You've been attracted to your girlfriend's sister ever since the day you first saw her and heard her say "watch where you're going loser" as you bumped into her in the hall, of your girlfriend / sister's place. Ever since that day you try to subtly get her attention because you're a dirty whore that can't get enough. Your girlfriend's sister knows exactly what's up. She finally confronts you one day when you come barging in her room with some lame excuse to be near her and talk. She tells you how much of a boring disgusting loser you are and also expresses to you about how you'll never get a chance with her before kicking you out.
