Fury Sex Ed.


We all knew it was coming, we all knew it was going to happen at some point, and ladies and gentlemen, it is here. It's a movement that has taken to a bit of popularity on sites like e621, and it's one that, like it or not, is here to stay. It is the rise of the Night Light smut content.

Now, I for one am here to welcome Pouncer, Ruffrunner and Dart into the wonderful world that is smut, and I think the best way to welcome them is by having their parents teach them the ins and outs of sex, pun intended.

This is not an incest story, in case that was on anyone's mind. While I do have a slight thing for incest, I'm not sure if that would bode well with the readers on here. Or maybe it could, idk, maybe give me a review about it.

Also, for context of this story, the Night Lights will be around the age Toothless was when he met Hiccup so it will be a bit more appropriate.

That is all, hope you enjoy!


A lot has changed in the 25 years since the dragons of Berk left to live on their own, and one of the biggest changes is how much the Alpha's children have grown.

All 3 of them are now getting very close to entering their adulthood, so to commend that, Toothless and Luna felt like it would be a good idea to take them to an island near The Hidden World's entrance along with Stormfly and Cloudjumper.

Ruffrunner, the green eyed black headed son, was the first to speak up and ask, "Alright, Dad. Why did you bring us out here?"

Toothless replies, "I'm glad you asked, Ruff. Today, your mother and I will be teaching you three the basics of a very important lesson that will very likely carry you into adulthood. Mating."

This gets raised brows from all 3 Night Lights. Dart, the blue eyed daughter, asks, "Mating? Why would we need to know how to do that?"

Toothless replies, "Well, Dart, as you know our numbers aren't what they once were and I've only got so many years on me so, when my time does come, it will be up to you three to pass on the Fury species for future generations."

Luna nods. "That's right. Now, we will be going over all the basics of anatomy, safety, and if you three are good enough, we might let you do a little demonstration."

Pouncer, the white scaled son, then asks, "So, why is Stormfly and Cloudjumper here then?"

Toothless replies, "Well, Pounce, the answer is simple. You see, obviously your mother and I aren't going to let you do anything to us, that would be quite odd, so we brought our friends here to act as demonstration models."

Stormfly nods. "We're just here to help your parents show you exactly what you need to see."

Cloudjumper adds, "That's right, we are always here to help Toothless."

The Night Lights look to each other in excitement over this lesson, so they all sit down as Luna walks over to Stormfly. "Alright, we will first begin with female anatomy. I want all 3 of you to pay attention, especially you, Dart. Stormfly, if you will."

Stormfly nods and lies down on her back with her rear facing the Night Lights, spreading her legs for them to see. Luna then says, "Now, if any of you have any questions, feel free to ask. First, we have these squishy sacs called mammary glands." She points to the set of two nipples along Stormfly's udder. "These things don't really develop unless a dragon is pregnant, but the purpose of them is to store milk for when their hatchlings are born."

Pouncer then holds up his hand and asks, "But wait, I've seen you with more than one, Mom."

Luna nods. "Good point there, Pouncer, different dragons will have different varieties of mammary glands. For Stormfly and other Nadders, they have an udder that rests between their hind legs whereas dragons like myself have a set of six breasts that run from my chest down to my stomach. Some dragons, like Gronckles, only have four of them while Monstrous Nightmares only have two."

Ruffrunner then asks, "So, why do some dragons need so many of them?"

Luna replies, "Well, Ruffrunner, it all depends on how many hatchlings, on average, a dragon has per litter. Monstrous Nightmares only have about two or three while Gronckles tend to have three or four."

Stormfly adds, "My udder might only be one sac, but it has a set of multiple nipples on it to help feed my young, like my son Spike for example."

Luna nods. "Excellent point there, Stormfly. Alright, from there we move down to the central reproductive organ for a female, the vagina." She points to Stormfly's vertical slit. "These are where fertilized eggs are stored until they are ready to be laid."

"So, how does an egg get fertilized?" Ruffrunner asks.

Dart smacks him on the back of the head with her tail. "With a male's sperm, egghead. How exactly have you made it this far in life?"

Luna replies, "Dart, be nice to your brother. You are correct, however, but we will go over male anatomy in a little bit. Now, like with mammary glands, dragon vaginas come in all different sizes. Some are vertical, like Stormfly's, while some are actually horizontal as well, like my own."

Pouncer then asks, "So, what does it feel like to lay an egg?"

Luna replies, "Well, as someone who's popped 3 out of me, I can tell you this. It's like defecating but a lot more painful because eggs tend to be a lot bigger."

Pouncer thinks about it for a moment before his eyes widen. "Oh…I'm suddenly glad I'm not a female."

Toothless adds, "Be glad you're not a female Terrible Terror either. Their eggs are about the size of their bodies."

Luna gives Toothless a slight glare before moving on. "Anyway, inside the vagina we have the uterus where the egg stays stuck onto until ready to be laid. Further back, we have the fallopian tubes where unfertilized eggs travel through into the uterus and from the ovaries where the eggs are created. Any further questions?"

With a bit of silence, Toothless begins to walk over to Cloudjumper. "Perfect, we're ready to move onto the next stage of our lesson, male anatomy. Pounce, Ruff, I do expect you two to pay attention here, but Dart I do think you can learn something too."

He nods to Cloudjumper and he lies down in the same position as Stormfly, making sure they get a good view of his genital slit.

Ruffrunner gets confused about something and asks, "Wait, Cloudjumper has a slit like Stormfly's. Is Cloudjumper a girl too?"

Cloudjumper chuckles a little to that. "I know it's a little confusing, Ruff, but my genitals are actually stored inside of this slit. Watch." He rubs the slit a bit and out comes his balls and the tip of his cock.

Ruffrunner's eyes widen. "Whoa, that's weird. Kinda cool, I guess, since I guess you can hide your stuff from others."

Toothless then begins. "Ok, first off we have the testicles or balls." He points to Cloudjumper's scrotum that was bigger than Toothless's head. "These orbs are where sperm is created and stored until they get shot out through the penis, more on that later. Now, some dragon's testicles are internal meaning they are inside their bodies while others are external."

Dart then asks, "Why is that?"

Toothless replies, "Well, it all has to do with body temperature. Dragons with warmer body temperatures, like Monstrous Nightmares, tend to have external balls as their heat could end up killing sperm while those with internal balls, like your brothers and myself-"

Dart puts up her hand. "Ah, I didn't need to know about them."

Toothless sticks his tongue out to that. "Like it or not, Dart, it is important to know. Anyway, our balls are internal because our body temperatures are cool enough that our sperm can live happily inside. From there, we have the penis."

He gestures to Cloudjumper's half hard, 20 inch long cocks. "The penis is a long shaft that is used to deliver sperm from the testicles and into the vagina. The sperm will then fertilize the egg and, within a matter of months, a new baby dragon will be born.

Now, like the vagina and mammary glands, dragon penises come in all different shapes, sizes and forms. Some dragons, like us Furies, have penises similar to wolves in that we have a bulb on the end called a knot that ties you to your partner while you deposit your sperm, ensuring pregnancy."

Ruffrunner then asks, "But, when you 'tie the knot' is there a way to get out of it?"

Toothless nods. "Good question, Ruff. Yes, there is, you just need to wait a minute or two for the knot to soften, then you can pull yourself out.

Anyway, some dragons have bumps or barbs running along their penises for added pleasure to the female, and some dragons, like Cloudjumper here, have two or even more penises."

Pouncer asks, "Does that mean that Cloudjumper can get two females pregnant at the same time?"

Cloudjumper nods. "Yes, actually. However, this isn't the case for all males with multiple penises. Zipplebacks, for example, have two of them but one fires a fluid like substance while the other shoots sperm cells that mix together to form their semen."

Toothless nods. "Exactly right, CJ. Now, when a male gets aroused, their penis fills up with blood and becomes longer and more stiff in what's called an erection. An erection shows that the male is ready for sex. Now that we've discussed anatomy, are there any other questions?"

Pouncer asks, "Yeah, what do you do if you get an erection when you're not even about to have sex?"

Toothless chuckles to that. "Pouncer, that's just the issue with being male. Random erections will happen and they will be a tad embarrassing when they do happen. What I've found is a good way to help is to just try to think of the least erotic thing you can possibly think of."

Pouncer ponders this for a moment. "Yeah, that could work."

Toothless nods. "Alright, you three, you have been taught the basics, now I'd say it's time to go a bit more practical. Let's see, Dart, why don't you pair up with Cloudjumper, and the boys can take Stormfly?"

Dart's eyes widen and she blushes. "Wait, we're about to do it? Like…right now? Uh…I don't know how I feel about this."

Pouncer adds, "Yeah, besides, what if Ruff or I end up getting Stormfly pregnant?"

Luna nods. "Don't worry. Furies and Nadders are not biologically compatible so it won't be possible. Same goes for Furies and Stormcutters so you'll be fine too, Dart."

Pouncer nods. "O-ok but…well…"

Dart adds, "I think what Pouncer is trying to say is that maybe we'd be more comfortable trying this stuff out on mates that we find."

Luna motions her head to her left. "Your brother doesn't seem to mind."

Pouncer and Dart look down to see that Ruffrunner currently had his face stuffed between Stormfly's legs and was eating out her pussy. Dart almost yells, "Ruffrunner? What are you doing?"

Ruffrunner looks back and replies, "Hey, the offer just seemed to good." before going back to licking.

Luna comments, "Nice work, Ruffrunner. What you are doing there is known as foreplay, it's basically making your partner feel good before the actual sex begins. While you're at it, maybe give those nipples of hers a few squeezes, but not too hard. You don't want to hurt her."

Ruffrunner nods and raises his claw to squeeze Stormfly's erect nipples, enticing even more moans from the Nadder. Toothless walks over and asks Stormfly, "How you holding up, Stormy?"

Stormfly replies through moans, "His tongue is like velvet!"

Ruffrunner raises his head and says, "Well, if you like that, then you'll love this." He was about to put his 13 inch, erect dick in her pussy when Luna stops him.

"Now, Ruffrunner, here's where you need to be a bit more careful. While sex is enjoyable, it can also be painful, especially to the female, so before you go sticking that thing in there, you need to know a few rules.

Always make sure you ask before putting it in there, then you can get verbal consent from your partner, and sex without consent is considered to be rape, and we don't want that.

Listen to your partner. If they're telling you to slow down, then it's fine. It usually means that they just need a moment to adjust to having you in there.

Now, with that in mind, is there something you need to ask Stormfly?"

Ruffrunner nods and looks to Stormfly with his green eyes before asking, "Stormfly, is it ok if I penetrate you?"

Stormfly nods. "Oh, definitely." Ruffrunner smiles before moving his front legs up so they're straddling over Stormfly's shoulders as he proceeds to push the tip of his cock inside her pussy, making both of them groan with delight.

Dart looks away and says, "I'm not sure if I can watch this. Pounce, you with me…? Pounce?"

"Stormfly, you mind if I join?" Pouncer asks. Dart looks over and sees Pouncer standing next to Stormfly and Ruffrunner with his own 13.5 incher hard as a rock.

Stormfly groans. "Please. I need more."

Luna thinks for a moment, "Looks like her vagina is busy at the moment. Luckily, with females there's always more than one hole. Here, Stormfly, why don't you lift up a little bit?" Stormfly nods and has Ruffrunner lift his backside up while she puts hers up.

Pouncer smiles at this and proceeds to slip under her and push his cock into her anus while Ruffrunner continues his work with getting himself into her pussy. Neither of their knots were out yet, but this didn't matter as both Night Lights push their cocks into the Nadder's holes.

Dart continues to watch with a tinge of disgust but also with a bit of curiosity, one of which seemed to outweigh the other. She had to admit that it did look like fun, especially given Stormfly's groans and moans.

She looks over to Cloudjumper and notices that his cocks are now fully hard…and are massive. Each of them are longer than her tail. Somehow, though, curiosity got the best of Dart as she walks up to Cloudjumper and asks, "Cloudjumper, could you…fuck me?"

Toothless raises a brow to that. "Hey, you've already got the language down. Proud of ya, Dart."

Cloudjumper nods. "And yes, I would be happy to. However, as you can see I am quite bigger so we will need to make sure you're ready."

Dart nods and proceeds to sit on top of Cloudjumper's face, pressing her pussy against his mouth where he proceeds to lick in and out of her pussy, getting it lubed up with saliva.

While this was going on, Pouncer and Ruffrunner were continuing to push their cocks into Stormfly's anus and pussy, respectively, stretching her out and making her moan deeply.

Both boys were going at a sort of rhythm where as one pulls out, the other pushes in and so on, giving her maximum amount of pleasure.

Cloudjumper's long tongue was quite effective at getting Dart's pussy well lubed up so Cloudjumper looks up to Dart and asks, "Are you ready? If you want, we can just put one in for now."

Dart leans back a bit and even though her backside is over Cloudjumper's face, she could still feel one of those dual rods poking just above the base of her tail. Dart looks over to Stormfly once again and sees how much fun she is having, so Dart looks down and replies, "…Yes."

Cloudjumper nods. "Alright. I'll let you choose the pace. If it's too much, don't hesitate to stop."

Dart nods and proceeds to lift her rear up a bit before moving down and positioning the tip of one of those leaky cocks to her pussy lips. She takes a few deep breaths before pushing back a bit more, letting that hard dick slip into her pussy, stretching it out instantly.

Once the cock was in, Dart had to take a good moment to collect herself and wrap her head around the feeling of having such a large object inside her. Cloudjumper coaches her. "Deep breaths, now. Remember, you're in full control here."

Dart takes a few more deep breaths before proceeding to push herself down on the massive rod, making it spear her insides and open her up wide.

Dart found that, due to inexperience, there really wasn't much she could actually take, so she just stuck with whatever she could get in there and proceeded to move herself up and down. Dart peeks her eyes open and says, "I'm sorry. This is it."

Cloudjumper groans and replies, "Don't worry about it. You're lucky that the tip is the most sensitive part of my dicks. Just take it slow." Dart nods and continues to move up and down that big tip.

Pouncer and Ruffrunner, on the other hand, had no issue getting their cocks in all the way to the knot in Stormfly's holes and were continuing to go at that pace mentioned earlier.

Pouncer decides to slip his right front paw down to massage one of Stomrfly's nipples and Ruffrunner followed this by putting his own paw on the other nipple. Ruffrunner opens his eyes a bit and asks, "How…Is…it?"

Stormfly replies, "Heavenly. I've actually never had two in me at the same time."

Pouncer replies, "We're happy to help, then."

Toothless had walked back over to sit next to Luna and say, "You know, all this going on is getting me in the mood too."

Luna raises a brow to that. "Are you saying you're getting turned on by watching your kids mate?"

Toothless blinks to that. "Huh. Guess that does sound a little weird."

Luna smiles and pushes Toothless onto his back before straddling over him saying, "Well, you're in luck because I'm in the mood too."

Toothless smirks and says, "Well played, Lighty. However, you forgot one thing." He flips them so that now he's on top with his hard 14 inch cock rubbing against Luna's anus. "I'M the Alpha around here."

Luna smirks back. "Well then, Mr. Alpha, show me what you've got." Toothless didn't need to be told twice as he pushes his hard cock into her anus, stretching it out and making her moan deeply.

Now, things had escalated into an almost full on Fury orgy. Dart kept up her work with moving the tip of Cloudjumper's top cock, Pouncer and Ruffrunner continued to double penetrate Stormfly, making her mind melt with pleasure, and Toothless had gotten to his rhythm inside Luna's anus.

Pretty soon, Pouncer and Ruffrunner's knots had popped out of their sheaths, so they proceed to push them inside, the force of which causing Stormfly to yell out in orgasmic bliss as her pussy sprays juice all over Ruffrunner's cock.

The warm juices was enough to set Ruffrunner off as his cock bursts with cum that fills up Stormfly's pussy and, despite the knot, started to drip a mix of cum and vaginal fluids down onto Pouncer's cock, setting him off and making him shoot his own load into Stormfly's anus.

Dart, on the other hand, didn't take long as that massive Stormcutter cock presses her G-spot and causes her to squirt some fluids that coated the tip. The warmth of the fluids, however, was also enough to set Cloudjumper off as both of his dual cocks explode like a volcano with cum, the one outside Dart ended up firing upwards and down, effectively coating Dart in the white fluid, while the cock in her fills her up, making her inflate a bit, before shooting out of her pussy and coating his chest and stomach.

Toothless, despite having started later than the rest, was quick to push his own knot in as he unloads his balls into his wife, making her yell out in the same amount of bliss as Stormfly.

Once all 7 dragons had settled from their orgasms, the guys pull out of their respective ladies and they all take a moment to bathe in the glory.

After that moment, Toothless says to the Night Lights, "Well, guys, hope you all had fun and learned some valuable lessons."

Dart replies, "I've learned that I have a long way to go before I'm really ready for hard sex."

Pouncer replies, "I now know that the vagina isn't the only fun place to stick it into."

Ruffrunner replies, "I just can't wait to do that again. That was fun."

Toothless nods. "Well, perhaps now once you find someone that you truly care about, you'll know what to do."

Luna replies, "Of course, you'll only want to do it if you both are certain that you're ready for it. Well, for now, great job you three, I have to say that I'm pretty proud of you, and I hope you'll remember this for the rest of your lives."

Once all of them had gotten cleaned up, they head back into The Hidden World where Stormfly and Cloudjumper go back to their own homes and the Fury family heads back to theirs with excitement and bliss on everyone's minds.
