This is nothing more than a fantasy I had back when I was in class. It's fairly simple and no clever surprises unfortunately, but I feel it would be an appealing video.
Episode 89: Classroom Research
An attractive teacher around 30 is sitting at her desk. She's wearing a plain blouse and a very tight skirt. A class of fewer than ten college students is sitting at desks and writing an essay. Three of the girls are very attractive. We can hear the teacher's thoughts as she watches over her class. "That's it, work on this essay. Not that it matters very much. I've made sure that my targets are close to failing and everyone else is doing well."
One of the attractive girls is sitting in the front row and wearing a very short skirt. The teacher is watching her as the camera zooms up her legs until we get a glimpse of her panties, and it keeps a closeup on her crotch. The teacher's thinking again "That's a nice skirt you have on, Lauren. I can hardly wait to see you without it." On cue, the girl unzips the skirt and wiggles it down to the floor. She has on floral bikini panties, and she pulls them down her legs to into a pile. She continues to work on her essay with her legs apart, and teacher is just staring at the pussy.
Her concentration is broken when a girl in the second row stands up to sharpen her pencil. This is the most slender girl in the class with the smallest waistline. She has on a tight crop top and jean shorts. "It's about time you get up so I can see that yummy figure of yours," the teacher thinks to herself. The camera focuses on her. She takes off her tight jeans and t-shirt and then her underwear, then walks over to sharpen her pencil, then sits back down nude. The camera follows her closely. It remains focused on her when she sits back down. Then the camera returns to the teacher. She's biting her lip and writing on a slip of paper. She stands up with three slips of paper. She walks to the first girl and gives it to her. She gives one to the second girl. She walks to a third girl sitting in the second row. This girl has the perkiest tits - 32B or 33B. She hands the girl the paper and stands there and stares down her blouse. The girl pulls off her blouse and bra for the teacher to stare at. We see her read the paper which says "wait here after class gets out."
The teacher returns to the desk and stares at her class, especially the undressed girls. The bell rings, and we see the class leave. Then the camera returns to the three girls sitting in their chairs. We see them fully dressed, not as the teacher was imagining. "Lauren, Annette, and Martina, come up here." The three girls stand in front of the desk. "You know we have a test next week, and I'm concerned about you three. You're having problems in class, and I know that you need this class to graduate. I have a plan for you. I'll help you study, and I can guarantee that you'll do well on the test with my help. In return, I want you to help me with with a study for my PhD paper I'm writing."
The three girls are grateful for the help and ask what they would have to do.
"Nothing hard," the teacher tells them. "I'm doing research on contemporary sexual values, and I need to collect interviews of enough college-aged students to make the statistics valid."
The three girls agree to the deal.
She goes on to ask questions about their sex lives. She eventually asks them how often they masturbate and whether they do it to their own fantasies or if they're interacting with any websites while they masturbate. Lauren says she fantasizes about being in an orgy. Annette, the topless girl, likes to watch online porn while she masturbates. And Martina likes to fantasize about someone secretly watching her undress and masturbate. Next, she asks about their experience with girls [none], their interest in girls [slightly curious or kind of interested], and which girls they'd most like to have sex with.
