Step sister seeks solace from step brother's intimacy

Our young 18-year-old cutie has a bit of a complicated family situation. Her stepbrothers are always trying to get fresh with her, and it's making her pretty uncomfortable. She's not really into their kind of "fun," if you catch my drift. So, when one of them tries to get a little too close, she decides to take a break and go hang out with her friend. But the friend's dad, a pretty big guy, doesn't really like her being there alone with his son. He's got a bit of a thing for her, and he's not afraid to show it. So, when she's not looking, he starts to feel her up. She's not really into it, but she's not exactly stopping him either. It's a bit weird, but it's also kind of hot. They end up getting it on, with her riding him doggy style and then from the front. It's not exactly what she was hoping for, but I guess it's better than nothing.
