Overview:
The protagonist found himself confessed to by his classmate Sakura.

Though he insists "Never!", he grows uneasy realizing he can't even define what counts as cheating. Seeing his turmoil, Toka offers an unexpected solution:
"Why not test the boundaries yourself and decide? If an act feels like cheating to you, then we stop. Simple, right?"
And so, at his childhood friend's insistence, their forbidden "lab experiments" begin...​

Oh wow… so the MC just went from “first girlfriend euphoria” straight into “let’s turn my childhood friend into a personal ethics lab rat.”

 

[xmilteach]

thx

 

[vall6269]

Uhh is it really kinetic? I'm so confused by the description and tags

 

[pentane]

so is the guy cheating on his girlfriend or girlfriend with another guy?

 

[Mr.SpacePenguin]

 

[Imisx]

That's the dumbest plot I've ever read.

 

[X Death]

The ntr content in this game is just 1 scene, mainly you "testing" what is cheating. Also story is kinetic or linier.

thanks for sharing

 

[Arkade]

their monhun-like ntr game should have been the one to get translated. if it isn't already

 

[Dyemeter]

Haha love the plot

Friend A : I'm worried my BF will cheat on me
Friend B : If that worries you, I can make it a certainty!

 

[Febui]

That's the dumbest plot I've ever read.

I saw a plot that was "you got injured after your wedding so you sent your wife to go on your honeymoon without you"

​

Godsdammit, you can't put filth like this uncensored in the first image without even any warning. Pretty sure there's article in Geneva Conventions about that.

 

[YdenMkII]

so is the guy cheating on his girlfriend or girlfriend with another guy?

Mainly it's the guy cheating on the girlfriend with childhood friend but as a twist, it's shown that the girlfriend was only stringing the guy along because of her real boyfriend wanted to fuck her in front of him.

"Why not test the boundaries yourself and decide? If an act feels like cheating to you, then we stop. Simple, right?"

"And so, at his childhood friend's insistence, their forbidden "lab experiments" begin..."

Netori: Female POV Vs Male Protagonist...

but as a twist, it's shown that the girlfriend was only stringing the guy along because of her real boyfriend wanted to fuck her in front of him.

Holy shit, now that's brutal.

Wait, let me process this...

So, Sakura already have a boyfriend and he ask her to confess to MC so he (the boyfriend) can enjoy his fetish of "stealing" someone's girlfriend?

 

[Acropolis]

The art is reminding me of ts:

Yes, and your childhood friend basically makes you cheat on Sakura with her because reasons? idfk.

 

[ffive]

Yes, and your childhood friend basically makes you cheat on Sakura with her because reasons? idfk.

We all know childhood friends are contractually obliged to have hots for the MC.

 

[DarkDaemonX]

Yes, and your childhood friend basically makes you cheat on Sakura with her because reasons? idfk.

Well, that just means the MC will just have a new girlfriend instead, bet that other guy and Sakura didn't see that coming.
