We intercept a pair of siblings while they're out shopping. The sister seems to work in medical administration; she'd probably look good in a lab coat. Under the guise of confirming their sibling bond, we start with their favorite foods and gradually escalate to questions like 'Do you have a boyfriend?' 'Have you kissed someone?' 'Have you masturbated?' For a pair that seems game, we lead them into some dirty talk and then guide them into some frottage. When the brother gives nonsensical answers, she sighs 'Oh brother...' but her responses show she really likes him. So, she's totally into her big bro? Laughs As he gropes his sister's huge tits, his brother gets an erection during frottage and she says 'No no' while wrapping her pussy around him. It doesn't stop at frottage; they end up having sex and he finishes inside her!
