    A feeling like an invertebrate annelid, covered in mucus, is crawling on the skin of my butt.

    Se-young’s tongue licked the flesh around my butt, then at some point, started moving toward Si-woo’s anus, which Soo-ah was sucking.

    Se-young’s tongue, erected like a sting, burrowed into the hole between Si-woo’s butt cheeks.

    Se-young’s tongue touched Soo-ah’s tongue, which was licking Si-woo’s anus.

    The sisters’ tongues touched and stuck together, crisscrossing up and down, and began to rub against Si-woo’s anus.

    A grotesque sensation, as if two earthworms were burying their heads in the anus and wriggling, traveled up Si-woo’s tailbone to the back of his neck and resonated.

    Si-woo’s buttocks, wet with saliva, and the two younger sisters’ hot breaths, playfully exhaled into the hole.

    Si-woo was feeling what was happening behind him, unseen, solely through the sensations of his anus and buttocks.

    Si-woo’s sphincter tightened strongly once again.

    Si-woo’s waist bounced up so much that his upper body lifted.

    Si-woo writhed his waist from side to side, curling his toes as if he was losing his mind from the anilingus his two younger sisters were giving him.

    With a sensation that felt like his brain was melting, Si-woo’s hand, gripping Se-young’s neck, trembled strongly as if vibrating.

    The trembling soon spread throughout Si-woo’s body, reaching his lifted upper body, his calves below his knees floating in the air, and the tips of his toes.

    “Hngh!”

    Unable to bear it any longer, Si-woo let out a loud moan at the rimjob Se-young and Soo-ah were giving him.

    From below, out of Si-woo’s sight, Se-young’s laughter seemed to be heard as she chuckled softly at Si-woo’s reaction.

    Se-young’s laughter was so small that it was almost drowned out by the mouth sounds, making me wonder if I had misheard.

    “Ugh…!”

    Si-woo let out a short groan at the sensation of Se-young’s fluid tongue movements and hot breath felt in his anus.

    Se-young’s technique was so dazzling that it was enough to divert Si-woo’s nerves and attention from her laughter.

    Se-young’s unusually persistent tongue play focused Si-woo’s mind entirely on his unseen back hole.

    Feelings such as shame and humiliation flooded up Si-woo’s back toward his chest and neck.

    The shame of being played by his sisters…, especially Se-young, was making Si-woo’s body curl up.

    But with the mysterious and new sensation of pleasure felt from behind, there was no time to dwell on such feelings or sensations for long.

    Si-woo had been making his family commit all sorts of perverted acts that seemed to cross the line for the past few days.

    He clearly remembered sucking Sun-joo aunt’s ass before, but this was the first time he had his anus licked like this.

    Moreover, it was a new form of caress that he received voluntarily from Se-young and Soo-ah, even though there was no command or request from him.

    The caress was raising Si-woo’s senses to a different level of sensitivity than before.

    The unfamiliar and intense stimulation that traveled up the spine from the back hole, awakening all the brain cells, was making Si-woo lose his sense of the relationship and reality even more.

    The two younger sisters’ small, soft tongues burrowed more and more intensely into the anal wrinkles, as if they were competing to get into his anus.

    Soon, Soo-ah, seeing what Se-young was doing, followed suit, putting strength into her tongue and caressing Si-woo’s anus even more persistently.

    The two younger sisters’ tongues penetrated so intensely that it felt as if they would be completely engraved on Si-woo’s anus with a complete sensation.

    Si-woo gritted his teeth and endured the sisters’ caresses while trying to suppress his moans.

    Si-woo momentarily imagines all the family members he has had relations with licking his anus like Se-young and Soo-ah.

    Just as the scenes of new rituals and play with his family were about to become more concrete in his mind…

    Another unfamiliar sensation covers Si-woo’s anus.

    This time, it wasn’t the sensation of putting a tongue into the hole.

    “….!!!! …Ugh…!”

    Si-woo gasped briefly, startled by the dizzying suction that seemed to completely cover his anus and the surrounding area.

    What Si-woo felt behind him was a powerful vacuum-like suction, as if sucking air into the mouth to squeeze something out.

    The sensation that felt like lips were opened and placed around the anus, covering it, and sucking as hard as possible, was being felt in Si-woo’s anus.

    Si-woo could tell that it was Se-young who had pushed Soo-ah away and covered his anus with her lips, sucking the flesh inside the hole, without having to look back.

    Se-young was using the powerful suction in her mouth to suck Si-woo’s anus as if she was squeezing it out.

    “Chyuuup, chup! Chyuuup, chup!”

    The intense mouth sounds that Se-young was making from Si-woo’s back hole.

    Si-woo felt a thrill and goosebumps on the skin around his back and neck at Se-young’s actions, as if she was trying to completely occupy his anus.

    Her caress was making Si-woo fall into an even stronger climax and a state of special exhilaration.

    Si-woo was heading towards a climax of sensation that made his vision blur, as if he was about to have his anus pulled out.

    Abnormal excitement and convulsions washed over Si-woo’s entire body.

    A second climax, like a woman’s orgasm, arrived relentlessly.

    Seeing Si-woo’s reaction, Se-young stopped the vacuum-like suction she was making with her mouth and took her lips off Si-woo’s anus.

    Only then did Si-woo relax as if the tension had been released, and he buried his face on Sun-joo aunt’s chest.

    Soo-ah, who had been pushed away by Se-young and had her spot taken away for a while, put her tongue on Si-woo’s empty anus as soon as Se-young took her lips off.

    Soo-ah diligently caressed Si-woo’s anus and its vicinity with her own soft tongue movements.

    Si-woo relaxed his body once again as if he was relieved, and he was fully feeling the cozy and soft touch of Soo-ah’s tongue with a languid feeling.

    “Churuup!”

    At that moment, a hot and moist sensation that seemed to envelop his balls was felt from below, where his vision was limited, along with a violent mouth sound.

    The sensation of Sun-joo aunt’s smooth vaginal opening felt on my penis, and the cozy and delicate sensation of Soo-ah’s tongue felt on my anus.

    And a new sensation that seemed to be added in between.

    Se-young put Si-woo’s ball sack in her mouth and began to suck it with a powerful suction, just like she had done to Si-woo’s anus a moment ago.

    At the same time, Se-young was rolling Si-woo’s testicles violently using her tongue, lips, and teeth.

    A mixed sensation of tingling, stinging pain and extreme pleasure was transmitted from Si-woo’s balls to his brain along a bundle of nerve fibers as if stabbing him.

    Si-woo’s entire body, which had become as sensitive as if he had reached a climax, contracted to the fullest extent and then shuddered as if in a tremor.

    Si-woo was struggling to accept the three different types of pleasure felt simultaneously in his penis, testicles, and anus.

    Si-woo was barely able to steady his trembling body due to the intense pleasure he was feeling for the first time.

    Si-woo felt his head going blank and his mind becoming hazy.

    Regardless of the older brother’s condition, the younger sisters were clinging to the sensitive inner flesh and genitals of his crotch with such persistence.

    Si-woo’s penis, reflecting the intense pleasure that Si-woo was feeling, swelled up again to the fullest extent inside Sun-joo aunt’s vaginal opening.

    “Haaahhhh!”

    Sun-joo aunt immediately groaned in response to the pressure exerted by Si-woo’s penis expanding and plugging her vaginal opening.

    She was not able to see exactly what was happening with her eyes covered.

    However, she seemed to be roughly guessing the situation through the younger sisters’ saliva flowing down her anus and testicles to the point where the genitals were joined, and through the state and reaction of Si-woo’s penis, which was expanding and writhing violently.

    Sun-joo aunt’s legs, freed from the younger sisters, wrapped around Si-woo’s waist once again.

    As Sun-joo aunt’s thighs wrapped around Si-woo’s pelvis and waist, her vaginal opening simultaneously squeezed Si-woo’s huge penis as well.

    Pleasure that felt like it was squeezing his penis spread throughout his entire body.

    Si-woo thinks that it is no longer possible to stay still and keep his mind focused.

    “Huuuuuuuuu….”

    After taking a slightly long breath to calm down his excitement a little, Si-woo put his right arm through the gap between Sun-joo aunt’s raised arm and head.

    Si-woo pushed his arm in deeply and positioned it so that his forearm supported the back of Sun-joo aunt’s neck, and he grabbed Sun-joo aunt’s shoulder with his hand and hugged her almost as if he was binding her.

    Si-woo pushed the other arm, which had been supporting the bed, behind her back and wrapped it around her as well.

    Si-woo made her stay fixed in his arms with his arms crossed around Sun-joo aunt’s neck and torso.

    Soon, Si-woo put strong force into the arms hugging Sun-joo aunt, and he began to move his waist.
