Everything is pointed and named

"Now let's start at the top at the most important part for you all. Here at the top is the clitoris. Normally it's hidden, but if Natalie could slide open her lips for us we can see it."

She did as she was told, and with one hand, two fingers, she held open her inner lips.

"Ah yes the pearl. This is the most sensitive part of the vulva, and for the woman the most important part during sex. All of her pleasure comes from here. Now next we follow the lips of the vulva. These have the function of keeping dirt out of a woman's personal zone. There are many different types of lips, but it seems Natalie has... type 12 as we see on the slides."

For a second a few people looked up to the presentation behind her instead of to her wide open pussy. Only handfull though.

"A little further down we have the urine hole. This is where she pees from and it is NOT the same hole as the vagina. However is is almost impossible to see, and fairly unimportant anyways. But down here is the center of it all. The vagina. This is the hole where you guys "put it in" so to say."

Ms Pecker was really giving it all with this presentation. Natalie's heart pounded at the thought of someone inserting it now right in front of everyone. She was shaking all over her body.

"And we can just see the anus a little further down here can't we. Natalie could you lay on your back and spread your cheeks for us?"

She did as she was told. She laid down and with her arms along her body she pulled open her buttocks.

"We all know where this hole for is right? We all have one, also. It is also sometimes used for "anal sex" but I advice you guys not to get into this at such a ridiculously young age. I know you're all very worked up but just keep it natural, okay?"

"Right" the teacher concluded. "Any more questions?"
