Sophie had settled down in the same neighbourhood as her parents. This made it easy to find babysitters. Also, she could regularly go over to her mother and help doing the dishes, while they dished about the neighbours.
It was one of these weekday afternoon dish dates, but her mother was running late. So she had locked herself into her parents house, and started boiling water for coffee.
Standing in the kitchen, she heard the front door open. She immediately recognized the heavy steps of her father and figured she'd have to wait a little while longer. Though he didn't near the kitchen, she could hear him remove his boots and recline in the sofa.
- Margaret, are you home? he yelled.
Sophie decided to play a little prank, and altered her voice to sound more like her mother.
- Yes, she returned.
- Sounds like you're making coffee. Boy, I could sure go for a cup and a blowjob, though not in that order.
Sophie laughed inside. When he found out, his face was gonna be red. Still mimicking her mother she replied.
- Okay dear, close your eyes.
She calmly went towards the living room, trying not to give it away and ruin the shock. As she entered, she felt a bit of a shock herself though. Her dad had already dropped his pants. He was sitting in the sofa, with his head tilted back, eyes closed, and his rock hard cock in front of him.
Now Sophie was really gonna embarrass him. She wasn't going to let him open his eyes, until she was sitting in front of him.
- Was it going to far? She pondered for a moment.
- No, he was always a prankster, and this one would make them even for hundreds of pranks from her childhood.
So she silently walked over and kneeled before her fathers erection.
She was just about to tell him to open his eyes, when something unexpected happened. Her father put his hands behind her head and gently guided her mouth down on his cock.
- Oh yes Margaret! That's just what I needed after the day I had. Her father moaned, still thinking it was her mothers mouth on his penis.
Sophie didn't know what to do. If she revealed herself now, it wouldn't simply embarrass him, it could crush him. She couldn't risk the relationship with her dad like that.
