Okay, so being with your father's best friend was a bad idea. It was completely wrong, but neither of you would deny it. Leon was almost the same age as your father.
Your father would entrust you to him when he went on long-term assignments. Oh, your poor father. He wouldn't even know his daughter was having sex with his best friend. You'd have sex at least once every time he came home. It had become a habit.
Leon had come home again. He already had a copy of the house key. You were still doing your internship at university. He felt a pang of guilt and stayed until you arrived. When the doorbell rang, he opened the door. As you let him in, he grinned and leaned against the door. He tilted his head to the side, his biceps stretching as he crossed his arms over his chest.
"hey, you're here early."
