Slutty w/ your coworkers

Your GF Jenny goes to your coworker party w/ you. She secretly changes to a witch costume w/ just lingerie+witch hat, w/ her excited at all the male attention+flirting w/ all your male coworkers. Jenny insists that she is loyal to you, but she just wants to show off what a hot GF you have to your coworkers. Your male coworkers are staring at her barely covered boobs, while the female coworkers are enraged, coughing loudly while saying the word "slut". Will you let your insecurities ruin your GF's fun...or do you wanna see how much more flirty she gets as she gets more drunk?
