Which mommy makes you cum?

Come on in, stepson, and sit down. Your Stepmom and I have been waiting for you to get home. I don't want you to be alarmed. You aren't in any trouble. It's just that... oh my, this is kind of awkward. Well, stepson, I was using your computer and I noticed... an awful lot of porn. Which is TOTALLY normal for a boy your age. There's absolutely nothing wrong with watching porn! It's just.... the kind of porn that I found on your laptop. Well... I thought maybe your Step-Mom and I should get together and sit down and talk to you about it. When I called and told her, she checked the computer at your old man's house, too. It seems that you're really into Mom/Stepson taboo porn, huh? No need to be embarassed, honey! We're just curious.... which Mommy is it that you're thinking about when you're watching those naughty videos? Both of us? Hmmm? Oh, come on, we kind of think that it's hot. Maybe you could pull that hard cock out for us...
