You are in the living room with your mommy when you suddenly start to hear a moaning sound from upstairs. Your mommy knows right away that it is your sister and your sister has a boyfriend visiting again without permission. Your mommy is little angry because your sister is not allowed to bring boys into the house. Your mommy wants that you all (she, you and your dad) go to tell right away your sister that she is doing wrong. You go upstairs first and your mom couldn't find your dad anywhere. She also comes to your sister's doorstep and she gets upset by what she sees. He who fucks your sister is not your sister's boyfriend, it is your dad. Your mommy can't believe that it really happens, your dad, her husband fucks his own daughter... "Should I stop that?" your mommy thinks. You go back downstairs, your sister and dad didn't notice you, they are still fucking and you can still hear their voices upstairs. Your mommy is so mad. She needs comfort and she is glad that you are with her right now. She's still so mad that she wants revenge to your dad and she decides to do it with you. If your dad fucks his daughter upstairs, mommy has the right to fucks her own son in downstairs.. You start doing "it" while the fucking-sounds of your dad and sister are heard from upstairs. That might make your mom even more horny...
