uhm what do you mean by color and cultural aspect ?
Hot potato... I wrote something going nowhere and everywhere... then deleted it... Then I see Miri Mizuki's twitter pic and I say... yeah ... that's "cultural aspect" right there... Let me try to re-write some of what I deleted.
"color" is just simply "race" or everything that's visible. Skin color, height weight, hair, nose, cock etc, and big booty (for ladies). The cultural aspect well there's so much. Japan is an island nation, they don't come in contact with the outside world as much. It's just geography.
A IR vid is necessarily also intercultural intercourse, but it's a huge missed opportunity, for making some lost-in-translation or cultural gap moment. For example, (according to JAV) Japanese men enjoy having their nipples played with by the female, whereas in most other cultures, man's erogenous zones are very limited, to basically mouth (+ lips and tongue), penis (+ testises). Beyond that, submissive/bi men may have their anus involved, and only after that, as a very small fringe minority, nipple play. So how should that play out in a JAV IR vid? The Japanese girl start flicking pinching kissing licking and sucking the black guy's nipples, and at first he may be saying "oh, alright... guess you like that" but as the girl keep doing that, he might say "what's going on here, why do you keep doing that?" then their may be a conversation (thru off-screen translator?) and some adjustment.
Like the picture... bringing a big black dude with a red sports car to a nice island location (license plate says Okinawa), yeah looking glamorous right. So what's the black dude wearing? "SECURITY", ruins the setting. So what is he? A nameless, personality-less bouncer hired off the last Justin Bieber concert in Yokohama. Probably for most Japanese people, the only black people they get to
Close Encounter are wearing "SECURITY" T-shirt at concerts and "American" discos and nightclubs.
And his job is what? Keep the rowdy crowd of party-goers from overrunning the barren hill?? And the position he's standing, the way he's facing. For a guy with beautiful physique (as far as I could see) he's put in an awkward position (relation) in the pic. A big black dude, but uncomfortable, unconfident, apprehensive. Probably he and Miri Mizuki never have a conversation beyond greetings.
JAV producers don't understand "black" at all.
Which is why I'm not into IR, the JAV producers only care about the meat (and often can't even procure a well-endowed black dude) and color (in case the meat was disappointing, all's left is the color) but never is able to bring in the culture aspect, like having the black dude (with the Japanese actress) rap or dance or just simply talk.
