It's always possible to be turned into a lesbian you know; you don't have to be genetically gay. And the older woman in this lesbian sex scene is the type of woman who can orchestrate it happening. She's the type that gets a couple of innocent hetero babes like this together and convinces them that they can have a much better, more fulfilling experience sexually if they were to fuck each other. Of course the old bird gets to flick the peanut while the two young babes get it on!
