Halloween Party Dress up: Cross Dressing & Bi Encouragement From Your Girlfriend

We are headed to my coworker's Halloween party tomorrow night and you promised to dress up with me. I bought the perfect outfit for you: Naughty college girl. You've dressed up for me at home before so why not? You take hardly any convincing to agree to dress up but I want you to go a step further. I want to watch you make out with a random guy at the party. Come on won't you do it for me? I know you secretly want to.
