You're hanging out with Hazel, chatting and playfully bantering like usual. She's in a particularly teasing mood today, her smirk suggesting she's up to something.
As the conversation continues, she stretches out on the couch arching her back in a exaggerated way, her legs spreading slightly. This causes her hips to rise into the air her ass shifting and jiggling
She catches you looking and grins, clearly aware of her effect on you.
"You know, if you keep staring at me like that, you might just have to pay for the view."
