Ryu Se-hee Discovers the Pleasure of Her Rear
“Haa... Ah...!”
Ryu Se-hee regretted it.
If I knew it would be this embarrassing, I never should have agreed to it...!
Presenting her rear right in front of Tae-oh.
Showing him her most private, embarrassing place...!
“Relax. I'll slide it in slowly.”
“……Ngh…. Mmm…….”
She couldn't back out now...!
Tae-oh, having coated the beads in lube, pressed the first one against her entrance.
“Ah……. Haat……!”
If... if something like this goes inside me, I...!
“It's going in.”
“Ngh, mmm……… Hah!”
Squelch...!
Her flesh parted, and a firm, foreign sensation invaded her.
This... this bizarre feeling...!
Squish... slurp...!
“Mmm……. Haah...! Ngh...!”
“Don't tense up. It'll hurt if you do.”
“I... I know...!”
She slowly relaxed her muscles.
Doing this made her feel like she was completely surrendering her rear to Tae-oh.
It was just... just a single bead!
Squelch... pop!
“Hngh, ahh...!”
“Oh, look at that. It's going in. It's going... Ah!”
Pop...!
With a tight, closing sensation, the first bead slipped fully inside her.
It... it's inside... For real.
That huge bead is inside my body...!
It was strange.
Rather than hurting or feeling unpleasant... it was just a strange, full sensation.
But it didn't feel bad at all...
“Heh. I can see your entrance twitching from here.”
“Shut up...!”
Please don't say such embarrassing things, Tae-oh...!
As if presenting her rear and having beads inserted by a younger colleague from the next classroom wasn't humiliating enough...!
Showing Tae-oh her most shameful parts.
It was a blow to her pride so severe she shouldn't even be able to look him in the eye.
“Haah... Mmm...”
Yet, for some reason, Ryu Se-hee was starting to find it pleasurable.
I'm... getting excited.
Showing Tae-oh her shameful side...
...while having her rear stimulated like this...
It was an incredibly perverted act.
A shameful sexual act, so degrading she would never dare call herself a teacher if anyone found out.
Yet, doing this with a man for the first time in her life...
...brought a strange, budding ecstasy.
But she couldn't possibly ask Tae-oh for more.
“T... Take it out now, Tae-oh.”
Ryu Se-hee spoke reluctantly.
She didn't even look at him.
If their eyes met, she felt like her true feelings would be laid bare.
Actually, I'm a little curious.
What would it feel like if more went in...?
But if she begged for that from Tae-oh, the bad man who was blackmailing her...
...she felt like she would completely crumble.
“You put one in, so that's enough...!”
“True, we did say just one.”
“Right...!”
“Hmm.......”
Tae-oh stroked his chin, staring down at her rear.
She didn't know what he was doing staring at someone's backdoor like that, but she tried her best to endure it.
“Hmm... But how about we try just one more?”
“What?”
Ah.
She quickly hid the slight twitch of her lips before she could smile.
He... didn't see that, did he?
“Since we're already doing it, one more wouldn't hurt, right?”
“Kh...!”
No.
I have to say no. I have to tell him to stop...!
That we're done...!
But her mouth moved on its own.
“Just... just one more.”
“...Heh.”
She had inadvertently revealed her perverted side.
What on earth must Tae-oh think of me?
He probably already knew I was a pervert who loved my rear, but still...!
If he realizes that I'm actually enjoying this despite being blackmailed...
“Alright. Here comes the second one.”
“Ngh. O-Okay...!”
She relaxed her muscles and prepared herself.
Tae-oh is watching my rear.
Pressure was applied to the beads, and another one pushed its way inside.
Squeeeeze...!
Squish... pop...!
“Mmm... Haah! Ah... Mmm...!”
Why am I making these kinds of sounds...?!
She was too embarrassed to lift her head.
Her perverted desires, her vulgar moans.
If I show him this side of me as his senior colleague, I'll...
Squeeeeze... pop...!
“Ngh... Hah... Ha... Haah! Mmm...!”
“Heh... You must really love this.”
“Be... quiet...!”
“It's fine. Let it out. No one's going to judge you.”
“It's not about anyone else, it's you, Tae-oh...!”
“Me? Don't worry about me. I actually like your moans, they're cute.”
“Ngh...! What? H-Haang...! Mmm...!”
“See?”
“Ha... You're crazy... Mmm, hngh...! Mmm...! S-Slowly. Slow... Hngh!”
Squelch!
Another bead went in...
No. Wait.
Did... did two just go in at once?
The stimulation in her rear was on a different level. It was completely different from when just one had entered.
She could distinctly feel three beads inside her now.
Tae-oh... did you just sneak another one in?
“Relax a little more. Just a little more.”
“Mmm... Hnghhhh!!”
The initial promise of "just one more" had long been shattered.
Already, the fourth one...!
Yet, Ryu Se-hee kept her muscles relaxed.
She didn't reject the beads that Tae-oh was relentlessly pushing inside her.
Squelch... pop...!
“Mmm, hngh...! Haang...! Ngh...!”
Five.
“Haah...! Ah...! G-Gently...! Hngh...!”
Six.
Before she knew it, her insides were so packed with beads that it almost ached.
No. No more can fit...!
“Ah. I can't put any more in. That's the limit.”
“Ngh, h-haah...”
The moment Ryu Se-hee thought she had reached her limit, Tae-oh stopped with uncanny timing.
He felt the limit too.
It seemed he knew her body inside and out by now.
She gave her hips a slight wiggle.
“Hngh...!”
The beads, now too numerous to count, shifted deep inside her.
So many... beads...!
Unlike the heavy thrusts of Tae-oh's cock, this was a subtle, lighter pleasure, but...
...feeling it through her backdoor was strangely, incredibly satisfying.
While she wriggled her hips to savor the sensation, Tae-oh brought over his phone.
“Since we got so many in, how about a commemorative photo?”
“Haah...”
Just how many embarrassing photos of me are stored in that phone already?
She had already been photographed plenty. Videos had been taken, too.
Adding one more photo wouldn't change anything at this point.
Still, wanting to hide her face, she buried her head.
She simply raised her hips high, presenting them right before Tae-oh's eyes.
“……Take it.”
Click! Click!
To have such a shameful sight captured...
She had no idea what Tae-oh would think when looking at this.
Her authority as a grade chief, her dignity as his senior colleague—all of it had dragged through the mud.
And now, even this humiliating display was being recorded.
Yet, alongside the shame, Ryu Se-hee felt a strange sense of relief.
Even though she was being blackmailed, even though she was being forced into this...
...she felt a bizarre certainty that Tae-oh would never expose her secrets to anyone else.
Why on earth do I feel this way?
He's clearly a bad person who doesn't even deserve to be a teacher...
“Ah~ Photos are all done. Shall we take them out now?”
“…What? Take them out?”
At the unexpected words, her rear tensed up.
Tae-oh must have seen that, right? My entrance tightening up?
“Of course. Were you planning to keep them in? Want to wear them to work tomorrow?”
“N-No, of course not...!”
The remaining beads were dangling from her rear like a tail.
She absolutely couldn't go to work like this.
She had to take them out, just as Tae-oh said. But...
“Alright, I'll pull them out one by one.”
“Ngh...!?”
She felt the tug as Tae-oh pulled on the string.
W-Wait, if you pull them out now...
It already felt so strange when they went in...!
“It's similar to putting them in. Just relax, and I'll handle it. If you tense up, I can't pull them out.”
“Ngh... N-No...! Wait...!”
Tug...!
Tae-oh pulled the string taut.
Wait, what is this pleasure...?!
Because it was her own body, Ryu Se-hee could instantly predict it.
The moment they were pulled out...
...she would definitely feel a pleasure several times more intense than when they went in.
No...!
If you pull them out right now, I might actually lose my mind...!
She squirmed, trying to delay it.
“W-Wait! Just a moment. Can't we take them out in a bit?”
“No can do. We have to pull them out while the lube is still fresh, or it'll be harder later.”
“But if you pull them out right now, I...!”
“Alright. Here they come~”
“Ngh...!? W-Wait... Hnghhhh!!?”
Sluuurp...!!
Ah... Oh no!
They're coming out. They're coming out...!
They're forcing my backdoor open as they slide out...!
She tried to tilt her hips to stop it.
Tae-oh firmly gripped her cheek with one hand.
She couldn't even escape now.
Squelch...!!
“Ngh, hnghhhh...!! Hngh, ohhh...!!”
This is crazy. This is insane... insane...!
These beads... they were made to feel even better when pulled out...!
It was several times more humiliating than before.
To let Tae-oh watch the beads slip out of her rear like this...!
Squelch!! Pop...!!
“Oh, ohhh...!! Ahh...!!”
She couldn't even form proper words.
She tried to keep her moans sounding feminine, but she had absolutely no control over them.
It was too late to turn back.
She had already let him put so many in!
Once they're all out, then... then...!
Squish!! Pop!!
“Oh, ah...! Mmm! Ngh, Tae-oh, ah...! Tae-oh, I'm... I'm dying...!!”
“You're not going to die. Keep going.”
“Ohhhhh...!!”
I mean I'm dying of embarrassment!
Tae-oh pulled the string without a care.
Plop...!
“Ah-hyg...!”
Plop...!
“Ohh...!!”
Every time a bead popped out, a wave of intense pleasure washed over her.
No... if we keep going... I'll...!
“I'll pull the rest out all at once, okay?”
“Oh, hnghhh...!!”
No. No, Tae-oh!
Please, no more...!!
Sluuuuurp!!!
“Oh, ohhhhh...!!?”
The feeling of three beads sliding out at once...!
Ah... No. I'm going. I'm going to...!
Squirt! Squirt! Splat!
“Oh, ohhhhh...!! Hnghhhh...!!!”
“Whoa!?”
Oh my god... I came!
Along with the beads, all the strength drained from her body.
The love juice leaking from her pussy even splattered toward Tae-oh.
Squirrrrt...!!
“Oh, ohh... Mmm. Hngh, hnghhhh...!!”
Her hips shuddered uncontrollably, spraying her juices across the bed.
Such a perverted sight... something I would never, ever do...!
Her most vulnerable, vulgar state when experiencing true pleasure was laid bare before Tae-oh.
“Hah, haah... Haah... Hah...”
She lay on the bed, catching her breath.
Tae-oh plopped down beside her.
Is he... going to hold me?
“Wow~ Can you see this? The thing that just went inside your rear?”
“Hngh...!?”
Tae-oh waved the object in his hand.
The beads she had just hosted inside her...!
“Why are you suddenly showing me that...!”
“You should take a look too. This much of it went all the way inside you.”
“Hngh... ...Really?”
Tae-oh pointed to a spot high up on the string of beads.
That much went inside...?
Inside my... my rear...?
A shiver ran down her spine.
“D-Don't sniff it or anything! Seriously. I'll kill you if you do...!”
“It just came out of your body, so what's the big deal? It's not dirty at all.”
“S-Still...! It's embarrassing for me!”
“Come on. Between us?”
“Kh...”
What do you mean 'between us'...!
“And you washed your rear so thoroughly earlier. Didn't you wash it knowing this would happen?”
“………”
She didn't answer.
Answering would feel like admitting he was entirely right.
“Now that it's over... h-hurry up and throw it away!”
“Ah~ But I paid thirty thousand won for this. It's a bit of a waste to throw it away.”
“Throw it away anyway...! That... dirty thing...!”
“Nah. Throwing it away is a waste. And doing it just once feels a bit unsatisfying.”
Tae-oh looked at her while holding the beads.
With a gaze that seemed to pierce right through her inner thoughts.
“Se-hee.”
“………What.”
“Let's put them in one more time. Just once more.”
“Kh...! Tae-oh. Seriously...!”
He's asking because he already knows, right?
That I can't refuse.
There's no blackmail right now, but I'm still in no position to say no.
So I'm just accepting it because I have to.
“………”
...No, the truth is... I want him to do it again...
Casting aside her dignity as a teacher and her pride as his senior.
Forgetting everything, she just wanted to feel more of the pleasure Tae-oh gave her.
Slide.
“Haah……”
She presented her rear, still tingling from the stimulation, toward Tae-oh.
She tensed and relaxed, twitching her entrance.
“This is the last time... Just one more.”
Ryu Se-hee realized in this moment.
Even if she paid off her debt one day...
...she would never be able to go back to the Ryu Se-hee she used to be.
“……Class 2 Teacher.”
Holding her phone, Min Yu-ha's thumb trembled.
She had been staring at the draft message to the Class 2 teacher for over ten minutes.
Should I send it? Or not...?
Min Yu-ha's dilemma deepened.
