Step - brothers!!!!!!!!
Main and his step little brother run into each other on the street each with another man. At home they confess to each other that main has always been strictly gay while brother had a sexual bi awakening after his last girlfriend poked holes in his condom. Main admits he was with his boyfriend while brother was with a random hook up. Things go ok for about a week until brother hears main talking on the phone with his boyfriend. After hanging up main start to jerk off, which tiggers brother into also jerking off with him. Brother then starts to avoid main, because now to him their relationship has taken a turn.
Really thought this was true full brothers which was weird and gross. Still not a fan of step sibling relationships so this was still up there in the not good category. I guess it was fine if you ignore the step sibling theme which is a little difficult so it was hard to digest.
