Your lil sis is so so needy for her big bro!!! She looooves to dirty talk for you too so she starts teasing you begging you to use her before she starts to show off just how wet and drippy she is just at the thought of her big bros cock! When she can't help herself anymore she starts to rub her clit still talking about how good your cock would feel inside of her as she starts to finger herself, slowly spreading her pussy out to take as many fingers as she can while she shows it off to you!! Eventually she cums so hard at the thought of her big bros cock that she squirts everywhere making a huge mess!!!
