In most lesbian porn movies that do the formula of having the step-mom and her step-daughter the step mother is portrayed as the agressor, or the one who seduces the younger step-daughter.

It is the logical way to go, but occasionally some movies mix it up and do the opposite, and there is something about seeing a younger girl seducing an older woman that is so much more fun, and hot, to watch.

So thought I would share links to a few such videos with you guys and girls.

That was the ones I could find in the short time I spent looking. Came up with this blog post on the fly so haven't done nearly enough "research". Let me know if you guys know of any others like that.
