MOST HARDCORE HENTAI YOU HAVE EVER SEEN?

Nope, the link works. It's just that you're still lacking experience in this area of expertise.

Depends what hardcore means. Disturbing hentai, as in gore, scat, body modification and mutilation, would definetly be Shitai wo Arau and bondage game for me.
Sexually hardcore with extreme penetrations and ahegao expressions etc would be mahou shoujo erena first, followed by Kuroinu and Taimanin Asagi probably. More a fan of the later genre myself..

[color=#9D0A0A]ANYTHING BUT SCAT! I despise that genre.[/color]

[color=#9D0A0A]I was too lazy to use my skills. There is no href link attached to that button. Not sure what that means here but I guess I got trolled.[/color]

Noep. You can ask most elders here about that link, and I'm pretty sure 90~95% of them would say there's nothing wrong with the link.

[color=#9D0A0A]Excuse me Mr. zeroniv_legend a.k.a. ELDER. I demand you telling me what is up with that link. I ain't gonna waste my time searching the internet for some broken/working Spoiler button since I can get the info from you, if you are willing to tell me.[/color]

Or you can use google.

It works fine, there's just special swag you have to do to be able to see it.

idungeddit. all i see is a sad panda being sad.

Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru. Please make your own thread here the next time you want to make a request.

Night Shift Nurse: Nanase Ren

Hmm, I really liked Lover-in-Law, even the dubbed was good. And G-Spot Express had well designed characters and the sex scenes looked so hot. Definitely worth checking out.

There's also Resort Boin and Akina to Onsen de H Shiyo! which I really enjoyed.

When did bible black get kicked under the carpet? Too mainstream?
Well then the most hardcore hentai I saw was BRB. Gonna find the title.

Actually. I'll just go ahead and say Euphoria.

Hmm..its funny how that one was in my mind. My favorite by far is pisu hame.
But for the woah factor I'll go with Kage.

Well, since this got bumped...
Either:

Night Shift Nurses
Dark Love
Euphoria
Pigeon Blood

One of those 4, can't pick.

Taimanin Asagi & Dark Love

This thread could be renamed to "What's the most extreme Murakami Teruaki title you have seen?" and 95% of the replies wouldn't seem out of place.
