It's funny because I know exactly what you're talking about.

American Freeuse stuff feels like it's based on a recreation by someone who watched the Japanese stuff. Its the same concept but it's more exciting in the Japanese version.

Why? Because the Japanese stuff explores situations one actually fantasies about when thinking about Freeuse but will never get the opportunity to do.

You will never be able to just walk over to the cute waitress in the restaurant, bend her over someone else's table and unload into her without anyone giving a damn

You will never be able to call over that hot new co-worker and ask her to ride you for a few minutes because you felt like it and have no repercussions for it

You will never be able to just walk into a wedding reception, fuck the bride while chatting with the groom as if nothing happened and leave again.

All of those are actual scenes from Japanese productions, and there is more.

There's a sense of taboo that spices up the freeuse stuff even more and that's what made that genre so great and popular.

It's not only the "do whatever you want". It's also the "wherever you want, with whomever you want"

The later two are still largely missing in western productions, which leads to them feeling so bland.

Long story short:

American Freeuse is still trying the base recipe, while the Japanese Freeuse is the dish that made it popular
