We're blessed that twins run in our step-family; it's a gift that it doesn't skip a generation like it does for others. We're also cursed. I know that's hard to believe, but you must for the sake of our step-family. Our tradition is the one thing standing between each generation and tragedy befalling them. When step-twins are born, they share a unique bond: two people who came into this world together belong together. You and your step-sister have always been so close. Now that you've both come of age, it's your turn to partake in the step-family tradition. It's a ceremony, a ritual of sorts. You must come together as one. Just as your step-father and I did before you. Don't worry, step-mommy's here to guide you both every step of the way, to ensure the ceremony is completed. Together we will ensure that the curse is broken and the step-family gift is passed on to the next generation. Warning! Features: inbreeding and legacy themes, lots of taboo trigger words, creampies, virtual and dildo sex, losing virginity, blowjobs, doggy, missionary, cowgirl
