Chapter 430 (Mom)(Karaoke)

"Here, Mom! Use these to wipe up! We need to get ready to go home!"
Si-woo spoke as he tossed a thick pack of wet wipes he’d grabbed from a vending machine onto his mother’s lap.
Perhaps it was because of the conversation they’d just had in their 1:1 chat room as mother and son, or perhaps it was Si-woo’s indifferent attitude as he pointed out the hair peeking out...
Mom kept her flushed face lowered as she used the wet wipes Si-woo had thrown to clean her soiled body.
First was her face and the area around her mouth, then the inside of her groin covered by the bikini bottoms, and finally the rest of her skin where Si-woo’s urine had touched.
Si-woo used the mop he’d brought to wipe up the moisture that had splashed onto the floor while he was pouring his urine over Mom’s face and into her mouth earlier.
"I guess we shouldn't do this kind of thing indoors anymore. Cleaning up is such a pain! Right?"
"If we’re going to do it, we should do it completely outdoors, or only in the shower or bathroom at home."
As he mopped the floor, Si-woo spoke to Mom as if analyzing the problems and improvements for the watersports play they had just finished.
"Huh?... Y-yeah... I... I think you're right..."
Mom replied as if in agreement, wiping the moisture from around her breasts, which were covered by the red fabric.
After roughly wiping the floor, Si-woo leaned the mop against the wall and approached Mom, who was still cleaning the skin around her breasts.
As Si-woo drew near, Mom’s hands, which had been busy wiping her body, flinched and came to a halt.
Approaching her, Si-woo pulled several wet wipes from the pack resting on her lap.
He placed the wipes on the skin of her chest peeking out from the swimsuit and began to rub gently, as if tickling her, wiping away the filth clinging to her skin.
It seemed Mom had completely lost any will or intent to resist Si-woo’s touch now that he had come to dominate her.
She simply focused on positioning her breasts so that Si-woo’s hands could reach them easily.
Si-woo’s hand, which had been stroking her chest, slid down toward the boundary between Mom’s white breast flesh and the swimsuit covering it.
His hand instantly slipped into the gap between the skin of her breast and the fabric.
As the cold wet wipe touched her sensitively peaked nipples, Mom instinctively hunched her shoulders and shrank back, looking momentarily flustered.
Si-woo began to stroke the bare skin of her breasts beneath the swimsuit fabric, centering his movements around her nipples.
"Haahhh..."
Mom let out a long moan at Si-woo’s stimulation using the wet wipes.
"As soon as we get home, you should shower before dinner, Mom."
Si-woo spoke while scratching at Mom’s nipples through the fabric of the swimsuit.
"Y-yes... As soon as... as soon as we get back... I’ll have to... shower..."
Mom answered Si-woo with a stutter, looking flustered by the peculiar sensation against her nipples.
It was almost as if she were merely repeating the instructions he had given her...
"I’d love to shower with you as soon as we get home, but Se-hee and Se-young are there right now, so that’ll be a bit difficult, won't it?"
Si-woo spoke while rolling Mom’s nipple between his fingers.
"Mmm... Yeah... Since Se-young is there too... Haah..."
Mom replied with a sweet, melting moan that matched the rhythm of Si-woo’s fingers rolling her nipple.
"Didn't we say we’d live exactly as we used to at home while Se-young is awake during the day?"
Si-woo asked her again, framing it as a question to confirm one of the conditions Mom had originally set for approving the play.
Due to his dominant tone in the chat and the creampie he had given her, the other two conditions had essentially been rendered moot.
In such a situation, Si-woo was asking the question as if to confirm the one remaining condition.
"Yes... Th-that’s right... Because... we promised that...!"
Mom spoke to Si-woo with a firm expression and tone, showing her determination to somehow maintain their everyday family relations, which was one of the conditions she had set for her approval.
"Then as soon as I get home, I’ll just head up to the second floor bathroom, wash up quickly, and come back down! That works, right?"
Contrary to expectations that he might be stubborn, Si-woo spoke as if expressing his intent to uphold the first condition Mom had set.
"Y-you will?"
At Si-woo’s words, Mom’s firmly set expression relaxed awkwardly.
"Rules are rules~ Oh! And... you’re still making Se-hee and Se-young take their contraceptive pills, right? Did you say there were four weeks left?"
Si-woo then asked to confirm the second condition regarding the family’s contraception.
"Huh?... Y-yeah... Since... it hasn't been long since they started taking them..."
Having already declared herself a slave in the group chat and even having been creampied by Si-woo, Mom trailed off and answered shyly, as if she felt she had no right to speak on the matter.
"I should stop by a pharmacy on the way home and buy a lot of condoms. Considering I’ll be using them on two people for four weeks, the ones we have at home won't be nearly enough."
Si-woo spoke as if Mom’s second condition was still entirely valid for everyone except her, who had just made her slave declaration and received a creampie today.
"Okay..."
Mom gave a short, fading reply, her head bowed as if she had committed a crime.
"What about you, Mom? Should you go to a hospital?"
Si-woo asked, sounding concerned about Mom’s pregnancy and contraceptive status.
"F-for now, I think I’ll have to wait and see... It’s not like it happens right away just because we did it..."
Mom answered Si-woo, clearly conscious of the possibility of pregnancy.
Although she had accepted her son ejaculating inside her, she still seemed to harbor anxiety and discomfort regarding getting pregnant.
After meticulously wiping one breast and nipple beneath the fabric of Mom’s dress top, Si-woo withdrew his hand.
He pulled a fresh wet wipe from the pack on Mom’s lap.
"Right... Let's do that for now. You’d know more about that than I would, Mom~"
Si-woo spoke as he slipped his hand under the swimsuit on her other breast.
"...And what else was there? The things I promised you?"
Si-woo asked Mom, who couldn't recall for a moment.
It seemed Si-woo was going through the conditions Mom had set for participating in the master-slave play one by one, trying to adjust them to the changed situation.
"The... text messages..."
Mom answered in a tense voice, her body twitching in response to the cold sensation of the wet wipe on her other breast.
"Ah! Right, the 1:1 text messages! We were supposed to keep talking as mother and son in the chat window... right?"
Si-woo spoke as if it were a shame, catching Mom’s firmly protruding nipple between his fingers.
He even addressed her by name, as if speaking down to an inferior...
"......"
This time, Mom couldn't answer, merely watching Si-woo’s reaction.
"I’ll have to be careful not to get excited while talking to you via text from now on, Mom~"
Si-woo spoke to Mom as if casually brushing off his recent mistake.
"Mmm... From now on... Haah..."
Mom answered, straightening her back and gasping for breath.
"I’ll make sure to set things back to the way they were, so don't worry...!"
Si-woo spoke as if making a vow, firmly grasping Mom’s chest as it pushed forward when she straightened her back.
"Mmm... Haah... Hng..."
Instead of an answer, a nasal moan escaped Mom’s lips at Si-woo’s words.
* * *
The vibrator had stopped at some point, its battery drained.
In the room where the vibrator’s hum had vanished, the sound of Mom’s heavy breathing and the muffled accompaniment of the karaoke machine leaking through the half-open door filled the space.
"Is that enough? It looks like it’s almost dinner time... Se-hee and Se-young will be waiting. If you don't have anything else to say, shall we head home?"
Si-woo withdrew his hand from Mom’s swimsuit, where he had been fondling her breast, and spoke as he helped her stand up.
"Uh... B-but Si-woo... Am I really going home like this?"
Mom asked Si-woo, looking troubled as she belatedly covered her swimsuit-clad chest and groin with her arms.
She had worn the bikini Si-woo bought as a last resort, thinking it was better than being naked, but now that it was time to actually step outside, she couldn't bring herself to do it.
"Why? You were walking around just fine earlier with nothing but a T-shirt on and no underwear."
Si-woo spoke mockingly to Mom, who was hesitating over the swimsuit despite having gone out earlier wearing only a T-shirt without underwear or bottoms.
"The T-shirt at least... covers my whole body, so as long as I’m careful, people won't look at me strangely... But... this is..."
Mom trailed off as she countered Si-woo’s words.
Slap!
As if offended by her words, Si-woo suddenly slapped Mom’s buttocks from below.
"Hyah!"
As Si-woo’s hand struck her buttocks hard again, Mom moaned, shrinking back in surprise from her awkward standing posture.
Si-woo reached out and grabbed Mom’s swimsuit top as if he were about to strip it off her.
"You fucking bitch! I keep putting up with you and you start acting like a piece of shit again?! You want me to just strip that swimsuit off you right now?! You want to walk all the way home butt-naked?!"
Si-woo raised his voice and cursed, shouting at Mom to intimidate her.
