embarrassing, but for some reason, the feeling of being held didn’t feel bad... Rather, she was endlessly satisfied that Isaac came out so roughly.
She lay her upper body on the bed to make it easier for Isaac to move, and lifted her hips up. The position created was extremely precarious, however.
“......Oppa, your little sister’s pussy, use it however you want......”
“......”
Such facts were probably irrelevant at least for now.
For Isaac too.
For Charlotte too.
“......You are really.”
In the end, Isaac sighed with a sense of hollowness, but the feeling was not negative.
Soon he pulled her hair with a determined expression.
“Ahk!?”
“That’s right, let’s see how far we can go today. Whether you die first or I die first.”
“Ah, heuk, heeet......!”
And, thud─!
By Isaac’s cock that was thrust in without consideration, Charlotte’s eyes widened, and her eyelashes fluttered.
“......Ah, u, hah.”
And those bloodshot eyes succumbed to lust once. Soon Charlotte slumped with a painful smile......
“Hold your consciousness tightly. Don’t lose it.”
“Yes, eep......?”
Zzzak!!
“──?!”
Isaac had no intention of letting tonight pass normally. Not just sleep, but sex in this twisted sibling relationship was the same.
“Heuk, kuh......!”
Charlotte instinctively lowered her posture and held back tears.
Not that, because Isaac’s hand that lifted her hit her butt.
She glared resentfully at her back with the rising hot pain.
“T, this, what is this......!? Why suddenly, hit, u, ah, hyaang......!”
But she had no time to protest. Isaac seemed to have lost half his reason and was solely devoted to violating Charlotte, and she had no power to stop the intercourse for a moment.
Therefore, behind her was only the desperate mixing of bodies like beasts and exchanging bodily fluids.
“Ah, heuk, hit!? Heueup......!”
Charlotte felt through her burning butt a feeling like ‘I’m about to lose my eyes’, but it was difficult to care about it now.
She was just fresh with the reversed position.
‘This, not, this......’
With her eyes half rolled back, panting for a while, Charlotte melted vaguely without knowing her own state.
......If she wanted, she could have pounced on Isaac anytime. But the reason she didn’t for about a month was simple.
For some reason, if she asked for bed every time, the image would be ruined.
Once she had eaten her oppa, what other image could be more ruined?
There was no such thought, but anyway, she did her best.
She had already given her virginity to Isaac. Since she couldn’t protect her purity anymore, it wasn’t strange to mix bodies for a week, but she had suppressed that desire and lived a normal daily life.
It could be expressed as she showed extremely great patience from Charlotte’s perspective.
It was just that today a somewhat shameless mishap occurred, so things turned out like this, but anyway, she had endured quite a long time.
Therefore, today she was determined to thoroughly torment Isaac, to squeeze him until his body was dried up......
‘That was...... hee.’
The plan failed. It failed miserably.
There were various factors, but the biggest reason was none other than the defeat in that bet.
It would have been greater impact if she couldn’t even imagine the possibility of losing.
‘No, no...... Still, the relationship itself, I have to lead it......’
The grip on the bed sheet was starting to tighten with strength.
As if it were the only support, Charlotte not only used her hands but bit the pillow with her mouth wide open.
Thud, thud......!
The sound of flesh meeting flesh, the sound of fluids seeping out and flowing, and Charlotte’s moans mixed in between.
“Hyaak......! Hup, ek!”
It was the limit. Charlotte intuitively realized that she was approaching her limit, but even so, she couldn’t stop, which was maddening.
“Wait......!? Kyaht?!”
Because this crazy oppa didn’t seem to have even a moment to say ‘wait’.
Charlotte spat out short breaths and tightly closed her eyes.
No more enduring, to endure the thing piercing deepest into her vagina......
“──Ah, hup.”
It came. Like a tidal wave, excessively thick and intense pleasure, sensation, eroticism.
Puh, pyub......!
Charlotte’s waist curved once, and transparent liquid intermittently spurted from between her legs.
“Kk......!”
And quite surprisingly, Isaac also reached his limit around then.
With his brows furrowed, he gripped her sister’s hips and the lower part of her waist even more strongly with a fiercer grip.
“Ah, wait, now, not......?!”
Charlotte had to jerk her body at the moment she was still feeling the afterglow of orgasm.
The rough breath from behind her oppa, the violent penis inside her belly, that instinctive feeling that something was about to come out.
Ulk, ulk!!
“......Ah.”
The problem occurred right then.
Charlotte had been able to prepare her mind just in time, but the heat that should have filled her inside was so weak that it could barely be felt properly.
Charlotte blinked slowly and looked back slowly.
Isaac’s expression was, needless to say, that of a man who had just reached climax.
“No...... why.”
Something that should have been felt was not felt. She was tense, but the hot liquid she had been secretly expecting didn’t pour out.
“......Ah, chew.”
Charlotte distorted her expression for a moment, then naturally figured out the cause.
It wasn’t Isaac’s seed, but there was a foreign sensation felt inside her belly.
She immediately set her eyes on fire and glared at Isaac sharply.
After a moment’s hesitation, Isaac Havertz trembled.
“......Why, why?”
After venting his frustration, his mind was amazingly cold.
To that extent, the rough behavior until just before came to mind belatedly.
“......Really, it doesn’t suit me. Condom.”
“Eh?”
“You didn’t feel it, didn’t feel it......! Shit!”
Charlotte yelled loudly as if the only complaint was that Isaac’s milky liquid hadn’t entered her belly.
She then glared sharply at Isaac and growled in a low voice.
“......Give it.”
“......What?”
“Condom. That one filled with oppa’s semen right now.”
“Eh......”
Isaac was momentarily doubtful if he had heard correctly. Was he saying to give the condom now?
He blinked once and asked back with sincerity.
“......Why? What are you going to use it for?”
It was hard to predict the use, but unfortunately, the timing of the question was not good.
Charlotte put a bloody aura on her fingernails with a fierce expression.
“Shall I take it and give it back, or give it nicely?”
“......”
Isaac closed his mouth and secretly looked down at his lower body.
Then he hesitated for a moment, but actually, there was no problem to consider.
She told him to give it, how could he refuse the command? Isaac honestly pulled out his penis and took out the swollen condom.
Huk!
“......Ah.”
Charlotte, who had been watching the whole process fiercely, immediately snatched the condom.
She looked at it with cold eyes, then suddenly stood up.
“I’ll sleep alone today.”
“......Eh, eh?”
“Good night, oppa. Dream well.”
And after roughly putting on the clothes she took off, she left the bedroom immediately.
The declaration(?) of separate rooms that was made without room to speak, Isaac could only stare at the entrance of the bedroom with a dazed expression.
The only question in his mind was.
‘Where the hell am I going to use that......?’
The location of the suddenly stolen condom.
Only that.
