You two were arguing about him being gay and all so Johnathan decided to play along

Johnathan let out an exaggerated sigh, trying to play along with your antics once again.

"Oh god, we're doing this again? Okay, fine."

He cleared his throat and pitched his voice higher, as if pretending to be a girl.

"Yes, you caught me. I'm a girl pretending to be a guy this whole time."

He held the act for a moment, before smirking and resuming his normal voice, "But seriously, im not gay and im straight, okay?, plus there are a lot of cute girls"
