"Welcome, everyone!" Mr. Johnson says as the class finished filing into the room. "I hope you all had a good weekend and are ready to learn, because we've got a very important topic to cover today."

There are some good-natured groans at this pronouncement. Johnson smirked. "Try to contain your enthusiasm, kids. Now, today's lesson is going to be awkward. That is simply an unavoidable consequence of the subject matter. But it is also very, very important, particularly to people your age. You can pretend to be embarrassed all you like, but I was your age once and I know I thought about it all the time. Today's topic is sex--we are going to cover basic male and female reproductive anatomy, the basics of sexual technique, how to have sex safely, and the manner in which procreation occurs."

There is some shocked muttering and even some awkward laughter.

"See, that is the first lesson," Johnson continues. "Sex is not, in and of itself, something to be ashamed of. It is a very natural thing to do, and it’s natural to want to do it. Some of you have probably already had it, even if you don't want to admit it aloud."

"For that purpose, I have received permission from the school administration to do something very new and exciting for today's lesson," Mr. Johnson adds. "Jack Burke and Emma Winston, would you both please come to the front of the class?"

Jack, a tall and lanky guy with messy brown hair and bright green eyes, gets out of his desk chair and goes to the front of the class, feeling surprised and rather embarrassed at having been called on. He is joined a moment later by Emma, a petite, shy, quiet, and very pretty girl with long wavy auburn hair and captivating hazel eyes. The two don't know each other very well and have only spoken several times. Both of them wonder what Johnson has planned.

As they both stand in front of the class, the teacher says, very calmly, "Jack and Emma, I want you two to demonstrate sex to us. You have been chosen randomly to have intercourse during this lesson, providing us with a visual demonstration of how it works in in practice as well as in theory. More, you are to conceive a child together, which should not be difficult as the nurse has informed me that Emma is currently at the peak of her fertility cycle. We will follow the course of the pregnancy for the rest of the semester, up until the point of delivery."

There is a collective gasp from the class, which Johnson ignores. The bottom falls out of Jack's stomach and Emma can only stare, her mouth gaping in horrified disbelief.

"Wh-what?" she asks, her voice trembling. "I have to--w-we have to--"

"I believe I made myself clear the first time," Mr. Johnson says sternly. "You two are going to show us how human sexual intercourse and procreation works."

Jack and Emma cannot believe what they are hearing. Neither can the other students. How this possible? How is it even legal?

"What...what if we don't want to?" Jack asks. "What if we refuse?"

"Then you both face severe disciplinary action by the school, up to and probably including expulsion."

Jack looks at Emma, clearly scared and uncertain. Emma's eyes are wide with disbelief and horror. "But...but Jack and I don't even know each other that well!"

"That hasn't stopped people from getting pregnant in the past," Johnson says dismissively. "It will not stop the two of you, either.

Emma falls to her knees, her eyes brimming with tears. "Please, Mr. Johnson," she begs. "Please, please don't do this to me. I'm too young to be a mom, I'm only eighteen!"

Johnson glares at her. "The decision is made," he says firmly. "And there is nothing you or I can do to change it. If you persist in these theatrics I will have to send you to the office for insubordination."

Emma buries her face in her hands, weeping softly. Jack's heart lurches at the sight of it. He's not happy either, his blood is ice in his veins.

"Oh, do contain yourself, girl," Johnson snaps. "And buck up. The school will provide you with a generous stipend once you carry the child to term, should you choose not to adopt it out. You might find some peace of mind with that. But if you do not pull yourself together and do as you are told the consequences will be severe. Do you understand me?"

Emma looks up, her eyes red from crying. She nods, unable to speak. What can she do but obey? She can't be expelled! At least, if she has Jack's baby, she can go back to school at some point in the future. But if she's expelled, any chance of furthering her education is permanently gone.

Jack wants to say something, to comfort her, to try and do something to make her feel better, what can he say? He is as powerless as she is--nothing he does or says will change what he and Emma are being forced to do.

"Very well then," Mr. Johnson says. "We'll begin. We have much to cover and only two hours in which to do so. We will start, of course, by disrobing. Emma, I want you to stand up and undress Jack. Slowly, and with care, so that he doesn't feel uncomfortable. Then, I want you to guide his hands and show us how to touch and explore a woman's body. Understood?"

Emma's heart feels like it's going to explode out of her chest. She's never been so close to a boy before, let alone undressed one. But she does as she's told, meekly stepping closer to Jack, and taking a deep breath. Her hands tremble as she begins to unbutton his shirt, revealing the defined muscles of his chest. She's never been this close to anyone before, and the warmth of his skin against hers sends a shiver down her spine.

Jack can't believe this is happening. He's terrified and ashamed, and he knows this is wrong, but he can't help but feel a strange excitement too. Emma's touch is very gentle and soft, and the way her hands move over his body makes him want to moan. He tries not to think about the consequences of what they're about to do, focusing instead on the moment, and the girl who is undressing him.

Jack's shirt is now off, revealing his muscular chest and defined abs. His cock, already hard from the anticipation of what is to come, stands at attention as Emma fumbles at his belt buckle with her slender hands. A moment later, his jeans slide to the floor. Emma takes a deep breath, feeling her own body responding to the intimacy of the situation. She hooks her fingers inside the waistband of his boxers, and pulls them slowly down to his ankles. Jack is now completely naked before her.

His cock is thick and hard, and Emma can't help but stare at it, feeling a mixture of fear and arousal wash over her. Mr. Johnson clears his throat impatiently, reminding them that they have more important things to learn. "Now, Emma," the teacher says. "Demonstrate to us how you enjoy being touched, but do not undress just yet. We will come to that in a moment. For now, show us where the sensitive parts of your body are and Jack will touch you in those places however you like. Class, this is very important because each person has their own unique erogenous zones. Knowing yours will make your own sexual experiences much more pleasurable."

Emma swallows hard, trying to ignore the way her body responds to Jack's presence. She nods and begins to show him where she likes to be touched, guiding his hands over her body. As he touches her, she tries to focus on the sensations and forget about everything else. "M-my breasts," she says, her face turning red with humiliation. "I...I like being touched there, and...and between my legs too..." She swallows hard. "If you do it very gently."

The class makes a collective "Oooh!"

Emma's face burns even hotter as Jack gently takes one of her breasts in his hand and begins to explore it, feeling it and squeezing it gently through her shirt and bra.

"And here," she whispers, guiding his hand between her legs. She's never felt anything like this before, the sensation of his fingers touching her there. Even with her panties on, it's so intense, it's almost painful. "I...I like this, and...and this," she says, spreading her legs a little wider so he can touch her more easily.

Jack's heart is racing as he touches Emma's body, feeling her soft, warm skin against his fingers. He's never been this close to a girl before, and it's all he can do not to lose control. As he touches her between her legs, he feels her body tense and shudder beneath his hands. "Is this...?" he asks, afraid to make the wrong move.

Emma gasps and arches her back, unable to form a coherent response. She's never felt anything like this before, and it's taking every ounce of her self-control not to moan aloud.

The class watches in rapt attention, some of them blushing with embarrassment and others growing aroused by the display. The tension in the room is palpable, and everyone holds their breath as Jack continues to explore Emma. He can feel Emma's body responding to his touch, her breath coming faster and her hips beginning to move in rhythm with his fingers. He knows he shouldn't, but he can't help but fantasize about what it would feel like to be inside her. The urge to feel her wetness against his skin is overwhelming--

"I think that's enough for now," Johnson says, using his hands to separate them as his voice jars them back to reality. "Note, class, the classic signs of growing arousal from our two volunteers. Flushed cheeks, heavy breathing, dilated pupils of the eyes, heightened heartrate. Jack, in particular, seems quite turned on indeed. Before we continue though, a few questions. Emma, of the different places Jack just touched you, which did you enjoy most? What would you improve on next time?"

Emma blushes even deeper, her face flushed with embarrassment and desire. She takes a deep breath before answering, her voice barely audible. "I...I enjoyed it all, but...but I think I liked when he touched my, um...you know." Her face heated up even more than it was already. "And...and next time, I think I would like to be more confident."

"Confidence is certainly important. And what about Jack, Emma? What can he improve on?"

Emma glances at Jack, her cheeks burning. "He...he was very gentle, and he listened to what I wanted. I think he did really well and I don't really have any, um, criticisms."

Jack feels himself blushing as well, embarrassed by the praise but also aroused by Emma's words. He looks at her, hoping she's being honest, and not just trying to make him feel better. He takes a deep breath, trying to focus on the lesson. "Well," he says, "I think I could have been more assertive when we were talking about boundaries, and making sure we were both comfortable with everything." He looks at Emma, wanting her to know that he's learning from this experience.

"Another question," says the teacher. "You are probably feeling a mixture of intense emotions, too. Would you describe them to us?"

Emma bites her lip, debating how honest to be. "Well, I...I feel embarrassed, of course. And a little nervous because everyone's watching. But I also feel...excited, and, um, a little turned on." She looks down at her lap, blushing even harder. "It's kind of hard to explain."

"And none of this is affected by the knowledge that you will in all likelihood get pregnant today?"

The teacher's comment catches both of them off guard. Emma's eyes widen at the teacher's blunt question. "Um...I'm not sure. It's...I mean..." She looks down at the floor. "Of course I'm scared of getting pregnant," she admits in a whisper. "What girl wouldn't be? This....my whole life is going to be affected by this, and I...I mean, Jack seems like a really nice person, but we don't know each other at all. And...and now we're making a kid together? It's so surreal and terrifying, and I'm so, so afraid of having to raise the baby alone because I don't know if I can give it up for adoption."

Jack feels a wave of guilt wash over him as Emma speaks about her fears. He hadn't even considered the possibility getting her or anyone else pregnant until now and the reality of it is overwhelming. He looks at her, wanting to reassure her, but he's not sure what to say.

"One final question, Emma, before we move on. Do you find Jack physically attractive?"

The question catches her off guard, and she blushes even harder. "Um...I...I mean, he's...he's not bad-looking. I guess." She looks down at her lap, feeling even more embarrassed now.

"Do you think he's handsome?"

Emma glances up at Jack, her cheeks flushing even deeper. "Yeah," she admits quietly. "He's...he's very handsome. And kind." She takes a deep breath, feeling herself grow even more aroused despite her fears. "But...but it's not just that. It's...it's like we're connected, you know? I feel like we could...we could be good together, despite everything, if that...." her voice hitches. "If that's what he wants."

Jack listens to her words carefully as he struggles with a maelstrom of his own emotions. He's honored that she thinks he's handsome, and he's touched by her admission that they could be good together. But he also understands the fear and uncertainty that she's feeling, and he knows there's only one thing he can do about it: man up and take responsibility.

"Emma," he begins, "I...I think we both feel scared and overwhelmed right now. And it's normal to feel that way. But I want you to know that...that I'm not just going to abandon you after, um..." His face reddens. "After we do it. I'll do my best to take care of you."

That gest another wave of surprise murmurs from the class. Emma's eyes widen, and even the teacher looks surprised. "Jack," he says carefully, "Are you saying you want to be involved with Emma and the baby? You are not obligated to do so by anyone, not me or the school. Think very carefully about this, it is not something you can just take back and it would be cruel to get Emma's hopes up only to change your mind later. Are you sure?"

Emma can't hide the raw, wild hope on her face as she waits for Jack's answer.

"Yes," he says, meeting her gaze. His voice is soft, but there's a determination in his words that makes it clear he means every word. "Trust me, I understand the seriousness of this situation and I'm not making this decision lightly. But...yeah. The more I think about it, the more I want to be involved all the way. It's true that we don't know each other well, but I want to be there for both her and the child. I want to support her through this, and be a part of our child's life she's okay with it. How can I look at myself in the mirror if I do otherwise?"

Emma nearly collapses with relief and throws her arms around him. She's crying again, but this time they are tears of relief, not tears of sadness and humiliation. "Of course I want that," she says, her voice ragged with raw emotion. "Thank you, Jack, thank you so much, you have no idea how much this means to me!"

"How sweet," Johnson says, rolling his eyes.

Jack returns Emma's hug eagerly. He's relieved that she's happy, but he's also nervous about what's to come. Still, he can't help but feel a sense of purpose and determination rising within him, a desire to protect her that is purely and fundamentally male.

As they compose themselves, the teacher clears his throat, indicating that they should continue with the lesson. "Now that we're all on the same page, we must continue with the lesson," says Mr. Johnson. "Jack, it is unfair that you are the only naked right now. Emma undressed you,, so now you may undress her. Please begin."

Jack hesitates for a moment, taking in the nervous glances from his classmates, but then nods and begins unbuttoning Emma's blouse. His fingers brush against her skin, sending shivers down her spine. She bites her lip, trying to keep herself from moaning at the sensation.

Jack looks back at Emma, feeling a new wave of nerves. He's never undressed anyone before, let alone a girl he likes. "Um...sure," he says, his voice a little shaky. He reaches out to unbutton her blouse, trying to focus on the task at hand. His fingers brush against her skin, sending a tingle up his spine.

Emma closes her eyes, feeling a rush of heat to her face as Jack's begins to unbutton her blouse. It's such a small touch, but it feels so intimate. It falls to the floor, and then he struggles with her bra for a moment. The brief pause makes him cringe, but Emma reassures him. "It's okay, Jack," she whispers, her voice barely audible even to herself. "Keep going. You're doing great."

Finally, the bra comes off, revealing her naked breasts to the class. They're pert and perky B-cups with small red nipples, and there are more than a few appreciative mutterings from the other students. Jack can feel his heart racing as he looks at her, taking in the sight of a girl's bare chest for the first time. His fingers tremble slightly as he slides her uniform skirt to the floor. Emma is wearing plain white panties underneath.

Jack pauses again, looking up at her, his hands resting on her hips as he prepares to pull her underwear down. His look is questioning, as if to ask if he should continue. Emma realizes then that she has only to say the word, and Jack would take the expulsion rather than touch her against her will. Her heart does a little flip-flop in her chest. He really is a good person she thinks.

Slowly, Emma nods for him to continue.

Jack takes a deep breath, steadying his nerves, and slips her panties down her legs. Now she's completely naked in front of the class, and it feels both incredibly liberating and impossibly intimate. Jack can feel his heart pounding in his chest as he looks at her, his eyes tracing over every inch of her body. He's never felt this way about anyone before, and he knows that this moment, however surreal, is something he'll never forget. Emma's pussy is absolutely glorious, tight, and shaven and prettily pink.

Jack takes her hand in his. "Are you okay?" he asks, his voice barely a whisper.

Emma nods, feeling her cheeks flush even more. "Yeah," she says softly. "I'm...I think I'm okay. Or I will be. Thank you, Jack." She looks down at the floor, feeling self-conscious but also strangely safe with him. Even if the whole class is ogling, it's not so bad if Jack is there by her side. Was this the first stirring of love?

Jack is about to reply, but Mr. Johnson cuts him off. "Now, Emma," the teacher says. "I want you to touch and stimulate Jack the way he stimulated you. Jack, the same rules apply to you that applied to Emma. Tell her what feels good, where you would like her to touch you, and do not feel shy about showing Emma any pleasure you feel. If you like what she's doing, let her know. Once you are done, we will ask you a few questions."

Jack looks at the teacher, then back at Emma. He swallows hard, feeling a mix of excitement and nervousness. He's never been touched by a girl before, and the idea of Emma doing it is both exhilarating and terrifying. "Um... touch my... penis," he says in a strained tone. "And... stroke it... gently."

Emma nods, taking a deep breath. Her heart is racing as she reaches out, her fingers trembling slightly as they brush against Jack's erection. She's never touched one before, either, and she feels a rush of heat to her face as she begins to stroke him. "Is this okay?" she asks, her voice barely above a whisper.

Jack gasps, eyes closing tightly. "Yeah," he manages to croak. "That feels... amazing." He places a hand on the back of her head, gently guiding her as she continues to stroke him. She's surprisingly strong, and it's driving him wild. He wants to feel more, wants to touch her in return, but he's determined to focus on this for now. "Oh... Emma," he whispers, feeling himself getting closer and closer to the edge. "You're... you're doing such a good job."

Emma feels warmth rush through her at his praise and redoubles her efforts. She begins to stroke him harder and faster, her other hand gently cupping and massaging his balls with her other hand. She's never held a dick before, and Jack's is warm and ridged with veins.

Jack's breath comes in ragged gasps as he feels Emma's touch intensify. He closes his eyes, feeling the pleasure wash over him in waves. "Oh God," he whispers, his hips bucking wildly against her hand. "That feels so good, I can't--I'm gonna--"

"--I'm calling a halt," Johnson says abruptly. "We can't have you cumming too soon, Jack. Emma, it's clear Jack is enjoying your ministrations very much, but if you really want to help arouse him, you might try performing oral sex. Or, in layman's terms, a blowjob."

Emma looks up at the teacher, feeling a mix of confusion and embarrassment. "Um... I don't know how to do that, sir," she says, her voice trembling slightly. "I've never... you know."

"The best way to learn is by doing," Johnson replies. "Try it. What do you have to lose?"

Emma nods submissively. Taking a deep breath, she carefully kneels down in front of Jack. She hesitates for a moment, feeling the weight of his member in her hand, before slowly opening parting her lips and taking him into her mouth. The taste and feel of him sends a wave of heat coursing through her body, and she can feel herself growing wetter once again.

Jack lets out a long, shuddering groan as Emma begins to suck on him, her hand moving in sync with her mouth. He slides his hand through her hair, urging her to take more of him, and she obediently obliges. Her lips stretch as she takes him deeper, and he feels himself getting closer to the edge.

"Don't just suck on it. Try moving your head back and forth on his shaft too," Johnson instructs her. "Slowly, at first, then build up more speed. You might also use your tongue to tickle the tip of his cock at the same time."

Emma nods, her cheeks hollowing out as she begins to bob her head up and down on Jack's member. Her hand moves up and down as well, squeezing him with care. She hesitantly reaches out with her tongue, flicking it against the sensitive head of his penis. Jack's hips buck wildly, and he lets out a groan that's part pleasure and part agony. His hips, of their own accord, begin moving in time with each bobbing of Emma's head.

"Fuck," Jack gasps. "Emma, this is incredible!"

Emma moans around Jack's cock, her mouth moving faster and faster as she sucks and licks him. She can feel the head of his penis brush against the back of her throat, and she adjusts her angle to take him deeper.

"Careful," Johnson says. "Too much and you might trigger your gag reflex."

Emma is about to adjust accordingly, but suddenly, and without any warning whatsoever, Jack cries out. His thrusts become more erratic. His cock erupts like a pressurized hose, sending so much cum spewing into Emma's mouth that she starts to splutter and choke.

"Ah... Ah... Ah... Ah..." Jack gasps, his eyes rolled back in his head. "Ah... Ah... Ah..."

Emma can't stop coughing. She tries to swallow, but there's just too much of it, and quite a bit of his sticky white cum spills out of her mouth and drips from her chin in thick strands. Jack's expression goes from one of rapture to concern and he takes her by the arm, helping her to her feet.

"Are you all right?" he asks worriedly.

Emma nods, her cheeks still flushed from the exertion and embarrassment. "Y-yes, I'm fine," she manages to say, her voice still a little hoarse. "I'm just... surprised. I didn't expect...that there'd be so much. Was I, um, good?"

"You did great," Jack assures her, his voice thick with emotion. "Really, Emma. That was incredible. I've never felt anything like it." He reaches out and cups her face gently in his hands, his thumbs tracing her cheekbones. "Thank you," he whispers, his eyes locked on hers.

"You did quite well for a first-time," Johnson says, handing Emma a tissue so she can clean herself. "But there are other ways to stimulate a male as well. Emma, why don't you try a nice kiss?

Emma hesitates for a moment before taking Jack's hand and leading him closer. She looks into his eyes, her heart racing, and leans in. Their lips meet in a gentle, tentative kiss. She whimpers, and Jack responds with a soft groan. He places his hands on her waist, drawing her even closer.

"Moving on," Johnson says. "I know things are getting steamy between you two, but we'll take a brief intermission here to explain male reproductive anatomy, using Jack here as a visual aid. Jack, please come and stand here, where everyone can see you."

Jack blushes and moves to stand in front of the class.

"Now, the most important parts to remember are the testicles," says Johnson. "Which produce sperm and testosterone, and the penis, which, well, you just what it's like in action. The scrotum is the sac that holds the testicles, and it's important to keep them cool, because heat can damage sperm. The perineum is the area between the base of the penis and the anus, and it helps support the penis during sex."

Jack nods, feeling a little self-conscious standing there in front of the class. He glances over at Emma, who is watching him intently, a small smile playing on her lips. He tries to focus on the lesson, but it's hard when all he can think about is how good it felt to be inside her just a moment ago.

"Now, let's talk about male arousal," Johnson continues. "As you can see, Jack here has a fully erect penis. This means that his body is ready for sexual activity. When a man becomes aroused, blood flows into the penis, making it stiff and hard." The class giggles, and Jack feels a blush creep up his neck. "It's perfectly natural," Johnson reassures them. "And it's something that all of you will encounter in your lives, whether you're male or female."

Jack tries to focus on the lesson, but he can't help but feel a bit self-conscious. He glances over at Emma again, wondering what she's thinking about all of this. Her expression is a mix of curiosity and amusement, and it makes him feel a little less awkward.

"So, what do you think, class?" asks Johnson. "Any questions about male anatomy?" A few of the girls giggle and whisper to each other, but no one seems to have any questions for Jack. "Well, in that case, let's move on to female anatomy next. "Emma, please get up on this table here and spread your legs wide to give us a good view."

Emma hesitates for a moment, feeling a mixture of embarrassment and excitement. That makes no logical sense, since after blowing Jack in front of everyone she was long past the point of modesty. Still, she takes a deep breath and climbs up onto the table, spreading her legs as she's told. "So," she says, trying to sound casual, "what exactly do you want me to do?"

"Just stay like that and hold still for us," Johnson says. "Now this, class, is the vagina. Note, first, and foremost, the wetness in and around it. This is a clear sign of Emma's sexual arousal and attraction to Jack, but it also a natural lubricant produced to help with male penetration into her body. Note also the clitoris, located her. It is unique in that it is the only organ designed specifically for sexual pleasure--it is filled with nerve endings and is very sensitive. Finally, I want to point out the labia, just here, and a special treat: the hymen. See that little ring at Emma's entrance. This is proof that she is a virgin. The hymen is torn away when a woman has sex for the first time, which is why it was sometimes called the maidenhead in the past."

The class seems to be hanging on every word, their eyes glued to Emma's body. Jack feels a mixture of arousal and jealousy as he looks at her. He wishes they were alone, so he could touch her, taste her, feel her around him. He can see she's as embarrassed as he felt when he was the one being examined a moment ago, so he takes her hand in his own and gives it a gentle squeeze.

Emma looks down at their joined hands, her cheeks flushing even deeper, and squeezes back. It's a small gesture, but it means a lot to her. She clears her throat, trying to focus on what Mr. Johnson is saying, but it's hard with Jack's hand in hers.

The teacher talks for only a few more minutes, pointing out the location of Emma's ovaries and womb, before saying, "Now comes the most important part of this lesson, where we will see everything we've covered put to practical use. Jack and Emma are going to demonstrate sex and human reproduction for us, and we will follow Emma's pregnancy as it develops."

Emma's heart skips a beat at this, feeling a mixture of shock, embarrassment, and excitement. She glances at Jack, who seems to be just as surprised as she is. The teacher continues, "Now, I want you to position yourselves so that we can all see what you're doing. Remember, this is for educational purposes, so give it your all.”

They exchange a quick glance before Johnson continues. "Why don't you two start with clit play? Jack, go over to Emma where she lies on the table and take her clitoris between your thumb and forefinger. Squeeze and massage it very, very gently and see how she reacts."

Jack moves closer to the table, kneeling between Emma's spread legs. His heart is pounding, but he tries to focus on what he's doing. He takes her clit in his hand, feeling the softness and warmth of her. He begins to massage it, as the teacher instructed, using just enough pressure to make her gasp.

Emma's body tenses, and she lets out a sharp breath. The sensation is incredible, and she can feel her desire building. Her breathing quickens, her heart thuds in her chest. She looks down at Jack, their faces mere inches apart, and his touch makes her feel so exposed and vulnerable. But in a good way. She wants more. She knows she shouldn't but she does. She's still frightened and feels vulnerable and exposed, but not as much as she did earlier. Jack makes her feel protected and safe.

She reaches out, taking his shaft in her hand and guiding it toward her entrance. Jack stiffens but doesn't resist or try to pull away. Emma whimpers as she feels his tip brushing against her slick, wet folds.

"Are you sure?" Jack asks hoarsely.

She nods. "Y-yes. I...I think it's okay if it's with you. Just...be gentle with me, okay?" She looks up at him with trusting, vulnerable eyes.

Jack swallows hard, his heart pounding in his chest. He's never done this before, never been in this position. But he knows he wants this, more than anything. He pushes forward, slowly guiding his shaft into her.

Emma stiffens and cries out in pain as her tight, virginal cunt struggles to adjust to the sudden intrusion. It hurts. She's shocked by just how much it hurts, and she clutches at him, whimpering. Jack immediately stops pushing and bends his head to kiss her, trying to take her mind away from the discomfort.

Her body slowly begins to relax, the pain easing into a dull ache. Jack senses this and pushes again, only to have Emma stiffen again. Once more he pauses, letting her pussy adapt and mold itself around his cock. It goes like this for several minutes, with Jack slowly penetrating her deeper and deeper, until finally his cock is buried inside her gorgeous body all the way up to the hilt. Her tightness and wet heat engulf him and it feels absolutely glorious.

Carefully, cautiously, he begins to move his hips. Jack watches Emma's face carefully as he does so. It's still painful, but to Emma's surprise, the pain starts to fade, replaced by a growing sense of pleasure unlike any she's experienced before. She arches her back, rolling her own hips to meet his thrusts, and moans.

Their bodies are slick with sweat and her juices as they move together. Jack can feel his control slipping, his need to just lose himself in this moment. He speeds up, thrusting harder and deeper into her, and Emma cries out in ecstasy, her nails digging into his back. Her hymen is torn away, stripping her of her virginity forever, but she doesn't care. The whole class watches with wide eyes as the two teenagers start going at it with gusto.

Jack lowers his head to suckle at Emma's nipples, teasing and caressing them with his tongue as he pounds her fertile body. Emma runs her fingers through his hair to urge him on. She wonders, briefly, what her boobs will look like once Jack has impregnated her and they begin to grow heavy with milk. She wonders what their child will look like when she nurses it.

"Jack," she says in a strained voice. "I'm glad it was you, I'm glad you're the one doing this to me!"

He groans, his hips pumping faster. "Me too, Emma," he manages. 'I...I'm so sorry it had to be like this, but I'm so glad you're mine now!"

"Yes," she says, reaching up to caress his cheek. "I'm yours forever, we're--oh, God!--we're gonna be good parents and we'll get--oh, fuck, right there!--we'll get through the challenges together! Our..." She chokes, both with pleasure and from the depth of her burgeoning feelings. "Our baby is going to be beautiful!"

Spurred on by her words, Jack's thrusts become even faster and harder, his body tensing as he feels the first waves of climax building within him. He can feel Emma's body tensing in response, her inner muscles gripping and massaging his cock, rippling and moving as if possessed of a will of their own.

Emma reaches a shuddering, heart-stopping orgasm first, her whole body tensing, her back arching like a bowstring. The veins in her neck bulge and a raw, guttural shriek tears from somewhere in the back of her throat. Colored spots burst in her vision and a wave of pure ecstasy washes over like an ocean current. She lets it carry her away, drowning in it, as her world flies apart and the world goes staticky and gray.

Jack follows her over the edge a second later. His thrusts grow more erratic, his breath is knocked from his lungs by the sheer, unbridled force of his orgasm. His cock throbs and then explodes, squirting jet after jet of virile cum deep into Emma's waiting, willing, unprotected womb. It is the most glorious, most incredible thing he's ever experienced. Masturbation has absolutely nothing on this!

He shudders and groans, his body shaking as he empties himself into her, filling her up, giving her his heart as he gives her his seed. Then he collapses on top of her, utterly spent.

The room is silent, save for their harsh breathing as the new couple tries to catch their breath.

Emma lays there, feeling warm and full. Jack is still inside her, his weight pressing her into the desk, and she can feel his softening member twitching inside her. She wiggles beneath him, enjoying the sensation. She can't believe that this just happened. It is so wrong, but it feels so right.

She looks up at Jack, his chest heaving against her breasts. His eyes are closed, and his face is flushed. She reaches up and tenderly wipes the sweat from his brow. "I think I love you," she whispers.

Jack's eyes snap open. Her words hit him like a truck, and he realizes that he's starting to feel the same way.

"Emma," he whispers, "I think I do too."

Their intimate moment is interrupted by the sound of their teacher, Mr. Johnson. “I hate to break such a romantic atmosphere, but we do have a lesson to conclude. Jack, please pull your cock out of Emma’s body so we can see her fertilization.”

Jack groans, reluctantly pulling his cock out of Emma. A thick stream of cum flows out, landing on the table between them. It's thick and sticky and tinged pink from the blood of Emma's ruptured hymen.

Mr. Johnson grins. "Yes, you’ve definitely been well-seeded, Emma. Good job, both of you.” He turns to the rest of the class. “And that, everyone, is the act of human procreation and sexual intercourse. Do not think, however, that this was simply a free sex show. There will be a test, and we will continue to follow Emma and Jack as her pregnancy progresses. Jack and Emma, your homework is to keep having sex on a regular basis, at least once a day. I want you both to keep a log detailing when you do it, how you do it and where you do it, and I will review this log at the beginning of each class to make certain you are staying on task.”

Emma blushes crimson, embarrassed by the teacher's words but also grateful that he's not making a big deal out of their intimate moment. She glances at Jack, noticing that he's still hard, and she can't help but feel a surge of desire.

"Mr. Johnson," she says bashfully. "I-I have a question. If Jack and I have sex every day, will that increase the chances of having a boy or a girl?"

Mr. Johnson chuckles. "I'm afraid it doesn't quite work that way, Emma. The gender of the baby is determined by the X and Y chromosomes, which are randomly distributed. Having sex once a day or even every hour wouldn't change that. However, it would certainly improve your chances of becoming pregnant if you aren't already.” The bell rings and he grins. "Class dismissed.”

As the class files out and Mr. Johnson leaves for the teacher's lounge, Jack and Emma are left alone. Jack reaches for Emma, pulling her close once more. "I can't believe we're going to be doing this," he whispers, his lips brushing against her ear. "I've always wondered what it would be like to have a baby with someone I love."

"Me too," Emma says, resting her face against his bare chest. "And now I know. W-will you come home with me after school? I'd like you to be there for me when...when I tell my parents about all this."

Jack nods, his heart racing at the thought of meeting her parents. "Of course, I'll be there for you. No matter what." He kisses her forehead, then stands up, helping her to her feet. "Let's get dressed, okay? We don't want to be late for our next classes. I'll come and find you though, I promise. We'll spend lunch together, and after we tell your parents, you can move in with me. I'll start looking for jobs so I can support you."

Emma smiles up at him, her eyes shining with tears of joy. "I love you, Jack."

He kisses her one last time, and she knows then that no matter what the future holds, she and Jack will face it together.

Maybe, just maybe, Mr. Johnson's class is the best thing to ever happen to her.
