SenGrisane commission: When Daddy’s Not Home

The house is quiet and peaceful, the afternoon sun shining through the windows and warming the cosy interior. The residence reflects a lower middle class income but looks warm and inviting nonetheless. On the floor of the living room sits a young donkey boy named Sen, holding the controller of his games console as he bites his tongue in concentration. His gaze is fixed upon the rather small television screen, the bulbous glass protruding from its frame and humming a soft buzzing sound like CRT technology tends to do. Sen is about six years old, has light grey fur with darker spots on his bum and a cute tuft of blond hair on his head and at the tip of his tail. The donkey cub is only wearing a white tank top and undies, today being a Saturday and he’s free to stay inside and play his games.

Finally Sen puts down his controller and turns off the console, the television screen growing dark as he sits up and perks his elongated donkey ears. Daddy is out working and mommy is resting in their bedroom, she had asked for Sen to play quietly until she got up to make dinner. He shifts a little in his seat and sighs as he looks around and listens to the silence. Sen wanted to invite a friend over but his mom doesn’t really like that when his dad has the weekend shift. Says it’s exhausting watching over two rowdy kids alone.

A sudden growl in his tummy makes the little donkey kid groan out, getting up from the couch and climbing the stairs towards his parents’ bedroom.

The upstairs is even quieter than downstairs, the silence dense in the air like a blanket as Sen’s ears instinctively flop down his neck, as if he’s not supposed to be there. He tiptoes over to the bedroom door and peeks in. The curtains are halfway drawn and thus only allow a single strip of light to illuminate the foot-end of the bed. Resting under the thin blanket is his mother’s form, her chest slowly going up and down with her breathing, her bosom only covered by a thin pink frilly undershirt.

Sen pushes the door open and softly walks over to his mom’s side of the bed, the thick carpet muffling the sounds his hooves would make on the floor. The little six years old donkey boy’s eyes move over his mother’s frame, taking in how beautiful she looks whilst she rests so peacefully. He’d already promised her that he’d marry her when he’s all grown up. She had laughed and asked him:”What about daddy?”
He had just smiled back at her smiling face and said he’d marry him too, so they could share her as their wife. Mom had just shaken her head at her son’s silliness with a smile, tucked him in and kissed him goodnight as a response.

Gently, Sen shakes his mother’s shoulder, whispering quietly:”Mommy?”
Humming whilst still half asleep, the woman acknowledges her son’s presence:”Mm, yes, dear?”
- “Mommy, I’m hungry.”
Without opening her eyes, Sen’s mom turns onto her side to face her son, drawing back the blankets to invite her little boy into the bed with her. Sen smiles and hurries to crawl up next to his mother, snuggling himself in a cosy position as his little hands grasp her firm breasts through her clothes. A mother would have been expected to scold their son for touching her so inappropriately, but Sen’s mom just smiles as she rests with her eyes closed, drawing up her pink undershirt to reveal her furry full bosom with perky pink nipples. Without hesitating, the little six-year-old leans in and encircles one of the large teats with his lips, starting to suckle as a stream of creamy rich milk spurts against his tongue.

The donkey woman has been breastfeeding her son since his birth and thus her breasts keep producing milk for Sen and his dad to enjoy. She smiles and hums, her eyes still closed as she enjoys the closeness and sensation of her little boy’s tongue lapping and circling around her sensitive big nipple. Sen’s mom pulls her son closer into her, rubbing his back through the white tank top and moaning softly:”That’s my good little boy, mommy loves you very much.”
Sen feels butterflies twirl through his young stomach, smiling around his mom’s nipple as he briefly draws back to mumble:”I love you too, mommy. You’re the best mommy in the world!”
Sen’s mom smiles and strokes her son’s blond hair, rubbing her thighs together a little as her little boy’s suckling elicits those pleasurable tingles down inside her loins.

Sen keeps suckling for a while, filling his tummy with his mommy’s delicious cream as he switches breasts when the first starts to run a little dry. His mom has repositioned herself slightly, drawing her son on top of her and between her legs as she now lies on her back. She can feel her little boy’s excitement stand firm inside his little undies, rubbing against her hot nether region:”Mm, my darling little Sen.”
The six years old donkey boy releases his mother’s teat from his lips once again as he meekly asks:”Mommy, why is daddy away so much?”

Mom just strokes her little boy’s hair as she rocks him back and forth over her stomach:”Mm, daddy works weird hours so he can bring in some extra money, sweetheart. And so mommy can stay home more often to take care of you and the house. He’s always here when it matters, no?”
Sen pouts a little, rubbing his cheek against his mother’s full breast as he pinches the nipple absentmindedly, eliciting another moan from the donkey woman’s lips:”Mm.”
Mom looks over at the clock radio on her night stand, directing Sen’s gaze towards it:”See those first two numbers? Can you add two more to them?”
The little donkey boy bites his lip and squints his eyes in effort when finally he blurts out:”Eight-eighteen?”
- “Very good, sweetheart. When those numbers become eighteen your daddy comes home today. He works very hard for us so maybe we should prepare a little surprise for him, eh?”
Sen smiles and nods enthusiastically, knowing exactly what mommy means when she wants to surprise daddy.

The donkey woman pulls off her pink night shirt, shaking her blond curls back and forth as Sen now kneels down between her legs on the bed, looking up expectantly at his mother. She’s always been the most beautiful woman in the world in his eyes, the perfect mother figure. Sen’s mom smiles and points at the little six-year-old’s tenting white undies, flicking it playfully which makes her son giggle:”Seems someone’s ready for some cuddling, eh? Sweetheart?”
Again Sen nods enthusiastically as he lunged forward and embraces his mommy tightly, nuzzling his nose in between her firm breasts and grinding his little boy boner into her stomach:”Uhu! I love you, mommy!”
Mom murmurs that she loves Sen too as she presses her nose in his soft blond hair, grasping her boy’s tight little buttocks through his white undies, kneading them and giving them a playful little slap.

Sen giggles and wriggles around in his mother’s arms, nuzzling his face into her bosom some more, feeling his mommy’s hand slip into the back of his undies and gently rubbing his bare butt. She whispers into his cute little ears:”My wonderful little boy.”
Sen squeals happily, gasping out and his small frame stiffening when he feels his mommy’s finger suddenly dip underneath his tail, massaging his pucker:”Oh, mommy…”
Mom softly grinds her hips against her son, gently rubbing her little boy’s anus without actual penetration yet, feeling his little boner rub against her loins:”Mm, why don’t we take off these clothes, sweetheart?”

Like the excited little boy that he is, Sen jumps up and back onto his knees between his mother’s legs, grinning widely as he quickly pulls off his white tank top and undies. Meanwhile, Sen’s mom lifts up her legs semi-seductively, winking at her blushing little boy as she slowly draws her panties up and off her legs, tossing it on the floor next to the bed:”Now, doesn’t that feel much nicer?”
Again, Sen nods profusely, his cute little donkey penis standing stiff at attention as it points directly at his mommy, pulsing with each beat of his heart. Black in colour with white spots along the shaft, the equine member pulses up and down, eager for mommy’s touch. Underneath the erect little penis hangs his small sac, not that big yet but a delight to play with for both mommy and daddy.

Mom opens her legs as she splays them wide for her son to gaze upon her sex, the little boy frozen in time as his wide eyes and open mouth attest to his immature desire. The donkey woman smiles at her little boy, wiping the blonde curls from before her eyes and behind her ear as she then dips down both her hands to her nether region. Ever so gently she parts her lips, a hint of pink opening up into a deeper hue as her love tunnel is laid bare for her son’s eyes to see:”Do you think mommy is beautiful, sweetheart?”
Sen is unable to speak, his eyes glued to his mother’s blossoming flower as he just gulps and nods, scooting a little closer and touching his mommy’s thigh. Electricity runs from his innocent touch all the way up his mother’s spine, making her shudder in delight as Sen continues to stare at her beautiful pussy.

The donkey woman just smiles encouragingly to her son, gently massaging the sensitive nub at the top of her opening, whispering huskily:”Wanna help mommy feel good?”
She doesn’t need to make her invitation any clearer, her little boy grinning and nodding as he lays himself down on his tummy on the bed, replacing his mother’s hands with his own smaller ones to keep his mommy’s lips parted. Sen’s face scoots closer and small pink tongue darts out, quickly tracing from the bottom of his mommy’s vagina all the way up to her sensitive clitoris. Mom’s head falls back into the cushions, the woman not needing to give her son any direction as he has done this many times before. From the day Sen was born, both his loving parents bestowed him with attention and their best parenting skills, learning him to approach the world with an open mind.

The bedroom is filled with cute little mewls and gasps from both mother and son, Sen doing his best to please his mommy as he lavishes delight upon her sex. His nose is firmly pressed into her pleasure button, his small hands holding on to her hips as he mouth is sealed to her pussy lips, probing his tongue inside as if he was digging with it. The six-year-old can’t help but grind into the bed underneath, his penis too young to produce any pre-cum or sperm yet but already very familiar with the pleasures of sex. Sen’s mom thrashes around a little as her little boy sucks and probes her depths, clutching her legs shut around his head every now and then as she grasps at the blankets and her son’s hair.

She loses it as soon as she feels her son’s tiny finger suddenly wriggle itself inside of her love tunnel alongside his tongue, stretching her a little and curiously exploring her depths. Mom moans and presses her legs together, trapping her son’s small head between and grinding her pussy against his face, crying out as she keeps Sen firmly in place.

Sen knows his mommy is experiencing one of those ‘or-gash-ums’, his parents having explained this phenomenon to him. He has even experienced some of his own, though of course without the release of semen like his daddy does when he has his climax. The little boy hums inside of his mother’s folds, knowing that she likes the vibrations whilst she rides out her orgasm, gently releasing the grip on his head more and more as she calms down. Mom lies back into the sheets, panting, as Sen sits up on his knees again. He smiles at her with a wide grin, his muzzle positively wet with her juices as he asks innocently:”Did you like that, mommy?”

Mom grins, temporarily exhausted as she pulls her little boy on top of her, cuddling him into her body and breasts as she strokes his bare back:”Mommy loved that, my sweetheart! You did such a good job making mommy feel good.”
Sen almost purrs like a kitten at the praise, his little penis twitching as it has become nestled against his mother’s hot and wet sex. The six years old boy subconsciously bucks his hips a little, the tapered tip of his youthful equine black penis tapping against his mother’s love entrance, becoming sticky with her wetness. The adult donkey woman doesn’t stop her son, welcoming his rock-hard proof of admiration for her, gently shifting her loins around underneath him until finally his tip finds its mark. She grabs Sen’s bare buttocks and gently pulls him towards her, the donkey boy squeaking out in uncontrollable pleasure when his mother’s vagina welcomes his penis like a warm wet velvety glove cradling it.

A loud groan escapes Sen’s lips, his cheek mushed into his mother’s firm breast as its teat pokes into his closed eyelids:”Ngh, m-mommy…”
Mom strokes her little boy’s hair, closing her eyes as well as she feels her son’s short length slowly slide all the way inside of her:”Mm, feels good, doesn’t it? Sweetheart?”
Vague movement indicating nods can be felt against her breast, the little boy’s body taking over control from the mind as Sen instinctively starts pushing his penis in and out of his mother’s hot crevice. The donkey woman starts to push back against her son’s thrusts, moving in his rhythm as his equine cock is still large enough to give her a great deal of pleasure. If only her husband were home to enjoy the closeness of his family as well. Soon, though.

Sen’s mother reaches down over her son’s back again as he humps into her with his youthful enthusiasm, faster and faster as if he was participating in a race. Her finger circles around the base of her son’s tail before dipping underneath once more, giving her boy’s pucker a testing poke. The six-year-old moans out against his mommy’s teat, closing his lips around the nub as he draws forth the last of her milk. The adult woman brings her finger to her mouth, giving it a good coating of spittle before once more reaching for her little boy’s ass hole, gently pressing and rotating the digit’s tip inside.

Slowly mom’s finger massages and rotates itself deeper and deeper into Sen’s tight butt, the little boy moaning and grinding into his mommy faster. His small body shudders when suddenly the tip of the digit bumps into his immature prostate, Sen gasping out and his little cock giving a jerk inside his mommy’s depths at the sudden jolt of extreme pleasure. Mom smiles and grasps her son’s shoulders to keep him in place, pressing and swirling her finger around her little boy’s internal pleasure nub, Sen thrashing in her arms and moaning loudly. His involuntary bodily movements cause his youthful penis to be pushed even deeper inside of her, mom closing her eyes and moaning into Sen’s long floppy donkey ears whilst her finger relentlessly stimulates his prostate.

- “Ungh, ungh. Mommy! Mommy, it feels… I’m gonna…”
Mom grabs her little boy even tighter, hushing him as she can feel Sen grow rigid all over and his anus clenches tight around her finger. His small equine penis throbs inside of her love sheath, attempting to spurt forth non-existent jets of sperm to impregnate the fertile female it’s nestled in. The adult donkey woman clenches her legs around her son’s small hips, closing her eyes as another orgasm waves over her, her vagina rippling and squeezing around her son’s cock to milk forth the sperm that wouldn’t spurt inside of her for several more years.

Soon the two calm down again, Sen panting in his mother’s arms as she strokes his hair and back lovingly, motherly. Her womanhood still embracing the taboo union of her son’s loins inside of its depths, the youthful penis not losing hardness for a second:”Did you have fun with mommy, sweetheart?”
Sen moans out and nods, his hips giving a last subconscious thrust as his mother’s other hand lowers down to his butt as well. Gently mom hooks the tips of her index fingers inside her little boy’s entrance and she parts the tight ring, making Sen whimper in confusion, “Mommy?”
- “Just checking, sweetheart.”

Mom gently fingers her son’s anus a few minutes more before she reaches over to her nightstand, retrieving some items. Sen has recovered his energy and is now once again kneeling in between his mommy’s legs, looking over at her actions curiously. The donkey woman with the long blonde curly hair and short fuzzy ears smiles at her son naughtily, laying down a dildo of large size and a bottle of lube in front of him:”Still wanna surprise daddy? We’ll have to stretch a little more before he gets home, though.”
Sen suddenly understands his mother’s intentions, giggling as he mock pretends to overthink her proposition before jumping a little in the air off the bed:”Mmm, okay!”
Sen’s mom smiles and pats her lap, the enthusiastic little six years old donkey boy still giggling as he lays down on it, pulling his own tail to the side so his mommy has easier access.

The squirt of lube onto his hole is cold, surprising Sen a little as he gasps out, his mommy chuckling and massaging the slick liquid inside of him. She then coats the large dildo in a layer as well, gently putting the head to the boy’s entrance:”Ready, sweetheart?”
Sen nods, wiggling his butt a little as his mommy starts rotating and pushing the bulbous end against his tail hole. They’ll have plenty of time to prepare for daddy still, and they’ll need plenty of time to be able to make daddy fit inside his son smoothly and comfortably!
