CJ is a sex worker that Agustin meets after getting fired.
Agustin meets CJ at a bakery where he is brooding over getting fired from his job as Stina's assistant. After hearing CJ on the phone giving a price per hour (around $220), Agustin learns that the latter is a sex worker, and then he gets his card.
At the Folsom Street Festival, Agustin finds CJ again and asks him to help with a new art project. CJ asks if Agustin actually wants his help or if he just wants to sleep him, and Agustin promises that it is a real project. CJ agrees to help but says that his rate is $220/hour, which Agustin agrees to pay.
