Your step mom Daisy Dax wants to have a chat with you. She's lit and lonely because your father is so much older than her and he's so boring! And they haven't been able to conceive even though Daisy has tried everything! She's pretty sure he's shooting blanks. Daisy knows that she isn't your favorite person since she's the fat slut that married your dad but she needs a favor from you. Will you fuck her and knock her up? She's been wanting to fuck you anyway since she met you, and the bb would look enough like your father that she can pass it off as his. This is so hard for Daisy to ask but she's been thinking about it and this is the only option. It'll be your little secret! All she wants is a bb, please can you fill up her pussy with your seed? She begs you to fuck her and you do, you fuck her hard, sliding in her hot wet cunt with her bent over as she moans and begs you to pound her pussy and cum in her. You flip her over, pull her panties to the side and fuck her more until you cum and Daisy has a full load of your sperm deep up inside her. After you finish Daisy describes how her body is going to change as she becomes big with your spawn. And Daddy never ever needs to know. Daisy thanks you and tells you gratefully how badly she needed a good hard fuck.
