You thought that step-mummy didn't know that you sometimes sneak by the shower to see her naked? Or that she didn't notice the way you get a hard-on every single time she wears tight clothes around the house? She knows why you quickly go to your bedroom right after and lock yourself in there for a few hours! You've been secretly (or not so secretly) jerking off to your step-mummy, but that's ok...it's understandable, now that you turned 18. All the hormones are probably driving you crazy at this age! Step-mummy has a little secret she wants to share with you, though! Your step-dad hasn't been able to satisfy her much in bed lately, but she has something much better than a cock - a little vibrates that helps her have multiple orgasms! Wanna see? Shhh promise not to tell anyone about this, okay? Step-mum's gonna show exactly how much pleasure a woman can feel with the right kind of stimulation, but you're not allowed to touch - only watch and let your teenage dick get hard - then you can jerk off in your room later on. If you're a good boy, I might even flash you just a little!
