My Step-sis Is Begging Me To Put A Baby In Her!

I came home one day to find my step-sister waiting in my room. She and her boyfriend have been trying to get pregnant but it seems like it hasn’t been working. She says she has an idea, but she needs my help to make it work. Whatever it is, I have a feeling he’s not gonna like it, but as long as he never finds out, I don’t really care!
