Period 3

Luna stood there in that bathroom, as the bell rung. She had just relieved herself in her diaper. One of the girls who took up a stall walked out, she went in as to not make herself look weird. She pulled down her diaper to her feet to assess the damage, completely soaked. She had really let go, once she started peeing, she went all the way. Another lady stepped out of her stall, she was going to wash her hands when she noticed the wet diaper at the feet of someone in that stall. As Luna pulled her diaper up and walked out of the stall she noticed the girl staring at her weirdly, before she left. Luna left to get to class. She was late anyways so she rushed, leaving a drip trail of piss behind. The diaper being wet stopped most of the crinkle noises at least.

Period three was gym for her. She got to the changing rooms. Most people already changed and left. She grabbed her clothing from her locker and changed in a private stall. She took off her dress shirt and shirt, and replaced it with some white running shorts and a rather tight shirt. The shorts went over her newly soaked diaper. She went out to the gym with the rest of her classmates. Since she was late the gym teacher decided to make her do 10 pushups while she gave out the rest of the instructions, Luna got down and did them as quickly as she didn't want anyone to look at her too long. The girl stands back up and joins the rest of class, they started with a warm up. Ten laps around the gym, Luna was quiet fit, so normally this would be fine. But under these circumstances, the diaper constrained her movement, she constantly lagged behind the rest of the group, to the point where she was eventually lapped by faster women. The end of the ten laps came and she was the last one of course, which drew some attention to her. With the warm up concluded they started getting into the actual sports, they were playing tennis. The broke off into teams of two, she groups up with Kim, they were just playing matches with a wiffleball against other teams. Throughout the period she was moving a lot, running around hitting the ball, she almost forgot about the diaper by time they had to pack up. Right as class ended she started getting this almost burning like sensation on her crotch, diaper rash... The bell rung and she went to her next class.
