Jake was furious! Now his brother was beginning to overtake Jake's old life as the studly older brother. Jake left his brother to continue sleeping with what used to be his girlfriend and went to the kitchen to formulate a plan. Jake sat at the table, noticing how much higher the table was for him now, cursing his smaller frame.
Less than a few minutes into thought, Jake hears someone outside leaving from his house - "she must have snuck out so I don't see that she cheated on me with my own brother" Jake thought. A short moment later Jesse swaggers into the room, shirtless and displaying his sprouting chest hair and treasure trail. Jesse stretches in front of Jake, displaying his new muscles and almost flexing them in the process. Jake is green with envy seeing his younger brother looking almost as buff as he used to be - maybe even cockier too.
"Sup LIL bro?" Jesse says emphasizing the "lil" of "lil brother". "How did you sleep last night buddy?" Damn, his brother even had a deep voice like a grown man.
"ShUut uUup" Jake replied, surprised by his voice cracking.
"Oh nice bro, looks like you are starting to hit puberty finally. In a few years you might be as big as me" Jesse replies, rubbing his large bulge through his strained boxers.
"What are you talking about Jesse? You know I'm older than you. It's just my dick that makes you LOOK older." Jake was confused by his brother's behavior.
"Pfft what lil bro? Too much video gaming must have rotted your brain bro. I've been the older brother, I had this dick since I was your age. Even though you are a late bloomer, I am sure that won't affect your maturation."
Jake was mortified, had something changed to make it that he wasn't the older brother any more!? Jake fled from Jesse and ran to his room to try to figure out what happened overnight.
