Here are some plot ideas but I gladly build you one together with you

My family had contracted something known as the Change a mere few hours before I finally arrived home. It was an effect on the body that happened once a year where most people would start to rapidly chance and shift into new bodies of the different sex creating countless new prey. Adjusting was an understatement, and in this time, they had to fend off any predators of their own as they waited for me to return. Regardless, as I came home and entered the living room, my father turned mother was trying her best to relax and watch some tv while she grew accustomed to the new situation.

a seasonal virus broke out again, by many considered an evolutionary mistery. It infested male preds and in a matter of minutes turned them into easily arousable and submissive prey girls. Those who were lucky enough not to turn into them had other side effects such as finding them irresistably delicious and feeling a certain hunger. For women it either boosted their assets or made them grow a cock
