## Chapter 7

“As I was saying,” Ms. Callahan continued, “the main form of safe sex that we’ll be practicing today is anal sex.”

“Now, what are some of the things you’ve all heard about anal sex?” she asked.

“That it’s dirty.” Annalee said.

“That it hurts.” Stephanie added.

“That boys just want it because of porn, but girls won’t like it.” Thomas chimed in.

“Good. Now all rumors have a hint of truth, and it is true that if you don’t prepare properly it can be messy and painful, and because of that girls often don’t enjoy it. But we’ve prepared properly already. This was the main purpose of the enemas this morning.”

The young teacher bent over her desk, ass to her students, allowing Mr. Francis to take over the instruction.

“And it’s not just because of porn that boys like it. A woman’s butt is one of the key sexual features males notice, so it’s only natural that they would want to put their penis in it. I’m sure all the boys here would agree that Ms. Callahan’s butt is quite appealing.” he said giving one of her cheeks a light slap.

Echoes of “hell yea” reverberated throughout the classroom.

“What’s more,” he continued, “in times when the only options for avoiding pregnancy were pulling out or anal sex, anal sex is the less risky option. So in older societies men might start in the woman’s vagina, and once he was sufficiently lubed with her juices switch up to her anus. Simple. Safe. And mostly effective.”

“Is that why God designed them so close together?” Annalee asked curiously.

“If you want to think of it that way, sure.” Mr. Francis responded warmly.

“So, moving on,” he continued, “I mentioned lubrication, and as you can see we have this bottle of oil here. Most cooking oils will do, though they make synthetic oils that are even slicker. If you don’t have any oils then remember your saliva can do the trick in the pinch, which is why it’s always helpful to start a bout of anal sex with some analingus.”

Ms. Callahan reached back and spread her cheeks for her coworker and bounced her butt up and down a few times in excitement, “Yea, give my ass a good lick Mr. Francis.” she said sweetly.

Needing no more encouragement Mr. Francis moved forward and began to passionately attack his coworker’s backside with his tongue, probing as deeply as he could past her sphincter as she relaxed to allow him entry.

“Oh yea, the students just love watching you with your tongue up my ass.” she said looking over her shoulder and smiling at them.

“Fuck yea, eat that hot ass.” Kevin chimed in, knowing he would be doing so himself in just a short while.

Mr. Francis pressed into her sumptuous hole with his tongue while his hand when to work on her pussy, until finally he gave his young coworker a few more deep licks and then reluctantly dislodged himself from between her asscheeks.

“Now,” he said turning to the class, “If you’ll watch I’m going to properly lube up Ms. Callahan’s ass.” He guessed since she had broken with the academic jargon he might as well too.

He took the bottle and poured a dab out onto his fingers and then slowly worked it into up into Ms. Callahan’s asshole. One finger, two fingers, in and out coating her anus in the slick oil, her anal ring clinging tightly around them as he worked a rythm with them. It was so tight around his fingers that even with the lube he could hardly believe he was about to slide his cock in there.

Pulling his fingers out he took the excess and coated his own now rock hard cock.

“Now to show you how to properly fuck a woman’s ass.” he said smiling as he turned.

He raised Ms. Callahan up onto the desk on all fours and then climbed up behind her; he was thankful it was a large desk, otherwise it would have made for a difficult balancing act, and this was one of the best ways to make sure the students had an ideal view.

Straddling his coworker’s perfect globes he aimed his rod down at her little rosebud. She wiggled her ass at him flirtatiously.

‘Finally here,’ Ms. Callahan thought, ‘About to have my ass fucked for the first time, about to have my anal cherry popped in front of a bunch of students.’

She breathed deeply in preparation, ‘Am I really up for this?… Yes… I’ve got this… I can do this…’ she reminded herself as her coworker mounted himself onto her, as he pushed the tip of his cock down against her waiting hole. She relaxed her ass muscles and he slipped in with a pop past her sphincter.

‘Oh! It’s in!’ she thought with glee, wiggling her ass back at him again, ‘I’ve done it!’

A few students gasped as they watched his cock disappear into their teacher’s rectum. He looked down, he was already halfway in!

She felt her connection with her partner build. He had been just a friend, a coworker, but now, she’d shared *everything* with him. Did that make them something more, or was it all just professional? It was professional, but still, she let herself slip away.

“Oh yea, fill my ass David. Fill my naughty little ass with your hard cock…” she said seductively as he pushed in to the hilt.

Balls-deep in her sweet ass he stopped, taking the moment to provide some instruction, “Now, why have I stopped moving once fully inside Katie’s… I mean Ms. Callahan’s anus?”

“To enjoy the feel?” Seth asked.

“That’s one reason, any others?”

Ms. Callahan clenched and unclenched her asshole around his cock, prepping for the pounding she was about to receive as the students answered.

“To get her used to it and loosened up so you can slam that ass!” Brianna said confidently.

“Correct.” Mr. Francis laughed, “While savoring her asshole is certainly nice, stopping like this also gives her time to get used to the feeling. Now that I’ve given her a moment, the proper assfucking can begin.”

Placing his hands down on her hips he began to slide in and out of his coworker’s young slick hole, her asshole muscle gripping his rod as he plunged her soft rectum.

“One thing you’ll find is that while nearly a woman’s whole vaginal canal has muscles that will contract around your cock, her ass has mainly just one, the asshole itself, and the way it grips your cock will be your main form of pleasure.”

With that he continued plunging her sweet hole. He looked down and watched his dick slide in and out between her cheeks, then leaned forward and kissed her.

“Fuck my ass just like that David… Fuck it… good… Fuck it… hard…” the young teacher said between breaths.

“Shit I love your ass Katie…” Mr. Francis responded, “I love your ass so much… you’re… soo… damn… sexy….” he said as he slammed between her asscheeks.

“Keep slamming my ass… fuck my fine ass till you cum…” she said, “I bet your wife never let you cum up her ass before… but mine’s all yours… C’mon! Dump that married cum up my ass!”

He kept pounding her young hole, not sure why she got so turned on reminding him about his wife – was she just one of those girls who got off knowing she was fucking another girl’s man?

Either way it was working. He felt the pressure building up in his balls and began to cum with a deep “Fuuucckkkk….” emitting from his throat. He kept pumping as he sent shot after shot deep into his coworker’s bowels.

“Yessss…. deeep inn my assss.” she said in return.

Finally he popped out and Ms. Callahan flipped around under him, he instinctively dropped to his knees straddling her chest and leaned back as she took his slick cock into her mouth.

“Fuck yes I love the taste of my ass on your cock.” she said looking up at him, her eyes filled with desire. Her ass was clean enough that the only thing should could really taste was oil and cum, but still, it sounded hot, and that’s what was important.

Mr. Francis dipped his softening cock in and out of her mouth before finally collapsing down to the side, exhausted.

*Brianna/James*

When it was their turn Brianna and James came to the front.

Brianna laid down on her back and put the cushion under her lower back, lifting her ass up off the ground and spreading her legs wide, “You’re doing the work this time.” she said, “Now come here and fuck my sweet little ass.”

“Damn straight I’ll fuck that ass.” James said moving down toward, diving his face into her pussy briefly and then moving down to her asshole.

“Yea eat that ass.” she said as she put her hand on his hand and pulled him tightly between her cheeks.

James just couldn’t get enough of it, tonguing her little hole, hoping he’d get the chance again even after this class was over. How would relationships between the class go forward after this? Would they just have casual sex? Would it go back to how it was, just fondly remembering this hot session? What were the logistics of moving forward?

‘Questions for another time,’ he thought as Brianna pushed against him, driving his tongue deeper into her hole.

Finally she released him and he grabbed some oil and slipped a finger in, working the oil into the teen’s tanned hispanic ass, past her dark brown sphincter.

As he fingered her ass he leaned down and kissed her, dove his tongue into her mouth and felt her tongue enter his.

Finger still in her ass and tongue still in her mouth James shifted forward and dipped his cock down into her pussy. He pumped in one, two, three, four times and then pulled out and aligned with her asshole.

She winked her asshole at him as she smiled, “It wants you. My tight little ass wants your cock deep inside.” she said wrapping her legs around behind him and pulling him closer, pulling his cockhead up against her ass, still pulling until he sunk in.

“Awwwww yeeessssss…” she said deeply, “Fuck me hard, just fuck me now.”

With little hesitation James began pumping in and out of her sweet soft ass, bracing himself on her breasts as he did while she reached down to rub her clit.

Her asshole welcomed him easily, and James could easily tell she’d done this before. He groaned as the hot hispanic teen clenched and unclenched her ass with each of his strokes, milking his cock with her asshole.

As she rubbed her clit he reached down to finger her slit, bracing himself with just one arm as he continued plowing in and out of her wanton fuckhole.

“I want your… cum… up my… ass!” she yelled loudly between pumps, “Give me… that… hot… cumm!”

Leaning forward with his face in her breasts and hands wrapped around on her asscheeks now James began driving as hard as he could. Having cum twice today it was taking some time, not that he minded, every second spent in Brianna’s ravishing ass was bliss.

He pumped and kept pumping into her firm latino ass until his legs were weary. He didn’t realize fucking could be so tiring. Brianna seemed to be able to tell and spurned him on.

“Don’t you stop now… don’t you be a little bitch…” she said forcefully through his thrusts as he slowed down, “Keep fucking me… keep slamming my ass till you cum… harder… harder!!!”

Steeling his resolve James kept on. He was nearing exhaustion when he felt his balls finally swell. One. Two. Three more thrusts and they exploded, pouring his load down deep into her hole.

With only part of his load dropped in her ass he pulled out with a slurping ‘pop’ and followed Mr. Francis’s lead, slipping down and resting his ass on Brianna’s breasts, feeding his cock down to her mouth which she willingly took in. Even more, she grabbed his ass and pulled him tight until he was buried to the hilt and his balls were resting on her chin and there she kept him until he was spent.

This was definitely her favorite position to be in, on the floor with a cock balls-deep in her throat. For her, this was heaven. For her, this was fulfilling her deepest longings. For her nothing made her feel more at home.

She moaned deeply through his cock, savoring the feel of it, the balls on her chin, the hairs on her nose, the throbbing shaft against her tongue, and the head down deep where she could feel a few final bits of cum leaking from its tip down her throat.

“Damn you love having that cock down your throat.” he said breathlessly through the pleasure as she held him close. Her eyes smiled up at him through his pubic hair and she smacked his ass with both hands as she held him there, her throat contracting around his shaft.

Eventually he softened, and eventually Brianna released his cock from her gullet, much to both of their displeasure.

*Annalee/Rick/Alan*

Annalee came forward. This had been the last thing she had expected to have to do today. Before this morning she would have never understood how it could have been appealing. The Bible forbid it afterall, right? But it had felt so nice to have her ass licked, to have it fingered, and licking those fingers afterward gave her this weird feeling of forbidden arousal.

Maybe it not being allowed in the Bible was just a cultural thing? You know, since they didn’t have soap and enemas and stuff. Either way, she was about to do it.

‘How should I start?’ she wondered, ‘Maybe hands and knees? That seems easy…’

Rick came up just as Annalee had gotten down into the doggystyle position, her scrumptious ass calling out to him, the teen’s pink little hole winking at him as she tried to work on relaxing it in preparation.

“Would you lick my booty please.” she said trying to practice her dirty talk and wiggling her butt like she’d seen Ms. Callahan do.

“Hell yes I’ll lick that booty…” he said mimicking her choice of words.

He knelt down behind her soft white globes, clapping a hand down onto each and massaging them deeply before spreading her cheeks and diving in with his tongue.

Annalee giggled and wiggled her ass back against his face as he licked her hole, allowing herself to give in fully to the pleasure, and it was only too soon when his tongue was replaced with oiled fingers probing in, pressing past her tight little hole and exploring her rectum.

Fully lubed Rick spread some oil on his cock and when ready straddled the blonde Christian’s hips on his knees. Gently he pushed his cock down through the crack of her ass to the small, tight anal opening.

“Annalee, put your hands back and spread your cheeks like before. That’ll make it easier for Rick,” Ms. Callahan suggested as she watched them.

Rick’s cockhead pushed firmly at the opening. It opened and took the tip almost right away, his cockhead popping past her sphincter with a sigh from both students.

With the head firmly inside, he let go of his cock and put his hands on the cute blonde’s curvy hips. Pushing his hips forward slowly but firmly he drilled his cock into the teenage Christian’s asshole, his shaft disappearing between the cheeks of her ass and up into her butt.

Rick began to slowly thrust his cock in and out of the girl’s behind, the warm tightness was paradise. The puckered anal opening seemed to suck at his cock seeking to draw the spunk out of his shaft. He closed his eyes and groaned at the sensation.

“Mmmm… that’s gooodd… bang my ass, Rick… Oh, God, make me cummmm…” she said as he pushed into her, and now she was pushing back against him, pushing back with force. During one particularly hard push back she knocked him off balance and he grabbed her waist for support only to pull her back on top of him.

Rick sat with the hot teen in his lap, cock still buried in her ass, and then she began to bounce. Up and down and up and down on his rod she rode him, him reaching around to massage her breasts as she did.

He watched as he cock slid in and out of that perfect butt, her long blonde hair flying in his face during each upstroke and falling back on the downstroke, and on one particular downstroke he took hold of her hips and held her there as he began to squirt his cum up into her ass.

He fell back in the bliss of his orgasm. Alan was already there standing by, and Rick sighed as the hot Christian ass slipped off his cock as she pulled Alan down. She had been on the verge of climaxing when Rick finished and in the heat of this moment she didn’t want to lose that momentum, didn’t want to lose all of that built up pleasure.

Before he even had time to get up she had straddled Alan and drove her ass down onto his cock, resuming her thrusting as if she hadn’t even changed partners, his own cum no doubt providing the lubricant.

By the look on his face Alan was just as surprised as Rick.

Even though his cum-covered cock was still standing proud Annalee leaned back over, enclosing her lips around his shaft, licking his cum off as she continued thrusting down onto Alan.

The development certainly caught the teachers off guard, but they saw now logical reason to intervene. The precedent had been well set by Emma after all.

The fact that the hot little Christian was pleasuring both of them turned Alan on all the more. ‘So much for those morals,’ he thought to himself, ‘all that gets you is all this pent up sexual energy.’ And boy did she seem to have pent up sexual energy.

The cute teen bounced up and down on top of him, impaling herself on his cock while she continued to suck off Philip, but soon she tired and slowed. Alan shifted, moved her back onto all fours, and mounted himself behind her.

Putting his hands around her thin waist he re-positioned at her beautiful butthole and thrust down into her once again.

Harder and harder their bodies came together and soon all three were lost in a haze of intense sexual pleasure, the once innocent Christian being anally split-roast by two of her classmates.

Moving his hands around to her buttocks Alan began to give her ass light smacks, “You’re a bad little Christian girl, taking two cocks at once.” he said to her.

Popping the gradually softening cock out of her mouth she responded without even looking down at him, her eyes closed, “Yea, I’m a bad girl… forgive me Lord… yea, spank me… pound my butt… oh yeaa… pound my ass…”

Alan gave her ass another series of whops as she took Rick’s cock back in her mouth.

Even though Rick still wasn’t able to get hard again yet the awesomeness of his situation made him put his hands on the girls head and start humping her face, his balls slapping her chin, his pubic hair brushing her nose – normally she would have choked, but with his cock semi-hard it only partially filled her mouth and he could feel her tongue push out to skim against his balls.

Alan continued pounding the girl’s ass from behind. He admired the look of her sucking his classmate’s cock, he admired the curves over her body, the smooth skin of her back and the trail of her spine, and then the heart-shaped ass at the bottom with its little pink hole that clung tightly around his cock.

As he slammed the girl’s ass Alan wondered whether he could press his luck, and gave Rick a sort of circling symbol with his hand. Realizing what he was doing Rick popped his cock out of the girl’s mouth just as Alan popped it out of her ass; Annalee felt distinctly empty for a moment as the two moved around and as a cock returned to her lips without thinking she opened her mouth and let it inside. Meanwhile a much less rigid cock slipped back into her butt.

Alan looked down at her as she sucked his cock, “Yea, does that taste good?”

Annalee merely moaned in response.

“Yea, you like the taste of your ass don’t you.” It was now his turn to hump the young girl’s face, his hands on either side of her head pulling her to him as he drove his cock inward, her eyes looking up at him with a mixture of desire and melancholy.

She was finally broken, he thought to himself. Mission successful. Basking in his success he let the girl suck his cock of her own accord. “I’m gonna go finish in your ass.” he said as he pulled his cock out of her mouth.

“Yea, cum in my ass! Do it!” she said heatily as Alan moved. She felt her asshole go cold as Rick pulled out and came around.

“Yea, come here, I wanna taste my ass. Let me taste my asshole off your cock.” she said giving in fully. She took him into her mouth once again.

She felt Alan re-enter her ass as she sucked on the cock in her mouth, slamming into her backside now at full speed, reaching down and playing with her clit.

After a few more pumps Alan was finally ready “God, I’m cumming,” he said through clenched teeth, the tension building in his balls, “I’m gonna cum in your sweet, fucking Christian ass. Oh, fuck, I’m gonna shoot…”

For the final time he pulled her back into himself hard and held her ass tightly on his shooting cock. His hands held her tightly around her waist as spurt after spurt sprayed up into the slender girl.

“Oh God, finnaalllyy.. Oh… ffuuuuckk… ” she said as something inside her was driven over the edge.

She ground her ass hard back onto his cock for the last time, twisting and turning, whimpering in a small voice as her face grimaced in pleasure, still giving a slight suckle to the cock in front of her.

Annalee reeled in the aura of her orgasm, of the two cocks that she had, of the class and her teachers looking on, never expecting to see her act so filthy.

The cock in her ass slipped out and she felt the cool air enter her gaping hole. Next thing she new Alan’s cock was back in her face. She took it gladly, suckling the cum juices off of it, her eyes smiling up at the two boys in front of her.

*Randi/Jason/Mr. Francis*

Once the trio had returned to their seats Randi walked reluctantly up to the front of the class with Jason. As the other girls had she got down on all fours on the yoga mat and spread her asscheeks, her adorable butt raised in the air.

Jason gladly moved down behind her and dove his face between her cheeks. At least in this position she could still pretend he were a girl, that it was her crush’s tongue pushing in past her sphincter, her crush’s tongue exploring her holes.

Giving her hole a final kiss Jason took the bottle of lubricant worked it with his finger onto the girl’s anus, holding his cock in his other hand, still only semi-hard.

He pushed the lube as deep as he could with one finger, but she was still super tight, and that just around his one finger – how was he supposed to get his cock in there?!

Still, he had to try. Rising up behind her Randi felt the cockhead touch her anus and froze up. Noticing the resistance Jason rubbed more lubrication onto her tight asshole and pushed his cock against it but it was like a wall, and his still partially soft cock merely bent against it.

“It’s too tight,” Jason said to Ms. Callahan.

“You have to push out, like we said.” the teacher said to Randi.

“Sorry Ms. Callahan…” replied the lesbian. She took a few breaths and then pushed her anus, and felt the cock once again pushing against it, yet still to no avail.

“I’m afraid you’re too soft.” Ms. Callahan observed moving closer, “Try sucking on him once again Randi.” The cute lesbian reluctantly spun around and took the boy’s semi-hard cock in her mouth and began sucking. Jason tried to concentrate, to will an erection, but after two minutes of sucking the cock she had made no progress.

“I’m afraid your penis has reached its refractory period yet Jason. Normally it’s much faster for one your age, but everybody is different.” Ms. Callahan said, “Mr. Francis, I believe you’ll have to help out. If you could loosen her up a bit while she keeps working on Jason’s penis it might work.”

Mr. David Francis’ cock had returned to full erection since he’d cum up his coworker’s ass just a short while earlier (he had made sure to take the proper supplements this morning). Still, he hadn’t expected this. But why not? Katie had fucked Kevin, why shouldn’t he get his turn with a student?

With Jason’s dick still in her mouth Mr. Francis got down behind the young blonde lesbian.

‘Now I have to take him too?’ she thought to herself, but still dutifully reached back and spread her asscheeks once again, waiting for what was to come, trying to tune everything out.

“She probably needs more arousal as well.” Ms. Callahan noted as knelt down next to her coworker. Just as she hadn’t began the day planning on sucking off and getting fucked by one of her students, neither had she planned on eating out one of the girls.

Rather than the cockhead she expected Randi instead felt something soft. At first she thought it was Mr. Francis’ tongue, but then she realized the cheeks brushing against her skin lacked his scruff, and she looked back to see Ms. Callahan’s face buried in her crotch.

She licked up and down her student’s pussy, stopping to focus especially on the clit. It was actually the first time she had ever tasted another girl, and she was surprised to find that tasting this young lesbian was beginning to turn her on. She worked her way gradually higher till she was licking the young girl’s ass, giving her own saliva as lubrication for her coworker.

Randi found herself finally getting truly aroused for the first time that day as her teacher ate out her pussy and ass, pushing her tongue inside, swirling it, then a finger, then two, slowly loosening up the young girl’s butt enough that it might take a grown man’s cock.

Ms. Callahan pulled back from her student’s backside and her coworker took his place behind the young lesbian once again. Reasoning that it would be best to distract the girl, she moved Jason to the side and lay in front of her student spread-eagle, positioning her cunt just in front of the young lesbian’s face.

Randi looked up at her teacher and her gaze was met with a warm, comforting smile, and then she felt her teacher’s hand on the back of her head, guiding her mouth to her waiting cunt.

Now fully aroused Randi dove into her teacher’s snatch, less focused on the cock that Mr. Francis was now rubbing along her crack.

When he went to bed last night he dreamt of how wonderful it was going to be fuck Ms. Katie Callahan’s ass and cum down her throat, but lining his cockhead at the sphincter of this petite young lesbian as she ate out his fellow teacher was a whole nother rush. The class too sat in awe as Randi was there on all fours in front of the class, a teacher on either end, one about to fuck her butt as she ate out the other.

Ms. Callahan’s fingers had loosened up the teen’s ass and her tongue turned her on enough that when Mr. Francis straddled the cute butt and began pushing the head of his cock against the girl’s sphincter.

The lesbian teen’s asshole opening for his cock, enveloping his cockhead, was the most beautiful thing he’d ever seen, rivaled only by the simultaneous sight of the teen’s face buried in his coworker’s cunt; by the look on her face she was clearly enjoying the teen’s tongue on her clit, hopefully as much as he was about to enjoy plunging her little butt.

With another push his cockhead popped past her ringed muscle.

Randi gave a slight whimper, muffled against her teacher’s pussylips.

Millimeter by millimeter he worked his cock deeper into the lesbian’s teenage rectum. When his balls finally came to a rest against her taint he stopped and simply savored the sight and feel of being buried in the tight lesbian’s butt, her sphincter contracting and releasing around the base of his dick as she tried to acclimate to a cock being balls-deep inside her ass.

Mr. Francis began to slowly pull back, once again millimeter by millimeter, until only the head of his cock remained within the grip of her tight ass muscle, and then he began to push in once again.

As Mr. Francis continued moving in-and-out of the lesbian’s teen ass Ms. Callahan tried to keep her focused on eating her out, running her hands through the girl’s hair and holding her mouth against her clit.

“That’s it, you’re doing great, just breathe, push out, and focus.” she said encouragingly.

The feeling in her ass was less painful than Randi had anticipated. For her it basically just felt like she was taking one long shit, yet the idea of a man fucking her butt was still unappealing.

Having her hot teacher’s cunt in her mouth, however, was highly appealing, and she was glad for the distraction. Still, every time her teacher began to push his cock into her once again Ms. Callahan could tell she was tensing up more than desirable.

“If you’ll just keep up what you’re doing Mr. Francis I’m going to adjust to provide Randi with some additional stimulation.” As she spoke Ms. Callahan turned and slip underneath her student to form a 69.

“Now if you would lower your hips just a little so that I can reach your clit I can provide stimulation while you continue focusing on me.”

With her male teacher still embedded in her ass Randi adjusted till she felt her female teacher’s tongue on her clit. The sensation sent welcome shivers through her and lowered her own head between Ms. Callahan’s legs, planting kisses on her clit.

She heard various gasps from the students in the class; it was a classic position for the porn they’d watched, but they never dreamed they’d see it in real life.

Ms. Callahan could taste the dried cum on the surface of Randi’s cunt from her fucking earlier, and every now and then some of the residual sperm would make its way down into her mouth from where it had resided deep in the girl’s pussyhole.

She licked through the soft folds of the girl’s pussy, circled around to her firm button, and focused there once again. Ms. Callahan didn’t really find herself attracted to girls, but savoring this young girl was pleasant, she had to admit.

Above her she watched her coworker’s cock slide in and out of the student’s lesbian ass only centimeters away from her face, his balls occasionally grazing against her nose.

She watched the cock go in and out, and could tell it had used up most of its lubrication.

When Mr. Francis had pulled out almost all the way once again Ms. Callahan reached up and popped his cockhead the rest of the way out of the girl’s ass, taking him off guard.

‘Why did she take me out?’ he thought to himself, until she guided his cock down to her mouth and began sucking and relubricating it with her own saliva.

After taking Mr. Francis’ cock deep in her gullet and covering it in her slit spit she guided his cock back into the lesbian’s teen ass.

Lubricated once again his thrusts became gradually faster and more forceful.

The idea of the young Ms. Katie Callahan sucking his cock straight from the student’s ass was too tempting for him not continue to take advantage of, and so every ten or so thrusts he would pull out fully and guide his cock down to her wanton mouth, admiring the teen’s gaping asshole as he did so.

Spitting some of his own saliva into her open hole he let his coworker give him a few more licks and then drove home once again, balls deep in the youngster’s ass.

He gave her a few more thrusts and then did what he knew he had to do, unfortunately. He withdrew and moved aside, motioning for Jason to take his place. This exercise was for Jason’s benefit afterall, he would be neglecting his teacherly duties if he didn’t let the boy fuck his classmate’s ass, afterall the boy might never get the chance to cum in a girl’s ass again, much less that a cute little lesbian like Randi.

The boy had been standing to the side and and slowly gotten his cock hard once again.

Jason got down behind his classmate, took in the sight of her gaping asshole, and looked down at Ms. Callahan’s face beneath. Taking his chances he pointed his cock down towards her and asked “Lubrication?”

Without a word Ms. Callahan reached and took his cock in her mouth, swirling it about and sucking till it was almost fully hard; here she was now, two students. The thought aroused her even more.

Mimicking Mr. Francis, Jason spit onto the girl’s anus, then guided his cock from his teacher’s mouth and into the waiting butthole. This time her asshole gave no resistance, but seemed to suck his cock into its silky warmth.

Jason grunted at the intense pleasure, put his hands on the girls hips and then began to thrust, in and out and in and out, occasionally remembering to occasionally return to Ms. Callahan’s mouth for more lubrication.

“As you can tell,” Mr. Francis said as the trio continued their fucking, “This is one of the ideal setups for a threesome involving two females and a male, and even though Jason is in Randi’s rectum now, the position would work just as well for conventional intercourse. Group sex such as this can be a great way for bonding between multiple friends.”

Jason was now slamming into Randi’s asshole at full pace, and Ms. Callahan went to work on her clit to make sure she associated anal with pleasure. In a sudden rush she successfully brought the blonde teen to climax.

Jason was startled as the girl who had his cock up her butt suddenly started spasming, her whole body shaking and her anal muscles clenching around his cock, sending him over the edge too, driving home one last time as his cock finally started spurting, sending jets of his cum deep into the lesbian’s teen ass.

He gave a few final thrusts and then withdrew.

His cock hung down and unbeknownst to him the last two minor spurts of his cum landed squarely on Ms. Callahan’s face, who was still busy licking the girl’s cunt as she came down from climax.

His gaze was transfixed on the gaping cum-filled hole in front of him, admiring his work till he felt a sudden warmth on his cum-coated cock as Ms. Callahan filled her mouth with him once again, sucking it clean. It had served no practical teaching purpose but she had done it without thinking, realizing as she did so that she had simply been hungry for more cock.

Jason slowly rose, and Randi sat up, still straddling her teacher’s face. As she tried to rise further she felt her teacher’s hands gently hold her there, and then felt them slowly part her asscheeks, a tongue exploring her gaping hole as it began to regain it’s normal size.

Taking the cue Randi reached down and spread her young cheeks further as she felt her teacher’s tongue work it’s way up into her asshole, as she felt Jason’s cum leaking out of her butt and into her teacher’s mouth.

Again Ms. Callahan had to admit it served no academic purpose, she just wanted to do it, and to help Randi enjoy this experience as much as possible.

Mr. Francis watched as his coworker locked her lips around the young girl’s anus and dove her tongue inside. Whenever her lips unlocked he could see the sperm dripping down into her mouth, her soft tongue guiding it to the back of her throat, and then swallowing it, only to return to the girl’s hole to suck more of the boy’s jizz out.

“Yea, lick my asshole Ms. Callahan…” Randi said closing her eyes and gyrating her hips, driving her asscheeks down around the young teacher’s face, “Suck that cum out of my butt… ooohh yeaa, right therrree…”

Randi still didn’t particularly like the idea of having a cock inside her, but the idea of cum leaking out of her into another woman’s mouth oddly turned her on. It was a dilemma she’d have to ponder.

Finally Randi dismounted her teacher, giving her a kiss on the lips as she did so. Their tongues locking ever so briefly.

It was the first time Randi had lived her dream of 69ing another girl, she felt as if she might be in love. She just wanted to go back to eating her teacher’s pussy for the rest of the day, but before she could Ms. Callahan began to rise as well.

Ms. Callahan too was surprised at how much she had enjoyed coupling with the young girl, going beyond clinical instruction to wantonness, wondering whether another side of her sexuality was opening up to her.

“So… yes… an excellent demonstration,” the teacher said once she was standing. “Uhhmmm… And as you saw, sometimes a female may need to be aroused and gradually loosened before full sex can occur, and this is true with both the anus and vagina.”

Randi took her seat, and Ms. Callahan called Bryn and Bryan forward.
