Clenching And Walking Custom 1

Description: I really want to go on a trip with my boyfriend, but i need money! my stepbrother convinces me to show off my butt and clench it for him, then walk on my walking pad in different outfits. i laugh at him and call him a weirdo for wanting to jerk off to his stepsister's big pale dump truck! at the end i oil up my butt and i know he wants to cum, but i tell him his time is up and he needs to pay me! but he wants me to do one more thing for him: film a gooning video for him. i reluctantly agree and make him promise that he'll pay me as soon as i give it to him.
