You try.

You nod your head as you look at his cock. It’s now at least as wide as three of your fingers and a good foot long. Underneath you can see the largest set of balls you have ever seen, porn or not. They are huge twitch slightly in anticipation.

You start to lick his flared head as the deer at the front finishes whatever he was doing. “Thank you Mr Dearborne. Gazelle, you’re up, and I hope you know the topic,” the teacher says. He then looks down at you and you lean into his mammoth cock.

You lick it slowly to begin with, wetting his cock before taking the tip in your mouth. You start to suck as Gazelle starts to stumble her way through her presentation. By the time she is done, which is only a minute or two, you are feeling hot and horny. The debased nature of sucking off your teacher’s bestial cock as the class continues is quite arousing. You look up to see him staring down at you, he does not seem thrilled. You do your best to take more but moments after pushing your head down you pull back gagging.

“Well, I guess this isn’t going to work,” he declares. “Take your panties off.”

The authority he commands forces you to stand up and bend over to remove your panties before you even think about it. They stick to the wet arousal of your cunt. “Sir, I’m not on the pill.”

“And that’s my problem, you must be taught a lesson, and if your mouth isn’t up to the task, perhaps your pussy is.”

You bite your lip and quickly look around the room, Gazelle is back at her desk and is looking at you in glee. You decide to not give her the enjoyment of your discomfort. And, you admit to yourself, you are horny. Though if you could take this cock you don’t know.

Ungainly you climb astride him, as you find a comfortable position he calls another student forward. He is much taller than you, easily peering over your head as you prepare to fuck him. You reach a hand under you to guide him in place and part your lips with your fingers. Then you start to grind his head against your opening.

As you do you hear him moan quietly, “I’ve never fucked a human,” he says.

You find that you are in a completely submissive mindset as you say, “I hope you enjoy sir.”
