I Can Help You, But You Have to Fuck Me In Front of Your Wife

I can't believe my stepbrother had the nerve to invite me over and ask me for help in front of his wife, after the type of relationship we used to have. Doesn't his wife know how many times our parents caught us fucking when we were younger? I can see how desperate they are, though, so maybe I can offer a deal where we all get what we want. I'll help them with their situation if he fucks me in front of his wife. I've been craving his cock for ages, and it's the perfect opportunity to show her what kind of man her husband is.
