My Dad Had an Accident and Now I Have to Marry Him

My dad's accident left him with brain trauma, and his care fell to me. But Dad needed more than the usual care, and his symptoms included an obsession with me and a perpetual hard-on. When his friend, a judge, came by and said I have to marry him, I realized that I have no choice. Dad needed me to be his caretaker, and wanted to get me pregnant, and as his daughter, and now his wife, it was my duty to do so.
