Your Step-sister Katherine welcomes you home. You and Katherine have been in a relationship for a long time, even though you are Step-siblings. It is even more naughty, because you guys had raw sex, and now you have a Step-son together. You share a life together, and even though it is wrong because she is your little Step-sister, you are a Step-family unit now. Katherine is feeling the love tonight, and she explains to you she wants to expand the Step-family. She wants to get pregnant again. You are overjoyed! Your Step-sister wants to be pregnant again with your baby and you can’t wait. She starts removing her clothes, and your cock immediately throbs with anticipation. She plays with her big tits to tease you even further. Katherine dirty talks before climbing on top to ride you. Her big bouncy breasts are in your face, and soon they will be filled with milk as well. You resist the urge to cum, you want this intimacy with your Step-sister to last a while. She takes her time, sliding her wet pink pussy up and down on your shaft. She lays back, and lets you thrust inside of her missionary style. Her titties bounce as you pound into her. You are so excited to make another baby with her. She begs and begs for you to knock her up. Once you can’t hold back anymore you fill her up with your warm cum. She is fertile today, so you are both really hopeful you will have a new addition to the Step-family soon.
