A "Fateful" entrance?

As she was about to open the door with her free hand, she checked herself one more time, noticing that a small portion of her ass was on show, it was just the upper part, along with the thong's strips. Ari tried to ignore it as she fastened her grip on the front waistband. After a small breath, the door was opened.

The teacher was nowhere to be seen, and her classmates didn't even notice the door opening. Arianne sat at the back of the class, in the left corner of it. The seats were distributed in three vertical rows, with quite some space in between them. Ari began making her way to her seat, changing her grip to both hands on both sides of the pants.

Nobody in the class noticed her weird behavior, she was often overlooked by everyone in almost anything, so no one cared to see what she was up to. She had her back slightly towards the direction she was heading, like a weird hunchback.

Finally she got to the last row, in which she sat, making her way in front of the classmates that sat beside her. Ari was slightly blushing, as her weird way of walking finally got some stares from her classmates.

"Why are you so inclined? And did you forget to wear your belt?" Commented one of Arianne's classmates as she passed in front of him, the guy even had a 3DS in hand.

"I-I...yeah...I-I forgot m-my b-belt.." said Ari, finally beginning to blush hard, she hardened her grip on her jeans and just quickly walked up to her desk.

The girl beside her kept her attention on the book she read, and Arianne finally sat on the desk, taking her hands off the pants after sitting, letting a huge sigh of relief.

Few minutes passed, Arianne looked across the classroom to see if anybody began snickering on her predicament. Nobody did. The teacher finally entered the classrom, Ari was somewhat glad she got to class early. Now she just needed to get her change at the locker rooms.

Things seemed to improve, until suddenly, the only person that Arianne didn't want to see got to the class right after the teacher arrived, holding the door just before it shut.

"Mr. Harrison, just in time for me to punish you for arriving late in my class again." Proclaimed the teacher.

"Thanks for the warm welcome." Replied Tom, making everyone in the classroom burst in laughter, except for Arianne, who was dumbfounded and legitimately horrified for what was to come.
