Use the cup

Nate grabbed the empty soda cup and held it down low. He slid down, slouching, and pushing his crotch towards the edge of the seat. When he thought that everyone was focused on the movie, he tried to nonchalantly pull his cock out and put it in the cup. He would have preferred a louder part of the movie to cover the noise, but he couldn't wait for that, not like he was now. And so he let go of his bladder and piss shot its way out of his urethra, rapidly filling the cup with warmth.

He saw his mother turn her head at the sound of his stream. He tried to lessen it but once he had opened the floodgates he found that he couldn't stop. He would be able to stop peeing until he was done, which was uncomfortable when his mother looked down at where the cup was and realized what he was doing. She had a look of **** anger and disapproval on her face. She shook her head at him with a tight lip. She even mouthed the words "no" and "stop," but he physically could not, but he didn't think that she would understand that.

At this point his sister had noticed as well, and was torn between the disgust of the sight and the joy of knowing how much trouble he was in. His father had almost definitely noticed too, but was ignoring it in favor of the movie, letting his mother do most of the non-verbal chastising. However, it didn't seem like any of the other movie-goers noticed what he had done. The theatre was mostly empty anyways, and those that were there were too focused on the movie.

When Nate was done he had nearly filled up the entire cup. He felt the warmth in his had as he held it and put it back in the cupholder with the lid on it. After that they sat through the movie with an awkward tension between all of them. At one point his mother left to go to the restroom and his sister followed her, leaving him with is father who didn't want to deal with the situation. When his mother and sister got back he read their minds and saw that in the bathroom his mother exclaimed her disbelief at what he had just done, and in public no less. His sister chose that opportunity to exaggerate his situation by teller their mother about how he peed off the balcony in the early morning. His sister still wasn't completely certain over whether that incident was real or not, but it didn't matter as their mother was likely to believe it anyway.

When the movie ended, every naturally waited for the end credit scene at he end of every superhero movie. The lights came on and his mother, who had had some time to focus herself so that she didn't appear quite as angry. She was still plenty angery, just not as likely to yell as she would have had she gotten the opportunity earlier. He tried to tell her that she gave him no other choice and that the situation was complete unfair, but she would hear of it. She could believe that he had done something so obscene, and they all agreed that something needed to be done about him.
