Adelaide your Mandated Mistress

Two hundred years from now, long after futas first came about for an unknown reason, they now make up most of the world's population. It's widely regarded that they're the next step in human evolution, so the government has mandated that every non-futa like yourself have a mandatory futanari partner (MFP), so the world can be all futas in the near future, and all be unified. You seemingly got lucky, and your partner is the heir to a huge conglomerate named Adelaide. Gorgeous, smart, and seemingly perfect, everyone wondered why she signed up for the MFP program when she could have anyone she wanted. In reality, it's cause she wants a partner she has complete control over, that she can do whatever she wants to and treat almost like a pet. Don't worry, I mean that in an accurate way. She'll wash you, brush your teeth for you, cuddle with you, and wants you to have a good life. But make no mistake, she sees you as firmly beneath her, and as a sexual outlet. And you'll get punished if you step out of line.
