Chapter 351: Enhancement
"What makes you think today will be any different?"
"It will be! I know it will. So please, hurry...!"
Lucifer glared up at me with fire in her eyes. I grabbed her face with my own hands and pulled her out of Flauros’s roots.
"Hehe, you’ve been thoroughly marinated."
Lucifer was naked, her entire body sticky with the roots’ mucus. Flauros, ever tactful, presented Lucifer to me by simply lifting the tentacle lodged in her rear end straight up.
"Now then, time for today’s gacha pull..."
Whoosh.
Lucifer spread her legs in an M-shape toward me. This was an assertiveness and boldness I’d never seen from Lucifer before, and I wondered what could have possibly happened in the span of a single day.
"What’s gotten into you?"
"I’ll do my best. I’ll produce a high-grade stone no matter what and repay your grace, Master. So please, just don’t put me back in the roots... hic."
Lucifer hung her head and shed tears. I turned to look, wondering what on earth had happened to her inside those roots, but Flauros just scratched its stump with a tentacle.
"Hehe, seems like you and Flauros are a match made in heaven."
"No! N-No, that’s not, nngh...!"
The dick tentacle supporting her rear began to squirm violently. Lucifer trembled all over, tears and drool streaming down her face.
"Ah, I see. You’ve been pushed so far over the edge that you can’t take it anymore."
"I’m, I’m sorry... I’ll produce a high-grade magic stone, so please take me out of here... I’ll turn the next prisoner who comes into the training room into an even worse state than me..."
"Yes, that’s the spirit. A trainer should have that kind of ruthlessness."
Lucifer had finally embraced her role. For the sake of the training room’s future residents, Lucifer needed to adopt a new mindset as the training room’s senior veteran.
"Remember everything that’s happened up to today. You are my magic stone-producing machine, Shaitan’s handmaiden, and the administrator of the training room."
Other Seal bearers would be coming here in the future. Lucifer would thoroughly train them based on everything she’d learned up to now.
"Flauros, release her. And give her a rinse."
Grrrl.
Flauros swallowed Lucifer back into its roots. The look of utter betrayal on Lucifer’s face lasted barely ten seconds before she was spat back out.
"Huh...?"
"I said a rinse, didn’t I?"
The roots had sucked away every trace of foreign matter clinging to Lucifer’s skin. She was as clean and fresh as if she’d just stepped out of a bath. I grabbed Lucifer under the arms and hoisted her up.
"Let’s see if you can produce a high-grade stone on your own. I’ll just sit back and do nothing."
"Y-Yes!"
Lucifer immediately knelt before me and bent forward. Then she pulled down my pants and took my rock-hard member into her mouth.
"Nngh."
Was this the fruit of sheer effort, or had Flauros trained her well? Lucifer’s oral technique had become incredibly refined. It wasn’t just skillful; her tongue moved in a way perfectly tailored to mine.
"Leaving you to Flauros was the right call. You’ve been developed into my personal mouth-pussy, haven’t you?"
Nod.
Lucifer answered by licking the head up and down with her tongue. Shaitan, watching from the side, frowned coldly at Lucifer.
"Tch. She’s weak."
"How so? Mmm, feels great to me. When it comes to oral, she’s got to be in the top five in our whole legion right now. Hehe."
Whenever Shaitan criticized, Lucifer’s tongue would stiffen; whenever I praised her, she’d bob her head even more eagerly. Lucifer seemed to be the type who tried harder when given compliments.
"Her technique as a mouth-pussy is certainly comparable to mine, as you say, Master. She is my sister, after all. But it’s not enough."
Shaitan approached from behind me and slid her hand downward. Lucifer was startled to see Shaitan’s hand appear before her eyes, but I savored Shaitan’s touch, and as the missing something was filled in, a thrilling heat surged through my balls.
Squish.
"Ah..."
Lucifer’s mouth fell open as she watched Shaitan’s hands in a daze. Seeing Shaitan’s technique of gripping the testicles then rolling them in her palm, Lucifer’s own hands came to rest politely on her knees.
"I, uh, this is, um...!"
"If you have time to talk, spend it sucking harder."
"Y-Yes!"
Lucifer followed my command and took the shaft back into her mouth. Her movements were far faster and more intense than before; she seemed to be giving 120% of her oral ability.
Glance.
Lucifer kept looking up at me, then stealing glances at Shaitan’s hand, back and forth. The tension in her fingers atop her knees was plain to see.
’Being trapped in the roots meant only her oral skills improved.’
Her hands would have been wrapped up in the root tentacles, so the only thing she could actively practice with was her mouth, apparently.
"Slurp, haahm, gulp, lick."
Of course, I was secretly pleased that a woman who used to react like a stone wall was now being this proactive. I gave Shaitan a look.
"Let’s get started."
"Master, before we begin..."
Shaitan relayed her suggestion to me through the system so Lucifer couldn’t hear. I couldn’t help but be impressed by what she proposed.
"Deal."
Immediate acceptance. A true lord must sometimes embrace his subject’s counsel without reservation. I grabbed Lucifer’s head and stroked it gently.
"Haah..."
"Feels good? Finally getting some reactions out of you."
Lucifer savored my touch while tickling the tip with her tongue. It reminded me of a puppy doing tricks, and I wanted to enjoy it longer, but my shaft was already rock-hard.
"Let’s begin. Flauros, make me a bed."
At my command, Flauros lowered its tentacle branches from the ceiling to the floor and layered them neatly. Onto the instantly formed waterbed, or rather tentacle bed, I picked Lucifer up and tossed her onto it.
"Eek?!"
"It’s nice to see you putting in this much effort. Then I should return the favor in kind."
When I’d listened to Lune’s advice and gone all the way from start to finish, a high-grade magic stone had popped right out. If that was the case, then maybe that was the way to extract a high-grade stone from Lucifer too.
Ras.
Not merely an act driven by the need to relieve sexual desire, but a mutual exchange of love through physical union.
’Lucifer may not love me, but I can at least make her feel like she’s being loved.’
I knelt before Lucifer as she lay on her back, positioning myself in front of her crotch. My reverent demeanor made Lucifer swallow hard and focus entirely on me.
"Tell me if it hurts."
"Ah..."
Creak. Without any warning, I pushed the tip in first. No foreplay was needed. From the moment she’d been pulled from the roots, Lucifer was already slick below.
"Hh, hhnn..."
Lucifer raised one hand to her mouth and bit down on the back of it. She seemed to be holding back her moans, though unlike a certain someone, she didn’t cover her face entirely.
Creak, creak.
Instead, Lucifer answered by clenching tight. Whatever had happened to the back, she’d at least kept Flauros from inserting in the front, so I could feel her inner walls gripping me snugly.
Creak, creak.
Lucifer was working hard, tightening and releasing for my sake. She seemed to be concentrating every sensation in her body into her lower abdomen, trying to figure out how to better stimulate me.
’Something’s missing.’
Effort was effort, and just like the oral where she’d used only her mouth without her hands, something felt lacking. The grip felt like a virgin who’d watched adult videos and practiced with a dildo.
"You seem a bit clumsy...?"
"N-No! I can do this! Inside the roots, I did practice pretty hard..."
"Master."
Shaitan approached from behind and pulled my shaft out with her hand. Her bold move left both me and Lucifer momentarily stunned.
"You’re in the wrong hole."
"What?"
"If you want to enjoy the hole she actually practiced with, you’ll need to go elsewhere."
Shaitan smirked and wrapped her tail around my shaft. Spiraling around it, the shaft swelled as if it had been surgically enhanced.
"Nngh?!"
Shaitan began rubbing the tip with the end of her tail. She was pressing a part that resembled her own mound against my head, creating the illusion that I was grinding against Shaitan’s front.
"The hole to put it in... is here."
"Hiiik?!"
Lucifer screamed at the hole Shaitan’s tail was guiding toward. I looked at the opening Shaitan was teasing with her tail and nodded in admiration.
"Of course. That’s where she practiced the most. I was foolish."
"Hehe, well then..."
"Where do you think you’re going?"
I caught her tail as she tried to unwrap it. Shaitan flinched in surprise but, reading my eyes, smiled and kissed my back.
"Thank you... hehe."
"Stay pressed tight."
"Yes."
Shaitan gripped my shaft firmly so it wouldn’t come loose. The tip of her tail pressed up under the head, propping up the urethra from below. And I placed the combined shaft against Lucifer’s back entrance.
"W-Wait! Something that big..."
"Why wouldn’t it fit?"
"Try to take it in. Make an effort, Lucifer. Heh."
Shaitan and I each grabbed one of Lucifer’s legs. Then I slowly pushed my hips forward.
Squirm, squirm.
"Nnghk?!"
Lucifer threw her head back the moment the tip went in. With both the head and the tail entering together, her walls began to convulse from the very start.
"Nnngh... That’s good. This really does feel like having Shaitan and Lucifer at the same time."
Shaitan’s tail began to undulate in sync with the movement of Lucifer’s walls. The texture clinging to the shaft was Shaitan’s, but the vice-like grip squeezing it belonged to Lucifer.
"Hngh, hhnn, it’s too big...!"
"If it’s big, then put that much more effort into squeezing. Don’t tell me you’re going to reject the love of me and Shaitan?"
"Th-This is love... haaah!"
Shaitan raised her tail and scraped against the walls. Lucifer’s back entrance contracted, squeezing my shaft as if trying to crush it.
"From the very first day you came to our dungeon as a prisoner, I’ve been developing this back hole of yours. How does it feel? The sensation of a back hole that’s never been used for its original purpose? Your little sister and your master coming in together must be thrilling!"
"The, the sensation on the outside is differ... hic!"
"I don’t think so."
Shaitan pinched the inside of Lucifer’s thigh and rested her chin on my shoulder. Pressing her lips to my cheek, she mocked Lucifer.
"Thanks to becoming one with Master... my tail has taken on the exact same shape as Master’s. It’s simply become a ’bigger’ version of Master’s."
"Ah yes, this is what they call enhancement."
Sex magic, how great thou art. All hail the succubus. Though it was wrapped in a spiral, Shaitan had achieved an incredible feat.
The part of the tail touching my shaft replicated the sensation of Lucifer’s back entrance, while the part touching Lucifer’s back entrance replicated the sensation of my shaft. Through Shaitan as a mediator, Lucifer and I could feel each other’s sensations even more intensely.
Creak, creak.
"Aahhn, nngh, hhnngh...!"
Lucifer cried even as she concentrated every ounce of focus on her lower abdomen. She was clenching and releasing so relentlessly that her exposed entrance was visibly twitching about once a second.
’She really is trying her hardest.’
Her skill might have been lacking, but the sight of her putting in effort for my sake was admirable.
"Nnh, hhggh...!"
She couldn’t hold back her moans any longer, letting them spill out; her inner and outer folds trembled together as she climaxed again and again, yet she kept clenching her sphincter through it all. That dedication was admirable.
"Haah, hahh."
Above all, those eyes. Her gaze was scattered in every direction, glazed over, but the slight furrow of her brow as she focused on her lower half was unbearably cute.
’I told her to try hard, and she’s really giving it everything.’
Her technique, honed only through toys and tentacles, was nothing but relentless clenching with no variation in pace, but her sheer effort to satisfy me sent a tingling shiver through my balls.
’Here it comes.’
There was no reason to hold back. I abruptly pulled my hips back, then thrust forward hard.
"I’m coming!"
"Ngh, hh, kyaaaaaah?!"
Lucifer finally screamed. The shaft she’d been so desperately craving plunged without warning into her front, which had only been dripping until now; the moment it went in, she came instantly.
Spurt, spurt.
My shaft jerked several times, pouring seed into Lucifer. Her walls, ambushed by the sudden entry, were shocked at first but gradually began to relax as hot semen filled her up.
"Haah, haah..."
Shaitan also quietly withdrew her tail from the back entrance. I pulled out in sync with Shaitan.
Glrp.
White foam seeped out, bubbling along Lucifer’s crotch. I grabbed the tip and pushed the foam back inside.
"That was amazing, Lucifer."
I leaned down and pressed my lips to Lucifer’s lower abdomen. Where the Seal of Pride had once been, a dark kiss mark now remained.
"Haah, haah. I..."
Lucifer smiled through her tears, her voice aching with emotion.
"I, I really squeezed as hard as I could... How, how was I?"
"Delicious. That was a wonderful meal."
"I’m glad you enjoyed it... thank y..."
Thump.
Lucifer lost consciousness on the tentacle bed and passed out. Shaitan and I stared blankly at each other, then reached an agreement with just a glance.
"I’ll take the front."
"I’ll take the back."
Shaitan and I lay down beside the unconscious Lucifer and continued working her with shaft and tail until she woke up.
Ten minutes until a magic stone was produced.
For those ten minutes, Shaitan and I held nothing back, showing Lucifer every last bit of our technique.
Lucifer produced a rainbow-colored magic stone.
