That's the kind of slutty sister every brother would let work his testicles. And this one probably accustomed her to these pranks a long time ago. At least that's what I would have done. She'd have to suck and spread her legs anyway, so why not with her own man? It's about time she got her ass printed, too, so she can date like a grown-up bitch. Or maybe she's still trying to keep her anal virginity for her husband.
What an ill-mannered daughter, how dare she behave like that in front of her father! No wonder he decided to punish her and pull her on his dick. It's worth giving this girl credit - both her figure and face are beautiful, but her behavior and character, there's a problem with that. Her father should punish her more often.
