Step Bro

C’mon mane! We all know why you searched this up!

A Step Bro is a person that all straight men can respect, but don’t wish to be. The Step Bro usually is asked for help by his Step Sis, however, he does a bit more than just help.
His body is usually scrawny, due to the majority of his time going into gaming, and his lack of physical strength makes his appearance rather “unpleasant”. But oddly enough, he is packing somewhere around 6-10 inches. “Like he’s ever going to get a chick?” That statement is beyond wrong! His chick IS his Step Sis!

Dickie: CuM MeaT Ya NeW STeP SiBLinG, TrEVOr!
Trevor: uh... hi!
Helen: awww yeah! My Step Bro finally came! You look HANDSOME! *lets out a slight moan*
Trevor: *Pulls our a cross* BEGON, WENCH FROM TIMES OF YORE!
Helen: bruh.
