Chapter Index

    449

    Sister Se-hee sits demurely, her face flushed and her eyes lowered.

    As if she knew Si-woo would come to her room, she is not greatly surprised or startled to see Si-woo naked.

    Like the other family members, Sister Se-hee has a purple dog collar from the department store around her neck.

    Judging by the smooth skin visible through the gap in the blanket wrapped around her, Sister Se-hee must also be naked like Si-woo.

    Ever since she came up to the second floor with her friends while Si-woo was out taking Mom…

    Sister Se-hee was definitely keeping the newly established rules of the house.

    “Y-you came?”

    Sister Se-hee awkwardly speaks first, seeing Si-woo naked.

    Si-woo ignores Sister Se-hee’s words and walks straight to the bed where she is.

    “Lie down! I’m going to put it in right now!”

    Si-woo said to Sister Se-hee, showing off his huge, hard penis as if to flaunt it.

    “R-right now?”

    Sister Se-hee asks, reacting as if she is a little flustered by Si-woo’s command.

    “Of course it’s right now! You fucking bitch! You did everything with Shin-bi and So-ra, why are you acting innocent now?!”

    Si-woo speaks to Sister Se-hee in a sharp voice, as if scolding her.

    Hearing Si-woo’s voice, which seemed to be reproaching her, Sister Se-hee shrinks back as if frightened.

    “Se-hee, you’re going to keep being wet, aren’t you?! I can do to you what I did to Shin-bi and So-ra earlier, you know? But I’m holding back as much as I can right now! Hurry up and spread your legs and lie down!!”

    Si-woo commanded Sister Se-hee in a voice that seemed to be suppressing his emotions as much as possible.

    Sister Se-hee hesitates for a moment, then pushes the blanket aside.

    Sister Se-hee’s smooth and dusky, seductive naked body was revealed to Si-woo.

    The hickeys all over her body seemed to stimulate Si-woo’s excitement and desire even more.

    Is it Si-woo’s imagination that there seem to be more hickeys than when he saw her during the day?

    Sister Se-hee reveals her naked body to Si-woo and lies down on the bed.

    Sister Se-hee covers her face with her arm and spreads her legs apart.

    Her large breasts and intimate crotch were being shown to Si-woo head-on.

    “Haaahhhhh…”

    From Sister Se-hee’s mouth, who had finished preparing for intercourse, a hot, sobbing moan came out.

    From her legs, which were spread wide open in a defenseless state, a subtle tremor was created.

    Si-woo had no intention of using a condom during the sex he was about to have with Sister Se-hee.

    He had promised Mom to always use contraception when having relations with other family members, but he thought it would definitely be a hindrance to his sex with Sister Se-hee to gain peace of mind right now…

    Mom won’t come up to the second floor to see Si-woo and Sister Se-hee having sex.

    Besides, he was already used to ejaculating inside Sister Se-hee.

    Even if Sister Se-hee gets pregnant, he can make the excuse that it was because of the previous unprotected sex.

    Even if Mom finds out, what more can Mom say to Si-woo now?

    **

    Si-woo kneels between Sister Se-hee’s spread legs.

    As expected, Sister Se-hee had already soaked her crotch and thighs with her fluids.

    The tattoo “BS” is clearly visible on the inside of Sister Se-hee’s thigh, covered in fluids.

    The initial tattoo of Sister Shin-bi, who lost her virginity to Si-woo today.

    Si-woo gripped the shaft of his penis and brought the tip of the shaft to the initial tattoo between her spread legs.

    The pre-cum flowing from the tip of his penis was mixing with Sister Se-hee’s fluids and being applied to Sister Shin-bi’s initial tattoo.

    Si-woo rubs the smooth skin above the letters in a circular motion with the tip of his glans.

    Sister Se-hee’s tremors were gradually increasing, as if urging Si-woo to penetrate her.

    Sister Se-hee’s knees and thighs, narrowing and widening inwards.

    Si-woo brings his shaft to her parted crack.

    Si-woo aligns the tip of his glans with the gap in the crack and slowly pushes his pelvis forward.

    Squish!

    Si-woo’s penis slowly slides into Sister Se-hee’s slippery vagina.

    “Haaahhh…Haaa… Hoo…”

    Sister Se-hee moans as if fully feeling Si-woo’s penis, which is slowly stroking her sensitive flesh as it penetrates her.

    Si-woo’s penis could be felt pushing open the narrow hole and reaching the entrance to her uterus.

    Si-woo leans his upper body forward and covers Sister Se-hee’s body, pressing against the entrance of her uterus.

    At that moment, Sister Se-hee brings her legs together, which had been spread apart, and wraps them around Si-woo’s waist.

    Si-woo and Sister Se-hee’s bodies are pressed closer together.

    Si-woo’s lips were touching her shoulder and neck.

    Si-woo opens his mouth wide and brings his lips to Sister Se-hee’s neck.

    “Suck!”

    Si-woo makes the inside of his mouth a vacuum and sucks the muscles and flesh of her neck.

    “Haa Haaa Hnnng…Hnnng…”

    Sister Se-hee lowered her arm, which had been covering her face, and wrapped it around Si-woo’s head, moaning.

    With just that simple caress and pressure, she stiffened the arms and legs with which she had embraced Si-woo and was shaking her body.

    Sister Se-hee, twisting the body under Si-woo finely, and at the same time reflexively tightening her vagina.

    Along with her arms and legs, the temperature and slippery sensation inside her vagina seemed to completely embrace and wrap around Si-woo’s body.

    He could have pushed his penis all the way in and brought his lips up to her ear, but Si-woo didn’t overdo it and just maintained that position for now.

    Just doing that seemed to relieve some of the tension, anxiety, and unpleasantness that had been filling Si-woo’s chest.

    Si-woo pushes Sister Se-hee’s legs, which are wrapped around his waist, down below his pelvis.

    Then, he lifts his waist slightly and moves his lips from Sister Se-hee’s neck to her breasts.

    Si-woo sucks on Sister Se-hee’s nipple with his lips and presses his face into her breasts.

    Si-woo is sucking on her breasts while his penis is inserted into Sister Se-hee’s body, arching his back.

    “Suck Sluurp Suck!”

    Si-woo sucks on Sister Se-hee’s big breasts as if a baby is sucking on its mother’s milk.

    “Haaa…Hnnn….Haaa”

    Sister Se-hee moans, wrapping her arms around Si-woo’s head, who is sucking on her nipples like a baby.

    Si-woo grabbed the opposite breast with his hand from the one he was sucking on with his mouth.

    Si-woo sucks strongly on Sister Se-hee’s nipple with his mouth, and at the same time vigorously massages her other breast.

    In addition, Si-woo moves his pelvis back and forth slightly, and begins to gradually rub the shaft of his penis that is inside her vagina.

    “Haaa…Hnnn…Hwoo!”

    Sister Se-hee’s calves and heels wrapped around Si-woo’s thighs like snakes.

    Sister Se-hee’s legs, repeatedly pulling and releasing, as if keeping pace with Si-woo’s waist movements.

    Si-woo’s penis was repeatedly touching and leaving Sister Se-hee’s uterus, constantly thrusting inside her vagina.

    Sister Se-hee’s nipples and breasts, which were being rubbed and changing shape.

    It wasn’t a violent or fast movement, but Sister Se-hee, who was being relentlessly targeted in three places at the same time, soon trembled as if she had reached her climax.

    Si-woo stopped moving, pushing his penis deeply into her vagina, so taut that her uterus was being pushed up.

    “Haaahhh Haaa…Haaahhh!”

    A sobbing moan could be heard from Sister Se-hee’s mouth.

    Her legs had already come back up and were tightly wrapped around Si-woo’s pelvis and waist.

    Thwack thwack thwack!

    Although he didn’t feel the sensation of ejaculation, Si-woo slammed his penis into Sister Se-hee’s vagina, as if shaking off his semen.

    “Hnnng haack haaa!”

    Sister Se-hee wrapped her arms and legs around Si-woo’s body as if accepting Si-woo’s ejaculation, and squeezed her vagina tightly.

    Sister Se-hee shakes her pelvis back and forth with almost instinctive sensations.

    Even after she reached her climax, Si-woo continued to suck on her breasts and massage them while continuing to penetrate her.

    Si-woo continued to lick Sister Se-hee’s nipples until her tremors and afterglow subsided.

    He continues to caress the opposite breast with his hand that was covering it.

    **

    Before long, Sister Se-hee’s tremors had subsided.

    Although it was uneven and disorganized, her breathing seemed to have returned to a somewhat calmer state than before.

    Si-woo also seemed to have regained some stability while sucking on Sister Se-hee’s breasts.

    Si-woo loosened the pressure on his pelvis and slowly took his lips away from Sister Se-hee’s nipple, where he had been burying his face and sucking.

    Si-woo looked up as if to check on her condition, while holding Sister Se-hee’s breast with one hand.

    Sister Se-hee’s arm, which had been wrapped around Si-woo’s head, had already gone back up and was being used to cover her face.
