> Dash's New Outfit
> --------------------------------------------------------------------------

Something that never ceases to amaze me is just how quietly a pony can move, when she's determined to sneak up on you. How can hooves on a hardwood floor be so silent? It's uncanny.

So, I was sitting there, at my desk, working on my computer, when suddenly Dash's forehooves were on my shoulders and her wings were covering my eyes.

"Will? Don't turn around," she said.

I lowered my hands from the keyboard to my chair's armrests. Her feathers tickled my face and my nose itched. "I'm going to sneeze into your feathers."

Her wings pulled back from my face. "Don't look. Face forward." Wind ruffled my hair as she flapped once, dropping back to the floor.

I rubbed my nose.

"I've been looking at human pronography," Dash said. "It's kinda gross."

"It can be," I agreed. "Sometimes."

"What I like..." she said, "what I like are human workout magazines. Shape. Strong. Or Women's Health. Their 'tone your butt in ten minutes a day' workouts won't mean much for a pony—"

"Your butt is pretty toned already," I said.

"Very. The workouts don't mean much for me, but I've been looking at the pictures. Some of those mares... eh, women... in those magazines look really nice."

Where was she going with this? Was Dash annoyed by my working from home, trying to distract me? I didn't usually work on the weekends, and I had apologized to her before firing up my laptop. However, Michael, our ambassador in Canterlot, had emailed me last-thing Friday afternoon. A Deputy Assistant Undersecretary of something-or-other was coming to Ponyville next week and I needed to get her agenda finalized today.

Let's see, what had Dash said after I told her I needed to work? ...I'm going to Rarity's shop for a while.

Rarity's shop. Huh. I tried to see Dash's reflection in my monitor, but she stood directly behind me. 

"I was saying, 'The women in those workout magazines look really nice,'" Dash said.

I sniffed. She had been exercising—no surprise, this is Rainbow Dash we're talking about—and I smelled a hint of sweat. "Yes, they do."

"Their outfits n' stuff, right?"

I nodded. "Yeah."

"Do you humans think about anything besides sex?"

"Says the mare whose goal is 'twenty percent more creampies than Sugarcube Corner.'"

Dash chuckled. "Humans think about sex, ponies just have it. What I'm saying is, anything on TV or in a magazine or whatever, anything you humans do, is about sex, because your whole species needs to chillax. So I got to thinking about the outfits those women in the workout magazines are wearing."

Ohhhhhhhh, my brain said. She'd been at Rarity's, and now she was talking about outfits.... Certain parts of my body were beginning to show a physiological response that resulted in my sweatpants feeling smaller than they had felt a moment before.

"The magazine outfits might be practical for working out, but their designs are meant to be sexy, too, right?"

"...right," I said.

"So I took those magazines to Rarity, right? And I asked her what a pony would look like in that sort of outfit."

I was now throbbing. I pulled out the drawer my computer's keyboard was in, trying to conceal the pup-tent in my sweats. I also glanced at my laptop and verified the little sticky note still covered its webcam.

"You men... you like that stuff, right? The shorty-shorts, the sports bras, the athletic women lifting weights or doing squats?"

"Well, yeah," I said. "Although I'm on Team Pegasus now."

"I took a lap around Ponyville in my new outfit," Dash said. "Running, not flying. I got some weird looks from the ponies, but the men I saw all stopped and stared."

I moved my right hand from the armrest of my chair and rearranged my cock. It was getting bound up in my boxers.

Her forehooves weighed on my shoulders again,  and her teeth nibbled the back of my neck. A chill ran down my spine and goosebumps rippled down my back as I squirmed in my chair.

"Close your eyes," she said.

With my eyes closed, I turned my head. Her lips met mine. She tasted good, with that tiny hint of fresh citrus that pony lips always seemed to carry, but was especially strong with her. Her tongue snaked out and found mine and pulled it into her mouth, sucking ever-so-gently. She turned my chair around until I faced her—my eyes were still closed, I was behaving—and she put her forehooves onto my thighs.

Our kiss broke. "Nice," I said. "When are you going to let me open my eyes?"

She rubbed a forehoof against my crotch, underneath my hard-on, massaging my balls gently through the fabric. "You humans and your clothes. You all have the least sex of any intelligent species."

"Who says we're intelligent?"

"Keep your eyes shut." She grabbed my right hand with her teeth and tugged. I stood, and she guided me out of my office. The left turn meant we were headed to our bedroom.

Her tail brushed the crotch of my sweatpants as we walked.

"You're teasing me," I said.

"You haven't seen teasing yet," she said, releasing my hand. "Watch the doorjamb."

I tucked my left elbow in just in time. 

My erection stood out horizontally, throbbing against my sweats where it poked through the fly of my boxer shorts.

"Hmmmm," Dash said, and nibbled on the tip of my cock through the fabric.

"You're being very distracting," I said with a pant. 

Her hooves slid under the tail of my t-shirt, tickling my flanks just above my waistband, and she shimmied my pants and boxers down to my ankles. 

For a few seconds, nothing happened. My hardon throbbed, forlorn, in the warm air of our bedroom as I just stood there with my eyes closed.

Then a warm, wet tongue ran up from my knee, along the inside of my right thigh, up to my balls, and she took my balls into her mouth as her velvety-soft nose rubbed the underside of my cock.

I moaned, low in my throat, and reached out with my left hand, catching the edge of my dresser to steady myself. My head went light and my heart raced as her hot tongue and soft lips massaged me, her downy cheeks brushing the insides of my thighs...

My right hand moved down and found the top of her head. I scratched behind her ears and she let out a moan of her own, vibrating my balls as her tongue and lips pressed my balls against each other, then she burrowed her tongue up in between my balls for a moment...

With a wet slurp and a pop, she released me. "Okay, one more second..."

"Dash, you're killing me here."

I heard a rustle of sheets as she climbed up onto our bed.

For a moment—nothing.

Then: "Okay, Will, open your eyes."

I opened my eyes.

Wow.

Wow.

"Wow," I said.

Dash sat on our bed, her right side toward me. She splayed her hips, her tail tossed to her left, her forehooves planted between her rear legs.

She looked over her shoulder, giving me a half smile. "Ya like it?"

"Rarity's a genius." Human and pony fashions almost never translate back and forth—but that clothes horse is the one who has the skill to make it work.

"If I tell Rarity you said that, she'll want a threesome with you."

"Then tell her I said she's a genius," I replied.

"Maybe for Rarity's birthday next month?"

"Find an earth pony, and we'll have the trifecta."

She chuckled. "We'll start with just Rarity. Pinkie's already sent two humans home to Earth on medevacs."

Dash wore a midnight-blue workout ensemble, with electric-yellow seams and highlights. The shorts conformed perfectly to her toned ass, showing the rippling of her muscles though its fabric, and a hint—just a hint—at the outline of her naughty bits.

Around her upper body was—well, what to call it? On a human it would have been a sports bra, but a pony's teats are on the complete opposite side of her torso from this whatever-it-was.

I'll call it a sports bra for the sake of convenience. Its sleek lines, dark midnight blue with bright yellow highlights, gave her an appearance that left my heart racing. My erection throbbed even harder, the hot blood filling it, and the wetness from her mouth and tongue cooling the underside of my ballsack and cock.

She pushed her shoulders up, arching her back and flaring her wings like some sort of angel from on high. "You like it?"

"Oh my God," I said. 

"I'll tell Rarity you think she's divine," Dash said with a smile, "and you'll definitely get that threesome."

Dash and I had fucked Rarity before, and it had been wonderful... "You and she thought of this outfit?"

"Well... Spitfire is looking at doing a charity Wonderbolts calendar again. But last year's one sold so badly on Earth we lost money."

"I told you that with the Wonderbolts' balls and labia hanging out, it would only sell at specialty shops, and people wouldn't be allowed to hang them at work. Thunderlane's cock was out of its sheath on the cover."

"But he has such a small cock, none of us thought... your species is so weird. Anyway. Seeing your reaction," she pointed her snout at my boner, "I think we have a plan for this year's calendar. Spandexbolts."

"Your flight suits are spandex."

"Yeah, but the flight suits are anti-sexy. Here, come try this out."

I wriggled out of my shoes, socks, and clothes and took a running jump. My weight hit the bed and the mattress bounced her into the air. Dash is pretty muscular and heavily built by pony standards, but she's less than a third my size, roughly the size of a small golden retriever or a large border collie. 

She angled her wings and landed on me, knocking me down to my back and squatting over me. I relaxed onto the bed, hands behind my head, and she gave me a kiss. I hadn't shaved that morning, so I had just a hint of beard, and it prickled as she rubbed her softly furred cheek against my cheek.

"Love you," she said with another peck on my lips.

"Love you," I said, reaching up with both hands to scratch her ears.

She closed her eyes and stretched her neck like a cat, twisting her head left and right to get the maximum possible ear-scritches.

I lifted my head up, kissed her on the forehead, and then bit her left ear. She squealed and shuddered in delight, saying, "Okay okay wow stop that's too good."

Staring into my eyes, she lowered her hips and the smooth fabric of her shorts pressed down on me, capturing my cock between our bellies, and her tail reached down, its hairs lightly tickling my ballsack. 

"I love that," I said, as her tail massaged my balls.

She kissed me again, and began grinding the crotch of her shorts against my balls and the base of my shaft. I nibbled her lip to keep myself from panting. The spandex wasn't perfectly smooth, so it prickled just a little, but I was popping an even harder erection. She was damp, too, her excitement already soaking through the fabric.

Another sensation, a cool tingle, slowly seeped into my ballsack, my balls, into my belly at the base of my— 

"I'm feeling magic," I said, breaking the kiss. Any human who's been in Equestria more than a few days knows the cold-hot tingle, kind of like a menthol cream, of magic on skin. When the spell is right on your balls and cock while you're in bed with a mare—it's pretty unmistakable.

"I'm on my cycle," she said.

"Ohhhhhh..." I said, and my eyes went wide with delight.

Estrus doesn't make mares any hornier than usual. Let's be honest, ponies are way hornier than humans any day of the year. However, mares of all three tribes found themselves with two spells manifesting during their heat. The first spell, which she has no control over whatsoever, is that any set of male genitals that get in close proximity to her genitals are going to find themselves supercharged for an hour or two. (This is why crowded trolley cars or trains are such a gamble in Manehattan or Canterlot.)

"Happy to hear that?" She kissed my nose and then flopped over, off me, onto her back. Dash tucked her wings tight to her sides and pulled her forelegs up, forehooves to her chest, and spread her hips wide. "Still like my outfit?"

"It's amazing," I said, sitting up and moving to kneel down between her rear legs. Her tail snaked out, under me, and twitched up to tickle the small of my back.

I bent down and kissed the inside of her right leg, holding it with both hands, massaging, licking, and maybe biting just a little bit. She squirmed as I hit the spot on the back of her knee, her tail thrashing left and right across the bedsheets, slapping my knees left-right-left-right.

"More teeth," she said, and I nibbled harder. She gasped and jerked on the bed.

My lips slid down the inside of her thigh, kissing, and the smell of her musk and sweat increased. It wasn't a strong smell, just a hint, but she was certainly in the early stages, probably the very first day, of her heat cycle.

Oh my, oh my, this was going to be a long week. A good week, but a long one!

"Please..." she said. "Please..."

I scooted back, going belly-down on the bed and trapping her tail under my chest as my lips reached the point where her bare leg met the shorts. I ran my tongue a few inches along the hem. She shivered and made a little squeak.

Moving to the crotch of the shorts, I closed my mouth and rubbed my lips and nose against the moist spandex, massaging her pussy through her clothes.

"Please!" she shouted, arching her back and flapping her wings against the bedsheets. "Please get those shorts off!"

I tugged on the waistband, but she reached down with a forehoof and touched the back of my hand. "Tail first. Don't want a sprain."

I nodded.

Dash kicked up her rear legs and grabbed her knees with her forehooves, levering her butt up off the sheets. I reached under the waistband, into the shorts, and grabbed a handful of her ass and squeezed.

"You're distracted," she said.

I gently pulled her tail through the hole. The waistband loosened once her tail was free, and I shimmied the shorts off her butt and up her legs, and tossed them on the floor.

She smiled up at me and spread her hips wide. 

I closed my eyes and inhaled, enjoying the scent of excited mare and the beginnings of her estrus cycle. Her pheremones had no biological effect on me—two completely different planets' evolutionary trees, after all—but I remembered the few other times she'd gone into heat since we got together, and the scent left my mouth watering and my cock throbbing, Pavlovian conditioning where I remembered how amazing the sex would be.

"Look carefully," she said.

I opened my eyes and looked down.

It was blue, almost the same color as her coat. That was why I hadn't noticed it right away.

"Does it vibrate?" I asked.

She grinned.

I reached down and pressed the button on the back of the buttplug, and it started buzzing as its internal vibrator kicked on.

"Yes!" Dash gasped, arching her back, spreading her hips wide, and wriggling against the bed. As she spread her hips, her toned butt flexed right in front of me, the hard muscles so inviting...

I placed a hand over her pubic mound and smiled. The vibration traveled through her nether regions with enough strength to feel in my palm. 

"William?" Dash said, still squirming her spine against the bedsheets, her wings limp, "are you going to use those fingers or not?"

My hand moved down, from her mound, and covered her slit. The blue fur on either side of her inviting pink opening tickled my palm. Her clit, red and engorged, winked against my middle finger.

I slid my ring finger into her, and her warmth shocked me. Pony pussy is always warm compared to a woman, but this was insane. Dash was practically boiling.

"Ahhhhhh..." she said. Just my ring finger was as much as she could take, at first, given how small ponies are compared to humans. "Yeah."

With my other hand, I rubbed her clit, trying to warm her up even more, get her relaxed enough that I could get a second finger in, before I dared try to mount her.

Her chest heaved and her eyes squinched shut as her tight pussy clamped down again and again on my finger. The spandex of the sports bra was so tight I could see her flight muscles flexing through the fabric as her wings pressed against the bed.

I switched hands, putting the ring and pinky fingers of my right hand into her and lifting my soaking wet finger to my mouth. I sucked off her juices and made an mmmmmmm sound. The strength of her taste was amazing, even on the first day of her estrus. Strong, her usual honeysuckle taste overlaid with something like agave and blackcurrant.

Her eyes popped open and she looked up at my face, then opened her mouth and stuck out her tongue. I leaned down and kissed her, our tongues intertwining, and she sucked her own juices off my tongue and lips.

"More!"

I pulled my fingers from her pussy and offered them to her. She lifted her head up and sucked my fingers, getting every drop of her juices from me, tongue massaging my fingers, in between them, sucking them into her mouth, cleaning off every drop of her own taste, then she flopped back, flat on the bed, eyes closing again as she panted.

"Please," she said. "Now!"

I rubbed her ribs with both my hands, up and down the fabric, massaging the huge muscle groups just beneath her wings. She melted, relaxing into the bed with a sigh and a shudder. 

"Oh, wow... yeah..." she whispered.

I scooted my knees forward until the tip of my cock just touched her lips. The short blue fur tickled my own opening and a shiver ran up my spine as my balls clenched tight against my underside. God, she was soft! Her pubic fur was unlike anything else I'd felt in my life.

Still massaging her ribs with my left hand, I used my right hand to grab my shaft and rubbed its tip up and down her clit. She squealed and her first gush emerged, wetness slicking her folds, running over the buttplug, soaking the top of her tail, and she jerked her hips forward, trying to capture my shaft, but I shifted my weight back just enough to prevent her.

Her pussygush carried more of her magic, that estrus-supercharge, and my dick tingled, almost burning with the sensation. A soft aura, the same blue color of her coat, suffused around both our naughty bits like St. Elmo's Fire. I smeared my hand over her pussylips to collect her juices to smear over my ballsack. The tingle felt like dipping my balls in Tabasco, but I knew it would be worth it when I finally came.

And it left the soft blue glow around my balls. I officially had magically blue balls.

And I loved it.

Dash's back arched and she keened, a high-pitched squeal, as I pressed my tip firmly against her clit again. The buttplug's vibrations came through her clit and into my tip, which, mixed with her wetness and the forceful winking of her clit, made my eyes cross.

"Don't stop don't stop don't stop don't stop..." she begged.

I stopped, pulling my shaft up an inch, away from her.

"I said don't stop!"

I smiled at her. She glared at me.

Placing my hands on the bed, I stretched out, lying down on my belly and trapping her tail under my chest again. I lowered my face to her snatch and inhaled, enjoying the flowery-cinnamony scent of pony pussy.

"Willllliaaaaammm..."

I also sensed another smell, one that I vaguely recognized... "Was Fluttershy at Rarity's shop?"

"Yeah, she offered to warm me up for you."

I just chuckled. Explaining monogamy to a pony was like explaining quantum field theory to a diamond dog. Besides, Fluttershy and Dash had been friends, and friends with benefits, since they were young enough to make any human... uncomfortable... to think about. Dash came home to me every night, and that was enough.

I brushed my tongue along the outside of her pussylips, through the soft downy blue fuzz, and her whole body jerked. "I'm surprised Rarity didn't help, too," I said.

"Rarity put the buttplug in. Stop teasing me!"

Continuing to tease her, I circled my tongue up, just past her clit, and down the other side. Vibrations ran up my tongue, the buttplug still buzzing merrily. I let my breath play across her slit, and my right hand played with the long hairs of her tail, which flopped weakly under my chest. My left hand snaked forward and three fingers entered her...

"Yessss..." she hissed. "Oh Luna..." 

Her channel was hot, almost scalding. A pony's normal body temperature would have been a deadly fever for a human, and it seemed like all of that heat was pouring into my fingers. Her wetness, her magic, and the vibrations all combined to make a wonderful feeling. 

"Please..." she squirmed more, slithering on the bed, almost bucking from side to side. Her wings stretched to their full span, pinions hanging off either side of the bed. "Please!"

Removing my fingers from her canal, I reached that hand up and offered it to her. She sucked the fingers into her mouth, getting her juices again, and I reached out with my tongue, splitting her pussylips open and finally thrusting my tongue into her.

Oh, the heat! The taste! It was like drinking warm honey, with perhaps a hint of mulling spices. So strange that it seemed so similar, and simultaneously so different, from the women I'd bedded before I moved to Equestria.

Dash's squirming increased. She reached down, grabbed my head between her forehooves, pushed it firmly against her snatch, and she started twisting her hips up-and-down, rubbing against me. My lips brushed up and down her pussylips, my tongue along her opening and to her clit and back down as she ground against me, the buttplug's back bumping my chin and I got a momentary accidental taste of silicone rubber. I could hardly breathe, gasping small bits of air as her pubic mound covered and uncovered my nose, but trembling in her hips and her powerful muscles joined the vibration of the buttplug and she pushed my face even deeper against her pussy, her juices flowing and filling my mouth as I just held my breath, swallowing her flow to avoid drowning, the magic burning wonderfully down my throat with her thick honeysuckle flow, as she shook and bucked against my face. She screamed, a loud keen, and threw her forelegs up, over her head, and collapsed against the bed as her orgasm passed.

I pulled my head back an inch, took two desperately needed breaths, and then ran my tongue from the very bottom of her slit, across the opening to her channel, to her clit, and then stopped.

Her chest heaved, every muscle and rib defined even through the midnight-blue fabric of the spandex sport bra, and her eyes opened and slowly focused on me.

"That—" she panted "—that was amazing."

"More?"

"No, I think I might die. Let me fuck you."

I was about to say, Doggystyle? before I caught myself. Although ponies loved that position, calling it 'doggystyle' was a sure way to spend the night on the couch. "From behind?" I asked.

"Tartarus, no. Flat on your back."

I did a pushup, releasing her tail from under me, and wriggled up until I was looming over her, my hands on either side of her shoulders. 

I carefully kept my weight on my hands and knees, not on her. Missionary position was an absolute no-go—I outweighed her more than three-to-one, and we had agreed to never, ever try it a second time. She kissed me, licking the flows of her orgasm off my lips and cheeks and chin. 

"Pull your wings in," I said, kissing her forehead, and then I flopped over to the left side of the bed when her wing was clear.

She got up on her haunches and looked down at herself. "I'm sopping wet. We should have grabbed a towel before we got busy."

"We'll change the sheets later."

Dash hiked up a leg and straddled me, lowering herself. She deliberately missed my cock—which, by that point, was hard enough to hammer nails with—and sat across my thighs. She weighed almost nothing, compared to a woman, and she rested gently across me, her dripping wetness pressed against my balls, and her fluffy pubic mound pressing against the underside of my erection.

That felt... wow. Every part of her body is wonderfully soft, her coat smoother and softer than any puppy or kitten on Earth, but her pubic fluff was by far the softest spot anywhere on her body.

And it rubbed against my cock like a wonderful, warm blanket. Even silk wasn't that soft.

The protruding end of her buttplug pressed against my ballsack, its vibration driving a soft tingle up through my balls and into me.

"Wow," I said.

"I love fingers," she said. "That was really good. Ready?"

"Yeah. Are you?"

She frowned, slightly. I knew why: even an average human cock was extremely large by pony standards, and I am not, shall we say, merely average. She loved sex, she loved me, but no matter how much we fucked, it always took her some effort to get me in.

Lifting up, her forehooves on my ribs for balance, she flared her wings and flagged her tail as she situated her pussylips just against my tip.

My goodness, that sight! This wonderful, beautiful creature, all muscle and horny energy, looming over me, her wings spread in their fullness, the midnight blue of her outfit complementing the light blue of her coat, rainbow mane a bounty of color, and the bright pink of her marehood just touching my own manhood. It was a sight I could have enjoyed for eternity.

Still frowning slightly, she lowered herself. "Don't buck," she said. "I'm still loosening up."

I gasped and my eyes watered. Her pussy was hot like live coals, but it felt so good. The buttplug's vibrations surrounded me, massaging my cock from every direction, and I felt my own orgasm in its earliest beginnings.  

My gosh, I thought I had felt her magic before, but as her juices, simply overflowing with her mare magic, soaked into my skin, everything seemed so hot and cold together, the prickly-tingly sensation like when you foot falls asleep, and the magic flowed in waves down my cock, into my belly and my balls, a pressure building in my prostate, the magic storing itself for when she would finally let me cum.

She lowered herself about halfway down my cock when I bumped into the end of her channel, poking against the opening to her womb.

"You humans," she said. Dash relaxed her legs just a tiny bit more, trying to force herself down, force me up deeper, but she simply gave a little gasp as my tip pressed hard against her. "Ow. Okay, ready?"

"I've been ready for a while, Dash."

She smiled at me, and lifted herself up. She moaned forlornly and squinched her eyes shut as my length receded from her. She dropped her hips again, slowly, and her wings flared out even farther, fully erect, as I refilled her and slammed into her cervix again.

"Yes..." she said, sweat sliding down her forehead and rolling off her nose. The drop hit my belly, just above the navel.

That sensation! Her pussy was just as tight as ever, clamping down so hard on my cock it almost hurt, but so wet I slid in and out of her wonderfully, smoothly, slickly. She rutted me, up and down, keeping her strokes careful and not too deep. The wet hot slickness buzzed around me as her buttplug kept up its steady droning.

We stared into each other's eyes, and I took her forehooves into my hands, helping her balance as she slid up and down my cock. She started to tremble, her whole body shaking, as she rose toward another orgasm. He tail lowered and began to stroke left-right-left-right across my legs, a pleasant tickle of soft hair against my skin.

"Okay," she said, lowering herself fully, her weight uncomfortable on my cock, bending my shaft slightly, as I pressed too deeply into her tiny pony pussy. "Okay, you feeling good? I can tell my magic is working on you."

"Yeah, feels great."

"I can—can I—the second spell?" she asked.

Like I said earlier: a mare in heat has two spells. The first, unconscious and involuntary, will supercharge any male genitals she gets close to, and I could feel that magical gift suffusing every bit of me.

The second spell a mare gains is one she uses voluntarily—but Equestrian law and custom requires she get a verbal okay from her partner, because once the spell is in play, there's no changing his mind. He's in her until the end.

"Please," I said. "Do it."

She smiled, closed her eyes, and tilted her head. Her ears flattened as she called on the magic deep in her belly, gathering the magic toward where my cock touched the opening to her womb.

Even more warmth than before seemed to penetrate into the skin of my tip and shaft, into the hardness.

I gasped and arched my back as I felt the soft tug, right at the very tip of my cock, as the spell slowly opened the entrance to her womb for me. The muscles deep in her channel grabbed my tip and slowly, a fraction of an inch at a time, pulled it up, deeper into her, and her hips settled lower as she took more and more of my excess length into her, first through her widening cervix, and then deep into her womb itself. The tight opening squeezed hard against me as it took in my tip. I felt a pop as the ridge of my glans slid through the muscular ring and into her womb proper.

"Ow," she said with a frown. "This always takes a minute..."

How to explain that sensation? As wonderful as sex is—and, speaking from first-hand experience, sex with a mare is as good as or better than sex with a woman—this was a whole new level. Her wetness, her tightness, surrounded my shaft, and a sensation of even greater tightness, ever more desperate need, as her womb muscles worked to pull my extra inches up into her deepest and most intimate part. The slickness was unreal as her magic brought more and more of her juices into play.

She settled down, fully seated across my hips now, my entire length inside her. The buttplug's end settled in between my balls and vibrated them, the sensation just like— 

"Ohhh," Dash said, and her entire body shuddered. "Now. This is so good. I've never been so full. Th... thank you."

I squeezed her hooves. Wetness simply gushed out of her, soaking my thighs and belly as her body lubricated us. Her pussy muscles clenched my shaft, massaging, as her womb muscles throbbed around my tip, so hot I feared for burns that might require a trip to the hospital. That sensation, the magic pulling me deep into the very depths of her... it's so unlike anything else in the universe. I could see her abs clenching, the ridges of muscle visible through her fur as she clamped down on me again and again, her magic and her instincts and every fiber of her desperate to milk my seed deep into her womb. Her hips, muscled more thickly than any human's, clenched around my hips, pressing me into the bed. Her ass spasmed, too, as the orgasm built, the buttplug pressing and releasing again my balls.

"This is amazing, Love," I said.

She gasped, a choking sound. Her eyes screwed shut even tighter. Her forelegs went stiff as I held her hooves in my hands. Her wings, previously as erect as my cock, went limp as her entire body focused, all of her muscle and willpower and thought centered on her womb as it milked and massaged and tugged on my cock, pulling and vibrating and so wet. I wondered if she might actually sprain my cock with her desperation to pull me in even deeper. Muscles I can't describe rubbed all around my tip, massaging it wetly and slickly in every possible direction and I felt the magic she had stored in me over the last who-knew-how-long coming to fruition as my balls flamed, as deep in my belly my orgasm rose. 

Then, we were both shouting, shouting nothing like words, as her pussy clamped and her thighs squeezed me and her womb clenched down so hard on my cock that it actually left a hickey we found later in the shower, and I came, huge spurt after huge spurt shooting into her, I could feel myself unloading so much more than I ever had before, my load probably five or ten times its usual size thanks to her magic, my balls flaming in a wonderful, throbbing release that was half pain and half heaven as I unloaded not just my seed but also my love into her, wad after wad. I filled her womb so full that my spurts became difficult, my body pumping hard to force my seed out into her as her tight womb stretched against it. She shouted and her eyes went wide as I filled her womb and her own orgasm clamped down across her belly and her hips and her ass and her ears went fully erect, her jaw dropping open.

We stared at each other for a few seconds, my length spasming inside her as the erratic rippling of her belly muscles faded. 

"Celestia!" she said, lifting her hips. My cock popped from her womb, then from her pussy, and a massive hot load of my seed spilled from her, coating my abs and my balls and my hips.

She flopped down, on top of me, her pubic mound landing in the puddle of cum, and my cock pressed against the base of her tail as I softened.

"Wow," she said, wrapping her forelegs around me, her whole body trembling. "Wow."

I nibbled her left ear and she made a happy mmmmmmm sound.

"Hey," Dash said. "Do a mare a favor...?"

I reached down, under her tail, and pressed the button to turn off the buttplug's vibration. I used two fingers to grab its flared base and slowly, slowly pulled. Her tight ass fought to keep it in but my gentle pressure extracted it. She gave a tiny gasp as it slid free, and I dropped it onto the edge of the bed, since we were clearly going to be washing the sheets, anyway.

Now at half-staff, my cock throbbed softly, caught between her buttcheeks, my tip just touching her still-spasming asshole. More of my huge load dribbled from her pussylips, warming us where it touched my skin and her coat. If we fell asleep without taking a shower, we would awake uncomfortably stuck together where my cum glued her coat to my skin, but I didn't care. That was a later problem. The warmth of her weight against my chest was driving me toward sleep.

I rubbed her withers and her wings with my hands, then reached down and grabbed her wonderful, muscular buttcheeks. She kissed my collarbone once, and then fell asleep.

I closed my eyes, and allowed myself to start drifting away.

It was impossible to try to explain monogamy to a pony. She slept with one or another of her friends a few times a week, and some random stallion at least once a month. 

But there was a simple way to tell who a mare was in love with.

If she spent her estrus cycle with you, well, that's how a pony showed you that she loved you.

"I love you too," I whispered into the sleeping mare's left ear, then I fell asleep.
