Yes of course

You : Yes of course

Ms Ren: Perfect, let’s not waste any time then. Get under the desk.

You: What ?

Ms Ren: You heard me right John, get under the desk. Did you not forget who own the key to your chastity cage and who you own $100,000 to ? If I say this is the job of a teacher’s assistant, it is. You are going to help me releave stress while supervising exams, by sucking my cock of course. So get started now or I won’t count this hour.

You get under the desk and arrive in front of Ms Ren open legs, revealing her hard cock inside her skirt and start your work.

You suddenly hear the bell ring and students start to enter.

Ms Ren: Seat down, the exams paper on already on the table, you can begin.

You hear some giggles and realize this is an open desk and all the students can see your ass while you are sucking Ms Ren’s cock.

Ms Ren, mumbling to herself: Let’s grade last class’ exam. So... false... right... right... false... false. 2/5. Who is this ? Claudia... so a B+. Next. Right, false, right, right, right. 4/5. Adam, so... D-.

You : Gulp, gulp...

You, thinking to yourself: What ? She purposfully grades males badly to make them fail ? ... Outch !

You suddenly feel a sting on your ass. Then another. It seems some students made blowguns and are now shooting at your bare ass.

Ms Ren: Time's up ! Come all to my desk to leave your exams sheets.

You hear chairs moving and students walking towards the desk and leaving their exam sheet. Then suddenly you feel a finger in your asshole. It comes out as quickly as it went in. But a few seconds later, another one does the same thing, accompanied with a spank on your ass. Then, one of them goes a step further and shoves a big pen inside your ass and from then on, every futa student that leaves her exam sheet on the desk spanks you and either moves the pen inside your ass or leaves one more in your asshole.

When all the students have finished giving back their exam, you are left with multiple pens in your ass and red butt cheeks. Ms Ren uses decides to finish this class by grabbing your hair and forcing you to deepthroat her cock as she cums in yout throat.

Ms Ren: Class is finished. See you tomorrow. Make sure to find a job after classes to be able to pay for my tutoring.
