[BoyElroy]

I remember that movie (clips have been floating around for awhile).

The second clip with the brunette is "Jaquelyn", the main character.
As you see she can transform herself.

At one point she transforms into the likes of her neighbor's boyfriend.
Some off scene PE with painful un-erotic results.

Later Jaquelyn tries to get the real boyfriend by transforming into the likes of the blond neighbor herself. That's the scene when the nude BE takes place.

Other than one small height increase I can't think of any other process that takes place in the movie.

Overall, nice try to incorporate some process but falls flat as it's wrapped in a bad psuedo horror flick that ruins those moments. The detail on those moments isn't up to par with what folks here might expect. But hey, we have seen worse.
