Your Step-Mom tells you she needs to have a serious talk with you. Well, do you remember that not so long ago she told you that her and your Step-Dad are siblings and you and your Step-Sister are the product of inbreeding. Your Step-Sister is barely legal and just turned 18, its time to expand your genealogy. Your Step-Sister should be impregnated by you, you will be good parents. Your Step-om tells you that she wants you to go into your Step-Sister's room and fuck her till you cum inside her, once you are done your Step-Mom want to smell and taste your Step-Sister's pussy on your cock. You are rock hard from hearing this, your Step-Mom gives you a handjob to prepare you for your Step-Sister (simulation without dildo). You are just like your Step-Mom, being intimite with yours is what turns you on. You go to your Step-Sister's room with your boner, throw her on the bed and fuck her really good. She is kind of hesitant, she doenst want the 2 of you to follow in your parent's footsteps. She gives in to this lifestyle and accepts the fact that she will become a Step-Mother. Once you are done with her, you go to your Step-Mom to have your Step-Sisters creamy pussy juice licked off from your dick. Your Step-Mother swollows your cum and tells you that tomorrow you will be doing the same
