Your stepmom needed to use your phone and OMG it's full of close-up photos of assholes from many different girls, you even bought asshole porn! Now step-mommy knows that you have an asshole fetish, but don't worry, your secret is safe with her, she won't tell anyone! But she is curious, what about her asshole? Would you be turned on seeing your mom teasing you with her tight asshole, spreading it and instructing you to sniff it, lick it, and explore it with your tongue while stroking your hard cock? Oh btw, she hasn't showered so her asshole will be pretty stinky, are you ready to cum for stepmom?
