A teenage girl, Riley Anne, returns home from school, feeling a bit bummed out. She meets her step-mother, Serene Siren, in the kitchen, and they exchange pleasantries. It's clear from their affectionate interactions that they are close, and Serene can tell something is bothering Riley. Although it takes some probing, it's revealed that Riley has a sexist teacher for home ec, who insisted that the students learn how to cook for their future husbands.Serene is livid, gushing about how amazing it is that women are so independent today. They don't need any man, and they certainly don't need to cook for one! Plus, what if some of the girls are lesbians? Or pansexuals? Or polyamorous?Riley tries to stop the rant but there's little she can do. Even so, she admires the fire her step-mother has. She wishes she was as strong as she was, though Serene assures her that one day they will be. Riley soon becomes aroused from having witnessed her mother's passion, though she tries to keep it hidden. Again, nothing escapes Serene's sharp gaze. Her eyes light up as she grins broadly -- is Riley HORNY?? Surely she knows how to masturbate to take care of herself, right?Riley blushes. She admits that she's not even sure if she's doing it right, since it's not doing anything for her. Serene is stunned, deciding that she will absolutely NOT send her step-daughter out into the world needing to rely on others for her own pleasure!Despite Riley's embarrassment and reluctance, she soon can't help but to give into her curiosity. Serene happily leads her to the bedroom and shows her how to properly masturbate. With both of them so turned on, Serene gives Riley a hands on lesson, rubbing and pleasing her sweet pussy. They decide to go all the way to take the edge off for Riley, with Riley experiencing fingerbanging, tonguing, and tribbing like she's never experienced before!
