    (Shinbi Older Sister)

    391

    “…That…that day?”

    Shinbi Older Sister, receiving Siwoo’s caresses, echoed back as if reacting to Siwoo’s question.

    “I mean the day of the group blind date. We both came out of the room cafe first. And then I put Shinbi in a taxi and sent you home…and I went back to the room cafe because of Sehee Older Sister…”

    Siwoo tries to remind Shinbi Older Sister of what happened that day.

    “Oh…that day…Thanks to Siwoo putting me in a taxi…I got home safe.”

    Shinbi Older Sister answered awkwardly as if the events of that day had suddenly come to mind.

    Siwoo turns Shinbi Older Sister toward the bed, and then brings the hand that was gripping her buttocks to Shinbi Older Sister’s crotch.

    Shinbi Older Sister reflexively flinches and pulls her waist and pelvis back as Siwoo’s hand touches the front of her crotch.

    Siwoo brings his pelvis to Shinbi Older Sister’s butt, preventing Shinbi Older Sister’s butt from moving backward.

    A huge penis pillar fits between Shinbi Older Sister’s butt cheeks.

    Siwoo checks Shinbi Older Sister’s panties, which are damp with moisture, with his hand.

    “I heard from Yena that you got home safe…”

    Siwoo mentions Yena Teacher’s name without honorifics, as if subtly probing.

    “Ah…yes…did…did she?… ”

    Shinbi Older Sister reacts nervously as Yena Teacher’s name comes out of Siwoo’s mouth as if speaking informally.

    “Yena is your aunt, right? Seulgi said that when I went to the academy for counseling before?”

    Siwoo asked to clearly confirm the relationship between Yena Teacher and Shinbi.

    “S…Seulgi? Haa…th…that’s….yes…corr…correct…my aunt…”

    Shinbi Older Sister answers as if troubled by Siwoo’s questions and actions.

    Then, Siwoo presses down on Shinbi Older Sister’s pubic bone with his palm and presses his pelvis against her buttocks.

    Pleasure spreads as if squeezed out by being pressed against the penis pillar.

    “Did you hear about what happened after you left…from Sora and Sehee?”

    Siwoo asked as if trying to confirm whether Shinbi Older Sister knew exactly what had happened that day.

    “Yes…I…I heard…that you and…the older brothers…fought and went to the police station…”

    Shinbi Older Sister answers with her buttocks and crotch pressed down by Siwoo’s penis and palm.

    “The mothers came to pick us up from the police station…Instead of our aunt, your aunt came to pick up our guardian…”

    Siwoo speaks to Shinbi Older Sister as if explaining what happened that day.

    “Isn’t it strange? It wouldn’t be easy for people who aren’t family or direct guardians to take custody of kids who caused problems and were caught by the police and take them out…”

    Siwoo speaks as if raising suspicion about the identity of Yena Teacher, who took them into custody and took them out of the police station as a proxy, even though they were not blood relatives or guardians.

    “……”

    Shinbi Older Sister is careful to answer the suspicions raised by Siwoo, and remains silent, closing her mouth after trying to say something.

    Siwoo puts strength into the fingers he had placed over Shinbi Older Sister’s thin panties, causing his fingers to enter her groove along with the fabric of the panties.

    The middle finger is buried inside Shinbi Older Sister’s groove along with the front of the wet panties.

    “Haaheueut…S…Siwoo…j…just a moment…”

    Shinbi Older Sister squirms and twists her body as if trying to stop Siwoo’s violent behavior.

    Siwoo’s hand, which had been placed between the triangular valley at the front of Shinbi Older Sister’s panties, falls.

    -Slap!

    Siwoo lifts his hand, which had fallen from her panties, and hits her butt.

    “Haaheueuk!”

    Shinbi Older Sister lets out a groan as if surprised and in pain.

    “Get up on the bed, put your hands down, and lie down!”

    Siwoo lowers his voice and commands Shinbi Older Sister in an imposing manner.

    “S…Siwoo…I’m…I’m doing this…f…for the first time…”

    Shinbi Older Sister speaks to Siwoo in a pitiful voice, as if asking him to do it gently.

    -Even though you’ve already been making out and rolling around with Sehee Older Sister…-

    “Get up on the bed! I said put your hands down and lie down!!”

    Siwoo repeats the same words in a dry tone, as if ignoring Shinbi Older Sister’s words.

    “Haaaa…”

    Shinbi Older Sister lets out a long sigh of frustration at Siwoo’s stubborn command.

    Shinbi Older Sister soon gets on the bed and lies down on all fours, as if she can’t help it.

    Shinbi Older Sister lying on the bed wearing only panties and a bra.

    Shinbi Older Sister’s voluminous breasts were shaking under the bra that was lifted up.

    The groove of her buttocks and wet crotch, barely covered by thin, small panties.

    Siwoo pulls down her panties covering her buttocks and crotch, as if trying to balance Shinbi Older Sister who is up and wearing a bra.

    Shinbi Older Sister’s thin panties come down to her thighs under her buttocks and get caught.

    Her snow-white buttocks and neatly trimmed crotch are exposed.

    Her bra and panties, slightly out of place from where they should be, are like an installation art piece arranged by meticulous calculation.

    Shinbi Older Sister’s body is trembling as if she is ashamed.

    Her buttocks, which are twitching and tensing, and her breasts, which are shaking downward, make Siwoo’s penis even harder.

    Siwoo gets on the bed and takes his place behind Shinbi Older Sister.

    Siwoo aligns the tip of his erect penis with her parted groove.

    Siwoo parted Shinbi Older Sister’s vulva with his glans and spread it to the left and right as if rummaging through it.

    Her vaginal fluids are added to Siwoo’s penis, which was wet with pre-cum, and applied.

    Siwoo pushes his pelvis forward slightly and pushes the tip of his penis into her hole.

    -Squeak!

    Siwoo’s penis enters between Shinbi Older Sister’s split flesh.

    Siwoo feels something like a membrane blocking the insertion at the tip of his penis.

    Probably the fibrous membrane that proves Shinbi Older Sister is a virgin.

    Feeling the tension of the fibrous membrane, Siwoo tries to push his penis in by putting strength into his waist until the precarious moment.

    “Haaheueueut!”

    Shinbi Older Sister groans in agony, bringing her thighs together while lying face down.

    “Slap!”

    Siwoo spanks her butt once again, as if telling her to relax her body.

    “Haaheueut!”

    Shinbi Older Sister’s body, which was lying on the bed mattress and supporting herself with her knees and hands, was trembling.

    Siwoo grabs Shinbi Older Sister’s waist with both hands, pushes his pelvis forward, and forcefully shoves his penis with the glans on the entrance of her vagina.

    -Thududuk! Thuk!

    A sensation like a membrane breaking is transmitted from the tip of Siwoo’s penis.

    -Swooshing!!

    Siwoo’s penis pierces the fibrous wall blocking the insertion and pushes into Shinbi Older Sister’s vagina.

    “Haaheueueueuk!”

    Shinbi Older Sister bends her waist and upper body to match the shape of Siwoo’s huge penis entering her body.

    Siwoo waits for her body tremors to subside with about half of his penis pillar inside Shinbi Older Sister’s body.

    “I was thinking about it alone. What would have happened if I had come out separately with you that day and not gone back to Sehee…?”

    As Shinbi Older Sister’s tremors subside, Siwoo opens his mouth and begins to speak as if to himself.

    “Without knowing that the older brothers drugged and raped Sehee, I would have been having fun having sex with you instead of Sehee, right?”

    Siwoo is putting the thoughts that were flowing through his head into concrete words.

    Siwoo was informing Shinbi Older Sister that he had sex with Sehee Older Sister by deliberately adding the words ‘instead of Sehee’.

    “Haaaa…!”

    Shinbi Older Sister, instead of answering Siwoo’s words, breathes heavily and tightens her vagina.

    -Slap!

    Siwoo slaps Shinbi Older Sister’s butt as if to tell her to release the tension in her vagina.

    “Haaheueuk!”

    Shinbi Older Sister tenses her butt muscles as if surprised, and then gradually consciously releases the tension in her vagina.

    “When you brought the birth control pills that time, you knew about it, right? That I had sex with Sehee!!”

    Siwoo was asking as if he had caught a clue to the pursuit that would pierce the hole of suspicion.

    “You knew everything, right!? About me doing perverted things while Seyoung was sleeping, and having sex with mom! That’s why you ran away with Seyoung to Aunt Seonju’s house!”

    Siwoo lays out his secrets and asks Sehee Older Sister as if cornering her.

    “……Haaa……Haaa……Haaheueue….”

    Shinbi Older Sister closes her mouth once again and is panting heavily.

    “You also knew that I had sex with Aunt Seonju and Cheoljin’s mom, right? You were sharing all the smartphone content, right?”

    Siwoo speaks as if exposing the contents of the part that Shinbi Older Sister is reluctant to talk about.

    Siwoo continues to ask questions as if forcing Shinbi Older Sister to answer and pressing her.

    “Heueue…Heueueut…”

    Shinbi Older Sister was letting out a sob-like groan.

    Shinbi Older Sister’s vagina tightens once again.

    -Slap! Slap! Slap!

    Siwoo violently slaps the butt of Shinbi Older Sister, who has no answer, with both hands.

    “Haaheueuk Haaat Haaheueuk! I…I knew! …Ah…it hurts! Heueuk…”

    Shinbi Older Sister answers with honorifics mixed in, as if spitting out the truth because she is in pain.

    At that moment, Siwoo recalls the image of Sooah, who had been trained by Aunt Seonju since she was a child.

    As expected, Shinbi Older Sister seemed to know a lot about Siwoo and his family’s secrets.
