Buy the kid briefs

He already had what would be considered kid briefs, but his weren't actual kid briefs, the ones he owned were built for adults but with the design of kid briefs, with superhero logos and colors. He felt a rush of humiliation at the idea of wearing actual kid briefs, and even saw his dick twitch at the idea of acting like a kid peeing themselves (Just like he did until he was 8). Taking his wallet, phone and keys, Peter got dressed. There was a target only a block away from him, so he wouldn't need to take the train. Finally dressed, he rushed out the door. He walked as fast as he could without running in order to not pull any unwanted attention towards him. Finally making it to his destination, he calmed down, turning his phone on amd setting it to record, he placed his phone in the pocket of his shirt, making sure it recorded everything he was doing as he walked around to pretend he was looking for something, before reaching the children's section. Standing in the section, Peter grabbed the smallest briefs they had, which happened to belong to their superhero collection, bright red and yellow iron man briefs, baby blue captain america briefs, even blue and red briefs with the Spider-Man logo on them. Buying the whole pack, Peter smiled and lied, telling the clerk they were a gift to his nephew (who didn't exist).

Going back home, Peter rid himself of his clothes once again, staring at the pack of briefs. He couldn't wait to pee them, but also, he didn't want to pee yet, so until then, he would need to drink water and cum enough times to make himself want to pee. He could maybe first go to omegle and show off his tiny dick, or maybe he could humo the window.
