Big Sis SPH

Your big sis is relentlessly mean and picks on you constantly. One day she's feeling particularly sadistic and curious about a little something. You see, she made a bet with her friends about you and she'll do anything to find out the truth. After pulling down your pants she cackles at your tiny pathetic dick! You are a virgin loser and you always will be with a dick like that.
