Chapter 424 (Mom)

Was it now impossible to expect the same reactions or the woman she used to be from Mom, who seemed to have just completely surrendered to Si-woo?
Along with a flicker of guilt for creampieing her, her failure to give a proper answer stirred a strange sense of disappointment and resentment within him.
It felt just like that morning after she had taken Se-young and left the house, when she hadn't responded to his texts...
* * *
Even long after the accompaniment from the karaoke machine had faded...
The sounds of a group of female students chattering in the hallway drifted in a few times.
Fortunately, it seemed people rarely passed by the secluded room where Si-woo and Mom were.
Si-woo remained standing, draped over Mom’s back with his penis still inserted.
The only sounds in the room were the low hum of the vibrator, which was still running, and the heavy breathing of the two.
His bladder had been full for a while now, but Si-woo felt too lazy to move just to go to the bathroom.
He picked up his smartphone and first stopped the vibration of the device that had been relentlessly stimulating his penis.
"Hauuuu..."
Only then did Mom let out a deep breath, her body finally going limp.
It seemed she hadn't been able to relax even after Si-woo reached his climax because of the constant vibration.
Si-woo idly kneaded her breasts, moving his inserted penis back and forth slightly to create friction.
His semi-flaccid shaft scraped against the semen filling Mom’s vagina.
The semen flowed down the pillar planted inside her cave.
The streaks of his semen, still holding the heat of his body, trickled down to meet the skin of Mom’s thighs.
Lowering the hand that had been massaging her breasts, Si-woo wiped the semen from her thigh.
He then brought his hand, coated in the fluid, to her lips.
Mom flinched for a moment as his semen-slicked fingers touched her mouth, but she soon relaxed and accepted his touch.
Si-woo spread the semen around her parted, gasping lips in a circular motion.
Perhaps the sensation was unfamiliar, as Mom shrank back slightly, her lips trembling.
However, she did not close her mouth or turn her head away in rejection of his lewd act.
For a moment, Si-woo wondered if he could make her deal with his urine, just as he had done with Aunt Seon-ju or Su-a.
He moved the hand that had been tracing her lips back to her back and began to write letters.
[I], [Need to], [Pee]
Si-woo wrote the words on her back as if informing her of his situation.
Mom’s breathing hitched slightly from the sensation of his finger tracing the letters on her skin, but she didn't offer a specific answer or reaction.
[Can I], [Do it], [In Mom?]
Si-woo asked for her opinion, expressing his immediate urge by thrusting his softening penis deeper into her.
"...Si... Si-woo... that... ah... in... inside... the... the floor..."
Mom opened her mouth, hurriedly twisting her waist and looking back over her shoulder with a troubled expression.
Did she think he was going to urinate directly into her pussy hole while still inserted?
Seeing her so flustered caused Si-woo’s penis, which had been wilting inside her, to suddenly throb with strength.
It wasn't a full erection capable of intercourse again, but it swelled enough for Mom to feel it clearly inside her vaginal opening.
Si-woo’s original plan was to pull out, make her kneel, and have her open her mouth so he could spray his urine inside.
But seeing her panic, he decided to modify the plan slightly.
Shhhhhhh!
Without any further warning or signal, Si-woo began to urinate while his penis was still buried deep inside her.
His hot urine sprayed deep into Mom’s cave.
An alien sensation of liquid filled the space between the slick walls of her vagina and the skin of his penis.
Immediately after starting, Si-woo flexed his sphincter to cut off the flow.
A tingling sensation vibrated through his penis.
"Si... Si-woo, this is...! No... haah...! Really..."
As she felt the hot liquid—not semen—entering her pussy hole, Mom spoke as if in a state of total panic, her body twisting restlessly.
Slap!
Si-woo struck her buttock with his palm to stop her movement.
"Hng!"
Mom’s pussy hole tightened, and she froze with a sharp moan.
Shhh! Shhhhhhh!
Si-woo urinated into her hole a couple more times, stopping the flow each time by tensing his sphincter.
The urine overflowing from her hole mixed with the slick white fluid and trickled down her thighs.
"Haah... if you do this... on the floor... ha-eu... really...!"
Mom spoke with a mix of irritation and distress, pressing her thighs together to prevent the stream from hitting the tiled floor.
But soon, overcome by a surge of humiliation and helplessness, she fell silent and hung her head.
"Ha-uuuuu... seriously..."
Sobbing breaths escaped her lips.
Si-woo stood there for a moment, watching her reaction, before writing on her back again.
[I'm going to do it in your mouth, will you drink it?]
Si-woo gave her a proposal that left her no choice.
At his suggestion, which was no different from a command, Mom nodded her head vigorously up and down while still propped on all fours.
Sliiiide!
Si-woo’s penis slid out of Mom’s pussy hole, accompanied by a mess of fluids.
"Hng...!"
A handful of yellow liquid mixed with semen spilled onto Mom’s thighs.
Mom rubbed her legs together, trying to manage the mess he had made.
"Kneel and turn around! Look me straight in the eye!"
Si-woo commanded in a firm voice.
"Haah..."
With a heavy sigh, Mom turned around and knelt on the floor.
Her face, now turned toward him, was positioned right below Si-woo’s semi-erect shaft.
Si-woo gripped his penis and aimed the tip at her face.
Mom tilted her head back slightly with her mouth open, closing her throat and breathing through her nose.
Her shoulders heaved as she took ragged breaths.
Pshhhhhhh!
A powerful stream erupted from the tip of Si-woo’s semi-erect penis.
The fierce jet of urine sprayed from his penis, splashing droplets everywhere as it poured into Mom’s wide-open mouth.
"Haup! Gulp, gulp, hmmm... gulp, gulp."
Mom immediately swallowed the urine filling her mouth.
While receiving and swallowing the urine, her eyes looked straight up into Si-woo’s, just as he had ordered.
Looking into her eyes, Si-woo felt a thrilling sensation spread down his spine.
Even while urinating, his penis throbbed and twitched with strength.
Chwaaaaa!
The stream of urine Si-woo was spraying suddenly jerked upward as his erection grew, missing her mouth and marking her face instead.
"Hng!"
Startled by the stream hitting her face, Mom’s body jolted, and she closed her eyes while keeping her mouth open.
Si-woo quickly steadied her head and shoved his shaft into her mouth.
As soon as he inserted it, Mom’s lips clung cooperatively to his shaft, as if trying to prevent any urine from spilling onto the floor.
Chuuuuu!
The relentless stream of Si-woo’s urine continued to erupt inside her mouth.
"Gulp, gulp... ugh! Ugh! Gulp."
Her cheeks puffed out as she struggled to swallow the urine filling her mouth.
Streaks of urine she couldn't handle leaked from the corners of her lips.
"Look at me!"
Si-woo commanded Mom, who had her eyes squeezed shut against the spray on her face.
Mom soon opened her wet eyes and looked up at him.
Her blinking eyes seemed to convey a multitude of emotions and thoughts to Si-woo.
He picked up his smartphone and set the vibrator to level 1.
Bzzzzzzzz!
Mom’s eyes widened slightly at the sound of the vibration starting again, then returned to their original size as she continued to gaze at him.
Having endured Si-woo’s relentless torture at the highest setting, did the level 1 vibration now feel like nothing more than a sweet spice of pleasure to her?
Si-woo released his grip on her head and stroked her damp hair as if tidying it.
As the stream of urine began to taper off, Mom’s tongue, creating a slick yet textured sensation, pressed against the underside of his shaft.
While maintaining eye contact, she began to lick his shaft clean, stroking it softly as if teasing him.
Si-woo was inwardly shocked by her voluntary act of sucking his penis without even being told.
