What is Tsubomi? The second two videos look like some kind of game show where the girl has to make the guy cum in 10 minutes, using the method written on a ping pong ball. It sounds like they said "askoki" or "asikoki" (could be Japanese for bootjob?). If there's anybody who can read Japanese, here's what is shows in the video:
I'd really like to figure out what's in the parentheses. The last two symbols are "koki", but I can't figure out what the first symbol is. If we could figure this out, it would make it a lot easier to search for bootjob videos in JAV and other places. I love Japanese boot porn, but it's still weird to me that they pixelate naughty bits. What do they think they're hiding?
