Pet Sister (3)
As Siwoo approached the door, Seo-yoon gulped down a dry swallow. Her heart was pounding so hard from the tension it felt like it might leap out of her mouth. She scrambled on all fours and dove behind the living room sofa.
Did he catch me? No, I can't let him...
The moment she barely managed to hide her body, the master bedroom door creaked open wide. Siwoo poked his head out and glanced around the living room. Chae-eun, who had been panting heavily on the bed, propped herself up on her elbows and asked,
"Siwoo, what's wrong all of a sudden? Is something up?"
"Nah, just thought I saw the door move a bit."
Siwoo replied nonchalantly as he squatted down in front of the door. He lightly ran his finger over the floor. A clear, sticky fluid clung to his index finger. He rubbed it between his thumb and forefinger, smirked, and stood up. He turned back into the room as if nothing had happened.
"It's nothing."
Seo-yoon, hidden behind the sofa, finally let out the breath she'd been holding. Her whole body was drenched in sweat. But more than the fear, the fact that Siwoo had discovered her 'trace' excited her even more. Whether by mistake or on purpose, Siwoo walked away without closing the door again. Knowing she could get caught any second, Seo-yoon cautiously crawled back toward the door crack. Transparent love juices dripped from between her crawling legs, leaving trails along her path.

Siwoo returned to the bed and stood in front of Chae-eun. Seeing his mom, he smirked.
"What's with you all of a sudden?"
Chae-eun pouted grumpily, pressing her legs together and rolling onto her side. Her face was full of sulkiness.
"Son. You've been playing around with Seo-yoon so much lately, aren't you neglecting your mom?"
Chae-eun grumbled with a pouty expression. It wasn't unreasonable for her to feel neglected. For the past few days, her daughter Seo-yoon had been sleeping in Siwoo's room every night, and even during the day, she stuck to him like a shadow. To Chae-eun, who was already completely tamed by Siwoo, it wasn't a pleasant sight.
Because she couldn't have sex!
No proper sex for days, not even a chance to relieve her urges. The most she got during Siwoo's brief bathroom breaks was sucking his cock, and it had been ages since he'd properly fucked her pussy. In fact, tonight she'd half-kidnapped him on his way back from the bathroom and dragged him to her room to pounce on him. Otherwise, who knows how many more lonely days she would've endured.
At her cute whining, Siwoo chuckled softly and lifted her chin.
"Mom, you don't like me getting so close with Seo-yoon sis, huh?"
"Of course I... don't hate it. I'm just feeling left out. Your cock is the best for me too, but it feels like my daughter's stealing it."
Chae-eun stuck out her lips again. Siwoo knelt on the bed and moved toward her head.
"Got it. I'll let you suck my cock, so forgive me just this once."
Chae-eun pretended to be reluctant as she lightly gripped Siwoo's cock. She stuck out her tongue and licked the glans and urethra like it was candy.
"Just this once? Mom wants to get fucked by your cock every day, but if you keep ignoring me, I hate it... I really hate it."
Chae-eun whined coquettishly as she took his cock deep into her mouth. Slurp, slurrrp— smack— Obscene sounds filled the room. Siwoo gently stroked her hair and continued,
"Don't worry. Soon I'll fuck sis right in front of you, and then pound both of you in the same bed."
At those words, Chae-eun paused mid-lick. She pulled her mouth off and looked up at Siwoo.
"Son, what did you just say?"
Chae-eun's pupils and voice trembled faintly. Seeing that, Siwoo made a strange face. He'd already told her in advance about fucking his sister and gotten her permission, but had she never even imagined doing it together in one room?
But Chae-eun's next words completely threw him off.
"The bed might be too small for all three of us, right? Should we buy a bigger one?"
Siwoo burst out laughing in disbelief.
"Pfft, the bed?"
"Yeah. This one's too cramped for three. Queen size won't cut it. King size? Or maybe get a custom-made one? It needs to be wide if Seo-yoon and I are gonna sandwich you on both sides."
Chae-eun's eyes were dead serious. Moral guilt or jealousy meant nothing to her anymore. All that mattered was how to more efficiently and comfortably share her son's cock with her daughter.
"Mom, you sure you're okay with that? You wanna see sis doing it with you?"
"Oh please, what power does she have? She can't live without you. I'll teach her properly. She's your pet too, just like me."
Chae-eun stroked Siwoo's thigh with a seductive smile.
"A bit different, though? Sis is pet sis, and you're bitch mom."
"Same difference. And."
Chae-eun pouted again. Then she lightly nipped his cock.
"Ow."
Siwoo winced and groaned. Chae-eun giggled mischievously and blew on it gently.
"That hurt? Mom's heart hurt more when you left her alone. And you wanna keep talking about Seo-yoon even now?"
Jealousy flickered in Chae-eun's eyes. At least in this moment, she wanted his full attention on her alone.
"Okay, okay. No more sis talk."
Siwoo grabbed Chae-eun's thigh and spread her legs wide.
"Shall we start again?"
Chae-eun arched her hips eagerly, ready to take him in. Beyond the door, Seo-yoon heard every word without missing a beat. Her face flushed beet red, and hot fluids gushed from between her legs again.
"Mom's... just like me..."
She said they were different, but to Seo-yoon, bitch mom and pet sis weren't all that different. That explained why Mom had been neglecting her lately. With her own master to attend to, how could she spare attention for the rest of the family?
Drool trickled from her mouth and dripped onto her nipples. All three of us... with Mom... Just imagining it melted her brain. Siwoo handling both her and Mom at once. Their moans mixing on the same bed. Seo-yoon rubbed her cheek against the floor, panting lowly. In the dark living room, her fingers rubbed her pussy again.
Meanwhile, Siwoo reached out and twisted Chae-eun's pink nipples. At the same time, he slammed his cock into her pussy.
Squelch—
"Hnnnghaaah♥"
Chae-eun cried out in ecstasy, gripping Siwoo's shoulders tight. Her pussy walls clenched hard around his cock. Siwoo savored the sensation, grinding his hips deeply.
"Mom, been a while? Feels tighter than usual."
"Hah, hah...♥ I've been holding back. You only cared for Seo-yoon and didn't come to me."
Chae-eun complained bitterly even as she pulled Siwoo close, wrapping her legs around his waist.
Squelch— squelch— squelch— squelch—
Siwoo thrust his hips up roughly. The wet slapping of flesh echoed rhythmically.
"Ohhhng! Ah! Siwoo, harder, harder...♥"
"You like this? Mom's turned full bitch now."
"Yes, Mom's your exclusive bitch... So fuck me harder, son♥"
Chae-eun's face melted away. Her eyelids drooped, pupils lost focus and rolled up. Sweat-soaked hair clung to her face, drool dripped from her outstretched tongue.
Love juices flowed from her pussy, squeezing the pounding cock tight. Siwoo grabbed her waist and flipped her over. Chae-eun got on all fours, ass high. Siwoo gripped her waist and thrust in from behind.
"Hnnngooooh♥"
Siwoo spanked her ass and pounded like a beast. Chae-eun clutched the sheets, moaning wildly. Juices streamed from her hole, soaking Siwoo's thighs.
"Ah, aaahng♥ Siwoo♥ I'm, I'm cumming again! Ohhhng♥"
She convulsed in yet another countless orgasm. Siwoo held back his load and flipped her onto her back. This time, Chae-eun mounted him.
"Son...♥ Stay still...♥ Mom'll do everything♥"
Chae-eun placed her hands on his chest and rocked her hips. Her breasts jiggled with each bounce. Siwoo watched from below, toying with her nipples.
"Ah, hah...♥ Feels good, Siwoo?"
Chae-eun ground her hips with a pleasure-drunk face. Each time his cock hit deep inside, her eyes rolled back as she gasped.
"Siwoo, I love you...♥ My son, superior stud...♥"
"Love you too, Mom. Can I cum now?"
"Yes, yes! Fill me up! Don't give it to Seo-yoon, all to me♥"
Chae-eun shook her hips with her last strength. She slammed her ass down, taking him as deep as possible. Her pussy clenched squeeeze, begging for cum. Instinctively, her walls pulsed and milked him from within. Slick pussy flesh chewed at his cock base.
Overwhelmed by the building climax, Siwoo grabbed her waist and thrust up hard. He pressed his cock tight against her womb entrance and unleashed hot semen.
Spurt— spuuurt— splurt— spurt—!
The throbbing pulses reached deep inside Chae-eun.
"Hoooaaaah♥"
Her body jerked wildly, ass twitching. Stiff nipples quivered, pussy and womb gulped greedily, squeezing every drop without spilling. Squeeeze—
"Hng♥ Hng♥ Hiiihhhnnng♥"
Chae-eun sprayed love juices as she collapsed forward, hugging Siwoo tight. Her belly swelled against his. After days without, her womb and brain overloaded with joy—she flailed her legs, kicking the blankets. Mind-shattering pleasure.
"Hiiiguuuh♥"
The long ejaculation finally ended, filling her womb to the brim. Even after, Chae-eun trembled in his arms. Her cum-stuffed womb quivered with aftershocks.
Chae-eun rubbed her cheek on his shoulder, sighing happily.
"Hah...♥ Hah...♥ My son really is the best♥"
Chin on his shoulder, Chae-eun peeked up. She glanced through the slightly open door crack and flashed a victor's smile.
