Little Miss Massive

[madwolf88]

K+ ! Lovely story! I need some of whatever they are all on!

[quick]

Awesome story.  It'd be great if Dede or another woman came along and actually caught up to or surpassed Jia Na to really motivate her.

[superlurker]

Coming home to find my wife's car missing from the driveway was a rare occurrence. Maggie's SUV and Dede's Benz were sitting on the street as usual, but Jia Na's Civic was nowhere to be seen. I parked my truck and started pulling off my top, waving to Mrs. Schultz across the street as I went inside. Our house was in a beautiful neighborhood, mostly thanks to Jia Na's ability to command a massive salary. My own BAH wasn't bad, but it wasn't going to afford us this kind of house alone. As I wandered into the great room I could see the patio doors were open and splashing sounds were coming from outside. The ladies must be having some pool time. I trudged upstairs to the master, pulled off the rest of my uniform, and grabbed the Speedo my wife had gotten for me, and went about squeezing my oversized nuts into it. I turned around to check my ass out, noticing the suit was functionally a thong now thanks to my oversized equipment. I looked absolutely ridiculous to my mind, but Maggie and Jia Na really appreciated it.  I headed back down and out into the back yard.

Which is when I found out where Jia Na's car was. She had the poor Civic over in the corner of the fenced-in yard and was slowly curling it. I shook my head, realizing there was no way she was going to be able to take a day off when she was on her "Human Iterative Growth Serum" or whatever she was calling it now. It was hard to blame her. She was putting on close to 18 pounds of muscle and a solid two inches to most of her body parts every four weeks. The biceps curling that Civic were closing in on 36" now. She frankly looked ridiculous, bulging obscenely all over with hypertrophied muscles, but also super fucking hot. Her skin stretched so taut you could see all of the striations in her Herculean physique clearly, except for the ones next to her titanic titties, which were trying to break free of her green bikini top. A bit of fur was poking out the sides of her thong bottoms, but she'd gotten pretty OCD about depilation and was having much of her body hair lasered off now.

Maggie was lounging in one of the chaise lounges, her own colossal curves barely contained by a blue bikini that completely failed to conceal the huge red bush growing out of her crotch, the porn goddess having stuck to the request from her tech billionaire "boyfriend" to stay hairy. Even her 25" biceps were covered with a thick pad of red hair now, and as she adjusted her top I could see the hair growing in her own cavernous cleavage. It had taken some getting used to, but she didn't expect me to eat her out, and she kept very clean, so it honestly wasn't all that bad. It looked good against her pale skin and she shampooed all of it, so it smelled fucking great. She noticed me and pulled her bottoms aside to reveal her nearing 3" clit and began twisting and pulling at it, staring at me like a woman who hadn't had a drink in days at a glass of water.

Dede surfaced at the edge of the pool, grabbed the lip, lifted herself halfway out of the water, pulled up her rear, lifted her legs up and over her head, pulling back down into the splits as she rolled forward, and the stood herself up right out of the split. You have to take my word when I say it was one of the single sexiest movements I've ever seen. She swayed her way over to me, pushing herself up against my body and then climbing up to give me a kiss. "Welcome home, papi. We have a guest."

"Oh?" I ask, only then hearing another splash from the pool. I glance over as Dede hangs off me and see a young girl surface in the pool. "That you, Danielle Mastronini?"

"Yes, Mr. Lance! Your girlfriend said it was fine for me to come over and swim. She was going to show me some lifting routines later!" the twelve year old replied. She was a cute kid, bubbly and energetic and very dedicated to gymnastics. But she was just starting to hit puberty and I knew, just glancing at her parents, that there was no way she was long for the sport. Mike Mastronini was a mountain of a man, an all-around great guy who worked in sanitation (yes, really) and threw excellent barbecue parties. His wife Denise was a preposterously zaftig woman, with perhaps the largest butt I've ever seen outside of porn and a pair of watermelons to lug around. Suffice it to say Danielle was going to be big and tall in all likelihood. Really big, if her older sister Michelle was any indication.

"Okay, Danielle. Have fun," I replied. "You want to help me make dinner for these animals, Dede?" I asked the woman hanging off me. She just grinned, grunted in affirmation, and then proceeded to lick my pecs as I carried her into the house. I pulled out the ingredients I'd set aside for dinner this morning and set to work, letting Dede hang off me as long as she wanted to. She licked and sucked and groped to her heart's content. We made -- Dede did eventually climb down to help -- some chicken cacciatore. The rest of the ladies tromped in to eat about 30 minutes later and Danielle apparently had permission to stay for dinner, so I served her up a bowl as well.

"So, you will be here tomorrow. We will lift," Jia Na said to her once the eating was taken care of. We'd all have additional portions later, but everyone had slightly divergent schedules outside of breakfast and dinner.

Danielle nodded. "How long up I can curl my mom's minivan?" she asked.

Dede and Maggie giggled. Jia Na gave the girl an appraising look. "Maybe when you are sixteen," she said simply. Danielle beamed at the answer. She proceeded to entertain us with stories about what school and gymnastics club was like, and everyone seemed to get a kick out of the girl's energy. Eventually, though, she peaked, and I scooped her up and headed over to her parents' place. Mrs. Mastronini opened the door, accepted her daughter, and then openly stared at me. I realized I was still in my Speedo and grinned bashfully.

"Sorry, Mrs. Mastronini. She was in the pool with the ladies until we had dinner -- chicken cacciatore -- and then she talked herself to sleep. I didn't think to change," I explained.

"Oh, don't worry about it. Never hurts to see a beautiful man's body," the older woman said with a grin and a wink. "I'm sorry about leaving her with you."

"She's delightful, really. She wants to lift weights with the ladies, and they're game to teach her. I know she's done some for gymnastics, but..."

"Oh, let the girl have fun. She looks up to your wife. At least for now," Mrs. Mastronini said.

"Sure thing, Mrs. M. Goodnight."

"Goodnight, Mr. Lance. Thank you for looking after Dani."

I waved and departed, certain that the older woman was staring at my ass and really not caring. She wasn't the only woman in the neighborhood staring at my body. Mrs. Schultz waved from where she was...checking her mail? Okay. I waved back, heading into our house with a bit more speed.

"...too young for any steroid..."
"...not a steroid..."
"...unethical..."
"...grow strong..."
I heard the conversation from the kitchen in bits and pieces as I approached. Dede and Jia Na were apparently discussing what sort of drugs would be appropriate for Danielle. I shook my head. That girl was going to be a monster for sure with the two of them involved. The two paused as I walked in, both openly staring at my crotch.

"Post-dinner fuckathon?" I asked. Both of the women grinned and nodded.

"Okay, see you ladies on the patio."

[mattrius]

I'm really getting into this story. Curious to see what happens next! Hope the writing is going well.

[superlurker]

When Dede had finally given the all-clear on everyone else using Jia Na's new drug, which she dubbed Megabulge, she was tipping the scales at 502 lb and teetering under her own weight. It promoted testosterone and estrogen production and as a result, caused primary sexual characteristic growth as well as muscle gain (a secondary sexual characteristic). Her libido stabilized somewhere around "desires sex constantly, needs sex a few times a day," which fortunately coincided with the end of my term of service in the Air Force. There'd been a lot of suspicion around my massive gains anyway, and simply departing meant that nobody needed to worry about it.

A bare couple months on Megabulge had seen me push up to 430 lbs and carrying around a couple of cantaloupes in my pants, as well as a kielbasa. Junior enlisted apparently had found out where I lived and there was a constant stream of young women knocking on the door looking for the ride of their life. I indulged some of them, but mostly Dede and Maggie turned them away. One of the more interesting ones had huge bolt-on tits and wanted to be choked by my massive arms. She was in great shape, and actually decent at wrestling, so holding her down to choke was tough. The rest were just typical young women looking for a trophy fuck, and I was happy to oblige.

I spent a lot of my time oiling down the huge and growing bodies of my ladies, slathering them with a variety of cremes and ointments to suppress stretch marks as they built their physiques far past the usual pinnacle of physique. That's how I found myself rubbing creams and lotions into Jia Na's muscles while she sat astride me, monitoring her young protegee, Danielle. Jia Na's gigantic glutes were sitting right on my abs, and I was currently running my hands all over them to get them good and creamy. She'd occasionally flex her butt, making it snap around in shape and throw my hands off. She was doing it deliberately to amuse herself, as most of her attention was on correct Danielle's form and pace.

I moved on to Jia Na's waist. 42 inches of the world's greatest core was on display, and all of it needed to be treated. I ran my hands across her obliques and onto her Adonis belt, gripping the huge muscular strands and squeezing a bit before returning for more cream. If Jia Na noticed the pressure, she didn't indicate it. My hands returned to the front of my wife's abdomen and I began to fondle her pool-ball sized abdominal muscles. Slipping my fingers in and really working around them, each crevasse an inch deep and in need of cream and massage. By the time I got to the third row her big breasts were beginning to inhibit my ability to reach her abs, and I indicated it to her. She lifted the 70 pounds of tit up like it was nothing and I went back to work, knowing my wife -- and probably Danielle -- could see my growing erection. I moved my attention to Jia Na's lower back, climbing down the ladder of her spine with my hands and working my way through each of the hyper-striated muscles. I heard my compression shorts creak as they strained to contain my cock.

Danielle walked over and racked the 150 pound dumbbells she'd been working with and took a moment to work her leotard back into place. Despite being in the early stages of puberty, she was sporting 19" biceps that stretched the fabric in the arms of her leotard to near transparency. Her huge delts, traps, and pecs were straining the neckline of it, causing it to creak every time she inhaled. Her cobblestone abs showed clearly through it, and it was fortunate that her enormous glutes and quads didn't need to fit inside any fabric, as the 4'3" pre-teen's legs were otherworldly constructs at this point. Jia Na had kept her on a relatively low dose of Megabulge her prepubescent body had really responded to it. She bent over to grab her leggings, step into them, and pull them up, leaving the waistband flopping around her wasp-on-steroids waist. "I'm going to go for a run. Just 20 miles, so about an hour," Danielle said as she turned around and came over to give Jia Na a hug and me a smooch on the forehead. "Then you can cream me," she said with a giggle. And that was enough. My cock surged through my overmatched compression shorts and my cockhead slapped into the valley of Jia Na's breasts.

The muscle girl turned and headed for the stairs, not quite flouncing, but clearly showing the effects of lessons from Michelle on how to make men look. As she did, I picked Jia Na up by her waist and she obligingly pulled her athletic thong to the side to give me clear access to her drooling pussy. Apparently Danielle's flirtation had done it for her, too. I slid into her steaming cunt and felt her kegel-trained muscles clench on to my cock. Then she proceeded to do a full workout routine with my cock inside, my huge nuts churning to keep up with the demand for jizz to bathe her womb with. Jia Na grunted and groaned her approval, pulling her sports bra assembly free at some point before spinning herself around on my rod in order to bury me in Chinese mountains. I kept getting milked while I was slapped in the face with 70 pounds of tit repeatedly, my wife convulsing through a series of orgasms as I ran my hands greedily over her god-like body. About fifty minutes later Jia Na dismounted and went over to the cubby, pulling out a new set of compression shorts for me and throwing them, and a towel, at me. We'd both just barely finished getting decent when Danielle returned, flushed but not winded, and peeled her leggings off and reclaimed the 150s.

"Can't wait until you fuck that look on my face," she said to me, glancing at Jia Na. "That 'I was just fucked by a god' glassy stare." She started cranking alternating curls with the dumbbells.

"You too young for that," Jia Na said simply, moving over to correct Danielle's form. "Need bigger muscles first." She winked at Danielle in the mirror.

"But, maybe time for us to have kids." She said, looking at me now. "Dede removed IUD. Maybe I stop pill."

I knew Dede had gotten her IUD out. She had made her intention to get pregnant clear through her constant desire for cum baths. In theory Megabulge alone wouldn't inhibit conception as it didn't prevent periods like a serious cycle did. Both Dede and Maggie were making supernatural gains on Megabulge anyway, and it wasn't clear the steroid cycles were necessary. My Latina lover was closing in on 450 pounds of rock hard mega muscle, and Danielle had jokingly declared her gargantuan ass "the model." Personally, what turned me on most about Dede these days was that her pecs, traps, delts, and lats were teaming up to completely surround her head. She had trouble looking left and right now, and while up was still okay, down was becoming harder every day.

I started to head up the stairs, although I did hear Danielle asking a question.

"Auntie Jia, what kind of wax do you get? Should I get a Brazilian?"

I shook my head as I entered the kitchen. Stepping in from the pool deck was Michelle, Danielle's older sister, who was back on summer break. She was a competitive cheerleader at her college, and her slim, tight body attested to that in her stringer. "Oh, hi Mr. Lance," she said with a wave. "I was hoping you had time for some...um...jousting."

Real subtle. I'd fucked Michelle at her request a couple times before. Right after her senior prom. Before she left for school. Not that she had any shortage of potential studs. With her K-cup tits and incredibly hard body there wasn't a straight man anywhere who wouldn't fuck her upon request. But she was a size queen. Cock, muscle, and height all mattered to her. I knew because she kept sending me pictures of other guy's dicks in her. Visiting Defensive Ends, Linebackers, and Linemen were all victims of her insatiable need for big. Their teams suffered for it, too, as they were usually too drained to play their best.

"Fuck it, sure. I'll fuck you on the pool deck so your mom can watch," I told her, grabbing her by the waist and pulling her up against me in a baby carry.

[superlurker]

Once we were out on the patio I grabbed Michelle by her waist with one hand, lifted her up, pulled down my shorts, pulled her bikini bottom to the side, and slammed myself home into her quivering cunt. Glans to cervix on the first stroke, she was dripping wet and fully lubricated as I'd expected. I settled her on my balls for a moment as I removed her bikini top entirely and tweaked her nipples before waving to Mrs. Mastronini who was settled in watching us from the second floor of her house, one hand buried in her snatch and the other returning my wave. I gave her a double bicep pose before I returned my attention to her daughter.

I grabbed her by her waist with both hands and used her as an onahole. Michelle's pert, tight ass and rippling four-pack warped around my cock as I manhandled her to multiple orgasms. Up and down, up and down, twist a little, bounce her on the glans, spin her around and bury my face in her massive K-cups, up and down, give her a kiss, and on as she moaned and vibrated on my dick like an expensive sex toy. Michelle was easy. Being manhandled was part of it, my overall huge frame did a lot of the work, and the little bit of affection shown all worked to get her cumming almost nonstop. When I finally had to jizz I just held her down and let the volume of the jizz force me out of her, sending her into further orgasmic paroxysms. I grabbed her and put her down on one of the chaises, and then directed the next four loads onto her, drenching her completely in jizz.

A pair of gargantuan arms wrapped around my midsection just then, and a well-manicured hand snagged my rod. The 50 inch biceps slapped into my body as the woman behind me jerked my cock several times to make sure I was done unloading before she shimmied around, slurped my dick into her mouth, and went to town sucking me off. My pole was spotless save for a few dabs of her spittle when Dede finished, and I'd enjoyed the massage from her DSLs as she worked. Then she turned her attention to Michelle, scooping up handfuls of cum and filling her mouth to overflowing. "Mmm, protein," she murmured between mouthfuls, working diligently at unbathing the teenage cheerleader.

Dede was bloated with muscle, her previous borderline unsafe cycle combining with the Megabulge to give the dear doctor her 50 inch biceps, a pair of pecs that looked like someone had strapped satellite dishes to her chest, a wasp-ish 34 inch waist, and her supercharged, absolutely enormous legs and ass, with almost 80 inches of butt on display and over 80 inches of quad. Settled into a squat like she was now, it was enough to get me instantly erect. I slapped her ass, pulled aside her panties, and thrust into my Latina lover. Slow strokes as I warmed her up, then quick strokes to get her panting, then slow strokes again as she ate my cum out of Michelle's pussy like she hadn't just licked close to a gallon of it off the cheerleader's body.

I grabbed on to Dede's huge ass and started to slap my giant balls against her solid 3" of clitty, enjoying her screams of pleasure, before releasing and reaching up to grab her ponytail from where it was resting between her hypertrophied traps. Yanking back on her hair I felt her cunny contract around my cock, and got off on watching her try, and fail, to turn her head back to look at me. Her monstrous traps and deltoids prevented her head from its full range of motion, and I knew as her pecs got more pumped up she'd lose even more mobility. Frankly, watching Dede waddle on her preposterously oversized legs was always a huge turn-on. As she knelt obediently, with my hand on her ponytail, my balls slapping her clit, writhing in pleasure I was satisfied, and dumped another huge load in her womb. Then I pulled my dick out and re-glazed Dede and Michelle before grabbing my cock, looking Mrs. M right in the eyes, and jerking myself to another couple of ejaculations which I dumped on her daughter and my doctor.

I leaned down next to Dede's ear and said "Get pregnant," and watched her writhe through a whole new series of orgasms. She was not a complicated woman.

[superlurker]

I let Dede lead by about twenty feet on the way through the CostCo parking lot and enjoyed the double-takes, look-backs, and straight staring she was garnering as she waddled along in a pair of completely outclassed white yoga pants that clearly showed her red thong from basically every angle, side strings over the top, in her expensive trainers. Her ass plummeted as her hamstrings asserted themselves with every forward stride, her quads bulging, the yoga pants creaking ominously. Her armored midriff was completely bare, her long-sleeved half shirt snug to the bottom of her huge pecs. They rose and fell with every stride, too, but that was a more conscious decision by Dede, who wanted to replace the bounce of breasts with her ponderous pecs.

Some people looked at me, too. I was a big guy after all, and even loose basketball shorts couldn't entirely downplay my massive equipment. Danielle drew some looks too, hanging on to my arm, her own massive-for-her-size-and-age arms attracting notice as well. She was wear her typical attire: an overmatched leotard and compression pants duo that only highlighted her extreme frame. I scooped the incredibly muscular pre-teen up and settled her on my back with one of my arms supporting her seat as we reached the entrance, catching up to Dede as she grabbed a cart.

"All the men were staring at your butt, Miss Dede," she stage-whispered conspiratorially with my live-in Latina lover.

"As the boys will at yours, nina," Dede replied, winking at the girl. "Now, we have five superhumans to feed. Help me!"

We walked through CostCo with our two carts, the two women pointing and arguing and putting things in carts. I mostly watched the other shoppers. Both girls drew stares and double-takes. One old lady asked Dede if she could feel her pecs, and Dede agreed, which lead to a weird moment where a lot of shoppers watched an old woman grope my girlfriend. Dede slipped her a card and told her to call. Probably wanted to see how an older woman's physique would react to Megabulge. Danielle's 300 pounds of mass proved that pre-teens responded just fine. I knew Dede had found a young boy for the study too, and had reported he'd just hit 200 pounds himself. So he'd probably be a giant by the time he hit puberty. I felt sorry for the kid's future lovers, honestly.

Dede stopped below a huge stack of water and frowned. "The water we need it up there, and on the pallet," she grumbled before settling her things on her cart, walking over, and simply lifting the 4,400 pounds of water off the shelf. Her body bulged to meet the demands and I felt Danielle shift on my back and sigh.

"I want to be able to do that," she breathed as Dede shifted one pallet to her other arm and then repped the 2,200 pound pallets a few dozen times. Dede chucked when her top's seams snapped, settling the pallets on the ground and retrieving the water bottles she wanted before re-stacking the pallets and replacing them to the shelf.

"You curled 250 pounds with each arm last night, nina. You're getting there," she assured Danielle before bending over to stick the water bottles on the bottom shelf of the cart, making sure we both got a good look at her inhumanly large, firm, jiggly, and striated ass through her stressed yoga pants. I heard groans from behind me and assumed a lot of pants had just been ruined.

Dede led us off to the checkout, and then refused the cart and chose instead to just carry everything with one hand. I loaded the groceries into the Suburban for her while Danielle used the liftgate to squeeze in a few dozen pull-ups. We headed back to the house to cook the 35 more meals we'd need to make it through today. Danielle had some sort of protein smoothie in her hands as we pulled out of the CostCo parking lot, greedily sucking down the calories and protein that would drive her next workout. Dede, on the other hand, hungrily eyed my cock.

[superlurker]

Jia Na was pressing out another squat repetition as she lifted me off the ground in addition to the massive water tank that was sitting across her shoulders. With the water currently in it...it was probably in the neighborhood of 4800 pounds. She paused at the top of her rep, let my diamond rod slide out of her cunt until a couple inches were left, then used her super kegels to pull me all the way back in before squatting down again. I ran my hands over her inhumanly large, striated, but still soft glutes, down her titanic thighs, and then back up onto her awesome abs. My wife was the ultimate sex machine now. She'd put on 100 pounds this summer, just shy of 600 pounds now, and could rip cum out of me with any of her holes with staggering ease. She'd removed her athletic thong but was still wearing the absurdist sports bra array she had custom made.

Maggie was nearby cranking out reps with 750 pound dumbbells. The massive redhead had continued to cycle clen, tren, dbol, and several other serious anabolics. It was showing. In addition to being 700 pounds of she beef, she had a downy coat of ginger fur peeking out around her outmatched white thong and from within her otherwise bare breasts. Her huge pecs surged with every rep, smacking her in her extraordinarily wide jaw. The massive dumbbells were pumping her 66" arms up so much that they were displacing her enormous breasts. She was something else. Dede was shoveling nutrient mush into her mouth every couple of reps, and as soon as Maggie ended her six hour workout, she'd be hooked up to a saline IV. She was licking her lips as she shifted the massive weights like they were nothing.

Mrs. Mastronini was over near the bench giving Danielle the same treatment. Our little Olympian had hit puberty and begun to put on size and weight at a prodigious rate, and was basically constantly eating and hooked up to rehydration IVs these days. She'd started the summer at 4'3" and 185 pounds and was currently 5'8" and 496 pounds of shredded she-beef. She was repping 2095 endlessly, apparently trying to hit exhaustion. She showed no signs of slowing down, either. Dede speculated that the extreme hormone load from Megabulge had pushed her body in a double puberty. Her gargantuan pecs bulged every time she pressed up, threatening to end her poor leotard's existence.

Dede was 675 pounds of rippling she-beef. She was wearing a leotard and nothing else, her world-destroying ass no longer capable of staying contained in even the stretchiest pants for more than a few hours. She ruined a set of scrubs every day in the OR. Her pecs, traps, lats, back, and delts combined to make her head nearly impossible to see now. She turned and saw me looking, so she casually flexed out of her shirt. Just popped most muscular and split it along its seams. Removed the shredded remains and flexed her abs at me, creating a rippling field of hyper-shredded, hyper-vascular girl abs. One where I could not see her face over her colossal pecs. I busted my coconuts inside Jia Na almost immediately. Dede's cunt quickly soaked through her overmatched athletic thong as she watched me push half a gallon of jizz into the Chinese superwoman who was, by the way, still repping out squats

The Mastronini matriarch was wearing a pair of athletic pants and a t-shirt over her sports bra, but she'd been geared up for a couple months now and the results were showing. She'd gone from pretty MILF to S-tier trophy wife, and Mike always looked worn out these days. She smiled at me as she saw me glance her way, but quickly went back to feeding her baby girl.

Then, the doorbell. Having just nutted I slapped Jia Na on the thigh and she dropped me. I pulled myself up, slipped into my custom made compression shorts, and went ton answer the door while toweling off my own sweat.

I pulled the door open after the second ring on the doorbell and saw a smallish woman standing there. Small by my standards, pretty large by normal standards. I recognized her, too, as one of the senior officers I'd worked for.

"Major Riviera, what can I do for you?" I asked as she straight up stared at my naked body and my huge junk in the tight shorts.

"Oh, ah, Captain Lance. Um. Mr. Lance." She glanced up at my face. "Is it alright if I come in?"

"Sure," I said, gesturing for her to enter and closing the door behind her. I took her jacket, leaving her standing in tight yoga pants that said "Air Force" across her ass and an underarmour tank that left her ripped arms and delts exposed. "I hope this isn't about the service. I'm done with that. One look at me and the docs wouldn't know what to do," I said, chuckling. I was well over 600 pounds of rippling muscle now.

"I need a man to get me pregnant. A big man, with strong genes..." she started rambling, breaking into Spanish at some points. I stopped her with a raised hand.

"Aren't you gay, Major?"

She blinked at me. "Um...bi, but married to a woman, yes."

"So what's this about?"

"My parents are demanding grandkids and, um, IVF and sperm banks are expensive. So...uh...I was hoping you'd be up for it? Old fashioned?" She said, looking really awkward.

"Why me?"

She snorted at me. "If you bottled your sperm women would literally kill for it. MIT engineering grad, tall, good teeth, built like a god, Dios Mio your cock is enormous..." she trailed off. "Daphne also says she's only okay with this if the man is clearly better than her."

I laughed. I'd met her spouse once. She was a personal trainer as I recalled, 6'2", blonde, huge and ripped. Tall order for poor Major Riviera.

"Well, you'll need to talk to Jia Na. My wife. And Dede, my doctor," I said, taking her seriously. "But honestly...chemistry matters. You're a little small for me."

"Then put me on the stuff," she replied, equally serious.

[Wookey]

K+ another great chapter

[Ddraig]

I really wish see how big they got

[superlurker]

"Okay, we put you on stuff," Jia Na said, waddling into the room without her bottoms and leaking jizz steadily from her cunt, which was trying to suck it all back in.  "Then we all get pregnant together. Kids can be raised together."

Dede gyrated her way into the room, her massive bulk barely clearing the entrance. "We'll double dose her. See how much the process can be accelerated." She reached a hand out to shake. "Doctor Denise Lance-de la Cruz, but everyone calls me Dede."

"Carla. Carla Riviera," Major Riviera replied, taking Dede's hand cautiously and shaking. "You're both incredible. I mean, I'd heard, but still. In person and mostly naked...my girlboner is rock solid right now."

"Good. You will need girlboner for Friday orgys. Bring spouse next time," Jia Na said, having decided she'd seen enough and turning to exit.

Dede gave the other woman another looking over, then turned around and wobbled out as well. She came back in a couple of minutes where I'd caught up with Carla and handed her a bottle of Megabulge. "Normally once a day with meal, but you're doing twice a day. I recommend your femoral artery near your vagina to minimize people's opportunity to notice, but I'll be sending over a prescription for this to your physician in the morning anyway." She pulled a bag around and handed it to the smaller woman. "Syringe pack, since you probably don't have any yet."

Then Dede bent over and slapped her glutes together in my face, spraying me with her lubrication. I was instantly hard and Dede deftly fished my cock out of my shorts and stroked it in front of Carla. "Remember, this is your prize. Whatever doubts and fears you've got, this is the endgame. This monster cock."

Carla visibly gulped as Dede worked my shaft.

"Come here. Put your mouth on the glans. Ultra high quality protein to help get you started," Dede said, looking the smaller woman in the eyes. Carla relented, did as my doctor ordered. I blasted a half gallon of cum into Carla, and she struggled but managed to keep it all down. Dede leaned in and gave her a kiss on the mouth. "Good girl. Go. When the feeble weights at your gym become too light, come back here and lift with us."

4 Months Later
Carla groaned as she settled on to my dick, her now 365 pound frame bulging obscenely with thick brown muscle. Nearby the rest of the women kept pushing massive weights. Jia Na had gotten osmium free weights and plates made and those had replaced most of the original gym equipment. Carla had just pushed out 1200 on bench and she'd claimed another "practice round" on my dick for her PR reward. I didn't mind any more, she'd pushed past feminine norms and was a bulging ball of beef now. She'd long since surpassed her wife and would send videos of herself at her wife's gym casually curling what the clients were squatting.

She looked down at me with her sea blue eyes and beamed. I gave her a smile as she started to buck on my cock, but my attention was on what Jia Na had said earlier today. She'd figured out the genetic engineering problem she'd been stuck on for bigger gains. She'd showed me a picture of "Subject 12," a young woman who'd started out very normal and through the gene treatment had acquired breasts nearly the same size as her whole previous body, and a body that would shame male bodybuilders. She wasn't taller, but the other impacts of the genetic engineering were striking. Large horns protruded from her forehead, and a tail sprang from just above her colossal ass. She was a cow chimera, a mix of various animal traits that expressed in primary and secondary sexual trait growth, not dissimilar to the super hormones of Megabulge. But the expression also required accepting additional traits of one of the animals. This subject had chosen cows. Jia Na had selected Belgian Blues. This girl was literal lean beef.

"I want to fuck her," had been my response to Jia Na. She said she'd think about it, but was polling the ladies on what they wanted as their chimeric primary. She told me I didn't have a choice in her matter-of-fact way. "You horse. Stamina and big cock most important."

I couldn't wait to see what all the girls looked like chimerically enhanced. It also put a timeline on pregnancy. The process would take six months. Then all the women would take on children.

I glanced up and noticed Danielle staring at me. She'd sprung up to 6'3" and was teetering at 900 pounds. The blonde woman -- and she was definitely a woman now -- bulged obscenely with mind-blowingly huge muscles as she accepted another spoonful of supplemental protein into her mouth. Supplemental protein that I knew included my jizz, because Jia Na had made it a part of the program. A hydration IV sat in one of her 82" biceps, ensuring the growing girl got enough water. Her custom made hot-pink leotard clung bravely to her gargantuan frame, doing nothing to hire the huge blonde bush Danielle was proud of growing. Proof of her womanhood to her mind, I supposed. She licked her lips as she continued to Arnold curl 2500 pound dumbbells. She turned 13 tomorrow.

Six Months Later
I flexed my gargantuan double biceps, each over 90 inches now, while the women continued to stuff their mouths with boiled chicken and sprouts and their eyes with me. Eight ravenous pairs of eyes running over my exposed body, eight juice-jacked jaws chomping down tens of thousands of calories, sixteen massive arms shoveling more food towards their mouths. My hands dropped down to my basketball-sized nuts and nineteen inch pussy pounder. The results of Jia Na's breakthrough genetic engineering technique, I was a massive super stud and as I began to spray the eight women still trying to gulp down pounds of chicken with my firehose ejaculation I felt like a god.

Huge gobs of sperm landing on their faces, in their mouths, on their pecs, in their hair, on their tits. Six full gallons of superhuman jizz, packed with some of most potent protein on the planet. They were all bathed in it. I felt my tail flick involuntarily as I kept splattering spunk on the women and their dinners, which they hadn't abated in eating.

Leandra broke first. The monstrously huge black woman was Jia Na's work colleague. She'd figured out what Jia Na was working on and demanded to be part of it, and when she realized Jia Na intended to use it on our erstwhile family, she simply joined it. 5'11" and originally possessing a thin model-basketball player type of body, Leandra was without a doubt one of the darkest-skinned and most beautiful women to ever ride my cock. Her already sharply-defined features became even more brutally defined by the hormone overdose and the chimerism. All of the women had cycled anabolics during the six month interlude, hoping that coming off a serious cycle would kick their fertility up a notch, and Leandra's body had become comically chiseled. She sported a twelve-pack, although with the way she was sucking on my dick right now, she'd have a pooch in a few minutes. Those huge, cushiony DSLs generating insane vacuum with Leandra's mighty lungs behind them. Her big, brown eyes staring lustfully up at me despite the fact her head was completely immobilized by her traps which rose seven inches above her head now. So monstrous were her pecs that my cock was getting paizuri from them as she sucked on my dick. Leandra instinctively flexed her 96" arms, trying to draw attention to her fertility. The downy ears on top of her head twitched and her fluffy tail was going wild as she started to orgasm once my cum was rocketing down her gullet. Her cheeks puffed up as she deftly contained all the precious protein. I had no idea why the biogeneticist had chosen squirrel as her primary chimeric animal, but there was no denying she was smoking hot.

My new stud's constitution came with the horse cock stuck in her mouth, and the tail that, honestly, I'd gotten used to. I'd added hundreds of pounds of muscle, and a lot of it to my ass and thighs, which meant that my strokes could shatter concrete. The women loved my physique because it made me better able to jackhammer their cunts, and they were all muscle lusting weirdos anyway.

The other women had run out of chicken and were busily, greedily licking jizz off themselves and each other. A few minutes later Jia Na called for quiet.

The room was quiet except for the boiling churn of my nuts as they readied me to stud again soon.

"Now. We draw lots. You know order. Ian blasting all wombs tonight. Make sure you have IVs." She said, sounding calm. But I could see her colossal tits bouncing as her pecs betrayed her anticipation. Her skinny tail wasn't doing much better at hiding it, lashing around with glee. Her cute ears were swiveled on top of her head, facing me and the churning gonads that would later fill her to her maximum.

The blonde giant at the table frowned. "Except me."

"Yes, except you Danielle. You thirteen."

"Yeah, thirteen," she said, standing up and flexing a bicep that was well over 120 inches around. She wore a straining bandeau and a pair of boyshorts that was overflowing in nearly every direction with her pale blonde pubes. She was over 7 and a half feet tall and weighed more than any two of the other women combined. She was a titan. One who was going to stop taking no for an answer soon. Her bandeau strained audibly trying to contain a pair of breasts that would supply an entire school of pubescent girls normally. Her golden, furry ears swiveled towards me. She addressed me, her bushy gold tail wagging. "Well, Mr. Lance? Don't you think age is just a lesser number? Don't you want to breed me?"

I looked her in the eye and shook my head. "You're not mature enough to handle this yet, Danielle. If you just want to get fucked, we can put Mrs. Robertson's son on the treatments. He stares at you constantly, you know."

Danielle frowned. "The trophy wife? You mean Cole? Kid's a total dork, gross," she blanched.

"My point," I replied, still holding on to my huge cock. "You're a good girl, but still a girl." I reach up and gave the massive golden retriever chimera a pat on the head. Her tail involuntarily wagged, but she looked upset. Her mother came up and patted her on the arm. Her 2800 pound frame shivered as the mama bear gave her some attention.

I turned and followed Jia Na's mousy tail and Dede's foxy ass into the den, which had been turned into a literal breeding den full of padding, bedding, pillows, and the like. Waiting in the middle was Maggie's ginger furred form, replete with a cute ginger bunny tail rising from her rock hard ass.

Carla's big bovine butt and her wife Samantha's tiger tail followed us in.

I knelt behind Maggie and slowly slid my horse cock into her tight, trembling pussy. And then my massive ass and thighs went to work jackhammering my long time girlfriend and soon-to-be baby momma. My massive equipment was rapidly slamming into Maggie's butt with enough force to drive a nail into concrete faster than the eye could follow. It sounded like a machine gun going off as my huge, heavy balls punished her five inch clit. This was all business. I was in stud mode. This was strictly for knocking a mare up. I wasn't concerned for her pleasure in this moment, and Maggie was bucking like crazy on my ram rod.

I flipped her over so I could see my massive member blast through her ten pack abs. Her 100" arms struggled to contain her monstrous mammaries, and they threatened to flop into my face repeatedly as I practically tore her cunt open with my colossal cock. I started cumming and her stomach started to inflate. It grew rapidly in size as I unloaded gallons of jizz into her womb, until finally the overpressure threw me out of her. The women fell upon the spilling sperm like ravenous animals, and I sat back to enjoy my three minute refractory period. I had six more women to go, and then another few times through the rotation.

[superlurker]

With Maggie lying contentedly with cum slowly oozing out of her pussy, I turned my attention to the next woman, Mrs. M.

I disconnected the trophy wife from her teenage daughter and pulled her down to sit on my shoulders as I lay down. I tore her yoga pants off and then ripped her lacy thong to shreds before grabbing her thick thighs and pulling her onto my face cunt first. I rubbed her cute one inch clit with my nose as I stabbed my tongue between her inner labia, enjoying a blast of MILF juice before I began lapping away at her inner walls.

Estelle -- she insisted I call her that -- had transformed herself from an exceptional MILF trophy wife to the finest trophy wife in the world, MILF or otherwise. The 54" thighs I was between supported an ass that at once declared her motherhood and her goddesshood. Thick, round, juicy, and still slightly dropped from childbirth and wobbling with a bit of fat, it was top five in the world, easily. Her shredded eight pack was unreal, even beneath the stretch marks that informed you she was an experienced mother. Creeping veins and a jizz-worthy Adonis belt helped frame them on the bottom, and huge lats and a pair of watermelons sitting on four inches of pec plate composed the top. I hung on as she rocked on top of me, pulling her arms up into an enthusiastic double bicep. Her 33" biceps were modest by the group's standards, but easily placed her in a class of her own as far as muscle MILFs go. Her blonde hair was pulled up into a bun that did nothing to reduce the brilliance with which it shone, and her pale blue eyes were fixed on me, revealing themselves every time her massive breasts swayed out of the way. She'd had a pretty face before and the Megabulge had only more clearly defined her fantastic bone structure.

I started sucking on her clit, and varying my licks as she started her cute little mommy moans. Her airy soprano rang out in pleasure just as she crashed into orgasm, drenching me in muscle mommy muff milk. I drank my fill before standing up and allowing her to slide down my cobblestone abs on her way to pussy penetration. The mega MILF beamed at me as she sank onto my cock, and I started to work her cunt while remaining standing, using gravity to assist my massive rod in finding her cervix. She quickly plowed through to another orgasm, her gasping and moaning ringing through the room even as the other women watched. I walked her, still bouncing, over to Danielle and pressed her up against her daughter. Using the gigantic teenager for leverage, I leaned in and stuck my tongue down Estelle's throat, but as I did, I looked up at Danielle and gave her a wink. The teenager looked a little angry at being treated as a toy in her mother's impregnation, but she got into it soon thereafter, running her hands over her mom's colossal titties, encased though they were in a sports bra. She settled her own huge mammaries on the broad shoulders her mother sported, trying to lean down for a better view of what I was doing to Estelle.

Estelle reached up for her daughter's immense 120" arms, grasping at the striations as she hit another level of arousal and crashed into a short series of orgasms as my massive balls slapped into her ass and her daughter's legs. As Estelle's kegels rippled around me I finally reached my own orgasm and blasted the trophy wife full of jizz. A dozen huge blasts right into her womb, her body being held on my cock by her daughter's immense tits. Estelle understandably went nuts, slipping into a long series of orgasms that continued even after I'd pulled her off and settled her onto a large pillow. The other ladies dove in, covering her body with their tongues as I sat back. Danielle, though, stared at me before mumbling "excuse me" and dashing out, one hand reaching for each side of her leotard.

I had a second round of cum and turned my cock towards the mess of women and let them have it, splattering my jizz all over the seven sexy ladies as I finally entered my refractory period. Dede wriggled over and lay on my abs, having trouble waiting for her turn.

[monstarmaster]

Great story so far! Will there be another chapter soon?

[superlurker]

As my cock rose back to service, I picked Dede up and put her in between Carla and Sam. I bent all three women over and after I set my cockhead in the inner labia of Latina wife, I reached over to the other two women's pussies and started working their labial folds as I steadied my rhythm inside Dede.

Slamming my huge baby batter building balls right into Dede's humongous hamstrings and cute semi-clit at a pace that would be impossible if Dede's own not inconsiderable strength wasn't dedicated to reciprocal motion, I surveyed my territory. On the left, Sam's colossal tiger-striped breasts swayed wildly as she bucked and squirmed against my fingers, her more modest ass looking almost small underneath her lashing tail next to Dede's turbo diesel dump truck with her sexy puffy fox tail swishing around. The Scandinvian blonde's physique had gone from professional female bodybuilder to something beyond superheroic. She was intensely proud of her almost 60 inch arms and never seemed to get enough of emasculating the dude-bros at her gym. As I felt myself building to a climax, I pulled out of Dede and slammed my cock deep into Sam's pussy, smashing past her cervix, feeling my colossal balls slam into her hams and glutes and then I released. A gallon of cum slammed into Sam's womb and she screamed and gushed girlcum all over my dick. As she collapsed I pulled my dick free and slammed it into Dede's waiting mouth. Her big, thick DSLs went to work keeping my erection up while my balls boiled away making more cum.

My right hand slipped back into Carla's waiting cunt, working the other Latina's clit and making her squirt several times as my Doctor ministered to my erection. Carla's own body had gone from modest fitness to world-beating hypertrophy wife with massive fucking milk-bearing titties. Her glorious, hyperripe ass, cobblestone twelve-pack, and counterbalancing pec-tits gave her a look like a sculpted sex toy. Unreal strength surged between my hands as I grabbed her obliques and lined up my reinvigorated cum cannon. Her back and lats rippled and flexed as she felt me penetrate and then she turned into an orgasming bowl of jello around my horsecock, her tail switching wildly as I thrust. Every thump of my scrotum on her hams sent her into another paroxysm of squirming, making her pelvic floor muscles try to milk my dick. It was an amazing sensation and I reveled in it as Dede began rippling her insane abs in front of Carla. Inspiring me to thrust harder, faster, and deeper into the other Latina wrapped around my dick. A massive ball of cum flew into Carla's womb as I started cumming, filling her completely with enough to spare to paint her bath and Dede's front without any problem.

The rest of the girls scrambled over to the glazed women and an orgy of licking, slurping, sucking, and rubbing broke out as they all chased a protein high.

My horsecock stayed hard, as I was now fully in the rut, and I grabbed Leandra by the waist and slammed the black squirrel beauty onto my cock, pummeling her pussy like it had my money. I watched my cock stretch out the sweaty abdominal blocks of her midsection, felt my cockhead violate her cervix, and enjoyed the sight of her bloated pecs bouncing as she tried to hang on with her 72" biceps, her huge fluffy tail swaying behind her as a counterbalance as I hurriedly jackhammered her into a cascading orgasm. My balls spooled up and delivered a massive load of jizz inside of the black beast and I let her pop off with the overwhelming flood of my cum, covering her rock hard pecs and abs with the rest of my spooge while I looked around for my next target.

Dede was sprawled out and spread eagled, presenting her pussy just above the puffy ball of floof that was her tail. My monstrous cock rose to the occasion. I dove back into Dede's cunt in a very literal sense, hooked my hands to her gargantuan, head-swallowing traps, and rutted. My face was on her bloated, absurd, man-shaming pecs and I licked and sucked like my life depended on it as my balls slapped her massive ass, my cock rippled up her abdomen's tunnel, and my hands clenched her traps even harder. I made her my bitch, or maybe vixen, as I rode her hard and blasted a monster load right into her fertile womb. She was scrunched up by the opposing forces of my hands on her traps and my balls trying to forcibly dislodge her by overfilling her internal organs. She finally slipped off and got glazed by the rest of my colossal load, and the next, as my balls churned constantly to restore the seed now.

I turned to Jia Na, my mouse wife, then and approached her, ready to push her down and rut. Her head, almost completely hidden in the sea of muscle compromised of her traps, delts, lats, and pecs, watched with amusement as her huge arms easily broke free of my grasp. She waggled a finger at me and easily knocked me onto my ass with her one free hand, quickly straddling me and moving to mount. She battered me briefly with her enormous breasts before shoving my pulsing rod into her itty bitty love canal. She rode down to the hilt and leaned forward, blocking out all the ambient light with her massive frame. Her huge arms easily held mine down as she smothered my chest with her titanic tits. I could just see her face inside of her hypertrophied muscles and she was grinning wildly. She rode sedately, at her own pace, denying the fury of my breeding instincts. I diligently tried to buck against her own motions, but she kept me mostly still without any visible effort, simply milking me in her own time. If I got too excited, she'd slap me with her tail. She was in complete control and loving it.

The orgy continued, of course, and left me horrifically dehydrated and weak for a couple days afterward. But they were all pregnant. Except Danielle. A few more women from Jia Na's experiments joined us from time to time, and most of them ended up pregnant as well. Chimeric alterations included hyperfertility at the baseline. Something Jia Na didn't realize at first.

Not until she discovered she was pregnant with 15 kids.
