This was a LOVELY read!
I wish we had more isekai hentai OVAs that could do this!
A much better way to win that beating her up.
Now we need a Part 2 with a nice harem of inhuman girls.
AMAZING job, darknight!

If you're gonna bring your fucking cellphone with you into the isekai, this is probably the best way to use it...
So yeah, I know what I'm bringing with me after I get hit by a truck.

I like Isekai, but this is just like the rest.
Power play where the female is weak and can do nothing but orgasm time after time again.
How boring.

I think I can guess what happens next.

Base +7, Fofotron +6, SSBDeft +6, MechWarriorNY +9

I could've sworn there was an Isekai story involving an mc with an overpowered smartphone...
Is this reference to that story, only hentaified?
Last page demands a sequel...

In the end, he is the real Demon Lord. I want a sequel dammit!

Base +6, Fofotron +6

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO that can't be the end NTR the King

Base +6, sabitsuki -6, PsychoKingJP +5, reggmail +6, Patch_ -6

This smartphone mind control stories are so good early on when the antagonist is just messing around with her, but always drop the ball latter on. Just going "boop, you wanna fuck now" is so boring. It's a little better here, the resistance is nice, but still, meh.
And please, tag mind break when it exists. It's right there, man.

Is this "Isekai wa Smartphone to Tomo ni" 18+ Version ?

Base +6

How nice of the devs to implement useful features like "Desire" and "Reproductive urges" for my immersion.
Judging by the way he increases them by 10 times every time, they probably made the sliders in logarithmic scale too.
Mad props to these mad cunts.

Base +7, Fofotron +6, abrickhouse +6, Gentleman Chimera +8, Soldier A +6, Scarlet99 +6, mrttao +23, Sadinotna +7

Uses the phone to give himself a big dick, still has to use the phone to crank a girl's sensitivity up to the point where a gentle breeze would probably be enough to do the job and make her so horny basically anything would do in the first place. Idiot should probably consider using his phone to give himself some skill.

But, what about when his phone dies?

Sasuga

Base +6, Zeratoth +6, Gentleman Chimera +8, Soldier A +6, Fofotron +6, Toramaru22 +6, mrttao +23, Ficfactor +18

where does he recharge a phone in that place

Base +6, Captian Katsura +7, Fofotron +6

Surely there could be a second part where he screwes princess and queen, and then later Demon Lord get's in on the action too?

Base +6, Fofotron +6, Zorlond +6

This is my kinda isekai

Base +7

Page 3:
"I mean where I'm from I'm considered average height"

So he's from Japan? ( ͡° ͜ʖ ͡°) ... (downvoted to oblivion by all the guys with Napoleon Complexes)

@ hjerry: Looks more like he goes down the bad guy road with the Queen and the Princess.

Base +6

Eh, those kind of stories are too boring tho. No challenge at all. Might as well get mind control instead.

Base +5, PenisMen +6, Ahegaosensei -5, Gentleman Chimera -8, Isem +4

Thaaaaaaaanks a lot !
Cool storyline and good drawings !

BTW the wordplay considering the

"REAL LAST DUNGEON"

was rather well chosen, I think ^^

Base +6, Gentleman Chimera +8

need more isekai doujins!

Base +6, fuckknuckles -7, xburner337 -6, itachixmaster +8, pr0ninja +7

Kousukes a fucking BASTARD, he did the same thing in the other demon lord doujin where he setup this cute gal for fucking and then never continued it

I just wanna see the continuation of this, please i beg

Base +6, arkshot +6, C4th0de +8, Gentleman Chimera +8

all he mentioned lowering was her Agility so, her Strength should have broken him in half with that leg lock.

Base +6, fuckknuckles +7, Will of the freak +6, Aelth -6

I wanna see something like this where the victim manages to get the device and turn the tables.

Base +9, Gentleman Chimera -8

A true isekai hero.

Base +3

damn, i would love to see princess and queen in action.

Base +7, Gentleman Chimera +8, arkshot +6

She's bleeding when he puts it in on Page 16. Dark "juice" line. She's possibly a virgin.

Base +7, Darksword696 +16

Aw Come on man it was getting started..

Base +1

>amazon demon mind break
thank you lord

Base +7, Aelth +6, zipfizz1 +6, Gentleman Chimera +8

This is remarkably close to some of my own ero story ideas. Could be amazing with a bit better art, but I guess it's fine as it is. I seriously hope the author isn't teasing us with a sequel just to leave us hanging, I'm a big fan of the blonde princess archetype in hentai...

@shadow flux1 you don't think he increased his own stats too?

Base +6, Aelth +6, Gentleman Chimera +8

The app expanded to isekai
Isekai mind control app is my new specific fetish

Base +6

needs a second part very badly. the premise is awesome why not explore it more?

Base +6

Is there going to be a second one with the mother and daughter?

Base +6

This man really setting up another amazing sequel-bait ending he will probably never deliver on?!

Base +6, yoyo10 +15, Gentleman Chimera +8

@darknight Hi, I would like to do russian version for this. Can you give me script and psd files? I would really appreciate it.
