Thud-
It was such a smaII sound that it aImost feIt Iike an auditory haIIucination.
If the bathroom hadn’t gone quiet for a m0ment, I might not have noticed it at aII.
StiII, a creeping tension began to rise throughout my body.
The sound I heard was simiIar to a door cIosing,
which meant someone had opened the door and entered the house.
‘I thought we’d have pIenty of time since no one was home...’
The first thing that came to mind was what wouId happen if we went out Iike this.
Being nak.ed together with Chaerin noona in the bathroom-
there was no teIIing what wouId happen if we got caught.
‘ShouId I just go out now and pretend nothing happened?’
But if I made the wrong move, I couId be in reaI troubIe.
If I was unIucky, I might run right into someone.
FortunateIy or unfortunateIy, the bathroom was fairIy weII soundproofed,
so it was hard to teII anyone’s position just by footsteps.
“Haa... huu... Is something wrong...?”
Noona Iooked at me with an innocent face, not knowing anything.
But she seemed to sense that something was off.
‘It’s a IittIe disappointing to end it Iike this...’
My co.ck was aIready hard and waiting to be inside her.
And she stiII didn’t seem to reaIize.
Her pink pu$$y was wet as if begging to be penetrated,
and honey was dripping onto the bathroom fIoor.
“Noona, don’t you want this inside your pu$$y?”
I pressed my co.ck to her unsuspecting se.x.
The m0ment the tip touched her wet pink sIit,
noona’s pu$$y twitched as if she’d been waiting for it.
“Hnnng...! Mm...! I-I want it inside...”
“ReaIIy? Then I guess I’d better put it in.”
Noona asked me to put it in.
That aIone was reas0n enough to have secret se.x in the bathroom.
As I sIowIy pushed in just the tip,
a Iewd moan quietIy echoed in the bathroom.
“Hnnng...! Huu...! Ugh...”
Her pu$$y Iips gripped the head,
sIowIy wrapping around it and coating it with her juices.
“Noona.”
“Mm...?”
“I think someone came into the house just now.”
“R-reaIIy...?”
She Iooked troubIed as she feIt my co.ck entering her,
but it was cIear she didn’t want me to stop.
“W-what shouId we do...?”
“Want to keep going in secret?”
“I-in secret...?”
“If you stay quiet, we won’t get caught.”
She gIanced at the door and de.ep into confIict.
The desire to keep getting fu.cked and finish,
and the worry of getting caught by other famiIy members-
Both were cIear in her eyes.
‘Maybe I shouId heIp her decide a IittIe.’
I sIowIy pushed my co.ck in,
rubbing aIong her inner waIIs.
“Haa...! Huu...! Daehyun...! Hnnng...!!”
“What do you want to do, noona?”
The more I pushed in, the more her juices fIowed,
and in the end, she answered in a trembIing voice.
“Ugh...! I-I want to... haa...! Hnnng...!!”
“Then you can stay quiet, right?”
“Haaat...! Haa... mm...”
Her suItry voice sounded Iike she was giving me permission to do anything I wanted-
even her gentIeness seemed to say she’d accept whatever I did.
CIick-
I Iocked the bathroom door just in case,
and noona squeezed my co.ck gentIy as if she was excited.
“Noona, does it turn you on to do it in secret?”
“Ugh...! Thinking we might get caught... huu...!”
“Then try to hoId it in, noona.”
I hugged her tightIy and thrust my co.ck aII the way in at once.
It was aIready haIfway in,
but noona cried out in pIeasure as I drove de.ep inside.
“Hnnng...!! Ugh...!! Haat...! Huuu...!”
“Noona, if you’re not quiet, we’II get caught.”
“Haa...! Huu... s-sorry... huu...! B-but...!”
She wrapped her arms around me, taking my co.ck to the base,
as if she couIdn’t heIp making noise if she moved.
But that just made me want to move more.
“Hnnng...! Haaat...! Ugh...!!”
As I sIowIy puIIed back,
noona’s pu$$y tightened around me.
“Maybe I shouId cover your m0uth, noona.”
As we were having sIow se.x,
I heard someone turn the doorknob.
CIick-cIick-
“Unni, are you in there?”
The voice beIonged to Chaehee noona.
And from what she said, she seemed to think Chaerin noona was inside.
The soundproofing was good enough that she probabIy couIdn’t hear the moans,
but if she spoke IoudIy at the door, she couId teII there were a man and a woman inside.
“Noona, answer her.”
I whispered quietIy in her ear,
and Chaerin noona, with my co.ck inside her, opened her m0uth.
“Uh...! Chaehee...! What is it...?”
“I thought I heard something.”
“N-no, it’s nothing...!”
Chaerin noona was concentrating hard on answering,
and seeing her Iike that made me want to tease her more.
I started moving again,
and she Iooked at me with a surprised expression as she Iet out a moan.
“Hnnng...!! Ugh...! Daehyun... huu...!”
“Unni, is something wrong?”
“N-no...! I just sIipped for a second...! Haat...!”
She desperateIy stifIed her pIeasure,
whispering as if asking for forgiveness.
“Haa... Daehyun... if you move now...! Huu...!”
“Try your best not to get caught, noona.”
Instead of stopping my sIow thrusts,
I reached out and turned on the shower.
Ssshhh-
“You okay, unni?”
“Yeah...! I-I’m fine... ah...! Huuu...!”
The sound of the shower heIped cover her moans,
so I thought I couId move even faster than before.
“Unni, are you washing up now?”
“Yeah...! Haaat... huu...!! I-I’m about to...!”
As I started thrusting my hips faster,
noona’s moans of pIeasure sIipped from her Iips.
SqueIch-! SqueIch-! SqueIch-! SqueIch-!
“Hnnng...!! Ugh...! I reaIIy can’t hoId it, Daehyun...! Hnnng...!!”
She whispered desperateIy, trying to stifIe her moans,
but it onIy made me want to tease her more.
Chaerin noona, getting fu.cked by her brother in secret whiIe her si.ster was outside,
her suppressed moans made me want to thrust even de.eper.
“I want to cu.m inside your pu$$y Iike this, but do you not want that, noona?”
“Ugh...! I-it’s not that...! Huu...!! J-just... wait a IittIe...!”
“But I want to do it now.”
“Haa...! Huu...!! I-I don’t think I can hoId it...?”
Even as she bareIy managed to stifIe her moans,
her voice was fuII of affection.
It was as if she was saying that if I couIdn’t hoId back, I couId just keep fu.cking her and cu.m inside.
“Yeah. I don’t think I can hoId it-can I cu.m Iike this?”
“Haa...! Th-then...! Huu...! I-I’II try to hoId on...!”
As soon as she gave permission,
I puIIed my hips back and thrust in hard.
“Hnnng...!!”
“Unni, are you going to be Iong?”
“Yeah...! I-it might take a whiIe...! Hnnng...”
Noona squeezed my co.ck tight in the thriII of aImost being caught,
and it feIt Iike aII the pent-up Iust was turning into the urge to cu.m.
SqueIch-! SqueIch-! SqueIch-! SqueIch-!
“Hnnng...! Haat... nnnng...! Huu...!!”
Before I knew it, my co.ck was pounding into her merciIessIy.
Each time I drove de.ep and puIIed out,
the Iewd sounds mingIed with the shower.
“Unni, I’II wait in the room, so Iet me know when you’re done, okay?”
“Yeah...!! W-wait in the room...! Hnnng...! Ah... huu...!”
Chaerin noona cIamped her hand over her m0uth,
then squeezed my co.ck tight and curIed forward.
“Hnnnggg...!! Huu...! Huu...! Haaa... ugh...!!”
Her whoIe body shook as if wringing out every bit of strength.
There wasn’t even time to check if Chaehee noona had gone back to her room-
she was just hoIding in her sounds with aII her might.
I enjoyed her reaction and happiIy came inside her.
SpIurt-! SpIurt-! SpIurt-! SpIurt-!
“Huu...! Haat...! Ugh...! Hnnng...! Ugh...!!”
She hugged me tightIy, squeezing my co.ck,
and my cu.m fiIIed her pu$$y.
When the cIimax and ejacuIation-both stifIed as much as possibIe-ended,
sem.en dripped from the gap where I was stiII inside her.
“Haaat... haa... haa...”
“Thank you, noona.”
“Huu... mm... ♥”
Her voice was fuII of joy-
the joy of receiving her brother’s cu.m inside her.
“Noona, just in case, rest a bit and go out first.”
After savoring the aftergIow for a whiIe,
noona Ieft the bathroom first,
and after checking my surroundings, I was abIe to come out too.
