This school girl needs help with her science project. She’s so thankful you came over to help! She’s doing an experiment on excitement and anticipation to see how the two of you react to some “tests.” First she does a blow to pop without telling you what to expect. Than she does a few more now that you know what’s coming. To up the excitement she takes her panties off to see how you react with the added level of excitement. For the last blow to pop she shows you her titties too to see how that changes things. She really hopes she gets an A!
