Work Text
The Vault-Tec corporation designed the Vaults that protected America during the nuclear crisis. In addition to providing sustainable living solutions for their residents, many of the Vaults also served as laboratories for a variety of social experiments. Vault 99 is just such a Vault.
I don’t want to set the world on fire. I just want to start a flame in your heart.
The Vault door is bigger than I expected.
I suppose it makes sense. There were pretty large pieces of equipment in the Vault, which was itself quite sizable. One thousand people were brought here originally, and now our population is nearly twice that size. That requires a lot of infrastructure.
“Now, it’ll take your eyes a few moments to adjust,” Overseer Grier says. She looks kindly at me, placing her hand on my back. Her Afro is beginning to turn gray in some spots, and her dark skin is becoming slightly wrinkled, but she still looks strong and beautiful. “You haven’t gone blind. Just give yourself a little while to get used to it. You’ve never actually seen the sun, after all!”
“I brought sunglasses!” My sister, Mary, says. She hands me a pair, then whips another pair onto herself. “No solar radiation is going to mutate these pupils!”
Mary looks a bit absurd. It’s not her looks, as her golden hair, green eyes, and creamy skin are all beautiful. It’s not her size either. At roughly four and a half feet tall, she is an average height for women in our Vault. She’s even a hair taller than the Overseer. And, like the other women in our Vault, her breasts and ass are very large, which is necessary for childbearing. The absurdity of her appearance is more in the size of the gigantic backpack strapped to her back. It looks like she has packed every item in our family’s apartment.
Overseer Grier laughs.
“Preparedness is imperative, Mary, but it will only get you so far in the Wasteland. It’s why having Benjamin take the lead is so important to your mission.”
“I know,” Mary says. If it were anyone other than the Overseer speaking, they would have just been on the receiving end of a classic Mary eye roll. But she restrains herself out of deference. She may be eighteen now, but she still has a lot of learning to do. “I support Benji! No one wants him to succeed more than I do. I’ve got as many supplies as I can carry, and I’m ready to drain his balls whenever he needs!”
Overseer Grier nods.
“That’s what I like to hear, Mary. Speaking of,” the older woman unzips the collar of her Vault-Tec jumpsuit a bit. “Do you need any relief before you get going, Benjamin?”
“Sure thing!” I say, unzipping my own jumpsuit as well.
My body, like the body of all men in our community, is much larger than the two women beside me. I’m about seven feet tall, and covered in thick slabs of densely corded muscle. My hair and eyes match my littler sister’s, but that is where our similarities end. I’m twenty-two years old, and people have been confusing me for our father for years. He and I are very physically similar, all the way down to the size and thickness of our thirteen-inch cocks.
“He pumped me full an hour ago, Madam Overseer, I promise!” Mary says nervously. “I wasn’t ignoring my responsibilities.”
“There there, dear,” Overseer Grier says softly. She wriggles her shoulders out of her jumpsuit, exposing her large, though slightly sagging black breasts. “I know how horny this young man gets. I haven’t forgotten the reports from the Vault’s laundry staff about the crustiness of Benjamin’s socks when he was growing up. Even with such a devoted sister, an hour is quite a long time for him to go without a release.”
The Overseer kneels, and I shove my cock between her tits. She looks up at me in adoration.
“That’s it, my sweet boy. Take whatever you need. You’re the hero of the Vault, after all. It’s my pleasure to give you all the satisfaction you require.”
I glance over at Mary.
“Sis, would you mind?” I motion with my eyes.
“Oh! Of course, Benji! Sorry I didn’t get down there sooner!” Mary practically dives headfirst into my ass cheeks, pressing her tongue as deep into my hole as it will go. Her tongue writhes furiously inside me as Overseer Grier milks my cock with her elderly udders. Getting pleasured from both sides quickly brings me to the edge.
“I’m close!” I grunt.
“Right here, sweetie,” Overseer Grier points to her forehead. “I want the whole Vault to see that I helped our hero just moments before he set out on his quest.”
“Mmmphm!” Mary calls from behind me, giving a thumbs up before playfully squeezing one of the Overseer’s breasts.
I blast.
My cum is hot, thick, and gooey, splattering on the Overseer’s forehead, into her hair, and onto her face. Ropes of my sperm thoroughly coat her entire head, slowly dripping down and landing on her big breasts. There is probably twelve ounces or so this time, which is a pretty standard load for me. Spraying our Vault’s leader with it feels absolutely wonderful.
Twenty-five years ago, before Mary or I were even born, Overseer Grier had demonstrated her capability to be the next Overseer by successfully draining the balls of all seven of the Vault’s breeding men (our father among them) for seven days straight. Every prospective Overseer must attempt the Seven-in-Seven, but when the other candidates couldn’t handle it, it was clear that Ms. Grier deserved to become our leader. And now, twenty-five years after that fateful week, she shows that she’s still got it.
“Well done, Benjamin!” Overseer Grier smiles. “It must have been a week and a half since I last had you cumming for me. I’m sorry that it’s been so long since I’ve been the one to service your cock personally, dear. When you and Mary return from your quest, I will be sure to dedicate a full forty-eight hours to giving you my holes. How does that sound?”
I nod, zipping myself back up. Mary stands, wiping some drool from the corner of her mouth. She reaches out, scooping a glob of cum from the Overseer's breasts, then sucking her finger into her mouth.
“Ready?” Overseer Grier asks. She doesn't bother to zip up or clean herself. It's common for the women of our Vault to display their usefulness in such ways.
I glance at my sister, then offer her my hand. She smiles, then gives it a reassuring squeeze.
“Ready.” We say in unison.
“What are the rules?” Overseer Grier asks.
“Don’t cause any unnecessary harm.” Mary says.
“When harm is necessary, don’t hesitate.” I say.
“Accomplish the quest, then return home.”
“Don’t drink the water.”
“Don’t eat the food.”
“Don’t do the drugs.”
“Don’t fuck the holes.”
“Don’t listen to the radio too loud.”
“Don’t run out of ammo.”
“Don’t get killed.”
“Stay away from Yao Guai.”
“Stay away from large population centers.”
“Stay away from unfamiliar flora and fauna.”
“Keep your PipBoy on.”
“Keep your genitals clean.”
“And don’t tell anyone about the real ages we start doing sex stuff in the Vault.” I conclude.
“Well done you two,” Overseer Grier applauds. “That last one could be more important than anything. Before the war, society had a lot of problems with the ways that we so commonly do things nowadays.”
“Did they have to wait to start watching the pornos until after they were se-“
“No age!”
“Did they still get tag teamed by their parents for their birthday once they turned el-“
“Don’t say it!”
“What about a growing girl’s daily drink of cum starting at age ni-“
“None of it!” Overseer Greer looks exasperated, then she sees the way Mary and I glance at each other with bemused smiles. “Oh, I see. Very funny. Here I am, dripping in your cum because I actually care about fulfilling my responsibilities for this community, and you two stand there like jackasses and make jokes!”
“Sorry Overseer,” we say, acting properly chastened.
“It’s not a game, or a joke out there.” The older woman explains. “It is a dangerous place. It’s been nearly forty years since I accompanied my brother on his quest. I think you have both been taught about the disastrous consequences that had on our community?”
“The medical office said that the problem was less about the venereal diseases that you both spread to pretty much every single Vaultdweller, and more about that year’s epidemic because everyone had already used up most of the antibiotics.” Mary answers.
“That’s right. Thankfully, everyone is all fine now and our supplies are back to normal, but we made a big mistake. Don’t follow in our footsteps. Benjamin, why do we send you on your quest?”
“To provide for the Vault.”
“And Mary? Why do we send you alongside your brother?”
“To be his cumdump.”
“That’s right. There is no need to shove that wonderful cock of yours anywhere other than your beautiful little sister, is there, Benjamin?”
“No, ma’am.”
“Atta boy. You’ve been pumping this sweet girl full for at least ei- well it’s not important how long. The important thing is that you both get the quest accomplished, return safely, and bring glory to us all.”
Overseer Grier pulls us both into a big hug, then gives each of us a slow, sensual tongue kiss. Mary takes the opportunity to steal a few more finger-fulls of cum.
“Be thinking about which hole you’d like to start with when you get back, Benjamin.” Overseer Grier winks. Then she walks over to the control panel and presses the large red button.
The whir of the door mechanism fills the antechamber. My heart is racing. I feel Mary slip her hand back into mine. I can’t tell whether it’s because she sees that I’m nervous and wants to comfort me, or because she is scared and wants her big brother. I’m not sure it really matters. I’m glad that I’m not doing this alone, and even more glad that my sister is the one who’s here with me.
The door slowly begins to roll away, revealing a long, dimly lit tunnel.
“Our hopes go out along with you,” Overseer Grier calls to us. She waves, sending some of my cum flying onto the metal catwalk.
“Let’s do this,” I say, squeezing Mary’s hand. Together, we begin to walk down the tunnel.
After a few minutes, we hear the Vault door shut behind us. It hisses as the air vents purge the outside atmosphere.
“Just us now, big bro,” Mary says. “We need to do a good job for everyone back there.”
“Of course. But don’t you think that we can do a good job without following every single one of the rules?”
Mary looks up at me mischievously.
“You think it’d be a good idea to run out of ammo? You interested in tangling with a Yao Guai?”
“Not those ones, dummy,” I tease. “I mean… don’t you want to see the population centers? Maybe try some of the drugs?”
“I think you just want to fuck some of the holes!” Mary taunts. “What? Is your little sister not enough for you? You’ve been going balls deep in me ever since I was se-“
“I think the ages thing may actually be a good rule to follow,” I say. “If the Overseer is right, we don’t want to draw unnecessary attention to ourselves. I’m not exactly the biggest guy around. I can’t be sure that some street tough won’t want to try to beat us up if he learns how long our family has been sexually active.”
“You’re not that small! Just because Dalton Daily is eight feet tall, that hardly makes you a shrimp. Besides, you won last year’s wrestling championship. Not bad for someone as short as you!” Mary has always been such a supportive sister. “So how about you stop moping around and tell me how you plan on fucking these Wasteland holes without causing a venereal disease crisis once we get back.”
“We’ve got more StimPacks, RadX, and RadAway than we know what to do with,” I explain. “If we dose ourselves up well beforehand, then take our medicine immediately afterwards, I bet we can have some fun without anyone noticing when we’re back.”
Mary considers it.
“Let’s do it! I doubt any Wastelanders will be able to compete with you and Dad, though. You two have been giving me and Mom all we’ve ever needed for over a de- for a long time. I know that men need variety, but I just need you, big bro. So if it doesn’t work out the way you want, I’ll still be around to keep you drained.” Mary raises my hand to her mouth and gives it a gentle kiss. “Still, it’d be hot to fuck some Wastelanders together! And I wonder if BuffOut is really as intense as the medical books say it is!”
We continue walking for another few minutes, then come to a steel door.
“This is it,” I say.
“Yep. You ready?” Mary looks up at me sweetly.
“Let’s fucking do this!” I reach for the door handle.
“Wait! Don’t forget your sunglasses!” Mary points to the pair she had given me. I quickly put them on. Then I open the door.
The light is brilliant.
Even with sunglasses, the sun pierces my corneas, causing me to wince in pain. I hold my arm up to block its light, and Mary does the same. I look down at the ground, willing my vision to adjust. After what feels like a long while, I begin to be able to move my head around and take in our surroundings.
“Holy fucking shitballs!” Mary gasps.
I look around, and my jaw drops.
When you’ve spent your entire life inside a Vault, confined spaces become the norm. Even though I’m only seven feet tall, that’s still enough to hit my head on most of the doors. My feet have been hanging off the bed that Mary and I share since I hit puberty. But all I can see, for miles on end, is wide open space. The sky is so far above that I can stretch my arms all the way up and still not come close to touching the top. There are no hallways or narrow staircases or cramped rooms in sight. Everything is open.
The information provided to us by the Questing Committee told us that Vault 99 is located in what was once called the Hudson Valley in an area previously known as New York. Back before the bombs, a person could have taken a train and been in New York City in less than thirty minutes. Now, New York City and its surrounding area is called the Empire Wasteland, and what was once the greatest city in the world is almost entirely rubble.
But that is far away from us.
Here, on the top of a high hill, we can see nothing but wilderness. The trees are shriveled and barren, and there doesn’t appear to be much foliage, but we can’t see a single building in any direction. It feels like it’s just us, alone in the great wide open forest.
“Hey, Benji,” Mary says mischievously. “How about we start this quest off with a nice fuck?”
I turn to her with a smile, and see that she’s already removing the straps from her backpack. Her eyes are bright, and I can see by the way that she’s biting her lower lip that she’s hungry for me. I watch as she slowly unzips her jumpsuit, revealing her enormous, supple breasts. Mom’s are bigger, but for Mary’s age group, she’s got the biggest tits around.
I quickly toss my own pack to the ground, then practically tackle my little sister. She fumbles for my zipper, giggling as I kiss her neck and nibble her earlobes.
“Nothing like a good, old fashioned brother fuck to start things off right!” She laughs, stroking my rock hard cock and rubbing the head up and down her hairy slit. I can tell that she’s teasing me, but I don’t want any foreplay. I grab a handful of her hair and yank on it, causing her to moan and lose focus. Then I thrust my hips forward, shoving myself deep inside her sopping wet cunt.
“No fair,” she cries as I begin pumping away at her. “It’s not my fault I’m so much smaller than you!”
“Then don’t be such a little tease,” I grunt in her ear.
“Isn’t that what little sisters are for?” She moans.
I don’t answer. Instead, I begin to assault her pussy, pounding it roughly with my large cock. I may be scrawny compared to some of the other guys my age, but I’ve always been hung. Just like our dad.
“That’s it, Ben! Fuck me! Give me that cock, my hero of the Vault!” Mary wails. She clings to my immense shoulders, her body quivering in a near constant orgasm. The women in our Vault never take much stimulation to cum, and both Mary and our mother are considered nymphomaniacs around our community.
“You like this pussy, bro?” She pants. “You like fucking your sister in the great outdoors?”
“I fucking love it,” I growl in her ear.
“Then fill me up, Benji. Pump me full of your load.” Mary grabs my head and turns it towards her, then shoves her tongue in my mouth. It’s pretty normal for siblings to fuck in the Vault, but I’m beginning to think that Mary thinks of me as more than just her brother. When I return from the quest and get my breeding authorization, I know that she will be disappointed. It means we won’t sleep in the same bed together, since I’ll have my own apartment. And while I’ll still be able to pound her for a while afterwards, she won’t have much longer before they remove her birth control and assign her to be a breeder in her own right. Reproduction is a serious business where we come from, and siblings are forbidden from fucking once they’re both breeders.
“Please, Ben,” Mary whimpers. “Fill me up. I need you.”
That sends me over the edge.
I slam myself deep into my sister, then begin to spurt my sticky, warm cum deep inside her. It’s a big load, probably sixteen ounces at least. Once I’m spent, I lay there for a few moments, catching my breath on top of her.
“You know,” she says, stroking my hair. “You don’t have to fuck the Wastelanders. We could follow the rules. If you wanted to.”
I lean down and kiss her.
“How about we focus on the quest first, then we can see what fun we can get ourselves int-“
I hear a growling sound coming from nearby. I glance towards the sound, and see a large, hairless mole rat. Its huge incisors are bared, and it stalks towards us slowly. I know from our briefings that they are rarely alone, which means that wherever this creature’s pack is, I can’t see them.
“My guns are in my pack,” I breathe.
“You didn’t keep them on you?!”
“I was a little preoccupied! You’re the one who wanted to get fucked!”
“I didn’t think you’d totally disregard our training in the first thirty seconds of the quest just because you wanted to get your dick wet!”
“You distracted me with pussy!”
“You’re supposed to be the leader!”
“Well, I…”
“My gun is on my hip,” Mary says. “And I can see one more behind you. Shoot the one you see, roll over to your back, and fire between your legs at the other one.”
I take a deep breath. I’ve prepared for this. Marksmanship classes are a part of our Vault’s curriculum starting in Kindergarten. I reach towards Mary’s hip, but find only more of my sister.
“The other hip, jackass! That tickles!” She squirms.
I reach for her other side and feel the cold steel of the pistol grip.
“Hey.” Mary says. I meet her eyes. “I love you. You can do this.”
I grab the gun, yank it free of the holster, then pull it up. The mole rat senses my movement and lunges, but I fire a round into its skull, dropping it to the ground with a wounded screed. I roll over, point the pistol between my legs, and have just enough time to get the other beast between my sights before it leaps. Another shot, and that monster goes down too.
I go to my knee, scanning the area around me. I see a few other mole rats a dozen or so yards away, but they are skulking back towards the tree line. For good measure, I fire a round into the flank of the nearest rat, sending the entire pack scurrying away.
“Are you okay?” I ask, looking down at Mary. Her tits are splayed out, and I can see my cum leaking from her hairy cleft, but she seems to be fine.
“Yeah,” she says. Her eyes have a fear in them that I’ve never seen before. She glances down. “Zip your jumpsuit. Your cock is dangling out.”
I look down and see that she’s right. My large, flaccid member is hanging out of my jumpsuit, shiny with Mary’s juices in the morning light. Together, she and I compose ourselves, then put our equipment back on.
“Don’t fuck me without your gun on you again,” Mary says.
I open my mouth to argue, but then decide against it. I hand Mary’s pistol back to her. My heart is racing, and I feel like the world’s biggest idiot.
“Hey.” Mary looks at me earnestly. She stands on her tiptoes and kisses my cheek. “You did a good job. Thank you for saving me. Let’s both stay focused. We can fuck again once we’ve got some shelter for the night.”
I nod.
This quest may be a bit more difficult than I expected.
----- CHAPTER BREAK -----
Crawl out through the fallout, baby, to my loving arms.
The journey down the hill is not too bad, and we quickly find a road that meanders through the valley. I walk carefully, my rifle in my hands and my pistol on my hip. Mary’s hand is never more than a few inches away from her own pistol, and I know that she has multiple knives concealed in her jumpsuit. So do I, as a matter of fact.
The job of a hero of the Vault is simple: complete the quest, then get back home. It is a role given to only one unproven man every three years. Successfully completing the quest gives that man the right to begin his life as a breeder, meaning he no longer needs to take his prophylactic medication, can live in his own apartment, and can be assigned a wife. Of course, a male breeder is allowed to impregnate any breeding woman he wants, so the role of the wife is focused on the upkeep of the home in addition to procreation.
Breeding women don’t need to go on a quest, as those jobs are reserved only for men and the one woman they select as their companion. Given that there are only seven breeding men at a time, roughly fifty men and boys that either are waiting to breed or are past their breeding stage, and approximately two thousand women and girls in the Vault, it would be impossible for each woman to complete a quest. Instead, women become breeders once they reach the age of twenty. The dream of every man is to succeed in his quest and become a breeder. The dream of every woman is to be assigned to a man as a wife. Only the best, most fecund, most supportive women get those assignments.
Mary wants one.
In an ideal world, I think that Mary would want to be assigned as my wife, but that is not allowed. Given the rates of genetic defects in children borne of incest, our Vault geneticists make sure that there is sufficient ancestral separation between a male breeder and the woman who is assigned as his wife. Of course, since there aren’t many rules about who a breeding male can fuck (and very few enforcement mechanisms in place to stop them from fucking), there are occasional instances of ‘problematic pregnancies,’ but ours is a sophisticated society. We have ways of eliminating those types of problems.
No, Mary is my sister, so she will never be my wife. And given that she’s already eighteen, she won’t have much time left with me before she becomes a breeder herself and we aren’t supposed to keep fucking. But rules, as they say, are meant to be broken.
“What does your map say?” Mary asks.
“There’s some landmark or something maybe a mile away,” I respond. “I guess it’s called ‘The Empire Diner?’”
“Do you think you have to be an Imperial to go there?”
“The Questing Committee didn’t have much information about the Imperials. Even if it’s just for them, don’t you think we should check it out? Maybe someone there has information that could help the quest?”
Mary shrugs.
“You’re the hero. I’m just the cumdump.”
“Well, the hero would appreciate feedback from the cumdump when he asks a question.”
Mary sticks her tongue out at me. I smile.
“Are we going the right direction for the Academy?”
“North. The Academy is still a few days away, but we’re going the right way.”
“Well, maybe it wouldn’t hurt to ask if there’s anything we need to worry about there.”
I nod. Then I look at Mary’s tits. Her jumpsuit is slightly unzipped, revealing a heavy amount of cleavage.
“Can you zip yourself up? Your tits are distracting the hero.”
“You think it’s easy for me?” She asks, closing her jumpsuit. “I’ve been staring at your ass for the last twenty minutes. All I can think about is shoving my face in there and giving your asshole a tongue bath.”
I shake my ass at her.
“Maybe when we stop for the night you can break out the dildo?”
“Don’t tempt me, hero. I may just grab it right now and fuck you right here in the middle of the road.” Mary winks.
“Just save it for tonight.” I laugh.
After our encounter with the mole rats, it feels good to be joking with my sister again, but we also can’t let ourselves get too excited about each other. Joking has its place, but we still need to be vigilant.
Of course, her using a dildo on me isn’t a joke at all. Mary has fucked my ass more times than I can count. Not as many as my dad has, of course, but certainly more than my mom, who prefers to be on the receiving end.
Vault 99 prides itself on being a sexually liberated environment. When we were younger, our mother taught Mary and me how to both give our dad a blowjob and eat our mother’s pussy. My dad and I have been fucking each other for… a long time. And the men’s athletic programs almost always culminate in a group shower where everyone can enjoy each other without the risk of an accidental breeding. My dad is quite a popular guy with a wonderful cock, and most of the men in the Vault agree that I take after him in both personality and appearance, so I have had a lot of fun with many of the men in our community.
It’s the same with the women. Mothers have a responsibility to teach their daughters how to please men, but it’s common for a woman to grab someone they think is pretty and have some no-risk fun. Breeding men are in short supply, so when a woman is waiting for a man, it’s only natural for her to find a woman to play with while she waits. Mary is a beautiful woman and always has been, so she has attracted a lot of attention from everyone since she was… well, since she was old enough.
The walk to the Empire Diner is slow going. Partly, that’s due to Mary’s short legs. She has to take three steps for every one of mine, and her pack is laden with a tremendous amount of supplies. We are also taking longer because we are being more careful. The encounter with the mole rats, while it ended fine for us both, definitely put the dangers of the Empire Wasteland into perspective. So we keep our eyes peeled.
It’s also slow to get there because we are spending a lot of time cataloguing the animals we find. The essence of the quest is to provide supplies to the Vault, but additional information about the Empire Wasteland is also important. We’re tallying the amount of bloatflies, mongrels, and radroaches we see, which takes a while. But it’s vital intelligence that keeps our Vault safe.
Finally, we hear the sounds of activity coming around a bend in the road.
“Wastelanders,” Mary smiles in eager anticipation.
The Empire Diner is a small building. It appears that its facade was once chrome, but the rust has faded its former shine to a dull ochre. By the road is a sign that originally said ‘The Empire Diner,’ but was crossed out. Now it reads ‘The Impure Dicker.’
“Not a lot of points for creativity,” I shrug.
“Yeah? You think they have good schools out here?” Mary laughs. “Come on, hero. Don’t let the cumdump beat to the door!”
Mary takes off, but quickly falls onto her front, sending a bag of rations flying. I stifle a laugh, then hurry to help my little sister to her feet.
“Easy there, cumdump,” I chuckle. “Let’s not make too many mistakes on our first day.”
“I’m going to buttfuck you extra hard for that,” Mary says, wiping dirty from her tits.
“Promise?” I wink.
As we approach the diner, we come upon a large Brahmin laden with sundries. There’s a pair of absolutely filthy people standing beside it, but the grime is too thick to tell if they’re men or women.
“Oh shit! Is that a super mutant?!” One cries.
I turn on my heel, raising my rifle. I’m ready for whatever threat may come upon us, but my heart is racing. Our training from the Questing Committee told us that super mutants were not to be trifled with.
But there’s nothing there.
“Naw, that ain’t no mutie. Look at ‘is clothes! He’s a vaultie.”
“I’ve never seen a regular person that big!” Exclaims the first person. I’m beginning to think it’s a woman, but I still can’t tell.
“He ain’t regular, I said! He’s a vaultie! Prolly grew up eatin’ real food and drinking clean water.”
“I seen a vaultie before, and he weren’t that big!”
“He’s got a full head o’ hair, you dumb cow! No mutie has hair. Plus wise, they’re all green. Does he look green to you?”
We’re now nearer to the pair, and I can tell it’s a man and a woman, but their filth and stink are both so extreme it’s impossible to determine their age.
“Good day!” I say, trying to make my voice sound authoritative. I hear Mary snicker behind me. “We are Vaultdwellers, here on a quest.”
“Oh, a quest is it? Well excuse us, your knightliness. If we’d’a known you was questin’, we’d’a had the whole welcome wagon out for ya.” The man laughs.
“You sure you ain’t a mutie?” The woman asks fearfully.
“Yes, I… I’m sure. I’m a person. I know I’m a little bit on the scrawny side, but I-“
“Scrawny!” The man laughs. “Boy, you’re the biggest human I’ve ever seen. Prolly even bigger’n some o’ the muties round here. I bet you could rip a mirelurk in two with your bare hands.”
“Oh, come on,” I say, slightly embarrassed.
“I mean it! Biggest got damn person I ever saw. This yer girlfriend? I bet you rip her in two every time you get a hankerin’ in yer nethers!” The man eyes Mary lasciviously. “Though with tits like those, I bet she can handle it!”
“I can handle it, thank you very much!” Mary scoffs. “It just so happens that he fucked me less than an hour ago, and I’ll have you know that my brother here is the best-“
“Brother!” The woman wails. “Did she just say she fucked her brother?!”
“Sounded like it.”
“What’re they doing up in that vault that yer fuckin’ each other?”
I glance at Mary sternly.
“Don’t pay any attention to her, she’s just my… companion. Not my girlfriend. And not my… not my sister either.”
“Still fucked her though?”
“I hardly see what that has to do with-“
“He fucked her alright,” the man nods. “Bet them titties was bouncing all over the place, too. You got a big pecker, vaultie? Bet you got yerself a big pecker.”
“Well, as it just so happens, I-“
“Are we allowed to go into the diner?” Mary interjects.
“The Impure? Sure y’are. Open to all that’s wanting to go in, I suppose. Though I’d have to warn you, the folks in there are all hopped up on UltraJet, and they’ll want a piece or two of them titties. That pecker too, if it’s a biggun. Bet you got yerself a biggun.”
Mary nudges me.
“Drugs! Sex!” She hisses.
“Not sure what drugs are but there is definitely a lot of sex. Plus they’re all hopped up on chems,” the woman agrees. “But I reckon that you two’d be a little disappointed by the selection. No one round here is quite as… pristine as you two.”
She couldn’t have known it, but that was exactly the kind of answer Mary and I had been hoping for.
“Thank you!” Mary says. “We appreciate your kind help. Is there anything we can do for you?!”
I nudge Mary. This is not the time to offer our aid to strangers. We have a quest. Plus, there are drugs and sex to be had inside. Although it seems like we aren’t as clear on some of the terminology.
“Well, I guess I wouldn’t mind gettin’ a look at yer titties,” the man says, rubbing his grimy hands together.
“Or yer pecked, big guy!” The woman calls.
I make eye contact with my little sister, who shrugs. Nudity isn’t a problem for the people in our Vault. Almost every person we know has not only seen us naked, but been involved in some sort of sexual activity with us. I unzip my jumpsuit, hearing Mary follow suit beside me.
“Got damn!” The two people shout. “They must make people different where you two come from.”
“That cock’s gotta be bigger’n my arm!”
“My arm too. And them titties are bigger’n my head!”
The two stare at our bodies for a few moments, their eyes wide. After a while, we zip ourselves back up.
“Well, thanks again!” Mary says as we move towards the door. “Have a good day!”
“Tolja he had a biggun.”
“I never said he didn’t!” We hear as we walk away.
I push the dilapidated door of the diner open, and am immediately hit by a powerful stench. Whatever is going on here reeks. The inside is dimly lit. I remove my sunglasses, then wait for my eyes to adjust.
Inside, there are benches with tables between them, and a long bar with stools. It would be reminiscent of one of the diners back from before the bombs fell, except that just about every surface is covered in a layer of dirt that looks like it would take years to clean off. As we move further into the building, we begin to notice the people occupying it.
Everyone is staring at us.
There is a couple in one of the benches near the door. They’re both naked, clearly in the middle of coitus, but they’re stopped and looking at Mary and me. Another couple is laying on top of the bar, then man clearly moments away from snorting some strange substance off the small breasts of his partner, but stopped. In a corner, there are three people going at it without any notice of us. Two men have a woman sandwiched between them, pounding her ass and pussy together. The crazed look in their eyes definitely seems unnatural.
“Uh, hi,” I say, offering a small smile to a man with his hand on a dingy bottle of liquor. “We are not from around here. Is there any person or robot that can help us with some information?”
The man with the bottle blinks slowly, as if it takes him effort. Then he turns in towards his diner bench and gives the bottle a healthy quaff.
“Hi there!” Mary says to the couple on the bar. “What is that purple stuff? What does it do?”
“It’s uh… I’m not really…”
“Is that guy half super mutant?”
Mary shakes her head, her blonde curls dancing beautifully in the dim light.
“Of course not! Why do people keep asking that?”
“Cuz he’s a dozen feet tall.” The woman lying on the bar says.
“What?! No he’s not! He’s only seven feet, two inches. I don’t think I’ve ever heard of a person growing taller than eight and a half.”
“They can grow taller if they’re half super mutant,” the man says, snorting his powder.
“What is that stuff?”
“Jet,” he grunts. “Well, the powder that’s in a canister of Jet. The inhaler version is better, but you can’t do an inhaler off a hooker’s titties.”
“Can I try?”
“Not for free.”
“I’ll show you my tits.”
The man hands the used straw he was just snorting out of. Mary takes a steadying breath, then winks at me. She unzips her jumpsuit for the second time in as many minutes. The man whistles in appreciation, then shakes a bit more of the powder onto the woman’s breasts. Mary likes the straw up, then gives the line a powerful snort.
“Fucking Assfuck!” She yells, throwing her head backwards. This motion causes her exposed tits to hit the man in the face, which he does not seem to mind.
“You okay?” I ask.
Mary blinks a lot, then works her jaw open and closed in a weird manner. Then she glances at me with a smile.
“Get that cock out.” She runs towards me, her tits flopping with each movement. As she reaches me, I grab her head to hold her in place.
“How about we do what we came her to do first?” I say.
“I’m doing that! We came here to get high and fuck! I’m high, now I want to fuck!”
I glance over at a man who is seated casually at the bar eating a strangely colored slab of meat off a plate. He looks at Mary.
“Doesn’t seem like your girlfriend does a lot of chems.”
“I’m not his girlfriend, I’m his sis-“
“Sustainability advisor!” I finish instead. Mary takes a step back, grabs her huge tits, and shakes them into the direction of the guy with the bottle. “She’s my sustainability advisor. I’m on a quest to find some information and supplies for our Vault. Do you… I mean, if it’s not too much trouble… could I ask you some questions?”
“Depends on how many caps you got.” The man saws into his meat. It looks like it is something that did not come from a mammal.
“Caps?”
The man turns. I can see that he’s a hard looking guy with a crooked nose and a scar on one cheek. I also see that he has a pistol on his hip.
“Caps. Nuka Cola. Y’know, fuckin’ money.”
“Oh! Yes, as a matter of fact I do.” I reach into my pack and pull out a large sack laden with hundreds of bottle caps. The man’s eyes go wide.
“How many would you like? Is it a per-question thing, or is it time-based?” I ask.
“I can toss you some vag if it’ll sweeten the deal,” Mary slurs. She’s climbed on top of the bar and is humping her clothed body against the man that gave her the drugs. He wastes no time inserting himself into the woman beneath him.
“Toss him vag? What are you saying?!” I roll my eyes. I grab her by her pack and haul her back onto the floor. “Sir, we’ve got a long way to go before we get to the Academy. If you could please just-“
“Did you say the Academy?” A voice from the kitchen asks.
We hear footsteps, then see the flimsy door swing open. A ghoul, his skin desiccated and stretched tight looks at us. He has an apron and a paper hat.
“You two, come with me.” He rasps.
“Mark, come on, man!” The guy with the scar says. “I was just about to make a big score!”
“I’ll fuck a ghoul, I don’t care!” Mary says frantically. Her eyes never remain in one place long, and her entire body seems to be vibrating. Her huge breasts are still wobbling out of her jumpsuit. “I’ll slurp down that ghoul dick no problem. Maybe there are more and I can have them run a train on me!”
The kitchen was clearly once something impressive. Large steel devices along the floor and huge steel sheeting lining the ceiling. Now, what appears like it used to be an enormous griddle now has a small gas-powered range on it.
“First time out of Vault 99, huh?” The ghoul asks. He pulls a pack of what look to be cigarettes out of his apron pocket, extracts one, then leans his head to the burner of the stove to light it. He takes a deep drag, then hands it to Mary. “That’ll put her on a bit more of an even keel.”
Mary puffs on the cigarette-looking thing, then begins to hack and cough. But she takes another puff, and coughs less.
“I think just about every quest from 99 starts by coming through here,” the ghoul says. “I’ve never had a Pip-Boy myself, but I think your maps show this establishment as the nearest one?”
“That’s right,” I nod.
“And you thought you’d come in here, get a little high, get a little laid, and then go about your business?”
“More or less,” I say. Mary sucks at the cigarette thing more, her eyes becoming less frantic.
“You all love fucking, huh?” The ghoul scoffs.
“Fucking is the best,” Mary shrugs. “If you think otherwise, it’s just because you haven’t been fucked right.”
The ghoul laughs at that. It’s an odd sound, like a bird call or a wounded animal.
“That’s funny. I like you. As you’ve seen, lots of folks in the Wasteland agree with you.”
“Not you though?” I ask.
“My dick fell off during the process of becoming a ghoul,” he explains. “Same with all the hair and every ounce of fat on me. My skin is stretched tighter than a drum. For the last two hundred years or so, I’ve been little more than a walking corpse.”
“Shit.” Mary says. Her head lolls a bit as a result of the drugs. “No fucking for two hundred years? I’d die.”
“Dying is both easier and harder than it looks,” the ghoul shrugs.
“What’s your name?” I ask.
“Y’know, I’ve seen a lot of people from 99 stop in here. You’re one of the only ones to ever ask my name. I think the last one was probably twenty years ago. A woman named Margo who was traveling with her brother.”
“That was our mom! Her name is Margo!” Mary says excitedly. It seems like the two different drugs are impacting her sporadically.
“Well, I see where you two get your manners,” the ghoul shows his teeth, making him look fearsome. But I think he’s trying to smile. “I’m Gus.”
“Ben,” I say.
“And I’m the cumdump.” Mary says. “But you can call me Mary. It’s nice to meet you, Gus.”
“What’s your quest?” Gus asks.
“The Academy supposedly has a lot of stuff that we need. I don’t know all the details, but it’s apparently a place where you can get plants? Real vegetable seeds, real fruit trees. Stuff like that. Our botanical garden is running low on sustainable crops.” I explain.
Gus takes the smoking thing from Mary, the puffs on it pensively.
“The Academy is not the kind of place the two of you ought to go.” He says. “People from 99 are usually trying to get to the community in Woodbury Commons or something. Trade one of your water purifiers for medical supplies or something. But the Academy is not safe.”
“Why not? What goes on there?”
“Military training. The Empire’s school for its soldiers. I guess it’s possible they do other research there too, but it’s mostly the heart of the Imperial Army. They don’t look too kindly at big guys like you with guns.”
“Why is the Empire bad?” Mary asks.
“Didn’t say they were,” Gus replies. “Law and order have their upsides. Raiders are mostly confined to the mountains, trade moves across the river pretty easy. Not too bad. But they are intense. And they don’t like outsiders.”
“But… my quest is to go there and get the stuff. My Vault is counting on me.” I say softly.
“If they can survive this long, they can do it without your help. My advice? Find some new clothes, find a new community, and start making a life out here, far away from any of that shit. The Academy is where death is. Plain and simple.”
“But our Vault…” Mary breathes.
“Vaults all store secrets. That’s what makes them vaults. 99 has plenty of its own, believe me.” Gus shrugs.
“What do you mean?”
“You two noticed yet how you look different from the other folks in the Wasteland?” We nodded. “You wonder why?”
“We get to eat more calories with less radiation, I guess,” I shrug.
“People didn’t even get as big as you before the bombs fell, son.” Gus says.
“How do you know?” Mary asks.
“Because I was there. I’m actually relatively tall for the people back then. And you’re probably a foot taller than I am. That isn’t the food. No, it’s all Vault-Tec.”
Mary and I look at each other warily.
“So… what does that mean for us?” Mary asks.
Gus sighs.
“Not sure it really means anything right now. Only that you and your brother are the product of centuries of genetic engineering. Don’t know if that is a positive or a negative. You both seem healthy, certainly very exaggerated proportions, but otherwise I imagine you’re both doing a megaton better than the folks out in the diner.”
“What’s your point then?”
Gus stands, moving towards the back door.
“My point, is that you should take your healthy, obsessively designed bodies and go live life with them. You don’t owe the vault anything, and you don’t need to go to the Academy. You can just go live. It’s all anyone out here can hope for.”
He opens the door, pointing towards the wood line.
“I’d leave out the back, if I was you. I’m guessing that the chem-addled sex fiends in the diner are going to want every last cap, bullet, and StimPack you’ve got. You can probably handle the whole lot of them, but that’s my customer base. Leave before anyone starts trying to take anything from you. Woodbury Commons and the Academy are the same direction: north.”
“Thank you, Gus,” I say, hefting my pack.
“Don’t mention it, Ben. Least I can do. Your mom was, well she was kind to me back then. I’m old enough to believe that one good turn deserves another.”
I leave the diner, turning to check the perimeter. Nothing.
“You’re a sweet man, Gus,” Mary says. She stands on her tiptoes and kisses him on the cheek. “If you had a cock, I’d offer to suck it. Want a peek at my tits for your trouble?”
Gus gives his raspy, violent laugh.
“How about you just take it easy on chems for a bit, huh? Can you do that for me?”
“No promises,” Mary winks. “Bye now.”
“Bye, Mary.”
As the door shuts behind us, Mary and I glance at each other.
“What do you think?” I ask.
“You’re the hero. I’m just the cumdump.” Mary says with a soft smile.
“I want to know what you-“
“Ben,” Mary takes my hand. “What I’m saying is that I go where you go. Whether that’s the quest, the Vault, or anywhere else in the world, I’m with you. For all of it. Okay, big bro?”
I smile.
“Now let’s go find some shelter for the night. I’m dying to fuck. Those chems made me so fucking horny!” She laughs.
An hour or so later, Mary and I find an abandoned house on a lonely street. After thoroughly checking it for creatures, we make our way to the top floor. There is an old metal bed frame with a dingy brown mattress.
“Not a bad place to buttfuck your brother in, if you ask me,” Mary says playfully. “You want to eat dinner before or after?”
“After,” I say.
“That’s what I was hoping you’d say.” Mary laughs.
We both toss our packs onto the floor, unzip our jumpsuits, and get completely naked. Mary unzips a pocket of her pack, producing a large, veiny, curved strap-on dildo. Dad and I have had it inside us countless times over the y… times we’ve spent with Mary. My cock, dad’s cock, and Mary’s dildo are all about the same size, which means that Mary looks absolutely absurd whenever she straps it onto her tiny, voluptuous body.
“The classic conundrum,” Mary sighs as she fastens the dildo to her hairy pelvis. “If I could trade my pussy for a cock, then I’d finally be able to get a chance to feel what it’s really like to fuck you. But then I’d lose out on the feeling of getting fucked by you. What’s a girl to do?”
“Since when have you been a girl? I thought you were just the cumdump?” I joke. I lean down and flick my tongue against Mary’s nipple, causing her to moan.
“Very funny, hero. Now get on all fours and shove that ass in the air. Little sis is going to pound your prostate.”
I ignore her for a second, instead pressing her against the wall. I look down at her, and see her glistening eyes look up at me. My cock is rubbing against her dildo, and I can see all the love in her eyes.
“Did you think about it?” I ask, gently massaging her enormous breasts.
“Of course I did. I’ve been… it’s an idea that crossed my mind a while ago. Long before we left.”
“So that means that you want to do it?”
“It means that I like the fantasy of it. I’m not so sold on the practically yet. I mean, we’d be able to pull it off easily. Lots of heroes and cumdu- companions, whatever, don’t make it back. But it’s saying goodbye to Mom and Dad, all our friends, all the amenities of the Vault, and the life we grew up with. Forever.”
She cups my balls, rubbing them gently.
“I don’t think it’s a secret that I love you a bit more than a sister is supposed to love her brother,” Mary closes her eyes, and I see a tear run down her cheek. “So yeah. Do I want to throw our prophylactic pills in the river, find a place to live, and give you children like a wife is supposed to? Fuck. Yes. But we’ve also got other people counting on us. People we love, who love us. And we’re young! We’d be able to keep fucking back in 99, at least for a while. Then who’s to say that your wife or my husband wouldn’t end up being our happy love story, and this adventure will fade away as the time we killed some weird bugs and got some vegetable seeds? We have our whole lives ahead of us, Ben. As much as I want to run off into the sunset with you, isn’t it better to focus on survival and take what we can get otherwise?”
I wipe the tears from her face with my thumbs. I lean down and kiss her gently.
“I love you, sis,” I whisper.
“Don’t say it like that,” Mary sobs. “You know I mean it differently. Please don’t say it to me unless you mean it my way, too. You’re a great brother, Ben. I’m a lucky girl. But my poor little heart won’t be able to handle it if you tell me that without meaning it the same way.”
I look down at her, seeing the seriousness in her eyes. I nod.
“Fucking chems!” Mary forces a laugh. “I must either still be high or coming down, but these emotions fucking suck!”
She slaps my bare ass.
“So how about you get on all fours, stick that ass in the air, and get ready for a prostate massage!” She pushes inertly against my chest. I’m so much bigger and stronger than she is, it would be impossible for her to make my body do anything I didn’t want to. But when it comes to the occasional assfuck? I’m more than happy to give my sister the reins.
There’s a cracked mirror on a dresser by the bed. Through it, I can see the reflection of the pair of us. It looks pretty silly. Mary is so incredibly small, and yet she’s behind me, rubbing her dildo up and down my asshole as she spits on it. In school we learned that the dogs from before the bombs fell were a wide variety of sizes, but still genetically the same species. This image in the mirror makes me imagine a Great Dane getting fucked by a corgi.
I let out a deep groan as I feel the dildo push into me.
“God, your ass is so sexy, bro!” Mary says. One hand grips my hip while the other jerks my cock.
“Fuck me, sis,” I grunt. “Fuck my ass!”
She does.
Our family is no stranger to mixing things up in the bedroom, and all four of us are quite skilled at giving each other what they want most. Mom, for instance, doesn’t enjoy being dominant, likes being called filthy names, and cums hardest when she’s a second or two away from being choked unconscious. That’s a big difference from Dad, who likes feeling worshipped, dislikes losing control of the situation, and cums hard whenever he feels his partner start to cum too. Mary, at only eighteen, has already discovered more of these familial peccadilloes than I have, and no one is better at giving us what we crave than she is.
So when Mary fucks me, she knows exactly what I like. She starts to furiously hammer into my ass while her hand jerks my cock ferociously. She lays on top of my back so she can get my ear into her mouth.
“You like getting fucked, bro?” I says in my ear between nibbles.
“I fucking love it when you fuck me, sis,” I groan.
“Right back at ya,” she smiles. “Flip on your stomach. I want to suck you while I fuck you.”
One of the best parts about the size differences between men and women in our Vault is that it allows for more unique positions. Because Mary is so small and my cock is so big, it’s only a few inches away from her mouth when she’s fucking me missionary. All she has to do is lean down slightly, and she can pump my ass while I pump her mouth.
“I’m going to cum, sis!” I moan. Mary responds by moving her hips faster and sucking my cock deeper into her mouth. She reaches her hands as far as she can get them, which for her size is just far enough to pinch my nipples and send me over the edge.
I let out a powerful moan, then feel my cock spasm as my cum begins to shoot through it and into my little sister’s mouth. She slurps it all down greedily, continuing to pump her dildo into me and coax as much cum from me as possible.
“Fuck!” She gasps after I’ve finally spent my last ounces inside her. “That was a lot, big bro!”
“I like it when you do that,” I shrug with a contented smile. “It’s a compliment.”
“Well then, thank you very much,” Mary laughs. She tosses her dildo onto her pack, grabs our pistols and puts them beside us, then crawls into the bed to spoon with me.
We hold each other for a long while.
“I’m going to stop taking my pills,” Mary finally says.
“What?!”
“I’m not saying that we need to run away together!” Mary exclaims. “We can still do the quest and come back. But if it takes a while, and you stop taking your pills too, then I can get far enough along with the pregnancy that they’ll have to let me keep it.”
I look at her quizzically.
“That’s a thing that happens! I read about it in old medical books from before the bombs. Pregnant ladies could get rid of them early, but too late and it was more dangerous than it was worth. If you fuck a baby into me soon, and then we do the whole quest and come back, it’ll be too developed for them to get rid of it. It’s a pretty perfect plan.”
I shrug.
“Okay. Well it sounds like it’ll be worth a try. I’ll throw mine away too.”
“Really? No convincing or indecision at all?”
“Nope. I think it’d be hot to see how big your tits get.” I say seriously. “That’s basically enough for me. Sounds like a gre-“
“Muties!” A voice calls. “Where are you?!”
“Come on outta there!” Someone else shouts. “We know you’re in that house!”
“Ain’t no way we can let some fucked up, super mutant, sibling fuckers stick around our Wasteland!” Shouts a third voice.
“What the fuck?!” Mary whispers.
We scramble to get our jumpsuits back on, then get our weapons at the ready. I begin to move towards the window. I’m just about to lift my head up and get a peak when a new fourth voice comes into play.
“Step out of the house in the name of the Emperor!” Comes a loud voice, clearly amplified by a microphone.
Fuck.
