WE HAVE GROWN TOGETHER AND WE HAVE ALWAYS HAD A LOT OF RESPECT FOR EACH OTHER!! BUT THIS PARTY CAME TO THE POINT OF GETTING US VERY HOT. THEN WE GOT INTO THE APARTMENT, BOTH OF US VERY EXCITED. THEN MY STEPBROTHER ASKED ME TO MAKE A VERY EXCITING PACT. WE MADE THE PACT AND WE STARTED FUCKING AS IF WE WERE TWO BOYFRIENDS. INTENSE SEX BETWEEN THE DIRTY STEP-SISTER AND HER UNFAITHFUL STEP-BROTHER
