A Seed of Temptation

“Hey, Big Mac!”

AppleJack called down the hall, her southern drawl nothing more than the sound of home.
The stallion in question brought a hoof to his face, rubbing the sleep from his eyes.

“C’mon, big brother! Wake up!”

Applebloom trotted down the hall, a skip to her step.
He sighed. Lately, there had been times when Applebloom’s voice had startled him out of sleep. As the filly had grown into a mare she had begun to sound more and more like the faded memories of mother he kept stored away. Today, however, was not one of those days. The impatience in her tone and higher pitched squeals he could hear coming from the kitchen still reflected her recent transition to marehood.

Big Mac stretched out each leg before rolling onto his belly, a rear hoof in the air off the edge of the bed. His weight shifted, he could now feel the seething pressure balled up between his legs, a thick cable pressing against his grumbling stomach. The covers lay on the floor where he must have tossed them in his sleep. Once more he sighed, glad that his sister had learned no to barge into his room. A brief shudder traveled across his skin, as the memory surfaced of a much younger Applejack trotting in unannounced to be covered in a wave of white.

He shook his thoughts free and began to step off the bed. He could feel an uncomfortable pressure as the edge of the sheet, loosened by his rough slumber, caught the swollen tip, hooking around it and pulling it down. He pressed forward, dragging his last hoof off the bed, enjoying the stretching of his muscles. The sheet continued to pull backwards on his taut member, the stretching sensation relieving some of the built up tension. He winced as it popped shortly before the sheet released it.

He shook himself, dislodging his mane from the messy mat it had solidified into during his sleep. Hooves clattered down the hallway, once more accompanied by the chatter of his youngest sister.

“Bic Mac, you big oaf, you awake, yet?” She tap-danced on the other side of the door.

“Eeyup.” He picked his blanket up and tossed it in a pile on his bed.

“Well, hurry up and get ready, we gotta go. Babs is gonna get here soon.”

He flicked his ear in an unseen response. Today was the day their Manehatten cousin would be coming to visit. He opened the door, his sister already trotting back down the hallway, her bow bouncing with her trot. He turned towards the bathroom, his large form hiding the shrinking mass hanging beneath him. Splashing water on his face, in lieu of a shower, he thought about his cousin. In his memory, it was Applebloom who last traveled to Manehatten to see their cousin. The last he saw the city mare was the funeral, or at least he thought she was there. He didn’t pay too much attention at the time, his sisters were more important. He shrugged as he rubbed against the towel hanging on the wall. She’d be a full-grown mare now as well, he figured, but that really didn’t mean anything other than she’d be less likely to get in trouble now.

--

Ponies strolled idly by the station. His sisters gossiped ahead their farm-weathered forms highlighting their sisterly bond. The platform itself was swarmed with ponies of every color with even a few other species milling about. His sisters were soon lost in the throng, even Aj’s signature hat was indiscernible among the crowd.

His immense size made it easy for him to peer over the ears of his fellow ponies, but he wasn’t quite sure who he was looking for. His memory was a tad fuzzy as to what color his cousin's mane or even coat was. After all, every reunion brought more and more cousins each year, making it hard to keep up with what any of them looked like.

“Ahem…” The vague clearing of a throat slid past Big Mac’s ear in his silent concentration. “

“I said, ahem!” This time Big Mac’s ear swiveled towards the sound. At his flank was a beautiful young mare with a chestnut coat and grass-green eyes. He fidgeted a moment looking down at his feet thinking he was blocking this mare’s luggage.

“Ay! Whaddya doing? A dance or somethin’?” Her lilted voice made him look back up again. She had stepped closer and he could see that the flaming pink hair was natural, her ears laden with a couple of metallic pieces adoring her flicking ear tips. Her beauty was distracting, graceful curves traced from her withers to her flanks. A tap of a hoof on his shoulder and the sharp smell of metal and brick accompanying it brought him back to his senses. He realized the mare seemed irritated with him, words rapidly flowing from her mouth accent slurring them together.
At this point, he could hardly understand what she was saying. The mare seemed familiar, but he couldn’t place why.

Big Mac was relieved when he heard his sisters calling to him from the crowd. Relief blossomed for a moment as he turned towards them. They must've found their cousin and could take him away from this beautiful, but confusing mare.

“Hey Big Mac, you found her!” Applebloom set her sights behind him. “I can’t believe how many ponies there are here today, you’d think Princess Celestia, herself, was on this train.” Applejack was also looking behind him. Confused, Big Mac turned back around to see the mare behind him focused on his sisters, a grin on her face.

“I’m used to these sorts of crowds, but I’m glad Big Mac is so, well, big. Has he hit his head or somethin’? This big yutz was acting like he’d never seen me before.”

The mare walked around him and greeted both of the Apple sisters with a hug, as the puzzle pieces began to fit in his head.


“Babs?”

His cousin gave him a bemused grin.

“Yeah? That’s my name. Don’t wear it out now.”

His gaze flitted back and forth between his Applebloom and Babs. He barely noticed the weight being placed on his back by Applejack. He knew the two mares were close in age, and his sister could definitely be described as good-looking. He guessed years of farmwork adding muscles to her figure and the fact he was there when she was foaled, must have lowered his inclination to find her attractive. Not that he wanted to find his baby sister attractive in any way. He shook his head briefly before continuing his observation. Babs on the other hand was still in decent shape but lacked that roughness that years of bucking apples can add to a pony. Her style also added a layer of mystique to her. She had her mane and tail cropped short and earrings studding her ears. Her hooves seemed to carry a trace of color beneath the Apple family fetlocks. Even those were styled into jagged teeth with a purple shade beneath showing through. Mentally a voice threw up a wall in his thoughts, plastered over with the various phrasings of ‘she is your cousin!’.

Aj popped up in his vision, looking concerned.

“Hey, you okay? You're looking a little lost there.”

The two mares were already walking off, heads tossed back in laughter. His eyes darted side to side as he gained his bearings.


“Uh.. eeyup..” Weighted down with bags he slowly followed them back home.


---
The sun had now strayed farther into the sky, as he silently plodded his way back to Sweet Apple Acres. His belly rumbled lightly causing him to regret not grabbing a snack on the way to the station. During his slow parade home his mind had pushed his ruminations aside instead focusing on his other tasks for the day. His hooves plodded along following a years-worn path through the gate, as he nearly put himself back to sleep counting how many barrels he would need to put in each wagon for maximum efficiency. He was simply standing in front of the house lost in a trance, calculating the average size of an apple compared to zap-apples, when Applebloom ran out past him followed shortly by Applejack. She stopped in front of her brother with a concerned look on her face.

“Oh, there ya are, Big Mac. We’d thought you’d gotten lost.” She glanced over at Applbloom who was at the edge of the yard dancing on her hooves. “Anyhow, Babs is upstairs gettin’ settled in. On our way back we had the third sign. There were crows everywhere. Me and Applebloom are gonna go check the trees to get an idea of the harvest.”

Meanwhile, Applebloom had run back over, impatience quivering in her bow.

“And if we hurry we can get done before sundown!”

“I hear ya. Better take Babs her stuff.... and maybe you should get some rest we hope to fill the barn with jam this year... See you later.”

He watched both of his sisters gallop off to the orchard where the usually bare zap-apple trees stood.

“Those two always had too much energy.”

Big Mac’s fur trailed along his skin as he jumped at the new voice. Bab’s stood at the doorway, her vibrant green eyes watching him with a sly smirk on her face.

“Man, cousin, you sure are jumpy today.” She glanced at the fading dust trails and then the sun’s climb in the sky. “Well, Ya gonna stand there all day?” She walked over and took one of the small bags from his back and with a flick of her head motioned for him to follow.

The creaks of the old stairs filled his ears as he followed the supple flanks of the mare to the second story. Despite the familiar feel of the bowed wood beneath his hooves and the walls he tripped on the crooked second last step due to his intense blushed focus on the ceiling rather than the mare before him. The bag on his back went flying and hit the wall shortly before his head.

Wooziness made everything blur as he sat up, a hoof to the new swelling on his head. As he set the hoof back down he felt a soft material beneath it. He squinted beneath him where Babs lay caught beneath him. Awareness came to him of her rear firm against him just above his groin. He backpedaled rapidly, barely correcting his trajectory to the wall behind him. The impact knocked a gilded frame of granny on his head, further agitating the sore now forming beneath his locks and distracting from the swelling between his legs.

“Ey, ya big lug! Watch where ya goin’ “

Babs pushed herself up with her forehooves, an emerald anger in her eyes. She shook herself off and picked the bag she was carrying off the floor.

“Jeez, you’re heavy” She mumbled around the handle before slowly walking into the room, his old one they now used for guests.
He took advantage of the silence, giving himself time to stop the world from spinning and his mind from wandering.

“Hey, didn’t we tear this quilt one year?”
“Ack, all this dust. I think this was here before, too”
“Where’s my other bag?”

He could hear her mumbles from the open door. He got back to his feet, inhaling deeply. The large bag was still set against the wall. He picked it up, letting it hang in front of him rather than toss it on his back for such a short trip. He took another deep breath before entering the room. The wooden handle on the bag was convenient given the grip his teeth now had on it. Upon stepping over the threshold he saw the mare bent over shuffling around in a lower drawer. From his vantage point her short tail scarcely covered the soft skin of her teats, teasing the view of her pink lips.

He could feel his sheath begin to stretch as his bulge grew, air nibbling at the exposing tip. Heat flushed his body with both desire and shame. At this point, he knew he was staring but sense, it seemed, had abandoned him. Luckily the bag in his grasp concealed his form. Though drool began to form at the corners of his mouth and the handle started to slip. Her tail swished as she bent further into the drawer widening her stance to do so. This gesture gave a full glimpse of her now parted lips and the redder flesh within.

SLAM!

The bag fell to the floor making both ponies jump. In an attempt to hide himself, Big Mac drew his legs together the best he could, squeezing the expanded orbs between them. This caused more pressure to build up at his base and for the whole of the shaft to twitch, the motion grazing his paler belly fur.

Babs jerked up, conveniently with enough sense to move outward and back rather than up into the ceiling of the drawer.

“Buy Some Apples!”

The instinctive curse fell from her lips at the start. She swung her head around the verdant fire lit.

“What is wrong with you!?”

She stomped over to the red stallion, who was quite thankful he couldn’t get redder. Her hot breath was cooler than the heat currently radiating through his face.

“I don’t understand what has gotten into you.”

She pressed forward her muzzle a hair-breadth away from his own. Experience concerning confrontations with angry mares convinced him that retreat was his best option. With heavy hooves, he slowly stepped backward and once more his body betrayed him as his hoof caught on the transition strip of the door. He fell backward on his flanks, his cable-like member now slamming into his stomach. Pressure increased on the pliable spheres at his groin.

“Ever since I got here you’ve been actin’ funny. And don’ think I didn’t see you staring at me all day.”

Sweat formed on the stallion’s brow and the stress built up in his entire body. Her eyes pierced him through, raking down his body. In the reclined position the paler, darker, leaning towards a shade of brown flesh was visible framed by the bright red fur of his muscular haunches. Looser flesh pooled around two ovular shapes while a more taut veined length of muscle held itself aloft at the length of his foreleg. Her eyes landed on the twitching tip for a moment before glaring back at Big Mac’s frightened pupils.

“So that’s how it is.”

She looked away for a moment, stomping a hoof.

“I thought you were my cousin. You were like a big brother to me… but now. “

Hair fell lightly down over her eyes and a quiver appeared in her voice. Big Mac felt the shame build up within him again threatening to swamp the desire.

“I see it. You’re just like any other stallion.”

A growl replaced the quiver and when she met his eyes once more a dark light within. Fear sparked next to the shame booming around like lightning within.


“You want this eh?”

She pounded a hoof against her chest, anger building. He flinched at the sudden movement, his emotions in turmoil. Sweat now trailed down his face, leaving dark red trails in their wake.

“Well. ya better be careful what you wish for.”

Suddenly the scenery changed and the hard floor became much softer. Babs was above him now pressing her hooves onto his chest. His mind was whirling in the seconds it took for him to process Babs throwing him onto the bed. There was a pain in his thighs as her hooves pressed them apart. His heart raced.

“What’s this? You can’t be scared now, this is what you want, eh?”

At the moment Big Mac wasn’t sure what he wanted. There were several warring thoughts in his head. First was the confusion as to what in the world just happened. Second was the fact that a mare now hovered above straddling him. Third was a contemplation of whether or not he should shift himself and let her slide onto him. The fourth, this one sounded like an air horn, was a mere exclamation of “SHE IS YOUR COUSIN!”

She lifted up her hooves and pushed him back down further into the downy bedding. While his mind was occupied his body reacted to the warmth hovering above it and throbbed with anticipation. She shifted her weight moving her hooves onto the blankets. As she shifted forward, he could feel a dampness brush his sensitive skin. The weight pressed harder on his chest and squeezed the air from his lungs. The mare let her weight fall to her knees as she positioned herself just at the top of his large column. Done moving she lifted her front and let gravity slide her downward.

At this point, Big Mac had found it hard to breathe and the return of precious oxygen had distracted him slightly from her warm and wet embrace. Babs grunted as he filled her up with his tip grazing her insides.

Big Mac is definitely a fitting name for you, cuz.”

Determination filled her eyes and she started to rock back and forth slowly. By now the speed of recent events had left him stunned, yet her slow and steady sway atop him paved the way for desire to take hold. His hooves lifted off the bedspread and cradled her flanks. At first he let them glide with her before holding tighter and encouraging her thrusts to move faster. The pressure commenced building up again and the rest of his thoughts were allowed to settle beneath the waves of pleasure building up.

“Mmmph…” The sensual moan was the first real sound the silent stallion had made beyond the prior thuds of impact.

“Yeah, that’s it. Go ahead and let it all out.” The chestnut mare let her hips follow the stallion’s hooves, slowly pushing faster.

Out in the yard, a pale yellow mare galloped in from the fields, her bow bouncing atop her strawberry-colored mane. Inside the ponies were unaware of the other mare’s approach as she dashed inside the house. Big Mac’s ears flicked for a moment thinking he had heard, and he had, hoofsteps downstairs. This he dismissed after a moment as he felt the surge build up within him. The mare stayed in the kitchen long enough to get a drink of water before walking to the stairs.

“Hey Babs, are you done yet? You should come to see the Zap-apple trees.”

His eyes flew open and another unbidden moan slipped past his lips. “A-aaappleblooom?!”

He tried to move, sit up, or dislodge Babs from her position atop him, but his efforts were met with sturdy hooves forcing him back against the covers. A smirk road on the mare’s face.

“Hey now, we ain’t done yet. I’m not stoppin’ til you give it to me”

She forced his hooves down, leaning forward and giving more power to her thrusts. He began to squirm, part under the pressure rapidly building up in him and part due to the hoofsteps he now heard coming up the stairs. He shook his head and desperately tried to remove himself from the situation but Babs held firm. In fact, she simply rocked her hips faster each cycle, her walls heating up and growing more slick. With the acceleration, his willpower decreased, and his struggles subsided to simply keeping his mouth shut.

The hoofsteps grew closer just a few taps from the top step. He squinted his eyes, jaw clenching.

tap, tap, tap


With a grunt he couldn’t hold out anymore and release poured out into the mare, some leaking out onto him. Like his transition onto the bed, he was on the floor beside the wall before he knew what was happening. There was a rustling of covers above him shortly followed by the sound of his sister calling through the doorway.

“Babs?”

The bed creaked lightly as his cousin shifted.

“Enhh...yeah?” He was surprised at how groggy the mare was able to sound. Keeping his own breath under control was hard at the moment.

“Oh, did I wake you?”

As the two mares conversed he looked down at himself. White semen was still dripping down his length and the glans swollen. Horror at what just happened caught in his throat. He just came in his cousin. His cousin for Celestia’s sake. The cousin who is the same age as his youngest sister. The only pressure left in him now was shame, burning its way through his insides.

“ yeh, I was tired... from the train ride and all. Thought I could catch some z’s.”

“Oh, okay. I can show you later. Hope you can get some rest.”

Applebloom left the room leaving the two ponies alone once more. Babs leaned down her breath wet on his ear.

“I hope you learned your lesson.”

Whether or not Applebloom decided to come up the stairs it didn’t matter. He was too close. There was a mare, a real mare, here. Every thrust let him feel her hot slick insides. This was much better than his hoof. Desire raged within him and he gave in. He no longer tried to squirm away instead he thrust against her, trying to stay within that feverish cocoon. He could feel it like a white light drawing near.

Another few moments and… nothing. Cold struck his now bare cock, his muscles clenching at the sudden change. Babs now stood beside the bed with a sly grin on her face. She nudged his shaft with a hoof, inciting a whimper from him. Her smirk grew wider before she turned and called out.

“Yeah, come up here I’ll be just a second.”

His hoof had already begun to wrap itself around his member when she called out. He knew he should stop and figure out how to calm down, but he was so close. In a moment of panic he rolled off the bed landing next to the wall just before Applebloom stepped in the room. The mares talked for a bit before they turned to leave the room.

“Hold on a sec, I just gotta grab something.”

Babs appeared over the threshold gazing with satisfaction at Big Mac who lay there sheepishly, his belly and parts of his face smeared in white.

“I hope you learned your lesson.”
