Third Rail can be read as a standalone but chronologically takes place after Interborough in the Five Boroughs series. Christopher Mendez has always known his sexual identity had a swerve. No straight guy would have low-key lusted after his childhood best friend, right? Unfortunately, a combination of insecurity and overall lack of game has prevented him from further exploring his sexuality. That changes once he agrees to participate in a photoshoot for a queer dating app and meets Jace Fairbairn. Jace is beautiful, fey-like, and in an open polyamorous relationship with his gorgeous linebacker-looking husband Aiden. Once they set eyes on Chris, they’re instantly in lust and determined to broaden his sexual horizons. But what’s supposed to be a straight-forward sexual encounter gets complicated once a one-night-stand has repeat performances, and Jace and Aiden begin to fall in love. This collection of shorts explores the start of a relationship that eventually blossoms into something the three men realize they cannot do without.
