Sibling rivalry.
She knows you can see her. You already commented on how "unlady like" she was sitting and now shes digging at the side of her "lip" with the back of her fingernails. You could swear you can smell her reak as she scratches parts of herself no brother should witness but her room smells so much like pussy anyway it's impossible to tell if its from her scratching her crotch or the dildo thats poorly hidden under her pillow. Either way your losing this street fighter match because your minds on the joystick in your pants and not the one in your hand and she knows it, even if she stinks.
The shame game.
Class clowns from the beginning and college is no different, you and your friend made getting into trouble a hobby. Embarrassment is the name of the game as you and them constantly dare each other into greater depths of depravity. He dared you into blowing him on the train ride and youre still not sure what was worse, the sweaty taste that lingered until the toothpaste washed it out or knowing how many phones were out as you spit shined his mushroom tip publicly. The only thing to fix it is to find something worse for them to do.
