After dinner, we took a bath as usual. And once I put Puck to sleep, we began our usual night routine together as my wives headed into the wardrobe room to get changed, while I entered the bedroom first.
As I wait for them, I transform the bedroom into something else. The massive, familiar bed is gone, stored away in my dimensional inventory. In its place, eight sets of metal cuffs temporarily fasten into the floor. And just beyond them stand eight milking machines — smooth crystal pumps, transparent tubes, and reservoirs — the devices I built myself with [Blacksmithing].
Then...
KNOCK! KNOCK!
"Come in."
The door swings open, and my wives step in one after another. Each one is wearing a new creation of my [Tailoring] skill, which is a cow-pattern ensemble of microbikinis with open-cup bras and crotchless panties that emphasize their fertile forms, cow-ear headbands, jingling cowbell collars, elbow-length gloves, and thigh-high stockings hugging the curves of their legs.
Yomogi bounces in first, swaying and jiggling her breasts and belly as she giggles.
"Fufufu... Motegi-chan, I really can't believe you got me dressed like a cow now…"
Chantal follows, swaggering and letting her breasts and belly bounce.
"I already feel like a cow in this, Motegi-kun! And this outfit is so cute!"
Kimberly glides in next, swaying and bouncing her milky breasts and round belly.
"Somehow… this outfit... makes me so... full, Motegi-sama…"
Pinna steps in next, scanning the patterns of her outfit.
"Pattern analysis confirms maximum resemblance to bovine skin. Appropriate for dairy simulation, Master."
Salacia slides in with her eyes already half-lidded.
"Your sea dairy is ready, darling~..."
Manas strides in with her cheeks flushed.
"Verily, this attire will undo my dignity, yet mine loins betray me, for I find mine self… rather exhilarated, mine king."
Lilith twirls, sways, and bounces her breasts and belly with every swing.
"Honey, this is your naughtiest gift ever~..."
Brunhild is last, stammering as the heat blooms on her cheek.
"Th-this attire is… indecent beyond measure, my Lord, yet my body responds most treacherously…"
And I can't help but be mesmerized.
"You all look incredible. Seriously, you're the cutest pregnant cows I've ever had."
Without wasting time, I immediately ask them to do something.
"Take your positions, girls."
They obey, lining up on all fours across the floor. I move down the line, locking each pair of wrists and ankles into the sturdy metal cuffs. Next, I lift the pumps, fitting the soft suction cups over each exposed, eager nipple, adjusting the transparent tubes as they snug against each of their breasts. Once I step back, I ask them again.
"Are you ready?"
"Yes!"
With that, I turn the Wind magic stone on each machine. Instantly, their breast milk begins to flow, slowly at first, then in rhythmic streams through the clear tubes.
Yomogi gasps sharply.
"Ah...! Nnhh...! Motegi-chan…! It's… it's sucking… so gently… but… haaah…!"
Chantal throws her head back, moaning loudly.
"Woah...! Hahhh...! That's crazy, Motegi-kun…! It's like… nghh… it's pulling straight on my nerves…!"
Kimberly's moans follow.
"Oohhh…! It's so… invasive… my body's responding… without restraint, Motegi-sama…"
Pinna stiffens, back arching.
"Nghh...! Master… this… this feels… excessively good…!"
Salacia whimpers in delight.
"Aah~...! Darling, it's so unfair~...! This machine sucks better than you do... mmhh~...!"
Manas clenches her jaw, then moans.
"Guhh...! Nnghh...! Mine breasts… leaking everywhere… melteth beneath thine device, mine king…!"
Lilith's laughter turns to breathy moans.
"Ooohh... honey, is this how cows feel~? I'm so jealous they feel so good every single day, hnnhh~…!"
Brunhild's eyes roll back, her moans shockingly loud and unrestrained.
"Aah...! My Lord… I feel… like a mere beast now... aah…!"
As I watch their reactions, I know that they can play with a little more.
"Looks like you can handle it. Good."
I twist the stone again. The machines' suction doubles; a chorus of shrill moans erupts as the girls' bodies tremble uncontrollably, thighs quaking.
"Aaahh...! It's so intense, Motegi-chan...! My nipples are being pulled so hard...!"
"Mmnn...! I'm already getting lightheaded, Motegi-kun…!"
"Nnhhh...! This machine… relentless… just like you, Motegi-sama…!"
"Sensory overload detected… breast stimulation threshold exceeded… ahh, Master…!"
"I can't take it, darling~...! My breasts... I'm... ahhh~...!"
"Mine breasts… delightfully betray me now, mine king... nghhh...!"
"Hahhh~...! Honey… my nipples... so dirty... so swollen...! Ooh... I love it~...!"
"Nghhh...! My chest… aflame… my Lord…!"
And then it hits them. Together, the eight women scream as their milk flows like broken dams into the tubes, bodies arching and spasming in orgasm.
"Aahhnnn...!! I'm cumming... my breasts are cumming, Motegi-chan...!!"
"Haahhh...!! This milk machine making me cum hard...!!"
"Too good... too much... Motegi-sama...!! Mmhhh...!!"
"Nnnhh...!! Orgasm detected... breast release... output overwhelming, Master...!!"
"My breasts are overflowing, darling~... aahhh~...!!"
"I am undone by thine device... mine king... ooohhh...!!"
"Your machine is doing so well, honey... moooo~...!!"
"My Lord... I'm breaking... I'm... ohh... nngghh...!!"
And yet, I keep the machines going. Their milk keeps flowing, and their bodies keep shaking. Each hard suction cycle sends fresh waves of pleasure crashing through them, their swollen, oversensitive nipples gush more milk and fill the tubes faster. Their moans spiraling into raw, ecstatic screams as fresh waves of orgasm claim them, one after another, their bodies shuddering in unison.
"Haaah..!! Nnhhh...!! Aaah...!!"
At last, I finally flick off the magic stones one by one. They pant with their limbs trembling but held perfectly in place on all fours.
But despite the endless breast stimulation and the flood of pleasure, I know that this will never truly sate them. Since pregnancy, their bodies have changed, and their desires are blooming hotter and deeper with every passing night. So with that, I move to the next step, and this will be the first time I've done this.
I move behind them, and from my dimensional inventory, I retrieve my newest creation from the dimensional inventory, which is a bottle of lotion made from soap ingredients and slime gel, and using my [Hygienics] skill, of course.
I stop behind Chantal, open the cap, and pour a dollop of lotion onto my fingertip. And then, she gasps as I slowly slide my index finger down between her trembling butthole.
"Nyaaa?! W-wait, Motegi-kun, that's my ass!"
"Yeah, I know."
But I keep working slowly, easing my finger deeper and coaxing gently with soft circles, as her confusion and mortification pitch up.
"Nnh... ahh...! Motegi-kun, what are you doing...? Stop it, that's dirty…!"
I continue to work my finger in and out and then add a second finger, twisting gently. She squirms again as the intrusion slowly stretches her open.
"Hey, not there... ah, it's weird…!"
A third finger enters, and she gasps again.
"Nngh... oohh...! Seriously, Motegi-kun, why my butt…?"
Finally, I slip my fingers free, gazing at the way her ring twitches and shines with lotion.
"There we go, now it's good."
"Huh…?"
Then, I pull my pants down and release my swollen, hard cock from its confine. After that I coat my cock from tip to base with another dose of lotion in my palm. Once it's done, I grip her hips gently, pressing my cockhead against Chantal's well-prepared entrance and beginning to push, inch by careful inch, into her tight ass.
"Easy… gotta be careful…"
"Motegi-kun, wait, that's not a place for your cock…!"
Finally, I bottom out and bury my cock deep, making her gasp.
"Oh man… this is so tight…"
"Nnnhhh...! I can't believe you really put it in…!"
Yeah, this is my first time doing anal, as I've never done this to any of them before. It's strange and indescribable until I can't even find words for this new sensation. And of course, I don't need to activate [Infertile] for this one since you can't breed anything through an asshole.
Then, I start to move slowly to feel every inch and pick up the pace.
"So this is anal, huh?"
Chantal's voice cracks, caught between confusion and mounting ecstasy.
"Wha… what is this...? My ass… feels so weird... nnnhh, it's...!"
Once I feel her body is adjusted to it, I take out a long pinching rod from my dimensional inventory. Then, I twist the milking machine's magic stones in front of us, and in a flash, the pumps draw on her nipples in a hard, pulsing rhythm, matching my thrusts and causing her to wail.
"Aaahh...! I'm getting attacked from both ends now...! Ahh... Motegi-kun…!"
Not long after that, I can feel myself on the edge.
"Your asshole is making me cum, Chantal! Argh!"
"Nnhiiii...!! This is not good… my ass… my breasts… burning… they're burning...!!"
I slam my hips forward and spill inside her, filling her ass with hot, thick cum. She screams out, her hips twitching hard as her breasts erupt with milk into the tubes.
Once our orgasms subside, I pull out and watch my semen dribble from her open, stretched asshole. I twist the magic stone off the milking machine, remove the suction tubes from her breasts, and unfasten her cuffs. Her arms and chest immediately collapse, too weak to hold her up. Her head flops to the side, lips parted, tongue out, and a messy, blissed-out ahegao is painted across her face.
As I turn to my other wives, who've been watching me and Chantal since earlier, I can see them stare.
Yomogi's and Kimberly's voices tremble with curiosity.
"That… looked so good, Motegi-chan…"
"I… I can't help but… want to try it... too… Motegi-sama…"
Pinna, Brunhild, and Manas also say the same thing.
"Master, my curiosity regarding this unusual sexual penetration of the excretion hole is increasing. The mechanics of pleasure here are not yet understood."
"That was dirty… yet I find myself unable to resist trying it as well, my Lord…"
"Verily, 'tis a most unusual act… and yet, the intrigue is undeniable, mine king…"
Salacia's and Lilith's eyes are half-lidded, and they bite their lips with want.
"If Chantal is in that much delirium, how could I not want the same, darling~…?"
"In all my millennia, no one's ever done that to my asshole. Now you've got me dying to see what it feels like, honey~…"
"Don't worry, I'll be doing that to all of you tonight."
With that, I move to Manas. I pour more of the lotion onto my index finger and spread her cheeks with my other hand. The moment my slick finger presses her tight entrance, Manas gasps and her body stiffens.
"Ah...! Mine king, truly, 'tis art strange…!"
I swirl her asshole gently, easing in deeper and feeling her shudder beneath my touch.
"By the dragons, 'tis a most bizarre sensation…! Ah... thou art... mmn…!"
Her moan catches at the end as I add a second finger, then a third, stretching her carefully. Then suddenly, Manas throws her head back as a strangled scream bursts from her lips.
"Aaaah... mine king...!!"
Her hips buck wildly, jerking back onto my fingers as she reaches climaxes from my caress alone.
I withdraw slowly and reach for the bottle again, pouring more lotion over my cock and stroking it from base to tip.
Fun fact: the soap in the lotion makes this safer, as it cleans away anything left from Chantal's ass and lowers any risk of infection for my wives.
"Alright, let's do this…"
I press my cockhead to Manas's stretched hole and push forward. Inch by inch, I sink deeper until I finally bottom out and groan.
"Ghh! Asshole is no joke!"
Manas throws her head back again as she gasps.
"Ahh…! Mine king… thy phallus feeleth… greater yet in mine arsehole. I am… so full..."
Then, I clutch her hips and start to move, drawing back and pushing in again. And her moans are back to echo off the walls, breaking into pleasure.
"Oohhh...! Mine king...! 'Tis truly as wondrous as thy usual congress within my loins…! My arse… thou makest it sing...!"
Her praise only spurs me on. I grab the pinching rod and twist the magic stone on her milking machine, jolting the device back to life. It sucks her breasts in time with my thrusts, drawing powerful pulses of milk that splash into the tubes and bringing her to more loud moans.
"Ahh...! Have mercy, mine king...! 'Tis torment... 'tis too good... ahh...! Spare me, lest I shatter...!"
And it doesn't take long for me to reach climax.
"I'm cumming, Manas!"
"Aahh...!! Something hot floweth within mine arsehole...!! And this infernal device maketh it all the worse...!!"
With a final, desperate thrust, I spill inside her asshole and fill her with hot, thick semen. Manas screams out, her hips twitching hard as her breasts erupt with milk into the tubes.
Once our orgasms subside, I pull out and watch my semen dribble from her open, stretched asshole. I twist the magic stone off the milking machine, remove the suction tubes from her breasts, and unfasten her cuffs. Her body slumps instantly, legs and arms useless, her cheek pressed to the floor, mouth open in an unguarded ahegao, eyes rolling.
And after that, I work my way down the line, taking Pinna, Brunhild, Yomogi, Salacia, Kimberly, and Lilith in turn. Of course, I prepare each of them carefully, massaging lotion deep into each tight, trembling asshole before I press my cock in. And each time, I reactivate the milking machine, watching the suction pulse and their milk flow while I pound them.
"Mmhhh...! Master… ahh… this data… is… unexplainable… overwhelming…! Anal… stimulation… exceeding all projections...!"
"Aaahh…! I am defiled in the dirtiest place…! This feels delirious, my Lord…!"
"Motegi-chan... ahh... my ass... my ass is breaking...! Amazing... amazing...!"
"Darling... mmh... I'm going crazy... this is too much... my ass~...!"
"Ohhh...! Motegi-sama… this feels… rougher than usual…! I can't handle… this…!"
"Who'd have thought my asshole's such a great tool~...! If only I'd realized sooner, honey, nnhhh~...!"
And I just repeat the same word all over again.
"Fuck! Anal is so good, so damn good!"
Each time I bottom out and finally release deep inside, filling them with hot, thick semen, their screams ring louder than ever.
"Mmhhh...!! Breast and anal orgasm… detected…!! Full system overload... Master...!!"
"Aaahh...!! My dirtiest place… is purified, my Lord…!!"
"Motegi-chan... your semen... my butt... aaahh...!!"
"I'm cumming from my ass, darling... mmmhh~...!!"
"Ohhh...!! Motegi-sama… this… is way too… intense…!! I'm breaking…!!"
"Nnhhh~...!! I'm addicted... I'm addicted to this, honey~...!!"
After I pull out, twist the stones off, and release the cuffs and the tubes... I watch my semen ooze out of each gaping, ruined hole. My wives slump limply, faces turned to the side, mouths open, tongues out, and ahegao burned across their features. Their bodies are wrecked and twitching after first anal sex, leaving them completely undone.
"That was… really wild…"
However, this night is far from finished because I haven't fucked their pussies yet.
So with that, I put all the milking machines back into my dimensional inventory and bring back our massive, plush bed to the center of the room. Finally, I make all the cuffs vanish with Restore spell before I claim each one of them again...
