You sneaked into your step-sister's room and found a ton of money in cash! There is no way she got all that money unless she has been doing some form of sex work. You confront her and she admits that yes, she has been working as an escort. Wow, what kind of obsessed step-brother goes around snooping like you! Can you afford to pay and become her client? She doubts it. You are very surprised that she managed to make so much money in such a short time, how is that possible? Well, her secret is that she caters to a very specific kink: her sugar daddies love it when she wears very expensive classy lingerie and then doesn't shower and they get to smell her dirty asshole and jerk off. You want to try doing that too, don't you? She has a deal to offer: she will let you sniff her dirty asshole and give you JOI and in return, you won't tell anyone about her secret. Are you ready to start?
