It's what you were born for.

And just like that you understand your future.

The realisation of what you will become finishes you off, your mind becoming a white void as you answer your Daddy with a long, moaning scream. Your blood feels like crackling static and you lose all control of your body, your limbs shivering in pleasure as Daddy holds you down and continues to plunge in and out of you. If someone had told you yesterday that you that being knocked up by your Daddy would make you orgasm you likely wouldn't have believed them, but now as you writhe and cum against your Daddy you know the truth.

Your future was never to be in your hands. From before you were even conceived Daddy owned and controlled your future. You were a big-boobed bimbo because it was what Daddy wanted you to be, and he would reshape your body, your very life, again by knocking you up. You would carry a little sister/daughter inside you, you would love her and care for her all the while knowing her life and future would also belong to Daddy. And you knew you would love every moment of it. That just like your mummy you would love and obey him, live your life for him, be and do whatever he wanted.

"Good girl!" Daddy praises as your legs try to weakly cling to him. You want to feel close to him now more than ever. Your Daddy, your husband to be, the man who would father your child. "You're going to be such a good wife for me aren't you?"

"Y-yes Daddy!" you gasp back.

"And devoted daughter."

"Yes Daddy!" you can't raise your voice, it takes everything to quietly gasp back.

"And a loving mother."

"Yes Daddy!" But at least you don't have to think about your answers. Everything Daddy says should be met with a 'yes'.

He doesn't say anything for a few moments, merely grunting and straining as he pounds harder and harder into you. Instinctively you realise what is coming. He's getting close and soon will unleash his first effort to have you conceive. You can't think but you can feel, and you feel hot, and shaky, and that electric feeling is coming back...and you scream, you scream and moan as you cum again, your Daddy growling as he erupts inside you, his grip tightening and forcing you down even more. The desk is hard against your soft skin but you don't care. If Daddy wants to hurt you he can hurt you, he can demand anything of you now and you'll give it to him gladly.

As Daddy comes down from the high of his ejaculation he lifts his hand from your neck and strokes it down your back, making you shiver as he trails his fingers across sensitive skin.

"That was just the first load kiddo," he tells you, idly stroking your flesh as you purr, enjoying the affection and attention from the only man who matters. "It's going to be a lot of work to make sure you're pregnant."

"Hmmm...Yes Daddy," you sigh back, you don't know if you'll ever need other words again.

Gently he pulls out of you, and you pine at the loss of him but coo in pleasure as he kisses his way up your back, your neck, and then seizing your lips again. The kiss feels even better after two orgasms.

"Let's go tell mummy the good news."
