You're away for work and currently on the phone with your wife. She's having some issues with her stove so you asked your brother to check it out... Soon, he arrives and the call between the two of you ends. However, she doesn't actually close the call and neither do you... That's how you end up hearing your wife suck your brother's cock and get fucked by him, saying she wishes she married him instead and how much she likes his cock better.
