Dinky ran her hands through her wet blond hair as she stood in the expansive shower, closing her yellow eyes as she arched her back inward. The steamy water splashed and coated her cute lavender fur, glistening upon her young curves in the rays of sun cutting through from the window above. Her lovely muzzle turned to a smile, arching her back and letting the water cascade upon her chest. Her ears twitched as she heard the door open, turning curiously to find her sister Chirpy. Chirpy smiled and approached Dinky, playfully wrapping her arms about Dinky's waist. Dinky cooed teasingly, feeling her sister's body press firmly to her back. Chirpy bit her lower lip, always loving being so close to Dinky. Time seemed to stand still as the two shared an intimate moment, stroking hands upon the other. The heat of the water steamed around the two as Chirpy's hands squeezed their way down Dinky's sides and hips.

	Dinky bit her lower lip, feeling her heart beat faster as she rolled her mouth closer to Chirpy's. Chirpy released a soft low moan as their lips met into a deep suckling kiss. Chirpy's fingers dug against Dinky's hips and inner thighs, causing Dinky to smirk. In one fluid motion, Dinky twirled around and pressed her sister against the wet wall. Their mouths met in a passionate full kiss, tongues dancing together as they shared moans. Their bodies bumped against each other, rubbing their wet young cunts together as they moaned passionately. Their hearts beat against their young chests, panting into their maws as Dinky pulled back.

	“Aahh... hhaaa... oh sister...” Chirpy sweetly panted out, batting her eyes. “ I need you so bad~”

	“Hrmm, I know.” Dinky replied in a matter-of-fact tone. Dinky pressed harder to Chirpy, asserting her dominance and superiority.

	“Please, sister~ Let's fuck like animals!” Chirpy pleaded and begged. Dinky bit at her sister's neck, making Chirpy shake and moan needingly.
	“I can feel your heat rising, but let's up the ante, hrm?” Dinky replied with a playful grin. Chirpy whined a bit as Dirpy pulled back. “Wait in my bedroom, little sister. I know of something that'll just break you!”

	Dinky trotted in to the local book store, wearing a hastily put-on dainty white one-piece dress, going to a straight b-line right to the book she had noted the last time she was here. Her grin turned wicked as her fingers curled to the hard spiral edge of the tome, sliding it off the shelf and holding it close to her bosom. She turned upon her heels and dropped a sack of bits before the counter, having added extra to buy silence. Dinky smirked coyly to the male cashier, who whistled innocently, acting like he never saw her. Dinky made sure to sashay her little lavender butt to the boy, the delightfully delicious idea of using the book on him after she broke her sister flitting to her mind.

	Dinky swayed her curvaceous butt back home, smirking all the way, her mind running with perverse imagery of what she would do with Chirpy. Passionate scissoring, smashing their milky large breasts together, pulling Chirpy's new long hair, spanking her little sister's expanded fat butt, Chirpy's broken moans echoing out. Dinky licked her lips slowly, her fingers curling against the firm hardcover back of the large book. She rolled open the door and smelled Chirpy's lingering scent, undressing as she followed it up the stairs.

	Dinky swung open the door to her room, her eyes falling into a smug bedroom gaze as they fell upon her little sister. Chirpy lay flat on her back atop the mattress, legs spread out already with her hands stroking upon her inner lavender thighs, fingers curling just along the edges of her moist filly cunt. Dinky flipped the ancient book open, Chirpy letting loose a gentle giggle.

	“Is my big sister going to tease me by reading as we play?” Chirpy said with a soft rolling murr, her fingers stretching her cunt lips out teasingly. Dinky's horn glistened with a mix of lavender and sparkling orange as she settled on a page. Chirpy's eyes widened momentarily as a magic bolt flew from Dinky's horn, enveloping Chirpy's pussy and making her spasm as her libido shot up, making her pussy moist, her body heating up and aching with need! Chirpy arched her back, humping her hips back and forth, fucking the air itself as she panted heavily, sweat coating every inch of her body in mere seconds. Her hips hit the air over and over with spastic humping thrusts, her pussy slick with her filly juices. Dinky cooed as she watched, groping her fingers down her belly to her own snatch. With a cry of ecstasy, Chirpy's eyes opened wide and rolled back, her hips hitting high to the air! But instead of filly juices, what surged outward instead was a thick juicy throbbing hard erect pony dick, complete with hefty balls full with hot gooey pony seed.

	Dinky trotted in closer, her fingers curling against the lips of her pussy as her body squirmed form head to tail, her hips rocking forward as a fatter heavier dick grew forth, balls dangling deliciously between the lavender filly's thighs. Dinky slid her index finger down the arch of her bulging meaty girth, her impressive log twitching heavily as it pointed upward. Chirpy gripped the base of her own twitching meat, her maw open in a lewd panting goofy grin and her eyes transfixed by Dinky's hefty cock – but Dinky wasn't done yet! Another surging bolt of magic flew from her horn and rushed through their young bodies. They both moaned out, their backs arching and fat cocks throbbing with strong veins as their hair surged outward into immensely long silky sparkling lengths, reaching down to their ankles with smooth flowing curves. Their cocks oozed thick goopy precum as their hips wiggled juicily, ballooning out to sustain their equally fattening asses. Not to be outdone, their flat chests tingled, making them squirm and bit their lips to quell a hot rumbling moan, their noises echoing out. Their chests swelled slowly at first as Dinky mounted atop her little sister.

	Their fat wet cocks pressed meatily against each other, the lewd wet slick sounds of their grinding muffled by their huffing moans, especially when they arched their back as their chests ballooned quicker and quicker, mashing their growing tits together wetly. The two sisters cried out, their wet tits slapping together as they pushed out to wobbling milky double-d's, and still swelled against each other. Dinky ground her body atop Chirpy's, smashing their engorged tits and intensely bulging cocks together as their long hair bounced and swayed behind them magnificently. Every touch ignited their cocks and bodies, making them cry out just as Dinky grasped her sister's legs firmly and bent Chirpy's legs upward against her large leaking breasts. Without a word, Dinky just pushed her wide plump hips forward, her fat giant cock bending as it pressed against Chirpy's tight pussy, Dinky's hands curled tight to Chirpy's ample hips. Chirpy moaned and squealed out, her back arching against her bent legs, toes curling as Dinky bit her lower lip and released a low rumbling groan till pop! Her shaft surged forward with her lavender hips, hitting Chirpy's fat plot with a lewd smack.

	Dinky's cock twitched inside Chirpy's tight wet hot depths, both of them panting as Chirpy's arms wrapped around her sister's head, digging hands against Dinky's hair and back of her neck. Dinky showed her little sister no mercy, proceeding to ram her impressive not-so-dinky cock in and out like a beast, rutting and beating Chirpy's stretched pussy! She banged and nailed Chirpy into the bed, making it shake heavily, rocking the room with their lewd primal love. Chirpy wrapped her legs around her big sister's waist, Dinky's thrustshitting deeper, her fat cockhead flaring and stretching Chirpy's womb. Chirpy's hands went up, gripping at her sister's large milky breasts and squeezed with her hot wet moaning. Dinky made sure that her little sister felt every shove and every shake of the bed underneath them!

	Chirpy started to groan and moan out Dinky's name, but it all came out as drooling gibberish as Dinky fucked her little sister stupid, pummeling that brain with an overabundance of sex, drilling and wrecking Chirpy's sex selfishly. Chirpy broke down, her whole body spasming and tensing up suddenly as she came! Buckets upon buckets sprayed from Chirpy's engorged cock, splattering them both lewdly in thick goopy ropes. Dinky shook all over, rolling her tongue against her lips as she planted every fat twitching length into Chirpy's pussy, not stopping till her hefty futa filly balls spanked Chirpy's young snatch with each drilling thrust.

	Chirpy's eyes faded as her maw opened out in a silent long moan, utterly broken as her belly swelled out to look like she was nine months pregnant in seconds! Dinky rolled out a long muffled moan, her dick giving another visible twitch and making Chirpy's belly wobble out with lewd sloshing sounds, reaching a squeaking stretched beach ball size. Chirpy's body collapsed, fading and surrendering to the intense afterglow that surged into her. Dinky smacked her lips as she pulled out of her sister, her cock spurting with more of her hot sticky white seed, ropes shooting out across Chirpy's massive sphere of a gut, hitting the wall in front of them with a large audible splash! Her mind began to play images of what she could do with that cute boy back at the shop, and a devious grin broadened on her lavender muzzle.

	
	Dinky kissed Chirpy as they smiled, holding hands together as they sat upon the chair on their porch. They gazed out to the setting sun, nuzzled tightly to each other like perfect lovers.

	“How do you think our little ones are sleeping?” Chirpy softly asked, planting a kiss upon her sister's cheek. Dinky playfully squeezed Chirpy's fat butt before standing up.

	“Only one way to find out, sis.” Dinky giggled and together they walked through their house hand-in-hand. Dinky extended her hand to open the door, when she was interrupted by a sudden moan from inside! They blushed, looking to each other before slowly creaking the door open. Their cute unicorn daughter, Violet, was cutely huffing, the spell book they had found years ago in her hands Her chest sported fat hefty double-J breasts that hung inches above her lap, nipples lactating sweet young filly milk. Her vast silver mane draped down the bed and onto the floor, shimmering in the low orange light from the window. Poking out from between her vast cavernous tits was a fat trunk of a cock, throbbing with mighty need!

	Underneath their daughter Violet was their other girl, an identical twin unicorn sister they named Lilly. Her incredibly long mane pooled down the opposite side of the bed, her young maw open as wide as she could manage as she was suckling at Violet's giant orbs. Her tongue could be seen, smashed against the side of Violet's balls. Her lewd wet eager swallows echoed in the room, her eyes glazed already as she serviced her identical twin. Lilly's own new cock could be seen between her plump and perky breasts, nipples sticking out juicily as her hands wobbled the giant melons up and down, titfucking herself as her fat cock drooled.

	Dinky smirked as she turned to Chirpy, who returned with a perverted grin of her own. They licked their lips as they flew open the door upon their two daughters – and closed it right behind themselves. The house rocked and over-flooded with intense passionate moaning!
