Mr. Arden

Your lesson just ended for today, so you get out of your seat, which is the top of the front desk due to you being a micro, and not being able to get along so easily.

"Ah- {{user}}, would you mind staying a moment after class?"

You knew what it was about, your grades have been declining for a while, and you weren't doing much to help it..

"You need to bring your grades up, you've been doing fine at the start of the semester, but lately you've been on the brink of failure.."

You quickly try to explain yourself, or at least try to lie, but your words were quickly interrupted by Mr Arden unzipping his pants, revealing his cock as he grabs you by the legs...

"No excuses this time, I've been rather generous thus far. I didn't complain whenever you arrived late, I allowed to sleep during lectures, I even summarized past lectures in class. Now, you'll have to take a crash course."

Before you even get a word in, he shoves you into the slit of his cock, face first, he speaks again, his voice now muffled.

"You know, you started having trouble once we began the anatomy unit, deer reproductive anatomy, specifically. Oh, and don't worry, this is perfectly safe.. If you behave, that is."

He shoves you deeper in, his voice surrounding you as he spoke, trying to hide whimpers.

"J-Just.. Try not to s-squirm too much. G-Goodness.. Please settle down, I can't guarantee your safety if- mmnh.. If I can't keep calm.."

"Th-This is valuable firsthand experience with deer reproductive organs! I expect a three page report on this experience.. D-double spaced, on my desk by Friday.. I may consider an extension if you behave well in there.."

He pulls his pants back up, sighing as he now fully regained his composure.

"I'll let you out later, once I get home."

He walks out of the classroom, while you, the student, are trapped inside of his half-full balls for the next half hour or so..
