"Not really."

"Um," Nat swallows, then decides caution is the best option. "Not...not really."

"Boooo!" one of the boys calls. Several others take up the cry (and some of the girls do, too), and Nat blushes bright red. "Whattayou think, you're too good for dick?"

"Real women open up!"

"Yeah, not wanting cock is like...anti-feminist," one of the girls nearby complains. "That's like, slut-shaming the rest of us."

"Settle down, settle down, everyone," Ms. Poundwell says, sounding exasperated. Slowly, begrudgingly, the students do so. She clears her throat. "Well. I - of course what you do with your sexuality is your choice, Natalie! If you want to restrict yourself to simple courtesies like apology handjobs, or paying for things with your mouth, that's your choice. But I...have to admit it's pretty rare. And most people find it hard to get along in this world without sex! So I encourage you to...consider how you can find your way to some openness toward the idea. Whatever that is." She gives Natalie a kindly smile.

"Or at least some openness of your holes!" Trevor calls, prompting a new round of laughter.

"Enough, Trevor. Now, we need to move on. We were talking about the importance of sexual safety and the risks of NFE. So, one of the most important things for you all to learn is what the signs of NFE and sexual arousal are. Could...let's see...Amanda, could you come up here?"

"Um?" A tanned, doe-eyed girl with brown lank brown hair and a narrow face gets up, looking slightly nervous, and makes her way to the front of the class.

"Would you take your clothes off please, dear?"

There are some whistles and cheers, which Ms. Poundwell waves away. Amanda looks nervous. "Do I - do I have to?"

"Of course, dear, this is part of coursework." Amanda sighs, swallows, and slowly kicks her shoes off. Then she unbuttons her blouse and drops it to the floor, followed by her jean shorts. She hesitates just another moment longer - enough for Ms. Poundwell to say, "All of it please, darling," - and then unhooks her bra, dropping it on the pile, before bending over to take off her panties. There are some more whistles, and a bit of applause, from some of the boys. Several of them have opened their pants and are beginning to stroke themselves. Nat {if Sluttery < 40}tries to keep her eyes on Amanda and on her notebook{else}licks her lips unconsciously, leaning forward as she watches Amanda{endif}. The girl stands at the front of the class, attempting to cover her small, peach-like breasts with one arm and her cunt with another.

Ms. Poundwell drags a strange stool over to Amanda. "Thanks, dear. Hop up!" Amanda uncertainly sits on the stool and Ms. Poundwell briskly takes her arms and pulls them behind her, buckling her wrists into two cuffs that rise up from the stool's back. As Amanda gasps, startled, the teacher reaches down and pulls her ankles apart, spreading her legs and making her pink labia visible to the class. Amanda's ankles are locked into cuffs on the legs of the stool and as Ms. Poundwell steps back, it's clear that the girl can't move - she's totally exposed and helpless at the front of the classroom.

"Now, nymphomanic feedback effect can look a lot of different ways, but there are some common visual cues that can let you know where your partner is. And that's important to keep an eye on, boys, because a girl's mind is a very easy thing to break! But don't worry, Amanda, I'm a professional - and besides, it's pretty much impossible to get you there without cum, anyway. Now, observe..."

The next twenty minutes are startling and educational. Nat watches, entranced{if Sluttery < 40} and slightly horrified{endif}, as Ms. Poundwell proceeds to play Amanda like a violin, her hands - and occasionally toys - dancing over the girl's body to demonstrate the effects of different sexual stimuli. They watch Amanda's nipples grow painfully pointed, her clit swell, a flush spread across her tanned chest. They learn what she's into ("Did you notice how she moaned a bit when I grabbed her hair? That's a good indicator that she likes being dominated, boys!") and what she's not ("Notice how her body twitches away from me when I graze her asshole. That likely means she's nervous about that, inexperienced, or both. But she's still good and wet, because on a deep level her body knows that her ass is for fucking. You just have to be careful and gentle when breaking in a new girl. Get her good and worked up first, then she'll say yes to just about anything!"). By the time class is winding down, Amanda is a flushed, panting, quivering mess. Several of the boys have excused themselves to go find a blackband (Ms. Poundwell tuts disapprovingly at this, though she seems mollified when they return to class with the girl and begin quietly gangbanging her in the back of the class), a couple of the girls are shifting uncomfortably, lips parted and eyes glazed, and two redbanded girls are riding (what Nat presumes to be) their boyfriends' dicks while they watch Amanda's torment. Nat, for her part, is {if Sluttery < 40}both turned on and a little alarmed{elseif Sluttery < 60}as turned on as she's ever been{else}rubbing herself as stealthily as possible through her clothes{endif}.

Ms. Poundwell smiles as she finishes her lecture. "...And that's why it's so important to pay attention to your cunts, boys. As you can see, it only took me the length of class to turn Amanda here into a drooling mess - and I don't even have a cock!" She leans over and places an affectionate kiss on Amanda's forehead. "What a good girl she is. Well, we're pretty much at time. For tomorrow, I want you all to read the first chapter of your textbook: remember, for the boys, that's Control and Cum-mand: The Uses of Sluts in the Modern World, and for the girls it's All Holes at Heart: Female Solidarity in Sexual Service." The bell rings. "Dismissed!"

As Nat hurriedly gathers up her bag and begins to head out, she sees one of the boys approach Ms. Poundwell. "Sorry, Ms. Poundwell, but I'm still hard," he says awkwardly. "Do you think I could...I mean, do you think she would mind if I...?"

"You have to ask her, silly! But that's why I left her up there, yes," Ms. Poundwell says with a laugh. "Amanda, is it ok if Frank cums on you? I'll give you a nice orgasm if you say yes."

"I - I - what...oh, God...sure...yes...anything, please..."

"Thanks, Ms. Poundwell. Oh, God...ungh..." As Nat hurries out of the room, she hears Amanda gasp as the first shower of cum hits her quivering, aroused body.
