“Have a good night, Dad!” Shining waved, closing the door behind his father. He had the entire evening to himself, free from his parents and little sister, and he knew exactly how he was going to spend his time.
Velvet and Twilight were both gone for the weekend on a school field trip to Manehattan. His mother had volunteered to assist chaperoning the class, meaning she and Shining’s sibling would be absent for the better part of three days. Night Light, much like his name suggests, worked third shift, which meant the young stallion had the house to himself until sunup.
Peeking through the blinds of the front window, watching the azure stallion depart for work, Shining grinned to himself. Double-checking the locks on the front door, he scampered upstairs. There were very, very few times he could do as he pleased in the house, considering someone else was almost always home, but this weekend was the exception. Strolling down the hallway, he made a beeline towards his parent’s room.
Over the past few months, he’d developed a rather unique hobby. It had all started when Cadance, his girlfriend, had goaded him into trying on some of her clothes. At the time, she’d joked about how feminine he looked, although the experience sparked an interest within him. He didn’t consider himself gay or anything, but wearing frilly, alluring garments just sort of turned him on.
All throughout school, he’d always been on the slender side. Where other stallions had filled out with broad shoulders and toned physiques, Shining’s body had never really blossomed. A full waist, plump tush, and lithe figure were all he’d ever known. Cadance didn’t seem to care, although a few of his fellow seniors would, at times, pick on him about his build. Still, after seeing himself in the cerise alicorn’s negligee, he had to admit, he could easily pass for a mare.
Even his stallionhood wasn’t all that impressive - at least, compared to his classmates. Growing up, he’d always assumed he was adequately hung, although his first trip to the locker room had changed that. Even flaccid, a great many of his fellow ponies sported equipment larger than his fully erect member. Not that it particularly mattered, since his girlfriend was satisfied with him, yet it was still a bit embarrassing.
Still, given his growing interest in the matter, Shining had noticed something; his mother appeared to have almost the same build as him. He was just a hair taller than she was, but their muscle tone was remarkably similar. With that in mind, there was something he’d been wanting to try for quite some time.
Cracking the door to his parent’s room, he peeped within. Logically, there was no reason for him to be so cautious, since he was home alone, yet he was still anxious about the endeavor. Slipping inside, he crept to Velvet’s dresser. A number of perfumes and makeup items sat on its surface, below a large mirror, but that wasn’t what he was after - no, he was far more interested in what lie within the piece of furniture.
Sliding the top drawer open, Shining paused and gazed at the contents. There, neatly folded and arranged, were his mother’s panties and bras. Peering over them, browsing the various patterns and fabrics, his eyes ultimately settled upon a pair of lacey violet boy shorts. Noting exactly how they were arranged, so he could return them without being noticed, he snatched them up.
Selecting a similarly patterned bra, he stepped away and placed the undergarments on the bed. Pulling his t-shirt over his head and tossing it to the floor, Shining began fiddling with his belt. He could feel his pulse quicken, as he let his shorts slip down his legs. Hitching his thumbs over his briefs, he hauled them over his rump and down his thighs.
Being prompted to wear his girlfriend’s clothes was one thing, but sneaking into his parents room to try on his mom’s lingerie was so much more scandalous. Now nude, he picked up Velvet’s boyshorts. Bending over, stepping one foot into the delicate bit of fabric, he swallowed hard and started dragging them upward.
The sensation of his stallionhood trapped within the lace was painfully arousing - so much so that he started to feel himself getting hard. Still, he couldn’t bring himself to look himself over; not until he’d finished the job. Grabbing the bra, he slipped his arms into it, reached back, and secured the clasp around his back.
Brushing his shoulder-length mane from under the straps, Shining closed his eyes and took a deep breath. Turning towards the mirror, he steeled his resolve. A part of him realized the entire affair was foolish, yet he was compelled. Peeking out, he caught sight of his reflect and froze.
Standing before him was the most gorgeous stallion he’d ever seen. The rich purple of the negligee flawlessly complimented his alabaster coat and sapphire mane. Sure, the bra didn’t suit him especially well, since his chest was relatively flat, but the boyshorts fit him like a glove. A slightly tented bulge sitting at his groin, beneath the net-like material, was the only true sign that he was a stallion at all.
The excitement of such a taboo act was amplified exponentially by the fact that he’d snuck into his parents room to do something so outrageous. It was bad enough that he’d dressed himself like a mare, but he’d done so with his own mom’s clothes. Anxious, fearful, and a little horny, he looked himself over. Stars above, if he got caught, he’d simply die of embarrassment, although that was part of the thrill.
Turning, Shining examined his backside. His bottom looked even more prominent than ever, stuffed into the contrasting fabric. Swinging his tail to the side, he reached back and grasped his cheeks. Again, he felt his length stiffen, as he brazenly appreciated the view. He’d had no idea he’d look that good in Velvet’s intimates, although the sight gave him an idea. His gaze wandered back to the dresser, wondering what other treasures it held.
Sauntering over, he opened another drawer and found a number of socks and leggings stashed within. Emboldened with how captivating he was, he figured that going the extra mile couldn’t hurt. Fetching a pair of black stockings, he hurriedly donned them and looked up. Now face to face with his reflection, a curious notion seized him. If garments alone elevated his feminine appeal so thoroughly, maybe a little makeup couldn’t hurt.
Glancing down at the array of cosmetics, he retrieved a tube of cherry red lipstick. Now, Shining had never tried something so audacious, but he figured it was worth a try. He’d already crossed several lines, so going just a little further surely wouldn’t make the situation any worse - besides, he had the house to himself for the next eight hours; if it didn’t look good, he could always wash it off.
Making a kissy face, he slowly applied the lipstick to himself. He’d seen Cadance and Velvet enact the procedure several times before, so it couldn’t be that difficult. Finishing up, he carefully pressed his lips together, to ensure an even coating of the glossy substance. Checking his work, pleased with his efforts, he stepped away.
A cheerful grin crept across Shining’s face, as he drank in his reflection. It was almost like looking at another person. Gone was the soft spoken stallion he’d known, replaced by a svelte, delicate mare. Giving himself his best come hither eyes, he pursed his lips. He was so turned on that he didn’t notice the tip of his member peeking above his boyshorts, nor the silhouette standing in the doorway behind him.
“Hey there, Sexy,” Shining cooed, gazing longingly at himself. Leaning over, he ran his fingers up his thighs, before resting his hands on his hips. “My, it looks like someone is worked up,” he giggled, spying his diminutive boner.
Shining’s ears automatically swiveled towards the source of the noise. Whirling around, his pupils shrunk to pinpricks, when he realized that he was being watched. Instinctively covering his groin, the stallion went rigid. There, backlit by the hallway light, was none other than Night Light.
His jaw worked silently, desperately struggling to form some sort of explanation, yet his mouth felt as though it was full of sand. His father should have been gone for the night, yet something had clearly gone awry. Be damned if he could explain why he hadn’t heard anything, but it hardly mattered. He’d been caught wearing his own mother’s unmentionables.
“Looking good as ever, Honey,” Night Light murmured, stepping into the room.
As if Shining hadn’t been confused enough, his dad’s statement caught him woefully off guard. Paralyzed, while the large unicorn drew nearer, he weighed his options. Even if he could make it out of the house, he’d have to return eventually. Graduation was only a few weeks away, he didn’t have anyone else to stay with, and it wasn’t like he had a job or anything.
Keeping his eyes on the floor, as Night slowly circled him, he tried to think of something, anything to say. Just as Shining was about to utter some hair-brained explanation about mares’ clothing and shopping for Cadance, he yelped in surprise, as something firmly smacked and groped his bottom.
“What’s the matter, Dear, not happy to see your husband?” Night asked, kneading the slender unicorn’s rear.
Shining’s mind raced wildly. There was no way that his father didn’t recognize him, so it couldn’t be a case of mistaken identity. He didn’t smell alcohol, which ruled out any chances of inebriation. With those two explanations nixed, there was only one possible option. Steadying himself and taking a deep breath, he opened his mouth.
“Welcome h...home, Honey. I just wanted to try on s...something sexy for you,” Shining stammered, forcing himself to face at his father.
“Mmmmm,” Night hummed, his eyes dancing over the sleek unicorn before him. “What can I say; with a mare like you waiting at home for me, I decided to call out for the night,” he chuckled. Stepping forward, pressing his chest to his son, he ran his fingers through Shining’s mane.
Peering up at the stallion, Shining found himself pulled into a deep kiss. His knees felt weak, as Night’s tongue wormed into his mouth. His dad had always been significantly larger than him, standing nearly a head taller, though that wasn’t the worst part. Pressed against one another, he could detect something hot and girthy on his abdomen.
Pulling away, licking his lips, Night gazed down at the effeminate unicorn. “Well, since I’m off tonight, how about you…” he trailed off, glancing towards his crotch.
If Shining had thought it was all some strange prank, the notion immediately died. Spying the substantial bulge in his dad’s pants, coupled with the lingering request, he knew what was expected of him. Shuffling back a half step, he squatted down to his haunches, bringing himself eye level with Night’s groin.
With trembling hands, he reached out and started fiddling with his dad’s zipper. Thankfully, he was given a bit of assistance, as Night unbuckled his belt and unbuttoned his pants. As the garment slid down, dropping to the floor, Shining gasped. He’d known his father was hung, although he’d never really gotten a close look at it.
Night Light’s tool was nearly as thick as Shining’s wrist. Long, vascular, and covered in velvety, midnight blue flesh. He watched, as it throbbed in tune with his heartbeat, growing larger with every passing second. As impressive as the sight was, the aroma was even more bewitching; the strong, masculine scent of stallion filled his nostrils, only adding to his excitement.
“Well…” Night whispered expectantly.
Transfixed by the growing member flopped in front of him, Shining gingerly grasped its base. Angling the length of flesh towards himself, he opened his maw. He’d never sucked a dick before, or even thought about it; but faced with such a glorious appendage, he was spurred to act. Running his tongue around its bloated head, he wrapped his lips around his father’s cock.
Thoughts raced through his mind, as he steadily bobbed his head back and forth. Until a few moments ago, he’d been sure of his heterosexuality; that being said, he had just started voluntarily fellating his dad, thoughtlessly slipping Night’s stallionhood into his maw. It was like his body was acting on instinct, filling a role it didn’t know it had.
Internal conflicts aside, there was no denying the fact that he was painfully aroused. His own tool, trapped beneath Velvet’s lingerie, smeared pre-cum over his belly. Stroking the lower portion of Night’s length in his hand, he did his best to please his unexpected partner. Taking breaths when he could, he lewdly hummed around the log of flesh.
The savory, salty flavor of his father’s package was accentuated by the virile stallion’s scent. His tongue played over the silken exterior, noting every vein and ridge along its thick length. As much as he hated to admit it, he found himself more than a little worked up by the sensation. Cracking his eyes open, his vision was filled with Night’s abdomen, as well as the shaft pistoning into his muzzle.
“Sweet Celestia, someone’s eager,” Night chuckled. Gently grasping his son’s head, taking care not to be too rough, he pushed himself deeper.
A stifled gag escaped Shining, when the tip of Night’s prick bumped against the back of his throat. Though it was a bit uncomfortable, for whatever reason, it only turned him on more. With renewed vigor, he slurped upon the stallion’s meaty cock. He was so preoccupied, that he didn’t notice his father begin to lean over him.
Deftly reaching behind the smaller unicorn, Night unfastened the bra around Shining’s chest, allowing the article to hang off his arms. As he stood back up, his eyes met his son’s, causing him to grin. “If I’d known you were this thirsty, I’d stay home with you more often,” he affectionately noted, caressing the lad’s face.
Splaying his legs, Shining closed his eyes and concentrated. There was something so wrong about servicing the very stallionhood which had helped make him, yet some part of him, buried deep within himself, urged him to continue. As his free hand drifted to his nethers, something grabbed his arm. Peering up, past the fat prick in his muzzle, he noticed a warm smile on the stallion’s face.
“Alright, that’s enough,” Night muttered, stepping away and retracting himself from his son’s pouting lips. Lipstick was streaked along his shaft, stopping just before his medial ring, although that wasn’t what had his attention - no, that honor was taken by the pleading look on the feminine unicorn’s face. “How about you get on the bed…”
Giving a small nod, Shining numbly did as he was asked. A part of him screamed at him to flee, somehow knowing what was about to happen, yet it was eclipsed by his desire for more. Crawling onto the mattress, discarding the bra, he positioned himself on all fours and waited. He could hear Night rummaging around in a drawer, but he couldn’t bring himself to see what what happening.
“Not going to take your panties off? I’d hate for them to get ruined,” Night called out from behind him.
Obediently, Shining acquiesced, shuffling in place as he pulled the undergarment from himself. With his lower half now bare, save for the stockings he had on, he awaited whatever fate would befall him. Fortunately, he wasn’t left wondering for long, as something warm buried itself between the ivory cheeks of his tush.
Stifling a yelp, he felt Night’s muzzle press into his rump, just before the large stallion’s tongue worked into his ass. The sensation was surprisingly pleasant, causing him to press back into his father’s face. Cadance and he had fooled around with toys before, yet that paled in comparison to being rimmed.
Just as he was beginning to truly enjoy the experience, it ceased; replaced by something cold being jammed into his backdoor. A cool feeling filled his interior, causing him to look back in time to see a bottle of lube being tossed to the side. As if that hadn’t cemented his suspicions, the imposing unicorn was shuffling onto the bed behind him, positioning himself to his rear.
“Come on, Honey, show off that sexy hole of yours,” Night purred, eyeing the femcolt’s succulent bottom.
Easing his chest to the bed, Shining reached back and pried his cheeks apart. He could hardly believe he was presenting himself so shamelessly, and to his own father no less! Still, he couldn’t deny how hot it was; obediently following another stallions orders, while all prettied up, had his heart pounding.
“Mmmmm, there we go,” Night groaned, sandwiching his meat between his boy’s buns. “Hope you’re ready…”
Clutching his cock, while the femcolt got back onto all fours, Night ground his tip through the cleft of Shining’s backside. Prodding the supple, well lubricated pucker nestled there, he grinned. Grabbing his son’s hip, he steadily began applying pressure. He wasn’t going to stop until…
“Oh buck,” Shining groaned, feeling the blunt head pop into himself.
Grasping the sheets, he grit his teeth, doing his damnedest to relax. Night Light was far larger than anything he’d ever played around with. Still, the exquisite feeling of warmth and fullness was unlike anything he’d ever experienced. Thankfully, his father gave him a moment to adjust, before slowly bucking his hips.
With a gentleness belying his size, the stallion steadily began thrusting into his son. Every plunge drove more of himself into the marish unicorn, as he drove himself deeper and deeper still. Before he knew it, his medial ring had bumped against Shining’s stretched hole.
The sensation of being filled, held by a large, dominant pony, spurred Shining to act. Honestly, he was amazed he’d been able to handle something that huge, yet he wasn’t satisfied. Rocking back, synchronizing their movements, he wanted more. Every plunge caused the thick, lower portion of his father’s stallionhood to grind against his entrance.
Nothing his son’s enthusiasm, Night obliged. Ramming his waist forward, undeterred by the resistance he met, he jammed the remainder of his length into Shining’s rear. Pulling the smaller unicorn to himself, he didn’t stop until he was fully hilted, leaving his pendulous nuts to rest against the lad’s coin-purse.
Shining’s eyes rolled to the back of his head, as the massive tool snaked into his colon. The only word to describe the feeling, of being so abjectly stuffed with cock, was intense. Looking down, past his braced arms, he noticed a slight bulge in his abdomen. He’d heard of such things before, but he’d never anticipated seeing something like it in person; let alone experiencing it first hand.
Despite the overwhelming sensation, his member was rock hard and dripping pre-cum to the bedsheets. Sure, it could have been the exhilaration of it all, or perhaps the fact that his prostate was being very vigorously crushed, but any discomfort was overshadowed by a growing pleasure and confidence within him. Slowly, he waggled his rump, pining for his father to continue.
Taking the not-so-subtle hint, Nightlight began hammering away. Unlike before, when he’d been taking his time, he enthusiastically pounded Shining’s ass. Shifting focus from the femcolt’s face to his behind, he watched his son’s pucker cling to his shaft with each backstroke. The sight, while captivating, caused his pace to quicken.
With his body being rocked by every titanic thrust, Shining struggled to maintain composure. His arms and legs felt weak, as a growing heat and pressure welled within him. It was almost as if an inferno of bliss had been ignited, threatening to overtake his senses. Still, he endured, pushing back to meet his father’s plunges.
“Mmmmph,” Night grunted. The speed and force of his movements gradually increased, eventually causing his girlish unicorn’s torso to collapse to the mattress. The time for subtleties had passed; if his son wanted to be treated like his mother, that’s exactly what he was going to get.
Biting down on the pillow beneath him, Shining muffled a rapturous scream. He felt release was imminent, although it was unlike anything he’d experienced before. The urge to cum was welling up within him, a mounting sensation of unstoppable pleasure, yet he wasn’t even touching himself. Bucking back to meet his dad’s thrusts, he felt the stallion shift.
Night Light shuffled forward, stepping over his son’s legs, before jackhammering into Shining. Wrapping his hands around the lad’s slim torso, he adjusted the angle of his plunges, causing his dick to directly impact the femcolt’s prostate. Every thrust was punctuated by his balls slapping against Shining’s lesser equipment.
The increased pressure on his p-spot, coupled with Night’s furious rutting, pushed Shining over the edge. A whorish, girlish moan escaped him, as his body was racked with uncontested bliss. His unmolested stallionhood weakly dribbled and slung spunk to the blankets, a testament to his submissive nature.
A loud groan above him was the only warning Shining got, before his father hilted him. He barely noticed the larger unicorn’s weight draped over his back, as a sublime heat surged into his interior. The influx was enough to raise his voice an octave, pushing his ecstasy to even greater heights.
As Night fitfully bucked his hips, jizz surged through his length. His weighty nuts disgorged pints of the hot, sticky substance, filling his son with his essence. Acting on impulse, Shining clamped down upon the stallionhood entombed in his depths, ensuring every drop of seed was deposited as deeply as possible.
The sensation of submitting, being held and used by a domineering stallion, was an eye opening experience. He could feel the weight of his father’s seed in his gut, hear the guttural, masculine grunts in his ear, taste the cloying and salty flavors of his father’s pre-cum, and smell the irresistible virile musk of his partner. To his horror, he realized he could quickly get addicted to it all.
Unable to control himself any longer, Shining crashed to the bed, with Night Light on top of him. Panting, drooling, and devastated by a pleasure he’d never known, his mind grappled with the situation. He’d been bred by his father, while adorned in his mom’s lingerie. Regardless of what happened in the future, there was no looking back.
Pushing himself up, Night rolled to the side. His softening stallionhood pulled free from the femcolt’s gaping ass, leaving the abused hole to weakly leak jizz to she sheets. Wiping sweat from his brow, he appraised his cum-drunk son.
“Glad you’ll be able to fill your mother’s shoes, when she’s not around,” he chuckled, slapping the boy’s backside.
Shivering, Shining turned to face his father. He didn’t know what to say, though the comment made him blush. Truth be told, he wouldn’t mind similar treatments in the future; that was, once he’d been given a chance to recuperate. Reaching back, feeling his swollen and tender hole, he suppressed a shudder.
Night Light really had done a number on him, and he was sure he’d be sore in the morning, though that’s not what had his father’s attention. Following his parent’s gaze, his eyes went wide. His belly was positively swollen, distended obscenely, almost as if he were pregnant. As he opened his mouth to speak, the large stallion silenced him with a kiss.
“Next time, if you want another load of foal batter, how about you take the initiative,” Night whispered, shooting his son a wink.
Giving a small nod, Shining cuddled up against his father. Now that a line had been crossed, a whole new world of possibilities lie before him. Velvet and Twilight weren’t going to be back for another two days, which meant he’d have more time to spend with his daddy…
