After leaving the clubroom, the place we headed to was the men's restroom in the old school building. We moved into one of the stalls, and I sat Grayfia down on the toilet seat. I made her lift her long skirt up to her thighs, exposing the underwear that held the vibrator buried inside her cunt in place. Looking down at her from above, I listened as the low hum of the vibrator churned inside her, echoing faintly in the cramped space.
"Now then."
I lowered my pants and underwear, thrusting the pent-up cock that had been denied release straight toward Grayfia. Originally, I should've been finishing inside Rias' and Asia's hands by now — giving them a generous amount of "milk" for their black tea. But after being interrupted, the shaft stood swollen with anger, countless veins rising violently across its length.
I knew Grayfia might stop me, but desire is desire — it wasn't something I intended to fight.
"Start by calming my cock down."
"…Yes."
Unusually obedient, Grayfia reached out with both hands and brought her face close to the tip.
Then she kissed my urethral opening.
It lasted maybe five seconds — far too short for my liking.
"You think that's acceptable?"
The moment she pulled back, my words forced her to press her lips to it again.
She slowly kissed the cock, tasting me. After glancing up to read my expression, she gently took the swollen head into her mouth, enclosing just the tip. Inside, her tongue flickered softly, teasing the urethra directly. The married woman's earnest, intimate kiss made my cock twitch hard, spilling threads of precum.
Grayfia sucked the liquid noisily before returning to lick the opening again.
She repeated it three times — apparently deciding that was enough — and lifted her face, eyes steady on mine.
"…Good enough."
"Thank you."
"So, what did you need to talk about?"
"That matter is—"
She paused briefly, inhaled once, then continued.
"I ask that you do not lay your hands on Lady Rias or her servants."
I didn't need to ask to know. But it played out exactly as expected.
"…And your reason?"
As I spoke, Grayfia stroked my shaft with her right hand while gently massaging my balls with her left.
"…Because they are precious to me. My younger sister-in-law and her household."
While speaking, she tapped the head lightly with the tip of her tongue, brushing left and right.
Grayfia Lucifugus was not merely a maid of House Gremory. She was the wife of Sirzechs, Rias' elder brother — making Rias her sister-in-law.
Why she continued to use her maiden name and serve the Gremory family as a maid — I didn't know; I was still relatively new as a devil. But in this situation, it was clear she couldn't treat this as just employment.
She was offering up her own body just to protect Rias.
"If your sister is that important, then why not devote your entire life to me? That would protect her completely."
"I have other loved ones as well. I cannot entrust my entire life to you, Riser-sama."
I wondered what it felt like to hold such selective devotion while servicing my cock.
Part of me wanted to ask — but decided this conversation had run long enough.
All this "precious," "family," sentimental nonsense disgusted me.
Eventually, I would dirty all of it.
"…Fine. I won't touch Rias or her servants."
At least not yet.
"Thank you."
"It's fine. …Ah, right. About your payment — it won't be starting today."
Grayfia, who had been licking along the underside, halted nervously.
"It won't be the next seven days starting now. It'll be the seven days I choose. When I call for it, you'll be my woman for an entire week. You will serve only me, and you will put genuine affection into it. After that week ends, you can go back to being the emotionless maid you pretend to be."
"…When does it begin?"
"Undecided. Until then, you don't need to be kind to me."
Grayfia's silver eyes searched me for intent — then emptied.
Emotion withdrew, leaving only the mask of a professional maid.
"…Understood."
"Then that's all?"
"Yes."
"Good. Before we return, make me feel good."
"…Yes."
Without changing her expression, Grayfia extended her tongue, licking me from balls to tip. The cock trembled at the stimulation, and she began stroking the shaft, taking the head into her mouth. Her movements were more assertive than usual — likely her attempt to end this quickly.
Even devils can't fully suppress emotion; no matter how hard you hide it, cracks always appear.
And that crack — I only needed to tear it wide open.
If I pried it apart and slid into the empty space inside her heart, I could claim her completely, drowning her in pleasure until she belonged only to me.
That goal had just moved one step closer.
Swirling her tongue around the head like candy, she increased her stroking pace. My pleasure rose, the shaft swelling, throbbing sharply, dripping more fluid as I enjoyed the service of a superior female.
Time to finish.
I didn't restrain the rising pleasure — instead, I bent my knees slightly.
Grayfia, with her mouth around my cock, looked up in confusion as my waist lowered — then her eyes widened at what followed.
I pressed down on the vibrator bulging under her underwear.
"…nh—!"
The vibrating rod slammed against her cervix. The semen stored inside her womb must have been shaking too. Grayfia flinched at the shock but maintained her service.
When she continued pretending nothing was happening, I pushed the vibrator deeper.
Maintaining a cold façade was clearly difficult — her face sometimes twisted in pain as she sucked me.
Hurting women was fun.
"Come on."
Bzzzzzz — the hum intensified.
The tip struck deep inside her, buzzing loudly.
Finding it amusing, I reached beneath her underwear and grabbed the vibrator directly, stirring her insides.
"…ngh—…"
I rotated it against her deepest point. The sound she let slip around my cock made my grin widen. Feeling the tremble in her body, I thrust my hips forward.
"Mmmph—gh…!"
My cock filled her mouth completely. Slick warmth wrapped around me. I grabbed the back of her head, preventing retreat, and shoved myself to the base.
Tears welled at the corners of her eyes.
She desperately drew in air through her nose buried in my pubic hair.
Using a woman like an object, forcing her to struggle — the domination was intoxicating.
I climaxed immediately.
Splurt—! Spurrrt—!
I ejaculated deep into her throat.
The moment her expression twisted in shock, I shoved the vibrator hard against her cervix. Her eyes unfocused instantly.
"Mggh—! Nnkg—! Guh—…!"
Choking down my semen in agony — she looked adorable.
I poured it mercilessly into her like I was emptying myself into a toilet bowl, forcing her throat to swallow every drop.
Grayfia convulsed violently.
Nearly fainting, she still gulped desperately and managed to drink it all.
Satisfied, I withdrew and yanked the vibrator out of her cunt.
Gurp—splsh—glorp.
The semen stored in her womb spilled from between her spread thighs, dripping messily like she was relieving herself.
Grayfia, exhausted and trembling, looked as if she might collapse.
Sirzechs would surely love to see his wife looking like this.
I let her wallow for a while, rubbing my cock against her cheek until she slowly regained awareness. Like waking from a dream, she focused — then directed a shaken gaze up at me.
"Clean it."
Showing her the shaft still streaked with semen, I watched as she obediently began licking it clean. Her lips adhered to the cloudy white fluid smeared across the red-black cock, slurping it up. She used her tongue to scoop the remaining semen from the groove around the head.
It didn't take long before the cock shone with spit, the throbbing flesh gleaming.
"Good work."
When I patted her head gently, she turned away with an expression mixing humiliation and shame.
One day, I would twist that expression into pure ecstasy.
After our "discussion" and my release, I fixed my clothes.
I sent Grayfia back to the clubroom looking tidy, while I myself left the old building.
I had already abandoned today's plan to visit the wedding venue with Rias. Instead, I ordered Grayfia to convince the sulking Rias in my place.
"Prepare a situation where I and Rias — plus everyone involved — can freely decide whether the engagement happens. If you can convince me in a way that leads to a result favorable to you, I won't complain."
She looked like she wanted to say something — but accepted.
Whatever happens will depend entirely on Grayfia's actions.
If she wants to keep Rias away from me — she'll have to beg with her body again.
Grayfia saw me off as I left the old school building.
I had another objective for coming to the school today.
To avoid suspicion against a blonde man in a red suit wandering around, I expanded my brainwashing field to cover the entire campus.
Slipping easily into the school grounds, I passed right beside male students heading out through the entrance.
Once inside, enjoying a wave of nostalgia about my student days, I checked the classrooms one by one.
Then I found them — a trio of eighteen-year-old female students chatting after class.
Pretty faces, good bodies.
Once confirmed, I stepped into the classroom.
"Ah— n-no— someone—!"
I raped them. One by one, after removing their brainwashing temporarily.
In the same classroom where they normally attended lessons.
Frustrated that I couldn't soil Rias and the others, I bred these girls instead until satisfied — stuffing their human wombs full of devil semen.
Afterward, I left them on the floor, treating it like dumping trash.
"It was a masked rapist," is what I implanted as their memory.
Sexual urges satisfied.
"Uniforms and gym clothes: secured."
My spoils: their school uniforms and their gym uniforms.
All three sets were placed into my Item Box.
While stepping on the bellies of the three naked girls lying in a pool of semen, watching it ooze from their gaping cunts, I mulled over what to do next.
I'd modify the uniforms later — or maybe keep them small and make them wear them tight over their adult bodies for that mismatch appeal.
Imagining Grayfia cosplaying in them made my cock stir with excitement again.
Satisfied, I left the classroom.
