# Chapter 4

Ms. Katie Callahan thought about the morning so far. She’d had her pussy licked by her students, she’d sucked off her coworker – Mr. David Francis – in front of them, the taste of his cum still lingering in her mouth, and now it was time to begin the first practical exercise of the class for the students. Her own pussy ached for an orgasm, but that would have to wait for a short while. She’d get her chance to have Mr. Francis between her legs before long. But now it was time for the girls to get their practice.

*Christine/Thomas*

Ms. Callahan answered a few more questions and then smiled at the first girl in the front row, Christine, and asked her to come forward.

Christine was fairly cute for her age, not the hottest girl in class but certainly attractive in a girl-next-door sort of way. Straight blonde hair and green eyes and a petite build, yet still sporting a nicely rounded buttocks.

“Perfect, now if you would kneel or squat in front of Thomas on the yoga mat and remove your shirt, in case he chooses to ejaculate onto your breasts.”

“Do I have to take it off?” the young girl asked timidly, shy about the smallness of her breasts but not wanting to state it outright.

“That is part of the exercise.”

Reluctantly she knelt down and slipped her t-shirt off, then unbuttoned and slipped off her bra to reveal her perky little breasts. Thomas stood nervously in front of the girl, looking down at her now naked chest.

“Now just reach up and begin stroking his penis.” Ms. Callahan prompted.

With one hand the young girl reached up and took hold of the penis in front of her. Thomas grunted with pleasure as she did so.

Gently she ran her hand along it a few times and then timidly leaned forward and kissed the tip of her classmate’s cock. She kissed it a few more times, moving down the shaft, kissing his balls, and then kissed her way back up the shaft, leaving one hand on his balls. When she reached the head once again the opened her mouth and inserted the boy’s cock inside. Immediately she felt Thomas’ balls contract, his cock jerk, and then felt a thick warm liquid shoot onto the back of her tongue. Before she realized what was going on another shot was sent into her mouth.

Trying not to gag she pulled her head back. Thomas’ cock slipped out of her mouth and sent a third shot squarely onto the teen’s now-closed lips. The final two shots both formed a streak from her cheek to her forehead.

With his knees weak Thomas began to stumble but was caught by Ms. Callahan, who leaned him back against her desk, penis still out but slowly softening.

As the girl knelt on the floor, her eyes closed due to her face being covered in cum and her mouth full of it, Ms. Callahan continued the lesson. “As you can see class, when Thomas was aroused his penis had become hard to better deposit its load. It’s goal had been to penetrate Christine’s vagina and cum inside, but we didn’t let it get quite that far. Now that it thinks it has done its job it’s getting soft again, and will stay that way until Thomas’ refractory period has ended, the refractory period being the time it takes for a man to be able to become aroused again after ejaculating. Remember that, it will be on the test.”

Turning to Christine she continued, “As we can also see, Christine has done her job well.” Ms. Callahan reached down and with her index finger pushed Thomas’ cum off her eyelid, wiping it off on the girl’s one clean cheek. “There we go, now you can open your eyes.”

Christine opened her eyes slowly and looked up at the boy who’s cum now filled her mouth, and then up at her teacher.

“You have two options now, you can either swallow or spit.” Ms. Callahan noted.

Feeling an unseen pressure to do as her teacher had done she mustered her strength and began to swallow the semen in her mouth. A small bit caught in the back causing her to cough, at which point the semen on her lips slipped into her mouth. When her coughing stopped the young teen girl slowly pushed her tongue out and licked the cum from around her lips.

“Very good.” Ms. Callahan said smiling, “You two may now take your seats.”

Thomas wobbled back to his desk, penis still out but now fully soft, and sat down. Christine stood and picked up her top and walked back to her own desk behind Thomas’. Lydia leaned over from the desk beside her and whispered, “You’ve still got jizz on your face.” Suddenly remembering Christine took her shirt and began to wipe the cum from her face.

Watching the two kids explore their sexuality for the first time turned Mr. Francis on more than he had expected, and as he stood to the side he could feel his own refractory period beginning to end.

“Next group.” Said Ms. Callahan once Thomas and Christine had returned to their seats.

*Brianna/James*

James walked to the front of the classroom with Brianna following close behind. As James stood Brianna removed her shirt and bra in one smooth motion allowing her naturally tanned and well-developed breasts to fall free, squatted down in front of her fellow student, undid his shorts and slipped them down along with his boxers. Within moments they were in position and without needing the slightest urging the young girl took hold of the penis before her and began to go to town. She stroked, licked, and kissed the boy’s cock, gave it few short sucks, and then in one swift movement she opened her lips wide, took hold of his cock, and sent his cockhead into her throat. Her nose rubbed against his pubic hair and the tip of her tongue touched against his balls.

As her lips tightened around the base of his cock the class looked in amazement. Her gag reflex was nonexistent. James looked down at his cock fully engulfed in the girls mouth, felt her tongue and throat muscles clench against the entire length of it. It was heavenly.

The hispanic girl held her classmate’s cock in her throat for what seemed like a whole minute and then began sliding it in and out. She started off slowly but gradually sped up until she was virtually facefucking herself with the boys cock. As she felt him start to cum she drove home one last time as deeply as she could and just as her lips reached his base she felt his cock begin to spasm. The boy’s cum completely bypassed the teen’s mouth and went straight down her throat. As James continue to orgasm he attempted to pull back, wanting to get a few shots on her face or breast, but she grabbed his asscheeks and pulled him close, keeping him fully implanted in her throat until his last spasm finished.

As the last stream of cum went down her throat Brianna kept her lips around the base of the cock. She kept suckling on the gradually softening cock, her eyes locked on the boys and her hands kneading his ass and lightly moaning to herself through his dick. James’ cock naturally got shorter as it softened and was soon too short to reach into the cute brunette’s throat, but she continued sucking on it nonetheless, refusing to let it get fully soft.

From the perspective of Ms. Callahan and the rest of the class it was unclear just what was actually happening. It seemed as if James had orgasmed straight down the young girl’s throat, but this would have normally been the point when the girl would pull back and stand up. Ms. Callahan wasn’t even positive the boy had orgasmed, though he certainly looked like it. With Brianna’s lips sealed around the base of his cock there was no way to tell for sure how far along they were. Perhaps he had started to orgasm but held back.

James stood there in total bliss, the wave of sensation from his orgasm beginning to subside, but his cock still fully locked inside the hot girl’s mouth, her tongue still running along his softening shaft, her mouth still providing suction, swirling his dick around her mouth. ‘This girl really loves to suck dick’ he thought to himself as he enjoyed the continued feel of her mouth while looking down into her dark brown eyes which seemed to smile up at him.

Brianna did in fact enjoy sucking dick, or at least, she took pride in making men feel good and had found that her deep-throating abilities were excellent at doing so. She felt as if she needed the approval of men, and providing such mind-blowing sex was her way of gaining that approval. Her therapist had told her that it was her way of coping with certain indecent actions by her no absent father, and while she felt some mild level of repressed shame over it she also felt a paradoxical need of living up to that standard, as if each cock she sucked seemed to her a way of gaining that approval in some way.

And so she kept her hands on the boy’s ass and kept his crotch pulled tight to her face, his cock buried deep in her gullet. With her movements the penis was never able to get fully soft, and after a full five minutes of continued suction she could feel it getting gradually harder once again.

As he reached full erection yet again James took the lead this time, feeling he knew what the girl wanted. Placing his hands on the back of her head he began rhythmically pulling her head towards his crotch while simultaneously pumping forward with his hips. She smiled up at him – as much as a girl can with a cock fully lodged in her mouth – and began to help his rhythm by pulling his ass in unison with the pumps of his hips.

“How is she doing that? What’s going on Ms. Callahan?” one of the girls asked with her mouth agape at the scene.

“It’s called deepthroating, Brianna must not have a gag reflex, which allows her to take James’ entire penis into her mouth at once, so far that the head of his penis ends up in her throat.”

His head rolled back as he was fully facefucking his young classmate, occasionally looking down to enjoy the sight. Her eyes had begun to water and saliva was now running down her lips and chin, coating his balls as they slapped against it. The class watched aghast as the boy’s cock would withdraw till only the head was left inside her mouth and then the whole length of the shaft would ram home once again. With one final drive he pulled the girl’s face fully against his crotch and held her there as a second load of cum poured down her throat and directly into her stomach. His entire body shook at the sensation and his legs finally gave way. As he crumpled to his knees his cock finally popped out of the girls mouth, a final string of cum hitting her lips and dropping onto her breasts as he did so.

Both teens sat on the floor taking deep heaving breaths, James from exhilaration and Brianna from having had a cock in her throat for the past ten minutes. The teens smiled at each other in their exhaustion. Brianna got up and gave him a wet kiss on lips as she returned to her seat. James’ managed to find his legs and returned to his own seat as well, the rest of the class still staring dumbfounded at the pair and what they had just witnessed.

*Annalee/Rick*

Annalee and Rick came up next. Rick stood and the young Christian girl knelt in front of him. She had long straight blonde hair and wore a long flowery skirt and a buttoned-up blouse. Shyly, knowing what she had to do, she began undoing the buttons. Once unbuttoned she kept her shirt on but open and unclasped her bra, allowing it to fall off her breasts.

She took a deep breath and looked up at Rick, whose eyes were transfixed on her luscious chest until he felt her fingers on his waistband. She slipped her finger inside the band but didn’t pull down, and Rick reached down to help, slowly pushing his shorts and boxers down to free his cock. Annalee looked so innocent with her face next to it, just sitting there looking at it in a sort of trance, working up the nerve to touch it, trying not to think of how wrong it was.

Sensing her reluctance Rick took his cock in his hand and pointed it down towards the young Christian’s mouth, running the head over her lips. As the cockhead touched her lips she snapped out of her trance and reached up to wrap her hand around it. Sticking out her tongue she traced a line from the base of his cock to the head, repeating the pattern a few times over before working up the courage to place the flat of her tongue on the bottom of his cockhead, open her mouth, and guide his penis inside and simply began to suck as if his dick were a lolly-pop.

Annalee looked up into her classmate’s eyes as she sucked. She massaged his balls and then began to slowly bob his cock in and out of her mouth. The skin on the head was much smoother and softer than she’d expected, and the shaft much firmer.

‘Maybe it’s not that bad’, she thought to herself, ‘I mean, if we started dating and got married eventually, then he’d still be the only person I’d have been with, and that would make it ok, wouldn’t it…’

Her thoughts were suddenly interrupted as Rick groaned “I’m about to cum.” Annalee opened her mouth and waited for his cum like she’d seen Christine and Ms. Callahan do, giving his shaft a few smooth pumps using her saliva as lubrication and then it came, a shot across her face, a second and a third onto her tongue, and a final one aimed down, glancing off her chin to hit her breasts. The taste of the cum was unpleasant, and thinking that maybe it was less sinful not to swallow she pushed the cum out, flooding down her chin and dripping down to join the final shot on her breasts.

Rick started back to his seat, but before Annalee could get up Alan, one of the boys who didn’t have a set female partner, raised his hand, “Ms. Callahan, I’d like to go with Annalee too.”

“That’s quite fine.” Ms. Callahan replied before Annalee herself had a chance to respond.

*Annalee/Alan*

The young Christian knelt there, cum still dribbling down her chin onto her breasts, as Alan stepped up in front of her and pulled his cock out of his pants. He was the outspoken agnostic of the class, and she’d try to evangelize him more than once, telling him that he need to turn away from his sins and have faith in their creator. And now here she was, kneeling with cum on her face and his cock directed at her mouth, the second one she was about to suck today, indeed, the second one in her life. Whatever excuses she had made the first time, she knew this time would be sinful.

She scowled up at the boy in front of her, ‘Why did he have to choose her of all people’ she thought, looking at the erect cock in front of her. Finally she resolved herself to the task, if her maker in his providence had put her in this situation, then it must have been for the best, or so she reasoned. ‘Perhaps this will somehow be used to convert him away from his agnosticism.’

With this reasoning providing her with some reassurance, she reached forward – slightly less hesitantly than the first time – and guided the shaft toward her mouth, sliding the tip of her little pink tongue along the bottom length of it, from balls to tip, then back down again. Back and forth, up and down, her young, sweet mouth and tongue caressed the length of his prick. Alan looked down and marveled at what the sexy young Christian girl was doing to him.

He could tell she was learning fast because, after another minute, she tilted his stiff shaft down with her left hand and, when she got to the head, opened her lips and slid her classmate’s erection into her sweet, wet fucking mouth. As she sucked Alan ran his hands through the girl’s hair, placing one hand behind her head to provide a sort of rhythm. Of all the girls in the class whose throats he wanted to cum down, Annalee’s was the one he wanted the most, to put her in her place for all that nonsense she believed, always acting better than everybody else.

“Mmmm… God, you’re good,” he said ironically, his voice half moaning with the intense pleasure the young girl was creating between his legs. Annalee’s lips closed tightly around his shaft and he could feel her tongue move over and around the head, licking at the sensitive tip. Her mouth again closed over the tip, sliding the length deeper into her mouth.

Alan put his hands on the sides of her sweet Christian face, guiding the movement of her head, showing how to stimulate his prick with her mouth. What he couldn’t show her was the action of her tongue as she licked and sucked his shaft. She seemed to know how to do that naturally. Up and down her head bobbed, her hand now slipping up and down in time with her mouth, skimming lightly over the skin of his cock. He stood above her and watched, admiring the incredibly sex view of this pretty, holier-than-thou teenage girl on her knees in front of him, his cock slowly moving in and out of her young mouth.

Gradually Alan used his hands and hips to push ever-so-much-further past her lips. He smiled as she looked up into his face with his cock deep in her mouth. Remembering how she had avoided swallowing Rick’s cum it was at this point he chose to release his pent up ecstasy.

With her lips wrapped around her classmate’s shaft, her tongue rubbing along its underside and his cockhead at the back of her throat, Annalee felt Alan’s fingers tighten on the sides of her head and then without warning felt a shot of hot slick cum hit the back of her throat and slide down her gullet. She tried to pull back as another load filled her mouth, but his hands kept her from fully disengaging. Her eyes went wide and she looked up at him as he gave a delight-filled smile as yet another and another pump of his cum emptied into her mouth. Almost on instinct of trying to breath with liquid in her mouth she accidentally swallowed another portion before managing to push the rest out, coating her lips and joining Rick’s cum on her chin and breasts.

“Jesus Christ that was great,” Alan said doing his best to sound blasphemous, his dick finally free of his classmate’s mouth.

“Very good Annalee.” Ms. Callahan remarked as Annalee stood up, “You rose to the occasion very well.”

Annalee, finally able to return to her desk, began wiping the cum off of her. That had definitely not gone as she had planned, but if her actions were used for some greater good then she was content, or at least it gave her something to tell herself.

*Randi/Jason*

When it was their turn Jason and Randi walked up to the front of the class with some hesitation. Jason was hesitant at having to live up to the show they’d all just seen. Randi was nervous at having to suck on a penis, to taste a male’s cum, and to have it on her body, three thoughts which didn’t appeal to her in the least.

He helped her remove her shirt, revealing a small but shapely pair of breasts. She reached up and undid his pants, letting them fall to the ground, and knelt, mortified by the bulge in the boxers just in front her face.

“Now Randi, just remove his boxers, and repeat what we’ve demonstrated so far.” Ms. Callahan advised.

Randi looked up at her teacher and then once again at the bulge and slowly pulled the boxers obscuring her view down. She flinched backward as the cock sprung to attention in front of her, almost hitting her face. Reluctantly she reached out and rubbed her hand along his dick, stroking it, and then leaned forward and touched her tongue to it as she began to slowly pump her hand up and down its shaft. Finally she parted her soft lips and unenthusiastically inserted the cock into her mouth and began to suck. It was so weird, this knob that she had in her mouth. How could girls like this? She pointedly avoiding licking his balls. The dick was on thing, but those weird looking bags were too much.

Thankfully for her this was Jason’s first blowjob, and the very thought of a hot teenage lesbian sucking on his cock sent him over the edge rather quickly, somehow the fact that he knew she wasn’t particularly enjoying it made it all the hotter for him. He’d always thought Randi was hot, but had given up any chance of ever being with her. How many guys could say they’d had a legit hot lesbian suck them off? It was all too much.

“I’m about to cum… I’m about to cum… open your mouth and let me cum on your face…” he said, thinking of the many pornos he’d watched.

The lesbian teen closed her eyes and opened her mouth as she continued to pump on the boy’s cock, dreading what was to follow. She felt the shaft in her hand swell just as it began to orgasm, but was still startled and flinched and the first stream of cum which suddenly struck her lips and trailed all the way up to her forehead. The second and the third hit likewise, but the final stream Jason intentionally aimed at the girl’s open mouth, hitting her bottom lip and continuing in to coat her tongue and glancing against the back of her throat. As the cum slipped down her throat she began to cough, pushing what cum didn’t make it down her throat back out of her mouth to dribble down her chin and trail down her neck to her breasts. She was frozen in a mixture of shock and disgust.

Jason reached down and began to rub his cock across her face, wiping the streaks of cum on her face downward off her nose and lip and into her mouth. She was still too petrified to move as he pulled her mouth back onto his cock and pushed in till its head was on her tongue, then used his thumb and forefinger to push the remaining cum out of his shaft, dribbling it onto the lesbian teen’s tongue.

As he withdrew a final time Randi picked up her shirt, wiped the cum from her face and body, and spat the cum in her mouth into the trashcan, hoping that she would never have to touch a penis again.

*Bryn/Bryan*

“Help her take her shirt off,” Ms. Callahan instructed Bryan. While the two seemed open to the idea of oral sex, it still wasn’t a very natural thing for a sister to suck her brother’s cock, the teacher thought as she watched the pair of siblings.

Bryan unbuttoned the front of Bryn’s shirt and she shrugged it off her shoulders and it slid to the floor. The girl was a little small for her age, but she had slender, girlish body with well formed curves and breasts that had developed nicely.

After a moment Bryn raised her hands, unsnapped the snap on her brother’s jeans, and slowly, grudgingly, pulled down the zipper. When his pants were open, the young girl pulled his jeans down over his hips and they fell to his feet.

Bryan just stood there in the class, now wearing just his blue cotton boxers, his barely hardening cock creating a small bulge in the front. Finally, Bryn reached up with both her hands and gently ran her fingers up and down over his small bulge. Bryan hissed through his teeth at the sudden onset of physical sensation between his legs as his little sister stroked his cock through the cotton material of his underwear. The siblings locked eyes and after a few seconds she tucked her fingers under the elastic waistband and pulled his briefs over his cock and down his legs where they joined his jeans in a pool at his feet. Instinctively Bryan turned his head away. His penis was still mostly soft with only the slightest hint of hardening, the nerves, the embarrassment, and that fact that it was his sister blocking his ability to become erect.

“Now, don’t worry about not being fully erect Bryan, once your sister begins it should become firmer.” Ms. Callahan said reassuringly, noticing his nerves. “Bryn, just begin by taking it in your hands, and once you’re comfortable you can place your brother’s penis in your mouth.” Just saying the words gave her warm feelings in her abdomen, the thought of vocally encouraging the sibling incest before her.

Bryn made herself more comfortable on her knees in front of her brother and simply stared for a moment at his semi-soft penis. This was going to be her first real taste of penis, her brother’s in front of her class. She gathered her will power and gently ran her hands over the sides of his dick.

Starting at the red tip and moving down underneath his balls, her thumbs caressed the soft underside of his penis while her fingertips played along the head. The boy’s breath hissed in and out between his teeth as his little sister knelt on the floor in front of him and massaged his lightly pulsing cock. After several passes up and down over the entire length of his prick with her hands, the teen girl adjusted it slightly with her fingers, brought her head forward, extended her tongue, and ran it along the length of his still fairly soft cock.

“Oh, God…” came the sound from Bryan at the first warm, wet contact of his little sister’s tongue on his cockhead. Each time she held his shaft at the base and washed her tongue around the head of his cock she gazed up at her brother’s face, and each time she noticed that he became ever-so-slightly harder in her mouth.

As her saliva gradually coated her brother’s cock she began skimming both of her hands over it, still not moving very fast, and while his sister’s tongue continued to run along his shaft Bryan looked down at her. With each run of her tongue his cock became slightly harder.

As he became semi-erect Bryn took her brother’s cock with her fingers at the base and inserted the smooth shaft into her mouth. Concentrating she began to apply suction to her brother’s cock, allowing it to slip in and out between the ring of her tightened mouth. At first, she took about half of the hardening length into her mouth several times. She paused each time the boy’s cockhead popped out of her mouth to lick around the tip with her little pink tongue before slipping her brother’s velvety hardness between her lips again.

The class watched transfixed in a mesmerized stare as they watched the smooth, shiny, glistening surface of Bryan’s cock move slowly in and out of his little sister’s mouth, a mixture of distaste and concupiscence. Boys and girls in the class who before now had never thought about their siblings sexually suddenly began to wonder how it would be to have their own sister sucking on their dick or to be sucking on their own brother.

Bryan glanced down once again and watched the sight of his younger sister kneeling before him, his dick sealed within her lips, her eyes closed as she focused intently on bringing pleasure to his genitals. Just then he realized that he was now fully erect; his sister had successfully brought his body to arousal. His mind was still another thing, even with his cock hard in his sister’s mouth his brain still told him that it was wrong, and he was convinced that he would go soft if she let off for a moment. Giving in slightly to the pleasure Bryan’s head began moving side to side quietly moaning, his eyes closed, as he started to allow himself to enjoy the total sensation of his sister’s wet, sucking mouth on his prick. Occasionally, when he’d open his eyes and look down at his little sister and see the sexy thing she was doing to him, a louder groan came from his lips, and he would move his hips slightly back and forth almost as if he was fucking her cute face.

Bryn could tell her brother was gradually getting more and more into what she was doing, and not only because her mouth was now filled with a fully hard cock. His hip movements, his groans, and the fact that he was staring down at her more and more often all revealed the fact.

The fact that she had managed to get her brother aroused also made her feel mixed emotions of accomplishment and distaste. How could she kneel here and suck her own brother’s cock. Gathering her willpower once more she resolved that if she was going to do it she was going to do it well. With her free hand she began rubbing her brother’s inner thigh, working it up to his balls to massage them as her head bobbed and his cock moved in and out of her mouth.

The sensations were all too much for Bryan and he felt his sperm welling up in his balls. His body suddenly went rigid as he climaxed, and he seemed to hold his breath as his hips jerked with each powerful spurt. A muffled grunt came from his throat as the spasms sent shocks of intense pleasure up from his loins and rippling throughout his body.

Bryn was caught off guard from the thick warm liquid suddenly filling her mouth. One spurt, another, then another. She tried to pull back but her brother placed his hand on the back of her head and held her in place as he continued to shoot his seed into her mouth.

When he had finished he held himself completely still, his hands gripping his sister’s shoulders to keep from collapsing onto the floor as his orgasm overwhelmed him. After a minute he seemed to relax as his climax subsided, and he again looked down at his little sister.

Bryn still held the tip of his cock between her lips, seemingly reluctant to release her brother’s softened cock from her mouth. In truth she was just still a little surprised at it all. It was all just educational of course, but her brain and body and conscience were sending her mixed signals. Bryan’s white cream dribbled out the side of her lips as she struggled to keep all her brother’s cum within. With his cock still in her mouth she finally swallowed the load he had deposited. She pulled her head back and her brother’s prick slipped out of her mouth with a final slurp. The siblings eyes met and each quickly darted their gaze away and moved back to their seats.

The other students were caught between being amazed, disgusted, and turned on by what they’d just seen, as were the teachers. ‘Well, I guess we’ve crossed that bridge now.’ Mr. Francis thought. He had been fearing the siblings would provide more resistance, but they’d followed through like champs.

‘I can’t believe we did that’ Bryan thought to himself, ‘And I… enjoyed it, that was definitely sinful. Why did I cum in her mouth? She’s my sister. I could have cum somewhere else. I didn’t have to fill her mouth. Maybe it was just instinct. I can’t control instinct. But why did she swallow it? Well at least it’s over. We can move on.’

‘It’s an interesting taste’ Bryn considered as she sat down, ‘And like Ms. Callahan said, it’s just a cock, it’s just cum… even if he is my brother…’

The rest of the class filed through with their partners, or multiple partners. The busty redhead Stephanie swallowed Scott’s cum like a champ, the petite asian Katelyn – a foreign exchange student from Japan – had gotten her first faceful of American jizz from Robert, and both Seth and Philip had the honor of having the lovely ebony teen Emma suck their cocks.

Philip had been assigned to join in with Emma, though he wished it had been Christine. He couldn’t complain about Emma though. She was kinda nerdy with glasses, but pretty with a toned body. She fumbled around with his cock abit, clearly lacking familiarity, but when she finally took him min her mouth he came fast for her, to his own displeasure. Seth chose Emma because he’d always wanted to be with a black girl, and when it was done he loved the way his cum stood out on her face against her smooth ebony skin.

*Kevin/Ms. Callahan*

At last Ms. Callahan announced, “Alright, that only leaves Kevin. Who would you like to join you today?”

“Ummm…” he said hoping for a miracle, “I was hoping you could Ms. Callahan.”

Ms. Callahan was slightly caught off guard, “Really, these exercises are meant for you all as a class.” The plan had been for them to each touch her briefly, and for her actual sexual actions to be limited to Mr. Francis. The idea that she might perform on her students, suck one of their cocks and swallow their cum, had not yet occurred to her.

“Yea but what difference does it make, everybody else has gone. Besides, I’d rather have an expert do it.” He added smiling in hopes of buttering her up.

Ms. Callahan stood for a moment pondering before conceding, “Very well, I suppose that will work.” ‘After all why not’ she thought, ‘It makes no practical difference.’ Plus she had to admit the thought of being with a student was at least a little arousing.

Some final second guesses arose as her student walked forward, but she knelt down anyway. He stood proudly looking out at his other friends in the corner, about to have his cock gobbled by their hot teacher.

Ms. Callahan looked up at Kevin’s face, reached forward and pulled down his shorts and boxers in one swift motion. His cock was only partially erect, still slightly soft, as she ran her hand along it, took it between her fingers, and began running her tongue from his balls to his cockhead.

Kevin groaned as his young teacher finally took his cock fully into her mouth, sucking and rubbing her tongue along its silky underside. He ran his hands through her hair and felt one of her hands moving down to massage his balls, while the other jacked his cock.

Wanting him to get the most from the experience Ms. Callahan pushed her student down into the instructor’s chair near the desk. She took her place between his legs and continued sucking his cock, but he was slightly disappointed when she popped it out of her mouth and began licking down his shaft. She continued down till she was sucking on his balls, one hand still jacking his cock.

Just when he thought she was about to work her way back up Kevin felt the young teacher go down even further, prompting him to instinctively raise up.

Ms. Callahan had forgotten to demonstrate analingus on a male when she had done the demonstration with Mr. Francis, so she figured she would make up for it now, going lower until her tongue flicking across her student’s anus. Kevin was in heaven.

Ms. Callahan broke the heaven for moment to address the class, “As you can see, massaging the anus with your tongue can also be extremely pleasurable for the male.” And then she returned, jacking his cock and licking his anus.

“Where would you like to cum?” Ms. Callahan asked as she finally detached herself from her student’s anus, still jacking his cock, “On my face?” she said winking and rubbing his cock across her cheek, “or maybe in my mouth?” she continued, placing the tip of his cock on her bottom lip.

“I want both, I want to cum on your face, and I want you to swallow it from my cock.”

“Very well, it would be my pleasure to drink your cum Kevin, I want to drink it straight from your cock and swallow it.” she said as she licked and stroked his dick. During the instruction portion of the class and with Mr. Francis she tried to keep her vocabulary clinical, to talk of penises and vaginas and ejaculation, but while actually involved in the act she chose to use terminology that would help produce the desired effect. “I want your cum on my face and in my mouth, c’mon, give me your cum Kevin, I want to eat it so bad.”

Finally his teacher’s words pushed him over the edge. She could feel him about to burst and aimed the first shot squarely between her eyes, glancing up to her forehead and running down her nose, a second shot hit her upper lip and nose again, and then she had it in her mouth, sucking as the third and fourth shot filled her mouth with her student’s spunk, “Aaawwww yeaa, take it… take it…” Kevin managed to say through his orgasm.

She used her fingers to milk every last drop of cum from his cock then opened her mouth to show him. Kevin gazed down at his cum covered teacher as she swirled his cum in her mouth, then she gave him a wink and downed the load. “Sooo tasty” she said, and he watched as she slowly wiped the rest of his cum from her face and down into her mouth, swallowing it in turn, “I just love eating your cum Kevin.”

Ms. Callahan gave her student’s cock a final kiss on the tip and stood up. Kevin, beaming with pride but spent from his orgasm, made his way back to his desk.

“Now class, why was I talking like I was with Kevin?”

“Because it’s hot.” Alan said confidently. A few other students laughed or echoed a hearty “Hell yea it was.”

“Exactly. Dirty talk can be a great way to arouse your partner even further and push them to climax, so if you feel comfortable feel free to try it during the class. And now that the girls have had their practice at fellatio, we’ll move on to giving the boys some practice at cunnilingus.”
