Lewd Dungeon Master: This Orc Is Too Damn OP!-Chapter 257: An Angel’s Scream

"You put magic stones in there...? And it worked?"

Shaitan, who rarely changed her expression, openly stared at Gremory with a face full of shock and horror. Gremory was trembling while drooling saliva and love juices, and I kept pushing with my dick so the mid-grade magic stones wouldn’t come out.

"Yeah. Apparently the magic stones turn into mana the moment they go in? Well, I wouldn’t know, but that’s what she said. Hngh."

"My goodness."

Shaitan crouched down and placed her hand on Gremory’s lower belly. Even though my dick was going back and forth inside Gremory right below, Shaitan was amazed that the magic stones were turning into mana inside the vagina.

"Mana really is being absorbed into the body. This...is essentially the same as experience points going up in the system."

"Yeah? Why?"

"For witches and mages like Gremory, the measure of their power changes depending on how much the mana in their body increases."

"Is that so? Hehe, looks like I really struck it right."

I just tried it and hit the jackpot. I lifted Gremory up and flipped her body over so she could absorb mana more comfortably.

"Ah, ahh, too much, too much...!"

Gremory was going crazy with a flush spreading across her whole body. Her voice was properly loosened up and she was feeling it better than ever.

"Master, how did you discover this?"

"I just thought of anal beads and shoved them in, and the reaction was killer. I never imagined they’d absorb mana though."

"Hmm.... Gremory, excuse me."

"What, what?! You too, eehiit?!"

Shaitan began gently rubbing Gremory’s clitoris with her index finger. As Shaitan’s white finger was placed on the black clit, the color contrast was stark.

"I’m reading the flow of mana. Please bear with me for a moment."

"I, I, I’m forced to cum every time I’m, I’m stabbed, uhaak!"

"For someone saying that, you’re enjoying it quite a bit right now. Hmm...I see. I’ve figured it out."

Shaitan took her hand off the clit and began rubbing back and forth under my dick with her palm. She stimulated under my urethra as if telling me to ejaculate right now, and I adjusted my posture to do as Shaitan wanted.

"Then here comes the mana injection?"

Spurt, spurt.

My dick swelled and instantly a massive amount of semen filled Gremory’s insides. Gremory couldn’t even scream, just hung her head and passed out.

"Ooh, I see."

Shaitan wiped my semen flowing out of Gremory’s vagina with her index finger and smiled broadly.

"Master’s semen melts magic stones!"

"Is that how it normally works?"

"No. It seems Master is special."

Shaitan grabbed a lowest grade magic stone and began rubbing it with my semen on her index finger.

Pssss.

Then the magic stone began losing its form as if its shell was peeling off, and soon became a thick liquid sparkling with starlight.

Lick.

Shaitan put her tongue to it without any hesitation.

"!!"

Shaitan’s eyes went wide. Her wings and tail stood up straight in surprise, and soon she gulped down all the liquid sparkling with starlight in a way that could only be described as ravenous.

"Haah, haah."

Shaitan looked up at me with enchanted eyes. The sticky liquid on her lips sparkled, making her look just like she’d given a blowjob.

"This...is revolutionary."

"Revolutionary?"

"The magic stone’s mana is contained intact. This way, there’s no need to extract mana from magic stones...no need to forcibly synthesize by turning magic stones into life."

"What."

It was nothing short of shocking and horrifying.

"Really?"

"I have no reason to lie."

"It’s just hard to believe. So, so let’s organize this."

Just as Shaitan was surprised, I was also so shocked I could faint. I made an experimental plan to verify Shaitan’s hypothesis.

Experiment 1. Was this something that happened by chance just once?

"First, let’s experiment until you can be certain. Shaitan, go get a few low-grade magic stones we got from touring the sub-dungeon."

"Ready."

Before she finished speaking, Shaitan grabbed several magic stones shoved in the warehouse. Compared to mid-grade magic stones, the size was small, about the level of somewhat pretty pebbles.

"Hey, Gremory."

I laid the passed-out Gremory on the bed. Gremory remained unconscious and passed out, and I opened Gremory’s slit left and right.

"I’m putting in magic stones."

Gremory gave no answer. I would have put them in even if she said no. Because Gremory was the most optimized woman for this kind of experiment.

’It’s a hole that could fit two or three magic stones at once.’

It seemed like Gremory’s hard work rolling around all these years was finally paying off now. With the situation like this, Gremory’s wide hole that had plenty of space even with my massive cock inside looked almost pretty.

"First, experiment number one."

Can only one magic stone be absorbed at a time? I consecutively shoved two low-grade magic stones into Gremory’s insides.

"...Ugh."

Gremory let out a slight groan and frowned. The lower the grade, the more angular the magic stone’s form became, so it seemed to hurt as it scraped the vaginal walls going in.

"Shaitan. Pain relief. Pleasure conversion."

"Then the converted pleasure will decrease too."

"It’s fine. She felt so much earlier, she needs time to rest now."

The moment Shaitan placed her hand and used sex magic, Gremory’s expression began to relax. I stuck my fingers deep so the magic stones couldn’t come out, then rammed my dick in.

"Whew...."

Maybe because I’d already pounded her several times, Gremory’s vaginal walls were soft like tofu. I felt it occasionally, but I could understand why Gremory insisted on using her clone.

’After pounding this much, it’d be better to stick it in her armpit.’

It seemed like she needed a lot of time to recover if done for too long. But still, I kept shoving my dick in repeatedly.

Squelch, squelch.

"There’s a reaction."

Shaitan put her ear to Gremory’s lower belly and slowly began moving her hand. With movements like healing hands, I had no choice but to slowly thrust in and out.

Squish, psssh.

Gremory’s vaginal walls very laboriously pulled at my dick. Even with all her strength drained, the vaginal pressure trying to tighten to stimulate my dick was pitiful.

"Shaitan. Is there also sex magic that forces ejaculation?"

"Uh...there’s magic that temporarily causes premature ejaculation. Master, that’s a bit."

"Do it."

For the experiment, and for Gremory’s stamina, I decided to temporarily become a quick-shooter myself. Shaitan made a tearful face and reached her hand toward my dick.

"Please know this first. I want to do it with Master for a looong time."

"Just make me an endurance guy in the dream."

"...Aha!"

Shaitan understood immediately. And as soon as I received Shaitan’s help, my dick hurt like it would burst.

"Ugh?!"

I had no means to endure. Unlike before, the moment I thought ’I’ll hold it,’ my dick was already panting and starting to spurt semen.

Spurt, spurt.

"Now...!"

Shaitan climbed on top of Gremory and began stimulating her clit with her tongue. With her eyes even closed, gently rolling the bean with her tongue looked almost like a solemn ritual.

Squelch, squelch.

Gremory’s insides accepted all my semen without any trouble. Her pussy was so wide that it wouldn’t leak out even if I didn’t plug the hole with my glans.

"Hmm, I see...."

Shaitan kissed Gremory’s lower abdomen and raised her head. As she naturally opened her mouth wide, I unknowingly pushed my dick into Shaitan’s mouth.

"I’ll clean it for you. Slurp, suck."

Shaitan’s tongue wrapped around my dick. And I immediately sensed something was wrong.

"Wait, wait a minute!"

I’d just ejaculated and didn’t even have time to feel the afterglow. I grabbed Shaitan’s horns and tried to pull her head away, but Shaitan set anchor-like teeth and bit down on my glans, so I couldn’t push her away.

[You haven’t done it with me lately.]

"No, that’s because I’ve been busy...don’t talk through the system! Ugh?!"

Shaitan rolled her eyes upward and smiled slyly. Then immediately opened her mouth and tilted her head back.

"The first experiment was a success. Regardless of the type of magic stone, the stones turned into mana and were absorbed into the body."

Shaitan spun her body around and lay down next to Gremory. Unlike the naked Gremory, Shaitan maintained her business suit and pulled her skirt up while raising one leg high.

"Second experiment. Does it work on other subordinates besides Gremory...?"

"Can’t I just call Lune then?"

"Master."

"Alright, alright."

How could I tell her not to when she seized the opportunity the moment it came? And not for anything else, but for a woman spreading her legs like that, expecting me to pound her.

"Hold on."

I used the angular part of a low-grade magic stone to make a hole in the executive officer’s stockings. The moment I made a small hole, I immediately stuck my finger in and pulled it apart left and right.

"Looking at it like this, the contrast is clear."

An ordinary witch but worn and dark brown.

A pro in dreams but a succubus only used by me, pink.

I felt somewhat sorry for shoving a magic stone into Shaitan’s insides that no one else had touched, but since Shaitan herself earnestly wanted it, I had no choice.

Squelch, squelch.

"Hyaaah...."

The moment the magic stone went in, Shaitan let out a moan and pulled her legs together. She was quite afraid of feeling pain, so I’d already converted it to pleasure, making me realize the pain of the magic stone entering the vagina was considerable.

"Should I stop?"

"N-no.... The pleasure conversion is stronger than I thought, ugh."

Shaitan bit her lips and tilted her head back. I used the flat surface of the magic stone to slightly press and move against Shaitan’s vaginal wall.

"I learned something playing with Shax. No matter how pleasurable, if it’s repeated too much, beyond limits, that becomes painful too."

"Don’t, don’t do that...!"

"I have no intention of hurting my women. If it hurts, say it hurts."

"...Yes."

I straddled Shaitan’s leg as she wanted. With her raised leg placed on my shoulder, I slowly pushed my dick into Shaitan’s pussy twisted at 90 degrees.

"Ugh."

"Slowly."

I pushed my glans in little by little like a turtle crawling. Not just because Shaitan was in pain, but I felt like I’d immediately cum from the premature ejaculation magic.

"Whew, whew."

Even strengthening patience wasn’t very effective. Even with just the glans fully in, Shaitan’s pussy tightened as if to crush my glans. The magic stone that went in before the glans seemed quite stimulating.

"Shaitan, let’s add one hypothesis to the experiment."

I pushed the glans in just a bit more, then gripped my shaft as if masturbating. When I didn’t move, Shaitan looked up at me with hazy eyes.

"A, a hypothesis?"

"Yeah. We’ve already confirmed that magic stones covered in semen turn into mana. Then...what would it feel like to shove it back into a pussy full of semen and melted magic stones?"

Slap slap slap slap!!

I shook my hand back and forth faster than ever. It was quite ironic to masturbate with just the glans stuck in a woman’s pussy, but this drove a person crazy in its own way.

’It’s like using Shaitan as an onahole.’

Even if used like an onahole, only I should use her. Even the derogatory term ’cocksheath’ should be an expression only I can use. Setting aside the seal and being the Demon King’s daughter, the woman named Shaitan is wholly my woman.

"Shaitan. You’re mine."

Mine that I can’t hand over to anyone. To clearly leave my mark on Shaitan, I released my ejaculation urge without hesitation.

"I’ll fill you up inside as much as I love you."

"Ughhh?!"

Shaitan clenched her teeth and trembled all over.

Psshhh!!

Semen spurted from my glans into her pussy. Without time to feel the afterglow of ejaculation, I pushed my still-hard dick inside along with the semen I’d just shot.

"Hehe, experiment successful? The magic stone’s melting?"

Squish. Beyond the sticky semen, the soft feeling was definitely the melting magic stone, not Shaitan’s cervix. Shaitan’s leg fell to the side, and Shaitan smiled dopily with a face melted like the magic stone.

"The, the experiment’s not over yet...."

Shaitan staggered and raised her butt.

"The efficiency of mana absorption while the magic stone melts...and...."

Squelch.

Shaitan used one hand and her tail to spread her anus left and right.

"In, in the back too if it’s possible...!"

"Fuck, absolutely."

I took the roundest magic stone, thoroughly covered it with the semen on my dick, then shoved it into Shaitan’s anus and grabbed her tail to push it in.

"Eehiiik?!"

"Try shoving it in yourself, ugh. If you’re faster than me, I’ll pound your ass too."

"That, that’s, hyaaah!!"

I rammed my dick in at full speed. Good Shaitan, hoping to get pounded in the back hole too, shoved her tail in like a dick herself while burying her face in the pillow.

Thwack thwack thwack thwack!!

"Kyaaaaaah...!!"

Shaitan and I opened our eyes to new play.

Though the magic stone absorption experiment through the anus ended in failure.

***

"It’s been a while since I fucked like a storm. Then let’s see...hm?"

"Ah."

Was it because I came back after dealing with Vapula dungeon’s hidden boss? The unfortunate angel who’d been subdued by Vapula once, Valac, made eye contact with me the moment she opened her eyes.

"This, this is...."

...She made eye contact with me wiping off the starlight-mixed semen flowing out every time the tail twitched, after pulling the tail out of the passed-out Shaitan’s back hole.

"Kyaaaaaaah!!!"

Valac’s scream swept through the entire dungeon.
