Your step-mothers obsession with you becomes even more intense after she decides to use her goddess powers to make you permanently a part of her. In the first phase you are ingested by her futa cock which has grown large from all the friends and girlfriends she has had to consume, only she can have you. The first insertion feels too intense and she uncontrollably cums you out, but on the second attempt you're pushed slowly down her shaft, successfully settling inside her balls to have your DNA altered. The next morning phase two begins, her cock now having disappeared but you sit within her belly for her final transformation. While you're inside, she swallows both of your folks. They never loved you like she does, and she is consuming with lust having all if you inside of her. On the third day the transformation is complete, you now share her DNA and are officially hers. You feel bonded to her in a way you never did before and the two of you cum together to strengthen your connection.
