No

(What is he thinking, I am not a whore.)

"No, I will have to decline." You say.

"I see, then clean up and put your clothes on." He says.

"Yes sir, but um, this shirt is broken now, it wont close." You say.

"Look in the lost in found, in the teacher's lounge."

You leave the classroom and head to the women's restroom to clean up. You wash the cum off your face and hair and throw out your ruined shirt. You also clean up the cum on your pussy. You then head to the teacher's lounge, wearing only a skirt and bra. You go to the lost and found to try and find a shirt. There is only one in there.

(This isn't much better, but I guess I at least wont be so inappropriate.)

You pull the shirt, if you can call it that, on. There is a mirror in here and you look in it.

(ugh, it just had to be strapless, looks horrible with the bra straps showing... maybe I will try it without the bra.)

You take the strapless tube top off and your bra off. You then pull the tube top on and look in the mirror. It was clearly meant for a smaller chested girl but it does cover most of your chest. You can see your nipples poking out but it will have to do. You put your bra in the lost and found box and start walking back to class.
Your breasts bounce with every step, causing the top to slip down. You pull it back in place and enter your classroom.

"Welcome back Ms. Thompson." The principle says.

"So what can I do for you, sir?" You ask.

"I just wanted to see how your first day was going and to thank you for taking the position. "

"No problem sir, I just want to help them graduate and get into society."

"Glad to hear it, I will let you get back to it." He says as he leaves.

"Okay class, let's begin."

You start teaching the students. At some point, you are writing on the chalkboard when you notice your top slipping down again. It's not off, but your areola are visible.
