I walk in on you while you're jerking off to some naughty photos... It's an awkward situation but I take the opportunity to talk to you about how I've noticed that you stare at step-Mommy's boobies. I want you to realize how wrong that is but instead you jokingly suggest that I show them to you. Just as an experiment I massage them with my bra on... Trying to make a point about how fucked up that is, but it turns you on and I notice your dick is hard. I get curious as to why I turn you on, after all I am the woman that raised you. I take my titties out just to see what happens, but after feeling how huge your cock is I ask you to show me . When I see it, I can't resist and rub your dick as I play with my titties. I wonder if you would like your cock in between them, and rub lube all over them. You fuck step-mommy's wet boobies until you cum all over them. We both know this is wrong, but agree to keep it a secret...
