GML-408 - Tokyo 2020 Olympics event. A sexual competition between Japanese men and women representing various countries (blonde, black hair, etc.). Part 3, Rachel (pseudonym).

I don't really understand what they meant by 'sex festival,' but if you think of it as cosplay, it's enjoyable. In that case, they could have just used foreign actors living in Japan at a studio in Japan instead of going overseas. But I enjoyed it, so I think it's worth checking out if your favorite actress is in it.
