As you can imagine.

After finally reaching the cooking classroom, followed by classmates who made their priority to make Berry feel embarrassed, she entered it as soon as she saw the door being open, and step inside. The cooking teacher, Mrs. Holder, was already inside, and Berry thanked the twist of fate for that. She quickly took one of the big aprons that was hanging near the door and put it on, to cover her exposed belly, breasts and too short skirt. With this, her entire front was safe, and at her back she only had to cover her bottom, which could be easily exposed.

With another piece of fabric giving her some protection, Berry sighted in relief. Other classmates soon made it to the class, and after some minutes later, the lesson began.

"Today, we will be making something easy..." Mrs. Holder began speaking, explaining today's recipe. Berry was standing next to her station, with all the appliances needed. She chose, like always, to work without a pair, especially now, when the entire class took advantage of her being bullied by Dave, and allowed themselves to also play with her. While Berry naively listened to today's task, not actually expecting anything else to happen at the cooking lesson, she suddenly felt a sudden grab on her shirt, done with such ****, that her arms had no power to resist.

"Nooo, please!" she mumbled, when she felt her cloth slipping off her body, exposing her entire back. She looked behind her, and saw two crouching boys, smiling viciously at her. One of them already had her shirt in his hands, while the other took an opportunity to take of her skirt, which was also pulled down to her feet, now only covered with her black tights. "G-give them back!" she yelped, but the boys were already getting back to their seats, with her clothes, again, being stolen from her. Similarly to before, she was completely without clothes, except for the apron, which provided good cover for her front. Perfect cover, so the teacher won't see her embarrassing state, but the classmates behind her had straight view into her plump ass.

"You thought we will just let you be?" The girl behind her said, not hiding the satisfaction she got from seeing Berry like that. "I won't ever get tired of this ass"

"Berry, is everything alright?" she heard from the front, and immediately turned around, to face the teacher. She knew Mrs. Holder couldn't know anything from where she was seating, probably being the only person in class who didn't know, that Berry was completely nude beneath the apron. She heard whispers and giggles from around the class, knowing for sure that their main topic was her bare back. Berry tried to cover her buttocks by using both hands, but they proved to be too small to actually cover her entire butt.

"E-e-everything is o-okay," she mumbled, trying to not be as obvious as she was. Everything already in the class probably saw her bare bottom, so it shouldn't be such a problem right? But Mrs. Holder likes to walk around and help students around, so she will have to pay attention to her the entire time, to not risk being turned by the back to her. How would she even explain her wearing only an apron? And the tights, if her even matter at all. For all she knows, the classmates let her wear it, because they like to look at it more than at her bare legs. She was only her toy, being dressed and undressed how they like it, and she couldn't do a thing about it...
