"Oh dear!" I (Ms. Adams) kneel down in front of you, giving you a big hug, squeezing you against my overly massive chest (a solution that works for almost all my students) during recess. "What's the problem, dear? Is it about your 'special thing'?"

I (Haley) blush, and my soft 30 inch cock twitches. "Um, yes Miss Richards. It's really hard to concentrate in your class!" I press my face into your huge, soft breasts a little harder. "My, um, balls... they feel really really full and it kind of hurts, and- and it's hard to listen to what you're saying because I can't stop staring at you," I whine, and blush even harder.

"Ooh, that's okay Haley!" I begin tugging down your pants, my eyes going wide as your impressive member. "Hard alr-" I quiet as I heft your cock. It's still...soft?" "Haley, you’re bigger than I thought!" I heft your unbelievably dense balls, far too large to fit in one hand. "You’re so backed up… Let me help." I start tugging your cock as it comes to life.

I moan in pleasure as you fondle my cock, the thick slab of girlcock quickly lengthening and growing thicker as precum spews out the slit by the ounce. "Oooh, be careful Miss Richards, it's sensitive! T-Thank you for helping me though..." I lean into your boobs as my already beach ball-sized balls churn and swell with cum.

God, how big is this thing gonna get? I wonder as precum begins coating everything. I quickly strip down naked, hugging your titanic erection as pre coats me liberally. I begin using my titanic breasts, rivaling your churning nuts in size, to stroke your massive member. Is the classroom gonna survive this?

I whine with need, my balls churning even louder, now big enough to sit on. Even with their enormous size, I know I let out far more cum than should be possible - ever since my cock and balls started becoming active a couple weeks ago, we've had trouble finding places for me to unload safely. My throbbing cock approaches, then passes 5 feet in length as I admire your incredibly curvy body and huge boobs. "You're really pretty, miss," I blush as I cover you with precum. I'm sitting on my huge balls now, just trying to enjoy the sensations you're giving me. "I think I'm going to cum soon... Is it okay if I do it in here?" I moan.

"I think so… not that we can move you anywhere. Just get it all out of those packed balls, Haley. Shoot a big, BIG load, and we can try and start class again. Recess is almost over." I'm having trouble handling your massive cock, but I stroke it all the same. This is going to be messy...

The gush of precum from my now fully hard, five-and-a-half-foot cock is increasing by the second, and I steel myself for a mind shattering orgasm; it always feels incredible when my mom helps me, and you're almost as good as her. "Okay, here it comes, get ready- oh-" I scream in pleasure as cum rockets out of my cock, all the way to the other side of the room, hitting the blackboard hard with a lout splat. The first shot alone lasts a good ten seconds and puts out easily over a bathtub-full of cum. The second shot follows when the first tapers off just slightly, then the third, then the fourth...

I can't believe how productive you are! I watch cum rocket across the room, quivering in my own orgasm as I jerk your cock, watching you paint the classroom with thick sperm. So virile… The classroom begins to slowly fill as wad 8, then 9 shoots out. How many can she deliver? It almost seems like they're getting longer...

My screams turn into whimpers as my orgasm drags on and on. Along with the pleasure of orgasm, it feels sooo good to empty my aching balls - I've gone far too long without cumming, a few hours at least. Finally, after nearly 3 minutes and 20 absolutely massive shots, the last dregs of cum splurt out of my softening cock, and I sigh in relief. The floor of the classroom is completely covered, the level of semen up to my ankles. "Thank you so much Miss Adams, that felt really good. Um, sorry I made a mess..."

"That's okay, Haley," I say, panting with pleasure. "Whenever you need to do it again, you just let me know." The class door opens, and your classmates begin to shuffle into the class, stepping carefully in the thick pile of cum, a few of them having to wipe it off their desks.

I slosh over to my desk and sit down, embarrassed. My balls are noticeably smaller under my skirt, but they still stretch it out massively, the size of basketballs at least. My cock hangs over them almost to the ground, already leaking a steady stream of precum to add to the lake of spunk in the room. I sigh, hoping I won't have to unload again before the end of the school day, but knowing I will.

-----------------------------

Annabel wakes up early and heads to mom's room, shaking her by grabbing her titanic titties. "Mom, should I wake up Haley?" she asks, her own prodigious bust ready to burst out of her small (for her) t-shirt.
"Mmm?" Your mom rolls over and gets out of bed. Her body and curves are out of this world… but you'll see them when you get up. "Sure, honey, let's go." Both women know to expect even more growth on their way to your room. Your size has only been gaining a few inches these past few days. They both strip naked as well, ready to get messy.

I yawn and open my eyes when the sunlight hits them. I start to sit up, but something doesn't seem right... I'm used to the constant smell of cum in my room by now, but I'm feeling awfully cramped in my bed. My eyes start to adjust, and I gasp: my cock is extended well past the end of my bed, rock hard and at least 8 feet long! On top of that, it's spewing a thick stream of CUM, not precum, onto the floor - my now even bigger balls must be so productive, they can't keep it all inside! Speaking of my balls, they're much bigger than I've ever seen them - I struggle to come up with something to compare them to. Beanbag chairs, maybe? No, probably even bigger. Finally, I notice my view is somewhat obstructed from below, and I realize I now have genuine boobs! I massage them with my hands - they're at least as big as my sisters, a big change overnight from being completely flat. "Mom! Annabel!" I call, slightly worried, just as I hear the door open.

The door opens, and a thick stream of cum pours into the hall, knee-high. Annabel steps in first, her titanic boobies bouncing like mad. Each one is comparable in size to a county prize-winning pumpkin, perhaps five times larger than her teenage head; they stand firm, but are so large they hang down to her thighs. "Sis! You got boobies, too!" she dives forward to hug you as your mom steps in. She is impossibly endowed; her tits stick out six feet in front of her, farther than she is tall. Each one is easily twice as large as a yoga ball, and together, they are almost as big as a small car. Her nipples stiffen, growing half a foot larger as the stench of your delicious cum hits her. "Ooh, somebody's grown," she says, heading straight to your overproducing head.

I giggle and hug you back, although the collective size of our busts means it takes some serious maneuvering. I have some mixed feelings about my developing body - it's hard to deal with sometimes, with how big everything is - but I have to admit I was jealous of your huge boobs. "Heehee, yeah! I was wondering when they were gonna come in." I take in the sight of both of your massively endowed bodies. They always turn me on so much, and my balls swell slightly, gurgling, and the stream of cum gushing out of my cock head thickens.

Annabel smiles, then turns to your titan cock. "Jeez, Haley, this thing is crazy!"
"We need to get this aimed out the window again," your mom says. Her boobs have grown slightly larger; they usually swell up a cup size or ten when she's turned on. "You're a big, growing girl! Help me out, Annabel."
Both women heft your cock and heave; you watch their enormously fat asses jiggle as they push your cock to flop facing the other side of the room. Asses like that break even the sturdiest of chairs; that's why you only have benches in the kitchen.

"Hehe, I know... I'm kinda still getting used to it, I guess..." I squirm uncomfortably - then moan softly in pleasure as the two of you handle my cock. Despite its size, it's even more sensitive than it was before, and I can already feel myself nearing orgasm. It doesn't help either when I see your two enormous, thick, round asses jiggling in front of me. Suddenly curious, I move my hands down under me and find that my own butt is much thicker and bouncier than it was before - it doesn't compare to either of yours, but it's easily bigger than any other I've seen.
The room is awfully cramped with the outrageous size of all our endowments - mom's car-sized tits especially taking up half the room - but the two of you, with some heaving and grunting, manage to position my gushing cock at the window, resting the head just beyond the window frame. I'm still moaning slightly with every touch. "T-Thanks guys... It's really sensitive right now, so this could be quick, but... could you rub your boobs against it?" I ask sheepishly.

Mom and Annabel both giggle, digging their enormous nipples into your shaft, rubbing back and forth along it, your mom's nipples large enough to put any cock but yours to shame in sheer length. Mom the heaves and lifts her boobs high, sighing as she drapes them over your immense cock, which easily supports their weight. "I just emptied the pool outside for fall," mom says, grinning. "Care to fill it back up?"
"I'm gonna swim in it and get pregnant again!" Annabel cries. "I'll give you quadruplets again, sis!"

It's hard to pay attention to what the two of you are saying, the pleasure of your soft breasts and hard nipples on my cock making it difficult to not immediately blow my load, but I respond. "Mmnnn... I don't know h-how much is gonna come out, but I'll try. I-It might even b-be more than- O-Oh, I'm cumming-"
I'm cut off as I scream in pleasure, my first rocket of cum of the morning aimed right at the empty pool, hitting the bottom with a loud SPLOOSH. I quickly run out of breath and simply lay there whimpering, with my eyes glazed over and my tongue hanging out, as the first shot easily fills the bottom of the pool. It's difficult to tell where one shot turns into another, but it's been a minute now of mind-blowing pleasure. It never felt this good before...

Your mom knows almost immediately that the pool, and the whole backyard, is done for. "Wow..." she cums simply from feeling your pulsing cock under her tits. Annabel masturbates herself, cumming again and again as your wads bring the pool to half full, three-quarters full... "You did it, sis!" she cries, cumming again. "Are you still cumming? How do your balls feel?"

I'm still almost delirious in pleasure, but by this point I've gotten it together enough to respond. "Ooohhh... Y-Yeah, feels like I'm a-almost done- Mmmph!" The nearly continuous blast of cum is overflowing into the yard, covering the ground all the way to the back fence and through it. Cum slides down the slope below the fence as my incredible load dwindles, the last few hundred gallons of thick cum spurting out as my cock starts to soften. Finally it's over, and my 3 foot limp cock slops onto my now yoga ball-sized nuts. They're churning happily, but I can already feel them rapidly filling with cum in preparation for the next load. I groan loudly in satisfaction. "I think I'll be okay for awhile now..."

"Really?" Annabel teases, rubbing up against your titanic nuts. "I bet you're gonna cum three more times before school!" she runs off downstairs, undoubtedly to jump into the cum-pool.

My nuts churn loudly in response, clearly answering for me. The thought of you swimming in my cum, getting massively pregnant with my infinitely fertile seed, is enough to make my cock start rising again. I sit up and sigh, frustrated that I'm never able to enjoy the feeling of having empty balls for long. "She's right, mom, I'm gonna need to cum again..." I look over at your titanic tits and smile.

"Then let's get you outside, dear." Your mom pulls you out of bed and quickly downstairs as your cock hardens, spewing bathtubs of messy cum across the stairs and hall before exiting to the front yard. "Remember when you first knocked up mommy?" she asks. "We're going to do the same thing… only, you're a bit bigger..." your mom gets down on her tits, resting atop them even as they swell with pleasure, wriggling her glistening, soaked snatch at you.

My mind goes back to when you helped me unload just after I started developing, filling you up massively with my cum, even with my MUCH smaller loads. Combined with the sight of your dripping pussy and glorious, round ass wiggling in front of me, I'm positively drooling with lust. My cock is completely hard now, spewing cum all over you and the rest of the yard, and my balls are already aching to release their next load. Wasting no time, I fumble to line up my enormous cock head with your needy pussy and push in, loudly groaning in pleasure.

My boobs wobble and bounce as you thrust into me, growing even larger along with my belly, which begins rapidly filling with sperm. "I bet I'm pregnant already!" I cry out, feeling my womb swell with just your constant fire hydrant flow of cum. "Pound it all into me, baby! Bloat me massive! I want all of your babies!"

"I will, mommy!" I yell over the loud gush of my thick cum into your belly. My balls are on overdrive, loudly churning out enough cum to fill a bathtub every few seconds - and I haven't even reached orgasm yet! My hips thrust back and forth rapidly, practically on their own as I'm completely consumed by lust. I just love the sight of your fat ass split by my cock, your massive tits jiggling and swelling with arousal, your already overfilled belly bulging with an outline of my absurdly massive cock. I can feel my cum slit start to widen, and I know another massive load is approaching. "I'm g-gonna cum, mommy, get ready!"

"Give me an enormous load, honey! Empty everything out before school!" My unbelievable ass begins wobbling like mad before your eyes; it couldn't even fit on a couch, the soft flesh waving in near-hypnotic patterns as I begin rising higher off the ground from my overfilled belly. How much will she cum? God, what if I overgrow the neighbor's house? Hopefully they’ll see my shadow beforehand…

I scream in pleasure as hundreds of gallons of glue-thick cum explode out of my cock and straight into your womb in mere seconds. You quickly begin to tower over me, your belly expanding at a terrifying pace. Even if we weren't both impossibly fertile, there's no way you wouldn't already be pregnant with a record shattering number of babies. My massive cock puts fire hoses to shame as you reach the size of our living room in under a minute, and my constant gush of cum only increases in power.

I can only hold on for dear life, hoping I won't be blown away by your prodigious orgasm. I think of the backyard, and the damage you inflicted on it… and I think of how all that, and more, is being pumped into me. I cry out in thunderous orgasm as my swelling form begins to grow up a story in height… out onto the street… knocking over the mailbox...

It's hard to notice through the pleasure, but I can see how huge you're getting - even your enormous ass and car-sized tits look tiny in comparison to your now house-sized belly stuffed with my cum. I moan continually, my tongue lolling and my eyes glazed over as my orgasm drags on and on; the incredibly sexy sight of your body keeps drawing more cum from my grossly overproductive balls. Finally though, after about five minutes of constant orgasm, the gush of cum starts to decrease...

I can feel it pressing against my belly: the neighbor's house. Across the street my womb has been overstuffed, and as you come down from your titanic orgasm, my belly bursts through the front of the house, a giant fleshy wall invading the neighbor's space. I can't even moan an apology, I'm so lost in pleasure. How many kids will this be? A dozen? Two dozen? 50?

I sigh in contentment as the last dregs of my load, still nearly enough to flood a room, empty into your seriously overstuffed womb. My hips are pressed firmly against your fat, bouncy ass, the cheeks much too thick for any cock but mine to even reach through them to penetrate you. "Thanks mommy, that felt sooo good," I whimper, although you don't seem like you hear me. I walk backward to pull my cock out of you - the second the beach ball-sized head pops free, a torrent of incredibly thick spunk gushes out of you and into the yard.

-----------------------------

(After school...)

After jumping off the school bus, you feel ready to burst. Your cock drooled precum all over the bus floor, and you can't wait for your mom to help you get off. Even soft, you nearly feel ready to pop...
As you walk up the street, you see your neighbor, Isabel, out in the garden, bent over. Her hugely fat ass sticks out, her jean shorts wholly inadequate for them, her tank top pulled high to try and contain her enormous, fat tits.

I step off the bus after the flood of precum gushes out. I'm pretty embarrassed about all the mess I'm making - The school is now pretty much flooded with cum, even though I made sure I only unloaded in the field out back - but my desperation to drain my aching balls overcomes my self-consciousness, and I race home with my gushing cock over my shoulder so my mommy can help me out. On my way, though, I take notice of Isabel's fat, round ass jiggling as she does some stretches. I gulp and blush slightly, the stream from my cock turning from precum to cum as my overpacked balls start getting ready to unload. I make my way over to her, cautious but eager, dragging my enormous bean bag chair-sized balls behind me. "H-Hey Isabel, how's it going?"

She turns to you, and yelps in surprise. "H-Haley!" she cries. You watch her face grow flustered as she stares at your giant prick, gushing cum all over the yard. "Oh my goodness… you look so backed up… let me help!" Isabel eagerly jumps forward, latching her mouth onto your fat cockhead, stretching wide as she goes further down, until the weight of her own belly, heavy from your output, immobilizes her.

I yelp as Isabel greedily latches onto my gushing cock and drinks down gallons of my thick cum. I didn't expect her to be this eager to help, but I'm more than okay with it. "Oooh... Thanks Isabel, that feels really good..." I continue moaning softly as her belly bloats to the size of a beanbag chair, my thick fuckmeat rapidly hardening and expanding to a good five feet and rising. It's not long before her shorts and tank top burst, revealing her deliciously curvy and plump body, which only fuels the massive load my balls are churning up. It occurs to me that as of this morning, my boobs and ass are way bigger than even hers, and I begin rubbing my own huge tits along my shaft, moaning in pleasure with my tongue lolling out.

Just as you begin pleasuring the other parts of your body, the front door opens. Out come two twins, Dani and Lori Richards. The college sluts are dressed in their skimpiest outfits, ready to party tonight, their fit, toned bodies on display. "Ohmygod look!" Dani cries, pointing to you and Isabel.
"What is that beastly thing?" Lori yells. "She's filling up Izzie like a blimp!"

I begin frantically thrusting my hips as my cock reaches full hardness, spewing incredibly fertile cum into Isabel at an ever increasing rate. My mind is almost lost to pleasure, but I notice the twins gawking at me, their nipples clearly hard through their minuscule crop tops. "Hi," I manage to blurt out weakly - it's all I can manage with the overwhelming pleasure I'm feeling.

"Look at her go!" Dani says. She takes out her phone, snapping a picture of you with her sister as Lori approaches.
"You're so hung," Lori mutters, watching you fuck and bloat Isabel. "Gawd… can I help you after Isabel?"

"S-Sure- Almost- Nnngh!" I let out a silent scream of pleasure as my true orgasm hits, making my previous gush of thick spunk look like a faucet leak. It's a repeat of this morning, hundreds and thousands of gallons of cum exploding into Isabel every moment. In only a few minutes she's nearly as big as mommy was this morning, her absurdly overstuffed belly overflowing onto the street as my last few tub-filling shots burst into her. I sigh in relief before walking backward, pulling my still rock hard and gushing cock out of the dazed girl. "Oh wow, that felt sooo good. I'm still feeling really full, though... Um, could one of you help me?" I ask shyly, my balls already churning loudly as they refill.

"Me!" Lori cries. Both girls have already stripped, Lori running forward to grind atop your cock, cum blasts soaking her from the tits down. "Oh my god, you're gonna get me so pregnant..." she impales herself on your cock, crying in pleasure. "So big!"

I groan loudly myself as Lori stretches herself over my gushing girlcock. I didn't know these girls were so eager to help me unload - I'm going to have to come over here more often! I get back into a rhythm, thrusting my hips back and forth rapidly, although compared to the extreme length of my cock it doesn't make much difference. I notice Dani furiously fingering herself under her panties, whining at having to wait her turn - apparently she tries to make the best of it, as she jumps on top of my throbbing shaft and grinds her pussy along it, reaching orgasm almost immediately with a loud cry.

Lori and Dani are in the throes of mighty orgasms as you begin to inflate Lori. Their younger sister watches, cum dripping out from her distended cunt, while Lori passes the size of a couch… a car… Dani begins to worry the slightest bit. Does this girl ever stop? she wonders, even as she crests in yet another orgasm. She's gonna fill my twin so huge...

My second load in ten minutes is signaled by a loud groan and a GUSH that sounds like a fire hose as Lori's cum inflation increases rapidly. Once again, like her younger sister, five minutes of cum straight from my obscenely overproductive balls leaves her belly the size of a house, only slightly smaller than her recovering sister. It seems like my loads are slightly smaller each time I cum; in my post-orgasmic haze, I vaguely wonder how many times in a row I can cum. I pull myself out of Lori's bloated form and point my dick at Dani, who fell off of my bucking shaft some time during my monstrous orgasm.

She's out on her back in a yard packed with overstuffed belly, legs spread wide, ready to accommodate your cock. "Fill me up, Haley! You make so much..."

"Okay!" I'm feeling much better than I was when I got off the bus - I don't absolutely NEED to cum any more, but I'll take any chance I can get. Your sisters' bloated bellies block out our view of most of the neighborhood as I eagerly push my massive cock inside you, stretching you out on the head like a human condom.

"Best to let it all out of your system," a voice says from behind. Standing there is Ms. Richards, a sultry, overly busty older woman (though nowhere near your mother's size!). Her tits are contained in only a small towel, one that hangs far too short to cover her bare pussy. "How are you feeling, Haley?" she bends down to her knees and hugs you from behind, digging her enormous tits into your back. "Are you gonna impregnate all three of my daughters?"

I recognize that voice, and blush - I've fantasized about Ms. Richards ever since my cock started becoming active. Even though she's not as curvy as my family, her body is still incredibly sexy, and her sultry voice and personality turns me on like nothing else. "Um, yes ma'am!" I squeak as I thrust in and out of the thrashing and orgasming Dani.

"Good girl. Give Dani here a nice, big load; she's wanted children for a long time. Maybe they'll be as hyper as you?" Ms. Richards giggles, reaching forward, her fingers gently brushing against the base of your massive cock as Dani cries out in pleasure.

I moan at her touch, the feeling somehow better than fully penetrating her daughters. I'm quite tired at this point, so instead of a scream I let out a soft squeal as, once again, I unload my juicy balls into Dani, and once again inflate her to the size of a house with five minutes' worth of impossibly potent cum. Sighing, I pull out. My cock has softened ever so slightly, and it's now returned to spurting precum again rather than the constant deluge of cum, but Ms. Richards is bound to change that. It's getting awful cramped in the yard...

As soon as you pull out, Ms. Richards tsks at you, shaking her head. "Just precum, now? Why don't you run on home, Haley; come fuck me when you've got enough cum to fill me bigger than all my daughters, combined." She gives you a pat before sashaying off to the front door of her house, her ruined daughters oozing cum onto the yard and street.

--------------------------------

(Mom) I'm out on the still-messy back porch with one of your many newborn futa daughters. I had been watching bellies soar in front of the Richards house, as I slowly sucked the baby's massive, 2-foot hard cock; looks like you'll be raising an army of hyper kids in no time.
Just as I hear you open the back porch door, your daughter Grace starts cumming down my throat. She smiles at me as she lays in my huge tits, firing gallon after gallon into me, swelling my belly up like I'm already pregnant again. This is just one of your 56 children I birthed, not counting the 22 your sister had at high school today. I look up to you as I swallow wad after wad of cum.

I'm still pouting from Ms. Richards' last tease as I walk in the door. She wants me to fill her up even bigger, just wait until my next growth spurt... I shake my head and come back to Earth when I see you and the baby, your tits even bigger than usual from the recent pregnancy.
"Hi, mommy! Is this one of the kids from this morning? What's her name?" I smile at you both, watching her massive output, her cock and nearly basketball-sized balls each as big as the rest of her body. I can't believe I used to think that was big...

I smile up at you, swallowing a thick load from your daughter. "Welcome home, baby! Her name's Grace. She's the biggest of this morning's load! She could probably knock me up with a dozen or more babies… How are you feeling? Do you need to cum? Did you cum enough at school today?"

"She is pretty big... I guess my growth spurt last night made me more fertile, too. School was okay... I only got to cum ten times, though, so I was really backed up when I got off the bus." I walk over and sit down next to you both, gushing out cum on the way as my cock drags on the floor. "The Richards girls helped me out, though... but Miss Richards didn't want to." I pout.

"Aww, how mean of her! Did she tease you?" I lick my lips, looking down to your leaking cock. "Your sister is inside, too, if you want her help." My engorged nipples begin to leak milk, and Grace instinctively crawls down to one, suckling away happily.

I watch as Grace suckles on your huge nipple, her soft cock still nearly as big as the rest of her body. "Mmhmm. She said she wants me to fill her up bigger than all her daughters combined, and not to come back until I could... Oh, I'm gonna go back there once I get a little bigger! That'll show her." I puff out my cheeks in frustration. "Um, okay. I guess I do still have some cum to let out..." I make my way down the hall, covering the floor with thick spunk on the way.

-----------------------

A few days later, Annabel is at home, taking a catnap. Her tits have been growing bigger recently, thanks to the milk that now-constantly leaks from her nipples. How many of your children has she birthed? 100? More? Either way, she just got home after delivering a few dozen, and she is pooped! Naked, she's curled up, using her enormous udders as pillows to rest on on her bed.
