(This was originally filmed as a custom and is a sequel to Filthy Sister Ass To Mouth) Since you fucked your sister's ass a few months ago your relationship has improved drastically - now your sister can't get enough of you! On your birthday she confesses she has something special in mind for your present - she's going to let you fuck her pussy raw and cum inside her, risking an incestuous pregnancy! As you fuck her she lets out a constant stream of dirty talk, encouraging you to fill her with as much cum as possible and confessing that all her friends have started fucking their brothers as well, and some of them are even pregnant with their brothers' seed! She got jealous and just knew that she had to have you impregnate her, so she's planning to have you cum in her pussy all of your birthday week, draining your balls each day so she's sure to get pregnant! After you've cum once she tells you not to go anywhere, she wants as many loads from you as possible today! She gets filthier and filthier with her talk, drawing out all of the cum from your balls, and finally confessing that she hopes she gets pregnant with a girl so that when it's old enough they can both serve you! After you've shot 3 loads into her pussy she thanks you and reminds you that you'll be doing this all week! Happy birthday little brother!
