Alex Chance is the dirty babysitter.

You're about to walk in on your babysitter masturbating and to be quite honest, you're not surprised at all. Her name is Alex Chance, and your wife never really liked Alex, due to her "slutty appearance" and "suggestive jokes". In fact, you're not even allowed to hire Alex anymore but since your wife's away on a business trip, what she doesn't know ain't gonna hurt her, right? It's amazing what these sluts will do for a little extra "somethin' somethin'" added to their pay, isn't it? Enjoy my stepbrother!!
