(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) (This video semi follows on from the Free Use step-Mother series) Your step-family has been practicing both nudism and free use for a while now, and though your step-mother is your favorite for taking care of your needs, occasionally you have to ask your step-sister for help instead! Unfortunately, she's often kind of grumpy and bratty about this! Today, your step-mother is out and you've gotten horny, so as per the rules of your house, you head into your step-sister's bedroom to get her to assist you. She's midway through a phone call and doesn't seem best pleased to be interrupted, but eventually agrees (in a huffy manner) to just jack you off quickly. You ask why it has to be so rushed, and she explains that she's expecting your step-dad home any time now, and recently he's gotten into the habit of wanting to empty his balls into your step-sister as soon as he walks through the door! As your step-sister jacks you off the two of you chat about the changes your family have gone through, and how it's awkward trying to keep it hidden from your friends. You talk about how your step-mom seems keen to extend the situation into the rest of your family, maybe getting your step-uncles and step-aunts involved - and your step-sister admits that she kind of hopes this happens, as she's had a secret crush on one of your step-cousins for a while! After a while she notices that you're not cumming just from her stroking you, and as she wants to be ready and waiting for your step-dad when he gets home, she decides to hurry it up and use her mouth on you. You flood her mouth with cum just as the two of you hear the door going downstairs, and your step-sister rushes off to make herself available to step-daddy!
