Artistic creation
On nights when there weren’t many tricks to go around Harley would sing, to entertain passerby, pass the time and even get some trick to chose him. He wrote the songs himself, and used the holographic interface in his forearm tattoo to record music to play as he sang. Eric would have a spot just a few meters away. After a few nights he joined in on the second chorus of Harley’s newest song, and Harley let Eric see the napkin on which he’d written the lyrics. Soon both of their forearm tattoos glowed and when the song was over they had sex.
