Tell Sophia to have Zach call her by her brother's name next time

You thought it was hot how Zach went along with Sophia fantasizing about you. You wondered what else he'd go along with. Would he play along with **** fantasy if Sophia started calling out her brother's name as they fucked? You decided to find out.

You tell Sophia what you want her to do and tell her to report back to you. You wondered if she would balk at the idea of pretending to fuck her own brother, but she reacted with excitement - focusing more on how she'd be belittling her boyfriend and dragging him into a taboo rather than her own involvement.
