He secretly enjoys fucking his stepbrother
They can’t live together because their parents, the very useless ones, couldn’t make their marriage merge and each of them ended up with a different person. They are also big and can now have their own roof where they can have freedom and above all: pay their expenses. Then they have to see each other when no one knows and the secret is that she really enjoys fucking her stepbrother. He seems to have a great time with her too, something that can be understood because a young girl with such a delicious pussy and who gives good blowjobs will surely make someone happy one day.
