You go into your stepsisters room to ask her some questions…. She is really really weird… but oddly hot. You worry about her not being a christian… and worse… her worshipping the devil! You go to talk to her about Bible study and she seduces you into fucking her instead. You accidentally cum inside her and breed her! She reveals she is not just your stepsister, she is actually a Succubus! You bred a Succubus. She is pregnant with a half demon half human! You really are going to hell… maybe you like it?
