Craig wants to go to some scifi/anime/nerd convention, and Tweek wants to go with him, unfortunately Tweek gets really nervous in crowds. Really the only time he's not super anxious, and can relax for once, is when they're having sex. But it's not like they can have sex during the convention, right? It's not like Craig can put a vibrating butt plug in Tweek and use the remote to change up the settings while they're walking the con floor to keep Tweek distracted and aroused and calm ... Right?
