Keenan pressed a relationship button and the remote read "Girlfriend and Boyfriend" she pressed the right button and it cycled changing to "Boyfriend and Girlfriend" and then "Daughter and Father" then "Son and Mother" she was about to press that and then remembered that the first relationship was "Girlfriend and Boyfriend" and she guessed that she would be a little boy in that case and continued to scroll through and then saw "Mother and Baby (female)" she shrugged and thought "good enough" and then pressed the button. her body tingled as she grew older and older till she became 30, her breasts were B-cups and she had some nice hips on her now. Then came in the pregnancy effects and her breasts swelled with milk all the way to C-cups and her hips grew further. She didn't see it but some stretch marks also did appear.
You on the other hand had a very different experience. You shrunk and shrunk and undeveloped till you were a bawling baby with a few tufts of hair on your head. Then a bunch of little changes happened making you more feminine. Your voice became more high pitch, your face changed to be more feminine, and your baby dick shrank into you. you didn't notice you were female at the momment, you just noticed that you were very small and very young.
Keenan saw you and picked you up and then swung you in her arms and said "Hush Hush, quite little one..." You then quieted enough for your DNA to change to reflect Keenan being your mother. She pressed you to one of her breasts and you sucked at her nipples for milk. It just felt natural. Keenan picked up the remote and then accidentally hit a button which was.
