You and I are hanging out after not seeing each other for a while. You are seeing a new woman, and you're excited to tell me about her. I eventually let it slip that I actually know your new girlfriend, we have quite the intimate relationship.

See, your beautiful new lover is also my Toilet Slut. That's right, I've been using your girlfriend as my dumping ground for the past two years. Imagine all the filthy things that sweet mouth has been up to!
