ExtinctSheep commission: Of Mice and More

It’s been a good year since Dylan, or Cherri as he prefers to be called, performed his first breeding at the Facility and impregnated a very lovely and sweet dragon woman named Yrstraza. The then-ten-year-old white mouse boy’s seed had successfully fertilised the client’s egg and several months ago the Facility had reached out to Cherri and his parents. Though obviously Cherri couldn’t see the pictures the breeding organisation had sent, his parents described the cutest little baby dragon from the photos, a little boy. It had been a magical moment to Cherri, who kept touching and feeling the imprint of a little clawed baby foot in his first ever Facility award for a good long while as he was being hugged by mom and proudly patted on the shoulder by his dad. He wouldn’t be receiving such an award or pictures for every baby he helps conceive, but the Facility seems to know the first is special and thus they had sent him a little care-package, like they do with all the new breeding mice under their care.

Now, a good year after his first breeding, Cherri is somewhat of a small celebrity in the circles of the Facility as his seed is so virile it is guaranteed to successfully impregnate any woman on their first session together. On top of that Cherri has the stamina to carry on for longer than even most adults would be able to, able to take care of multiple clients in one session. Where other males could ejaculate one, perhaps two loads during their breeding sessions, Cherri could easily reach six and sometimes more. Thanks to possessing such virility even now at elven years old, Cherri can work two sessions a week, whilst other males are limited to one and then have the rest of the week off on contractually obligated sexual rest.

Thanks to being so requested and his good genes, Cherri’s self-confidence has grown drastically this past year, and thus his ability to please the client with a magical moment they are not soon to forget has grown with it. And so the Facility explores even more and newer ways to utilise the white mouse boy to his full potential, scheduling his first ever multi-session. Before Cherri had always been alone with each client, sometimes their husband would be present to be part of the magical moment their wife would be impregnated, but now the Facility has decided to try a formula with several women present at the same time. Both to save time and space so that other rooms can be utilised by other breeding pairs. And on top of that, Cherri’s father will also be participating as the fertility organisation wants to experiment with the possibly positive effects related donors could have on the chances of successful fertilisation and receptiveness of the clients’ eggs.

On the morning of the day of the multi-session, Cherri finds himself preparing himself in the bathroom at home. He’s fresh out of the shower and is towelling off as suddenly the door opens, the eleven-year-old white mouse boy twitching his nose and ears as he waits to hear who it is. The voice of his dad speaks up and chuckles, a large hand patting Cherri on his shoulder:”It’s me, bud. Just gonna hop in the shower too.”
The mouse preteen nods and smiles as he faces in the direction from where his father spoke, continuing to towel off as he hears the adult white mouse turn on the shower again:”We need to be nice and clean for the ladies. Don’t we, dad?”
Again Cherri hears his father chuckle and suddenly he can feel strong arms embrace him, pulling the smaller boy into the adult’s frame in a fatherly hug:”That’s right, son. These ladies deserve the best of the best. So brush your teeth, clean behind your ears, and soap up those big balls of yours as soon you’ll be pumping baby after baby from that big dick of yours.”
With an affectionate squeeze, Cherri’s dad fondles his son’s sac and penis, causing it to stir after half a week of no sexual action, before the adult mouse withdraws and steps into the shower.

Cherri blushes slightly, not because of embarrassment as his family had always been intimate and close to each other, but because being touched by his mom or dad still causes butterflies to flutter in his tummy after all these years. He’s always loved them deeply, and they’ve always made him feel so very loved. On top of that, ever since Cherri has started working for the Facility like his dad, his father had been speaking to him more like another man and not just a boy, more like an equal. This makes the preteen mouse so very happy and proud of himself.

The two males dress up in casual but easily removable clothing and the mother drives them over to the Facility. She kisses her two men goodbye, realising that today is a special day for the both of them, and wishes them a good time before driving off once more. Cherri taps his cane to the parking bumps along the hedges of the parking lot and is immediately able to orientate himself, having worked out the environment during his many previous visits. His father just walks next to his son, not saying anything but Cherri has long since being a young child worked out to recognise moods of people by the way they get around. The steps of his dad are light and bouncy, indicating he’s in a good mood and eager to get to work. Cherri grins as he feels just the same way, and eager to perform a breeding session in his dad’s presence.
- “What are you smiling about like a goof, bud?”
The white preteen mouse walks into his dad and embraces him from the side, which is responded to in kind from the adult mouse:”I don’t know. Just happy, I suppose. And excited!”
Dad chuckles and hugs his kid for a few moments longer:”I’m happy too, bud. And proud and excited too!”

Father and son are warmly greeted at the reception desk, many in the company knowing Cherri’s dad but the young mouse boy is quickly starting to outshine his old man, something dad is perfectly fine with and proud of. The carpet underneath their feet soon changes into smooth tiles, the ticking of Cherri’s cane to the lower parts of the walls audible every now and then as the boy counts his steps. With great precision, he finds the elevator and presses the button for the floor they’re assigned to today, the doctor escorting them making some small talk with his dad as they travel.

The changing booth is warm and comfortable, as Cherri undresses next to his dad. His sensitive nose picks up the odour of the soap his father used at home, as well as his after shave, and whereas one year ago he had been clutching his tail in nervousness the little preteen mouse boy is now erect and eagerly waiting at the door. When Cherri’s dad joins his son, he can feel the boy’s fingers briefly run over his butt cheek where the blue male fertility symbol has been tattooed onto the adult’s body. He responds in kind, touching the symbol tattooed on his son’s buttock, acknowledging him as a colleague, an equal:”Ready, son?”
Cherri nods, thrusting his hips forward and pointing to his already pulsing erect cock which has grown to five inches since last year:”Uhu, dad. Loaded and ready to go!”
Again some chuckling is audible from dad as he pats his son on the shoulder, opening the door:”That’s my boy!”

The floor underneath their feet is soft and fuzzy, Cherri recognising the thick carpet used in the breeding rooms as he wiggles his feet around in it. To his knowledge, the rooms are always pretty dark with just some dimmed lighting to make it less awkward for the clients and somewhat more of a sensual process, the blind mouse boy wouldn’t know if he hadn’t been told this fact.

Immediately upon their entering, he can hear his father’s deep voice call out next to him:”Good morning, ladies.”
Several feminine voices, some deeper than others, respond in kind as Cherri too raises up his hand and waves into the direction of the sound:”H-hey!”
Dad has placed both his hands on top of his son’s shoulders, standing somewhat behind the boy as he pushes him slightly forward:”This is my son, Cherri. I’m sure you’ve all heard about him and his talents!”
Some soft chuckling and giggling is audible close-by in the room, Cherri’s tummy wild with butterflies as he eagerly pushes his hips forward to show off his trembling preteen erection, his father continuing:”As you can see, my son has a very nice big penis and he’s quite ready. Who of you lovely ladies would like to go first with him?”
Nearly in unison, several women speak up, Cherri’s heart pounding proudly in his chest as they all seem to want him very much, the white mouse boy squirming a bit in place.

Dad chuckles and gently guides his son over to one of the women, gently patting his butt as he releases him:”I’m gonna be just over there, Cherri. Daddy’s here if you need help, although I’m sure you’ll be more than fine. But daddy’s watching, okay?”
Cherri nods excitedly, the knowledge his father is gonna have sex next to him and watch him thrilling the eleven-year-old blind white mouse boy greatly:”Uhuh. Thanks, dad. Have fun!”
Cherri reaches out and places his small hand on his father’s lower stomach, briefly sliding down to give the already semi-erect penis of his dad a gentle squeeze before the young mouse feels a set of other hands guide him forward, “Well hello there, handsome. How old are you?”
The preteen mouse boy walks over to the woman and his chest swells in pride as he grins:”Eleven!”
- “My, such a big boy already! Come let momma Gloria take care of you!”

Cherri can feel two rather large hands guide his own to the woman’s body, which seems to have a naked tough leathery skin and a full round figure to it. Cherri always loves to guess the species of the women he’s with by exploring them all over, something that has generally been received as endearing in the past. The young white mouse boy roams his hands as the woman and he crawl onto a bed, Cherri in between her raised knees as he slides his fingers down in between her legs. He can hear her coo and moan as his digits explore the tough skin and settle on two much softer pillow-like protrusions which he instantly recognises as her vaginal lips:”You feel beautiful, miss Gloria.”
The fact that Cherri always calls his breeding partners ‘miss’ is another detail that makes him so very endearing to most of his clientele, as well as his innocent child-like honesty, “Thank you, sweetie.”

The eleven-year-old blind mouse boy bites his lip as he concentrates on exploring the creases and folds of the chubby woman’s loins as he actually feels the heat radiating from her pussy increasing as he does. He can hear another woman moan not too far away from his side, his father speaking softly which seems to make his insemination partner giggle. Cherri grins uncontrollably, wanting to make his dad proud and thus he crawls up in between Gloria’s legs as he smoothly places the tip of his pink uncut humanoid penis in between her folds, gasping at the furnace-like heat engulfing his sensitive cock head:”Oh! Ah! Mm. Are you a rhinoceros, miss Gloria?”
The white mouse preteen can feel Gloria’s hand reach in between them and give his youthful 5 inch member a playful squeeze before pulling him further inside of her, “Mm, close but wrong, honey. I’m a hippopotamus. Now let’s make me some beautiful hippo babies, stud!”

Cherri moans out as Gloria’s sweltering hot and wet velvety pussy welcomes his preteen cock by sucking it deeply inside of it, squeezing his shaft like a tight vice. The white mouse boy’s pink hands are placed on the large pillowy breasts of the hippo woman, his fingers massaging the swollen nubs of her large nipples as his hips start bucking on their own. A little further away, the boy’s father is rhythmically fucking his own bed partner, making the woman cry out in pleasure as she audible clutches the sheets and moans with every wet slap of the adult mouse’s ball sac hitting her buttocks. It is music to Cherri’s ears, the young preteen boy trying to time his own thrusts with his dad’s and imagining they were fucking these women truly side by side with their thighs and knees touching. Cherri knows he does a good job at the Facility, but to be able to prove this to his father in person makes him both excited and nervous at the same time, craving his parents’ approval like every child does.

As Cherri nearly reaches his first orgasm, clawing at Gloria’s thick nipples and groaning deeply, the hippo lady speaks up:”Look, dad. Your son is gonna cream my pussy good and give me a beautiful baby!”
The blind mouse boy can hear his father slowing down for a second, speaking up:”That’s my boy! I’m close too, champ. Wanna cum together?”
Cherri nods eagerly, grinning from ear to ear as the soft and wet hippo vagina slurps away at his sensitive penis, his youthful sac drawing up against his small body as he pants:”Y-yes, daddy!”
- “Alright, here we go then. On the count of three. One, two, … Three!”

As his father counts down, Cherri slams his hips into Gloria’s large pussy and hears his dad’s hips do the same to his own bed partner, both women cooing and moaning out as father and son release their hot seed deep within their loins:”Ngh, daddy! I’m cumming, daddy!”
Dad growls deeply, clearly pumping a healthy load of studly semen inside his partner’s womb as he reaches over and gently strokes his son over his back before his hand settles on Cherri’s bubble butt:”Atta boy, son! That looks so sexy! Good job!”
The women seem to concur as they moan and their hands roam over the bodies of their studs, Cherri’s hand suddenly picked up by the woman his dad was breeding and placed between her legs as dad withdraws his penis:”Your dad did a good job too, handsome. Feel that?”
Cherri’s fingers are slipped inside of her heated sex, now slick with his father’s seed as he can feel the thick gooey texture of the slimy substance now coating his digits:”Uhuh. One day I’m gonna have loads as big as my daddy!”
The strange woman’s legs squeeze the blind mouse boy’s wrist in a vice-like grip in response, as does Gloria’s hippo pussy around Cherri’s cock before it is ejected out by sheer force of pressure, both ladies clearly loving the father-son dynamic that’s going on.

Cherri doesn’t get a moment to rest, though, as immediately strong clawed hands reach around his slender waist and make the mouse boy squeal as he’s lifted into the air. To a blind mouse like he, that takes away one of the senses he needs to orient himself, thus making Cherri briefly feel truly blind before he’s planted on top of another very large woman, “Hello there, sweetie. Now it’s my turn. Mates are hard to find for a species like I am, so please make me several beautiful babies.”
The preteen boy’s hands orient themselves as he explores the tall woman’s features, finding a scaly hide and a set of impressive tits between which he immediately snuggles his whole head:”O-okay, miss…?”
- “Call me Tina, dear. You looked so impressive impregnating Gloria! Would you mind if I help you back up?”

Cherri is briefly puzzled and to his surprise lifted back up in the air again, his whole lower body suddenly engulfed by a huge mouth as he lets out a terrified squeak. His hands clutch the scaly rough nose as he can feel the broad slimy tongue of the woman bathe and swirl his whole lower body in her saliva, dragging itself up between his legs and stimulating his balls and semi-erect eleven-year-old penis:”Ah, dad! Help!”
The frightened mouse boy can suddenly feel his dad hug his upper body from behind, a soft laugh to his voice as he calms his boy:”Don’t worry, Cherri. No one would harm you here. It’s just a very unique experience, isn’t it? Tina is so big she can literally give a blowjob to your whole lower body!”
Cherri’s hands claw some more at Tina’s nose as fear turns into pleasure, his whole lower body being wrapped in a warm and slick prehensile blanket as the huge woman’s tongue swirls around him and she sucks onto him as if he were a candy cane. He calms down and leans back into his dad, who pats him on the head:”Is Tina a dinosaur, dad?”
Cherri can feel a deep approving rumble all around his body, his balls and body being massaged by the large vibrating wet tongue as dad speaks up:”Good guess, son! Tina’s a t-rex. Their species is nearly extinct so they really need omni-breeding males like us to survive!”

After a few more minutes of gentle sucking on Cherri’s lower body, the boy cooing and moaning in his father’s arms as the adult mouse continues to pet and praise his little boy, Tina releases the boy and dad quickly helps slide his son to her quivering large cloacal slit. As Cherri’s boyish cock slips smoothly inside the very large opening, he coos as he senses the cool temperature within, realising Tina is cold-blooded which is another exotic experience to a mammal like him:”Ooh, you feel so good inside, miss Tina.”
A deep chuckle rumbles through the huge woman’s chest as Cherri can suddenly feel her large arms reach around and past him, picking something or someone up behind him as the mouse boy can suddenly hear his father squeak in surprise too. The next second, Cherri his hugged tightly from behind by his dad, the adult mouse’s penis stiffening again and wedged between his son’s buns, “What do you say, dad? Feel like helping your son fill this deep need inside of me?”

Dad chuckles as he presses into his son for a moment, embracing his little boy which makes Cherri feel even warmer inside than he already does, before pressing his cock down into the large slit between his legs:”Always happy to oblige a lovely lady like yourself, Tina!”
The t-rex moans out as a second cock now fills her cloaca, Cherri gasping as he can feel his father’s penis rub back and forth along the underside of his own as they move back and forth in a different rhythm, causing their rods to create even more friction against one another. Dad’s arms are now firmly embracing his son’s slender small frame, hunching into the slick pussy below and moving his body as if he were fucking his son, leaning his face down next to Cherri’s and giving his boy a kiss or two as he breathes hot air into the eleven-year-old’s neck. He softly whispers as he reaches down and gives the base of his son’s cock a squeeze whilst Cherri is still fucking the gigantic reptile:”Pretty hot, huh? Son? You’re such a fucking stud already, son. I’m proud of you. So very proud!”
Dad emphasises those last words with each thrust of his cock against his son’s penis inside the huge cloaca, causing the small mouse boy to grunt and moan as he shivers all over and uncontrollably starts releasing his seed inside Tina:”Ngh, oh. Daddy!”

Cherri’s father grins wickedly as he holds his son, continuing to pump his own hips as he allows his boy to ride out his earth-shattering orgasm. Tina moans out too, her huge body shivering and shuddering as her large arms encircle both father and son, hugging them to herself so that her huge tits smother them both:”Oh, yes! Son is blasting off! Come on, dad. Put a baby inside of me together with your boy!”
Sure enough, Tina’s encouragement is what tips dad over the edge, the adult mouse groaning and crying out as he hugs Cherri tightly to his chest, the preteen cub in heaven as he’s smushed between the t-rex woman’s large tits and his father’s chest. Hot semen are spurted all over the underside of Cherri’s sensitive penis, the eleven-year-old’s cock continuing to shoot even more sperm when realising his father’s virile seed is dripping down from his balls all the way to his helmet inside the slit.

Cherri’s cock is hard as steel when it is pulled from Tina’s slit, spraying the last drops of watery boy-sperm over her magnificent tits as she hugs the cub and his dad to her body, “Thank you both so very much!”
The mouse boy grins and snuggles into the large woman:”Glad to help, miss Tina. Hope you’ll have many beautiful babies!”

Cherri and his dad dismount the huge reptile woman and take a breather, the boy’s penis still erect and not giving any signs of fatigue whilst dad’s is semi-erect at best. Gloria, Tina, and the third woman make father and son kneel in front of each other and compare both cocks by holding them alongside each other, impressed with Cherri’s growth progress and commenting that he’s gonna be bigger than his dad someday, which makes the preteen boy’s chest swell with pride. Dad pats his son on the back and indicates that two releases is all he’ll be able to do, but for Cherri to take care of the last client.

Large clawed paws gently take hold of Cherri’s small hands and lead him forward, the boy taking his time to explore the woman’s furry body and gravitating towards her chest to squeeze her voluptuous breasts. The boy suckles the sensitive nubs, causing his partner to shudder and cradle him in her arms as if he were a baby. Cherri has always loved to nurse from anything and anyone who would allow him to, it seems to fill his body with a natural happiness and joy. He quickly guesses correctly that she is a bear, making some small talk as she introduces herself as Rebecca. Gloria and Tina were wonderful, but Cherri finds that he prefers the furry species, since he’s able to snuggle all nice and warm into them as he would slip his penis into their slick hot wet slits and pump away whilst being so cosy and comfortable. So too he mounts Rebecca and continues to suckle and lap at the big nubs of her teats, feeling her clawed paws roam the back of his body and every so often squeeze his bubble butt and tease the pucker underneath his tail, to his giggling delight. He can faintly hear his father chatting with the three other women, mostly about Cherri and how he got started into this business at such a young age.

Every thrust is rewarded with a deep approving rumble from Rebecca’s chest, the bear woman stroking Cherri’s back and head as if he were her own cub and they were just snuggling:”Mm, you seem to be very close with your daddy, huh?”
Cherri nods, smiling as he continues to tease the woman’s teat with his small pink tongue:”Uhuh, he’s the best dad in the world.”
Rebecca seems to sigh happily, squeezing Cherri into her as if wanting to press more of the boy’s abdomen inside her slick sex:”I hope my future cubs will grow up to enjoy such a bond with me and their dad too. I want nothing but the best for them, so I’m very happy you’ll be the one planting them within my womb, Cherri!”
Cherri grins and nods, his milky white eyes turning up as his lips find Rebecca’s and the surprised bear tenderly responds by kissing the eleven-year-old mouse boy, gently pressing a finger inside of his cute little butt and causing the cub to ejaculate with a long deep moan. Rebecca’s pussy lips are all swollen and slick with their combined juices, the warm sheathe suckling and slurping all over the preteen cub’s shaft as he withdraws his penis from between her thighs.

Cherri can feel his lower body sticky with saliva, semen, and pussy juices, indicating he needs to freshen up as he and his dad say goodbye to their clients and head over to the spa within the Facility to rest up and head home. They have a lot to discuss and many happy memories to process, hoping that the Facility will decide to allow them to perform together more often.
