For a certain fee now any stranger is ready to take off her clothes, spread her legs and suck the first man she meets. Every cute girl is weak in the face when she sees bucks in front of her. I wouldn't want to be a pickup artist because it's a risky business to fuck unknown holes. Sure you can use a condom, but rubber doesn't always save the day.
But she shouldn't have slept naked, then her brother wouldn't have taken pictures of her fur. And now she has to suck his dick so he doesn't post these pictures online. It's a big brother's favorite pastime to get sisters like that to have sex. She doesn't know that he didn't have a smartphone in his hand and he was just jerking off on her. So he gave the girl a free pass. I'd probably do her ass so she wouldn't be so stubborn!
I'd put her tits in my mouth.
