The third title in the Reversible series, Some Fun Before We Reverse This, follows two roommates, Nick and Trevor, as they both agree to join the fated BioFem experiment that will transform them into women. Like Mike and Dan before them, their lives change when they attend the first orientation and receive their first dose.

Nick is a struggling Lyft driver, trying to make ends meet until he can find more permanent work. When an angry passenger hijacks his car and sends Nick to the hospital, Nick decides he is done. Attracted to a posting for the BioFem experiment, he decides to make the call to register.
Nick's roommate, Trevor works remotely as a programmer for a software company in another state. Tired of being JACM (Just Another Code Monkey), he agrees to join Nick and attend the orientation.

Knowing that they will reverse their sex changes after the study is done, the two men decide to experience all they can as women before they reverse their changes. Then, BioFem management gets involved and wants to throw a little change into the protocols.
