What a good introduction to the girlfriend's parents. Although the stepmother is not her own mother. Still, she also decided to do her part in raising her stepson. The method she chose, it is true, is not the most popular - I have sex education. But I think it's a pretty brave decision. Considering that she is not his own mother, it cannot be considered incest; on the other hand, for this lady's husband, it cannot be called treason. Since it is his own son. Everybody wins!
The young ones were hiding from their mother as best they could, but she caught them having sex. When she saw the guy's dick, she immediately spread her legs and took it into her pussy. The guy was pleased too, at the end to get such a blowjob, with two mouths.
