The Japanese site H0230 -- or http://en.h0230.com/index_en.html
-- is mostly solos of "real guys," mainly in their 20s, and some middle-aged professor types.
In each clip, there is quite a bit of talk in Japanese to start, but once they get their clothes off, the camera is not shy, it really explores their bodies, and they all blow a load at the end. The site's few gay sex clips are, to me, less remarkable. They have a few multi-guy peeing clips that I liked quite a bit.
The early clips (numbered "ona0001-ona0300") are lower in resolution. By the 0400s, editing and overall quality are better, mostly 1280x720, if I recall.
Here is one GT thread (not mine) that contains 85 of the H0230 clips, where you could try a few to see if you like them:https://www.gaytorrent.ru/details.php?id=1b7e01fd3f9ff54f0f35bb545598e67154263a29a08bf991&filelist=1#xfilelist
Here on GT, there are also a few single files of the newest clips, 0500-0999. Simply search "H0230."
I would really like to know if anyone has encountered a complete "site rip" for these higher H0230 entries (0500 and up). Surely, they must be the highest quality of all..!
