You enter your room, 5001. It's structured really weirdly. Instead of a bed, there is a nest like structure in one corner of the room. There is a small stool next to a low-medium table, which has a bowl of birdseed on it. The shower is double wide, with shampoo and conditioners that have names like "Fur-Shine +" and "Feathery Luster." A second door leads to an open air balcony, which shouldn't be possible, since there are rooms on the other side of this hallway.
A note is on the table - "Come to class completely naked. Class will be held in the courtyard. Use second door to enter. - Mr. G. Gryphonology Professor." You shrug, and undress yourself to the skin, exposing your small A-cups and vagina. Then you walk through the door to class.
There are not a lot of students in the courtyard, around 14, about 50% 50% between male and female. You decide to sit down next to a guy, he seemed friendly, and later introduced himself as Samuel. "But I go by Sam," he said.
"That's so funny!" you chuckled, "My name's Samantha; I also go by Sam."
Just at that moment, the Anthro Gryphon at the front of the group cleared his voice and spoke, "Good morning class. I am Mr. Frank Gersarion. But you may call me Mr. G. I am your main professor. In a moment, you will all form a line to get the vials that will transform you into Anthro Gryphons, of a species of your choosing. For the best way to learn about these magnificent beasts is to become them."
Sam nudges you. "This is so exciting!"
"Now. A few things to note. You will be fully transformed into gryphons. This includes reproductive systems. To prevent unscrupulous actions, you will all be biologically neuter. This means no reproductive organs. Females may notice their clitoris sealing up, turning into a small pinhole for liquid waste, and their breasts shrinking into their chests. Males may notice their penis and balls shriveling up, until their testicles are gone and their penis is only a small pinhole on their groin. If anyone wishes to drop out, do so now. Otherwise, come, and take your vial.
