The Librarian Magical Girl Becomes the Sadistic Master’s Concubine [Simulated Dismemberment, Ovum Eating Show, Mars’ Harem, Pain/pleasure Sharing]

Foreplay was unnecessary.

Seri’s nether regions, already thoroughly soaked in alcohol and aphrodisiacs, glistened with vaginal fluid, and as if she were having a wet dream, faint moans were already escaping her lips even before penetration.

As he peeled off the swimsuit that showed her cameltoe, a string of honey-like fluid stretched between the swimsuit and her twitching petals, and Mars, who had been eagerly waiting, couldn’t hold back and slowly thrust his hips in, swallowing hard.

“…Ung-at♡”

“Haa…I’ve waited a long time, Seri-ya…”

Jjeugeugeugeuk····

Sex after a week. And unhindered penetration.

Due to the Mana-Dissolving Liquor, her protection skill couldn’t activate, and at the thought of filling Seri’s defenseless, sleeping womb with his seeds, Mars felt like he could ejaculate throughout this entire vacation.

If he put his mind to it, he could actually do that.

Every time he stole Seri’s vast Magical Power, which was almost infinite, his stamina didn’t deplete; instead, it recovered, so there was no chance of his energy running out.

“Ung, heua-eung….♡♡”

“You’re feeling it even while sleeping? You’re incredibly lewd…my girlfriend-nim?”

Even though her protection skill was locked, her Negative Skill was still active, allowing Seri’s shrunken body to effortlessly swallow Mars’s arm-sized member.

With the 『Dick Case』skill, which transformed her body to fit his dick, her belly distended outwards all the way to her navel, giving her a slightly grotesque appearance from the outside, but…

For Mars, who had somewhat reverted to his past tendencies due to Hyun-ah, it only served to excite him even more.

“Is this your cervix? Huh? Seri-ya…”

“Hunyaaaat…♡ Ung, he-eut♡♡….Pussy, I like it…”

Kku-uk kku-uk.

As he gently pressed her distended belly with his palm, Seri’s hips arched up like a live fish, even in her sleep.

Afterwards, Mars covered her shrunken body with his own, using 『Body Adjustment』, and his much larger male body settled between Seri’s widely spread legs.

Even in the breeding press position, optimal for pregnancy, Seri remained in a deep sleep, but sweet moans escaped her lips every time his dick was thrust in all the way.

“Heu-eung……!”

“You came in your sleep? Oh, how admirable, how admirable~.”

Her body stretched out and trembled. Mars received all the vibrations from her small, hot body, and as if responding to her tightly clenching vagina, he spurted out semen.

Semen saved up for this day. Even though he didn’t know if she would truly get pregnant without her skill, he poured the thickest, most viscous milky fluid directly inside Seri.

“····♡···!?”

Umjjil, umjjiiiiiil····!

The upper part of her belly, where the shape of his dick was clearly visible, swelled up like a pregnant woman’s, and Mars pulled out his member while the semen was still flowing back out of her womb.

And then…

“Ung-ooooooh──♡♡♡♡”

“Oh, she woke up, she woke up.”

Perhaps wanting to quickly empty her and re-insert, the beast’s impatient hand ended up pressing her swollen belly.

Then, semen, enough to make it seem like Seri was ejaculating, spurted out like a fountain, and the pleasure, intense enough to burn her brain, caused Seri to finally wake up.

“Mars, Mar-s, Mar…s…?”

“Did you sleep well~ After drinking like crazy, what do you mean by sleeping alone, you punk~ I didn’t get to enjoy anything.”

“Heh, euh…het? What did you just say…”

Seri, who seemed sober, as if the recent pleasure had even sobered her up.

But her waking up only made things better; once Mars started to rampage, there was no one in the room who could stop him.

“Sorry, Seri-ya~ I almost had a terrible thought, you know? Some clingy bitch tried to seduce me right after you passed out, didn’t she?”

“So, while I was fucking you, I was giving her a bit of punishment in my own way. Though it seems that bitch is dying of pleasure from it.”

“…Huh? What do you mean…Hiiik?! Hey! What did you do!?”

She couldn’t help but be horrified.

Right next to Seri’s head, where she had been lying. If anyone saw a face that looked like it was about to die from pleasure, with its limbs completely gone, they would surely fall over in shock.

Her limbs were literally invisible. If Mars hadn’t casually told her not to worry and hadn’t moved the sub-space warp rings fixed to Hyun-ah’s limbs, Seri would have momentarily thought Mars was cruel.

“Well, it’s something like this.”

“Ah, good morning…Sunbae-ssi…”

“Haa…I was really surprised…”

Seri couldn’t understand why Hyun-ah still seemed to be lost in the afterglow of climax.

After all, she was the only one who had been fucked. Since Mars wouldn’t lie, Hyun-ah had only voyeuristically watched while in an onahole state.

“Eheheh…Sunbae-ssi…You’re not actually worried about me, are you? I’m so happy…At first, you tried to kill me with a card, and my heart ached so much…Heuk heuk…”

“Wh-who said I was worried! I didn’t do anything like that!?”

“Anyway, you’re fucking too kind, you know? How are you going to live in this world if you’re so naive, honestly…”

“I’m not kind! I’m not naive! Stop gaslighting me~!!”

Feeling underestimated, Seri sat on Mars’s lap, fuming.

Yet, perhaps uncomfortable with the cum-soaked dick touching her back, she adjusted her posture, straddling the dick between her legs like riding a saddle, and sat cross-legged.

“Oh~ While you’re sitting, clean it up a bit.”

“…Heung, I don’t know.”

“If you don’t want to, should I make her do it? I just need to grab her head and move her… Even if it’s annoying to move her, it feels really unclean…”

“Ah, no!”

Kkyu-uk…

“…It’s mine.”

“”….Puhat!””

“D-don’t laugh!”

The two people burst into laughter at the sight of her hugging his dick tightly and preciously.

Regardless, Seri began cleaning the glans of the member that had mercilessly stabbed her body just moments ago.

········Jjok.

Kkaljjak, Chureureup····Jjyureup····

“Nyereup…Chup, Jjyureureureup..”

“Ah…this is good, good…”

It was fishy, bitter, and formed clumps like soft tofu every time she took it into her mouth, making it incredibly hard to swallow.

Because she had shrunk, her tongue and mouth had also become smaller, and she couldn’t open her mouth wide enough to take his dick in, so she could only suck on it like a lollipop.

‘The smell of semen…it’s too strong…♡’

‘The scent from Mars’s body is also so good♡♡ I feel like I’m getting addicted..♡♡’

Seri gently held the glistening glans like a handle, and carefully cleaned his dick, moving it like a crane lever.

But such small stimuli only felt good at first, as she always desired something more intense than before.

“Hey…is that cleaning?”

“Mueu-eup─?!”

“I’m letting your lower pussy rest, so shouldn’t you scrub it hard with your upper pussy…Huh? Seri-ya.”

Even with the Negative Skill, there seemed to be a limit to body transformation, as swallowing only about half was her maximum.

Hyun-ah, whose senses were also linked with Seri, couldn’t breathe even though her throat wasn’t blocked, and her face, which had only been frowning at the intense male scent, gradually distorted.

Furthermore, perhaps because she couldn’t clean it to his satisfaction, Mars turned her over, flipping Seri’s legs, which had been in his lap, onto his shoulders.

“Ogogok···Hu-up····Ogeut?!”

“Oh, now this feels good.”

Pakpakpakpak!!

Seri urgently slapped her thighs, as if she was running out of breath.

Only then did Mars grab Seri’s head and lift her up, and for a short while, Seri and Hyun-ah quickly caught their breath.

“Haa…haa…Mars, you crazy bas─

Jja-ak!!

“Kkeuhyaaaaaang♡♡♡Don’t hit my butt····Kkyah heuk♡”

“Open your mouth quickly~ Before I flick your clit~.”

Her butt, drenched in sweat and bodily fluids, took on an appetizing apple-like hue, and Seri, after resisting and resisting, finally couldn’t bear it when he tormented her pussy with his fingers, and had no choice but to take his dick into her mouth again.

Seri was slightly flustered by Mars’s appearance, which seemed like something she was seeing for the first time since Black Rose, but she was satisfied with the more intense and coercive sex than usual.

Like when her face was submerged in the bathtub and she couldn’t breathe in the past. She rejoiced in the feeling of being restrained and bound to him, spurting out gushes of fluid.

On the other hand, Hyun-ah seemed overwhelmed even by the stimuli they felt together every day, and compared to the relatively relaxed Seri, she could only gasp and twitch her hips.

“Seri-ya. Do you think I’d abandon you?”

“Paha…What are you suddenly talking about, stopping me from sucking?”

“No~ Do you think I’d like another bitch more than you~.”

Seri also knew, as she was registered as Hyun-ah’s master.

What kind of skill she had acquired, why her senses were linked with hers… If so, she could guess what Mars would say next.

Even if she was already recognized as the official wife, even if she could get pregnant first…

She hated even imagining this man with another woman…especially with Hyun-ah.

But that was Lee Seri’s human concept of chastity. Although Mars had been accommodating Seri, polygamy was extremely common and ordinary for Clausin, for whom it was not illegal.

“……………That promise…you have to keep it, right?”

“If you don’t keep it…I’ll cry my eyes out my whole life. I’ll cry loud enough to make the world leave…Got it?”

“…That won’t happen.”

“Tch…You’re cheating, but…at least use a condom. Got it?”

“I wonder if there’s a size that fits.”

Seri, puffing out her cheeks in a pout, went under the bed to see what was there, and soon, with a cry of “Found it!”, she came back onto the bed with several tools.

“Waa~Sunbae-ssi has finally accepted me! Yay~Hooray~!”

“…Hyun-ah. I still have no intention of forgiving you, you know?”

“Aww, you even prepared condoms~ I know you’ve already calmed down inside, you know?”

“No, I’m serious, it’s not! Does this look like a regular condom?”

“You put a hole in my master-nim’s belly, who is like the heavens… You almost killed my man, and you thought I’d just let it slide?”

“I heard from Ciel that you, Hyun-ah, aren’t a complete Demon of Lust yet…”

“Tteukkeum..”

Indeed, she had no wings, tail, or horns… That must be why she hadn’t yet broken free from the mold of a Magical Girl.

“I guess I’ll make you one today. Right, Mars?”

As Seri grinned wickedly and peeled open the condom wrapper, what emerged from the wrapper was far from an ordinary condom.

It was made from a highly elastic Wall Roper, imbued with a Negative Skill that allowed it to absorb a great deal of Magical Power from ovulating eggs, and a condom that could eat those eggs and convert them into the wearer’s Magical Power.

“…This is seriously disgusting.”

“Well, it suits our utterly wild boyfriend-nim perfectly~.”

Even though the condom was initially the size of a coin, once it completely covered Mars’s dick, thread-like purple tentacles squirmed, and in the meantime, Seri showed Mars Hyun-ah, who was standing by the bedside, and gently hugged her from behind.

“Th-that, Sunbae-ssi…? If that’s actually put in, won’t I die…?”

“Eung~ You won’t die. I’ve been fucked for eight hours, and it just stops at the point where your brain feels like it’s burning to death★”

“Isn’t that basically dying?!”

“Alright…now shut your upper mouth. Oh, and that Roper Condom, if you don’t ovulate eggs, it’ll crawl all the way into your ovaries, so you need to be wide awake, okay?”

“Neeeeeeh?!”

I told you, it’s punishment.
