Becky's Reckoning serves as a sequel to the events of Shelly's Future Past, following the journey of Becky, the daughter of Shelly and Triss, as she embarks on a quest for a normal life after helping her mother save Earth from impending doom.
Set on Becky's eighteenth birthday, this narrative unfolds in a richly developed, fully lesbian context, offering players a choice-driven experience with multiple stories and love paths. Among these options is also a Stay Single Path, where Becky engages in sexual encounters with various female characters, including her teachers, classmates, coworkers, and her nemeses, without forming romantic attachments.
However, the apparent peace following the timeline reset is disrupted when someone more evil than Septimus from Shelly's Future Past arrives on Earth to try and make life hell for Becky and her family, as well as Nyxara (Septimus' sister).
