This is a 30-page ($90) commission that I recently wrote.

If you would like your own commission, please message me about it and we could see what we can work out?


Brock liked to think that he lived a relatively normal life. At least that was what he told himself when he was off at college and didn't have to consider the sisters he had back home. When he was returning again, his little twins were once again occupying his mind. The problem was mainly that the two of them were just kind of rough with him sometimes, a bit embarrassing, and always had some new strange games that they wanted to play at his expense. He found himself shuffling lightly as he considered what the next few days would probably be like for him.

The cab finally stopped and he looked over his childhood home, seeing the p[lace where they were both going to be. He sighed lightly and grabbed his stuff, slowly making his way to the door before suddenly an explosive burst of energy interrupted him! Right there, in front of his very eyes, his sister Mary waved at him "Hey, long time no see!" she loudly declared before walking in close for a hug, wrapping her surprisingly strong arms around his waist and wrestling with him ever so slightly. That was another thing about his sisters, they were always rather eager to engage in physical contests even when he really did nothing to suggest that he wanted one. So Brock reached down and rubbed her red hair "Thanks, Mary" he said before she giggled, hooking her foot behind his leg and throwing him to the ground.

Brock rubbed his own head, scraping his blond hair as he looked up the thin bare legs of Mary. she was wearing nothing but a T-shirt and a pair of reed daisy dukes. And those little cutoff jeans were stuffed with a cucumber the size of Rhode Island by the looks of things! That was the other thing about his little sisters, they were both very energetic futa with cocks that completely dwarfed his member. They weren't really ashamed of it at all, which he supposed was good for them, but was often bad for him. Mary looked down from her standing perch and began to tap her bare feet on the ground. This was a sign that she was impatient with him.

"Wow, great throw sis" he said, awkwardly getting up, only to receive a realer hug from her. He was always a bit thin and on the "femmey" side in a few ways, but his sister was still barley up to his shoulder, and herself a bit of a string bean, so it was a bit surreal to have her manhandle him like that, only to move in again for a close hug.

"Mom and dad are at some kind of resort together, it's just you, Jamie, and me for the whole week. Isn't that great?!" Mary said as she grabbed his hand and slowly started pulling him in. he looked at his little sister's strawberry blonde bob cut bounce up and down, trying to avert his eyes from the surprisingly large butt she had hanging halfway out of those low cutoffs. Was mom dominating dad again? Things had gotten...weird in recent years, he had no idea what to think of their relationship at this point. They both seemed vaguely happy, at least as far as he could tell.

"That's great," he said as he was lead into the house, only to have Jamie tackle him again, easily knocking him down and trapping him in her grasp. She definitely did not have a stringbean build, and would probably be described as "thicc" by most of her classmates. Her breasts were big as small melons and currently pressing against his ribcage so hard that he was having some trouble breathing

"Hey Brock, you missed our big 19th birthday party. It was a real banger" Jamie said, turning her head to her sister, who nodded in agreement. Jamie pushed herself up, sitting her skirt on her big brother's stomach as she rocked slightly. She had a sundress on, one that showed off a lot of cleavage and all of her tones arms, as well as revealing her thighs, and speciallly built white panties that held in what looked like a massive soft cock. "Oh, what else...I got my hair done different" she said as she grabbed the two strands hanging over her shoulder, then craned her neck around 'See? It's all short in the back, and I bleached it a lighter shade of blonde" she turned to him again and let the strands go "except the lil tentacles I keep. Those stay pink. She smiled and lightly touched his face "Why have you been so quiet? How si senior year going for the man of the family?"

They were so much less mature, how did his parents change so much in a mere four years "It's going fine. Could you please get off of me?" he said, looking down at her body, then up at her face 'and uhhh, how was your last birthday party? I take it you have no trouble sharing one anymore?"

'Duh" said Mary, somewhat offended as she waited for her sister to get off of Brock so she could help him to his feet, easily moving his entire body with just one of her arms '' I mean, we are not little anymore. We also had a boy girl party. Or well, boy-girl-futa party may be more accurate" the strawberry blonde giggled, turning to her sister and offering a coy smile

"Well, I'd say Mary had a boy party while I had a girl party" the pink-highlighted sister said before slapping her thinner sibling's butt, getting a girlish squeal out of her. Were they thinking what he thought they were saying? It was certainly weird that they would so casually engage in such a salacious dialogue, he was certain that he must be missing some context or something. Brock folded his arms in front of his torso and cleared his throat

"That's really interesting" he began, looking at the two of them start to grab pieces of each other, and their genitals starting to straighten and harden in their pants "Bt I really have to get to bed, I have to figure out some homework and also do some other...stuff"

"You were never much of a liar" Mary said, fists on her hips as Jamie went behind Brock and grabbed a handful of ass. 'But that's probably for the best, having a brother who gets manipulated as easily as you do definitely has its perks, such as our ability to always have a nice willing dolly to play with! Maybe even an incubator some day"

"Incuba-AHH!" Brock felt a hand slap his ass hard, and then pulled his pants down, revealing his blue boxer-briefs,. Both sisters looked at them, and Mary was the first one to actually place her hand on his bulge and start squeezing. He tried to push her off but having her handle him like that just felt too...good

"Hmm, getting excited as easy as any of the boys at school, about as big as any of them, too" Mary said casually as she pumped him through the fabric, expertly handling him into precumming all over the front, subsequent strokes bringing out more than just precum and making him stare down and huff, trying to avoid what would probably be the most embarrassing thing he could possibly do in front of his sisters.

Then Jaime pulled up the skirt of her sundress. Shooting her sister aside before pressing her bulge up against his 'Huh, no comparison" she said, making noen of how her bulge was considerably thicker and maybe half and again as long as his, even through the panties he could tell she was packing an anaconda. But when she pressed her cock against his, he finally felt something that terrified him.

"Wait, are you soft?!" he asked in trepidation, feeling that it definitely was not a solid, rigid cock pressing against him. It wasn't like that at all, it was a relatively loose and snakelike boner that slowly started growing inside of the white cotton

"Oh, I'm sorry Brock" she said, reaching a hand up and caressing his face, bringing his blush out even further "You do really make me excited and all that, I just don't always get worked up as possible in your presence. You are a very sexy boy" Jamie said before pulling him and kissing him on the lips. He tried, fruitlessly, to avoid or at least curve the kiss, but her tongue just went straight in and she grabbed his shoulders for proper leverage as she snuck in more and more, her sister watching the hole thing.

"You know its no fair" Mary said as she got on her knees, watching the dance between the cocks, Jamie's growing to truly monstrous sizes and getting bigger by the minute as she forced her older brother into the embrace "I never got tall enough to just reach up and kiss him like that. I either have to lay down with him or find a step-stool if I want to make my lips go against Brock's" she said, before reaching out her hand sand grabbing both of their asses, getting nice feels as she closed her teeth around her bottom lip and felt herself strain her daisy dukes. She got up and unzipped them, ten other pairs had been ruined by this kind of growth, she didn't want to make it eleven 'Oh that's much better" she muttered as she rose to full height and kissed the breast of her sister before nuzzling her other sibling's chest "are we doing anything else?"

Brock was in a state of shock, unable to properly or logically react to everything that was going on in his little world at the particular moment. He was aware, roughly, of the fact that his sister was pressing her lips against his and something really big and warm and fleshy was rubbing all over his groin and thighs. When his sister pulled her lips from his to dress his other sister, he finally started to think of what was going on.

"Sorry, I never meant to leave you out of any fun" Jamie said innocently as she reached out finger and lightly placed it in Mary's mouth. Brock looked down and saw that Jamie was definitely sporting rather prodigious erection. That was no good, was it? "OOOH" continued his sister 'But I'm sure we'll find something that will be fun for all three of us. Maybe we could do something in the water? Would that be fun?"

"Yes!" Mary nearly shrieked. "Maybe Brock and I could wear matching speedos, even? I bet we'd both look just super handsome in those" The smaller sister said, wrapping her arms around his waist and then looking back at Mary "well, you see, I don't think I really need a bra cus there isn't much to hide, plus I do look totally cute when I'm topless" she said with a smile.

"True" Jamie said, before grabbing both bulges, working them in her grip and making Brock moan and shake "But I think you'd need a speedo with a different sized crotch than his, you know?" Brock felt himself blush in the extreme humiliation of it all. His sisters bot utterly dwarfed his cock, it wasn't even close! Worse yet, they were manhandling him easily, making him so hard in his ants that he was approaching orgasm even lacking skin contact. There was no way this could get any worse... "Beside" Mary said as she reached for his chest and lightly tweaked a nipple "he would look SOOO much cuter in a nice girl bikini"

"Hey!" somehow that was the final insult for him. For whatever reason, everything that came before was acceptable but this was just going too far. "I am the only boy here, I think I can dress up as one, and my little sister needs to wear a top when she gets in the pol" he said, grabbing Jamie's shoulders and looking deep into her eyes "You need to be...modest" he said, gulping. Suddenly he fell arms wrap around him, breasts push on his back,and his body get pulled into a full nelson. He struggled briefly, finding that his curvier sister could hold him like this all day, and also that when he pushed back he got her bulge going directly into his backside, showing off who was the real person in charge of the specific situation. He gulped as he felt Jamie's hand on his crotch again

"You are the boy, huh? Let's check on things" she said, pulling down her panties to reveal her hard cock, she physically tore his undies form his hips before putting them side by side to compare. "No, not seeing it...I look like the real boy here" she wasn't exactly wrong, her schlong was easily twice the length of his, and was making him even harder just from coming into contact with him,a s much as the sensation confused him "Actually I'd say that you are definitely the girl here. You have a little clitty and a cute face"

"Plus" Mary whispered into his ear before lightly nibbling a lobe, breathing her warm breath right down into the canal and licking his face "Either of us could knock you up if we fucked you. You couldn't knock up either of us" she kissed him on the cheek, leaving him feeling humiliated and powerless. He knew of the potency of futa, but to be told he could get raped by one of his own little sisters? Even worse, impregnated and forced to carry the child to term! He wouldn't be able to avoid his humiliation at all if he had to look at that bump every day, or even worse...a the baby he'd have.

"Hey, no!" he said, resisting with all his strength as he felt the bulge of his curvy sister's cock hot dog further and further into his asscrack, feeling like it was several inches thick and long enough to complete choke him. They kept moving their hands all over his body, getting more and more sexual with their touching as they heard him beg for mercy, his tiny muscles doing nothing at all to help him resist his little sisters. He realized that it would be one of the most humiliating days of his entire life, and things would only get worse when Mary finally tore his shirt off and threw him into the middle of the living room. When he looked up. Both sisters were portraying him with prodigious erections, stroking the cocks that extended for 13 inches and looked thicker than baseball bats.

"I want his mouth first" Mary said, looking at him and smiling "I bet he'll use a lot of teeth, and I love the idea that he'll hurt them on my rock hard cock"

"H Mary" Jamie said "You know how much I love taking oral virginities. I mean anal is OK but oral is so much more...intimate? Like he isn't getting anything from it, I am just making him pleasure me. So i want his mouth first. Maybe we could play rock paper scissors for that right?"

"Maybe" Mary said, looking at her brother "Or maybe we could just let him decide. Brock, which one of us do you want shoving or fat sweaty cock into your mouth first? Don't fret about missing out, you'll get plenty of both of us in both holes, we just want to know about what you would like to have FIRST"

Well, neither would be the obvious answer. It would also be the only answer he knew for a fact that neither of them would ever take, they both wanted his mouth so he had absolutely no choice in that matter. He cleared his throat, looking at both hard and dripping cocks as he struggled to figure out how he'd even begin to make a decision like that. Both of them seemed threatening, hard, big, and like they would in his mouth apart. Neither even seemed like it was any bigger or smaller than the other, despite both of his sisters being the same height

A voice in his head told him not to answer, not to play their game, not to let them think that they had control over him when at any time he could shut all of this down simply by refusing to play. But that part found itself mustard as he considered the reality of the situation. His heart was racing and he could feel his asshole puckering. He had never been raped down there before, but there would be a first time for everything. "Uhhh, Mary please" he said lightly, looking at both of them "I Just think that she is going to be a lot more gentle with me than Jamie would be" he twiddled his thumbs and looked to his sides as he heard the sounds of bare footsteps approaching him, both girls taking their time to march with authority

"Oh, I think you chose for the wrong reason" Jamie said, getting behind him as Jamie grabbed his beautiful blonde hair, slowly smearing her cock across his face and leaving a long gross trail of precum. "Mary has always had a big rough streak when she rapes guys, has some philosophy about always making sure that they get what's coming to them or something"

"Well it's true! Men are so entitled, they need a raping, a real raping so that they can finally realize who actually controles their lives" Mary said, her cock now spreading precum all across his forehead. Brock was shaking, almost falling to the ground from the stress of the situation. He realized he had essentially no choice in any of this, but he still felt like it was somehow his fault that he was getting raped. The guy wondered if he had been too tolerant with his sisters. Or too harsh? Maybe it was his fault for ever getting hard from their bullying when he shouldn't have reacted to it at all. Maybe he was just a pervert getting what comes naturally to perverts.

"Ahhhh!" he interrupted his own thoughts with a cream as Jamie shoved her head down his ass, the penetration sudden even if it wasn't severe. He gripped the invading cock as hard as he could, finding that it wouldn't bend away from him at all. On the contrary it accepted his pulsating asshole with a renewed vigor, shooting him full of precum as Jamie slowly slid further down into him

"Our tiny cocked brother sure does make a great playtoy, huh?" Jamie said, giving her sister a thumbs up before returning her hands to her brother's hips, sliding her cock ever further into his ass, making him scream out some more

"Oh yes" Mary responded, halting his scream by shoving her head down his throat, causing him to nibble down on the cock. She was right, her penis was like a rock, he had no interest in ever having his teeth make contact with it again after he discovered that fact. He didn't exactly swish his tongue around to give her as much pleasure as possible or anything like that, but for just a little bit he opened his throat and tried to just accept the second half of his spit roast. "But he's not exactly tiny-cocked, he just has a male's penis. Of course that's small compared to ours, futa usually are much better hung than men are

"I know that" Jamie shot back, her cock sliding ever further into the abused asshole of her poor brother. She interrupted herself with a gasp, loving the sensation of him squirming around her "You are going to make such a cute baby for me!" she said, before slapping his ass hard enough to leave a welt. He moaned into the cock that was choking him, and Jamie took that opportunity to slide in all the way. The bulge in his belly was enormous as he felt himself getting filled up in both ends, Mary's cock inching closer to his face 'But from my perspective" Jamie continued 'is cock is tiny. Because I am a futa and my twin is a futa, so futa cocks are more standard sized by my reckoning

"True" Mary said, leaning over Brock's body and kissing her sister on the lips "I am so excited to see what the baby you leave in his pathetic little body will look like! You gotta give me a turn pretty soon, I like the idea of giving him twins!" both girls laughed hard at the concept, leaving Brock all alone with his pain and terror.

Not only was he getting raped by immediate family, he would be suffering a further indignity. Ever time he felt the slightest movement of the phalluses inside of his body, he would just be that much closer to having to bare the life of their nonconsensual, unnatural union. He fought with his arms and legs, futilely resisting them as they both pulled out approximately half the length of their cocks, then suddenly shoved them back in and filling him up to the brim, precum dripping from his ass, nose, and indeed cock as they filled him up.

Jamie sighed as she pressed further into his asshole "Oh my god, Brock is such a fucking slut!" he more feminine sister declared, feeling herself leaning into the bigger brother "Like damme is he easy to just shove a cock inside of and run with it, you know?" she asked before shooting her hips forward, forcing him to buck as she groaned at him "Little guy is gonna be a great mom once I finally fill him all the way up, though" the busty sister in his ass said, looking down at his bare back and imagining all the awesome sex they were going to have once she really got her hands on him.

"Oh yeah, no argument there" Said Mary as she reached down and grabbed him by the shoulders, forcing him to suck even further on the cock. She giggled as she heard him belch and moan, gag and groan, generally make a complete fool of himself on that hard cock of hers. The precum slipping out of her urethra and into his mouth was probably enough to choke him were she only to spill it more haphazardly, but as she was doing things she manly just made him groan at her. She felt her cock expand even more "Hmm, taking your masculinity may make me grow even more over your stay here. I hope you'd be fine with me having more length" the more tomboyish Mary mocked her brother

"Oh I have no doubt" the blonde, pink-highlighted Jaime said as she shoved herself all the way inside of his ass "That he is going to enjoy our long, hard cocks even more when they get longer and harder" she said as she started rubbing her cock right up against his prostate, making him shriek into the cock in his mouth as Jaime grabbed his hips quite hard and really started fucking him for all she was worth

"Oh, are we putting the slam on him now?" asked Mary in an innocent tone as she reached around and grabbed his abused windpipe, squeezing it as hard as she could and cutting off his already nearly nonexistent oxygen supply as she rammed her cock forward, smashing her balls on his suffering chin hard enough to make him feel like he was going to be knocked out,and started moaning and leaning forward

He felt himself being used from both sides, turned into a veritable sex toy, and somehow finding it in his body to enjoy a lot of what was being done for him. He felt the omnidirectional penetration, confusing him but at the same time bringing him in to enjoy it from a new perspective, forcing him to just grab on with both holes and hope he was going to be fine. The sounds of his sisters moaning and making out on top of him made him more anxious to serve them. He had no idea why he would ever feel that way, but he did, desperately trying to get them to get themselves off inside of his body as he got closer and closer to making both of them cum. He felt a hand firmly, authoritatively smack his ass and a kiss above him pull apart into its constituent sisters

"Hey bro, be prepared for quite the little blast" Jamie said, biting her lip before Mary died the same thing. He felt them pump harder and harder, forcing his body upward as it was supported by only the cocks inside of him and their constantly upward motion, but then suddenly they stopped, still holding him in the air, but now holding him statically. He reached his hands out, feeling the legs in front of him as his feet felt the legs behind him. He was content in some small capacity as he hung there, but then he felt it coming for him. The cocks exploded simultaneously, each one filling him up with glob after glob of hot, sticky cum

He was exploding from mouth and ass, neither hole nearly big enough to hold all of the hot seed he was being filled with, but he was still managing to stay conscious and take whatever he could. They both groaned into him and went even further in their fucking, ensuring that his tortured behind and breatheless throat would stay that way until every ounce of their cockmilk was speiled.

This finally became too much for Brock, and he felt his ass go crazy with desire, squeezing around the cocks as hard as it possibly could as it rhythmically pleasured Jamie, letting her know his body was already subservient to her.. He felt himself shoot his own comparatively minuscule load onto the ground, getting the clearer fluid quickly lost in the massive amounts of sticky white that were going everywhere, making him moan and groan as he clawed at nothing and felt his body reach the absolute height of ecstasy, the greatest degree of pleasure that he had ever felt in his entire life. Then, suddenly, both of them pulled away and started huffing at him. Jamie collapsed on his back, her heavy breasts making tiny imprints in him "You were great, Brock" she said before lightly nibbling his ear. Mary thought that was pretty funny

"Aww, you girls are cuddling" she said in a mockingly sweet voice, her half hard cock swinging around from her groin as she made her every move. Brock couldn't help but to look up at its motion, feeling himself get hard against the floor and wanting so badly to reach up and touch the thing, but he knew that doing so would be somehow too much. So he just stayed down there on the floor as his bustier sister held onto his torso. Mary smiled at the two and lightly pressed a big toe into her brother's head "Love you, Brock" she said before leaning down and kissing her sister's head "Love you, Jaime" she turned around and made a show of shaking her ass for everyone, as well as allowing her dong to hang loose and demonstrate its complete freedom

"So, what do ya wanna do now?" Jaime asked as she slowly got off of him, awkwardly walking to the cabinet and fumbling around. The question felt very strange on Brock's ears. Why would she ask what he wanted to do? He felt the humiliation of his situation swell over him again, he was raped by his sisters and would probably have to have their children. He had came from his abuse and would probably continue to cum...they were probably going to keep raping him all week, repeatedly making him do whatever they wanted as they just stand there, smugly assured that he had no way of ever defending against them. The worst part of that presumption was the degree to which it was correct, he really didn't have an answer to their brutality, he doubted his parents would even care

"I...I dunno" he said as he pushed himself up, feeling the cum in his mouth and wanting to spit it out. He doubted that would be accepted, so he just closed his eyes and swallowed it, feeling its thickness as it went down. It was barely even a fluid, feeling more like a gelatine as it traveled down his gullet. But he made it go down smoothly enough that he could look to his side and see Jaime approaching with a buttplug in her hand, proudly getting on her knees and shoving it inside of him as he squealed like a little bitch, much to her enjoyment. "I...Oh God I just want to be alone for a while!" he said ass he tried to get up, finding that between the plug and the earlier abuse on his ass, he couldn't really even stand, instead falling back into the arms of Jaime

"Ahh, come on baby bro" the younger sister mocked "I think you'll have a hell of a time hanging out with me, the daddy of that new baby you have inside of you!' she rubbed his belly and began to sensually kiss his neck, before shoving her cock between his thighs. The monster seemed even bigger now, even with a good five inches between his thighs it still stuck out from him much further than his own cocj. His cock that was already getting hard again just by contacting his sister at all. He groaned as she roughly turned him around and looked him over 'Oh wow we really were messy with you, huh?' she said, reaching to grab his buttplug again and make sure it was in there firmly, slapping his little buttcheek afterward in a mocking gesture of good faith "anyway, we at least know my cum is gonna be nice and snug inside of you, filling you up and quickening into a cute lil baby that will be the product of our loooove" she kissed him on the lips. No tongue, just a light and communicative kiss

What love? Did she really think that he loved her? Or did she mean a selfish, one sided love that she was the self declared queen of? Heated the not knowing, he grasped at her thighs and pushed her away, finding that she refused to budge and preferred to pull him further for a more though bout of kissing, digging her tongue into him and moaning against his face before dropping him ass-first into the enormous pile of futa cum on the floor "and clean all that up, will you broke? It's just so nasty and once it gets crusty it is much harder to get off" she giggled at her own language

He looked around his body and then back up at her, feeling himself get steamed as he pushed down on the ground, slightly slipping on the piles of seminal fluid "How am I supposed to clean all of this up!?" he whined. Why should he even have to do it, it was spilled by his sisters when they were fucking him without his consent, what possible responsibility could he have for all of the fluid on the floor? But he couldn't find it in himself to resist his sister. Ot yet at least

She just giggled "With your mouth, silly. I saw how much you loved swallowing everything. So as the baby grows inside of you, make sure it grows big and strong by eating as much cum as you possibly can!"

He looked down at the mess and whimpered, only to get a backhand to the face "Just clean it up. Now!" Jaime demanded,and soon enough he found himself scooping globs of it from the floor and shoving them in his mouth. They were strange tasting, he wasn't sure quite how to describe them but he saw how somebody could get addicted to something like this. He looked back at his sister, who was clapping her hands and encouraging him to keep going and keep eating. He obeyed, walking forward on his hands and knees until he had gotten all the glops that he could get "Can I please stop now?" he asked, finding himself sounding much whinier than he had intended

"Not yet, there's still residue on the floor," she said, squatting down and scooping some up with her finger, rubbing it between her forefinger and thumb "It's all stringy" she giggled before walking up to him and grabbing his head "Lick" she commanded, pressing his head into the floor. He found himself doing as she ordered, all the while she was standing in the corner. She had abreast in one hand and her cock in the other, already hard as a rock again with a member that seemed to be as long as her thigh and nearly as thick as her shin. How had that fit inside of him...no way it had, it would have to have been smaller when she fucked him. But then...did that mean that she was still growing? Why would she be...

"Ahhhh" he moaned, licking some of the last of it off of the hardwood floor before he opened his mouth at her, showing that there was nothing left "I think there's more spit down there than cum now" he said, watching how expertly she was working her own shaft. She was a total champ it in field of self-service, it would seem. He just stood there awkwardly, awaiting instruction as she tied herself up' to her liking

"Uhhhhh, yeah" she moaned, before walking to him, smiling and lightly grabbing his cheek "So, are you excited about that baby inside of you?" she said, slapping his face with her cock hard enough to send his head in the opposite direction before groping the bulge on his belly, feeling the new life being generated inside of him "Ooooh, so warm and cuddly feeling. I bet it's so eager to come out and see the world as soon as its gestated. I am gonna be such a great mom. Or wait, I guess you are gonna be the mom...I mean nothing wrong with having a few different mommies, right?"

He just looked up, cum flowing from his mouth as he considered something to say but nothing came to mind. He just eyeballed her and swallowed what was already inside of his mouth. She placed her head against his bulge. He was pretty sure it was mostly just cum in there right now, right? "You know, it could be cool if you'd asked me if I wanted to have kids before just panting one inside of me" he whimpered, receiving a surprisingly intimate caress as a response, before he got a kiss right on his nose

"Hmm, fair on some level. But unfair to me. I have a right to reproduce, don't I? And you are my brother, so I'd say you have a responsibility to keep the family going. Plus while I may not have asked you if you wanted to fuck, you did cum from the sex, which means you definitely enjoyed it" her words stung, he wanted to get up and call her out on her ignorance but somewhere deep inside of himself he felt that everything she said was completely right. After all, he did seem to enjoy himself despite the immense pain, didn't he? He did cum and probably lick up after himself. And being pregnant was...well it was definitely humiliating but what could he say about it beyond that? It was a somewhat magical feeling somewhere deep in the recesses of his psyche

"Yeah, well, it was still rude" was all he could say. Were her tits bigger now, too? They definitely looked like solid H cups at least, jiggling around just all over the place with every movement she made, no matter how minuscule. He gulped as he considered having to take those titties face to face. He would be the one that they would be making contact with in the future

"Stop being such a whiner unless you are actually looking for a spanking" she said, crossing her arms under her breasts. He was pretty sure he saw them grow a few inches as she did so, but Brock convinced himself it was just an illusion caused by the movement

"I wasn't whining" he said, feeling like a liar as he got up and tried to start walking again, but found that the weight in his belly and the plug in his ass were still making bipedal locomotion rather difficult. Luckily, his sister was there to catch him, slowly leading him to the door to the pool.

"So, before we go out there we should probably wear some suits" Jaime suggested, pushing him onto a couch before disappearing upstairs. He grasped at his belly. The pool may be nice after all of this, feeling weightless would definitely beat the weighty feeling he was getting from carrying around the junk inside of his belly. He tried to convince himself there definitely wasn't a baby, but he just couldn't be certain about that

Jaime came back in a pink bikini, her breasts threatening to break the strings holding the tiny napkins one may call 'cups" in place as her cock made an enormous, ridiculous bulge in the front. That swimsuit clearly was not designed with a futa in mind, especially not one as young, hung, and full of cum as his sister. She saw him ogling her, doing a few poses for him before she placed her foot on his thigh and leaned in, offering him a bright smile before placing the suit in his hands "I think you'd look good in this" she said, and when he looked at what she had just handed him, he was sad to find that it was precisely what he had been expecting, a matching suit, identical to the one that she had on.

"Do I have to" he said as he grabbed the fabric, but the look on her face was all the answer he needed. Yes, he had to and in all likelihood he would have to like it as well. That was just how things were going to be in this house, weren't they? He sighed as he started putting on the bottoms. They fit his own cock quite easily.

He had trouble with the bra, but she was quick to get behind him and tie it for him, giggling the whole time through "You Are such a cute girl! And you know it takes a LOT of bravery to wear a bikini when that heavy with child" she teased, reaching down to grab his bump again before pulling him toward her, her giant cock against his shoulder "You know what, though? I could actually go for a blowjob. You wanna give me a blowjob?"

His mind told him no. he wasn't even sure if he could wrap his jaw around that thing without defining it like a snake. But his cock was telling him yes and the rest of his body couldn't ignore the signals. He whimpered as he got his hands around her waist and sent his heain. He wasn't sure what to do...did she want him to take her bottoms off? She answered by grabbing Brock's head and shoving it against her cock, letting him just feel the meat against himself as she moved it up and down. It was apparent that he had no chance in hell of avoiding this blowjob, she was taking pleasure from him whether he likes it or not

She actually did the honors of peeling her bottoms off of her cock, they looked stretched out when they dropped to her feet, but he was distracted from a further analysis when a cockhead the size of a fist slammed into his face and demanded for him to suck on it. He licked once, tasting the precum and feeling a shiver travel down his spine. He kisses it after that, feeling like it may indeed be a romantic partner.

"Yeah, worship just like that" she cooed, and he went in again, kissing all around the head and licking down the shaft, tasting the hearty salty flavor. He realized he would have to fit it down his throat soon enough, and he looked up at her to beg for her to have mercy and let him stimulate it some other way. Jaime got the basic gist of what he meant, but did not allow him to make any demands. Instead, she grabbed him by the back of the head and shoved him right onto her cock, moaning loudly as she felt herself stretch his mouth out "Just relax, Brock. I know your mouth, you can stretch it a lot further than you think you can

He was slapping her thighs and trying to reason with her as the cock went all the way in, forcing him to open his mouth ever wider to accept her love. It stretched him, or at least he felt like he was having something in his jaw pressed beyond its natural breaking point. But he kept going, some aspect of the cock being so addictive that he had no choice but to chase its deliciousness for as long as he could, attempting to gain whatever was inside of it that may have made it so appealing. He felt light slaps on his face as his neck began to expand to twice its previous size, stretched out by the invading cock

She growled just a bit as she started humping his face, going in and out of the throat he was sure would be ruined by this abuse, moaning as she stood on her tip toes and occasionally bit her bottom lip. He felt precum dripping inside of him by the bucketload as she ravaged him with those strong glutes and mighty thighs. He had no choice but to go all in, licking as well as he could against the terrible onslaught

She bit her lip and took a few moments to appreciate the comfort offered by his throat, feeling something inside of her begin to build up. She was going to cum inside of him, probably a bigger load than both the previous two combined. She ground hard against his ribcage, feeling her cock poke that far, before moaning and letting him know "This is gonna be a big one, swallow everything you can, kay hon?"

He didn't know what she meant by any of that. He was too busy sucking to really understand. But he felt it when she was going to spurt, something about the member inside of his mouth changed and suddenly there was just an enormous torrent of gloppy fluid shooting down his gullet so fast that it physically hurt.

He reached toward her, out of control. His hands were predicted when she grabbed his wrists, making him reach for her breasts. Even as her rockets and rockets of hot, sticky cum assaults his mouth, somehow the boobs in his hands were a total pacifier. He felt calm even as cum violently explodes out of his mouth. It should have made him gag and belch, but instead he only kept on sucking, desperate to get her off in order to impress her.

She looked down and started running her hand through his hair, smiling as she saw how much cum came out of him. She would scoop some off of his chin and neck to feed it back to him, but mostly just let it drip. She figured she may as well simply allow him to enjoy himself for the time being, and soon enough he would grow so addicted to cum that he would lick it up without her asking.

He did look down and see the semen wasted from his blowjob. He strongly considered humiliating himself on his hands and knees, greedily licking it up and filling up his tummy. He looked back up at her and opened his mouth, showing off what a good eater he had been so far...waiting for direction. Did he want her to order him to keep eating? No, that would be disgusting, he grabbed her breasts harder and pulled up, totally unsure of where he was going or why he was going there.

She cradled him "there loverboy, it's all fine," she said as she huffed and cradled him, kicking the door open and waving down at her sister. Mary was in the pool, her strawberry blonde hair sticking to her neck as she swam around in nothing but a speedo. Her cock, too, seemed to have grown considerably, and her once small breasts were at least DDs at this point. He licked his lips, seeing the lust-inspiring image as he crossed his legs awkwardly, unsure of how to approach any of this.

Luckily, Jaime took care of it by bus carrying him down to see Mary, throwing him into the cool water and letting him sink or swim. He panicked briefly before returning to the surface, finding himself much more buoyant in his new pregnant shape. The two women waved at each other and exchanged some pleasantries. Jaime glanced at him before loudly declaring"I gotta go clean up the mess I just made. Half of which is currently running off of Brock and into the pool. Have fun with him while I'm gone!"

Mary swam up and grabbed him around the torso, squeezing just a bit tighter than he would have liked before kissing him on the cheek, enchanting him with her feminine wiles before kissing him on the lips "So, seems like you gave another blowjob? Was it better the second time? I would say you were used to it, but by the growth Jaime's experienced I doubt it was any better than just being a virgin. Am I right or am I right?'

She was definitely right, although he didn't really want to say that. Instead, he just backed up slightly and began to lightly sulk, thinking about what had been taken away from him as he looked back up at his sister "hey, it was pretty fun. She seems to think I'm pregnant though. I'm not sure if I'm ready to bring a baby into this world"

"Oh don't worry" Mary said, her hand reaching to grab the plug under his bottoms "You aren't bringing a baby into this world. You are bringing two babies into this world" she said before reaching around and grabbing hard on his booty. Brock swooned audibly leaning into her and lightly whining as she only brought him in closer, pressing her lips against his neck as she delivered a constant anal stimulation to ensure that he would do exactly as she wanted...get aroused. He reached his hand all over the place, often catching tiny grasps of her as she moved her fingers up and down his body and her lips up and down his neck

He had never been kissed like that before, but she definitely like it. She loved having the soft skin of her brother to make love on, too! Soon enough she had his hard nipples in one hand and was tearing off his swimsuit with the other "I am going to make you such a bitch: she said as she grabbed his shoulders and pushed him under the water.

He wasn't aware that that made swimsuits that would contain such enormous bulges, but as he looked on in slight horror he realized that it wouldn't, for long. Before his very eyes the bulge was growing faster than he knew anything organic to grow! He kicked his legs futilely as he saw the monster grow out of her tiny tiny trunks, now longer than her legs were now staring him directly in the face. Was this the thing that was going to put a second baby inside of him? Why did he feel so...excited about his upcoming abuse. The speedo finally tore off, leaving a confetti for shreds as the cock flew toward his face, making contact and knocking his head around before it was jammed against his face. He realized that he would have no chance of ever getting it inside of his mouth, and began to beat the thighs in front of him in a desperate plea to gain his freedom

"That's the stuff" Mary lightly moaned as her brother struggled underwater, before pulling him up and facing him away from her. Getting behind his back and starting to hot dog his anus. He felt his asscheeks both completely dominated by the massive member that was rubbing between them, feeling more like an enormous leg than any kind of cock. Seriously, why would it even get that big!? "MMM, you seem to like me" Mary observed as she reached forward and grabbed his cock, testing his erection in her hand as the other one went to his anus, grabbing the plug by the base "Do you like the idea of having my adorable little babies? We could watch them grow up together, wouldn't that be sweet? I mean don't you really want to be an awesome mom?"

"NNN-Nooo" he squealed. That squeal ended in some vocalization that was even more embarrassing when the plug inside of him was untimely yanked out of his behind, leaving a brief gape before her hand was shoved inside he grabbed at his own chest, unable to find anything else to comfort him as he was exposed to a totally novel form of humiliation and forced to contemplate the fact that he was aroused by it

Oh yeah, nice and stretched and ready" observed his sister as she slowly started shoving her fist inside of him, feeling him up some as she placed the other hand on his belly "You have grown pretty nicely. And you are going to need to ape just a bit so I can fit my head inside, Okay?' she asked like she was doing him a favor. He didn't respond, bt she had no problem carrying on without him.

The switch came hard and fast, her hand slipped out as her cockhead found its way into his anus, but he realized that he wasn't taking an equal exchange, the penis had grown to a length thicker than her sister's was, thicker than the plug was thicker than he imagined he could take. It was a world of pain just having it in, initially

"Yeah, that's the stuff. Just relax"she would pet his head and occasionally kiss his neck, inserting nothing but letting his asshole grow accustomed to having the enormous insertion inside of it. He would only lightly whine at his predicament, and she would kiss him more and ensure him "This so good. We get to have a nice baby together" she rubbed her hand sensually across his big, distended belly before she finally reached his cock. "You know it's actually pretty funny how small this is. I know you were proud of the length, but it's really barely more than a clit when compared to heat futa have packed down there. You really have no use for one of these at all" she said, before thrusting her hips forward and getting some more cock inside of him.

Getting fucked inside of a pool was an interesting predicament, he was finding that neither of them were anchored anywhere, but his sister was strong enough to pull him onto her cock whenever she so desired. That meant that they would float all around as she controlled their relative locations, and he would just have to lean into the water and gape and gasped as she abused him however she liked. He closed his eyes tightly and found that the pain in his anus was decreasing, that he was somehow sort of starting to enjoy the massive, ruinous insertion inside of him. He even looked back and greeted his sister's smile with one of his own, although in his mind he was just being polite so that she would be less inclined to tear him to shreds

That plan did not work, because she did pull him in further until the thickest part of her cock was at his backdoor, stretching him what felt like several feet as she slowly eased it on through, groaning so loud that he felt like he was going to cum in the water just from hearing her lustful experience. He bent how she wanted him to bend for that section of everything, wanting to please her for reasons even he didn't quite understand.

She pulled him in and made him look to the side so she could kiss him as she slid her penis in all the way to its base for the first time. Hs torso blew up, his clothing probably would have torn from his body had he had any on his belly. She displaced so much when she moved that cock around that he felt like it was the greater part of his being, and she hadn't even started the real fucking yet. She was just kissing him as she soaked and twitched, making him feel like such a dirty slut...

The first backthrust was slow and agonizing. He felt himself stretch more down there in the water before she bit his neck and rammed forward at full speed! He was filled again and screamed out from the sensation, finding his love for her cock growing by the second. "I knew you'd learn to enjoy it!" she encouraged, slipping to half her length again before jamming it right down his asshole, tearing him apart even more as she groaned from her own notable pleasure, getting in closer with him and biting him on the neck and ears as she wobbled herself inside of him and slammed herself as far as she could get, feeling the womb that had been made inside of him and biting his shoulder harder.

He leaned back "Fuck me!" he screamed, shimmying his ass on her cock "Fuck me so hard that I stay pregnant forever. Fuck me all the way through the wall, just jam that cock all the way down my ass and don't let up until I'm more jizz than human!" he realized that he was telling the truth after he said that. She followed his lead, however.

The next series of thrusts was so violent that they were pushed across the length of the pool, Brock soon finding himself pressed up against a concrete wall and moaning like the little bithc he had become with each and every thrust into it, making slight collision after slight collision as his body served as the massive fleshlight for his lustful sister.

She kept going in and out, in and out, making him squeal and cream as he felt her big, fat cock stretch him into a new shape. He squealed and shook, he hollered and hopped, he did everything he could to keep himself pleasured and impaled upon the cock that was giving him so much pleasure that he was nearly bawling his eyes out. Soon enough he felt a wave of hat rise within him and he settled even more deeply onto the cock, reaching back to grab onto something as he breathed in deep and looked forward "fuuuuuuck" he whined in a voice that made his sister even harder than she already was "Mary...I'm gonna cum!"

She grabbed the bulge in his torso and played with it "Fuck yeah you're gonna cum!" she responded, fucking even faster, feeling herself through his gut, and closing her eyes to ensure she got the sensation and the explosion just right. There was a pause before the rumbling. After the rumbling there was a brief respite of rest. Brock realized he was most of the way out of the water, he looked to the house and reached his hand out, wanting the comfort within. But he also wanted his sisters cocks inside of him. Strange.

Mary kissed the back of his head before she grabbed his shoulders and started cumming. If she had not anchored him into her the sheer force of her orgasm likely would have blown him right off of her, but as things were she merely repeatedly beat his ass and prostate with wave after wave of her baby goop, loads spilling out of him even as her cock was still inside, while even more entered his body and started filling him out. He felt his limbs and face grow bigger with his belly, a complete inflation of his body from the juices that were entering it. He knew that he would have something new...that he would be something new before all of this was said and done, and that brought him a great degree of joys.

He was let down outside of the pool, bloated and barely breathing as Mary swam a few more laps in her birthday suit. Before too long Jaime came out of the house to grab him, helping him onto his feet before leading his inflated, lustful body back into the house to get the attention he needed. He enjoyed bathing with Jaime, she even let him suckle from her breasts before she clowned him off and plugged him again, rubbing his belly and sayings he was excited about the upcoming twins.

That night his sisters shared the couch and he saw on their laps. Sometimes he would have one cheek on each sister's thigh, sometimes he would be passed from one to the other. He always felt romanced and loved, however, knowing that his sweet sisters would care for both him and the babies that they had planted in him. He knew he was pregnant, somehow. A feeling in his gut, perhaps? Or maybe just the natural balance of hormones changing so that he would be able to feel that pregnant glow.

He was at a maternity ward the next day. He barely fit into his hospital gown, showing slightly more inflation form the fun his sisters had had with him sitting on their laps, he was euphoric though, serving the two of them was a perfect pastime. He smiled at the two fathers as the doctor walked in. Mary was wearing a pair of jeans and a leather jacket, although the bulge in her crotch area pretty much required those jeans have a third leg in them. It wasn't even a proper "pouch" at this point, it was a hole other leg. Jaime was wearing a sundress and white stockings. Her colossal cock was shoved into the left one, pulling against it so tight, even in its soft form, that you could easily make out the distinct veins going across the length of the cock

The doctor walked in all smiley, placing a hand on Brock's belly before she smiled at him and then looked at his sisters "well, tests are normal. Well normal by the standards of you two scamps" she said, causing both of the girls to giggle and shake their heads. They were quite the virile little duo "the babies are both healthy young ladies, growing at a substantial rate, he should probably give birth inside of the next month"

"Next month?!" he was decently comfortable with his current body, but holding those two babies in for a solid month of hormonal stress and the various agonies of growth just seemed...inconvenient. He grabbed at his belly, the fertility doctor lightly squeezing his finger "O-ok, I think I can live with that," he said before his sisters walked up to him, both kissing one of his cheeks. He sighed and sank into them, feeling them rub their hands across his body and their lips across his face.

"You three really are adorable. I think you'll make a marvelous team of mothers. Now, as for the other news...you should expect a lot more weight gain, and both of your sisters should experience notable growth in-" she looked at her audience and decided to employ her bedside manner "Both of them should become more and more hunga s yoru pregnancy increases, as a sort of sexual defense mechanism. Don't worry, you'll grow to accept whatever sized cocks they want to shove inside of you. And on the bright side, you'll also be stretched enough to easily pass the baby by the time its due" she pointed out, making finger guns and receiving laughs from the two girls while the pregnant boy justs ort of giggled. "Any other questions before I slip into something more comfortable?' she asked as she took her glasses off, biting her lip and undoing a button on her blouse

"Well" said Mary, motioning at her own breasts "can I assume these are also gonna grow as long as I spend time with my new lil baby mama? It's just that they are already H cups and I kind of prefer myself with a more flat-chested look" she said before reaching forward and squeezing her nipples, gasping and lightly moaning "although I could get used to the sensitivity"

"A very good question" the fertility doctor said getting on her knees and unzipping the enormous cock-holster on Mary's jeans "but yes, you can expect growth to increase until the babies are born, some time after that you should return to your previous level of business. I hope that answers your question" she said, before licking across the length of Mary's shaft making her scream in pleasure

"Oh" Jaime said, tearing the medical gown off of her big, big brother "It definitely does' she said before lightly placing his naked torso on the ground and slowly starting to mount him. Her cock was already so huge, but every second she got more aroused, harder, and so much bigger. Her backed up into it as he looked at the doctor's lap, seeing a tent form

"Ahh, maybe you wanna suck something more reasonably sized?" the doctor said as she pulled her skirt up, showing off her nine inch erection. He was embarrassed to even look at it but happy to gobble it up, feeling his sister slowly start to penetrate his hole as he fell once again into the ecstasy of group sex. He felt more fertile than ever.
