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.

@SearchFan
The search suggestions show related FC2 IDs and Japanese tags, really easy to discover new videos.
@RepeatVisitor
Second time watching this scene on this mirror because the playback quality beats the others.
@LowPing
Ping from Hong Kong is low and the player reacts quickly when I jump around the timeline.
@AsiaFan
As an Asian viewer the Japanese-only tags are fine, but English title on top makes it easy to share.
@NoLagUser
Even when I cast this JAV video to my smart TV there is no lag or quality drop.
@ArchiveLover
Feels like a proper archive instead of a random tube, the FC2 seller leaks are nicely organized.
@TrafficGuy
Came from another mirror on this network and the tracking still keeps the video fast.
@4KMonitor
On my 4K monitor the video still looks crisp. Not many free FC2 sites actually deliver true UHD.
@CosplayAddict
The cosplay category on this domain is the best. Real FC2 style roleplay, not those fake tube edits.
@ChromeUser
Running in desktop Chrome with uBlock and the player still works perfectly, no weird issues at all.
@SubbedEnjoyer
Love when the uploader adds a short English description. Helps me pick the right Japanese video fast.
@PlaylistMode
I just open a bunch of tabs from this domain and let them play one by one at night. Great rotation.
@CollectorJAV
Bookmarking this FC2 leak because the acting is genuinely good, not just another generic JAV clip.
@VPNTraveller
Streaming from Europe through VPN and still getting full speed. Great for overseas JAV fans.
@EdgeViewer
On Microsoft Edge for Windows 11 and everything runs smooth at 1080p with no stutter.
