I open my laptop and find my son has been surfing for porn. Not just any porn. Mommy and son porn, as well as pissing videos. I call him over to tell him off, but he then takes his cock out. I find myself aroused by the sight and offer to give him a foot job, before taking my tits out for him to suck. Then he licks my pussy and brings me to orgasm. Following this he fucks me and cums in my face. Finally, to complete my transformation from prim and proper mom to slut whore, I piss all over him.
