You and Step-Mom live in a very unique community. A community where taboo couples are the norm. A community where there is a breeding cycle - the Step-Son impregnates their Step-Mother creating a Step-Daughter/Step-Sister for them to breed again when they come of age.
Step-Mom has been looking forward to this day for a very long time, and finally the day has come. Step-Mom is ovulating today and you will be the one to give her a Step-Daughter to keep the traditions of this taboo community alive. Step-Mommy knows just what to say to you so that you have the biggest load of cum for her yet, her greedy cunt is desperate for that seed.
