Burp Contest with Little step-Sister

You're my big step-brother and you call me to let me know you're coming to home to visit. I ask if we'll do one of our burp contest and give you a sample of what I'm working with over the phone. Once you arrive, I bust out a few cans of carbonated beverages for each of us and we begin our contest. I clearly burp much louder than you from the jump, and taunt you relentlessly as the contest continues. I even burp talk and blow some burps in your face. I also tell you all my tips and tricks I use to get these enormous burps. Once I've finished putting you to shame with my massive belches, I get to burp in your face a couple times as my prize.
