"I hope so as well," he says

"Though I hope you don't enjoy it too much as this is meant to be a punishment for you being tardy," he adds in a whisper.

You push down onto his cock and feel the head stretching you wide. You both moan as you slowly take his girth. "Oh God, Sir, you are so thick."

He grabs your waist and starts to lift you and push you down slowly. You moan loudly as more of his cock fills you. "Quiet," he orders, and you find yourself again complying.

As the student makes their presentation, the rhino continues to fuck you. You feel yourself shudder and cum on his massive cock and look down. His cock is almost a foot long, and you have only taken half of it. It glistens with the juices of your arousal as you try and take more. When three-quarters of it is buried in your snatch, he tells you to hold on. You are not sure what he means but do as directed, gripping his shoulders tightly as the final student finishes their presentation and returns to their seat.

As the student sits, the teacher stands, and you sink further onto his rigid cock. "Oh fuck yes," you yell. There is a snicker from the students as the teacher starts to talk while you are impaled on his magnificent cock. "As you can see, class," he begins while twisting his hips up and down, effectively causing you to bounce on his cock. "The changes our society has had over the last fifty years has been great. With further integration," he looks down at you, "we don't know what we could achieve."

His cock head is pushing against your cervix as he talks, and you shudder and slip. Your hands come free of his shoulders, but incredibly the massive stiff member holds you mostly upright. As you swing backwards a few degrees, your head lols back, your eyes are rolled back, and your mouth hangs open in bliss. The class laughs.

For the next twenty minutes, you are impaled on his cock as he continues the class. After a short dialogue, he tells the class to start reading at chapter four. He then lays you down over the desk and starts to fuck you in earnest. As he is pounding your human pussy he whispers to you. "You are so tight, I hope you continue to be tardy, but if you miss any assignments while you are here, you will need to find a way to make that up."

You nod as your tits bounce about in your uniform, "Yes, Sir," you pant, hardly processing what he was saying.

You lose count of the number of orgasms you have before he announces that he is going to cum. As he says that, the bell goes, and the students rise and start to pack their things like this is the most normal thing in the world. Then you feel it. A hot torrent of cum fills you, and you scream, shuddering over him. The world goes white, and you lie there shuddering. After a few moments, you feel him pull his slackening cock out of your cunt and steps around to your head. Without being told, you open your mouth and let him put his still thick but softish cock between your lips. You suck him clean like you have seen in porn moaning the whole time.

Then he steps back from you. "Clean the desk. Then you can go. I expect you to be on time in the future, and you should hurry. You wouldn't want to be late for your next class."

"Yes, Sir," the words drool from your mouth.
