The Taboo Union

My step-sister and I have been together for as long as I can remember. We took eachother's virginities, and sexually explored with eachother until we were old enough to leave the house. It has been a long road of trying to conceal who we were, masquerading in public as though we are husband and wife (to explain our same last names). We have tried moving, multiple times, but it always seems that we can't escape the stigma of us being together. Today, however, that all is going to change. I was able to finally find an officiator that was willing to marry us. Now we will have the legal cover for why we have the same last names, and can hopefully continue our relationship without all of the negativity we get from the rest of the world. I am so beyond happy, and just as we are about to fuck one last time as just step-brother and step-sister she realizes that she wants this night to be extra special. She wants me to breed her once she is my actual legal wife! So, we rush off to prepare and go tie the knot. Once we get home, we have only one plan for our honeymoon. Lock ourselves in our room and fuck for days on end. Finally, not just step-brother and step-sister but true husband and wife. The only problem is, as I lift her wedding dress up and begin to shove me cock in her, biology picked the most inopportune day. So the impregnating her idea is gone, but we make the best of it. I take her messy pussy hard and rough again and again. In her dress, out of her dress, throughout the night, and the next morning. She cannot wait to be done with this process so her step-brother (NOW her HUSBAND) can breed her FOR REAL.
