Jinwoo started massaging by mounting Gyuri's back after laying her face down.
Aunty Gyuri was wearing a white, loose-fit round t-shirt with a floral skirt that emphasized volume down to her knees.
Jinwoo's cock was fully erect.
He sneakily looked around.
Aunt Haeju was still lying face down on the sofa in the same position she received her massage, asleep, while his mom had gone into the kitchen, starting to do the dishes with clattering sounds.
From where Jinwoo was, he couldn't see his mom in the kitchen.
Jinwoo pressed his massive cock against the crack of Aunty Gyuri's ass, rubbing her shoulders and back with his palms as if wiping them down.
Aunty Gyuri tensed up under Jinwoo's touch.
It felt like Aunty Gyuri's plump ass clenched and then relaxed, trying to grip Jinwoo's pressed cock with her ass crack.
"Are you okay?"
Jinwoo's question was cautious, contrary to his bold actions.
"Uh huh... feels good."
Aunty Gyuri, distracted by her surroundings, let Jinwoo do as he pleased.
Wondering when Minji and Sua might come out of the room...
No clue when Sohee might come down from the second floor...
Right next to them on the sofa, Haeju, a close friend of Aunty Gyuri, he also had no idea when she might wake up.
When it was Aunty Gyuri's turn, mom saw Jinwoo's erection and touch while massaging Aunt Haeju, but she vacated the spot and went into the kitchen.
The situation seemed a bit chaotic to Aunty Gyuri.
Jinwoo's hands moved from Aunty Gyuri's waist to her ass.
As if it was only natural that he owned that ass of Aunty Gyuri...
Jinwoo gripped Aunty Gyuri's ass roughly with both hands.
"Ah~~"
A heavy sigh escaped Aunty Gyuri.
Since Daeho had shockingly slapped Aunty Gyuri's ass...
After Jinwoo had casually slapped her ass and texted as if nothing happened...
Jinwoo knew it would come to this with Aunty Gyuri.
This was something Jinwoo had been secretly hoping for and anticipating.
* * *
Jinwoo felt slightly concerned about his mom giving up her spot.
What could mom be feeling right now?
He pulled out his smartphone and opened the camera app.
He framed and took a photo ensuring it captured his erect cock positioned between Aunty Gyuri's ass cheeks and his hand clutching her butt.
Click
Aunty Gyuri, looking a bit flustered, glanced around before laying back down to continue enjoying the massage.
Jinwoo sent the photo he took to his mom via a smartphone message.
Soon after, a notification sound came from the kitchen, and the sound of dishes being washed stopped.
The '1' on Jinwoo's message screen disappeared.
Mom would now be aware of what was going on between Aunty Gyuri and Jinwoo.
The kitchen remained silent for a while.
Jinwoo felt a thrill in showing his mom his lewd act with Aunty Gyuri.
He felt a slight shiver of excitement.
Jinwoo resumed caressing Aunty Gyuri.
He slid his hand under her skirt, caressing the bare skin of her thighs from behind and then moved his hand up the inner thigh towards her groin.
His hand momentarily touched the intimate center of Aunty Gyuri.
Aunty Gyuri flinched.
With her arms pulled forward and face buried down, Aunty Gyuri slightly spread her legs to make it easier for Jinwoo's hand to move.
In the quiet living room, the sound of Jinwoo's palm rubbing against Aunty Gyuri's thigh could be heard.
Then, a text notification rang on Jinwoo's smartphone.
It was from his mom.
He picked up the phone to check the message.
It simply read:
"Contraception!!"
Contraception...
Jinwoo smirked.
Aunty Gyuri turned slightly, looking puzzled.
Jinwoo felt excited, as if he had his mom's approval to be with her friend, but also found it somewhat amusing.
No matter that Jinwoo was a pervert who masturbated with his sister and younger sister's panties and played tricks on his own mom at night, he had never thought of having sex with his mom's friend in the living room of a house full of family during the day.
Jinwoo found it endearing how his mom cared for him in this way.
Then, the sound of running water from the sink resumed in the kitchen.
Jinwoo had a playful idea.
He told a bewildered Aunty Gyuri to wait a moment and headed towards the kitchen, fully erect.
* * *
Mom was doing the dishes in front of the sink, wearing her usual favorite gray pleated skirt.
Jinwoo approached her from behind, grabbing her waist just above her ass.
Mom was startled.
"Mom, aren't you tired? Should I help you?"
Jinwoo asked in a soft voice.
"No, no... I'm fine, I can finish this quickly by myself," Mom stammered, flustered.
This was the first proper conversation they had since the morning's text.
Jinwoo pressed his erect, massive cock against Mom's ass.
Mom's ass twitched for a moment.
She glanced around the living room and then bowed her head.
Her face was as red as it had been the previous night.
"Did you think I was having sex with Gyuri?"
Jinwoo whispered quietly into Mom's ear.
He had deliberately used Aunty Gyuri's name to provoke Mom.
Mom listened quietly, swallowing her saliva.
"Don't worry, I want my first time to be with you," Jinwoo said.
Mom's body seemed to tremble slightly in response to Jinwoo's words.
Jinwoo slowly rolled up Mom's skirt from the ass upwards.
Mom checked the living room again and then looked forward, letting Jinwoo do as he wished.
Now, Mom's gray pleated skirt was rolled up enough that Jinwoo's hand held it, exposing her shapely legs and panties.
"But really, Mom, you're so stubborn. It'd be better if you wore just your underwear around the house..."
Jinwoo whispered provocatively right into Mom's ear.
"Since you're being so stubborn, as a punishment, from now on, you can't wear panties at home," Jinwoo said as he pulled down Mom's panties.
Mom was startled as her panties slid down to her ankles.
"From today on, no wearing panties at home! Got it?"
Jinwoo tapped Mom's ass with his palm and signaled her to lift her feet to remove the panties completely.
Mom glanced at Jinwoo, sighed, and alternately lifted her feet to slip out of her panties.
"Good Mom~"
Jinwoo stood up and stroked Mom's ass, still turned away and bowing her head.
Mom's panties were already wet with arousal.
* * *
Jinwoo returned to the living room where Aunty Gyuri was lying face down, carrying his mom's panties.
After confirming that Aunt Haeju was still asleep, he casually tossed the panties next to Aunty Gyuri's face.
Aunty Gyuri picked up the panties and inspected them.
Only then did she seem to understand the full situation, and her tense expression began to relax into something more suggestive.
Jinwoo laid Aunty Gyuri down properly and moved beside her, slipping his hand under her skirt.
The crotch area of her panties was already soaking wet.
He brushed the panties aside and touched her with his middle finger, stirring it around to coat it with her fluids before gently pushing it inside her.
As Jinwoo's middle finger slid in completely, Aunty Gyuri's body stiffened as if electrified, her limbs trembling.
Jinwoo started to curl his finger, gently scraping the sensitive flesh inside her.
Her breathing grew heavy.
Each time Jinwoo curled and uncurled his finger, a squelching noise came from Aunty Gyuri's pussy.
Squelch, squelch, squelch
Aunty Gyuri, her face flushed, was biting her lip, seemingly holding back her moans.
Jinwoo thought to himself that his mom might also be hearing these sounds after receiving the text message, and it seemed to excite him excessively.
The idea of having sex in the living room in broad daylight, something Jinwoo had never considered, was something his mom had imagined.
Knowing this made him feel bolder.
The word 'Contraception!!' he received via text felt like mom had given permission for all the lewd acts happening inside the house.
Using his thumb, Jinwoo began to stimulate Aunty Gyuri's clitoris.
At the same time, with his other hand, he pulled out his fully erect cock and pushed it towards Aunty Gyuri's face.
"Gyuri, suck it!" Jinwoo said, seemingly forgetting to use formal language with her.
Aunty Gyuri, without hesitation, took his massive cock into her mouth.
Slurp—gag—
Now, the sounds from Aunty Gyuri's pussy and her mouth filled the living room.
Jinwoo felt the sensation of Aunty Gyuri's moist and warm mouth wrapping tightly around his cock.
He pushed her head down onto the floor to hold it in place and shoved his massive cock down her throat.
"Gag—gak—haaack"
Aunty Gyuri was greatly startled by the sudden intrusion of Jinwoo's hard and massive item in her throat.
With a serious expression and wide-open eyes, she coughed as if vomiting while Jinwoo's cock was still in her throat.
"Guk—guk—guk!"
Each cough sent intense stimulation through Jinwoo's cock.
Blood rushed to her face, turning it completely red, and veins popped out on her forehead.
Aunty Gyuri's eyes were bloodshot, and tears mixed with mascara started running down her face, making black tear streaks.
She trembled violently as if she had reached a climax.
Jinwoo moved his cock back and forth in Aunty Gyuri's throat a few times before pulling it out of her mouth.
Haack—cough—gasp—haaa—haaack
Aunty Gyuri finally caught her breath.
Watching her, Jinwoo violently shook his cock and finally sprayed a full load of semen on her face.
Jinwoo took out his smartphone and snapped a photo of Aunty Gyuri's face splattered with semen, then sent it to his mom.
It seemed Aunty Gyuri was pleased to be participating in this play of excitement, as she gasped for breath with glazed eyes but was smiling with the corners of her lips turned up.
The notification number next to the photo sent to his mom disappeared.
Jinwoo used his mom's panties to wipe the semen off Aunty Gyuri's face.
