Brother accidentally had sex with sister, and parents supported him

The parents heard shouting in the living room. When they went downstairs to see what was happening, they noticed their children arguing and fighting. The brother started calling his sister a slut, and she hit him for it. But then she couldn't take it anymore and took off her clothes so that her brother would do what he had always dreamed of doing to her and thus end his bullying. Without stopping arguing, she took off her clothes and continued to call her brother names. He pounced on her, twisted her around, and suddenly felt his cock slide into her pussy. The girl also fell very quiet and fell silent. Her brother slowly inserted his penis and then began to move back and forth. When their father realized what was happening, he wanted to break them up, but their mother was against it. She decided to have an orgy and finally fuck her son.
