Stepsisters oväntade impregnering

Hey, I know we have that agreement... I made you pretty late to practice, so it's only fair that I spend that much of my own time doing something for you. But sex? I don't think that's the answer! Remember last time, we weren't smart and we didn't use protection and we had a pregnancy scare! We can't let that happen again. Mom and Dad would flip their lids! No one can find out and an accidental pregnancy would for sure expose us... But, I'll do it for you if you promise to pull out! It did feel so good last time. Okay... hey! I said pull out, oh my god!
