Succubus Mona's Fleshly Remodeling: Lactation and Anal Awakening (Part 1)
Tap… tap… Down the dark, dim stairs and passages leading underground. Emilia, stripped completely bare, descends barefoot, pushed along from behind by Mona. The stone steps are mercifully smooth, without much unevenness. Back in her adventuring days, she'd often dashed across meadows barefoot, so there's no real reason to complain about this. Of course, the cold chill of the stone seeps up through her soles, sending a sharp shiver through her body…
It's been a while.
This is her first time down here since that initial body modification when the lust worms were implanted. She'd undergone plenty of training sessions with Mona, but they'd never ventured this deep. Hypnosis to toy with her mind, injections of all sorts of sexual knowledge… those had mostly happened in Emilia's own bedroom. So this underground passage, revisited after so long, felt strangely unfamiliar.
Tap… tap… The stairs end before she realizes it, and they arrive in that dimly lit basement level she's seen before. Stone walls stretch out like a maze, and beyond the sinister iron doors scattered here and there, she hears women's moans—lewd cries and sobbing whimpers much like before. But Emilia can sense the sweet undercurrent of pleasure woven through every one.
Ugh… something… feels…
Rub… Emilia rubs her thighs together and hugs herself with both arms. Heat rises in her groin, and her exposed breasts feel feverish with arousal. The chorus of lascivious voices from all those women echoes through the enclosed underground space, as if deliberately stoking her dormant desires. Ah, if she keeps listening like this… she'll definitely lose control and start masturbating…
"Hehe, Lia. You look like you're enjoying yourself."
"…As if."
"Oh? Is that so~?"
Mona slips up behind Emilia's slender shoulders and whispers right in her ear. The succubus's voice carries a special resonance, fanning the excitement already simmering inside her even higher. Emilia grits her teeth hard, turning her gaze away to hide her arousal. Mona hums a tune right by her ear or keeps chatting away, and Emilia struggles to resist the magic laced in that voice as they head to the innermost chamber of this underground prison.
Groooan…! Creeeeak—!
The heavy iron door swings open on its own at Mona's gesture, revealing the prepared room. It's the very same chamber where Emilia first accepted the lust worms—the site of her initial remodeling. The dark, humid space, thick with a strange atmosphere, fills her vision. For some reason she can't fathom, Emilia feels pushed inside by Mona.
As Emilia steps in, parts of the stone-like walls and floor writhe and shift. She realizes they're not mere stone at all, but some creature masquerading as such. The same wriggling tentacle monster Mona had used for her previous modifications.
"Mm~ Hm~♪"
Mona hums cheerfully as she gets to work. She drags Emilia to the center of the tentacle mass disguised as the stone floor, securing her legs in place. She summons tentacles from the ceiling to wrap around Emilia's arms and hoist them upward. Emilia ends up restrained with her arms raised high, legs fixed to the floor, in an awkward pose—thrusting her breasts forward, ass pushed back. Bent slightly at the waist, it leaves Mona looming over her.
"Perfect, all set~."
"…What are you planning today?"
"Oh~ Something fun. Just a little treat to add more pleasures to our Lia's repertoire~."
Mona dodges the point, teasing as always. Emilia doesn't particularly care to know, so she doesn't press. Still, being stark naked in such a humiliating position chafes at her.
Mona strokes the immobilized Emilia's cheek, plants a kiss on her face, showering her with light affections. Her hands glide over Emilia's plump thighs and the generous peach-like curve of her ass. Every crawl of Mona's fingers across her skin sends delicious shivers racing through Emilia's mind. But it's all just superficial, teasing contact for now.
A moment later, accompanied by a rattling clatter, a cart—called a tray—rolls in. Pushing it is what looks like a golem made entirely of inky black shadows, one of Mona's creations.
"Great, it's here. Today's tools. Tadaaa~!"
Mona shows off the items on the tray with theatrical flair. Transparent glass vials filled with unknown reagents. Pincers of mysterious purpose. Syringes and assorted odds and ends—none of it immediately obvious from a glance.
Among them, Mona uncorks a vial of reagent and brings it close to Emilia's lips.
"Drink up, Lia."
"No… Ugh… grk…."
"That's it, good girl. It's a succubus secret potion—don't spill a single drop~."
"Mmmph… gulp…."
Mona's command carries an irresistible compulsion. Unable to resist, Emilia swallows the entire contents as the vial tilts against her lips.
"Ah… haa… haa…."
Once the vial is drained, Mona pats Emilia's ass approvingly—"Good job"—and picks up another reagent from the tray. This one's different in size and color from the first. Uncorked and tilted, its thick contents pool generously in Mona's palm. She smears it straight onto Emilia's exposed breasts.
"Oh, what perfect tits… I just love them…."
Mona gazes at Emilia's breasts with affectionate eyes, like she's admiring something precious, slathering the viscous liquid over their firm curves. Once coated sufficiently, she pours more into her hand and layers it on thick. The sticky reagent clings heavily to every inch of Emilia's breasts. Some overflows, trickling down her stomach or dripping to the floor in long strands.
"Haa… haa… haa…."
Emilia pants raggedly. Mona's obsessive kneading has her aroused already. But it's not just the stimulation— that strange potion Mona forced down her throat earlier is kicking in. Midway through drinking it, a burning heat ignited deep inside her breasts, in the fatty tissues themselves. The topical reagent sinks into her taut flesh too, heightening the sensitivity with every absorption. And to make matters worse, that inner heat surges stronger from the ingested potion…
"Ngh, ugh… uuugh…!?"
Emilia senses something bizarre building inside her breasts—like they're filling up from within. A swelling pressure, as if the whole mass might balloon taut and burst. A heavy, insistent presence she can't make sense of. It grows relentlessly, bloating larger, making her half-convinced her tits might actually explode if it keeps up. Her breasts were already perky and firm without a hint of sag, but now they pulse with even more vigorous bounce and weight. And if she's not imagining it, they've grown just a tiny bit larger…
S-so… stuffy… something… ugh…
The tips… itch so bad…
"Ehehe~ Hm hm hum~♪"
Mona hums merrily, cupping Emilia's newly weighty breasts from below and kneading them. Their sensitivity has multiplied several times over—mere squeezing feels like direct nipple play. Watching Emilia's reactions, Mona reaches for yet another vial. This one contains several skewers. Thick like spits, but coarser than ordinary ones. Emilia's eyes flicker with unease—she's experienced something similar before—but Mona reassures her it's different this time.
…Not that it offers any comfort…
With the vial still open, Mona reaches for Emilia's breast, teasing and tickling the nipple. The reagent seems laced with an aphrodisiac; Emilia's nipples stiffen to their limit in moments. Satisfied, Mona grins and picks up a skewer dripping with the stuff.
"Lia, Lia. Guess what I'm about to do?"
"…I don't want to know."
"I'm gonna shove these secret reagent-soaked skewers right into your nipple holes. Deep into those milk ducts meant for feeding babies."
"Shut up! I said I don't want to know!"
"Listen, listen~ This'll make your tits produce sweet, sweet milk~."
Mona dangles the dripping skewer before Emilia's eyes, then grips one breast, pinning the nipple steady with her fingers. She presses the soaked tip against the center and applies gradual pressure. Emilia distinctly feels the sharp point invading the cluster of sexual nerves in her nipple.
As she does, Mona continues with a wicked smile.
"That potion you drank earlier, the one I slathered on your tits."
"And this skewer I'm stabbing in now."
"It's all~ to make your breasts gush delicious milk."
"To turn you into a body that can lactate endlessly, even without bearing a child."
"So be happy, my darling Lia—rejoice lots and lots."
Mona announces it all with evident delight, then thrusts the skewer deep into Emilia's nipple in one smooth motion.
