Becky, my darling wife, I have something to tell you that is very exciting. You might want to sit down for this. It concerns our daughter Gena. I'm proud of how she's grown, learning so much from both of us about how to live. She's always been so kind and sweet, but there have been real changes since she graduated high school. That was about when you taught her the truly important life lessons about what she was meant for and how to be truly happy. She's always gotten good grades, absorbing knowledge and wisdom like a sponge, and your lessons were no exception. She's always been my angel, but with your guidance, she's blossomed into the absolutely most perfect daughter I could ever imagine. I've never seen her so proud, and I've never been more proud of her. She's been spreading the news all day, bragging about what she's accomplished to anyone who will listen. She did what most girls only dream of: she got pregnant by her father!
You knew it would happen eventually. We had been roleplaying daddy/daughter incest since we first met, keeping our taboo play secret from everyone else, with you calling me Daddy when nobody else was around. You had always gotten wet when I started talking about how I'd someday fill any college-aged daughters up with my cum. You knew you'd someday be eating my cum out of our knocked-up daughter-cunt. Reminding you of that always made you tighten around me.
Then, the magical day came when Gena hit her 18th birthday, and she could finally learn the secrets to happiness. You stopped our normal roleplay, and you started pretending to be her because you loved how it made me fuck you harder. You wanted our taboo fantasy to become reality. In the past, you were always so quiet during sex, especially when we weren't alone in the house, but then something changed, and your moans got louder than ever. You wanted her to hear your screams of incestuous ecstasy. You were teaching her. Then you started leaving the door open so she could look inside.
She learned. First, we kissed for longer than most daddies and daughters do, and in a more romantic way. She rapidly progressed, welcoming her daddy's hands all over her body, then later demanding it, not with words but by pressing herself against me and wearing more and more enticing clothes.
You started blowing me in front of her, putting on display the true pleasure a woman can feel when worshipping the cock of a man she truly loves and cares for. Her mouth watered when she felt the bulge she caused press into her, and soon she practically dragged me to her room to begin her daily practice of licking and sucking the cock that made her. She enthusiastically gulped my seed but wanted to become not just better but the best little girl a daddy ever had.
It was also in her bed that she took me inside her for the first time. She loves feeling the cock she devoted herself to thrust inside her. Like her mother, she soon started leaving the door open a crack. Then just in case you walked by, you would see your little girl's smoothly shaved pussy bouncing happily on your husband's cock.
