Two more items down

As the professor continued his lecture, only occasionally referring to her, he started to grope her. At first she thought it was part of his lecture, but then she realized it was her free use trait coming into effect. Even if she hadn't agreed to stay for this lecture she would have been unable to stop him without everyone getting mad at her.

"Alright I need some strong volunteers, oh you two. Could you bring that apparatus onto the stage please?" The professor selected to guys sitting near the front and pointed to something offstage Lara couldn't see.

As they brought it closer she seriously considered refusing, but in the end she let them. They brought over a bench of sorts and bent her over it. The top was padded with spaces for her breasts and face so even though she was pressed down against it she was rather comfortable. At least physically. Mentally she was struggling with the idea that she was nude and bent at a 90° angle with her pussy on full display to hundreds of people. They even locked her ankles to the bench so she was incapable of closing her legs even the slightest bit.

The professor continued to talk, occasionally touching her vulva, even spreading it apart. Then he started talking about how large a vagina in, how it can stretch. That scared her. She kept picturing a comically large dildo in his hands.

"Now I had considered demonstrating this, I did find a rather large dildo online," Oh no...wait, he said had considered. So he wasn't going to? "But the truth is many women cannot cum at all from penetration. Instead I want to show you all what a powerful vibrator can do, and demonstrate how women can experience many orgasms in a short period of time under the right conditions."

She heard a buzzing noise and then suddenly felt it against her clit. She couldn't help by cry out in pleasure as it touched her. Like the professor said she demonstrated for the class all right. She came, and then again, and then again until she was begging them to stop.

Finally it did, "As you can see class too much of a good thing can become a bad thing. Now our time is almost up but I want to give everyone the chance to come and see the female anatomy up close. Take notes, you may be quizzed on this later."

Lara groaned, hundreds of people were about to get up close with her vagina....and they would be taking notes. This was just great. Amira owed her. Big time.

"Professor," Lara heard a male voice say, "Are we allowed to touch?"

Please say no, please say no...Lara thought.

"Not today, maybe Lara would be willing to stay after the lecture but we need to keep the line moving so everyone has a chance." The professor answered. Stay after? Fat chance. At least he'd said no though. The professor continued to talk as student after student got the chance to examine her sex, but finally it was done. He dismissed the class and released Lara from her bondage.

"Thank you so much Lara, I'm sure my students are well prepared now. The box with your clothes is...oh...it was right here..." Lara looked around, it was gone. The professor frowned, "I am so sorry. It looks like someone stole it," Lara looked around, the hall was almost empty now, "Oh Lara, there it is!" He pointed.

Lara, not caring about her nudity anymore, sprinted towards the box. Except her clothes were not there. Only her cell phone remained. So thee person who took them was trying to be a perv, not a thief. Great. She would have to run home naked...wait.

"Hey does anyone want a photo?" She called out loudly. A few people stopped, "I'm serious. Let's take a selfie."

There weren't many left in the hall, but she found 10 people willing to take a naked photo with her. At least she'd finished two things on the list.

Before she left the professor stopped her, "Sorry I couldn't find any clothing but here, take my jacket." He handed her his sports coat. It was long enough that it would allow her some modesty on her run home.

"Thanks, I'll uh, return it later ok?" The professor nodded and Lara hurried back home.
