The party's coming up in just a few hours, and I've worked so hard to get the house ready for you and all your friends! I don't want to embarrass you, though, so are you sure this isn't too much cleavage? You think so? Without a bra? Noooo look at them they jiggle and bounce way too much in this dress without a bra! It's totally inappropriate for me to be asking my stepson, but are you sure? Wait, you like it? Are you getting hard right now? Do you like your Stepmom's big boobs? It's ok, Sweetie, I'll put them right in your face so you can feel them and suck on my nipples,  and you can stroke that dick for stepmom until you're ready to cum all over them! Oh fuck this is way too much fun, sooo maybe if we have time we can go again before the party!
