Siwoo approached Aunty Gyuri, who was tied up naked.
Her voluptuous and full breasts were shaking with every twist of her body.
Siwoo’s thing got harder and harder as he watched Aunty Gyuri’s body, unable to tell if she was holding back her urge to pee or enduring the passion.
Sure enough, just like Cheoljin said, it seemed Aunty Gyuri enjoyed this kind of degradation.
The humiliating position Aunty Gyuri was in, tied up as she was, couldn’t have been achieved without her cooperation.
Even for a man, it wouldn’t have been easy for someone like Cheoljin, who was just a mid-level academy student, to completely subdue a mature woman like Aunty Gyuri with strength alone.
But even so, was it really acceptable for Siwoo to treat Aunty Gyuri like a slave and have sex with her as if he were raping her?
Aunty Gyuri, lying there tightly bound with ropes, looked like she had been denied her existence as a human being.
Her anal opening, slick with vaginal fluids and twitching, was exposed right in front of Siwoo’s eyes.
What in the world could be so important about that worthless piece of paper with no legal force that made Cheoljin treat his mother this way?
Siwoo hadn’t always avoided coercive or forceful actions with other women in his past relationships.
But those were always acts of perversion carried out to test the other person’s will…
Or deviant acts performed in a state of mutual understanding, sure that the other wouldn’t refuse.
-Except maybe for what he did to sleeping Seyoung-
What Siwoo was about to do now was to treat Aunty Gyuri like a real slave and rape her.
No matter what kind of person Aunty Gyuri was, it was real rape to deliberately skip the process of asking for her will or true feelings.
Reality seemed to have escaped out the open front door.
Siwoo’s thing throbbed huge, as if it was going to penetrate Aunty Gyuri’s pussy at any moment.
**
Siwoo grabbed the large dildo stuck in Aunty Gyuri’s pussy.
The dildo was held in place between her legs with a net like a stocking.
Siwoo moved the dildo up and down after slightly pulling the net to the side.
The dildo, which had been tightly gripped by her pussy flesh, moved heavily in Siwoo’s hand.
-Creak! Creak! Creak!
「Uuh… Uuuh… Haah!」
Aunty Gyuri’s moans leaked out cautiously, suppressed so as not to be heard outside the front door.
「Che… Cheoljin, mom really thinks she’s at her limit now. Uuh… Uuh… O… Okay, can you let me go to the bathroom first?」
Aunty Gyuri’s voice sounded like she was about to cry.
Siwoo forcefully shoved the dildo deep inside and then pulled it out.
「Haaaah!」
Aunty Gyuri’s love juices, heavily coating the end of the massive endoscopic dildo, melted down.
Meanwhile, the rotor on her clitoris kept vibrating non-stop.
Siwoo brought the dildo to Aunty Gyuri’s mouth.
When the large dildo that had just been inside her body, warm with her fluids, touched her lips, Aunty Gyuri flinched and recoiled.
The love juices spread like a coating on Aunty Gyuri’s lips from the dildo.
「Please~ I’ve been doing everything as told. Haah… Can’t you forgive me now?~ What happened yesterday was because dad made me do it. Huuuh…」
Aunty Gyuri mumbled, trying to make excuses with her wet lips smacking.
Aunty Gyuri, moving her body, begged her son again, almost as if praying.
Siwoo’s sadistic instincts surged uncontrollably as he watched Aunty Gyuri, who was pleading for forgiveness for reasons he didn’t fully understand.
Siwoo swung the large dildo in the air and struck Aunty Gyuri’s cheek.
-Smack!
The soft material of the dildo lightly stuck to Aunty Gyuri’s cheek.
「Haaah!」
Although the hit wasn’t very strong, it was enough to fluster Aunty Gyuri.
-Smack!
Siwoo struck the other cheek.
「Uuuh…」
Aunty Gyuri let out a groan, feeling humiliation and shame.
The kind and gentle Aunty Gyuri he had known since childhood.
He knew she treated him with much more care than Cheoljin’s other friends because she was his mom’s best friend.
And now, Siwoo was doing the crazy act of hitting that Aunty Gyuri’s cheek with a dildo soaked in her love juices.
A strange exhilaration spread throughout Siwoo’s body from deep inside his chest.
It was a different kind of thrill and excitement from when he slapped her butt or shoved his penis down her throat before.
The figure in front of Siwoo’s eyes was no longer his friend’s mom and his mom’s best friend, Aunty Gyuri.
She was just a female slave named Gyuri, bound by a slave contract to someone.
**
Siwoo inserted the dildo back into Aunty Gyuri’s crack.
-Squelch squelch squelch!
This time, from the start, he thrust the dildo deep enough to stretch Aunty Gyuri’s vaginal walls.
「Haaah haaah haaang」
Aunty Gyuri gasped painfully, losing her breath.
Siwoo immediately pulled out the deeply inserted dildo from Aunty Gyuri’s cave.
Her sticky love juices clung thickly to the dildo again.
Siwoo licked the juices on the dildo.
He decided to do another crazy act.
He spread Aunty Gyuri’s love juices evenly over his penis.
Then, grabbing the base of his dick with one hand, he swung it towards Aunty Gyuri’s butt.
-Smash!
The dull sound of flesh hitting flesh echoed in Cheoljin’s living room.
-Smash! Smash!
Siwoo slapped Aunty Gyuri’s cheeks with his wet stick several more times.
「Uuuh… Uuh…」
In the moment of humiliation, Aunty Gyuri’s body shook violently.
Did she think her son was still hitting her cheeks with a big dildo?
Siwoo felt himself getting more uncontrollably excited, imagining Aunty Gyuri’s feelings.
**
Siwoo untied the ropes wrapped around Aunty Gyuri’s legs.
Her legs, which had been bent, stretched out slowly as if they were numb.
Siwoo unlocked the handcuffs binding Aunty Gyuri’s hands with the key he got from Cheoljin.
Then, he removed the headphones that were blocking external sounds.
Now, Aunty Gyuri, with some freedom to move and feel, raised her hands to remove the blindfold.
-Slap!
Siwoo smacked the back of Aunty Gyuri’s hand with his palm.
Aunty Gyuri recoiled again.
Understanding Siwoo’s rules, she lowered her hands.
Siwoo grabbed the red collar around Aunty Gyuri’s neck and pulled hard.
Aunty Gyuri, who had been leaning against the sofa backrest, fell forward slightly, landing on her hands and knees on the living room floor.
Siwoo tugged the leash silently, as if training a dog.
「Uuh… Uuh…」
Aunty Gyuri groaned, seeming exhausted from the humiliation, but she quickly adapted and started crawling on all fours.
Siwoo led Aunty Gyuri to the bathroom, feeling like he was walking a dog.
-An act he wished he could make his mother do someday-
Upon reaching the bathroom, Aunty Gyuri immediately tried to sit on the toilet.
-Slap!
Aunty Gyuri felt a burning pain as Siwoo unexpectedly struck her butt.
「Haaah! Uuuh…」
Unable to bear the pain, Aunty Gyuri collapsed to the floor in a convulsion.
Siwoo gently caressed Aunty Gyuri’s butt, soothing her.
Aunty Gyuri’s trembling gradually subsided under Siwoo’s touch.
Siwoo got Aunty Gyuri back on all fours.
With the bathroom door open, he led her near the bathtub.
He placed one of her legs on the bathtub edge.
Aunty Gyuri, now on one knee and both hands on the floor, with one leg hooked over the bathtub edge, looked like a dog about to pee.
Siwoo patted Aunty Gyuri’s butt.
Aunty Gyuri seemed to understand exactly what Siwoo wanted her to do.
The urge to pee at its limit.
Holding it in was her last act of dignity as a mother.
Aunty Gyuri’s body shook.
-Fssshhhh
Finally, clear and transparent yellow liquid poured out from Aunty Gyuri’s urethra.
Unable to hold back her urge to pee, Aunty Gyuri began to release it all, letting go of her last shred of dignity as a mother.
