nothing wrong with that.... dad might be wondering why you both are pregnant at the same time.... well if you tell him the father is black for both his daughter and his wife, then daddy might move out and you and mom can both get your workouts together...
Mom and Dad don't need to know that you have had a black man fucking you a lot..... BUT, if you start to have morning sickness and Mom asks what is going on, just tell her you met a wonderfully hung black man...
