Hmmm... I really need to find the *perfect* pair of panties for my date tonight but... none of these are perfect! I wish I had a man's opinion, they always know what looks best. Oh honey, I'm so glad to see you! You actually have some really good timing. See, step-mommy is going on a date tonight and I just can't decide which pair of panties look best. Do you think.... well, would it be too awkward to ask you to help me pick out a pair? I could just show them to you and.... So what do you think? This pair... or this one... or.... honey! What's that in your pants?! Do you have a hard one... for step-mommy's ass? You told me this wasn't going to get weird and it totally just got weird. What are we going to do? Your aunt is going to be here any minute to watch you while I'm gone and she can't see you with a huge erection like that! Ummm.... Well, I guess the only thing I can do is... I'll just have to help you out a little. I mean, I normally wouldn't do this but we really don't have time right now. Look step-son, just pull out your penis and touch it while I show you step-mommy's butt. You obviously like the way it looks in these panties so it shouldn't take you too long to finish. Just don't mess around, your aunt is going to be here any minute and we have to get you finished and cleaned up before she gets here and I go on my date!
