You are so very close and want to be just like your Step-Mommy-Domme and when she comes to you to tell you that you've been chosen to breed and carry a sissy step-daughter for her, you know you must do your best for step-Mommy. Dommy will be by your side every step of the way warming up your sissy pussy for Bull step-Daddy's taboo fertile seed and getting your womb ready to carry. You belong to step-Mommy and I am only sharing you with step-Daddy for the purpose of creating your new little step-sister. After Dommy pops your cherry, you are placed on all fours facing step-Mommy for the breeding with her firm but gentle guidance.
