Naruto’s Birthday Threesome (Naruto x Tsunade & Shizune)

Synopsis: It's Naruto's eighteenth birthday, and Tsunade and Shizune have a big surprise for the young ninja. To "prepare" him for his future life with Hinata, they will take him for a ride that will result in several pregnancies. This is not an NTR story, trust me.

"Happy Birthday…" Naruto said to himself while he was lying in bed late at night. The clock had just rung midnight, but he hadn't been able to find any sleep yet. Feeling melancholic, he let out a sigh. He would have loved to have spent his eighteenth birthday with Hinata, but sadly, his girlfriend had to cancel at the last minute. Feeling disappointed that Hinata didn't have any time for him, he had decided to just stay at home all day and spend the night at Tsunade's place.

'I guess I might as well try to sleep now.' He thought to himself and closed his eyes.

All of a sudden, the sliding door to his bedroom opened up and revealedTsunade and Shizune standing in the doorway, both dressed in their usual night robes. Naruto, startled by the midnight visit, jumped up from his bed, with his lower half still covered by his bedsheets.

"Granny Tsunade, big sis Shizune, is that you?" Naruto said while his eyes tried to adjust to the darkness. "What's going on? It's so late at night!"

Both of them simply grinned while looking back at the young ninja. Tsunade was the first one to speak up. "We're here to celebrate your eighteenth birthday, silly!" They both slowly entered Naruto's room, and the young blonde Ninja could see how their bodies sensually swayed with every step in his barely illuminated bedroom, even with their robes on. He would have lied if he had claimed to have never glanced at their sexy bodies when he thought that he could have gotten away with it, secretly admiring their soft and matured curves.

"You're finally a full adult now, Naruto. We know you're dating Hinata and that you plan to propose to her soon, and we're sure you will be a wonderful husband to her and make her happy."

"W-what does that have to do with anything?!" Naruto stuttered, being noticeably flustered by Tsunade's openness. It was true that Naruto had thought about proposing to Hinata and taking her as his wife eventually, but that was something he had planned for the far future.

"It has to do with absolutely everything, pipsqueak!" Shizune continued, "Being married means making your partner happy, outside and inside the bedroom. And that's why we're here tonight. We're here to make sure that you'll learn the skills necessary to be a good lover…for Hinata, of course!"

Naruto couldn't believe what he had just heard. This had to be a prank. Granny Tsunade loved to play those…but for some reason, he could sense the honest intent in their voices and demeanor. Before he could dwell on it any further, Tsunade went on to speak again.

"I hope you're fine with an old 'granny' like me, Naruto," Tsunade said while smirking at Naruto, "I'm already over 50 years old, and you never fail to point out how old I am, you little brat! But I guess you're not going to be a brat anymore after tonight."

"T-Tsunade-sama!" Naruto interrupted her. "I'm sorry, I really am! Don't worry about your age, if anything, it only makes you sexier to me!" The young man couldn't believe what he had just blurted out. Maybe he had somehow already given into the absurdity of the situation, but he had felt the need to praise Tsunade for her beauty. His own rampaging libido was doing the rest. He did just turn eighteen years old, after all. Yes, this was the perfect excuse to play along. Even if all this would turn out to be a massive prank in the end, it was still worth a try on the off-chance that it wasn't. If he was perfectly honest towards himself, this was the dream of any red blooded male, to spend the night with not only one, but two sexy older women.

Naruto looked at the both of them, how their large, full breasts pressed against the fabric of their silky robes from the inside. He gulped at the prospects of grinding his face (and other body parts) into their cleavage and it made his manhood throb in anticipation. Now that they had stepped even closer, he was able to make out their features better and take in their womanly scent. It seemed that both had put on some sort of perfume, and it only enticed him even further.

Shizune noticed the bulge forming underneath the sheets and couldn't help but respond. "Haha, looks like you like our surprise, Naruto. You've always been like a little brother to me and I just want the best for you. And I promise you right here and now, that I will always support you once you become the next Hokage, just like I've been doing for Tsunade here…and that support includes teaching bedroom manners to young studs like you!"

"Enough talk," Tsunade said with her arms crossed, causing her buxom bust to be even more prominent, "I think it's time to start the birthday celebration and the special training."

Tsunade was the first one to open up her robe, and Naruto's eyes almost popped out of their sockets. Sensually teasing him, she slooowly revealed inch after inch of her heavenly body to Naruto until her robe had hit the floor, revealing her outrageous outfit underneath. Tsunade wore a purple one piece bathing suit that would have been more fitting for an erotic hentai drawing than actual clothing. Revealing more skin than it hid, it also appeared to be several sizes too small, with her hips and tits being dangerously close to just spilling out of the strained fabric.

"Sorry, it has been some time since I last wore this and it's a little tight in some spots…but you seem like you don't really seem to mind, hehe~!"

And that he didn't. Naruto was practically glued to Tsunade's sexy frame, with his manhood jerking underneath the sheets while his eyes explored every inch of her sexy frame. For being already over 50 years old, her body was simply outrageous, with sheer endlessly soft curves that would put any 20 year old model to shame. She sported an enormous bust of barely contained round and firm tits, tightly squeezed together by their purple prison held together by thin strings, with her cherry tomato like nipples poking through the fabric.

Further down, Naruto noticed Tsunade's midsection. Some women might have been ashamed to have some more pounds on their hips, but it only made her that much sexier and alluring in his eyes, and Tsunade had no shame in presenting her well proportioned pounds with confidence. Her sexy and soft belly pudge only helped to accentuate her wide, childbearing hips, a sign of her potentially boundless fertility.

And finally, Naruto focused his gaze on Tsunade's crotch, where he saw a thick and hairy blonde bush poking out of the sides from the cameltoe of her purple bathing suit...and Naruto could once again feel himself gulp from the excitement.

"Ah, I see that you finally noticed!" Tsunade cood with a smirk on her face. Both she and Shizune had purposely grown out their lower pubes, knowing that it would only help to entice Naruto even further. Placing one hand on her hip and the other on her crotch, Tsunade began to playfully tug her own hairs, with the clear goal of making Naruto even more addicted to her bombshell body. The small tugs and pulls sent shivers up and down her spine, and she was only barely able to contain herself from her self-stimulation. She, just like Shizune, wanted to ravage this young ninja as soon as possible.

Now that Tsunade had finished showing off, it was Shizune's turn. Even though she was younger than Tsunade and not quite as well endowed, she still emanated the somewhat taboo and strangely alluring sex-appeal of a big sister. After dropping her own robe, she revealed a black kunoichi net-outfit that covered her entire body from her neck down to her feet, causing her soft skin to gently squeeze and rub against the many tiny holes of the net. She might have not been quite as blessed and ripe as Tsunade, but she would still have been considered an absolute beauty by any male who laid eyes on her…and Naruto certainly approved of her as well.

Just like the blonde Hokage next to her, he had always secretly lusted after her, but knew that it would have been highly improbable to act on his feelings. Just like Tsunade had done, Shizune had grown out her pubes and Naruto stared at a thicc, black bush between her thighs, proof that both her and Tsunade were indeed natural.

The only other pieces of clothing that the two of them wore were a pair of talisman shaped stickers over their nipples, hiding them and their areolas underneath. However, they did a poor job of actually hiding their shape, as their quadruple cherry nubs were positively poking and denting the sticky material outwards.

Shizune couldn't help but grin as Naruto was eating away at her appearance with his stares, feeling more than happy that her body was able to steal more than its fair share of stares away from Tsunade's.

"Naruto, don't worry about anything. You shouldn't think of all this as cheating. Just regard it as…preparation for Hinata. Yes, that's it. You're basically doing this just for her…and so are we, of course~!"

Naruto failed to quite follow Shizune's logic, but at this point he didn't really care. He loved Hinata dearly, and if he had been perfectly honest, it did nag at him that he would give himself to these older bombshells before her. But no more, Shizune's words acted like a catalyst for the young, blonde Ninja, almost as if he had found a way to avoid taking responsibility for what he was about to do.

And his body reacted promptly.

Moments before, his own manhood had only been half erect, only creating a small, albeit visible tent underneath the bed sheets. But now, this was no more. Stimulated by their outfits and sexy scent, Naruto sported a full fledged boner, standing at least thirteen or fourteen inches long, almost tearing through the bed sheets. Pulling the annoying fabric away, Naruto gave both hungry cougars a first look and whiff of his own massive manhood, and the effects were noticeable almost immediately.

Both Tsunade and Shizune were instantly intoxicated by the size of Naruto, how his cock was throbbing and already leaking a bit of precum. As an immediate reaction, both of their faces sported silly grins, with heart pupils forming in their eyes. They both rubbed their thighs together and began touching their pussies through their clothes in a foolish attempt to calm this primal urge that had begun to build inside of them.

They felt their chakra move towards their productive organs on its own, making them both aware of their femininity and heightened fertility. In this moment, they had become nothing more than two females in heat, ready to be bred by a strong alpha male that was showing off his breeding rod to them. Not able to wait any longer, they both crawled onto the bed and towards Naruto. Their clothes were strained to the absolute limit, with their massive titties dangling like two pairs of cow udders on their way to get milked.

"Mmmmh, I can't wait any longer, Naruto!" Tsunade said, with the saliva in her mouth threatening to overflow.

"Ohhh, me neither, I'm simply dying to get a taste of your manliness!" Shizune chimed in. "Let's prepare your pecker for our birthing holes, ok~?"

Now that the two of them had gotten even closer, Naruto first noticed that sexy dark black lipstick that both of them had put on, giving their lips a sensual black shine.

Tsunade began to lock onto Naruto's member, her eyes focused on its round, large tip. Her mouth was already salivating as the hearts in her eyes began to glow in an even brighter pink. Slowly, almost shyly did she place a little kiss on top, causing Naruto to jolt from the sudden surprise. However, it didn't take long for Tsunade to completely engulf Naruto's shaft and to smother it with her lips and tongue, drenching it in her hot saliva while taking in the taste and smell of his member.

Meanwhile, Shizune moved her head right next to Tsunade's and focused almost solely on Naruto's swollen testicles, with her soft lips and tongue gently circling around their mass. She gently sucked on Naruto's sack, even going as far as to try to put them into her mouth whole. It was as if she could actually feel the restless sperm inside with her sensitive lips, and her stimulation was enough to increase sperm production even further.

Naruto, feeling overwhelmed by this one in a million situation, could do nothing but grab onto the double cougars' heads as his body jerked, trying to hang onto dear life as he was on the receiving end of an incredible and sloppy double blow job, covering his genitals in slick saliva and black lipstick marks. Being backed up already, it didn't take him until he felt his balls clench and for his first load to shoot out of his engorged cockhead.

Almost by instinct, Tsunade pulled back and Shizune immediately followed suit, both of them squeezing their cheeks together to catch most of Naruto's load with their faces. Load after load landed onto them, and they could feel the heat and virility on their smooth skin.

"Oh wow, you really know how to glaze your sluts, big boy~!" Tsunade huffed while scraping the cum off her face and deliciously licking it up with her finger. Naruto tasted heavenly.

At the same time, Shizune circled her tongue around her lips to lap up any drop of seed that had landed on her face. Just in that moment, both of them felt their wombs and ovaries throb, almost as if they sensed the virile tadpoles that had just entered their bodies.

"We're so proud of you, Naruto! With a cock like this, you will have no problem with pleasing Hinata for years to come. And even better, you will have no problem making a new generation of ninjas. Damn, if any of this sperm would have been shot inside of our pussies, we'd be pregnant in no time!"

"I…I think it's still a bit too early to think about that!" Naruto responded. Even though the thought of Hinata carrying his baby did excite him a lot.

"Nonsense!" Shizune quipped. "As the man of the house, it is your responsibility to secure a strong bloodline! But let's leave that for later. In fact, I think it's time to show you something. Tsunade and I have another surprise for you."

And with that, both Tsunade and Shizune tugged on their outfits and finally freed their massive mammaries from their tight prisons, releasing their round balloon tits in all their glory…well, almost. They still had those pesky talisman stickers on top, covering their nipples and areolas. In the meantime, their nipples had grown even larger from orally pleasuring Naruto and actually threatened to rip through the fabric.

Before that could happen, both of them cheekily grabbed the edges of their talisman tape and slowly tugged at them. Each tug sent shivers up and down their spines from the stimulation of their hyper sensitive nipples and stretching their soft skin. With one last rip, they were finally freed from their sticky prisons, causing their delicious boobmeat to jiggle back in place from the sudden movement.

"You will now see why we put those on, Naruto."

The moment the two women had pulled off the sticky talismans, their chakra began to flow freely. Their already large breasts began to grow another cup size, and their dark pink areolas began to leak small, white droplets of milk.

"We can't wait any longer, our pussies are on fire! Come on Naruto, time to make a man out of you!"

And with that, both Tsunade and Shizune pushed Naruto down on his back before he could say or do anything in response.

"Just leave everything to us, enjoy yourself!"

Even though Naruto had just orgasmed, his pecker was still just as hard as before, a testament to his youth. Tsunade positioned herself and sat on top of Naruto's crotch. She pulled the purple fabric of her swimsuit aside to finally fully reveal her mature and hairy cunt, her blonde bush already soaking wet from her juices. With two fingers, she spread apart her pussylips, revealing their pink insides and her engorged clitoris.

"Come on, Naruto, fuck this old cougar cunt! Don't even think about using condoms or any other means or protection! We're going to teach you how sex between two lovers should be!"

And with that, Tsunade plunged down and impaled herself on Naruto's shaft, causing both of them to squeal in pleasure.

"Ahhh, you're a man now, Naruto! Congratulations, pipsqueak!" Tsunade cooed while she felt her insides being invaded and stretched.

"Please don't forget about me!" Shizune interrupted. The raven haired beauty mounted Naruto from the other size, facing Tsunade, and placed her soaked pussy right above Naruto's face, with her wollen pink petals squeezing between the holes of her net bodystockings. "It's good manners for the husband to eat out his wife to make her feel good, so go ahead and practice with me as much as you like!"

Naruto couldn't believe what was happening to him anymore. Here he was, with Tsunade riding his cock with her bare pussy while he was smothered by Shizune's lovely ass cheeks and wet love muff. It was a good thing that he had just blown his load over their faces, otherwise it would have been impossible for Naruto to hold back his orgasm for that long.

He could feel Shizune's pubes tickle his nose, but that didn't stop him from diligently fulfilling the task he had been given. Taking in her sweet and sexy scent, Naruto began to eat out her gushing pussy while Shizune grinded her hips against him, almost like she was fucking his face. His tongue invaded her dripping honeypot, trying its best to lap up every last drop of her sweet juices while his nose got overloaded by her fertile and musky smell.

In an attempt to split his attention between the blonde and black haired babes on top of him, the blonde ninja reached around Tsunade's body with his hands. He might not have been able to see anything thanks to Shizune's prized rear blocking his view, but he could still feel everything. He quickly dug his fingers into Tsunade's bountiful buttflesh and grabbed onto them hard.

Tsunade squealed almost immediately from the unexpected attention to her massively milfy ass and as a response could feel herself becoming even tighter around Naruto's invading shaft, with her silky smooth vaginal walls caressing his young dick. His length was so impressive that he actually poked against her cervix whenever she would plunge herself down, the final defense of her overripe womb. Every time he would bottom out, Tsunade would see stars while her cervix made out with Naruto's young and virile cock like a pair of depraved lovers.

"Ohhh, fuck, Naruto! You're so good at this! You're actually manhandling this 50 year old slut of a woman like she's a young and inexperienced whore. And not only that, you're also eating out Shizune like a pro!" Looking over to her friend, Tsunade could see that she wasn't the only one who was being overwhelmed here. Shizune's expression was as close to an ahegao as possible, with her heart pupils almost popping out of her eyes and her tongue swirling around uncontrollably.

Just in that moment, Tsunade realized that Naruto must have a natural talent for sex. If he was able to please Tsunade and Shizune at the same time like he was doing just now, he would have no problems pleasing Hinata, or any other woman for that matter. It was then and there that she decided to go all the way with him.

"Naruto, I think it's time for the final lesson." She cooed while grabbing his hands and guiding them towards her front. "You see, a husband must be able to give his needy wife many babies!"

Before Naruto could react, Tsunade guided him towards her lower belly and placed his hands onto her soft pudge.

"Naruto, please! Use your chakra and let it flow into me! Those 50 year old ovaries of mine need a small push to make them ovulate again! Admit it, you'd love nothing more than to shoot your nasty jizz into my unprotected womb and make me pregnant!" Tsunade was shivering all over with excitement now and Naruto could feel her pink pussyflesh twitch around his members, with her cervix greedily sucking his tip. "I'm offering you that chance now! You have no idea how many guys would love to be in your place right now!" She continued. "My pussy is completely bare and unprotected, any egg inside my womb would be completely defenseless against your swimmers! Heck, who's to say that it would just be one egg waiting in there? With a cock as virile as yours, you would have no problems giving me twins or even triplets!"

Naruto was already too far gone to be reasonable at this moment. Everything Tsunade had just said just sounded amazing, as if she was speaking directly to the most primitive parts of his brain. In his eyes, Tsunade was the sexiest old bitch on the planet. He wanted to, no, needed to shoot her full of his babies. Focusing what little control he had left, he did just as he was told and focused his chakra onto the soft folds of Tsunade's lower belly.

His fingers sank deep into Tsunade's soft belly, and thanks to his powers, it was almost as if he could feel her womb and ovaries directly. His energy flowed into them, causing Tsunade to squeal hard and her reproductive organs to throb even harder. It also had the pleasant side effect of making Tsunade's body grow even larger and thicker, caused by both of their chakras working in tandem to secure the most pleasurable experience possible for both of them. With her bust and hips now almost bursting out of her bathing suit, Tsunade's appearance came close to that of a broodmother or a pagan fertility idol.

It didn't take long for Naruto's efforts to bear fruit, and a sudden jolt of electricity rocked Tsunade's body, originating from her lower belly.

"Ohh, Naruto! You did it! I just felt myself ovulate! My need to breed is stronger than ever! Thank you for helping this old granny conceive! But I don't think you should call me granny anymore from now on, how about you call me 'Tsunade baa-san' instead~?"

"Of course, Tsunade baa-san!" Naruto let out in between his cuntplay on Shizune.

The outrageous threesome continued for a while, with Naruto firmly grabbing onto Tsunade's overgrown hips while she rode his cock, all the while Shizune ground her gushing cunt against Naruto's face. His face and crotch were now completely drenched in their combined love juices, and the smell of sex had permeated the bedroom and all of their senses.

Naruto couldn't hold himself back anymore. The double stimulation and the image of knocking up Tsunade simply proved too much after some time, and he felt the need to orgasm approach him again. His entire body stiffened and his hands cramped as they grabbed onto Tsunade's soft flesh, with rope after rope of his hot load splashing inside Tsunade and drenching her greedy and slutty cervix.

"Ohhh yes! I can feel it! Thanks to my chakra, I can actually feel your seed inside of me! Give me your entire load! I'll be your eternal breeding sow! Make me pregnant with tripleeeeeeeeeeets~! Tsunade screamed out those final words as her own orgasm hit her. Losing control over her bodily functions, she arched her back, threw her head back and grabbed her own breasts, literally milking them and squirting her white and pearly milk out of her swollen nipples all over the place.

Shizune orgasmed almost at the same time from Naruto's relentless tongue play. Her entire body locked up and she pressed her entire weight down onto the young ninja as her orgasm washed over her. A literal gusher of squirt juices shot out of her pussy and directly into Naruto's mouth who welcomed every last drop. Similar to Tsunade, Shizune screamed out her orgasm to the heavens, with her swollen breasts dripping copious amounts of mother's milk as her fingers dug into them.

After their initial orgasms had passed, both Tsunade and Shizune hunched over forward and fell into each other's arms, with their breasts and nipples sensually squeezing together and forming a quadruple mammary mass. Both of them tried to catch their breath, visibly exhausted from their mutual orgasms. Almost by instinct, both of them looked each other deep in the eyes and their faces came closer, inch by inch.

Stripping the last sense of shame away, they both cupped each other's faces and began to make out, their black lipstick clad lips kissing in a lewd lesbian display of debauchery. Thanks to Shizune's body being in the way, Naruto couldn't see what was going on, but he could definitely hear the slobbering moans as both cougars shared their saliva on top of him. Had he even caught a glimpse of all this, he probably would have cum again on the spot.

After their threesome had ended, the three of them had cuddled up in Naruto's bed, enjoying the afterglow of their incredible threesome.

"Oh wow, Naruto, I can still feel your little tadpoles wriggle inside of me in search of my eggs." Tsunade exclaimed while rubbing her swollen belly. "I would have never even dreamed about getting to experience motherhood at such an old age. Thank you!"

The freshly inseminated blonde bimbo placed a loving kiss on Naruto's cheek, with Shizune soon following suit on the other side.

"Naruto, I'm so proud of, my little brother!" Shizune added, "You really are a fantastic lover..but I can't help but feel a bit jealous!"

Shizune gently moved her hand to Naruto's bulge again. "If Tsunade gets to carry your babies, I want the same! I want at least twins, no, triplets from you!"

"Nothing easier than that, Shizune nee-san!"

--- Months later ---

"Naruto-kun, no fair! You said you wanted to wait for me!"

"Sorry, Hinata, but Tsunade baa-san and Shizune nee-san were just too clingy!"

It was a picture right out of a hentai doujin. Naruto was waist deep in the warm onsen water, with his back resting against the edge. Both Tsunade and Shizune were heavily pregnant and by his side, their big bellies and massive breasts gently floating in the warm water while their nipples leaked an almost constant stream of milk into the outdoor onsen and causing the water to become a tad cloudy.

Hinata was just about to join as well, her midsection being just as swollen as the one of the other two. "I can't wait for our first children to be born, Naruto-kun! I want at least ten children!"

"Not so fast, young lady." Tsunade interrupted while clinging to Naruto's shoulder. "Naruto knocked ME up first, so I'm the first one who gets a second batch, you got that?"

"Exactly!" Shizune chimed in. "And after that it's my turn!"

All that Naruto could do was to let out a sigh, just like he had done on his eighteenth birthday. But instead of sadness and disappointment, he was filled with determination. After all, a student would never be truly done with learning.
