Chapter 23: Before You Wash, Why Don’t You Let Your Cunt Wash Master’s Dick?
Ever since Rosenberg had begun walking on two legs as if nothing were strange at all, she hadn’t laid a finger on me. That didn’t mean she had stopped tormenting me, though.
“Aria, let me wash you.”
“D-don’t come in…!”
“I’m just doing my duty as your master and washing my female pet clean.”
“If you had any conscience at all, you’d at least cover that thing dangling between your legs before you said that!”
Whenever I went into the bathroom to wash, she would fling the door open and stroll in naked. Her purpose was always the same: to wash me herself.
Of course, I refused every time.
Even when I went to the toilet to take care of business, she made it impossible to have a moment’s peace.
“Oh? Our Aria’s going to take a piss?”
“Shut your damn mouth.”
“Want me to carry you if it’s hard to walk?”
“I said shut up!”
If she wasn’t going to lay a hand on me, then she could at least keep that filthy mouth still—but no, she was as shameless as ever, constantly flicking my nerves raw with her endless teasing.
With that kind of thing happening over and over, my mental exhaustion had piled up so badly I felt like I might collapse again any second.
“Aria, aren’t you going to wash?”
“This place isn’t the only bathroom in the world. I’m going somewhere else.”
“Why?”
“Why? Because of you, idiot.”
Even during dinner she had hovered over me, and after dinner, nothing changed. The way she watched for the instant I’d step into the bathroom was no different from a cheetah stalking prey.
“But you have to wash here.”
“And why is that?”
“Because I, your master, decided it. Naturally, my female pet should obey.”
I got to my feet, crossed to the closed door, and gripped the handle. I just wanted to wash in peace for once.
“If you open that door, things are going to get pretty interesting.”
Whenever she said things would get interesting, it usually meant I was about to be fucked senseless.
It seemed she had no intention of letting me leave this room alone, not when it would mean breaking the promise not to touch my body.
“So there are things out there I’m not supposed to see?”
“A cunt is between Aria’s legs, isn’t it?”
I frowned at the vulgar joke and turned back—then my eyes flew wide open.
She was sitting on the bed with her legs spread openly, rubbing the towering shaft standing stiff between them.

“W-what are you doing…?”
“I haven’t given this bitch any load lately, so it stays hard even when I’m not touching it.”
With a sly smile, she began stroking the length faster and faster. Anyone looking at her would have called it masturbation. And yet her cock remained rigid, showing none of the subtle reactions one would expect from pleasure.
“No response, even this far. I guess my dick needs a dedicated cunt to satisfy it.”
Maybe it was only my imagination, but that cock looked even more obscene than before, far bigger than I remembered.
It had been a full week since she’d last pinned me down.
Considering how much she always spilled whenever she climaxed, even after cumming every day, there had to be an enormous amount built up inside her.
“How about it, Aria? Before you wash, why don’t you let your cunt wash Master’s dick?”
“...Shut up.”
Leaving her to keep stroking herself, I went into the bathroom attached to the room.
Afraid she might burst in again, I locked the door tight, leaned against it, and let out a long breath. Then my legs went weak and I slid down to the floor with a dull thud.
“Haaah…”
I exhaled again and buried my head between my knees.
“Why am I getting wet?”
The instant I saw that cock standing there, my lower belly began to pound. No—deeper than that, I could feel a trembling vibration from somewhere far below.
It was unmistakably the sensation of my womb sinking low and shuddering.
I had gone a week without my body once entering a state of heat, so I’d overlooked it—the fact that this body always became aroused so easily in front of certain things.
“It looked huge… and so hard…”
Just imagining what would happen if that thing went inside me sent a chill down my spine, and my whole body quivered.
To check exactly what state I was in, I dragged one finger lightly over my cunt.
“Hnh…♡”
A clear strand stretched between my finger and my slit, then snapped with a sticky little tug.
As if that had been the signal, my entrance spasmed on its own and slick flowed out in a steady trickle.
“This really does make me a bitch…”
Come to think of it, for the past week, every time I saw her cock, my eyes had naturally drifted toward it and locked on.
Even when she barged in while I was washing, my gaze had still gone there in the middle of my startled shouting.
This body had been craving her cock more and more as time went on.
“Haaahh♥ H-hihihik♥ Dick…♡ So goooood♥”
All at once, my own voice echoed in my head—panting as I was fucked by that disgusting cock.
I clapped both hands over my ears and shook my head, but the sound only came back clearer, longer, like an echo.
“P-please… s-stop…♡ I’m not a bitch…!”
As my body was being made to want her cock, I had accepted the physical pull. But that didn’t mean I accepted being a bitch.
“I can’t… do this…♡”
I kept denying it out loud again and again, until—
My right hand had somehow slipped down between my thighs and was rubbing my cunt.
Thrrrk—!! Thrrrk—!!
“Hahhh…♥ Why is it… so wet…♡”
Once I started pressing and rubbing with a slow, heavy pressure, slick burst out of me like a broken dam.
Not only that—my cunt was so hot it felt like it might burn my fingers.
It was the first time this body had ever been this desperate.
I couldn’t believe it had come to this simply because her cock hadn’t been inside me for a week.
“Hahh…♡”
The moment I unconsciously tried to push my finger deeper, a tingling shot through my nipples. My finger, which had been heading inward, brushed against the edge of my areola and slowly pressed down.
“Huhyaaah♥”
As though it had been waiting for that, both nipples popped up, round and stiff.
They trembled too, proof of just how aroused I was.
Thrrrk—!! Thrk-thrk-thrk-thrk—!!
“Hahhuhh♥ Hihiik♥ This isn’t… n-not good…♡”
I couldn’t even stop myself from rubbing between my clit and my slit.
If Rosenberg saw me like this, she’d fuck me right then and there. But with the door locked tight behind me, there was no way she could know I was masturbating.
Crreeeak—!!
“Hwahaaah♥”
Like a woman under some spell, I shoved my finger deep and pressed against the wall above me. My fingertip found the sensitive spot exactly, and my hips jerked up in one sharp spasm.
Along with it, slick splattered everywhere.
“I’m already… this wet…♡”
I pulled my finger out in resistance to the tightly clenching walls, then spread the entrance open and swirled it in small circles.
“Hihyaaaan♥ So hot…♡ That’s why it’s so hot…♡ Smells lewd…♡ Hihiit…♡”
The faster I moved my finger, the hotter and rougher my breathing became, and the thick scent rising from between my thighs only drove me further insane.
By now, the bathroom floor was soaked with the slick I’d sprayed everywhere. The air inside the room had long since been filled with the smell of my arousal.
“Hurry…♡ and finish…♡ Then I can wash…♡”
Afraid she’d suspect something before I was done, I moved my fingers even faster. Enjoying the wet, squelching sounds, I used my other hand to squeeze my breast hard enough that it felt ready to burst.

“Hyaaahhh♥ J-just a little more…♡”
I was frantically working my sensitive spots when—
“My, my? I wondered why it got so quiet. So you were masturbating in secret, behind your master’s back?”
Rosenberg’s voice came through, and I froze cold with my nerves on edge.
“H-how did you get in here…? I locked the door.”
I lifted my head in a stiff, jerky motion and found Rosenberg staring down at me, her cock dangling right in front of my face.
“You really thought there was only one bathroom door here?”
With that, she pointed behind herself.
It had definitely been a wall of white tile. And yet the wall had opened up into the shape of a door.
“If you can masturbate, I guess your body must be feeling better.”
“N-no, that’s not—”
It was over now. The life I’d had a week ago was about to return, and the daily routine of swallowing that cock—right in front of me—with my mouth and cunt would start all over again.
“Get up, Aria.”
But contrary to what I expected, she slipped her hands under my armpits and hauled me to my feet.
The moment my fingers left my cunt, slick pattered onto the floor. The sound was so obscene that I could only cover myself hurriedly with my hand.
“What are you being shy for? You’ve pissed yourself in front of me more than once.”
“Are you… going to fuck me now?”
“I’ll let it slide today.”
Let it slide? Rosenberg?
That wasn’t something I’d expect to hear from her mouth, not when she had only one thing on her mind—fucking me into becoming a bitch.
“Instead, we’re going to wash together.”
“O-okay…”
Washing together was a far better option than being fucked until my cunt split open.
Warm water flowed from the shower hose, slowly soaking both our bodies.
Just as she’d said, she stood behind me and did nothing obscene at all.
Is she really not planning to fuck me? Judging by the way she acts, it sure doesn’t seem impossible.
She had kept her promise all week, so I might have been able to trust her—if not for the fact that she’d caught me masturbating and left me even more on guard.
“How long were you holding out if you masturbated enough to fill the bathroom with the smell of cunt juice?”
“Th-that’s… d-don’t ask…♡”
“You can answer that much, can’t you? Or am I wrong?”
Even though I dodged the question, Rosenberg only smiled lazily and slowly covered my back in a layer of soap foam.
Then it happened.
Thud—!!
“Hihihit♥”
Her stiffened cock pushed up between my ass cheeks and pressed hard against my cunt.
Thrrrk—!!
“Hihyaaah♥”
A moment later, it bounced and dragged sharply, so keenly across my cunt that it made me gasp.
“Oh, sorry. I can’t exactly do anything about a cock that’s already hard, you know.”
“Hnngh…♡ Haaah…♡”
It was obvious this wasn’t deliberate contact as she leaned close to wash my back.
The problem was that the brief, solid touch of her cock had made my cunt react before I could stop it.
Slick began to pour out again without pause, soaking my thighs until water and arousal were impossible to tell apart.
“I’ll wash your breasts too, Aria.”
“W-what? I can do that mysel—♡ Hahuhhh♥”
Before I could refuse her, she grabbed my breasts so firmly it felt like they might burst.
Just when I thought this had to be intentional, some kind of obscene touch meant to make me heat up, she only lathered them with soap and then let go cleanly.
Was she really only planning to wash my breasts?
I couldn’t be sure.
“Hnng…♡”
Her cock pressed against my tailbone as she washed me. That, too, was only natural contact for bathing my body.
The shaft shifted minutely, rubbing between my ass cheeks with a subtle friction.
It was all so ambiguous—those touches, those movements—that I couldn’t decide which way to read them.
