After dinner, Motegi and the girls agreed to take a relaxing bath together. However, right now, he stands inside the spacious new bathroom alone because he hasn't let them in yet. Not until he finishes what he was about to do, so they're still waiting outside.
At the center of the room, he has placed a wide plywood frame on the floor, which is shaped perfectly to fit the length of a human body using his [Carpentry] skill.
Then, Motegi begins pouring a large amount of slime gel into the frame. After the slime settles into an even layer, he pulls out a block of Needle Bees' wax and a handful of Bitch Leeches' gelatin and tosses them in.
And just like that, the surface of the slime starts to thicken, and it's surprising him.
"Whoa! It's happening for real!"
There was a reason why he did this. He recently learned that in Acrusse, slime gel is used for children's play, which is shaped into toys by kids using just a tiny pinch of beeswax or gelatin to give it a bit of elasticity. The idea is to make it just firm enough to mold but still soft and squishy. And too much hardening agent will make the gel stiff and unusable.
And in his case?
He dumped in both of them, and both in large amounts.
Which means he has only seconds to shape it before it solidifies.
"Now, let's do this. [Temporary Boost]!"
Without wasting time, Motegi activates [Temporary Boost] and maxes out his speed stat to infinity. In an instant, he puts the frame away into his dimensional inventory and begins sculpting the slime.
His hands are carving out ribbed grooves across the center, rounded chambers along each side, and raised bumpers at both head and foot. The material firms beneath his fingers as he works, but he manages to finish in time.
As the gel finally hardens, Motegi exhales and admires his work.
"Yup, it definitely looks like an inflatable mattress."
Finally, he grabs an empty bottle and pours in another slime gel, sealing it. After that, he raises his voice to call out the girls.
"Yomogi, Chantal, Kimberly, Pinna, you can come in now!"
He chuckles to himself, already imagining how they look when they see his works.
"I really can't wait to see their faces…"
Then, the bathroom door opens as Yomogi, Chantal, Kimberly, and Pinna enter with towels wrapped around their curvy bodies and their hair tied in equal buns. However, they quickly pause when they see something sprawled in the middle of the bathroom, which is his mattress-shaped slab of ribbed gel.
Yomogi asks first.
"Motegi-chan, what is that?"
"Ah, I want to try something new tonight."
And Pinna inspects the strange contraption.
"Analysis complete. No data exists within current records for this configuration or material. The matrix's composition diverges from all previously cataloged constructs. I am uncertain of its function, Master."
Then, he holds the slime bottle and passes it to them, confusing them more as Chantal asks him.
"Here, try this. Coat yourselves all over."
"And what's this, Motegi-kun?"
"Just something fun, trust me."
Despite their confusion, the girls nod and let their towels slip. Four towels drop at once to the floor, revealing their bare skin, thick thighs, huge breasts, and eager eyes. Each girl pours a dollop of gel into her palm, then begins smoothing it over her body, first hesitant, then more generous.
And Kimberly is the first one to realize what that is.
"Motegi-sama… is this… slime...?"
"Yup, you're right."
Soon after, every curve gleams as the girls line up before him, four naked bodies ready and shining. With that, Motegi lies back on the cool mattress with arms outstretched, calling out to them.
"Alright, come here. Chantal, Kimberly, I want you to use your bodies on my arms. Yomogi, Pinna, on my body."
And they obey, with their puzzled expressions remaining as their curiosity overtakes hesitation.
Kimberly kneels at his left side and nestles his arm between her heavy breasts, pressing them close around his skin.
"Motegi-sama… like this...?"
"Exactly, Kimberly. Now move your body up and down."
Chantal mirrors Kimberly on the right, taking his right arm between her own firm breasts and rubbing her chest in slick motions.
"Am I doing it right, Motegi-kun?"
"Perfect, Chantal."
Yomogi stretches herself full-length along his body, her breasts flattening against his slick skin.
"Like this, Motegi-chan?"
"Yes, Yomogi. Just slide your body from my hip to my chest."
Pinna settles beside Yomogi, pressing herself close as her breasts and thighs glide against his side.
"Master, is this the intended configuration?"
"Exactly, Pinna. Just move like Yomogi."
And just like that, their slick warmth, breasts gliding, and bodies moving slowly have made the sensation overwhelming for him.
"Oh, man. This feels so good…"
Chantal giggles as she continues to glide.
"Hehe... This slime is so slippery, Motegi-kun."
Kimberly's breathing grows heavier.
"Motegi-sama… I've never done... anything… like this... before…"
Yomogi giggles, breath catching and moaning as her nipples drag over his skin.
"Ahn… Motegi-chan, my nipples are getting so tingly rubbing all over you like this…"
Beside her, Pinna trembles, teeth biting her lip as her eyes flutter.
"Nnhh... new data acquired, Master. Skin-to-skin lubrication coefficient is exceedingly high. Ahh... direct stimulation of mammary and pelvic tissue, must keep collecting… ahh…"
The increased pleasure also makes Motegi's cock stiffen, rising tall and proud between Yomogi and Pinna's gliding forms.
Yomogi halts, eyes wide and squealing delightfully.
"Motegi-chan, your cock is so big already!"
Then, she wraps her palm around his shaft, beginning to stroke him in smooth, slow pumps. Pinna's hand joins hers, fingers careful and precise as she strokes alongside Yomogi.
"Master, synchronous stimulation has significantly increased penile rigidity. Our actions have effectively induced maximal tumescence. Fascinating…"
Together, Yomogi and Pinna stroke him, palms moving in perfect harmony, not once colliding, their rhythm so seamless it makes him throw his head back and groan in pleasure.
"Yomogi, Pinna! Argh!"
But then, Chantal halts for a moment.
"Motegi-kun, can I clean your fingers too?"
"Of course. You heard me, right? Use your body…"
"Yes!"
Just like that, Chantal lowers his right arm and slides her slick, dripping slit from his fingertips all the way to his elbow, shuddering and moaning.
"Ahh… so good…!"
Kimberly mimics Chantal, pressing Motegi's left arm against her folds and sliding up and down, sighing and trembling.
"Mmhhh… Motegi-sama… this is… amazing…"
Their love juices drip warm and wet onto his skin, mixing with the slick slime, making everything even slipperier.
Suddenly, Motegi gasps.
"Yomogi, Pinna, I'm cumming!"
Seconds later, a huge burst of hot semen spurts into the air, raining down onto Yomogi and Pinna's eager palms.
Yomogi squeals again with delight, palm glistening with his cum.
"Kyaa! Motegi-chan, you came so much!"
And Pinna is already analyzing.
"Sample collection successful. Ejaculate volume exceeds prior averages. Visual and tactile inspection confirms high viscosity, Master."
After that, Yomogi raises her cum-splattered palm, lapping it eagerly.
"Thank you for the meal, Motegi-chan…"
Pinna mimics her, tongue sliding across her own palm.
"Composition is unchanged. Salinity, texture, and taste are as expected, Master. Satisfactory as always."
Chantal stops sliding and turns to Yomogi, wanting her share too.
"Hey, Yomogi, will you share?"
"Sure!"
Then, Yomogi brings her palm to Chantal's mouth, and Chantal moans with pure pleasure as she licks every drop.
"Mmm… it's delicious, Motegi-kun..."
Pinna turns to Kimberly, extending her palm.
"Kimberly, do you want to sample as well?"
"Yes… please… I want to... taste…"
Pinna presses her palm to Kimberly's lips, and Kimberly sucks it clean.
"It's always… wonderful… to share... Motegi-sama's… essence…"
Then, because Yomogi and Pinna made him cum, he silently activates [Infertile] and decides to reward them.
"Pinna, ride me. Yomogi, on my face."
They obey immediately as Pinna climbs on his hips, aligning her slick entrance over his cock. Yomogi crawls up, pressing her knees to either side of his head and lowering her needy, dripping slit right over his mouth.
Motegi reaches up, spreading Yomogi's folds with his fingers and making her squeal in embarrassment.
"Yomogi, your pussy's beautiful. It's twitching and gushing already."
"D-don't say that, Motegi-chan…! It's embarrassing…!"
Below, Pinna steadies herself with both hands on Motegi's chest.
"Commencing downward movement, Master."
Then, she drops her hips in one smooth, decisive motion as his cock spears deep inside her.
"Nnhh…! Insertion complete. Penetration depth is optimal. Master, your cock is reaching my deepest point. Stimulus is overwhelming…!"
And she immediately starts bouncing, quickly building speed as her moans grow louder. In response, Motegi thrusts his hips up to meet hers, cock slamming into her at every bounce.
"Ahh...! Maintaining high velocity... must continue. Data collection at maximum… cannot cease!"
Back at the top, his hands spread Yomogi's pussy wide as his tongue plunges deep into her pussy to lap up her juices hungrily.
"Ahh… Motegi-chan… your tongue… it's so good… so deep…!"
Motegi's voice is muffled as he pulls back for breath, praising both women on top of him.
"Yomogi, you taste delicious! And Pinna, you're amazing!"
Then, he slips two fingers into Yomogi's soaked pussy while his tongue is still circling around her folds, making Yomogi's moan grow louder.
"Aahhh...! Motegi-chan, it's too much...! I can't... I can't...!"
As for Pinna, she bounces even faster, her love juices gushing out, and breast milk begins to spurt from her nipples.
"Movement velocity increased to 130%… response from Master's organ at 140%… further escalation required…! Ahhh... Master...!"
Moments later, he groans as Yomogi and Pinna scream in unison.
"I'm cumming!"
"Aaaahhh...!!"
Yomogi's thighs clamp around his head as he bites her clit, and Pinna slams down to hilt him as his cock erupts inside her and floods her womb with so much semen. Pinna's and Yomogi's pussies squirt all over his shaft and face, respectively, and Pinna's breasts spurt milk messily.
Both women collapse atop him face-first, panting and trembling. He eases his cock out of Pinna's still-quivering slit and gently nudges the two women off his body.
And as he glances at Yomogi's dazed pussy, he can't resist sliding his cock straight into her without hesitation, causing her to gasp in surprise.
"Yomogi!"
"Nnhhhiii...!"
He thrusts into her hard, and with only a few deep, relentless thrusts, she screams again as her pussy squirts a stream of love juices over his shaft and her breasts erupt milk, which keeps happening as he thrusts. And it makes her pussy only get tighter as he desperately tries to fight it.
"Motegi-chan, I'm cumming...!! Aahhh...!!"
"Fuck, don't squeeze me like that, Yomogi!"
And it doesn't take long before he reaches his climax again.
"Argh! Cumming again!"
"Motegi-chaaahhnnn...!!"
He empties another thick load deep into her, filling her pussy until it overflows and squirts love juices again around his cock, while her breasts gush and spray milk everywhere.
When the spasms finally subside, Motegi turns to Chantal and Kimberly, and he can't help himself from teasing them when he sees what they're doing.
"Haahh... haahh..."
"Ah, you can't wait anymore, huh?"
The two women are already masturbating, panting and burying their fingers deep between their thighs.
"Motegi-kun… I can't wait anymore…"
"Motegi-sama… please… I need you…"
"Sorry to keep you waiting. I'm going to hold you now."
With that, he instructs them to do something.
"Chantal, lie down on the mattress. Kimberly, face down on top of Chantal."
Chantal instantly flops onto the mattress, and Kimberly glides over to position herself atop Chantal. The two women squirm as their breasts and pussies press tight together.
Then, Motegi kneels behind them and plunges his cock into Chantal's pussy first, thrusting his hips into her.
"Nnngh...! Motegi-kun, your cock... is so big...!"
After a few thrusts, he withdraws from Chantal and thrusts into Kimberly's soaked entrance, making her gasp sharply.
"Aahhh...! Motegi-sama… you are so deep… inside…!"
And just like that, he keeps switching. First Chantal, then Kimberly, over and over. And sometimes, Motegi presses his cock between both their swollen folds and grinds hard against their clits, making both women jolt and shudder, their voices rising in unison.
"Nnhooo...! Motegi-kun... my clit... my clit...!"
"Mmmhh…! Motegi-sama… your cock... is rubbing us…!"
"Shit, I can really tell the difference! Both of you are incredible!"
As he keeps thrusting, their bodies squish together, their breasts mashed, the slick heat of their skin mixing. Their love juices spill out and pool onto each other's pussies, and their pressed breasts spurt milk that mingles together.
And it doesn't take long for him to finally break again.
"I'm gonna cum, Chantal, Kimberly!"
"Aahhh...! Do it inside, Motegi-kun...!"
"Yes...! Motegi-sama… give us… all of it...!"
"Take it!"
"I'm cummingggg....!!"
He buries himself in Chantal first, pumping thick, hot cum deep into her. As soon as he pulls out, he slams into Kimberly, unleashing another torrent deep inside her. Both women scream as their pussies squirt, their love juices splashing against each other's folds and flowing down his cock. Their breasts erupt with milk, spraying each other's skin as they're climaxing.
Spent, Motegi pulls back and surveys Yomogi, Chantal, Kimberly, and Pinna's bodies that sprawl across the bathroom floor. Each one has his semen dripping from their gaping pussies and falls unconscious with an ahegao expression exposed.
But still, this is not the end.
After Motegi and the girls take a bath, they move to the bedroom for round two.
And once they're inside...
"Aaahhhhnnn...!!"
The girls moan over and over again as he continues to pound them and brings them to climax throughout the night, enjoying their first sex in the new house.
