Filmed my nude slutty stepsis cleaning up in our shared bathtub

I want to stick my rock hard cock in my stepsister's shaved pussy but I'm not sure she'd let me. I settle for filming her nude in the bathtub and will jerk off to the footage in my room. I'm generous about it and you can also watch and masturbate to her small tits, the view of her shaved pussy, and nice athletic body.
