16. Interlocking
It had been a long time since she had returned to the Butt Wall Brothel.
Though she had resolved never to come back unless absolutely necessary, there was something she had to confirm. As long as she remained a disciple, she couldn't possibly ignore this issue...
Isabella repeated this in her mind several times as she gripped the doorknob of Room 1.
'It can't be. It must be my imagination. Countless people in the world must have moles on their buttocks.'
If it truly turned out to be Isabella's delusion alone,
she planned to politely apologize to "Room 1-nim" and somehow excuse herself to leave. Though it happened under the influence of alcohol, her body had already shared that kind of relationship with her Master.
Engaging in sexual relations with another woman under these circumstances was something Isabella's girlish sensibilities couldn't accept...
Though it seemed to be accepted as easily as the wind.
It was Isabella's personal resolve not to do anything shameful, let alone being in a lover-like relationship with her Master—their undefined, ambiguous relationship notwithstanding.
But—
The moment she entered the room, she saw buttocks hanging on the wall. She wasn't sure if "Long time no see" was the right greeting. Isabella's breath caught with a "Hup!"
"......"
There was a mole in the exact same spot on the right cheek.
Well, that's possible. Living in Bellua, there could be another woman with a mole in the exact same position.
Thinking this, Isabella reached out her hand.
Grope.
'...This texture.'
Though she had been toyed with by her Master's mischievous pranks countless times, she had never actively done anything herself—yet she recognized the feeling. Her Master's smooth skin. And that faintly perceptible body scent...
When she lowered her gaze slightly, just as expected, the pussy was slightly wet.
Could it be... anticipating something...?
At that moment, she became certain. This was undoubtedly her Master.
Then it all made sense. The reason why there had been absolutely no rumors about her own physique—perfect gossip material—despite it being a matter of principle.
Her Master had known from the very beginning.
The moment she realized this, strangely enough, Isabella's heart felt much more at ease. Guilt? Betrayal? No, rather than those, it was something like... a sense of exhilaration?
Before she knew it, a smile spread across her lips.
'This is Master's... true nature.'
Though her Master wouldn't realize it, Isabella's mental brakes had clearly shattered at this point. She calmly spoke up.
"...It's been a while. Room 1-nim."
"Yee...eah. Been busy?"
The voice was distorted.
But now that she recognized it, it sounded just like her Master's voice.
"I've had quite a lot of work. Some personal matters too..."
"Hmm."
"Ah, and thank you."
"For what?"
"Anyone else might have spread my secret as gossip. But Room 1-nim has kept it confidential until now. The fact that there are no rumors about me circulating in the Adventurer's Guild or taverns proves it."
"Mhm. That's just our brothel's principle. What happens in this room never leaks outside."
"......I see."
How many lies were mixed into Master's words?
How much of it was truth to begin with?
Had she been enjoying herself while teasing me all this time?
Isabella's gaze firmly settled on the buttocks fixed to the wall and the pussy. Truly obscene beyond measure.
A pussy quivering and twitching, waiting only to be penetrated.
As Isabella recalled, she was the fifth customer. That meant there had been four customers before her, meaning this pussy had taken four different cocks.
And still not satisfied...
'If Master desires it this much...'
Isabella slowly undid her belt. The metal buckle clinked as it hit the floor, and she removed her shoes one by one before pulling down her pants.
'Responding to that desire would be my duty as a disciple.'
Her cock stood fully erect as if blessed by divinity. The slight upward curve showed just how aroused Isabella was.
Hmm, perhaps "aroused" wasn't quite accurate—more like a complex mix of emotions?
Every time she recalled the faces of the men who came before her, her chest tightened strangely and she felt inexplicably angry...
Without understanding this uncomfortable feeling,
Isabella gripped her cock shaft and rubbed the glans against the pussy hole. The pussy was already soaked in love juice, making it slippery enough for easy penetration.
"......"
"......"
She was already subtly moving her hips as if enjoying it.
Could she possibly like it this much? To Isabella, this thing was nothing but a nuisance...
"...I'm putting it in."
Squelch—!
"Ah, ah, aah—!"
Gripping the trembling buttocks tightly, Isabella pressed her pelvis flush against them. With her cock buried to the hilt, she spoke while savoring the sensation of penetration.
"...Master?"
And in that moment,
"Ugh!"
The pussy tightly clenched around the cock, refusing to let go.
The vaginal pressure was incredible. Though no answer came, that was enough. How startled must she have been to react like this?
Of course... understanding without words and getting no answer at all were different matters.
Imagining her Master's silent figure beyond the wall, Isabella rubbed her pelvis against the buttocks. This bold action was unlike her usual self.
She probably didn't even realize what she was doing herself. Her actions were outpacing her thoughts due to dopamine overload.
"Aren't you... going to answer? Will you keep your mouth shut like this?"
"W-what are you talking about? Why would you look for your Master in a place like this?"
Truly, a cliché excuse.
"You don't know...? Then I'll have to make you understand."
Isabella began moving her hips.
Squelch, squelsh! Thrust, thrust!
She buried her cock to the hilt, then pulled back until just the glans caught on the pussy lips... then thrust back in to the root...
Repeating this motion.
"Hhh... hhh..."
"Hhuup..."
Was she covering her mouth?
If so, there was even less reason to hold back.
Slap! Slap! Slap—!
Until now, she had always been the one being played with. Those days of being foolishly teased and forced to show shameful expressions. She hadn't disliked it, but...
Knowing the truth now made her inexplicably angry.
Isabella resolved to properly punish this perverted Master who couldn't help herself. Using this very "cock" that she loved so obsessively.
"...Does it feel good?"
"Hhh, hhuup—!"
Isabella gripped Noah's pelvis tightly, observing her reactions.
Which angle made her clench tighter. Whether her buttocks twitched. If her waist trembled.
"Hmm, here perhaps?"
"...Haak!"
Thrust, thrust, thrust—!
She began tormenting the sensitive spot intensively.
And at some point, raw moans began coming from beyond the wall.
"Do you like cocks that much?"
"Haak, hak... heek, heek..."
When Isabella asked again, Noah only breathed heavily without answering.
"If you don't answer, I'll stop thrusting?"
"......"
The vigorous pistoning came to an abrupt halt.
Isabella wanted to cum too, but if she could torment her Master, what wouldn't she do?
Her cock, swollen with the need to ejaculate, hung precariously over the pussy, teasingly rubbing just enough to frustrate,
when a pitiful answer finally came from beyond the wall.
"...Don't know, I don't know... haa, please..."
"Why don't you know? Just today alone, you had four other men besides me. Did it feel that good? Even after... doing those things with me last night. I thought maybe you went out for some air because you were embarrassed to face your disciple, but to think you'd do such things with men in a place like this..."
As she spoke, anger welled up again,
Thrust!
She plunged her cock deep enough to reach the cervix.
"Ugeek—!"
"Huu... So I was the only one taking this seriously."
Isabella felt wronged.
She had come to correct her own misunderstanding and return, valuing her relationship with her Master. Yet the person she called Master had been enjoying herself with other men just one day later.
This elf mage,
this pitiable Master,
was clearly a certified pervert.
"Answer me. Did it feel good getting fucked by those bastards!"
"Oo, ook, oooooook..."
Thrust, thrust, thrust!
Piston strokes filled with resentment.
The sound of flesh slapping against flesh. Pelvises colliding. The sticky, squelching noise of joined parts.
Squelch, squelch—
Truthfully, Isabella's thrusting technique was terribly clumsy.
Given that her sexual experience could be counted on one hand, this was only natural.
But it was enough. Isabella's cock was truly first-class.
Ideal length, ideal thickness.
One could say it was an ideal cock molded by the gods. Not excessively large, but perfectly filling the pussy. The glans protruded at just the right angle to scrape against every fold of the vaginal walls.
Being relentlessly pounded by such a cock...
Noah beyond the wall couldn't maintain her sanity. To the point where she couldn't even spare the thought to block her senses, drooling profusely,
she finally had to answer in desperation.
"...Hek, heek... I-I didn't like it!"
"What was that?"
"Y-yours! Only your cock felt good...!"
An absurd confession.
Isabella paused her thrusting momentarily.
But come to think of it, this was infuriating too? Following that impulse, Isabella gripped Noah's pelvis hard enough to leave nail marks.
"...Ah, that hurts!"
"Master."
"Uh, yes?"
So now she's not even denying it anymore.
Should this be praised? Isabella pondered briefly.
No, praise was premature.
Scolding wasn't enough—what place was there for praise?
"...That sounds like you were comparing me to those men?"
"Haa, haa... No, it's not like that..."
Noah tried to make excuses, but Isabella had no intention of listening further.
"Fine. Then I'll let you compare more clearly. Before coming in here... I checked that I'm the last customer, right?"
"......"
"For Master's sake, I think I could keep thrusting for hours. I'll hold back from cumming, so please compare thoroughly."
"N-no, holding back ejaculation is bad for your hea— aak!"
Thrust! Thrust! Thrust! Slap, slap, slap—!
