I bet you thought I forgot about this. Features: Glory holes (sort of), anonymous intercourse in all openings, water sports. Scene continues in the next chapter: I could write a whole novel about shy in the box, but I need to move the plot along.

They’d both come out of the forest stepping on the tips of their hooves and grinning big goofy grins. Stains and smells would wash away, but joy could not be hidden. Applejack noticed the second she saw them, and glared daggers at Fluttershy. Shy had blushed and ducked her head in response, which didn’t help matters.

“Okay, we did kiss,” Fluttershy had insisted when she pressed the matter, “but otherwise we didn’t touch.” She could hardly say it with a straight face. His cum and piss were warm in her belly, and she felt like she was walking on clouds. Except that she hated actually walking on clouds. So wet. So fuzzy. So dangerously high up. So metaphoric clouds.

“You and I are gonna have words, later,” Applejack had whispered, voice simmering with sororal wrath, glancing meaningfully at her big brother as he trotted back to his workshop with a skip in his step. “In private.”

Fluttershy, intimidated, had made an excuse about her animals and fled.

But now it was nightfall, and the euphoria of this morning’s sex had worn off. She was starting to have feelings, again. Nasty, horrible feelings like anxiety, depression, and boredom. Loneliness, because as much as she hated being around other ponies she still sometimes felt isolated in her cabin. Resentment towards bossy busybody Applejack. Missing Rainbow Dash. Confused about her feelings towards Mac. A bottomless of negative emotions that she needed to fill in with a fresh load of anonymous, no-strings-attached cum and pee and pussy juice as soon as possible.

Some mean, cold-hearted ponies called this way of looking at things ‘sex addiction.

They didn’t understand.

Luckily, Twilight understood. At least, she understood it from the angle of needing to get physical needs out of the way in the most efficient way possible so that she could return her mind to her studies. They had spent many a night discussing it in between rounds of licking each others’ pussies raw and finally settled on the Sex Box Mk. I as the best solution for Fluttershy’s needs. A large cardboard box, big enough to cover Fluttershy end to end but not big enough to turn around in, with round openings at each end. One in the front, two in the back. The box was labeled ‘FREE SEX’ and the holes labeled ‘PONUT’, ‘PUSSY’, and ‘SNOOT’ in large black magic marker block letters near the respective openings. Other block letters informed the prospective patron that ‘PEE IS OKAY’ and that ‘NO FUNNY BUSINESS’ would be tolerated, though what exactly constituted ‘funny business’ was left at the occupant’s discretion. Once Fluttershy placed the box over her body, it could not be removed until she willed it to be removed. Certain biometric enchantments would notify Twilight if she were injured or incapacitated along with the coordinates to teleport her out. Otherwise, the thing was like a bunker. Amnestic enchantments ensured that if anycreature shone a light inside, or if she stuck her snout through the front hole for better oral gratification, her appearance would not be remembered. If any inserted member or orifice did not meet Fluttershy’s personal standards, she could eject the body part with a simple act of will.

But Fluttershy’s standards were very, very low when she was in the box. A creature’s appearance didn’t matter. Size didn’t matter. And she kind of liked stinky pussies and crusty cocks. The loveless, the forlorn, the terminally homely, the socially inept, and the horny-yet-lazy, they all knew that if that box was in the alley behind Berry’s Bar and the line wasn’t too long they could find release.

Angel, of course, would not let her go in alone. She had explained that the box was protection enough. He wouldn’t listen. So she let him sit under her belly with an umbrella, a magazine, and a machete, waiting patiently for her to be done.

He was a good pet.

Tonight she felt especially empty after what happened with Macintosh and even more so what had not happened with him. She was sure he’d have been happy to use her body all day if stupid clam-blocking Applejack hadn’t gotten in the way. Wanting to forget about it, she had set up the box early.

A little too early. Creatures passed by, some glanced at her curiously, but none of them chose to investigate. She pouted, yawned, and eventually curled up next to angel and took a nap.

The sound of someone knocking on her box awakened her. “Hello? Um? Hello? Is anypony in there?”

Fluttershy shook her sleepy head, trying to clear her mind. She almost said she was, but she hated to talk in here. The amnestic spell ought to disguise her voice, but she still felt it broke the anonymity.

The stallion outside sighed. “I should have known. It’s just a prank. Ponies are probably hiding and laughing at me right now. I’ll just go.”

In a panic, Fluttershy poked her nose outside the box and opened it.

“Oh!” said the stallion outside, sounding startled. “I… um… guess you are real?”

Fluttershy opened her mouth and rolled out her tongue. Heart hammering, she waited. She could tell the stallion was nervous. Hesitant. Shy. She knew what that last one was like. She longed to reassure him, but she had to let him come to his decision on his own. The agony of waiting for a hesitant patron was part of the thrill for her, after all.

At last, she was rewarded by the warmth and firmness of a cock on her tongue. It wasn’t a big one, but that was nice. Being choked and gagged was fun, but it took a toll on her little body. Sometimes it was nice to just suck off a normal mouthful.

It was a stinky one, though! Its hard length felt rough at first, but as she licked it she realized the roughness was smegma! Dried cum from the stallion stroking himself off and not cleaning up! What a slob! It didn’t seem a nice thought to imagine it was degrading to suck off a pony like that, but she did feel degraded by the act, and she loved it. A shiver went down her spine as the musky, sour taste of the old cum filled her mouth. The instinct to pull back rose inside of her; the instinct to spit out the greasy load forming in her mouth. But she forced herself to keep sucking. She slid her lips back and forth out along the shaft, slowly cleaning it until most of it was smooth and silky.

Then she paused to drool the yellow-white load in her mouth across her chest and fetlocks. The smell rose into her nostrils, rank and delicious. Her clit twitched, and her pussy dripped in the grass.

Angel sighed and flipped open his umbrella.

“Are you still there?” said the shy stallion.

She poked her nose out, wrapped her lips around the flare, and pulled it inside.

“Oh gosh,” he moaned. He was shaking with excitement, his cock vibrating so much she had to hold it near the base to keep it still. With the whole thing held firmly inside the box, she turned her efforts to finishing her cleaning. There were still bits of smegma crusted behind the flare and around the media ring. She worked at these with her tongue, softening them until they slid off into her mouth.

His trembling thighs thumped against the side of the box. “Fudge, fudge, oh… Oh, that feels… funny… I…”

Fluttershy frowned at some particularly stubborn patches behind the flare. She couldn’t get them off with her tongue; she had to work the edges free and then pull them off with her teeth, prompting a whimper of pain from the shy stallion. Well. Maybe that would teach him to keep it clean.

In the dim light of the box, she marveled at her work. The cock that had come in brown and crusty was now smooth and shiny, mottled pink and white. The tip had lovely scalloped edges previously hidden by crusted cum. She’d done a good deed!

The box shook as the shy stallion, unappreciative of her effort, humped the mouth-hole. Fluttershy giggled and popped her mouth over the flare. She sucked it with all of her might, pulling her cheeks close against his shaft. He gasped and thrust his hips faster. His flare began to spread in her mouth, a sign this would be over too soon. Nonetheless, his excitement was infectious. Her heart raced with anticipation of the load that…

Oh! Yes! It flooded across her tongue, musky and sweet, much better tasting than the dried old smegma she’d cleaned off of him. She drank it down hungrily, and when he was done she sucked the last droplets from his slit.

The limp cock whipped out of the hole, and like that he was gone. She heard his hoofbeats retreating. Was he ashamed? Embarrassed? Over-excited? Freaked out? Maybe he was a virgin. She might well have been his first. The thought made the hair along her spine stand on end.

She pushed the edge of her hoof against her clit, rubbed out a quick orgasm, and settled in to wait for her next patron.

She had almost drifted off to sleep again when she heard them. Three stallions, young, boisterous, laughing and mocking each other. Instinctively she froze; these were the kind of males she would be afraid of outside her box. But inside it… oh, she hoped they did pay her a visit. If they were as confident and as energetic and confident as they sounded, they might be a lot of fun.

“Wait, wait, bro,” said one of them. “What’s this?” She heard them shuffle around the box, reading the words written on it slowly, sounding them out as if the written word were a challenge to them.

“What the fuck?” said one of them.

“It says we can piss in it.”

“Dude, that’s gross.”

“Hey but I gotta take a leak.”

“Bro, you’re not going to… You don’t know what’s in there! You’re gonna get your dick bitten off!”

“You only live once, bro.” A long, slim, semi-erect cock entered through the pussy hole. Fluttershy felt hot fluid splash against her hind hooves. She pushed her ass towards the back of the box so that the hot stream was splashing on her pussy. She let out a soft groan of delight as the warm stream soaked her sex. She inhaled deep and rolled her upper lip, holding the scent of fresh piss in her snout. Pheromones danced around her Jacobson’s organ, making her heart race and her pussy twitch.

“Aw, buck yeah,” said the peeing stallion, his voice heavy with satisfaction. “This slut really let me piss on her!”

“Bro, there’s nobody in there.”

Fluttershy giggled. She mashed her thick, curvy yellow ass back against the box wall, trapping it between her massive cheeks. In a single beat of the stallion’s heart, the member went from floppy to bone-hard and ready.

“Ooooh, fudge there’s somepony in there!” said the stallion with his dick in the box.

“It’s a stallion, bro.”

“Fuck you, if they let me put my dick inside them, they’re a mare to me.”

Fluttershy, approving of the bropony’s open-mindedness, rubbed her plump pussy lips back and forth across the hard shaft. The shaft pulled back and jammed forward, probing for her opening. Fluttershy winked her pussy open, but the thrusting cock kept missing; slamming into her taint and rubbing between her thighs. “Easy, bronco,” she whispered to herself. “Just let me help you with your aim a little…” She reached back between her hind legs and aimed him up and then he was inside of her.

Though Fluttershy kept silent, making only the softest and sweetest of groans, the bropony’s pounding took her instantly to the door of absolute bliss. His cock drove into her pussy like a piston, probing, pulsating, pounding against her womb hatch. His hips banged against the side of the box, shaking the whole thing. If it were possible to move it, he would be pushing it across the grass. His thrusts kept coming, relentless, stretching her tight pussy open, with no sign of him tiring or finishing.

She smacked her ass back against him. Her eyes rolled up into her skull. Her jaw hung open. Her tongue lolled out. Drool trickled into the grass. Her soft body quivered with exquisite, submissive pleasure. So lost was she in the sublime sensation that when another cock darkened the mouth hole she didn’t notice until it poked her between the eyes. Fluttershy grabbed it around the medial ring. “Oh, another big one like your friend,” she whispered before guiding it to her piehole. When the stallion felt the wetness of her mouth he let out a war whoop and jammed his cock forward into her throat. Fluttershy gagged, letting out a deep, ugly gurgle. Her abused throat throbbed with pain as she twisted against the penetration, and while any sane mare would pull away from that, Fluttershy literally leaned into it, mashing her face against the mouth hole, desperate to get more cock in her throat.

She hung between the two stallions, hooves barely brushing the grass, jerking back and forth, impaled between the two friends. Her aroused wings spread out and mashed against the sides of the box, her wide wingspan causing them to mush up against the cardboard. She never wanted the sensation to end, but even the most stalwart of stallions could only last so long in her tight holes. The one in her throat came first, bellowing and pounding on the roof of her box as he shot ropes of cum straight into her tummy. The one in her pussy exploded seconds later, filling her tiny right cunt with a load so thick and copious it hurt.

There was a hollow thump as the two studs hoofbumped above her box. Cum poured out of her pussy and mouth when they pulled out of her.

“You want a turn?” the first stallion said to their third friend.

“I don’t want you guys’ sloppy seconds, bro.”

“So do her up the butt. There’s a hole for it right there.”

“Ugh, gross,” said the third stallion. “Poop comes out of there.”

“Well,” said the second stallion, “If you’re gonna be squeamish about that kind of thing, I guess you’re not gonna get your nut.”

A fourth voice broke in. “Piss or get off the pot, guy. Creatures are waiting.” said a fourth voice, a low, gravely voice that she knew well from his frequent visits to the box. She’d never been able to match the voice to a face—which was probably for the best; it felt weird when she had to interact with a box client, somecreature who’d been intimate with her and possibly rocked her world and would never know it—but she loved it when she heard it outside the box.

The third stallion mumbled something, backing away while the gravely one climbed up on the front of the box. This was always how he started—a hard, musky black cock with no medial ring (was he a donkey or a mule) in through the mouth hole. She knew to just take the flare between her lips.

“Speaking of pissing or getting off the pot… ahhh. There we go.”

Hot, acrid urine flooded her mouth and rolled down her throat in a frothy surge.

Fluttershy guzzled, lips locked around his flare, hungry for the gross, humiliating treat. He always came to her with a full bladder, and she loved it.

“Harmony, that feels good,” said Gravely, breathless. “You’re the best urinal in the Canter River valley.”

Fluttershy, of course, was too busy struggling to keep up with his golden flow. It filled her mouth til her cheeks bulged out, and she had to swallow and swallow and swallow to keep from losing any of that precious, pheromone-rich fluid. By the time he was done her tummy was bulging like she was about to give birth, and her brain was buzzing with chemically enhanced lust. Once his bladder was empty, he pulled his hard, dripping cock away from her lips. His hoofsteps clopped around to the back of the box, where he slid his cock in through the ‘PONUT’ hole. She swung her tail to one side and bit her lower lip. Trembled as his flare rammed against her slicked-up and prepared ponut. He pounded against it, battering his way in. groaned with desire as he felt her silky bowels embrace his flares.

Creatures waiting in line murmur with excitement as they saw how much he was enjoying the mysterious mare inside the box.

Fluttershy pressed her ass against the box until it flattened out against the cardboard like cookie dough on a baking pan. She felt her ass-flesh ripple as he used her, driving deeper and deep into her intestines, making her bottom ache, making her pussy burn. He was familiar with her body; he knew how much punishment she could take, and knew what she liked. Which was taking all the punishment he could dish out.

“Oh, your asshole is extra silky tonight,” he groaned. “Nice and tight, too. How do you keep it so tight? You’re a popular mare. The line’s around the side of the building already.”

Fluttershy blushed and giggled at the flattery.

His banter turned slowly to blissful moans. She felt his thrusts quickening, and reached between her thick thighs to rub at her nub, wanting to time her orgasm with his. She kneaded it hard, being rough with herself. If she felt raw and walked with a waddle later. Well. That would just remind her that she’d had a good night.

“Holy Celestia!” gasped Gravely. His cock thickened, and cum spurted into the depths of her body. She came in the next second, gritting her teeth, grinding her leathery hoof-edge against her clit. Her ass clenched his cock, squeezing the last ropes of cum out of it.

He pulled back, gentle, careful, leaving her ass gaping hungrily. “Good girl,” he said, patting the top of the box like it was a dog’s head. “See you in a few days.”

The second he was gone, more cocks rushed in to replace him. One in each hole, hard and dripping pre.

She licked her lips. It was going to be a good night.
