The Mike and Flora sessions with Petter Hegre were likely filmed over a few days in Barcelona where Hegre had his studio at the time.
There is a behind the scenes video of the photo sessions where you can see Flora is not shy about stroking Mike's cock between pictures, keeping him hard for the poses. I'm guessing Hegre's intuitions told him to encourage her to push her boundaries as a model, especially if she was enjoying the experience.
This led to a couple of massage videos that became increasingly explicit. She did seem to draw the line at intercourse, but finger penetration was allowed and of course she performed fellatio on Mike and eventually the ejaculation.
Hegre released this series over the course of a year. As a fan of interracial erotica I found this to be one of the most exciting and anticipated set of IR pics and videos.
Flora has a few other explicit videos with a white male model and Mike has been seen in other massage videos at Hegre.
