Ariel Demure, Emma Rose, Cassidy Cauley, and Kasey Kei are all enjoying a nice jog in the park when mysterious green flakes rain down upon them briefly. They think nothing of the flakes as they brush the flakes aside and continue on their jog before all going their separate ways. When Ariel returns home and chats with her husband, Dom Cruise, it's revealed that friends of theirs, Emma and Sage Roux, are trying for a family. That's when Ariel and Dom decide that it's time to try for a family of their own, too. They make love, with Dom delivering a nice creampie in Ariel's pussy. Now all they can do is hope. But the next morning, Ariel's in for the shock of a lifetime as she discovers that her pussy has been replaced with a cock! Ariel isn't the only one. It's soon revealed that Emma, Cassidy, and Kasey have all also spontaneously sprouted dicks overnight. Through the initial panic, they decide that since Emma is going to a gyno that day for fertility tests, maybe the gyno will have some insight into what's going on.
