The woman on the cover of R?schen & M?schen 3 is Bianca Deville, who doesn't seem to be listed here. She also appears in Junge Knospen 4, another Tino title.
She was active from about 2001 to 2005. I've seen several other videos of her where she does M/F hardcore and some lesbian scenes but I don't know the names of those movies.
She also had a website for a while.
Here's an archived version of her website as proof:
