*use of taboo trigger word* You have your girlfriend coming over tonight, and you need your sister's help. She quickly figures out it's a sex related thing, and she tells you to ask one of your buddies or something, but you need help with head. You've never given head, and you don't know what to do. Your sister is angry that you've fucked but never given head, saying it's selfish, but then grabs an apple to try and demonstrate. She wants to help, but it needs a bit of a hands on method to figure out exactly what to do. At first she just shows you, but as she works herself up and you get hard, you both start rubbing each other. Eventually, she tells you to practice head on her, that your girlfriend doesn't have to know it isn't your first time. You oblidge, eating your sister's wet cunt until she cums on her brother's face. She returns the favor by sucking you off, filling her mouth with your cum by the end. You're such a good brother, little bro.
