Scientist Nagasaki, researching human cloning, was conducting an experiment attempting to enable clones and humans to reproduce through sexual intercourse. The male subject's task was to mate with "Yukine," a clone created using his own DNA. Despite knowing it was a dangerous study, he complied and had sexual intercourse with her. Afterward, the man remained dissatisfied, claiming that "clones and humans have different skin temperatures," and to prove this, he also had sexual intercourse with Nagasaki. This is a record of the experiment involving a clone and a man.

@SmartShuffle

Related videos actually match my taste, not random Western content mixed with Japanese.

@VPNTraveller

Streaming from Europe through VPN and still getting full speed. Great for overseas JAV fans.

@RepeatVisitor

Second time watching this scene on this mirror because the playback quality beats the others.

@NewHere88

First visit to this mirror and I already like it more than the big tube sites. Much less spammy.

@MobileViewer

Viewing on Android Chrome and the mobile player is clean, no lag even when I scrub the timeline.

@MultiTabUser

Opened eight videos from Recommended and they all buffered instantly. This network is seriously fast.

@FC2IdCollector

Finally a place that keeps the original FC2 ID in the title so I can search the seller later.

@PlaylistMode

I just open a bunch of tabs from this domain and let them play one by one at night. Great rotation.

@CosplayAddict

The cosplay category on this domain is the best. Real FC2 style roleplay, not those fake tube edits.

@NightOwl

Late night session and this uncensored Japanese video loaded instantly, zero buffering on my WiFi.

@IndexSurfer

Found this domain on a Chinese SEO tool and decided to click. Glad I did, the FC2 content is insane.

@CleanUI

User interface is dark and minimal, really good for late night viewing without eye strain.

@LowPing

Ping from Hong Kong is low and the player reacts quickly when I jump around the timeline.

@UltraViewer

I watch in full screen on a 34 inch monitor and the picture stays sharp from edge to edge.

@AsiaFan

As an Asian viewer the Japanese-only tags are fine, but English title on top makes it easy to share.
