The pollen seemed to have more effects than everyone thought at first. Small changes were happening, little physical tweaks. Someponies found their cum taking on strange properties, someponies began lactating or emitting weird pheromones. Unicorn magic became much more sexual even when it wasn't supposed to be. Everything was a mess but everypony was too horny to think about it.

Sweet Apple Acres started the day off totally debaucherous but it only got worse with the realization that Caramel's cum had literally turned to Caramel. The brown earth pony came to the farm just looking to lick Applejack's yummy pussy, but he found himself instead beneath the big brother of the family. Big Macintosh fucked the guest hard while a big bowl sat beneath him. With the help of a vibrator taped to his shaft he had orgasm after orgasm, his balls never seeming to run out of thick, salty-sweet caramel. The girls waited for it to fill up before dunking apples into it, creating lewd candy apples that they gladly sold to passersby.

“Ah didn't know you liked stallions, Mac,” Applejack noted as she and her sister spun apples in the candy seed that filled the bowl. Her muzzle closed again around the cock dangling in her face, belonging to some customer who decided to get in on the lewd scene while he still could. Said stallion also rubbed the flank of the filly beside him, making her blush and yelp. Whenever they filled up a single platter with candy apples, Granny Smith came by to drop off a new place of apples with sticks through the middle and to take the finished platter. Once cooled and hardened they'd be sold off, and an excited crowd gathered around fairly quickly to discover the lewd wonder of semen candy apples for themselves.

The stoic stallion shrugged. He wasn't a very choosy man. Male, female, something in between or neither. Attraction was attraction, and in the lusty haze of whatever the heck was happening, that extended to pretty much everyone. "I do," was his sole response as he continued fucking into Caramel so hard. Caramel's ass was incredibly tight, responding appreciatively to the thick stallion cock slamming into it so heavily, his own cock flopping and swaying about from the force of the thrusts. He didn't even care how many times he'd gotten off or about the fact his cum seemed endless, because it felt so good. He'd been fucked into over-sensitivity, firing off a new wad of thick sugary cum every minute or so.

He was just glad to be useful for something and not messing it up.

"I hope none of my students see me," Cheerilee said, a little embarrassed as she lay on the floor of her classroom, hind legs entangled with Mayor Mare's. They shared a jaw-droppingly long double-ended dildo between them, both of the mature mares' pussies quite stuffed with the toy. Slowly they worked their ways to the middle, eager to feel their soaking wet pussies rub together. "It would be so embarrassing for someone to show up to class, only to find this!"

Mayor Mare nodded in lieu of sharing her thoughts, which were in order; nobody would be showing up to class in the middle of the day during a public sex epidemic, and that she'd seen one of her students--Scootaloo, she believed--eating Rainbow Dash's ass earlier in the morning. She didn't want to distract Cheerilee from the very enjoyable dildo sharing moment with reality, much preferring to moan and squirm her way further down the toy. Judging by the lusty glares of her body Cheerilee kept giving her, the old gray mare was still what she used to be.

Neither mare could keep themselves quiet as they advanced, the rubber shaft reaching deep into both of them, deeper than either had had for a long time. Too long. It was so relieving, to have a private moment to themselves in the quiet classroom, and it only became better as the last quarter inch each vanished. They shifted positions, coming up for a kiss and grinding their aching clits together, moaning loudly into the other's maws. Every squirm felt amazing as they tribbed, enhanced by the sex toy. It was paradise! The two mares found something they both needed on that floor, and as they raced to their orgasms, they wondered if it would be embarrassing or presumptuous to extend the offer once, or even if, the pollen's effects lifted.

Most ponies paired off solely at random. They saw someone attractive and went for them. There was no specific hormonal pull towards somepony in particular, though people who'd had long-unspoken crushes certainly sought out those who caught their fancies.

But then there was Fluttershy.

Whatever gifted the yellow pegasus with the ability to soothe animals had interacted with the midday escalation of the pollen in interesting ways. Whereas her dear friend Pinkie was being stuffed with cock because she was calling quite loudly out for more, ponies seemed to be inclined toward Fluttershy for chemical reasons. Unbeknownst to her, she gave off pheromones that called the pollen's victims to her, and she found herself overwhelmed by line-ups of stallions and mares alike eager to satisfy themselves with her. Once they got off, they mellowed out a little and could seek someone else or just in general go about their business, but first they had to go through the Fluttershy roadblock.

The pegasus hadn't moved an inch in about an hour. Her hind hooves had dug into the ground as the eighth stallion of the day hammered her sopping wet cunt, which dribbled steadily with a mix of marejuice and semen that formed a large puddle on the ground. It was currently Thunderlane inside of her, the black-furred pegasus hammering into her fiercely. The fact she'd been so well fucked previously only made it better for him, loving the feeling of her pussy filled to the brim with fluid that every thrust dislodged. He especially loved the way it ran down his cock and along his balls, sending a sick little thrill. He couldn't wait to go around front and make Fluttershy lick her mess off of him.

In front, she sucked off not only Snips, but Snails at the same time. The two colts smirked as they ground their flanks together, cocks rubbing against each other as she bobbed her head quickly around their immature cocks. Despite the lacking size compared to the girthy stallions she'd been fellating so far, she sucked them off with gusto, tongue slithering in between their shafts. They snickered and moaned, unable to believe they were getting double head from a gorgeous mare. "Trixie never did this for us!" Snails said. "Fluttershy, you're our new favorite!"

In the library, Twilight's attempts to research the cause of the city's chaos had hit a roadblock. Pinkie was trying desperately to gain entrance into her home, and with her would come a flood of horny ponies who wouldn't want to wait in the long lines that the party pony had set up. Twilight feared all hope of figuring things out before sundown would be lost if she was allowed to breach the library, and she knew that soon enough travellers would find their trips to or simply through Ponyville interrupted by the magical effects.

"It could cause a pandemic throughout Equestria!" she explained hurriedly to Spike as her magic worked to barricade the library. Windows boarded shut, doors barricaded with empty shelves and furniture. Anything she could to keep the biggest moving orgy in Ponyville from invading her research centre. She could hear Pinkie going outside, slurping on Nurse Redheart's pussy and complimenting her for her taste. It would be chaos, and she couldn't allow it.

Of course, it was made harder by the fact she and Spike couldn't keep off each other. No sooner had she explained the direness of the situation than Spike had decided to shove his cock into her mouth. She couldn't see directly in front of her due to the facefucking lizard, and any attempts to speak came out as, "Glurk glurk gluuurk," as her inexperienced throat found itself relentlessly hammered by her assistant's draconic shaft. She couldn't get out a word from that point on, her focus drawn toward the feeling of deepthroating the oddly-shaped penis.

Not helping matters was the pounding heat between her legs. She'd been fighting it off for hours, not letting it rule her. Spike helped keep it at bay, but he was now in her mouth and she could feel a puddle forming on the floor as the alicorn's mighty need to reproduce, more extreme than what anyone else had to face, began to cloud her mind. Her attention dimmed, and the dire situation seemed an afterthought as she slipped a forehoof between her hind legs and began to rub her needy plot. The spells that held the furniture tightly against the door ebbed, and Pinkie's loud insistence that Twilight let her bestest friend in the whole wide world and even worlds that we don't know exist yet into her house.

Author's Note

Sorry it's been such a long wait! I've had a lot to deal with over the summer. But here's a new chapter, ending on a cliffhanger because I'm mean, I know. The Big Mac/Caramel and Mayor/Cheerilee scenes were both requested.
