I've gone out on a few dates with a Japanese man, a visiting professor at one of the local colleges. We had talked several times about sexual customs and pornography, and he wondered if I would like to watch some Japanese porn. OK, I'll try something new. It was a little boring to me (not understanding Japanese) and it seemed like the actresses always seemed to be in pain. I guess a lot of Japanese porn is about rape, or at least reluctant sex on the part of the female.
Then there was a scene that he called "paizuru" maybe wrong spelling, but it's what we would call titfucking, or a boob jack. Now, Japanese porn is mostly censored with an electronically created "mosaic" to not show actual penetration, just part of the culture, I guess, but I just broke up laughing at this scene of tit fucking with the mosaic. I mean, everybody knew what was going on, but you could see neither dick nor breasts, which I thought was just silly. What's the point of watching titfucking when you can't see the tits or the cock?
He ended up leaving in a huff because I couldn't keep from laughing. He left the DVD behind, and I watched part of it the next day with the same reaction. I guess in Japan it is OK to be casual about rape and molestation, but showing genitals is a big no-no. Any comments?
