Your step sister wants to go out with her friends, but she needs money. That's here you come in! She asks for some cash, but you refuse, ignoring her and focused on your video game instead. But then you see what she's wearing. Your step sister is dressed like a total slut! She notices that you got a boner, and though it creeps her out a bit, she also sees it as an opportunity. She gives you a deal - she'll give you release if you give her your wallet. You agree, so she gets on her knees and sucks you off, swallows your cum, then leaves with all your money.
