Biology Lesson

Summary:

After an argument with his dad about the birds and the bees, Dapper figured he would just show him how it all worked.

Luckily he had all his siblings there to help teach.

Notes:

Featuring too many uses of the word cock and pussy

(See the end of the work for more notes.)

Work Text:

The kids were up to something. Bad knew that as soon as he opened the door of his school to find every single one of them seated patiently at their desks, grins a little too wide directed at him as he pauses in the doorway.

There was something dangerous about those grins, sharp teeth flashing that had Bad feel like he was an unwitting prey falling for a trap. Yet Bad found it hard to take the danger seriously. These were his kids, his small dragon hatchlings and as their teacher he should expect a prank or two. Doesn’t mean he would make it easy for them.

“You little muffinheads,” Bad huffs, affection in his voice as a smile begins to grow. They were growing up so fast and so devious. “What are you all planning?” He cautiously checks around the doorway, his glowing eyes narrowing as he doesn’t immediately seeing any droppers or dispensers that would splash him.

No one answered him, the kids grins only growing wider, Dapper throwing Bad a particularly smug grin. One that signifies trouble for the demon if he didn’t reel in his mischevious son.

“Dapper, you better not be planning any trouble for your dad,” Bad warns, finally spying a cleverly hidden pressure plate half under some carpet. “Oooh I see how it is you… you ragamuffin. You’re trying to meme me!” Bad giggles as he steps into the room assured now that he could reel in his unruly kids. He puffs with pride, side stepping the pressure plate easily, completely ignorant of the fact he was about to step on a trip wire right next to it.

Dapper’s grin only grew, sharp teeth now exposed as Bad was suddenly doused with a pink and black potion. The demon yelps as he was soaked through, backstepping to try and avoid the leftover liquid and instead stepping onto the pressure plate, a second pink and black potion dousing him.

The potion quickly sinks through his clothes and fur, leaving no trace besides a thoroughly embarrassed demon dad and a few giggling dragon children. Bad felt a flush of heat run through him, a blush covering his dark cheeks visible even beneath his hood. They had gotten him, the heat grows, a spark of pride starting even as he bares his fangs to the kids. Each dragon only looked to Bad with intense interest, looking as if they were studying him now.

“Alright you little ragamuffins, what was that? What potion did you muffin me with.” Bad grumbles, opening up his inventory to see the potion effects and to grab some milk, only to be surprised as nothing was there. There was no indication he had been splashed with anything. He still looked for some milk, better to be on the safe side. Digging through his backpack Bad let out a slightly frustrated huff, not a single bucket or bottle of milk being able to be found before he looks once more to the giggling dragon children, each one watching him with rapt attention. They had doubly muffined him and he couldn’t help the swell of pride and another flash of hot embarrassment run through him.

So far though there was no negative effects, nothing he could see in his inventory or any potion effects around him to signify it. The kids looked a bit disappointed as well as nothing more seemed to happen and Bad couldn’t help flashing them a smug grin back. “Little muffinheads.” He says affection in his voice as he heads to the front of the class. Seems their potion was a bust and it made Bad relax, heading up to the front of the classroom. “You’re all still in trouble, you ragamuffins, but for now we’re really behind schedule. I’ll think of something later. Especially for you Dapper, you muffinhead.” Bad huffs to his son, ignoring Dapper’s pout.

The demon begins his lesson, turning to the blackboard to teach the kids various ways to steal from someone without them being any wiser, gaslight gatekeep girlboss for the win. He felt very peculiar though as the lesson went on, stuttering over his words and panting. His brain slowly fogging up as heat rose in him, making Bad sweat. He groans as the heat spikes through his core, stopping midsentence to lean a dark hot cheek against the blackboard.

Bad’s mind was whirling, he knew this feeling, knew it intimately but he shouldn’t be having his heat right now, he had it just a couple of weeks ago, spending it at a safe place without any prying eyes. Yet somehow, he was feeling it crash through him, an aching emptiness inside as his body seemed to try and set itself on fire inside out. Bad stumbles, attempting to pull his hoodie off, his heat addled brain needing to get it off, all his clothing preferably, ignoring the small part of his brain screaming that he should absolutely not be doing that. His tail began to jerk in several directions, unable to decide if it wanted to raise or whip back and forth. He didn’t even think about the potions he had been doused with earlier.

Panting, the demon was able to get one of his arms out of his hoodie, exposing his undershirt and dark fluffy fur, before a cough sounded behind him. Bad whips around, bumping into and almost falling over the desk beside him. Each of the dragon kids were out of their seat and standing close to him, surrounding Bad, looking almost hungry. At the lead was Dapper, his pout regrowing into a smug grin, now with a hungry and rather devious edge to it.

Bad stifles a moan at their looks, horror now warring with want in his belly as slick gushes from his slit, soaking his pants. He only barely stops himself from shoving a hand between his legs and beginning to finger himself. It was very important he does not do that, especially in front of the kids, some part of him tried to reason, addled thoughts of milk running through his mind as he squeezes his thighs together. That was a mistake as the ache within him grew and a moan did slip out, long and drawn out in the classroom.

Bad pants, eyes dimming as he struggles to get himself under control. Frantically he grabs at his hoodie to try and hide in it, “C-class d-duh -dismissed… I- ah… I uhm… I need to—” He never got to finish as each dragon kid pounced on him, helping to pin him down on the floor on his front. They didn’t have to try very hard, their hands on Bad making another moan burst forth and the demon can’t help but arch his back, pressing against a suddenly flustered Richarlyson and Pomme before falling limp in their grasp.

Working together the kids were able to fully pull off Bad’s hoodie, using it to tie his hands, Bad couldn’t help the soft whimper that escaped him as soon as they stopped touching him. Their small hands felt wonderful on his hot skin and he began to forget exactly why they shouldn’t touch him. He lets out another whimper, legs involuntarily spreading as he presses his hot cheek against the floor. The room spun as his core ached, begging to have something fill him.

Dapper shushes him as they all begin to drag Bad over to the reading corner, draping him over a beanbag his ass in the air and face pressed. The demon panting and sweating as he arches his back, tail raising as if to invite them in. All the dragon kids pause at this, their nostrils flaring as they got a whiff of a fertile demon deep in heat. Dapper shakes his head, directing his siblings to fully undress the demon, his undershirt easily being pulled off and each of the dragon kids excitedly exploring the demon who was powerless to fight against their roaming hands, not that it looked like he wanted too.

Dapper quickly pulls down Bad’s pants, curious on what he would find. With all his reading he had been expecting a very different reaction to the potion, yet Bad had no bulge or indication of a penis. He had planned this as a biology experiment and to kind of get back at his dad for disagreeing with him on the birds and the bees the other day, in front of everyone else. He hadn’t really been expecting his dad to have a vagina.

Dapper stares at the demon’s puffy lower lips, a clear looking fluid practically dripping from him as Bad wiggles his hips, tail still up and curled out of the way. The dragon could feel something stirring between his legs as he looks at the slick muff, his dad’s pants fully pulled off and flung to the side with Bad’s other clothes. His own cock began to poke from his sheath as Dapper stared transfixed before he began to lean forward, wanting to know what his dad’s pussy tasted like. His tongue slips out and into Bad, long and probing as Dapper holds on and experiments.

Bad was losing his mind, keening and arching his back, brain turned to mush as the heat swept everything away. He knew he should be doing something, or maybe not doing something very important but all he could think about was the aching emptiness inside of him.

A sudden probing to his pussy has the demon crying out, clenching down on what felt to be a long and thin tongue, exploring his depths. Even more slick gushed from him as he thrusts back, grinding on their face not even seeing Dapper’s surprised expression before determination sets on the little dragon’s face. “M-muh moooore,” Bad keens, rocking his hips as he feels little hands grip onto his thighs. That wonderfully long and slender tongue coiling in him, lapping at his walls and making him writhe. He tugs on his binds, his heat fogged brain not remembering that his hands were tied, literally, nor his sharp claws that he could use to get out. He settled instead on humping back against the tongue, toes curling in pleasure. They were not very experienced but the enthusiasm and curiosity they had made up for it. Little claws gently pricking Bad’s skin as they held onto his thighs, keeping him steady. The demon could only take it.

Other little hands roamed over his body, exploring him and everything he had to offer. They ran through his fur, pinching at his puffy nipples against the beanbag chair, fingers curling his sensitive tail, tugging and pulling at it. He lost it completely when someone dragged a claw over his sensitive horns, then grabbed them and pulled.

A loud cry erupts from the demon as he climaxes, clenching down on the tongue lapping at his depths, even more slick. He sobs and rocks back, tears beginning to run down his cheeks as the pleasure slowly sharpens into pain, his aching empty pussy seeking something thicker and more filling.
He was a beautiful sight, the young dragons thought, each of them now beginning to feel the stirring of want in their belly. The want to keep him like this, pin him down and each have their way with the heated demon as he begs and sobs beneath them.

Dapper slowly pulls his snout back from his father’s pussy, slick running down his chin. His hat was askew and the normally well put together drake looked feral, growling deeply to his siblings as if he could read their mind. He licks his lips, pupils blown wide as he watches his dad, his strong, courageous, smart, unbreakable father, reduced to a puddle of tears and pleas. His father’s legs open wide, pussy just begging to be taken with his spaded tail curled up and out of the way. He was perfect. Dapper promised himself he would do more lessons with his dad, how else would the knowledge stick. And what better way than continuing with the one right now, what better way to teach his father in depth the birds and the bees than to give him an example.

Dapper was fully hard now, his cock tenting his shorts which he quickly pulls off, exposing his thick ribbed length. He wasted no time in standing over his father’s begging form, his mind a whirl with new sensations. The young dragon had read a lot about the bird and the bees, he knew the mechanics of it and the general theory. Had seen other animals in the wild engage in the act. Now was a chance to test it out, Dapper muses, two fingers slipping into Bad’s pussy to feel him out. His movement was methodical, stretching Bad a bit as the demon continued to squirm under his fingers. Dapper was aware of his siblings attention, this had gone a little bit further then what they were anticipating but Dapper was too invested now, his cock throbbing, wanting to get invested as well.

Taking his slickened fingers out of Bad’s pussy Dapper grabs his cock, stifling a moan of his own, pleasure sparking up his spine. Dapper began to huff as he presses himself against Bad, feeling the demon’s heat even through his fur. A shiver going through him as he grabs his thick cock and slots it neatly against Bad’s pussy, the tip poking in him. The demon seems to become a bit more aware at that, his tail curling lightly around Dapper’s waist to draw him in closer, the action causing Dapper’s cock the press in, slipping just the tip into Bad’s hot pussy. “Yeesss, moooore~” Bad whines, rocking back.

Dapper grew excited feeling the wet heat around his tip and gives an enthusiastic thrust, filling his own dad with dragon cock. It was fucking heaven, tight and slick around him and so very hot. Dapper lost all control, thrusting like a madman, no rhyme or reason to it all, all thoughts of lessons, experiments or otherwise running out of his mind as he buried himself to the hilt in Bad again and again.

Bad happily taking the thrusts, rocking with each movement, praises falling from his lips as Dapper holds onto him as Bad was finally FINALLY filled as he wanted to be. Clenching and milking the thick girth within him made Bad feel like heaven, pleasure pooling in his belly and growing. He couldn’t remember why he didn’t want this to happen, to have someone thrusting into his empty cunt filling him during the worst of his heat.

The other eggs were surprised at the turn that had been taken, they hadn’t expected Dapper to go this far and a few, mainly Tallulah and Chayenne exchanged nervous glances, unsure of what to do. As Dapper got into a steady rhythm and the room filled with the sounds his hips smacking against Bads, interspersed with the demon’s praises and pleas for Dapper to go faster and harder. Bad didn’t seem to be upset with them, if anything the demon seemed to really be enjoying himself even as he continues to cry, tears rolling down his cheeks but a huge smile on his face. Dapper as well looked like he was enjoying himself, looking almost like a feral dragon as his hips moved, thrusting rapidly into the demon, filling his own dad with hard thick dragon cock. And the longer the others watched the two, the hotter the other dragon kids felt.

Ramon began to go back to exploring Bad’s body, hands roaming and tugging lightly at him, drawing a hazy glance from the demon. Bad purrs, not seeing Ramon technically but the rather obvious tent the boy had in his pants. He makes an aborted move to tug Ramon’s shorts off hands fumbling as he was still tied up. The little mustached dragon doesn’t seem to notice, too busy on gently grinding against Bad, huffing as he waits for Dapper to be done. Richarlyson even took it a step further, tugging off his pants to let his own thick girth free, rutting gently against the demon, doing anything to help pleasure himself. He was soon joined by everyone else, even Pomme and Tallulah with their smaller cocks, rubbing against the demon in heat. And Bad was in love with it, his heat addled brain not able to tell that it was all his kids around him, using him. All he knew was that there was a nice thick cock finally filling his empty pussy and more cocks to use him when the first one was done.

Just the thought of that thick girth stilling and filling his womb up, giving him implings in the middle of his heat had the demon climax once more. Clenching and milking the thrusting length, much to the dragon’s surprise. With that climax though, came just a moment of clarity.

Bad opened his white eyes, gasping as he feels Dapper give a particularly hard thrust, rocking him. He lets out a small whimper, seeing all the other kids around him, cocks in hand, grinding and rutting against him as he feels his own son use his pussy. Worst of all was that Bad didn’t feel horror when he first came to, instead what he felt was intense pleasure, the darker part of him pleased that his kids were using him so. Bad attempts to push that part down, shaking instead to try and rise, but the hatchlings were thoroughly keeping him pinned, not that he was really trying. He found it very hard to concentrate on getting away when he could feel his son rutting against him, just knowing Dapper was set on filling him up and making him a mama all over again.

“D-dapp-Daah… Daaapper pleeeease~,” Bad moans, turning his head just enough to catch a glimpse of his son behind him. Dapper had his eyes closed, a look of determination on his face that in any other situation Bad would have found adorable. For now it made another curl of heat crawl up his spine as he feels that determination to pound his pussy. “W-wuwhu w-wait Wait, w-we can ta-t ah! Talk about this!” Bad wheezes, fighting against his body’s insistence to just give in, it didn’t help that Dapper began to speed up, feeling almost as if he was getting deeper, pounding on the entrance to Bad’s womb with each brutal thrust. The young dragon doesn’t seem to be listening, huffing as he hugs onto Bad, focusing entirely on his own pleasure.

“Dapp-Daah Daapper pleaaase, H-huh-heeat, I’m—mm~ heat, in heat” Bad tries again, squirming to catch his son’s attention enough that their eyes meet. Dapper looks surprised, slowing his thrusts to just grind in, making Bad’s toes curl and momentarily losing himself again. The small dragon still stops, hands gripping onto his hips with surprising strength to keep Bad still.

Bad was just thankful for the reprieve, even as his pussy desperately milks Dapper, trying to entice the dragon into thrusting once more. He would half to be quick before the heat pulls him under and he has his own son knock him up. Just the thought makes the demon shiver, grinding back on Dapper who gives a grind back but holds him still. “Y-yes, Yes. Thank you, I’m in heat… s-so that means… implings… I’d have your implings if you do this…” He finally pants out, hating himself for the thrum of heat the very thought of having his son’s implings.

Dapper blinks, tilting his head, a sharpened focus in his eyes as he stares down at Bad’s flushed form. “Our implings? Our hatchlings?” He asks, his voice slightly raspy. That caused a reaction, the other dragons also slowing their pleasuring, each one watching the panting demon with renewed interest.

Bad didn’t notice the new attention he was getting, focusing instead on not rocking his hips or using his tail to pull Dapper in closer, his mouth running as he tries to beat down his heat. “Y-es yes yes, your implings, your hatchlings. If you keep going you’re going to make me a mama. S-so just get off of me and I can… I can ah…” He trails off, finally feeling the weight of all the kid’s attention on him, Dapper’s claws digging in enough to cause pricks of pain and most of all, that ribbed thick length in Bad twitching and throbbing even more, making the demon give his son over his shoulder a wide eyed plea. He sucks in a breath, feeling like he just made the situation worst. “Dap—” Is all Bad got out before Dapper hugged onto him and began to use his pussy with renewed vigor.

“Ours~” He growls out, a thread of possessiveness in his voice, his hips stuttering as he feels a growing pressure, some instinct guiding him to thrust in as deep as possible, hugging Bad close as he feels the demon’s tight pussy milk him even more. One hand letting go of his hips to grab onto the demon’s tail and pull using it as leverage.

“P-puhleeeaase,” Bad sobs out, as he feels his son’s thrusting grow harsher, the dragon finally reaching his limit. Bad didn’t know if he was begging for or against Dapper, yet he found it didn’t matter as the little dragon slams in deep with a roar, claws digging into Bad’s hips to hold him close, his cock throbbing within and releasing his seed deep into Bad’s pussy filling his womb. Bad gives another cry, feeling that flush of heat and wetness, knowing it’s too late, tears pouring down his face even as another orgasm rips through him, milking his son’s splurting cock in his pussy.

Dapper grinded against Bad, making sure that every drop was planted in as deep as it could go, his tip plugging up Bad’s womb so not a drop could escape.

Then slowly, almost gently, Dapper pulls back, dragging his length out of Bad’s depths with a lewd sucking noise. To the demon’s embarrassment he could feel his pussy attempt to clench and draw Dapper back in, a soft whine escaping him as he feels how empty he was now. Bad hangs his head, another sob coming as he realizes just what he’s done. He didn’t know what he was going to do, hanging over the beanbag chair in the middle of the dragon’s school, his cunt well used and dripping with dragon seed.

The demon didn’t have long to wallow as he suddenly feels another cock beginning to probe his entrance and his heat returns with a vengeance, hips bucking backwards to engulf the head of another thick ribbed girth. A soft rumbling moan starts behind him and Bad jerks to glance back, blushing hotly as he sees Ramon grip onto his waist and begin to thrust forward, sinking into Bad’s well used depths, some of his brother’s seed spilling out around him. Bad could still feel a lot of Dapper’s cum sloshing around in his womb as he’s once more rocked with each thrust.

“W-wai—” Bad tries to cry out, squirming under Ramon only for the dragon kid to redouble his efforts of fucking Bad into the beanbag chair, making the demon squeal as he was pounded, eyes rolling from the pleasure as another orgasm crashes through him with a wail, slick gushing around the new thick length. Bad falls limp, his heat growing to new heights, burning away all his rational thought as his dragon kids crowd around him eager for their own turn, Dapper coming up to the hazy demon’s head.

“Our hatchlings,” Dapper purrs, pressing a kiss right on Bad’s forehead before it all devolved into a haze of cum and pleasure for the demon. Each dragon taking a turn with him, filling his poor womb up to the brim with their seed. He wasn’t even spared from Pomme or Tallulah, the girls having smaller but still functioning cocks they put to good use.

By the time Bad gained back some semblance of sanity, his womb was full of cum, abdomen bulging slightly and his heat had burned down to a simmering ember. He suppresses a whimper, thinking already of his belly swelling with a new generation of dragons. He couldn’t wait to see it.

The current dragon generation though seemed to have finally tired themselves out and Bad knew he was burning this whole school down once he remembered how to walk again. For now though he was tired, sweaty and covered in a mix of cum and slick. Each of the little dragons were curled up on him, just as messy as he was, practically pinning him down and purring loudly as they slept. He was thankful they had turned him over letting him lay back as they covered his front even if he could also feel just how much they used him.

Despite what the future held and how much deep shit Bad knew he was in, he couldn’t help but relax, his more demonic side recognizing his new mates sleeping on him and knowing he was protected. With that Bad felt his eyes begin to droop, promising himself he would clean this up just after a little nap.

He was totally muffined though.

Right before Bad could drift off completely he heard an obnoxious squelching noise and opened his eyes to see Gegg standing over them.

“What the fuck,” Gegg says in Slimecicle’s voice.

He was doubly muffined.

Notes:

Uuuuh in my defense I wrote this on my period and extremely horny. Almost made like 3 different editions of it before I realized it's just fucking porn and then went here to post it. Thanks to bbhcunny for writing the story that gave me this idea, love your stories.

That said I'm actually thinking of a sequel, like bruh, this porn story gave me so many ideas what is wrong with me. The sequel would be called Study Notes, and probably be multichapter free use Bad with each of the kids. Yea I don't know either haha.

Hope you guys enjoyed, I know I did.
