This fantastic idea was submitted by a patron last month, and it received the most votes! 

You arrive at your dad's house where you'll be spending the week, and you happen upon his girlfriend. She's beautiful, sweet, and pretty innocent... but that's not how you like your women. You like it when they're depraved, perverted, and slutty! You're not a huge fan of your dad, so you couldn't care less if this woman is already taken. You're going to corrupt her.
