Like mothers, like daughter. And then some.

"Mooom~" Lily mumbled around Anne's finger, still sucking off the mixed juices, "I feel kinda hooot~..."

"Ooh, I know!" Anne sounded as if she thought she had the best idea ever. "You'll totally feel colder if you, like, strip and stuff!"

Jamie had almost expected something like this, but Emily was blindsided by her wife's great plan, gaping up at her from where the horse girl was nestled in her cleavage. Lily's reaction, however, made Emily close her mouth and look at her daughter instead, this time bewildered.

"Oooh, that's, like, the best idea ever!" Taking a step back, Lily slipped off her shirt, dropping it down into the cooling puddle of cum. "You're totally right! I feel cooler already! Let me just..."

After getting rid of her plain bra, Lily also stepped out of her hotpants and panties, standing before the rest of her family stark naked, save for her cum-stained sneakers. The puffy nipples capping her pert breasts crinkled and stiffened in the cool air, but her whole body was still flush with warmth - or something else.

"Mmmh, I feel better already..." Lily moaned, her left hand sliding over her hip and towards the reddening slit between her legs. "But now it's all tinglyyy~..."

"Oh... oh god." Emily whispered, a hint of fear in her voice. "She's... she's like me, isn't she?"

"Like us, Emily dear," Anne replied, pulling her horse girl wife into a deep kiss before continuing: "We may be different now, but we're, like, still a family. And we always will be and stuff!"

Emily sunk back into Anne's bosom, her face bright red. She looked like she still wanted to say something, but a low, drawn-out moan from Lily made the heads of the other three women whip around to where she was standing.

Lily had buried three fingers deep in her snatch, her other hand flicking the small bean presumably peeking out of its hood, hidden by the blonde's palm. Staring down at herself through moist eyes, she grit her teeth against the lust cursing through her, as it did through all who got changed by Growth X-enhanced fluids.

"Why'm I, like, sooo horny?" Lily gasped, knees nearly giving out under the **** of pleasure. "I nnnhh.. need a dick inside me and stuff..."

Jamie, her throbbing cock still in hand, stared at her step-sister with wide eyes from were she was slumped on her chair. With Emily spent and Anne without suitable equipment, the futa was the only option. But seeing as she had already banged both her mothers, would helping out Lily really be something she'd be able to refuse, let alone want?

"Lily darling?" Anne interrupted her daughter's introspection, once again proving her one-track mind. "I think Jamie can, like, help with that!"

With Lily raising her head to look at Jamie, the redhead could see expression of wanton lust on her sister's face; eye's half-lidded, cheeks flush, mouth slightly open as **** moans rose from Lily's throat. It seemed the arousal had hit the blonde harder than it had Emily - or maybe she just wasn't too timid to show it.

"Mmmh, like, I didn't know it was that biiig~..." Lily began stepping over to her sister, her hands still going to town, eyes glued to Jamie's throbbing member. "Oh, uhm, I'm Lily, by the by!"

"Yeah, I know, I, uh, was James," Jamie tried to explain, but it was pretty clear Lily wasn't really listening, all attention focused on the fat prick between the futa's legs.

"Mhmm, that's totes cool and stuff, but, like, is it alright if we fuck now?" Lily asked, already straddling Jamie's stretched-out legs, wetness glistening on her thighs and fingers. "I feel sooo empty, and your fat cock looks, like, reeeaaal yummy!"

Instead of answering, Jamie let go of her dick, grabbing hold of Lily's hips, who responded with a happy squeal and began lowering her hips. She only removed her left from her snatch once she felt her sister's drooling head touch her knuckles and then only to grab and guide it inside her waiting hole. Lily's right never left her clit, pinching it between two fingers as she tugged it up and down.

"Oooh, just the tip already feels so..." Trailing off, Lily lost no time to lower herself onto Jamie's lap, her cunt gobbling up the futa's straining member in one go. Even with as little preparation as she had gotten, Lily's insides were sodden, every fold wrapping around and clinging to Jamie's prick, the sweltering heat enough to make her throw her head back and groan with lust.

"You... mmmh, like my naughty pussy?" Lily moaned, twisting and shaking her hips on top of her futa lover. "It really likes your cock, too! I don't think it, like, wants to let go..."

As if to demonstrate, Lily rose a little, and indeed, Jamie felt herself sucked back in, the void her cock left **** to be filled again. With Lily dropping down again, groaning happily, the futa's purple, swollen helmet bumped against the entrance to Lily's womb, making the blonde twitch and tremble as she kept slowly rising and falling on top of her sister.

"Oh god, you're, like, literally the biggest I ever had and stuff," Lily gasped, her free hand now grabbing one of her tits, pulling, twisting, pinching the stiff nipple that capped it with two fingers while the rest of her hand massaged the sensitive, heaving orb.

Even with her mental faculties ravaged by lust, Jamie found the time to be thankful that Lily didn't seem to be changing anymore beyond the obvious. Emboldened by that fact, the futa grabbed her sister's hips tighter and began thrusting, meeting the movement of the blonde's hips with wet smacks of flesh on flesh. Lily rewarded the sudden change of pace with a surprised, excited squeal!

"Ohmigosh, yes! Pound my pussy, give it to me!" Throwing her head back, Lily shouted her pleasure to the heavens, or rather, the ceiling. Anne, or maybe Emily said something, but Jamie was altogether occupied with the bouncing bitch on her lap.

Alas, the futa still hadn't recovered fully from her pussy being broken in for bigger things by Emily, and the strength soon left her, leaving for Lily to do the lion's share of the work. The blonde thus opted for a more sedate pace, truly savoring the feeling of being filled by her futa sister.

"Oooh, like, you're filling me so much, you're making my clitty pop out or something..." Lily cooed, switching her hand to her other nipple.

Jamie's eyes flew open, and the futa felt as if she had been doused in ice water. Not that her cock faltered or anything, the way Lily was gyrating her hips made sure of that. But as she craned her neck to stare down to where their bodies were joined together, she found her worries made flesh. The fingers that had been pinching a tiny nub were now tugging an almost bean-sized, reddened protrusion. Which, with every pulling motion, gained a few fractions of an inch in length - and girth.

"Oh fuck, Lily, you're changing!" Jamie gasped, unable to wrench her eyes away as Lily yanked her clit to the size of her pinky, her hips shuddering when she wrapped her whole hand around it, the oversized clitoris disappearing from Jamie's view. But the futa was sure that she'd see it again very soon.

"I so-oooh don't care," the blonde groaned, continuing to bounce up and down on Jamie while clumsily jerking off her clit. "It feels, like, beyond am-ah! Amazing!"

And this amazing sensation translated into uncontrollable twitching in Lily's snatch, squeezing Jamie's cock exquisitely. Biting her lower lip, the futa tried to stifle a groan and raised her head to look at Lily. On the blonde's face was an expression of absolute bliss, with her eyes closed and a wide, slightly slack-jawed smile on her lips. Where Emily had tried to fight the lust, only to inexorably lose, Lily had given in from the very start, riding the wave higher and higher. Who was Jamie to deny her, really? Why worry if she could just do it like her step-sister and give in?

"Then take it, you slut!" The futa grunted and began thrusting again, using what little strength she had recovered.

"Aannh, yes! I'm your little slut, so fuck me! Harder!"

Jamie could now feel Lily's hand rub against the futa's stomach with every stroke, but that wasn't the only thing that felt different. Not only did the hips Jamie was holding on for dear life feel a bit wider, but the muscles moving under the healthy layer of fat seemed to bunch up and swell with every rise and fall of Lily's generous ass. Giving her sister a once-over, briefly distracted by her bouncing breasts, Jamie realized that this seemed to happen everywhere on Lily's body. Already she'd gone from lithe to toned with no sign of stopping. What did stop, on the other hand, was the futa's thrusting; she simply was too sore, her muscles still like jelly.

"Ooh, I love your dick..." Lily moaned, using her kegel muscles to milk her sister's cock while she moved her hips in a circular motion. "But my clitty, like, is almost as big as a cock now! Look!"

Jamie didn't look, Jamie boggled. While the futa had been distracted by Lily's swelling muscles, the blonde's clit had quadrupled in size, a small slit having opened up at the tip. Which looked suspiciously blunt. Lily was still working it with abandon, spreading the copious juices gushing from her slit all over the throbbing appendage so it was nice and slick. As Jamie looked on, its color began to lighten, turning from red to pink, the growth never stopping. Already Lily could move her hand a few inches up and down - and would probably have forgotten to move her hips if not for the bucking into her fist.

"Oh gaawwd, I can feel it, like, throbbing and stuff!" Lily groaned, rubbing her thumb over the little ridge that now ran around the tip of her clit-cock. "I... I... I think my boobies are getting bigger."

Growing boner momentarily forgotten, Lily stared down at her chest wide-eyed, Jamie tilting her head to look up - a fair bit farther than she had expected. It seemed while they had been distracted by Lily's swelling clit, the blonde had packed on not only quite a bit of muscle, but also height. Whereas before, Jamie would have been able to reach her sister's face had the futa been sitting upright, now she'd barely be able to reach Lily's neck. But it was below that neck where their eyes were drawn to: Lily's boobs, about as big as Jamie's when she had first changed, now surged bigger as if trying to catch up with the rest of her body. Soft flesh was already bulging out between the blonde's finger, the nipple capping it twitching and pulsing as it swelled.

"Oh--Ohmigosh, lookit them go! It feels, like, so tight on my chest..." Lily squealed, bringing her other hand up to maul both tits at the same time. Jamie felt her sister's throbbing clit-cock slap onto her stomach, slowly inching up towards the futa's bellybutton. "Do you see that? Do you think they're, y'know, envious of my clitty?"

"I... I dunno..." Jamie mumbled. The sight of her sister's swelling tits was almost hypnotic, the futa's jaw hanging slack as her mind went blank. She felt her cock twitch and strain against Lily's walls, which seemed to remind the blonde that, no matter how fun playing with her blossoming tits was, there was still an incessant itch deep inside her that needed to be scratched. Not letting up on her boobs, Lily began to thrust her hips back and forth, side to side, figure eights, all to feel Jamie's cock stretch her cunt every which way.

"Aww, you like my new titties, Jamie?" Lily giggled, leaning forwards until she could bury the futa's face in her deepening cleavage. Jamie felt like she was losing her mind, bucking her hips into her sister uncontrollably. Only her recent climax prevented her from cumming then and there. The feeling of Lily's breasts inching forwards along the sides of her head, their softness, the feeling of their weight on the futa's shoulders as they became more and more massive... it was sublime. It was intensely erotic. It overrode all restraint Jamie might have still had, all soreness forgotten as she started humping into Lily's snatch uncontrollably.

Wrapping her arms around her sister, Jamie found that she barely reached the blonde's spine, strong muscles rippling under the skin. Nevertheless, it gave Jamie enough purchase to pull herself deep into the taller girl's cleavage, drinking deep of her scent. Sandwiched between them, Lily's cock kept growing; it was already big enough for Jamie to feel the medial ring pressing into her belly. Of course, with her sister's increasingly gigantic tits in her face, Jamie barely took note of this, instead humping away almost instinctually.

With her ears now covered in abundant titflesh, Jamie could only hear Lily's gasps and moans as they traveled through the blonde's own body, but that was more than enough to tell that her lust was rising again after the short mammarian interlude, and quickly. And with her head buried between two tits that were fast approaching the size of Anne's, Jamie knew that, no matter how drained her balls were, she herself wouldn't be able to hold on for long, the incredible experience of being sandqiched between a pair of rapidly expanding tits decidedly to much for Jamie.

Which was why the redhead was equal parts disappointed and glad when Lily righted herself again, Jamie's hands sliding back down to the blonde's hips. At least now, she could marvel at her sister's breasts as they hung above her like twin clouds that promised bountiful rain. They were massive, eclipsing even those of their mother in sheer size; but in relation to Lily's equally enlarged body, they seemed far less outrageous. Where Emily was like a cute, timid little Shetland pony, her daughter was built like a draft horse, strong, bulging muscles barely covered by a layer of fat that provided Lily with a feminine physique despite all her power.

Her face had barely changed, only having grown to match her body, while the expression on it hadn't changed at all; Lily looked as if she was barely able to form a coherent thought due to the rampant lust assaulting her senses. Not that anyone needed her expression to tell: Lily's former clit had grown enormously as well, now a throbbing, bestial cock much like Emily's, only the blonde's seemed massive even on her draft horse body, almost poking against the underside of Jamie's tits. The futa felt its weight press down on her, the heat emanating from it reaching her very core.

"Wooow, look at my little clitty," Lily giggle-moaned as she gathered her heavy rod up with one arm, pulling it against her body while her other hand danced over her boobs. "It's, like, a reeeaal big clitty now!"

She started bouncing up and down again, the chair and Jamie's hips creaking and groaning every time Lily slammed her pelvis down, then nearly lifting the futa up from the chair as the blonde's cunt clamped down when she stood back up. How could someone so big be so tight?!

"Hnnaah, your cock is totes the best everrr! I, like, never wanna take it out!" Lily squealed, so engrossed in her bouncing that she didn't seem to notice her shaft was still lengthening, still thickening. Jamie did, and she watched with as much attention as Lily's cock handling allowed her as the mottled pink horse cock crept upwards towards the blonde's jiggling breasts, until it finally slipped into the valley of her cleavage.

"Oh! My! Gosh!" Lily cried out between bounces, crossing her arms under her breasts, lifting them up and together while her hands played with her nipples. "I'm, like, titty fucking myself! This feels--ahn! Amazing!"

Jamie had to concur, although for her, it looked amazing. The sight of her sister's gargantuan tits wrapping around the arm-like shaft made her cock lurch and swell inside Lily, and the way it tingled and throbbed told the futa that her climax was fast approaching. Not that Lily was faring any better, judging by the rising volume of her moans.

"Ohmigosh, oh--ohmigosh, it feels weird, my clitty feels weird, I think I'm, like--oh gaAWWD!"

With a rising scream from its owner, Lily's inhuman cock exploded, cum shooting out with enough **** to splatter against the ceiling, a few more shots arching through the air to rain down around them. Her pussy, meanwhile, clamped down so hard on Jamie's twitching member that the futa involuntarily drew up her legs, crossing her ankles - and then came herself. The tightness of Lily's cunt slowed the ascent of her cum considerably, thus prolonging Jamie's orgasm, but finally, with a strangled cry, the futa painted her sister's inner walls white.

With a happy sigh, Lily fell forwards, knocking the air out of her sister and hugging her tight; a motion that Jamie wearily reciprocated. With her arousal abating, the futa's whole body felt sore again, even more so than after she had banged Emily. Jamie just hoped this wasn't going to be a regular occurrence, but with the way her life was going recently, she wasn't so sure.
