Some humiliation

For the first ten minutes of class nothing happened, but Brianna was practically holding her breath, just waiting, scared of what Mary Jane would do to her. And then, just as she began to calm down and reassure herself everything was fine, she heard Mary Jane whisper behind her.

"Moan like you were getting fucked hard", Mary Jane told her, and without being able to control herself, Brianna let out a fairly loud, sultry moan. She felt the blood drain from her face as at least half the class turned to look at her, including Mr. Dowdell, who was looking at her very sternly.

"Got anything to say, Miss Black?", he sternly asked her, and she remained speechless, shrinking in her seat under his gaze and feeling her cheeks heat up from her humiliation. She stayed silent until Mr. Dowdell turned back and got back to teaching the lesson, though some interest remained from her classmates, who began to whisper about what had just happened, gossiping about Brianna being a slut and masturbating in class.

About five minutes pass by, and things seem to normalize, but this time Brianna can't let her nerves down. What could Mary Jane do to her next? The realization that she could make her do anything terrified her to her core. She hated not being the one in control.

This time, Mary Jane gave her no respite, and just a minute afterwards, she heard what she had feared the most, Mary Jane's whisper.

"Now masturbate until I tell you to stop", she told Brianna, who was shocked by what the order entailed. She tried again to resist as best she could, tensing up and trying to stop her arms from moving, but once again it was utterly useless.

Her left hand opened her jeans silently while her right hand slid under her panties to find her awaiting pussy, which she was shocked to find was already wet. Shock nonetheless, her fingers quickly slid inside and she began to masturbate. She slowly moved her desk a bit do it would obstruct the view of what she was doing from everyone else, and did everything she could to stifle her moans of pleasure, which she was finding very hard to do.

She managed to continue masturbating for a while, but it was growing increasingly hard to keep her moans on the down low and remain unnoticed, and her face was also starting to get red, which did not go unnoticed. Then, just as she thought she was going to be found out, she heard Mary Jane again, saying the words she had been hoping for the entire time.

"You can stop", she whispered, and with a silent sigh of relief, Brianna pulled her right hand out of her panties, using her shirt to quickly clean the pussy juices still on it. She then closed her pants, and tried to focus on what was left of class to keep her mind off Mary Jane. Thankfully, she said nothing else for the duration of the class, but they did also have next class, physics , together too, and she dreaded what could come next.
