SunsetBlues commission: The Shape of Penis

Lucian waves at the woman having just picked up her child from his daycare, the cute little boy waving back at his teacher as the door closes behind them. It’s late on a weekday and nearly all parents have retrieved their little ones after their daily grind, and the lop-eared rabbit is waiting for the last one as his workers have left for home as well. The single fox mother had called ahead and apologised profusely, for she was stuck late at work and would expect heavy traffic on her way over. She would compensate Lucian if he could watch her little girl for just a few more hours. The lop bunny had told the single mom not to worry, that he would provide dinner and entertainment for her little girl, and that she shouldn’t rush.

Sitting alone in the middle of a colourful play mat sits a lone fox girl, her fur as white as snow and wearing a cute little blue dress as she’s suckling on a binky whilst playing with some blocks. The lop-eared bunny in his twenties, creamy brown in fur himself with just a few speckles around his shoulders and hips, is whistling a tune as he locks the front door. He’s been through this song and dance before, with a parent permitting themselves more of his time and often heavily compensating him for his trouble afterwards. Though, they don’t know just how much of a compensation the teacher affords himself, for Lucian is an avid lover of the cute little ones they leave in his care. And when left in such convenient circumstances, why, opportunity makes the thief, after all.

Little Ava, as the cute four-year-old fox girl is called, is unaware of her teacher’s intentions and is simply playing by herself when Lucian walks over and sits next to her on the play mat:”Hey there, Ava. Your mommy will be a little late but we’re gonna keep having fun, right?”
The preschooler nods as she keeps building a structure out of colourful blocks, the cute little girl sitting on her bum with her legs open wide as she does. Lucian makes himself comfortable, adopting the very same sitting position as he grabs a few blocks and starts building next to Ava’s structure, the girl smiling around her pacifier as she appreciates the attention of her teacher. The creamy lop-eared bunny male wipes his brown hair away from his handsome face, many moms and the occasional dad regularly swooning over him and occasionally approaching him for more. Lucian always rebukes them kindly and politely, for his heart and loins belong to those much younger in nature.

The teacher is observing the little girl closely, his heart starting to pick up in speed as he is edging closer to take the plunge. He’s been with many cute little cubs before, most of them too young to talk and thus ‘safe’, but Ava is already four years old and thus he needs to be a little more sly about this one. Make it seem as if they had just been playing a game with room for ambiguity should the little snow-white fox girl ever speak of what is gonna transpire here between the colourful four walls of the daycare.

Lucian picks up a block and holds it out for Ava, who tries to take it but the adult male withdraws the toy object at the last second:”Before I give this to you, Ava, sweetie. What shape is this?”
Ava looks up at her teacher’s face, then the block, and she seems to be thinking as her little hands squirm around each other. She then speaks, her pacifier slurring her words slightly:”Circwel?”
The lop bunny shakes his head and picks up another block, which is a thick circular one:”No, sweetie. This is a circle. A circle looks like a ball on one side, remember? This is a square.”
Lucian holds the two blocks up for Ava to view, the preschooler quietly suckling her pacifier as she slowly nods and reaches for the cube in her teacher’s hand:”Sqwuare.”

Ava is given the block and she uses it to build the next layer of her structure, looking up expectantly at Lucian again as if waiting for the next one. The twenties-something teacher smirks as he picks out another block, happy that his little ruse is working and taking seed in the girl’s mind:”Alright, Ava. What colour is this one?”
The preschooler looks intently at the block in her teacher’s hand, her binky suckling back and forth as she ponders. Colours are a bit easier as cubs learn them from an earlier age than shapes. After a few seconds, Ava says:”Gween.”
Lucian nods and gives the block to the little girl:”Very good Ava. What colour is your fur?”
Ava places the block onto the others, the objects wobbling precariously, but the little vixen is undeterred:”White?”
Again, the lop bunny nods, a stirring visible in his pants as he works slowly towards his goal:”That’s right, sweetie. And what colour is teacher’s fur?”

Again, Ava looks up at Lucian intently, her young mind trying to process on how to formulate what colour her teacher’s fur actually is. It’s a trick, of course, as Lucian’s fur is nuanced brown with more creamy complexities throughout, way too advanced for a cub to vocalise. Ava seems unsure and she doesn’t answer, just whimpering slightly, but Lucian quickly comes to her aid:”How about teacher shows more of his fur? Maybe that will make it easier?”
The preschooler quickly nods, sucking her binky as her eyes are fixed on her teacher’s face and neck, where most of his fur had been visible up until that point. Lucian undoes his shirt button by button, as if giving the four-year-old a little striptease, mostly just to arouse himself as he envisions saying the most naughty things to the cute little girl in front of him as he does. Eventually, his shirt is open and his toned chest and stomach are put on display to the little girl, brown and creamy in colour all over but with the speckles around his hips and shoulders now visible. Lucian’s nipples are dark in colour and stiff, erect out of sheer exhilaration of undressing in front of a girl this young:”So, Ava. What colour is my fur?”

This time, the little girl comes to a conclusion much faster and chirps up happily:”Bwown!”
Lucian is encircling his nipple with a finger, inwardly moaning as his cock gives a lurch inside his pants. He quickly nods, his breath a little husky as he says:”That’s right. Very good, Ava. What about you? Are you white all over?"
The preschooler picks up her fluffy fox tail and her ears twitch as she seems to think, looking at the grey end of her appendage and then mumbling:”Gwey?”
Lucian nods, still lazily tracing circles around the stiff sensitive nub of his nipple as his voice deepens even more slightly still:”Uhu. But I also know Ava is pink somewhere on her body. Do you know where you’re pink, sweetie?”

Ava seems utterly confused, looking at her arms and legs sticking out of the cute blue dress she’s wearing, but she can’t find pink anywhere. She looks up at her teacher with a confused look, and the adult male bunny gently pulls out the preschooler’s pacifier:”Your mouth is pink, sweetie. And your tongue. And there’s another spot on your body that’s pink… Wanna see where?”
Ava is completely absorbed by the ‘lesson’ and eagerly nods, getting her binky back as she deeply suckles on the rubber teat. Lucian smiles and gently lays Ava onto her back, the preschooler immediately and instinctively raising up her chubby legs as if being changed:”Then we’re going to have to take off your clothes as well, Ava. You don’t have to go potty, right?”
The little girl seems to think and then shakes her head ‘no’, which satisfies the lop-eared bunny as he lowers the little tot’s leggings and undoes the tabs on her diaper:”Alright, then. Here comes Ava’s pink place!”

Emerging from the diaper as it folds away, a blushing pink slit is revealed in all its splendour, chubby and fat and baby-like like little preschoolers tend to be. The chubby cleft is framed by two thick plump baby pussy lips, and a prominent little fleshy pearl at the top of the slit. The rosy lips are framed by tiny white hairs that grow into longer fur the more removed from the genitals, a cute little rosy pucker nestled underneath the tot’s fluffy tail as well. Lucian can feel his cock lurching in his pants, angrily trying to get out as his underwear is getting soaked by the copious amounts of precum he’s producing. The bunny’s nose is twitching something fierce, his eyes locked intensively onto the inviting slit of the squirming four-year-old fox girl, his buck teeth biting into his bottom lip as he gently runs a single finger from the top of Ava’s cleft to the bottom:”T-there’s Ava’s pink place. Right between her legs.”

Ava sits herself up more and keeps her blue dress raised with one hand whilst darting down to her own pudgy pussy as she touches herself with her equally stubby little fingers, smiling around her binky as she has found a new pink spot on her own body:”Pink!”
Lucian slowly nods and picks up another block, a donut-shaped circle as he holds it up for Ava:”That’s right, sweetie. And your pink place is shaped like this! What shape is this?”
Ava’s little fingers are still squirming around her plump little lips as she looks up, clearly making her private place feel nice and tingly as she suckles her pacifier and says:”Circwe!”

Lucian nods and picks up another block, his cock straining in his pants as he can smell his own arousal fill the air with his pheromones:”Very good, sweetie. Now, let’s see what this shape can do with this one.”
The perverted bunny teacher is holding a cylinder, its thickness made to match the hole in the donut block as he smoothly runs it through, his eyes watching for any reaction in Ava:”See? This block can fit in the other. Isn’t that funny?”
Clever girl as Ava is, she immediately reaches for the cylinder block. Lucian gives it to her, and the preschooler brings it down to her little pussy, rubbing the edge of the toy object against her chubby slit. The lop-eared bunny nearly suffers a nosebleed as he observes the four-year-old rub the phallic-shaped block against her puffy pussy, the rosy lips being parted and pushed aside as she clumsily tries to make it fit in her ‘donut’.

Eventually, Ava frowns and whimpers in frustration, looking up at her teacher as she holds out the cylinder block:”Does not fit? In my circwe?”
Already unbuttoning his pants, which bulges out lewdly as his cock underneath causes the fabric to strain with each flex, Lucian simply shakes his head and says:”It seems too big for your little circle, sweetie. But perhaps, if we find something smaller that fits, we can make your little circle bigger.”

Lucian moans out with a deep sigh as he frees his cock, the pink uncut humanoid penis slapping upwards and spraying a few strands of clear precum all over the play mat and Ava’s chubby thighs. Again, Ava can be a clever girl, and as her eyes regard the pink length of her teacher’s cock, she grins around her binky and eagerly exclaims:”Pink cywindwe! Pink xywindwe for my circwe!”
The horny bunny teacher’s cock flexes and spurts out another thick jet of precum all over his own groin, Lucian moaning as he runs his fingers over Ava’s little cleft:”Oh, yes. Good girl, Ava. But teacher’s block is still a little big for your circle. First we need to make your circle a little bigger…”

Barely able to keep up the ruse in his horniness, the creamy brown lop bunny gets onto his knees and without explanation dives his head in between the four-year-old fox girl’s chubby bare thighs. Ava squeals out in surprised delight as she feels her teacher’s tongue slather her plump pussy in a thick layer of his saliva, before closing his lips around the chubby cleft and sucking himself vacuum onto her vulva. The preschooler is overwhelmed and lays down onto the play mat, sucking her binky hard as her little heart races with unknown pleasures and excitement, staring at the ceiling as for the very first time she feels an adults tongue wriggle itself deeply inside of her private parts.

Lucian is in heaven, his bunny nose pressed tightly against Ava’s hard tiny clitty and his lips sucking his mouth tightly on top of that pudgy chubby rosy blushing baby pussy. His tongue swirls around the heated flesh of the preschooler, the taste of her innocence divine as he explores the sensitive rim of her lips and the rubbery texture of her immature vaginal canal. The lop-eared bunny in his twenties has a firm grip on his own shaft but has to hold back from masturbating, lest he explode immediately, only allowing himself to squeeze his length every now and then. Farther, his tongue worms down inside the sacred depths of the preschooler’s vagina, gently massaging the contracting fleshy muscles and applying a generous coating of his own spit for what is to come.

Ava is biting down onto her binky and kicking her legs out in uncontrollable motions of pleasure, inhaling deeply and grunting in her cute preschooler way. Her little hands are clutching and convulsing, grabbing at the mat and other objects without control, her tiny toes curling at the overwhelming waves of immature pleasure her teacher’s tongues washes over her. Her little blue dress is bobbing up and down over her crotch as Lucian’s head is hidden underneath in the four-year-old’s lap, the adult man lying in the middle of the otherwise abandoned daycare playroom with his head stuck under a preschooler girl’s dress as the lewd slurping noises and babyish grunts fill the empty space.

After what seems to be an eternity of bliss, the adult male lop bunny emerges from underneath the preschooler’s dress with a loud slurp. His whole chin, throat, and chest are soaked with his own spit, as is the entire area between the fox girl’s chubby thighs and the play mat underneath. Her pussy lips are swollen and an even deeper rosier hue now due to her babyish excitement, the tot panting on the mat as she chews hard on her pacifier, seeing stars. Trying to keep up the ruse still, the teacher in his twenties picks up the cylinder block and holds it up for the panting Ava to see:”L-let’s try… huff… let’s try and put it in your circle now, sweetie.”

Without waiting for a reaction, the horny bunny male nearly deep throats the block and adds to the layer of spit by squeezing his shaft and making thick globs of precum spill out of his juicy mushroom-shaped cock head onto the object, further lubricating it in his natural juices. He then holds the block steady with one hand and Ava’s swollen slit open with the other, her blue dress laid back onto her tummy as the tot isn’t even aware of what is coming.

Slowly, Lucian rotates the blunt edge of the cylinder block in between Ava’s cunny lips, parting the pudgy soft pillows as he transfers the lubricants from both sources to each other and intermingles them. Then he gently but firmly pushes, the blunt edge of the toy forming the biggest obstacle as Ava’s hips suddenly jolt, a coo and whimper emerging from her muzzle as she bits down onto her binky:”Ohww.”
The rabbit’s penis fires another volley of precum all over his own hands and Ava’s groin, the teacher hushing the four-year-old fox girl with his soothing words as he pushes the block slowly but firmly inside her tiny slit:”Such a good girl, Ava! You’re learning shapes so well today! Good girl!”

Ava’s swollen pussy lips become taut and stretched around the invading colourful toy block, the preschooler’s legs kicking in protest as her little fingers dart between them to feel her teacher’s hand and the block, trying to push against them:”Oww. Cunny full! Cunny full! Ow ow.”
Lucian lays himself down next to Ava and pulls out her binky with his teeth, spewing the pacifier away before placing his own lips over the preschooler’s and locking her in a deeply intimate kiss, hushing her protests. He can feel her little body spasm under his weight, her little fingers still feeling around and occasionally pushing against his hand and the block he’s holding, making him adjust the speed of penetration. Finally, he can feel the block has reached the limit of how deeply it can slide inside the vagina of the four-year-old, and he holds it still as he continues to french kiss the preschool girl. Lucian’s cock is firing away spurt after spurt of precum, coating Ava’s thighs as it lays along the length of the vixen’s leg, the amounts so plentiful one could easily mistake it for a low-volume ejaculation.

As Lucian withdraws the block in the four-year-old fox girl’s pussy, her body relaxes and his tongue swirls more deeply and intimately around Ava’s, the adult forcing the kiss to last for minutes. Each inwards thrust of the toy block causes Ava to stir and grow rigid, her mumbling and whimpering muffled by her teacher’s mouth, before her body grows limp and relaxed again when the bunny withdraws.

Finally, Lucian can’t hold back any longer and he withdraws the block for a final time, leaving the preschooler’s rosy swollen cunny throbbing and gaping as he withdraws from the kiss:”Very good job, Ava. You’re doing so well. Can you be a brave little girl for teacher now?”
Ava whimpers a little bit, bereft of her binky now as her teacher slowly places the fat mushroom head of his penis to her gaping entrance, rubbing her eyes as her body is wracked with so much pleasure she’s never known.

Getting back onto his feet, Lucian hunches over the tiny girl underneath him, supporting himself with one hand whilst the other guides his cock to give sticky little smooches all over and in between those soft pillowy preschooler pussy lips. He moves the spongy head of his penis back and forth all through the cleft of the still-gaping cunny hole, gently spurting and applying even more precum to lube the vixen up for his inevitable entry. Lucian takes his time, seating the warm head of his cock just inside Ava’s four-year-old pussy, revelling in the heat of her furnace-like slit, before drawing it back out again and sliding it wetly and slickly through her sticky cleft. Ava starts cooing and struggling uncontrollably once more, especially when the buck-toothed bunny intensively rubs his spongy head all over her tiny pleasure nub, her clitty pulsing and overwhelming her very young body with pleasure.

And then, the creamy brown rabbit male resolutely places the slick pink head of his penis to the slowly shrinking gape of Ava’s young pussy, and firmly pushes inside. The sensation of her head enveloping not only his head but also his shaft inch by inch makes the lop bunny’s tail tremble in delight, beads of perspiration running through the short coarse fur on his chest and back as Lucian’s body and mind are heavily taxed by the intense love making. Slowly, more of the adult’s shaft follows the path forcibly carved out by the toy cylinder block, Ava’s tiny body one more growing rigid as her small cunny is invaded once more:”Oww. Cunny full!”
Lucian is too far gone and he wouldn’t be able to stop now even if he tried, simply soothing the small discomfort the girl is feeling with deep kisses and licks as he whispers sweet words of encouragement into her perky ears:”You’re doing so well, sweetie! You’re learning the cylinder so well! Just hold on for a little longer, and teacher is gonna give you a present.”

Softly, Lucian’s spongy juicy cock head digs its way down to that most sacred of little entrances in a preschooler girl’s body, bumping gently into Ava’s cervix. The mouth of the four-year-old’s little womb is bathed in jets of precum, the lop-eared bunny’s constant spritzing of his natural lubricants having helped to keep this experience from being painful to merely discomfort for the little fox girl. Discomfort that would soon be transformed in the most wonderful of pleasures, that between an adult and a cub as young as her.

Having found the entrance to the preschooler’s womb, Lucian’s whole body shudders as he holds back his orgasm with all his might, needing just that extra little bit more before he’s ready to submit to his bodily urges. The rabbit male in his twenties draws back his penis, average in size compared to another adult, but absolutely humongous compared to a four-year-old girl. Pushing forwards, Ava groans out again in both pleasure and discomfort, her teacher giving her her binky back so she can find solace in suckling on it. The male’s balls are hovering over the vixen’s buttocks, churning in their sac, as he withdraws once more and then plunges down again.

The abandoned daycare playroom is once more filled with grunts and wet slapping noises, both adult and cub not holding back as they squeal and moan with each of Lucian’s thrusts. The mouth of Ava’s womb isn’t strong enough and with each inwards thrust, it relents a little further as it starts to open up for the bulging bulbous head of the intruder. Spurts of precum start being forced through the tiny opening as Lucian forces his cock into it, Ava now moaning as the soothing warmth spreads through her tummy like a wildfire. The preschooler’s hips are instinctively meeting with her teacher’s, their bodies in sync even at such tender age and with such a large difference in age. The juicy pink head of Lucian’s cock stretches the little mouth further and further, the sphincter then finally relenting as it snaps tightly shut behind the rim of the rabbit’s spongy crown.

Lucian’s body finally relents and loses the battle, his cock head ensnared tight like a vice within the preschooler’s womb as wave after wave of hot virile rabbit semen are injected into the most sacred of spaces within a girl’s body. Space quickly runs out and copious globs of white sperm start to ooze out from their union, a third of the adult’s cock still outside the warm velvety shaft of Ava’s vaginal tunnel as it spasms and squeezes around the thick pulsing invader. The rabbit’s perineum is flexing with each spurt, his balls drawn up tight, and the play mat underneath them soaked in his masculine juices.

Slowly, the rabbit recovers from his bliss, finding Ava whimpering and murmuring underneath him as he slowly withdraws his cock from her swollen slit. Streams of semen continue to ooze up from her pussy, and Lucian quickly pulls out Ava’s binky from her mouth before plugging it into her ‘mouth down south’, holding his sperm firmly locked within her body. Ava starts to whimper more and simply says:”I’m hungry.”
Luckily, Lucian has the solution as he makes himself comfortable on the mat in a cross-legged pose and lays Ava in the created natural cradle, offering her his penis which she immediately starts to suckle as she closes her eyes in exhaustion.

Lucian looks at the clock on the wall and realises Ava’s mother would be there within half an hour, gently stroking the white fox girl’s head as she slurps contentedly on his cum still oozing up from his shaft:”Well, I suppose you won’t forget the cylinder shape, sweetie. We’re gonna keep practicing and you’ll be all caught up before you know it!”
