You walk in on your sister packing for her vacation. You have something important to ask her. You want to know if she would cover herself up for when your girlfriend comes over. You are worried your new girlfriend will be embarrassed at the sight of your sister naked. She is a nudist after all, and you get teased by your mates about it often enough! Your sister tells you to get a new girlfriend if you don't think she'll be accepting, and then the conversation takes a different turn when your sister wonders why you've never tried becoming a nudist. She convinces you to get naked, and you decide you like the feeling of being so free. You didn't plan on getting an erection, but your sister puts it down to the fact you must be feeling so liberated you have no control... but then she hugs you. You are hugging your sister and you are both naked... Your hard cock rubbing against her bare skin. Soon you are both admitting feelings that you have been hiding from each other, and she takes you in her hand, massaging your length, and then on her knees with her tongue out. She sweetly asks you if you would lick her pussy and make her cum... who are you to refuse! After she cums in your mouth, she straddles you and fucks you until you cum deep inside of her. She laughs at the thought of her mom seeing the cum dripping down her leg, because after all, she doesn't exactly wear panties.
