Watching your step mom

Your 18 years old, and lately your new step mum keeps treating you to expensive presents, you wonder how she's paying for them, you wake up late at night one day and hear noises from her room, you peek through her door and see her doing a cam show. You watch for a few minutes as she shows off and strips in front of her laptop. You decide to trick her, the next night you log into the cam website and sure enough shes live, you request to take her private, she asks if there's any particular you want to see and you ask her to do cam to cam, you also ask her to pretend to be your mum. She seems awkward and embarrassed at first but once she sees you pull out your huge dick she succumbs to temptation and really gets into it, explicitly telling you how to get off while showing off and dirty talking. As she gets more excited to see you cum she starts getting more and more into the fantasy, fingering herself to the sight of you jerking off, until she orgasms, accidentally moaning the pet name she always calls you. As you close your laptop in a panic, she heats a noise from your room, she also thinks she glimpses your face, leaving her in confusion and curiosity at what just happened
