Flash Sentry flicked his ears and swished his tail. The mare—Sunset, that was her name—walked just in front of him. Her tail was slightly raised and Flash closed his eyes, sniffing the thick smell of her excitement and the pheromones of a just-passed estrus cycle. Their hoovesteps rang on the crystal floors and echoed down the hall.
"Quiet, you two," snarled the human from behind him. She, too, was named Sunset and clearly some sort of magical paradox of the mare. She also carried her boots in her hands and walked silently on the crystal floor with her fleshy feet. She crouched slightly to keep from banging her head on the corridor's ceiling. "Twilight or Trixie will hear!"
"Trixie's pretty good looking," Flash said. "I've got no problem with her joining us."
"Trixie's gay," said pony-Sunset. "No taste for alicorns?"
"I've fucked Twilight," Flash said. "She's boringly vanilla. Made me wear a condom and wouldn't let me fuck her ass. Something about getting stuck, coconut oil, and paramedics? We just sorta stopped seeing each other."
The two Sunsets looked at each other. "Then you're going to enjoy this," they said in harmony.
Pony-Sunset's horn flashed and popped the lock on one of the guest suites; they were on the second floor of Twilight's castle. She snuck in the door, medium-sneaky, and looked around. "Okay, it's empty."
Flash followed her in and then human-Sunset followed him and closed the door, dropping her boots by the door.
"I still don't understand," Flash said to the woman, "why you didn't become a pony when you took the mirror."
"High-proof ethanol?" she replied, pulling a flask from her jacket pocket.
"Where'd you get that?" Flash asked.
"My little brother," said pony-Sunset.
"Who?"
"Sunburst," she replied. "The only class he passed at Celestia's school was chemistry. Want some?"
Flash cocked his head. He was more of a beer and mareajuana type but a little help before a threesome might be nice. "Yeah."
The mare hopped onto the bed, circled around twice and then flopped onto her back, head on the pillows and underside pointed at the other two. She spread her hips wide, giving Flash and the woman an excellent view of her belly, erect nipples, throbbing clit, soaking wet labia, and clenching asshole.
Human-Sunset took a swig from the flask and then set it on a side table. She stripped off her leather jacket and hung it on a wall hook before peeling her pink tanktop off, over her head, exposing nicely firm breasts with large nipples about the same color as her hair. Flash trotted over and hopped up to his rear legs, forelegs planted on her thighs, and stretched his neck, unable to reach her breasts. He settled for kissing her belly button, making her giggle.
She grabbed him by the flanks and yanked him off his hooves. He flapped as she spun him a half turn, until she held him upside down at head height. "I keep forgetting how small you ponies are. And pegasi are even lighter than unicorns."
"I—" Flash started.
She lifted his sheath to her mouth and sucked over its opening, tonguing desperately, lips massaging, and Flash whinnied. Bending his spine, he planted his forehooves on her muscular abs and reached his neck, his lips clamping around her left nipple, suckling greedily and tonguing it. He gently bit it as the nipple hardened. Sunset gasped, a shudder running through her body, as pony-Sunset on the bed moaned with lust, rubbing her clit harder. Flash broke contact with a slurp and then latched onto her other nipple, sucking, tonguing, and biting as it, too, hardened. His engorging cock poked from his sheath and between the woman's lips. She bit ever so gently on his glans as Flash sucked harder on her nipple.
Human-Sunset lifted him, breaking his contact with her nipple and releasing his rapidly engorging cock with a slurp and let go, dropping him from her head height. Flash's wings flared for a soft landing. His cock was fully out of its sheath, hard and slapping his belly as he moved, his balls getting sore as blood rushed to his underside.
She shimmied her skirt down, letting it pool on the floor. The woman's snatch was just in front of his nose in all its interspecies glory. Thank Luna she didn't believe in underwear!
Her pubic hair, red and yellow like her mane, was trimmed short, little more than a stubble, but thick. He hopped to his rear legs and planted his forehooves on her thighs, letting his nose brush her trimmed bush, noticing it was peach-fuzz soft. He sniffed deeply, the scent of her excitement different from a pony's. He'd never been with a human before and her excitement tickled his nose and made his mouth water in a very different way. A pony pussy would have smelled stronger, but her scent was more complex.
He nuzzled a little lower and licked her labia, tasting her wetness. The liquid was thinner than a pony's, almost no texture or mouthfeel, but the taste was much stronger and sharper. Her clit hardened instantly against the top of his tongue. She put a hand in her mouth and bit a finger to keep silent.
"Go ahead and be loud," called the mare from the bed, where she rubbed her nipples and clit with her forehooves. "These walls are soundproof."
The woman moaned deeply and Flash dropped to all fours, stepped forward between her legs, her knees brushing his shoulders, and reached his head straight up so that he could get his lips around her clit. He sucked and tongued desperately and she slapped her palms flat against the crystal wall, fighting to stay standing. Her pussy throbbed and grew wetter under his tongue. He shifted his face and drove his tongue into her pussy and she came, screaming and shaking and a sudden rush of juices wetting his muzzle, soaking the fur on his snout.
Flash pulled back and flared his wings. "Nice. Ready for bed?"
The woman blinked at him, drops of pussy juice rolling down her inner thighs, her knees shaking. "Whoo. Yeah, okay."
She grabbed the flask from where she had dropped in, on a side table, and shakily walked to the bed. Pony-Sunset stopped masturbating and folded her forelegs behind her head, smiling saucily at the other two. The woman held the bottle down and Flash grabbed it in a wing, taking a solid swig. He coughed and gasped.
"Cadance lets you all drink on duty?" asked pony-Sunset, wriggling her butt and tail against the fine silk sheets.
"I'm off-duty, but yes. If you get caught, you have to share with her." He climbed onto the bed and buried his nose between pony-Sunset's thighs, licking between her labia. She moaned, flailed with her forelegs, and arched her back against the bed. The wetness from her masturbation, where she'd warmed herself up, flowed over his snout, mixing with the juices from eating the woman's snatch a moment before.
He buried his face deeper, sampling her taste. The mare and the woman, although the same 'person' from different dimensions or realities, tasted quite different. Her juices were much thicker than the human's, but the taste milder and more familiar to Flash—more typically pony. He brushed his thick, heavy tongue across her clit and then pushed up on his forelegs, looming over her abdomen. His cock pulsed and his balls hung low, throbbing and sore with excitement.
The mare levitated the flask of booze to her lips and took a large swig. She, too, coughed and gasped. "Ack! Strong." When she coughed, her pussy clenched cutely right in front of his nose and Flash buried his tongue back into her channel. Her back arched further and her coughs turned into moans.
His thick, throbbing erection got noticeably bigger, the flared tip of his cock pulsing painfully with every heartbeat and his balls clenched up tight to his underside.
He licked pony-Sunset's nipples, which were barely an inch above her vulva, swirling his tongue around the thin fur that covered them. Sunset moaned and squirmed as his tongue brushed her, the nipples turning hard and erect.
Human-Sunset grabbed Flash's cheeks in her hands and lifted his face, kissing him. He kissed back, the sensations strange and unfamiliar. Her mouth—her everything—was bigger than his, and her tongue wrapped around his, capturing it, pulling it into her mouth. Her sharp omnivore teeth scraped down his tongue and the danger of the sensation made his tail flag vertically and his balls clench.
She then leaned down and licked pony-Sunset's nipples, the pony bucking on the bed as those same sharp teeth clamped down on the erect nubs, and then buried her human face into the mare's snatch, slurping loudly.
Flash reached a wing and rubbed up-and-down his erection, feeling completely blue with the excitement and the booze.
With a sigh, human-Sunset flopped belly-down on the bed next to the pony version. She slowly spread her legs wide and folded her arms under her chin.
Flash blinked and licked his lips as human-Sunset's legs spread wide, exposing herself to him. The pussy lips were dark red, and the bright red hairs trailed up, around the lips, and then thinned as they faded up into her butt crack. Pony-Sunset leaned up, on one elbow, and her horn lit, the aura gently spreading human-Sunset's butt wide and Flash whimpered as the human's asshole was revealed to him, tight and inviting and with a few thin, long red hairs surrounding it.
The mare rolled over and positioned herself next to the human, head-down/ass-up, tail raised and swishing.The human then raised herself, up on her knees and elbows, wiggling her ass since she didn't have a tail to wag.
Flash stared at them for a moment, his brain adjusting. Pony-Sunset was about as tall as human-Sunset's knees when they stood, and probably weighed... an eighth as much? Seeing them, next to each other, really brought the size difference home. Flash had an enormous cock by pony standards—pony-Sunset would be sore tomorrow, her cervix bruised, and that was just a fact—but he was concerned he might not be up to the human's expectations.
Well, there was nothing to do but to do them and hope for the best. He climbed up onto the pony and wrapped his forelegs around her flanks. "Hey, your fur is really soft."
"Thanks, I conditioned it this morning." She wiggled her rump backwards and brushed the tip of his cock with her sopping-wet labia. Turning his head to see, he lined up and shuffled his rear hooves forward, spearing her pussy and driving in.
The mare gasped and whinnied as her tight, hot, wet snatch spread wide as Flash's huge shaft—huge by pony standards, he reminded himself—split her open. He bent down, bit her ear, and slammed his hips forward, hilting her fully and slamming into the bottom of her womb like Rainbow Dash slamming into a cliff face.
"OOF!" she said. He channel clenched around him, her hot excitement soaking the soft fuzz on his ballsack. He squeezed tighter around her hips with his forelegs.
A strange sensation tickled his balls and Flash yelped and looked down.
The woman's fingers were fondling him, long fingernails scratching furrows in the fuzz soaked by the mare's pussy juice. She rolled his left ball between her thumb and forefingers, then his right. "Oh!" Flash said. "That feels good."
Her fingers moved to pony-Sunset's clit and rubbed, clockwise then counter, gently brushing the underside of Flash's cock.
With another whinny, Flash pulled back, stroking out, and pony-Sunset's pussy spasmed around his shaft. As soon as his tip got to her entrance he slammed back in, hard, and she gasped. He built a rhythm, slow out, hard in, and human-Sunset's fingers joined them, rubbing harder on the mare's clit as Flash slammed in and brushing her clit more gently as Flash pulled back.
Pony-Sunset's horn sparked and her pussy gushed, squirting over human-Sunset's fingers; she clamped down on Flash, squeezing his cock hard as she moaned low in her throat. The heat of her soft channel called to him, tempting him to switch to quick, sharp thrusts and cum with her, but he fought the temptation and pulled out, pushing up with his forelegs, and popping out of the mare's pussy with a schluurp.
As Flash dropped back to the bed and sidestepped to human-Sunset, the woman put her fingers in her mouth and sucked the mare's emissions off them. Pony-Sunset squirmed forward and stretched her neck, kissing the fingers and then the woman's mouth.
Flash stood on his rear legs, forelegs planted onto the woman's buttcheeks, but he was too short. The tip of his cock barely poked her pubic bush.
Flapping, he leaped up and landed on her, belly on her buttcheeks and his chest aligned along her lower spine. His forelegs wrapped around her love handles and he wriggled, trying to find her pussy with his throbbing, already-soaked member.
He wriggled up, down, left, and then his tip found the wet, hot entrance to her. He pushed forward, flapping, gripping her sides to avoid falling off her butt.
Human-Sunset laughed. "This isn't working, is it?"
Flash pushed in, hilting himself. Velvety and warm, dripping wet, she surrounded him and he closed his eyes, luxuriating in the unusual sensation. Similar to a mare's pussy, but different, too. Maybe not as warm, but softer, certainly, and much wetter.
He pulled his hips back, balancing carefully and squeezing on her sides, his shaft retracting—
—he fell off with a yelp and landed on his back, wet and dripping cock pointing at the ceiling.
"Nope," human-Sunset said with a laugh, "Not quite working." She lowered herself to the bed again, belly-down and legs spread wide. Flash flipped to his hooves, a blush on his cheeks, and approached her, laying his belly on her buttcheeks and straddling her with his legs, his rear knees now on the bedsheets. That gave his cock a slight downward angle at her pussy and he pushed back in.
Pony-Sunset turned and reached a forehoof, turning Flash's face toward her and giving him a deep kiss, her tongue probing into his mouth as he pushed his cock back into the woman's channel. Her pussy gave squelchy noises as he thrusted.
Pony-Sunset broke her kiss. "Flash?"
"Yeah?" He slammed hard into the woman, and she gave an appreciative hmmmm.
"Butts."
"What?"
The mare turned around, raised her rump, and lifted her tail. "Fuck my butt, then hers."
"What?"
"That's a good idea," said human-Sunset. "Bless your heart, Flash, but, uh, our bodies aren't exactly to the same scale. You'll fit my butt better."
Flash whinnied, embarrassed.
The woman's fingers reached up and slipped into the mare's pussy. Pony-Sunset gasped, her forelegs kneading the bedsheets as her pussy clenched and asshole throbbed. Flash licked his lips, pulled out of human-Sunset's pussy, and took a few shaky steps to re-mount pony-Sunset. Flash looked at human-Sunset. "A little help?"
She pulled her fingers—actually, no, one finger was all she seemed to be able to fit—from the mare's vagina and grabbed Flash's tip, aiming it as Flash inched forward. She positioned his tip precisely in the center of the mare's tightly puckered anus and he slowly pressed forward.
"Gaaaah...." gasped pony-Sunset. Human-Sunset went back to fingering her, rapidly, and Flash closed his eyes to enjoy the sensation of her pulsing tightness fighting his throbbing shaft. He was slick, absolutely soaked, with their two pussies' mixed juices and that lubed him well enough. Pony-Sunset's ass gave way and his tip popped in, the mare cursing under her breath, and Flash's ego was a little restored. He might be small for a human, but by pony standards his cock was absolutely dinosauric, as pony-Sunset's discomfort confirmed.
"Sorry," he said, and pressed deeper.
"Oh fuck yeah!" said pony-Sunset. Now that he was in, she clenched on him and arched her back, panting heavily. "That's better. Fuck me, but don't cum in me. Cum in her." She tilted her head, pointing her horn.
Flash pushed deep, fully hilting, and balls slapping into her labia. Human-Sunset's fingers, damp with pussy juice, massaged his balls. The tight ring of pony-Sunset's anus clamped hard around the base of his cock and then he pulled back, her insides tight and hot around his tip, the sensation even better than when he'd been in her pussy a few minutes before. He withdrew until his flared tip caught on the inside of her anus, stretching her, pulling the muscular ring taut, and he pushed back in.
Pony-Sunset screamed, clenching on him, and hot pussy juice squirted across his balls and human-Sunset's hand. She lifted her hand to her mouth and licked the thick, glistening mare juice, then offered to hand to the mare, who sucked human-Sunset's hand clean, tasting her own emissions, her ass clamping even harder on Flash as she tasted herself.
Flash pumped twice more before his balls clenched up tight to his underside and the tip of his cock began tingling. "Sunset?"
"Yes?" they both said.
"Uh, you," he said, patting the human's butt with a wing. "I need to switch before I cum."
"Awesome," she said. She settled flat onto the bed, chest and belly down, hands folded under her chin, legs straight and together. She sucked her right index finger, which had been in the other Sunset's vag.
Flash's forelegs pushed up on pony-Sunset's ribs and she gasped in pain as his flare—excited, engorged, bigger than usual—was forced back out of her tight asshole. He popped free, his erection swinging free under his belly.
"Ow!" Pony-Sunset looked over her shoulder at him. "Need help?"
"Fair's fair," human-Sunset replied with a grin. "I put him in you."
Flash sidestepped, straddling over the prone human, and lowered his chest to touch her back, his chin resting just below her shoulder blades. Good Luna, he thought, we really are small compared to them. Pony-Sunset's horn lit and the soft tingle of her aura clenched around his shaft, the magic tingling in the smeared mixture of bodily fluids that coated him. She guided it and he lowered his hips a little until his tip pressed into something soft, taut, and warm. A few fine hairs tickled his tip.
"Yeahhhhh..." whispered human-Sunset, her voice rumbling under him. Flash wriggled his body, settling his weight more onto her. Her back was smooth, soft, warm, more than he imagined. He'd fucked ponies and griffons before, even dated a mule in high school (that was where he learned to bite mares' ears while he fucked—mules loved that), but he'd never fucked a species with bare skin instead of fur before.
It... was nice. He nuzzled his nose into her spine. She giggled and he thrusted forward, popping through her asshole and in.
The giggle turned into a moan. "Ah! Just the perfect size."
Flash pressed in farther, hilting, until his hips rested on her buttcheeks. Holding still for a moment, he just enjoyed the wash of sensations that rolled over him. Her smooth skin and muscular body beneath him, he squeezed on her ribs with his forelegs. Her buttcheeks pressed into the insides of his thighs, her tight anus clenching the base of his cock and her warm, soft ass surrounded his shaft where he drove deep inside her.
Pony-Sunset inched forward on the bed and nibbled at the base of his right wing, gently, delicately, and Flash unfolded his wings, spreading them over the bed. "You—that's nice."
"I've dated pegasi before," she said, then nibbled up the fore-edge of the wing, toward the alula, and the sensations ran down into his body, making the fur on his spine stand on end and all his feathers poof out. His cock throbbed from the erotic sensation and human-Sunset gasped as he stretched out her insides.
Flash loved having his wings nibbled, and he'd never before encountered a unicorn who knew how!
He pressed forward a little more, trying to get further penetration into the woman's ass, and she spread her back legs a few inches. His balls, still heavy with excitement, dropped down, between her thighs. The warmth of her body surrounding that most sensitive part of his body washed over him.
With a short thrust, he lifted his hips and then pressed back down, then again and again, settling into a quick rhythm, only pulling out a quarter of the way or so with each thrust, until his medial ring caught the inside of her anus, before pressing back in. Human-Sunset grabbed a pillow and bit into it, muffling her shouts.
Human-Sunset came, the assgasm rippling up her body from her butt, along her spine, and Flash felt it where his belly and chest pressed down on her. Her anus squeezed, a sharp pain around the base of his shaft, and her pussy squirted all over his balls. Pony-Sunset bit Flash's wing, right on the alula, and the combination of the wing-stimulation and the assgasm clamping around his cock drove him over the edge.
With a whinny, he bit human-Sunset, on her ribs, pinching a large fold of her skin between his teeth as he made a final thrust, the deepest yet, as far up her ass as he could get his cock, and he unloaded, his feathers all standing straight up and his tail flapping and his balls clenching tight up to his belly and as his cock flared deep inside her, stretching her anus and her insides, human-Sunset dropped the pillow from her teeth and screamed in pain that quickly turned to a moan as her assgasm returned and redoubled, her anus and insides clamping even tighter around him.
Thrusting twice more, short, sharp spasms of his hips accompanied by a gasped "Luna!" Flash finished, his balls emptying inside the human's ass.
Pony-Sunset bit harder on his wing and then let go, nibbling his ear and then shifting to kiss human-Sunset's lips.
"Wow," Flash said. "That was—thanks, you two."
"Our pleasure," they said in unison.
Flash sniffed. "What do we tell Spike about the bedsheets? This is going to be some toxic laundry. We should have put a towel down."
Pony-Sunset's horn flashed and they all were teleported to the en suite bathroom, lying flat on the heated tile floor instead of the bed. Flash blinked and flicked his ears, recovering from the teleport, and lifted his hips until his softening cock popped out of the human's anus with a schloop and a gush of mixed fluids.
"We take a shower," pony-Sunset said, "then I teleport us the Tartarus out of here, and Spike probably blames Starlight and Sunburst for the laundry."
