*Use of taboo trigger word* You have recently been catching and peeping on your step-daughter masturbating, moaning your name, begging you to cum in her, to impregnate your own step-daughter. On her birthday, you wake her up to be the first to celebrate with her. You tell her you have a big surprise for her, and when she asks what it is, you tell her that you know what she's been doing behind closed doors. At first she is embarrassed and upset, but you tell her that it's okay, that you want her too. For her birthday this year, you want to give her everything she has ever fantasized about with you, even though it's fucked up and wrong. You want to impregnate her, to fill her fertile womb up with what made her. She is more than excited, as she starts to suck you off. She can't believe this is actually happening! She lays back, and you take your own step-daughter for the first time. Fucking her, as she begs for you to take her little taboo pussy, you use your own step-daughter, turning her fertile pussy into your own cum bucket. She loves it, and of course she wants more, forever and ever. Later that day, you give her another surprise: some sexy lingerie. She tries it on for you, mounting you and grinding on her step-Daddy's lap. She tells you that she wants to make sure she got pregnant, that she wants you to breed her again. She pulls your cock out, riding her own step-Daddy, grinding her taboo pussy all over your cock. You cum inside of her again, filling her with joy of the possibility of step-Daddy getting her pregnant. That evening, as she is blowing out her birthday candle, she tells you she wants you again, she wants you to breed her again for her birthday. That's all she wants, that is her only wish. She wants to get pregnant by her own step-Daddy, her own flesh. You fuck her again in doggy and missionary, finishing deep inside of her fertile pussy. She couldn't be more thrilled, as you gave your own step-daughter the best birthday she could have ever asked for, a birthday with step-Daddy deep inside of her taboo womb...
