Solving the problems with his stepsister

The stepmother is very worried, whenever she sees the girl and the boy are arguing and she wants to have a happy family. She first talks to the boy who tells her he's going to try to get along better with the stepsister. Then she talks to the girl who tells her the same thing. What she doesn't know is that under the covers was the boy with his dick stuck in the stepsister's pussy. Since they discovered that they fuck very well together the relationship improves quite a bit inside the house!
