Finally it was another Friday. Roman had finished with his final physics class of the day, letting all the students lose minutes ago as he listened to the bell ring inside an empty classroom. Prior to a few months ago, he would have left with the students, eager to get home and get these clothes off of him.  Instead though, he stripped there in the classroom, setting the required teacher’s garments aside.  Right on cue, the door opened revealing the racoon freshmen girl he had become far too acquainted with.

“Hello again Keelay,” he said with a big grin. His normal classes were seniors, most of whom were trying to avoid the difficulties of pregnancy, so he rarely got to watch the progression of the freshmen girls after sex ed class. And the raccoon girl was definitely progressing, her belly bulge becoming quite noticeable, especially after shedding her hoodie once stepping foot inside the classroom. It was also strangely thrilling knowing that the baby growing inside was possibly his own. 

“Hi Mr. Roman,” she responded with a small giggle, excited for the short time they got to spend together. 

Roman did make an attempt to distance himself from his student at first, but the young racoon girl had no interest in distance, and it was far too easy for the older fox to succumb to his own urges rather than turn her away. Their coupling outside of class could become problematic for his continued employment - he was often picked to head sex ed class because of his professionality with the students, after all - but something about this racoon girl and her tenacity in pursuing him made things complicated. So he decided on a compromise, once school let out each Friday they would get together in class, a quick fling before the weekend. 

She wasted no time in climbing up into the fox’s lap. Her small but pronounced belly pressed right up against him, Roman could feel the warmth radiating off of her. Her naked form settled right into her usual spot, those puffed up pussy lips resting right against the fox’s plump sheath. For the last few months, this was generally how their meetings went, Keelay’s brash desire for sex led them to intimacy nearly immediately. He felt his tip starting to press just inside her, sinking just inside that familiar passage, but there were other things to discuss. 

“Did you do your homework this week?” Roman had challenged Keelay with a weekly assignment; she had to hook up with at least one boy her own age during the week if they were to mate each Friday. Roman still felt it was important for her to socialize with kids her own age, despite her clear tenacity for older men. 

“Yeeees, of course.  Yesterday after the third period.” 

“Oh? What was his name?” 

“Brian, a lizard boy. He’s kinda cute, he has a slit like other scalies, he never wears clothes either. He’s a few seats away from me, I always peek to see if he’s showing anything between his legs.”
Roman chucked at her rambling. To be young again…

“As long as you're still paying attention to class too.” Roman responded.

“Oh yeah, of course, I’m doing great in that class anyway. But yeah, yesterday he kept sneaking looks at his phone, and he was HARD under his desk, like leaky and all. Was trying to hide it but I know what to look for.”

By this time Keely had ground her mound in against her teacher’s crotch and managed to suff most of his cock snuggly up inside her. Thier coitus had become so casual between them that neither broke the conversation. 

“So we had quizzes to end the class,” Keelay continued,”and once you were done with the quiz you could leave. He finished his quick but like, wasn’t leaving his desk, and I knew why. I hadn’t done my uh...homework… yet, so I stuck around too. Once everything left, I totally just sat right down in his lap.” Keelay beamed with pride up to her teacher, loving her retelling of this story. But Roman was a little less amused.

“You did ask for permission first, right?” 

“I mean, yeah, pretty much…” she seemed a bit embarrassed, “ I asked ‘is this seat taken’ and he seemed a little confused, but then I pointed down at his crotch and he figured it out.  I dunno if he expected me to actually sit in his lap but he definitely didn't seem to mind!”

“And who teaches this class? Were they alright with your little escapade?” 

“Oh, yeah, that was Ms. Starry, she said as long as we finished up before next class we were fine.” 

Keelay all the whole was gently rocking those hips on her up and down Roman’s cock, he could feel her walls gripping his bare meat as it slid up and down inside her. It was a feeling he didn't think he would ever get used to, her slit seemed to fit his length just so perfectly. 

“And I assume you were able to do so?”

“Oh yeah,” the raccoon girl said with a smile, “He was sooo pent up, like he gave a huge gasp when I got his cock up in me, I don’t think he lasted more than a minute before he came. And he came BUCKETS too, it was sooo much I could feel it. I had to run to my next class too before cleaning up and it all leaked out on the chair, I was just sitting all in it the whole class! And it SMELLED like cum in the room. I was so embarrassed. I blame you and your homework assignment.”

Roman gave another chuckle. He would have loved to see this racoon girl actually embarrassed for once. Sitting in a pile of seed given to her from some random classmate, filling the room with the smell of sex.  Then again, he would probably have been too distracted to give a proper lesson anyway. 

“Well I’m glad you finished your homework at least”

“That means I get the knot, right?” Keelay grinned mischievously and pressed her hips down harder against her teacher’s groin, that inflated fox knot pushing right up against those lips.

“You will, sure, but not right away. I was hoping you might be willing to help me out a bit first,” said Roman, his paws keeping her hips from just pressing right down on his knot. “I know you’ve been asking to help out in the sex ed classes, and I figured this would be a good week to do it.  We were a bit mismatched on genders this week, only two girls to five boys, and two of the boys became very…possessive of their partners, despite my best efforts to separate them. So the other three boys weren’t able to actually mate with the opposite sex. Instead of pressuring the students I figured I would just invite them after class today to have a session with you, if that’s alright.” 

Keelay’s eyes lit up as she sported a devious smile back to her teacher. “FINALLY I get to be a teacher's assistant again. I’m totally down!”

“Good,” Roman responded, hooking his paws under her rump and starting to pull her back off his cock, ”they should be here any moment.”

Once he got her small frame high enough his cock slid right out, flopping against his belly. He could tell she seemed a bit heavier than last time, that belly of her’s definitely starting to add some weight. He set her down in front of the chair and she stood there, facing him.  

“I Imagine they will want to finish up their assignment quickly, being right before the weekend. They just need to mate with a girl in order to pass the class.”

“Ohhhh I gotcha,” She responded. She went to a nearby desk and leaned over it, lifting up her fluffy striped tail. Roman couldn’t help but take a long glance at that view, that pussy glistening with moisture, that pregnant belly hanging low between her legs. 

They both heard a small knock on the door, and slowly swung open to reveal a mouse boy, his frame even slighter than Keelay’s. He wore glasses and was fully clothed, like many of the more shy students at the school, and slipped right inside the door with barely a sound. He first looked at Roman, saw his naked figure and hard red cock between his legs and blushed profusely, but continued nonetheless.

“Hi Mr. Roman I came back like you s-” He stopped short when he glanced over at the raccoon’s rear end, seeing that wet pussy on full display.  Roman watched the kid’s eyes go wide at the sight, he started fidgeting in place.

“Hello Chance! I’d like to introduce you to Keelay, she went through sex ed several months ago and has volunteered to help you and the other two boys this week with completing all your assignments. As long as you attempt a mate that’s enough to get an A in the class.”

Roman wasn’t really sure if the kid was listening or not, he couldn’t peel his eyes off the display in front of him. Roman could already tell the kid was rock hard inside those pants, he figured this should be an easy session.

Just then the door opened again, and the other two boys came in together, a hare and an otter.  Both boys wore a tank top but were otherwise naked, going bottomless was a recent style among some boys at the school. They were chatting amongst themselves, but also stopped and stared once they saw the rear end of the racoon.  Keelay had started swaying her rump back and forth, enticing the other boys. Roman heard some hushed words like “woah” and “nice” coming from the two boys that just entered.

“Hello! As I was telling Chance, this is Keelay and she’ll be helping you three finish sex ed class.  In order to get an A you at least need to attempt to mate with a member of the opposite sex, and since our class was a little skewed this week Keelay offered to help.”

The two boys passed the bespeckled mouse and walked right up to Keelay, their excitement quickly becoming obvious as Roman watched their small sheaths plump up. 

“Feel free to use anything you’ve learned from the week. I won’t be grading any technique, but do enjoy yourselves and make sure Keelay enjoys herself.”

Both the boys look back up at each other, then back down at the racoon rump, then back at each other again. They seemed to be trying to silently figure out who would be going first, before finally the hare dropped down to his knees behind the girl. Roman watched as the hare pressed his nose against her slit, then gently pressed his tongue out against her. The warmth of his tongue was met with a happy moan from the racoon girl, egging on the hare to go a bit further. 

Keelay kept moaning as that hare lapped at her pussy, really pushing his tongue in there. His otter friend watched on, cock in paw slowly stroking his hard member.  The bunny boy stood back, wiping his mouth with the fur on his forearm, looking back over at his teacher. 
“That’s how you do that, right?” he asked.  

For a moment Roman thought he was just being sarcastic, but he remembered this batch of boys never got  the chance to have any contact with a girl all week, so his question was likely sincere. The three boys had been relegated largely to gay sex between themselves for the week. They all took to homosexual sex just fine, fortunately, and all three of them had the chance to bottom and top.  The mouse boy in particular seemed to enjoy bottoming for the other two quite a bit.

“Yes, that’s perfect Ronny, you have to do a little more to get A”s in the class though.”

“Yeah I know I’m getting to that…” he responded.  His own cock was rock hard, his paw easily wrapping around the smaller tapered penis. He looked down and tried pressing his hips forward, trying his best to aim towards the racoon girl in front of him. After a few moments of gentle stabbing and a frustrated look, Roman decided to walk up and offer some help. 

“Here, I’ll try to guide you in,” said the fox, reaching down and grabbing the kid’s cock between his thumb and forefinger.  It was tough to see exactly where to push in front his position, given that big tail flicking around, but Roman guided that cock right toward his pussy and with his other paw pressed’ the teen’s rump forward, feeling him sink right inside. That hare gave a soft “ohhhhhhh…” when he finally sank in, feeling the warmth of that passage around him for the first time. 

“There you go, feel free to continue,” Roman stepped back and watched as the kid quickly started to hump the girl in front of him. He gave soft, gentle thrusts that soon turned into quick, jutting stabs.  His paws instinctively grabbed Keelay’s hips as he kept thrusting. Keelay was moaning along with him, she seemed to be enjoying her role of assistant. The otter stood to the side watching close as his friend continued to hump away.  Each thrust the hare gave a small, cute squeak, slowly picking up speed faster and faster

After a few more moments, the hare gave out a few high pitched moans as he slammed his hips into the rump one last time. He stayed there a few more moments, breathing heavy, pumping a load of cum into the racoon girl. His breath was heavy, his eyes closed, his paws gripping Keelay’s fur tight as he unloaded. Finally the hare boy pulled back, slipping his softening cock out showing a pussy dripping drops of cum on the floor. 

The hare looked right over to his friend, the otter was masturbating the whole time and was eagerly awaiting his own turn. The hare conceded his spot and the otter stepped right up, and with a quick steadied motion slid his length right up inside Keelay.  Despite being about the same size, the otter teen didn’t seem to have any problems finding his mark.  Keelay gave out another moan as the otter got to work immediately, pounding his hips against the racoon at the same rhythm his friend had left off. Roman could hear the wet sloshing of the otter cock humping away at that used pussy.

It took the otter even less time to get over the edge, he gripped those hips tight and gave a moan similar to the hare, holding his hips close making sure to pump as much as he could inside his classmate. As he pulled out, even more cum fell to the floor below. He muttered “holy shit…” just under his breath, and his friend responded with a soft “I know, right?” 

Roman handed over a towel to the two boys, and they started wiping down their crotches as their cocks tucked back inside their sheaths. “Wonderful! As you could probably tell Keelay is already pregnant, so this isn’t quite a true mating, but it’s definitely enough to complete the course for you two. You’re free to go, enjoy the weekend!” 

The two boys laughed and chatted amongst themselves as they left the room quickly, trotting off to their weekend plans. Roman looked back and saw the mouse boy still standing off to the side, the front of those pants completely soaked through with pre as he watched his classmates finish the course.  

“Alright Chance, it’s your turn, go ahead and strip down for us again, we can get started.”

The shy mouse boy slowly started dropping his clothes, eventually just leaving his underwear.  He paused for a moment then dropped them too, showing a sizable cock underneath, much bigger than his two classmates. It had been difficult to get Chance to go along with the class, he hadn’t really perked up until Roman started introducing anal stimulation to the students mid week. 

“Go ahead! Keelay won’t bite, you're free to mate with her.” Roman walked up to the mouse boy and started gently pushing him towards the girl’s well used mound. He still looked nervous, and Roman tried to console him. 

“It’s all right, this is perfectly natural. We all go through this course, everyone does it. It’s just us, all you have to do is make an attempt and nothing more. Feel free to go at your own pace.”

That seemed to calm the boy a bit as he took a few more steps closer, the tip of his dick now resting right under the raccoon girl's tail. He fumbled with his cock a bit, tried aiming a bit lower and pushed in gently. He apparently found his mark as both the young teens gave a big moan. The mouse seemed to stumble forward a bit, causing his dick to slam deep inside the pussy in front of him, causing Keelay to give out a shriek of pleasure. 

“Oh! Sorry!” said the mouse as he pulled back just a bit. 

“No no, I think Keelay is quite enjoying that actually, right Keelay?” asked Roman. The raccoon girl just gave a thumbs up as she took a few deep breaths, feeling that larger cock filled her out. 

“Oh ok…” responded the mouse boy.  He started to gently rock his hips back and forth, breathing deeply the whole time, looking down and watching his cock slide in and out of the girl's passage. Unlike the other two boys though, instead of thrusting faster and faster, he went slower and slower, until finally he stopped with a bit of a dejected look on his face. 

“Im…not sure I can do this…” he said to his teacher, showing a partially limp dick in his paw.  

“That’s fine Chance, you can still pass the class by just attempting to mate, you’ve at least met that minimum.” responded.  It didn’t seem to change the mouse’s mood though.

“I mean… I want too, but I just….” he trailed off, looking off to the side. 

“What’s on your mind? I can try to offer some help.”

“Well…I mean this worked best when I was in her position, with the other boys…” he pointed at Keelay, more blush falling over his face. 

“Oh!” responded Roman, “well, I can actually help you out there if you like. I can just push inside you while you finish your assignment inside Keelay, if you think that would help.”

The mouse boy's ears perked up at Roman’s words, looking up at the older adult fox. The fox had his own cock in his paw, the show the two boys gave earlier keeping his rock hard the whole time. Chance looked down at the cock, and his own crotch responded with a twitch. 

“You…you can do that? Like, you’re allowed? We’re allowed?” asked Chance looking a little bewildered.

“Of course, I’m your teacher and I’m here to help you complete the course, even have sex with the students, as long as it’s purely for educational purposes.” responded Roman.

Keelay, still bent over the desk, snorted and gave a hearty laugh at Roman’s comments. Roman rolled his eyes and let out a “shush” to the girl bent over. Chance didn’t seem to notice the exchange, now focused on his teacher's cock. 

“Y-yeah lets try that…” he said nervously. By this point his dick was rock hard again in his paw. 

“Hey as long as you don’t tie with him, you promised!” said Keelay, looking back at the two males. 

“Uhh…promised what?” asked Chance, looking at Roman.

“Nothing, nevermind, don’t worry about it,” responded Roman, giving a look down at Keelay who only beamed back a big smile. 

Roman went to his bag and fished out a bottle of lube, trotting back over to the pair.

“Alright, take your position, where you were before. Then I’ll push in, alright?” said Roman, lining up behind the mouse boy.  Chance nodded and aimed his cock back where it was, once again feeling it slide right inside Keelay’s passage. The racoon girl gave another moan, though Chance remained silent, focused on doing what he was told. He flicked his long, thin tail as he felt Roman’s paw prodding under it, pressing up between his cheeks as his teacher lubed it his rear end. 

“Now, I’m a bit bigger than your classmates, so we’re going to need a bit of lube here…” 

Chance’s face went flush as he started to feel his teacher’s tip pressing right between his cheeks, and with a slow, gentle push he felt that cock break right into his rear.  That elicited a loud moan from the mouse, rivaling Keelay’s.  Roman kept pushing, inching further and further, until finally his bulbous knot was resting right against the mouse’s tight hole. 

“There we go, that's all the way in, how does that feel?” asked the older fox down to the younger mouse boy.

“That's…that's great…” responded the mouse through labored breaths and moans. Roman started to push back gently, then press forward again, watching as that caused the mouse’s hip to go flush with Keelay’s rear end, burying his whole length inside her. Roman kept giving soft, gentle thrusts, not trying to push too hard but enough to keep the teen pushing back and forth inside the raccoon girl’s pussy. Roman was enjoying himself more than he expected, his height allowed him a clear view over the mouse’s shoulder to watch the cock sliding back and forth inside his occasional young lover, all the while the tight mouse tail was gripping his cock tightly. He kept it up for some time, tugging back, pushing forward, the three working in rhythm led by the older teacher. It took a good bit of concentration and restraint for Roman himself not to just  explode inside this kid’s tail, for someone new to sex he was impressed how well this kid could take a dick. 

Fortunately Roman could hear Chance’s breathing getting quicker and quicker, those cute squeaks getting louder and louder, the tell-tale signs that the mouse was getting close. Just a few moments later Roman suddenly felt that mouse’s tail squeeze hard around his dick as he gave a loud squeaky moan, unloading yet another batch of seed deep inside Keelay. Once the boy started to relax, Roman pulled back, his dick falling out with a wet flop. Chance too leaned back after starting to catch his breath, and a rush of warm cum followed him, oozing out to the ground beneath them. 

The mouse kept panting, the boy seemed to be radiating pleasure as he worked to catch his breath. 

“That…was..perfect…” he said, looking at the mess of a raccoon read end then back at his teacher’s throbbing dick that was just inside him. 

“Good! I’m glad you enjoyed yourself, that’s what sex is all about anyways.” responded Roman, handing the mouse boy a towel to clean up. He watched as the boy started to gather his clothes, slowly dressing himself once again, though the wet spot on his pants was still clearly visible. He didn’t seem to mind, or notice though.

“Thank you for coming by to finish the course, you’ve definitely earned your A” said Roman.

“Thanks! I…really enjoyed that…” he responded, trotting out the door. 

That just left the two of them again, Roman and Keelay. The fox looked back over to the desk Keelay was bent over, but she had managed to turn herself around, now laying on her back with her legs splayed open wide. 

“Now it’s your turn,” she said with a devious smile, the other boy’s cum still dripping from her snatch. 

Roman could only smile as walked up to the young raccoon, cock still in his paw. 

“Of course, thank you for being my assistant today” he said, casually pressing his dick right up against her stretched hole and easily sliding right up inside.  Both of them gave a warm, familiar moan as the pair went right back to coupling, neither having any interest in any delay. 

“Did you enjoy Chance’s cock?” asked Roman, starting to gently hump back and forth inside the young teen. 

“Mmhmmm, he was big.  Bigger than the other two…they were kinda small to be honest.” 

“Hey, be nice,” responded Roman, “they’re your age, they’ll keep growing.  Not everyone’s the size of an adult yet.”

“Oh, it’s fine, I don’t mean it in a bad way, just saying…” responded Keelay. “So, how was the mouse’s butt? He feel pretty good?”

Roman started to hump a little harder, his knot banging right up against those pussy lips. He was so pent up, after being teased and edged for some time he could feel his release coming soon. All he needed was to plunge that knot inside and it would push him over. But he held back for now.

“Mfff…he actually did feel pretty good…it’s no wonder the other boys enjoyed fucking him so much the last few days, he has a wonderful tail on him.  I had a hard time not just cumming in him, to be honest.” Roman’s pace started to pick up, his moans getting a bit louder as he kept thrusting, but keeping that knot just outside each time. 

“Well I’m glad you didn’t, you gotta put all of that inside me..” Keelay’s conversation had started to go a little faint as she too was moaning louder, squirming under her teacher feeling that knot keep bumping right up against her opening.

“Yes..ma'am…” responded Roman, giving a few more hard thrusts until he couldn’t hold back anymore.  He pushed hard, and felt that big knot slip right inside her. The warm, tight pulsing around his knot made him moan, he gripped the young girl in front of him as he unloaded inside, his dick pulsing and throbbing and shooting warm fox seed deep up inside her.  Keelay squealed out happily, that knot pressing all the right buttons as she too was pushed over the edge, grunting and squirming under on the desk.  The two of them held that pose as they both breathed heavily, riding out their heavy climaxes with each other. Eventually Roman opened up his eyes and looked down, only to find Keelay staring right back up at him. He looked further down and could see the outline of the knot buried inside her crotch, that tight passage sealed shut with the thick throbbing knot tied inside it. 

“Knots…are amazing…” Keelay said, still lightly squirming as he can feel the warmth spreading out inside her, that cock still pumping seed while they’re tied. 

“I’d have to agree, they are quite nice…” Responded Roman, tracing a paw digit along the edge of that bulbous base. When they were first fucking he could almost make out his entire cock inside that small frame, but now that growing belly of hers hid any chance of that. Roman gently rubbed up and down that soft stomach, enough to make Keelay squirm and laugh gently at the tickling. 

“I wonder what species is growing in there…” he asked, giving himself a smile.

“Ohh, do you think it's a fox?” she responded through giggling.

“It definitely could be, we are both mammals and that's not uncommon. And two foxes mated with you during class, we doubled our chances after all. But you can’t count out a horse, or wolf either.  Maybe even a slim chance you could have a bird in there.” 

“ A bird?? Is that even possible?”

“It’s very very rare for mammals and avians to successfully mate ... .but it is technically possible…most likely though, it'll be a raccoon, just like you. ”

“Do you think they’ll be as horny as me?” she said with a laugh. 

“I think it’s definitely possible,” responded Roman with a chuckle as well, “I think horniness is definitely passed on through your genes. At least that’s what it seemed like in my house growing up.”

“Oh? Did you have any horny kids??” 

“Heh, well it was kinda hard to tell who exactly was the ‘father’ per se, but we were all pretty horny.  One of my earliest memories was helping birth my younger sister, and then once she was old enough the two of us mated quite a bit, and then I helped her give her first birth, a tiny little fox boy.” 

“And then did you mate with that kid?” Keela asked, a big devious smile across her face. 

“Well,” Roman chuckled, his eyes staring out in thought, ”I was already starting to move out by then time they were old enough for that, but I remember he was really interested in his mother a lot more than me, or any of my brothers”

“Oh, you had brothers?”

“I had many brothers and sisters in that house. Or rather, everyone around my age I just called brother or sister, biologically who really knew, eh? Anyone my mother’s age I would just call aunt or uncle, anyone a generation below was just a niece or nephew. Made things easier that way.” 

“Oh, so there were a lot of foxes in there, right?” 

“Yeah, there were a lot of us, we pretty much all piled together in groups to sleep. I had four other brothers I was close to, we would get up to all kinds of things, games and such.”

“Games? Like what kind of games?

“Oh you know, things boys do. Who can shoot the furthest, who can cum the most often, who could cum the first or the last, who could fit the biggest things in their tail, whatever we could think of.”

“I bet you always won that last one eh?” Keelay said with a sly smile.

Roman responded with another small laugh, “I was pretty happy to have things inside me, to be fair. Especially my brother’s cocks, I probably bottomed the most between us all.”

“But you still had sex with girls right? With your sisters?”

“Oh yes, of course, quite often. They were all pregnant pretty regularly too, I imagine my brothers and I were most likely responsible for that.”

“Mmm, it must be nice to be able to be pregnant so easily at home…” Keelay trailed off her voice a bit.

“Yes, I know, your parents were not too happy when you showed up pregnant. They aren’t from here and just didn’t know any better, once I explained sex ed to them they seemed to be a bit more understanding. Are they still giving you any problems?”

“Oh no, it’s mostly fine now, we just don’t talk about it…did you tell them you might be the father??”

Roman laughed, “No no, I don’t think that would have gone over very well, I told them it was likely another boy in class.  But that’s also why we really should not be talking about what we’re doing here on Fridays, either.”

“Oh I know, I won’t mention it.” 

As their conversation lingered, Roman could feel his knot softening. He gave it a small tug and felt it slip right out.  A warm gush of liquid fell to the floor once more, a small puddle of mating juices forming below.  Both of them signed content, Roman tugged his sheath back over his softening cock and Keelay reached down to feel her stretched, slick hole. 

“Let’s not send you home messy this time, eh?” he said with a smile as Roman leaned down eye level with her pussy.  His tongue reached out and he lapped right over the wet slit, licking up all the leftover cum.  He could taste a variety of different flavors of male species inside her, lapping all of it up happily. Once he felt satisfied he stood back up, looking at that cleaned crotch. 

“There you go, best not get your parents too riled up again.”

Keelay wiggled herself down off the desk, she trotted over to her hoodie and tugged it right on over herself. While she was technically bottomless, the oversized hoodie concealed her nethers. Another compromise she had to make with her parents. 

“Goodbye Mr. Roman,” Keelay trotted up to her teacher and gave a small peck right on the lips.

“Bye Keelay, get home safe.”
