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.

@BookmarkKing
This FC2 PPV leak is going into my permanent bookmarks, very rare to find this quality free.
@4KMonitor
On my 4K monitor the video still looks crisp. Not many free FC2 sites actually deliver true UHD.
@AmateurOnly
I only watch amateur FC2 and this domain keeps recommending real couple content instead of studios.
@TagExplorer
Clicking the tags under the video gives me a full category of similar JAV, feels like a curated site.
@ChromeUser
Running in desktop Chrome with uBlock and the player still works perfectly, no weird issues at all.
@BitrateNerd
You can tell the encoding is high bitrate, dark scenes stay sharp. Perfect for home theater setups.
@CategoryDigger
Found this clip through the FC2 category page, nice to see everything grouped by niche and ID.
@RepeatVisitor
Second time watching this scene on this mirror because the playback quality beats the others.
@SmartProxyUser
Even through a cheap proxy this streaming mirror still gives me HD without loading circles.
@VPNTraveller
Streaming from Europe through VPN and still getting full speed. Great for overseas JAV fans.
@TokyoStream
Watched from Tokyo on 5G, FC2 stream is super smooth and the Japanese subtitles are perfectly readable.
@TrafficGuy
Came from another mirror on this network and the tracking still keeps the video fast.
@4KHunter
Love that this JAV clip is real 4K, not fake upscale. Bitrate looks way higher than other free sites.
@SmartShuffle
Related videos actually match my taste, not random Western content mixed with Japanese.
@EdgeViewer
On Microsoft Edge for Windows 11 and everything runs smooth at 1080p with no stutter.
