Surprise mom fucking her boyfriend and decide to join her

What is this mature situation, who has a problem and runs out of glasses, so I don't see three in a donkey. When she gets home, she meets a man and automatically thinks she's her husband, so she kneels down to eat his dick. But in reality, it's the son of his daughter! When her daughter arrives, she finds her mother fucking her boyfriend and is shocked. The mature woman explains what happened and, given how well they are having sex, the best thing to do is to join them so that the fox ends up aiming at her boyfriend to have sex with both of them.
