Biology 101, today the reproductive cycle.

Melissa came to college to become a biologist and today would be the first step on that path.

She was looking at her phone to check were Amphitheater 9 was when she bumped on someone.

After falling on her ass she quickly readjusted her skirt, hoping that the boy she bumped in didn't get a peek at her bare pussy.

To her surprise she knew him. Brian Holman was a boy from her hometown and they shared classes during all her childhood. She didn't knew he would attend the same college she did. They never had been close and she knew little about him.

"Oh, Melissa is that you? It's me Brian, what a surprise! I see you're trying a new look. " he greeted her.

" Hi Brian! What do you think of it? Can you believe that without my roommate I would have gone out in jeans and a sweater with some ridiculous plain underwear. " she joked about.

Brian couldn't believe his eyes. The usually modest but very sexy girl from his high school was there in a thigh sheer top and short skirt. He could easily see her nappies and could swear that when she fell he didn't see any underwear.

"Wahoo this is some change. You're going commando just because your roommate told you so? " he asked. The timid and modest girl he knew wouldn't be caught dead in such an outfit. To wear such a slutty outfit on the suggestions of a total stranger was unthinkable of her.

Unless...

He had heard of AGS on the news, Absolute Gullibility Syndrome. This rare condition made people believe anything said to them. If she fell victim to it, a simple remark from a roommate would have convinced her of wearing this.

It could open some interesting opportunities for him, he knew she was studying biology and they had the same class now. He thought that he had to test his theory.

"Professor Jones always has people do a project in tandem. You want us to do it together, right? He will object but you will have to insist" he declared.

"Of course Brian. I will do anything for that to happen. " she replied candidly.

Brian couldn't believe it, it was true. She had AGS and she had accepted to do the biology project with him. And he had an idea to make this more interesting.

The class was rather embarrassing, Professor Jones began his Biology course with a study of the reproductive system of various species.

Melissa was keeping her legs closed tightly , hoping to keep her teacher from seeing her pussy as he talked about those of various animals.

After some time he announced that each student should chose a partner of the same gender to do a semester length project.

Melissa raised her hand until her teacher asked her what she wanted.

"Couldn't I do it with Brian here? " she asked.

" I usual don't let couples do this thing together, I want students to work on this project seriously rather than just spend time flirting. " He replied.

" We are not a couple, he is just a former classmate from high school and we are both very serious students. " she pleaded.

" Well, I'll allow it but I will judge you on your result and if it's evident that you didn't give your best I'll fail both of you. " he replied.

Once every students were paired, one of each group went to the stage to pick a small slip of paper from an urn with their project on it.

Brian went to pick their project and put his closed fist in the urn and took it back holding a piece of paper. It had ragged edges and was of a different color than the others but it soon didn't matter to Melissa.

"Look Melissa this is our project choice. " said Brian, dissipating all doubts she could have developed.
