This is a custom vid. You’ve always been obsessed with your stepsister’s huge natural tits. Everyday you wake up with your cock hard as a rock imagining how awesome it would be to fuck those perfect melons. And that day is today! Your stepsister wants to make a deal, she needs your cock to practice a new move for her boyfriend (pussy rubbing). In exchange for lending her your cock, she’ll let you fuck her tits and even cum between them. You don’t need to answer, your hard cock is already telling her all she needs to know. All the dialogues are written.
