Being a pussy - you are in a classroom

You're at university, sitting in class. You're sitting at a small wooden desk, and taking notes by hand.
At the top of your page is written "MAG 369, Advanced Sex Ed".
"What the fuck?" You think to yourself.
"...and that finishes todays lecture on mana, as it relates to the female reproductive system" says the professor, lecturing at the front of the class. She's tall, slim, and wearing half-moon glasses. Her eyes scan the room, and she grins wickedly.
"Though, I imagine that today's material hasn't stuck very well, given your sure anticipation of the assignment."
Assignment? Oh shit, you didn't have any assignment ready! Though at the back of your mind, a new collection of memories from another world is prodding at your consciousness, suggesting that you haven't actually had to do any work for this assignment.
"Now, I want everyone to come up to the front. Boys to the left here, girls to the right. Come one, don't dawdle, we all know what's going to happen anyway. Remember, this assignment is mandatory for a passing grade."
Confused, and slightly panicky, you shuffle your way to the front of the room with the rest of your male classmates. The girls are blushing and giggling, glancing over at your group. You hear two of the boys whispering to each other.
"Bet you get Laura" says one guy to another. The two clearly know each other.
"No, bet you get Laura" says the other.
"You'll both get Laura!" cries the professor, cheerfully "and Laura is going to get a rare treat of an experience!"
How the hell did the professor hear them whispering? Oh, right. Magic.
The professor draws a wand out of her back pocket, and with a small flick, lifts the two off of their feet and pulls them forward to her desk.
"Laura! Please come forward, we have two volunteers who wish to know you better."
A somewhat shy, awkward girl walks to the front of the room, head hung low. The two boys have turned white as a sheet.
"Now Laura, you know how the spell works."
Laura is blushing furiously with embarassment, and keeping her eyes low. Slowly, she unzips her pants, and pulls them to her ankles. Her smooth legs are out for the world to see, crowned with a pair of pink panties. Laura stops, and looks up at her teacher.
"Panties too, I'm afraid. Remember, you don't have to worry about them seeing, they're going to be doing a lot more than just seeing in a moment."
Laura nods, almost to herself, and bends over to slide the panties down to her feet. You try to look away out of politeness, but can't help but sneak a peek at her pussy. It's wildly overgrown with hair, and you see the "volunteers" eyes go wide.
"Thank you Laura" says the professor. She raises her wand, the tip of which glows a furious orange, and the two boys dissapear in a puff of smoke. Nestled in Laura's crotch are now two pussies. Her bush has changed, one half is blonde and well-trimmed, the other is dark brown and shaggy. You realize that those are the haircuts of the two people who were just standing at the front of the room.
Laura quickly bends back down, pulls up her clothes, and retreats to the back of the girl's group.
"Take good care of them please, I'm sure they have a lot to learn from you." The professor looks down at a sheet of parchment. "That takes care of one of the extra boys, though one remains. I'm afraid that the straggler will have to be paired with me. Next up is... Jon!"
Almost in a daze, you walk forwards to the desk. Your heart is pounding with fear and excitement. Your instructor smiles at you warmly.
"Thank you for not making me drag you up here. Really, I think you'll find the experience to be... entertaining." She waves her wand again, and a large silver coin appears in your hand. You turn it over, and find that each time you do, there is a new name written on the other side. "Go ahead and flip it, dear" she says to you. You look over again at the group of girls.
You balance the coin on your fingers, and give it a flick. It spins in the air, and lands squarely in your palm. You look down, and read the name.
