4 Second Sister Baek Min-ah 2 (18+)

4 Second Sister Baek Min-ah 2

The precarious tightrope walk, begun under the major premise that I mustn't cum, continued. 

"Oof...my little brother's dick is really big, isn't it? It doesn't even cover it all with my breasts. Would it take someone like Mom to do it?" 

Min-ah said, cupping my stiffly erect dick with her breasts. 

Even saying that, her breasts are also tremendously large. Despite having no excess fat on her body like an athlete, her breasts are still plentiful. 

Rub rub 

They are soft, but also so bouncy that I wonder how she manages them. Is that level of elasticity even possible at that size? I almost wanted to poke them with my finger. 

"Looks like I don't even need lube? Just how much precum are you leaking, you rascal?" 

Squelch squelch 

Because she was squishing her breasts this way and that as she spoke, my dick was pleasantly bent. 

"I don't even need to spit..." 

"Sp-Spit on me!" 

"Wh-What? Pfft, hahahaha. Who raised you to be such a pervert? Keke, would you like your sister to spit on your dick and rub it with her breasts?" 

Min-ah was momentarily flustered, but soon wore a seductive smile. Who could resist such a pretty sister coating their little brother's dick with spit and rubbing it with her breasts? 

Nod nod 

"Heung, what should I do? Are you sure? You'll regret it... Beee♥" 

Min-ah said, flicking her tongue. 

Her red tongue, like a ripe apple, stuck out long. Saliva slowly dripped down from the tongue wriggling in the air, wetting her cleavage. 

Drip 

And the dripping saliva stained my dick, which was lodged between her breasts, with her scent. 

"Ah, spit might still be dangerous for you...I can't help it. It was just a little too dry with just precum." 

Min-ah spoke as if it were an accidental occurrence. It was then that I understood the meaning of what she had said. 

"Wh-What?" 

My dick is hot. The milkers, which were already so soft they were driving me crazy, felt even more sensitive. 

"You see, my spit is... the best aphrodisiac?" 

It was as if she was saying, 'Now you're dead.' 

"W-Wait, I didn't know! Anna didn't have anything like that!" 

"It's my ability...♥ Try your best to endure this time too. You have to strip my bottom half, right...♥?" 

Squish squish squish squish 

"Haa, haa. Ji-han, how is it? How is it to have me, your sister who you've been peeping at every day, milk your dick with her breasts?" 

"Th-That...hnnng, don't ask..." 

"You have to be honest? Did you forget?" 

"I-I like it too much!" 

One of the few conditions they demanded: Never tell a lie. 

When I first heard that condition, I wondered if they didn't trust me. I even felt a little sad. 

But I could now realize the true nature of this condition. 

To watch my reactions as they mingled with me, and to enjoy hearing those reactions directly from my mouth. 

The sight of me struggling and panting from the pleasure the succubi offered would be a good seasoning for them. 

However, the attempt to turn away from the pleasure while continuing to think came to naught. 

Squeak! Squeak! Squeak! Squeak! Squeak! 

Besides the softness that covers the entire dick shaft, a hard texture brushes against the most sensitive part below the glans. 

Startled, I raised my upper body, and saw my sister rubbing her nipple against the glans. 

"Haa, haa... how is it, Ji-han... do you like it?" 

I was the one clearly being caressed, but somehow she was sweating and breathing heavily. 

The strong pheromones emanating from that sweat, the mental satisfaction felt from the fact that she was aroused. 

These, along with the dizzying softness felt from my dick, synergized to inject pleasure directly into my brain. 

"Sis, only 5 minutes... hnnng, left." 

Perhaps my reason was paralyzed by the pleasure, I didn't expect that my sister would become impatient after seeing the remaining time and that the intensity of her caresses would increase. 

It was just a word I spat out with the satisfaction of having endured this much against a strong-willed beauty, but in the end, it was a huge mistake. 

"Okay, then." 

My sister started to put on her top, leaving her underwear on. 

"What are you doing?" 

Time is still passing. There's no way that sister, full of competitive spirit, would give up the bet, right? 

I felt a growing anxiety while enjoying the rain-like rest. 

Swoosh 

And she, with the top on, put her breasts on my dick again. She didn't say anything either, but that silence was scary. 

"S-Sis, what are you trying to do?" 

Despite my question, she steadfastly embraced my dick and tightly tied the clothes at the bottom of her breasts. 

Then she took a stance. 

Smirk 

"To do this." 

It was a mischievous smile, but perhaps because she was such a sexy beauty showing off her healthy beauty... 

Rather than a mischievous feeling, I only felt the urge to fuck her right away. 

Of course, that was only possible in my imagination, as I could get my ass kicked if I did that. 

The sister, who almost made her little brother a rapist, calmly took a breath and then... 

"...! Ooh!" 

Squeak Squeak Squeak 

Rub Rub 

In that state, she started shaking her breasts in all directions. 

From left to right, from top to bottom, and diagonally. 

Sometimes she shook them in the shape of an eight, and sometimes she moved them simply up and down. 

Even the knot that tied the clothes rubbed against the shaft of my dick, contributing to the pleasure. 

'This is the real hydraulic press!!' 

My dick, not only buried between bouncy and large breasts, but also fixed with clothing. 

An enormous tightness was felt. 

"How are my boob pussy? ...♥!! Look at you not even being able to talk because you like it so much...♥." 

Squelch Squelch Squelch! 

A mystical boob dribbling with a different footwork. 

It bent to such a dangerous angle that a dick fracture should be worried about, but under the succubi's management, my dick had become even harder and more elastic, so there was no problem... Look at it now too. 

"Haa, haa... how is it? Isn't it awesome? ...♥" 

Every time her breasts heaved, my dick was bent this way and that, but only pleasant pleasure was conveyed. 

"Haa, I'm asking you how it is? Do you like it? Huh? You like it, right?" 

Min-ah persistently asked. Even madness could be seen in her eyes. 

It was as if she would kill me if I didn't say it was good, even if it was a lie, but even if she didn't ask with such a grim expression, I would give the answer she wanted. 

"Yeah, I like it too much! Of all the things I've felt since, hnnng, I was born, keuek, the most!" 

Was my appearance, steeped in pleasure, that pleasing to her? I could feel her leggings getting wet. 

"Hehe, you, you're gonna cum if you force yourself to hold back? Give up around here!" 

Squelch Squelch Squelch♥ 

Wham Wham Wham! 

This time, she started jerking me off, repeatedly hitting her big breasts against my lower body. 

Every time Min-ah's heavy underboob hit my pubic bone, a throbbing pleasure rose from the root of my dick, giving me goosebumps. 

The pleasure that started from my dick spread beyond my dick and all over my body. 

"Keueut, I'm really... cumming...!" 

"Yeah, cum, I said cum...♥, cum, cum! Thick dick juice, cum all over my breasts...!!" 

While hearing Min-ah's voice demanding dick juice, I felt semen rising from my balls. 

Beep beep! Beep beep! 

The timer rang with good timing. I barely managed to push the jizz that had pushed up to my glans back down again. 

"Haa, haa. I almost came for real." 

"Aah, I lost again." 

I was sure victory was right in front of her nose. My sister's expression wasn't particularly dark for having lost. 

In fact, it may have been even more so because it was a game where the distinction between victor and loser was meaningless. 

"Now take off your pants, Sis. If I take off your underwear, I win, right?" 

"Sigh, you wanted to see Sis's pussy that much? Then until the end... huh?" 

Min-ah said, taking off her pants. 

Because she turned around and bent over to take them off, her buttocks and pussy, wrapped below, were visible at a glance. 

Her pussy was also a deep pink color, like her nipples. 

'Huh? Why is her pussy visible when she only took off her pants?' 

"S-Sis, what about your underwear?" 

Then she smiled as if she had forgotten. 

"Ah, I guess I forgot to put on panties. Oh well. Since there are no more clothes to take off, let's say you won. You want to lick Sis's pussy? Go ahead and try." 

-Since you want to lick it so much, I'll let you lick it. 

The sister's attitude, pushing me away on the bed and confidently occupying my dick, gave off that nuance. 

'Did she foresee even this far into the future?' 

Given her personality, it would have been a little embarrassing for her to ask me to lick her pussy. 

Even if she had forcefully ordered me, I would have licked it deliciously. 

She stimulates me under the guise of a game. Then I will naturally feel a sense of rivalry. 

Although she said it was a mistake, it was clearly Min-ah's defeat, as she was now naked. 

It seemed that she judged that I, burning with a sense of rivalry, would start eating her out without regard for anything else. 

Was she inducing me to lick her voluntarily, instead of directly ordering me to lick her? 

'What a scary succubus.' 

I thought she was a strength-based character, but was she actually intelligence-based? Her intelligence might rise only for sex. 

Well, either way, I wasn't going to kick away the opportunity that had come. 

Just let me cum already! 

The sound of my dick pleading came, so I patted it gently and approached my sister. 

'It's not just you who's having a hard time. Just bear with it a little longer.' 

"Okay, there's plenty of time. Take your time." 

In the meantime, Min-ah was lying down with her arms and legs spread open. 

Even in a lying position, I could see her face without humiliation and her breasts maintaining a pretty shape. 

I almost lost my mind and stuck my dick in her, but I managed to barely hold back because the other party was Min-ah. 

Because she could genuinely beat me up and it wouldn't be strange. 

'Shall I taste every nook and cranny?' 

I took my place between her legs as if I were having sex. 

I naturally reciprocated my waist so that her clitoris would rub against the shaft of my dick. 

At the same time, I approached her face with my hand and stroked it. 

Rub rub. 

"...? What are you doing?" 

It was my sister whose expression, full of anticipation for the pleasure to come, had crumbled. 

"Because you're so pretty. When else would I get to touch my sister's face? You gave me permission to do whatever I want, so I'm just trying it out. Should I stop if you don't like it?" 

"Heung…♥ Okay, a bet is a bet, so do whatever you want." 

Fortunately, it seemed that she liked my answer. She snorted in satisfaction and looked at me gently stroking her face. 

In fact, my appearance is also not inferior to that of a succubus. Of course, it wasn't like that from the beginning, and it has changed a lot as I've lived. 

Is it thanks to that unidentified tea? 

Thanks to that, when I went to school after the vacation, I heard a lot of people saying that I had plastic surgery. 

There was also that reason for going to schools far away each time I advanced. 

And one of the pieces of information I've gained from living with succubi for half my life is that there are no people as sensitive to pleasure as them. 

As such, they say that elements that are important to pleasure, such as the face, body, and dick, are areas that can never be conceded. 

Thanks to that, I became a modified artificial human according to the tastes of the succubi, but I could never complain. 

'She seems to like it.' 

Judging by the way she's staring at me so intently, my face must be exactly the same as her taste, or at least quite similar. 

Was it because of that rising confidence? 

The hand that had been gently stroking her face rubbed against my sister's lips. 

Rub rub 

Her lips were as soft as they looked. 

I wondered what they would taste like. 

Without even knowing that a faint blush had formed on my sister's face, I brought my face closer. 

"Peck." 

Only lips touched lips lightly and then separated. 

"That was my first kiss, how was it for you, Sis?" 

I asked, feeling proud that my sister didn't avoid my face either, but there was no particular answer coming back. 

Instead. 

Whoosh. 

A brilliant golden mist, the same color as her hair, enveloped her body. 

"...Wow." 

The pretty woman remaining in the place where the smoke had disappeared was still Min-ah herself, but there were also changed parts. 

The goat horns that I thought would be perfect as handles if I grabbed them without thinking. 

The heart-shaped tail protruding from the vicinity of her buttocks and shaking this way and that. 

The uterine tattoo faintly flashing like a dying battery on her lower abdomen. 

The succubus, who revealed her true form for the first time, was truly, terribly beautiful. 

"You call that a kiss?"
