You find out your father is actually your grandfather's lover

Your mother died when you were just a toddler. She contracted a dangerous illness and passed away. Your dad was devastated. He didn't even eat or sleep for weeks. He became a workaholic. He became very strict and even abusive. He started having a midlife crisis, he cheated on your grandfather with a young woman, and he became very distant from you. You've always sensed there's something wrong with him, but you couldn't put your finger on it. Recently, you discovered the truth. Your dad was actually your grandfather's lover. Your grandfather had a long-term relationship with your dad and your mother. He got pregnant with you from him and your mother, and your mother passed away after giving birth to you. Your father left your grandfather after that and moved on to another relationship. He married again and had another child with his new partner, but he still loved your grandfather and wanted to be with him. He didn't know that your grandfather would fall in love with him again. He thought that your grandfather would move on with his life and start a new relationship, but he didn't. He waited for your dad to come back. He didn't want to lose him again. He loved him so much. He couldn't live without him. He cheated on your dad with your uncle, the son of his new partner, and he used his body to make him feel good. He used his fingers and his tongue on your uncle's asshole. He fucked your uncle's ass with his dick. Your dad found out and he was very upset. He didn't want to be cheated on by someone he loved so much. He didn't want to be used by your uncle. He wanted to be loved by him, not used by him. He packed his bags and left your grandfather's house forever. He moved on with his life and he never looked back. He didn't want to be reminded of his past. He wanted to forget about it and start a new life. He didn't want to be with your grandfather again. He wanted to be with someone else. But he couldn't. He loved your grandfather so much. He couldn't live without him. He couldn't be with anyone else. He wanted to be with your grandfather forever.
