John's Dream Girl (chapters 6 through 10)

... can remember. He ate me out too. But God, I used to really 'get off 'on having that big, long dick in my mouth." "Didn't you think that the head on Daddy's dick was kind of weird-looking? I mean, the way that it was all flared-out at the back, and kind of small at the tip." "Yeah, it did have almost an arrowhead shape to it, didn't it? But to me, that just made it even more sexy," Jan admitted. "Weren't you ever worried about Daddy getting you pregnant?" Lisa asked. "Of course I was. Weren't you?" said Jan. "Sure. But that never happened, because Daddy only had sex with me during my 'safe times.'" "During your what?" Jan asked. "You know? During the first and last weeks of my menstrual cycle." "You got lucky, girl! It's a miracle Dad didn't knock you up. I hate to break the news to you, Sis, but the rhythm method isn't that effective at preventing pregnancy. And that's because, every so often, we girls can ovulate twice during the same cycle. And sometimes we can even ovulate during our periods, believe it or not." "Wow! I never realized that," Lisa said, feigning naivety, even though she already did know everything that Jan had just told her about the rhythm method. "So then what you're telling me is that the rhythm method really does work, but that it isn't considered that reliable," Lisa added, still intentionally playing dumb on the subject, just to see where Jan would go with it.

But the bad part was that I didn't know exactly where I was at in my cycle that night--because, to be honest with you, I hadn't been keeping track." "After that first night, Dad would unexpectedly show up in my bedroom late at night to have sex with me. And that would always scare the crap out of me, because even though Dad only had sex with me during my 'safe times'--just like he did with you--I knew that the rhythm method wasn't that reliable. But outwardly, I always did my best to act like nothing was wrong, so that Dad would go ahead and fuck me. "Then one night, my luck finally ran out. I remember that I was feeling unusually horny that night. And I could tell that Dad was too. He fucked me twice that night. And the second time, we ended up 'doing it' doggie style. And right before he came, he shoved his dick deep inside me, and shot his whole wad right up against my cervix. "And just a few minutes after he pulled out of me that second time, my womb started feeling really strange to me, and I sensed that Dad had just gotten me pregnant. Don't ask me how I knew. I just did, that's all. But of course, I didn't say a word to Dad about what I was feeling that night. "About a month after Dad had moved out of the house, I ...
