After getting all the chores done for the night, Sherry and I head to the house to cook up a meal to satisfy our guests' stomachs. Once everyone is done eating, I watch my niece head toward the guest room while saying, "Ah'll make sure to wash your sheets tomorrow, so breed those horny mares well..."

Limestone sees her sister look around before looking at her with a suggestive look, understanding immediately and asks, "Where is your room located, Mister Sheridan?"

I look over at her and say, "My room is up the stairs on the left, and the bathroom is the second door on the right, should you two need to use it."

The older sister looks at Marble as she makes her way behind him and distracts him, guessing at what her sister intends to do as she lowers her head and keeps pushing forward.

I put the cleaned dishes away as the two mares nuzzle against my legs as Marble nudges her way between my legs, causing my legs to buckle and sit on her back. I look down as I hear her huff lightly and ask worriedly, "Are you alright Marble? I'm a pretty heavy burden to put on your back."

Marble looks behind her at Roger with a smile saying, "You're not hurting me because Limestone and I both work on a rock farm, do you not remember hearing that from Limestone or Pinkie maybe?"

I continue to sit on her back, feeling very awkward about sitting on the back of such a small pony and nod saying, "Ah do, ah was not quite sure how much work ya two do out there at the farm. How are ya not feeling any pain from mah weight, is it an Earth Pony thing?"

Limestone steps up behind her sister and says, "It's a bit of both. We have a mine that we go into and harvest rock when we need them, occasionally we have to replace timbers to keep the ceiling from collapsing. Here, place your hands behind my head between my neck and shoulders, then cross your legs underneath my sister's neck to keep from falling off and maintain your balance."

Feeling unsure about this I try to look back behind me and reach back with one arm, feeling for where the mare's head is, and touch something soft under my palm. Unable to see her very well, I rub the surface of the mare a little, feeling around it to try to identify what I'm touching when I feel something sticking up and very soft. Realizing it is her ear, I continue to run my hand backward along her body.

She bites her lip softly as the human's caress stokes her inner desire to breed, inadvertently letting a moan escape her as she says, "Don't stoke my fire too much or we won't make it up to your bedroom."

When my hand finds the base of her neck, I smile and say, "Sorry, ah couldn't see ya back there very well, so ah used my hands to find yer neck." then place my other hand behind me next to the other and then lift my legs, then hook them under Marble's neck as Limestone told me to.

As I feel Marble heading toward the stairs leading to my room, I tighten my legs under her neck and say, "This is the first time ah've ridden a pony so small, it feels so awkward to do this."

Limestone lifts her head a little and breathes in his scent, saying, "It feels the same way for both of us." then licks his upper arm.

Marble makes her way up the stairs, carefully lifting her hooves and setting them down. Each step she takes gets her closer to the top, finally seeing the last step a few feet away, thinking, 'I've been dreaming of this night since Pinkie told me how gifted he was.'

When we reach my room, I unhook my legs and return them to the floor, then stand on my own, saying, "Thank ya for the lift girls, but ah believe it is time for me to return the favor..."

I get down on my knees and turn to face the two mares, pulling the soft-spoken Marble to me with my left hand and angling my head to the right. Placing my lips on hers, I slowly slide my tongue against her lips until she opens her mouth for me and open my eyes to see her sister watching on curiously. Calling her forth wordlessly as my tongue starts trying to teach Marble how to kiss, I watch Limestone walk forth and slide my hand around the back of her head.

As Marble starts to get an idea of how to use her tongue, she feels him pull away and watches as he starts to kiss her sister, which makes her eyes widen a little when he slips his tongue between her slightly open mouth. Seeing an opportunity to be intimate, she moves to his neck and lightly kisses it before alternating between kissing, licking, and lightly nipping it. Making her way to his ear, she takes the lower part in between her teeth lightly and tugs on it until it pulls free. She then feels his left hand snake its way down her back and between her cheeks, slipping a part of his hand into her marehood, which earns a low, sultry moan from her as her tail lifts up and moves aside.

I quickly learn that Limestone is a fast learner as she starts to get into it, opening her mouth wider and pressing our mouths further against each other. As our teeth click against each other occasionally without a care, we wrestle each other with our tongues while I take her left ear into my hand and massage it between two fingers.

Limestone closes her eyes as she starts to softly moan into his mouth, enjoying the wrestling match going on between their tongues. Swallowing some accumulating saliva, she feels his hand slide down her back as part of it starts to play with her marehood.

As I start to smell the mare's arousal while Marble plays with my ear, I take my hands away from their rears and begin to undo my laces to take my boots off first. Once I get them off and toss them aside, I move back to kissing Marble as her sister pants moderately with need, pulling her lower lip between her teeth and lightly biting it while her tail sways from side to side.

She watches as Roger takes his pants and underclothing off, setting his semi-hard member free and capturing her attention. Curious, she lowers her head down and gives the underside a long lick, then savors the taste a moment before running her tongue along the underside and guiding it into her mouth. Treating it like a carrot they eat on rare occasions, she sucks on it and pulls her head away from the base.

Marble starts to get into the kiss as she slowly uses her forelegs to walk up his body and wraps them around his neck, pushing her tongue into his mouth while breathing through her nose. Feeling him run one hand behind her flank again, she lets out a husky moan when his other hand starts to massage her teats, making her close her eyes as she surrenders herself to her instincts.

Limestone sucks away on his member, feeling it go down and into her throat when it is at full hardness, causing her to gag a little bit and make his member a little slicker. She hears her sister start to moan when he stands back up, making her head angle up along with her neck when one of her sister's hooves bumps into her right ear. Looking up, she sees his hands holding onto her rump as her sister's marehood winks and drips eagerly, unintentionally landing on her muzzle while his member is deep in her throat. She feels him moving around, forcing her to turn her body, and feels him walk forward. With no choice but to back up, she keeps going as her sister's hooves sway and bat at her ears lightly. She runs out of room to back up as her rump presses up against the bed, feeling his member pressing further into her throat as she starts to choke.

I lean forward and lay Marble halfway onto her sister's body, then pulling my upper body back so that Limestone can breathe again. Kissing my way down Marble's throat, I continue down her chest and then her stomach when I reach her two teats. Pulling her left teat into my mouth, I roll the nipple around my tongue as I feel my tip ride along the top of Limestone's tongue and hear her take in several, much-needed breaths of air.

Marble lays on her back with her eyes closed as she hums blissfully at feeling the human suckle her flat teats, laying her front hooves on the back of his head instinctively as her gentle moans get louder.

As she feels her sister's body halfway on her, she thinks to herself, 'This stallion better not waste this load down my throat...' She is taken by surprise when he suddenly rams forward to the base, feeling his weighty sack tap the top of her throat as he then starts to pull back immediately.

Settling into a quick throat-fucking rhythm, I then push Marble ahead and start to eat her marehood out saying, "Are ya ready for some more fun Marble?"

With a gasp, she nods rapidly, saying, "Yes, yes! Pleasure me!" Then loses the ability to speak as her moans get even louder when she feels him use his mouth and teeth on her marehood, driving his tongue deep into her folds while brushing his teeth over the edge of her entrance.

Limestone somehow manages to breathe between his thrusts, her body's desire to breed as high as it's ever been. Losing track of the time, she feels her sister start to shudder and hears her plead, "W-Wait...I-I need to go! The little filly's room calls me!"

Marble battles her urge to relieve herself when she gasps and nearly loses control as Rodger wraps his strong hands around her thighs, pulling her even tighter against him as he drives her further into a corner and pants with effort, pleading, "P-Please! I-I really need to go! I must go pee!"

Locking her into place, I fight to destroy her holding back and am rewarded by a shrill squeal, shouting, "NO!" before tasting the familiar extremely bitter flavor of a mare's urine as her bladder unloads into my mouth. Relaxing my throat, I force myself to swallow it all as the mare's back arches up, lifting her front body off the edge of the bed as she pushes the fluid from her body.

Her body then goes haywire as every nerve in her body comes alive, sending her into an intense orgasm as she throws her head back and arches her back the other way while her hooves try to curl inward, crying out, "FFFUUUUUCK!!"

Limestone has difficulty breathing when his member gets even fatter inside her throat, making it a real challenge as it stretches to accommodate his girth, thinking, 'Hopefully, he remembers that I need to breathe...'

Tasting a tart fruity flavor as her nectar gushes into the back of my throat, I swallow it greedily until the mare stops shaking violently.

Marble's mind is completely blank as her nerves continue to go haywire when she is pushed further onto the bed and allowed to fall to her left side, panting heavily, saying breathlessly, "I...hah...can't...hah...believe...hah...you...hah...actually...hah...drank it. That...hah...is...hah...so...embarrassing...hah...for a...mare."

Feeling a tightness around your member, you see Limestone looking up with hazy eyes and try to pull out of her throat. Finding yourself stuck a little, you have to massage her throat a little to get it to release its hold. Coming out of her throat and mouth with a loud pop, you kneel down and kiss her deeply, saying, "You have a remarkable throat, Limestone. Take a moment to catch your breath while I breed your sister."

Limestone nods and says, "I appreciate that, but I need to go to the little filly's room. Where is it located?"

I line myself up with her sister's marehood and say over my shoulder, "It is the door just to the right of the one leading into the hall."

She softly moans in protest when she feels him start to turn her onto her back once again, gasping in delight as she feels a thick tip part her entrance and slip in. When she is on her back, she splays her back legs wide and wraps her front hooves around his neck as he leans down to kiss her. As she looks into his eyes, she says, "Please give me a foal this season..." then slips her tongue into his mouth as she feels him push deeper into her and take her cherry.

Pushing myself inside to the base as she clamps down on me and hisses in pain, I hold myself there until she relaxes and return to kiss her deeply to take her mind off the pain. When she finally relaxes with a sigh, I pull back and slowly thrust forward until she can comfortably accommodate my girth.

As Limestone finishes relieving herself, she flushes and re-enters the room to see his thick, bloody member driving into her sister completely with a wet slap. Curious, she makes her way in between his legs as he thrusts into her sister, looking up to see Marble's entrance spread wide open around him. Her sister's entrance disappears from view as a large pair of orbs brush along the fur of her face and block her view, slapping wetly against Marble's entrance and making her moan out. Wanting to be part of it, she extends her tongue out and licks his shaft when it appears, then lightly suckles his balls when they slap her in the cheek.

Marble loses herself to the pleasure as she bites onto his shoulder when she starts climbing the peak again, hooking her back legs around him as best she can, pleading, "Please, please fill me with your seed, I've been a good mare, haven't I?"

Placing my hand behind her head and gripping her mane, I smile and nod, saying, "Yes, you have been a very. good. mare. So let me give you the foal you've been craving for so long..." I then slam myself forward, hearing a surprised eep from behind me and hold myself there with a chuckle, saying, "Your sister got a little bit nosy and has become one with us."

Arching her back and screaming out in pleasure, she gushes around his member as it enters her deepest part. Not caring about her sister's nose being inside her, she lets herself get swept away with the heat of his seed, shouting, "Yes, breed this mare's pussy all night long!"

Trapped in between her sister and his groin, she feels each pulse of his throbbing member as it wildly pumps seed into her sister's waiting womb. Her tongue tastes a small bit that oozes past and into her mouth, finding it a bit salty, but favorable when she is forced to hold her breath after her sister's fluids gush out and get all over her muzzle.

Nearly losing consciousness after he pumped his seed into Marble's untouched depths, she feels herself being lifted up and looks around as her eyes refocus. Finding herself being placed on top of her sister's very swollen stomach with Marble's face lost in a daze, she then feels him wrap his hands around her throat and drive himself into her. Crying out in pain as she feels like she is being split open, she says, "Are you trying to break me in half?! Holy Celestia, you're huge!"

When I push in further, she spasms wildly as I feel her squirt all over my balls and thighs, saying, "Ah'm just doing what ya asked me to...getting ya horny mares pregnant." I then ram into her all the way and hear her let out an audible 'hurk' when I punch into her womb and hit the back wall, saying, "With how tight ya are, ah doubt either of ya will be going home tomorrow."

Unable to sleep due to the noise upstairs arousing her curiosity, Sherry makes her way to the kitchen barefoot to make herself some moon tea, saying, "There's no way ah'm gonna be laid up for nearly two years with a baby..."

After drinking her tea down and washing the cup out, she makes her way up the stairs to her uncle's room. Pushing the door open as she hears a mare cry out in ecstasy, she watches Limestone's body shake violently as she orgasms. Making her way around the bed, she watches with a smirk as the mare's abdomen begins to swell up like a balloon and starts to strip out of her clothes, asking, "Ah had a cup of moon tea, do ya have enough left for your favorite niece?"

I look over my shoulder as Limestone babbles incoherently while pumping my load deep into her body, saying, "Ah always have enough left fer mah little tree." Once I finish coming, I pry myself out of the now unconscious mare and let her slide off her sister, then turn around to face Sherry as she runs toward me.

Sherry leaps high with her strong legs and uses her quick coordination to line him up with her slick, yet slightly sticky entrance and feels him slide in. Wrapping her arms and legs around him, he is sent off balance as she says, "Like a glove...hehe."

Falling over onto my back, I say, "Ooof, it still amazes me that you can still do that and not get it in the back door."

She leans forward to kiss him and starts to grind on him, saying with a giggle, "Hey, that only happened once when ah was 21 and drunk!"

I chuckle back and say, "Ah know, because ya bit me ya lil shit. Now shut up and ride me like a wild bronc."

Sherry grins and then sarcastically asks, "With or without the heels?"

Knowing she already knows the answer, I pull her head down and kiss her deeply as I feel her rock her hips back and forth. When she sits up, I find the stickiness of her insides a little unusual and slip a couple of fingers inside her, wiggle them around a bit before pulling them free and tasting them, saying, "Hmm, ah love how ya taste like maple syrup, ah know where to get some if and when ah should ever run out..."

She sniggers and lays her body on top of him, feeling him at the entrance to her womb, saying, "Ya better take good care of this precious commodity then, uncle." then pushes down hard and feels him pop through the opening.

As she sits up again and starts to go wild once more, I sit up and pull her left breast into my mouth and suckle on her nipple for a little while as my tip grinds against the walls of her uterus. When I pull off, I wonder aloud, saying, "Ah wonder how yer breast milk would taste if ya ever decided to bear a child..."

Sherry huffs and says, "Would ya be willing to put up with a dryad driven crazy by pregnancy hormones for two years until ah give birth? If so, we can be intimate until ah do become pregnant...though ah will ensure to put ya through the wringer for getting me pregnant in the first place."

Knowing that she is being sarcastic, I throw her for a loop, saying, "Ah'm already fathering close to a dozen children with mares ah'm not dating, ah think we should try it."

A blush crosses her cheeks as her first orgasm quickly approaches while she feels her womb lowering, but is pushed back up by his long member and moans in delight, thinking, 'UGH, I nearly forgot how he wanted kids to help him with the farm, thank god that he didn't have any with that bitch Trisha. I might have to think it over in the following months of spring...'

I then feel my own orgasm rapidly approaching when I hear my niece moan as her body shudders, feeling something warm and sticky ooze down over my shaft and balls. Her climax triggers mine as I grip her hips hard and pin her against my base, feeling each pulse being shot into her depths.

Sherry watches her abdomen as it begins to swell, smiling and saying, "Oh wow, ah wonder how big ah'm gonna get with your seed filling me..."

---

Marble wakes first to feel a shaking bed and looks around to find Roger's member disappearing into Sherry's nethers as she lays on top of him with her feet propped up on his thighs. She blinks in surprise at seeing the speed that he is driving into her, but then notices how big her abdomen is and grins when she realizes it is a cum-belly. A sweet smell catches her interest as she struggles to crawl across the bed to the source, eventually finding it coming from Roger's niece's entrance. Cocking her head, she sticks her tongue out to taste it and smiles widely at discovering it tastes a lot like maple syrup, saying, "Lime, Lime, get up and taste this!!"

Limestone groans with discomfort as she looks down at her abdomen that looks ready to explode, saying, "I can't feel or move my legs, you bring whatever you want me to taste to my lips."

She grins and nods, saying, "Alright then, one moment..." then sets to work getting as much of the nectar into her mouth when she hears a feminine guttural groan followed by a large amount of nectar oozing out around his member and sucks most of it into her mouth. Making her way over to her sister, she opens her mouth and places her lips against hers, then shares the nectar with her through a deep kiss.

Her eyes go wide at the sudden kiss, but then she tastes the sweet maple syrup and tries to devour as much of it as possible. When the flavor slowly slips away, she whines saying, "Awwee, I wish there was more..." Then asks curiously, "Where did you get that, anyway?"

Marble smirks and says, "Well, it came from Sherry after she climaxed." then looks over at her to see her abdomen even bigger than it was previously, saying, "Wow, she won't fit through a door hardly being that size." Feeling sorry for her, she then giggles and says, "Let me help you shrink down a little..." With a look at Roger, she says, "Okay, time to pull the plug and take away some of the excess."

Sherry groans, barely conscious from the multiple creampies she got from her uncle, unable to speak when she feels his member pull free, only for a pair of lips to suck her entrance into their mouth. Able to hear an audible gulping, she weakly lifts her head to see that it is the younger sister drinking the excess seed bloating her uncomfortably. When she reaches for the mare's head, she pulls her further against her entrance and groans, "Time to feed the little one, swallow fast because ah'm pushing."

Feeling a sudden torrent of cum gush into her throat and completely fill it, she plugs her nose and gulps rapidly but isn't fast enough as another rush of seed pushes against her stomach and forces it open. As she is force-fed cum, she wonders how big she will be once Sherry is comfortable.

A few minutes passes as she pushes the remaining bit out into the mare's body, letting out a relieved sigh, saying, "Thank you..." before passing out and slipping off her uncle's body.

Marble takes a quick breath and forces herself to hold the cum in her stomach while she tries to get off the bed without spewing the contents everywhere, proving to be quite a challenge as her hooves can barely reach the ground. Having to somewhat hop towards the door, she slowly makes it there when she encounters a slight problem...she is too full of cum to waddle or hop through the frame. Not letting herself be deterred, she tries wriggling her way in from side to side like a snake and slowly makes progress.

It takes her ten minutes to wriggle past the doorframe and reach the toilet, with a smile, she lifts up the seat and hangs her head over the bowl's edge and lets her hold of the seed in her stomach slip, saying, "Bwehhhh..."

Having to flush several times to avoid flooding the floor, she eventually finds relief as the only remaining seed inside her is stuck inside her womb pleasantly. Trotting back through the door, she plays with her abdomen a little before hopping back up onto the bed, rolling her sister to a spot where she can be comfortable and then lays beside her, saying in a soft whisper, "I think we will be needing to rest up for at least half the day before heading back home with the rocks."

---

Limestone sighs and corrects her, saying, "We will be taking the whole day off, once we can walk...we are going to pay a visit to our sister and share the news with her."

Marble smiles widely as she says, "Yours is gone too?! That's great to hear, everyone is going to be so happy to hear that we're going to be mothers! But wait, what about Maud?"

She hastily shushes her sister, saying, "SHH! She plans on getting a foal as well, but I will keep it a secret of what she told me... Now get some sleep, I will need your help tomorrow to go pee..."
