	Applejack looks over Sweet Apple Acres with a smile, it was time for some good ol' fashioned apple bucking.  Big Mac approached with a cart and several baskets while Applejack inhales sharply, taking in the scent of morning dew and apples.

	“I love the smell of apples in the morn', don't you big bro?” Applejack says with a smile, looking at Big Mac who just nods.

	“Eyup.” He replies.

	“Well lets get started!” Applejack said while Big Mac drags the Cart full of baskets up to the first set of trees, both him and Applejack grabbing baskets with their mouths and scattering them about the trees.  Then it was apple bucking time.  Both Applejack and Big mac buck fiercely at the apple trees, making their fruit fall from the stems and landing perfectly in each basket.

	After they finished the first section, they began to set up for the next section of trees, throwing baskets around and bucking the trees for more apples.  At one moment Big mac goes up to a tree which is larger than the rest, he didn't pay too much mind to why it was larger, until he heard it.

	Big mac nearly bucked into the large tree but then the sound filled his ears.  It was like a low thumping sound, almost like a heartbeat.  Big mac puts one of his hooves on his own chest to feel his own, but it wasn't his own heart.  He was a bit confused  now from the steady beat he heard, then he realized that the sound was coming from above as if there was something above pulsating.  He thinks to himself and finally bucks the giant tree making the large red apples fall from the branches, and that's when he saw it, the apples were throbbing, they even had a couple of veins on them.  He just stares at them, not sure what to make of this.

	“Sis!” Big Mac finally calls out with a bit of concern, Applejack quickly gallops over to him.

	“What's wrong big bro?” She asks, Big Mac answers by picking up one of the apples with his front hooves, showing it to Applejack.  Even Applejack didn't know what to make of this, a pulsating veiny apple?

	“What the hay?” She could only say as she grabs at the apple with her front hooves, sitting down and examining it.  She turns it about and pokes at it's throbbing surface.  She even puts it up to her ear and listens to it, it was definitely emitting some kind of heartbeat.  The beat was kinda soothing to her as she had listened to it for a good minute.

	“Is it rotten?” Big Mac asks while Applejack just stares at it some more.

	“I.. I don't think so” Applejack says while turning it around some more, before she hands it back to Big Mac. He just looks at it some more, feeling it pulse in his hoof.

	“Maybe I should... try it?” Big Mac asks while he eyes the pulsating fruit. Applejack shrugs a bit and also eyes the apple, still not sure what to make of it.

	“Well it's just throbbing... I mean... throbbing doesn't change the taste of a good apple I think.” Applejack says while musing about it.  Big Mac stares at the apple as he brings it up slowly to his mouth, he slowly  sinks his teeth into it's throbbing surface, getting a nice chunk of it.  He realizes that the veins on the apple are actually pumping apple juice through the apple as some of it squirts from one that got bitten off.  Big Mac chews and swallows that piece of apple.  He looks down to the half eaten apple with a smile after wards.

	“Hey, this is pretty good.” Big Mac says as he takes another bite from it, Applejack watching and grinning.

	“Well it looks like even the throbbin' apples are even good here in Sweet Apple Acres!” She says with a chuckle.  Big mac quickly finishing up the apple.

	“Eeeyu...” Before Big Mac could finish he could feel something odd in his stomach, an odd throbbing sensation  over his gut.  He could feel it distend a little and he blinks while looking down at himself with wide eyes.

	“Bro? Are you alright?” Applejack says with a bit of worry.  Big Mac just rubs one of his front hooves on his belly, it definitely felt bigger.  But what he felt next made his pupil shrink to dots.  It was a pulse, in his growing belly.  He pants a little as the feeling of it getting bigger is quite intense for him, he had to lay up against a tree  just to see what was happening with his belly.

	“I-I think it might be gas.” He says while watching his belly distend more and more with every pulse it makes. Applejack just looks on in horror as it just keeps getting bigger.

	“B-bro! Yer inflating like a balloon!” Applejack says while watching her brother's belly grow, seeing his navel quite visible now, but what really shocked her was the way it started to throb.  They could both hear an audible heartbeat from it as it bounces a bit from each beat. It seemed to have stopped growing, but it was growing and shrinking with each heart beat.  He put a hoof onto his own belly as it beat like a heart, feeling a pulse from it.  Big Mac found that his gut was beating to a rhythm that was alien to his own body, he discovers this as his own heart rate is sky rocketing from all these weird sensations.

	He blushes as his hoof presses into the throbbing gut, his newly grown belly ultra sensitive to the touch, which would send shivers to the stallion's body.  Applejack just watches as her own brother moans softly as he begins to rub over his pumping gut with both of his hooves now, she rubs the back of her own head at this, wondering if she should really be watching this.

	“Uh.. you sure are enjoying rubbin' yerself there bro, despite what just happened.” Applejack says while trying to look away but his throbbing gut was too mesmerizing to look away from.  He just rubs over the tight throbbing surface of his red belly, each rub sending more shivers through his body, but when he finally reaches a hoof down to his navel, he shudders violently at how it was the most sensitive part on his body now.  He begins to rub desperately at his navel trying to get it to throb harder or faster, but it just kept at it's steady beat.  He writhes about at how good each throb of his belly felt, he wanted to feel more of this immense pleasure.

	“WHOA NELLY!” Applejack suddenly shouts out, getting Big Mac to suddenly snap back from his pleasured trance to see his stallion cock fully hard and his sister just staring at it a bit.  Both of them blushing a hot red while Big Mac's cock just bounces rapidly to his speeding heart.  Then Applejack slowly turns away.

	“Uhh... I’m gonna... leave you to this... until yer done... and stuff...” Applejack says sheepishly, then makes a run for the farm house.  Big Mac just blinks but then goes back to kneading his enlarged belly with his hooves.  No matter how much he rubbed it, he wanted more of this, he wanted the belly to beat faster.  He turns to the bucket full of throbbing apples and grins.

	Big Mac quickly grabs an apple and scarfs it down.  He then smiles a bit as he looks to his belly, waiting impatiently for any change to happen.  Then he feels what could only be described as an electric shock to his entire body, he pants and moans softly as he gets the results he wanted, his belly started growing more.  He  could feel it expand from all directions now, but it manages to stay well rounded with each throb it makes, soon veins became visible all along the sides of the belly which throb quickly with his racing heart, but the entire belly itself just keeps at the steady rhythm.

	Soon his navel pops out, becoming a large throbbing knob in the middle of that giant belly.  The belly was as big as the stallion now, his rear and front hooves rub all over the sides of it, the feelings were so intense that just the simple rubbings was making his cock drool precum.  He reaches up the the giant mountain which was his gut to rub at that pumping navel that seems to be throbbing harder than the entire belly itself, he wanted to know how it would feel to him.

	After many attempts to reach at it, he pushes the throbbing gut forward with his rear legs which lowers it enough so he could finally reach it, and when he did...

	BATHUMP BATHUMP BATHUMP

	He moans in pure ecstasy as just touching the navel sent bolts of pleasure to his entire body, especially to his heart which was now beating frantically.  At this point he tries desperately to get a better reach of it but couldn't so he just settles for lightly rubbing against it's steadily throbbing surface, he closes his eyes and moans out constantly as his light rubbing continues to send pleasurable shocks to his body, his cock was throbbing so hard that it was slapping hard against the underside of his inflated throbbing gut, the tip drooling precum now. He closes his eyes and takes in all the feelings.

	You need a hoof with that bro?

	Big Mac suddenly opens his eyes again to see Applejack's face upside down to him.  He blushes fiercely as his sister seems to be giving him a suggestive smile at her offer.

	“S-sis? What are you...” Before he could finish, Applejack puts a hoof over his mouth and shushes him, then she lifts her hoof and gives him a grin.

	“Well I couldn't leave ya all pent up like this now can I? Wouldn't be sisterly of me!” She says with a grin.

	“I.. Suppose...” Big Mac manages to say. Not sure what else to say.

	“So you want mah help?” She asks again, he looks down at this pounding round navel that is now pulsating harder with need, he just quickly looks up and gives a worried grin.

	“Y-YUP!” He shouts as his need seems to be over powering his sense of taboo right now.  He thinks about how good it felt with his own hoof, now thinking how good a rub from some pony else would feel.  He lays out as he braces himself as Applejack slowly trots to his side.  He breathes deeply with his heart pounding heavily in his chest.  Then she lifts a hoof and rubs at the side a little, making a soft moan escape from Big Mac's muzzle which make Applejack chuckle a little.

	Soon Applejack hops onto Big Mac's belly, standing right on the center of it, some how managing to keep her balance on it as it heavily throbs under her hooves.  The giant belly was tight and firm under Applejack's hooves, Big Mac panting harder as the feeling of four hooves pressing down over his belly.  Applejack looks down to the center of the belly to see that large pulsating navel in the middle.  She  then teases it lightly  with one of her hooves.  Big Mac grunts and moans as the feeling of another hoof really did feel twice as better if not more than his own.

	Big Mac writhes a bit in pleasure as Applejack starts to kneed over his inflated throbbing navel.  He couldn't believe how good it felt, only a little disappointed that his throbbing belly only kept at a certain rate.  But he couldn't argue with the immense pleasure he was feeling right now.  Applejack watches as her big brother constantly moans and pants, she even looks back to that throbbing erection of his as well, seeing how it could go off at any second if she kept this up.  So she continues.

	Big Mac's eyes suddenly go wide, he could see that his sister is now squeezing the giant throbbing knob on his belly with both of her hooves, it was that point where he lost it.  Big Mac hollers out which sounds like a loud moan and a whinny at the same time.  His huge cock bounces heavily now as it gushes forward thick ropes of his seed which fires forward, getting the earth in front of where he was laying covered in the thick spunk.  Applejack still rubbed up and down his navel with both of her hooves, despite the fact Big Mac was already going off like a fire hose.

	When Big Mac's orgasm ended, he was still hard, still feeling all that pleasure from Applejack rubbing his throbbing gut and  navel.  It still throbbed steadily and heavily against His sister's hooves.  He couldn't believe that he was already feeling close again, just moments after showering the ground in front of him with his seed.  Then Applejack puts her maw over the throbbing navel, sucking on the round throbbing flesh.  The sensations make Big Mac abruptly cum again, making him moan out and spray more of his seed in front of him.  It wasn't as large as his first load but still just as satisfying.

	Big Mac started to feel a little dizzy from the sudden two orgasms, but was in amazement as he was STILL hard.  But that's not all, all the attentions given to his gut finally increases the speed of it's throbs, if not only a little as Applejack rubs all over that navel, sucking and licking all over it as well, giving it all the attention which Big Mac wanted so badly.  He can feel his heart pounding more madly than before, he holds his hooves over his chest, feeling how hard it's working right now as his sister continues to work over that knob as if she was worshiping it.

	Then it finally happened, Big Mac's belly suddenly starts throbbing faster and harder, he groans out as he achieves his third orgasm, but this one was far more intense as his belly goes into a throbbing frenzy as if it just had an orgasm as well, each increased beat sending huge waves of lust through his body with each beat, while Applejack hangs on for dear life.

	“YEE HAAW!” Applejack shouts as she rides the gasming belly like it was some kind of bucking bronco.  Big Mac coats the ground in front of him with even more of his seed.  Soon The orgasms pass and Big Mac just lays still, panting heavily moments before his eyes roll into the back of his head, slowly passing out from all those intense orgasms.  He could feel his belly calm and pound at it's normal rate again.  But before he completely passes out, he could hear two different voices...

	Oh my... he's quite a big stallion...

	Yesss... She'll have so much fun with him.

	I'm sure she already felt it with that last orgasm.

	Well lets get him back, we need to get the others as well for our plans!

	Yes! The plan... er what was the plan aga.....

	Soon Consciousness left the tired stallion's body.  Although with a bit of concern with what he just heard, he could only feel his belly throbbing and it felt so nice.  But soon his dreams are haunted by what he just let his very own sister did to him... Or did she really do it?
