It was a particular summer in Ponyville, or potentially across all of Equestria, depending on how migrating winds and tides interacted with pheremone distribution. Not just that summer when a young filly's fancy turns to love, but when it turns to overbearing, all-consuming, mind-warping lust-overflowing dripping sticky rut-me-over-a-barn-fence-on-a-hot-day heat. The Estrus season, as it's known.

Not that the effect is exclusive to fillies. Mares, colts, stallions—no one in Equestria is technically immune from the behaviour-altering effects of the annual mating season. Commerce practically grinds to a halt. Other types of grinding happen as well.

For the young ones in town, or across the country (the last time we'll make that particular substitution), Estrus is a time of exploration and new, unsuspected heights. Rather like a twenty-four-seven Hearth's Warming that went on as long as you had somepony else to play with. Or some griffon. Dragon. No species was spared in the Estrus season's merciless spread through the minds and sex organs of the world's occupants. It was a miracle more of the rest of the year wasn't spent preparing for the occasion—but then again, maybe most of it was just in secret, the same way you planned presents as long as you could and then finally gave them out, bursting with joy, on one special day planned out in advance.

Estrus season was more 'freeform'. You never knew exactly what was going to happen.

Today, Spike the dragon1(A dragon is a [definition of dragon here]. - Ed) was on his way to his friend's house. Button Mash had the best game room in Ponyville that Spike knew of, unless you counted Rainbow Dash's giant living room, and that was usually so full of dirty clothes and old takeout containers that it didn't feel very spacious anyway. Besides which, Button Mash's mom, Cream Heart, loved to have company over, and would always take time every hour or two to check on the play-room occupants, offering them drinks, snacks, and a healthy look at her MILFy curves from every angle, most notably the back, where, when she bent over just right, you could make out every line of her big, bulging butt and fat, hanging pony-tits between her legs. She liked to bend over a lot when she was down in the play-room, always managing to drop something or forget where she'd put it for a moment. The dedication of a talented host.

Even though it was Estrus season, Spike didn't anticipate he'd be spending all day every day getting his dragon dick wet. He wasn't exactly adverse to the idea, but just in case, there should be something else to do when everyone was cleaned up and no longer sticky. That's why he was bringing over a copy of Smash Stallions Ultimate. Alicorn Cozy Glow had just been added as a downloadable content fighter, and debate was hotly brewing over whether or not she was overpowered. Spike conceded that any character with infinite jumps was at least slightly overpowered, but he hadn't mentioned it to his friends yet, because none of them seemed to notice and his Cozy Glow was taking a lot of matches as a result. A final smash that turned off the console did seem a little over the top, though.

Button Mash's house was painted a happy mix of baby blue with pink accents on the trim—it looked sort of like a scoop of blue bubblegum ice cream. Spike skipped the doorbell and went straight for the knocker, since he wanted to see Cream Heart from upstairs, and her knockers as well. Ringing the bell would alert the boys downstairs, and give him less time for... sight-seeing.

Cream Heart opened the door with a smile on her face which doubled in size when she looked down and saw Spike clutching his game.

"Oh, hello, Spike! You're looking quite handsome today."

"Thanks," Spike said. He let himself in and wiped his claws off on the carpet in entrance room. Even though he wasn't exactly used to taking compliments, Cream Heart would shower you in them nonstop until you started at least nodding along, and he'd found the more he agreed, the more she lathered him in praise, which wasn't something he could find a good reason to object to. Sometimes she got close and wrapped her hooves around his arms under the pretense of 'checking his muscles'. She liked to wag her tail a lot too, wafting it across his face, carrying just a hint of the scent of her marehood, more potent than ever now that the season was underway. Spike was drooling just thinking about it, and he hadn't even gotten downstairs yet.

As usual, Cream Heart couldn't contain her enthusiasm for guests, nor was she able to hide that the Estrus season was having a powerful, substantial effect on her. Spike could smell the heat and wetness of her pony-pussy just after walking in the door, and he wondered how everypony else was downstairs playing when there was a dripping MILF-slit winking and practically waving you inside. Spike felt himself getting hard, and he covered himself up with the game box, awkwardly holding it over his crotch.

It wasn't very effective. While Cream Heart coudln't see behind the box, she had a pretty good idea of why Spike had moved it there so suddenly. She held a hoof to her mouth and let out a long string of giggles, which for some reason had the effect of making Spike's cock even harder, and even causing it to twitch once or twice behind the game box.

"I can see you've been a little swept away by the season as well," Cream Heart said, her voice soft and sweet like honey. "The boys are just downstairs playing games as usual. Would you like a drink or something to eat before you join them?"

I'd like something to eat alright.

"Uh, no, that's okay. Maybe just a glass of water?"

Cream Heart giggled again and nodded, then turned and walked off to the kitchen to get Spike's water. When she turned, she turned extra slowly, and made sure to wave her tail over her backside, drawing oblivious attention to her squishy butt and bulging teats. Her slit winked once or twice right in front of him, as casual as day, though it might have been just that, given how horny everypony must be.

Spike thanked Cream Heart for the water nervously, still holding his game in front of his youthful erection. Cream Heart gave him one more set of giggles and a gentle pat on the head before she left him to head downstairs to the play-room. Spike considered whether or not to wait for his hard-on to calm down before he headed to join the gang, then seemed to think better of it and walked down the stairs anyway, bracing himself with the hand-rail until the light from the play-room down the hallway lit up the part of the basement he was walking into. Go figure that Button Mash wouldn't have thought to leave any other lights on...

Still, his friends would be easy to find now. He could already hear them around the corner too, it sounds like Button Mash was winning, as usual.

"Oh, yes! I'm definitely coming on top this time! You'd better get ready!" That was Button Mash's voice, definitely, and he certainly sounded close to victory.

"Ungh... no fair! You always... unh... go too fast... for me to keep up..." That was Rumble, who always sounded uncharacteristically cute whenever his usual brusk bravado was sandwiched into close corridors, usually when he was at the bottom of the scoreboard. It definitely sounded like he was at the bottom this time.

"Hey, Button, wanna play a game after you're done?" That was Pipsqueak, his tell-tale accent was hard to miss anywhere. It sounded like he was talking between sips of a tall, cool drink... Spike wondered if he should have asked for something tastier than water. Or maybe somepony would share once he got in.

He could just hear Snips and Snails too, the pair was usually around when gaming was going on. But it didn't sound like they were saying much... maybe too into their match to notice anything else going on? There was a lot of grunting and swearing, it sounded like things were getting pretty intense...

"Hey, guys," Spike said as he came around the corner and through the play-room door. "I brought Super Smash Stallions. Anypony wanna play?"

"Coming!" Button Mash yelled. "I'll be there in a minute... Right now I'm cumming!"

He definitely was. Rumble was bent over biting the carpet to keep from moaning too loud, and Button Mash was plowing him from behind like his hips were set on auto-pilot, a piston or jackhammer that repeated its motions until finally—

"Ungh!" Button Mash yanked his cock out of Rumble's tight colt-butt and propped it up on his ass. He stroked himself a few times and started firing a load of hot, sticky cum up Rumble's back and into his wings and feathers. A few shots dribbled down his ass-cheeks, and one particularly long and slippery strand headed straight for the play-room floor.

Pipsqueak flew into the air with a world-class dive, hitting the carpet so fast it looked sure to leave rug-burns and skidding until his mouth was hanging open just underneath the strand of sticky white stuff. When it fell, he caught it on his tongue, and swallowed it up just in time for the next drop. He caught a few more before finally attacking the source with his tongue, lapping up the pool of cum on Rumble's butt and then attending to his wings with a mix of tongue and paper-towel.

"Fuck," Button Mash said, wiping his forehead off with his hoof. "That was awesome. Almost as awesome as Super Smash Stallions," he said, jumping onto the couch and grabbing the first-player controller before Spike had even put the game in. "Let's do teams instead of free-for-all."

"Hey, I just got here," Spike said. "Gimme a little bit to get settled in before you start kicking my butt."

"Or he could do somethin' else to your butt," Pipsqueak chimed in between mouthfuls of cum, using his tongue like a delicate paintbrush to catch the hidden drops nestled in Rumble's wings. Rumble cooed delicately, again out-of-character for his brash exterior, but adorable in any context regardless. He sounded a little bit like a singing pigeon.

"Snips, Snails, are you guys gonna come play with us?" Button Mash yelled with his head turned. He'd already picked his character—never lose with the Smooze, he liked to say—and was rapidly toggling the select token on and off, making the game shout 'SMOOZE' 'SMOOZE' 'SMOOZE' over and over again, kind of blurring into each other like a sampling board. Sm-sm-sm-sm-sm-sm-smooooooze!

Snips and Snails were locked into a sixty-nine and both occupied with attending to each other's cocks, but they still noticed Button Mash calling to them, and both turned their eyes, then pulled their mouths off with dual-sounding slurps.

"Sure!" Snips said, a smile lighting up his face. He might not be the best player, but it was hard to match his enthusiasm, though the salt that came after a while of losing could be rough to deal with as well.

Snails just nodded with a happy grin. He'd been enjoying the start of estrus season more than anyone, it seemed. Maybe it was hard not to with a dick that big.

"I've just gotta make Snails cum... we're racing to see who gets the other one off first!" Snips chuckled and licked the head of Snails' cock, which prompted a groan and bucking of hips upwards. "Shouldn't take too long. Snails always cums real quick."

"Do not—ahhh!" Snails abandoned his protest as Snips slid his mouth down the shaft of Snails' cock again, and his hips moved back and forth automatically, pumping like a piston on a gear, barely able to find the use of his own mouth to fight back. He managed a few half-hearted licks and laps at the head of Snips' dick, but it was nouse—Snips had taken the entire length in his throat and was humming and bouncing his head up and down so the head of Snails' cock bounced against the back of his friend's throat.

They'd been playing for a while already, and Snails did in fact have a reputation for being an early shot. He wanted to hold out, to prove he had just as much stamina as his friends... but then Snips started licking his balls, and he felt them clench at the same time, and a load of cum shot up his shaft and out down Snips' throat like a unkinked garden-hose.

Snips took the first few shots proudly, but when the third one started to dribble out of his mouth, he was forced to pull his head back, and as a result got shot in the face with a fat spurt of sticky cum that clung to his nose and chin and dripped down onto his chest. Snails might have been quick, but he was no slump when it came to the quantity of his cum. Those balls were full and hanging heavy every day.

Even though Snips hadn't cum, he didn't seem to mind. He was all smiles, with cum plastering his face like the cream from a meringue (did we spell that right?).

"Come on," Button Mash said, not wasting any time. He patted the couch cushions to his left and put two controllers up onto the same cushion. "You guys can be one team. Me and Rumble be will be the other team."

"Oi, has that one got room for six players yet?" Pipsqueak asked. He'd finished cleaning Rumble off and apparently washed himself up a bit as well, because he looked squeaky clean and eager to get covered in another sticky load.

"No," Button Mash said quickly. "Sorry. But if you guys wanted to suck us off while we were playing..."

"If it doesn't have six players, why are there eight controller ports?" Spike asked. He counted them up one at a time with his claw, one two three four five six seven eight, even though only four were plugged in right now. Surely Button had another controller around here somewhere.

"Those are for display only," Button Mash said.

"But why would they look identical to the other ones if—"

"Display only!" Button Mash yelled with a glare. "Display. Only."

"Aw, shucks," Pipsqueak said. "Well, I suppose I could work out the ol' jaw again..."

"Come play with me for a bit," Spike said, waving his claw to Pipsqueak and gesturing to a set of chairs in the corner of the game-room. There was always something to sit on or sprawl out over if you looked for it, and Cream Heart probably would have let you use the bed upstairs if you asked her.

"How's your mom been doing anyway, Button Mash?" Rumble asked. He looked away innocently while he waited for an answer.

Button Mash raised an eyebrow and set down his controller.

"My mom? What do you wanna know about my mom?"

"You know. The season and stuff. She's one of the caretakers, for the boys who are in heat and stuff. I just wanted to know, like... how's she doing?"

"I still don't get what you're asking," Button Mash said grumpily. He crossed his forelegs across his chest. "Why do you guys always wanna know about my mom."

"Twilight was supposed to be my caretaker, but she's having some issues," Spike said. "When I got up for breakfast this morning she was all shy and weird... and when I bumped into her while I was putting my cereal away, she blushed and said something in a squeaky voice and ran off to her room. And slammed the door really loud." Spike thought for a moment. "Do you guys know what kind of sound a vibrating toothbrush makes?"

The squad seemed to ponder as well. Nopony had a good answer.

"My mom's doing fine," Button Mash said, the grump still in his voice. "It's... whatever. She hasn't had any issues."

"Is she... 'helping you' with your heat?" Rumble asked, finally giving away his intrigue and turning to stare at Button Mash for an answer.

"What's that supposed to mean?!"

"Oh... you know. Like, is she sucking your dick or anything?"

"Oh... well, sometimes, yeah."

"I thought you guys wanted to play video games!" Snips yelled. He'd gotten a controller and was sitting next to Snails, the two of them bouncing their icons randomly around the screen, letting the internal timer roll the dice wherever it saw fit.

"I do! And we're totally gonna kick your butt," Button Mash said.

"Speaking of butts..." Pipsqueak chimed in again. He and Spike had laid a few blankets out on the floor, enough room for them to get as rowdy and as messy as they wanted.

Spike could tell Pipsqueak was talking about him, from the way he said it, and from the way he squeezed Spike's ass with his hooves, and made Spike feel all warm and tingly and a little delicate which he liked very much.

On the couch, the colts were already getting into their teams game, and Button Mash and Rumble had taken an early lead.

"Losers give head," Button Mash called out quickly before he smashed Snails' character (a gaggle of parasprites all controlled as a single entity) off-stage.

"Hey, no fair!" Snips yelled. "I mean, not that I'm complaining, but..."

Spike and Pipsqueak had begun to frolic with each other, starting with timid kisses and then progressing into full-on makeouts. Spike was still getting used to the idea of expressing his lusftul feelings, the notion that it was not only okay to play and laugh with your friends but also kiss them, touch them, make them moan and pant and feel good and get your scales all sticky with a hot load of creamy cum.

Spike liked that part a lot.

Kissing Pipsqueak was different than kissing anypony else, or maybe it was better to say that everypony Spike kissed felt different. Rumble was rough and passionate, Button Mash was commanding and forceful, Snips and Snails each their own version of innoccent and perpetually confused. Pipsqueak was a little playful, he liked to tease with his tongue, not quite moving it all the way into Spike's mouth, making Spike think they were tongue-kissing, hot and heavy, and then feel extra hot and embarassed when he realized he was going crazy with his long little dragon tongue while Pipsqueak was simply lying back and letting things happen. It made Spike feel like he'd been tricked, but in a good way?

He always got hard before Pipsqueak too. Pipsqueak was sure of that. He liked to brush his hoof over Spike's chest and trace down just above his dick, touching it in little taps that were so light and insubstantial if Spike said they were there, Pipsqueak could simply turn the other cheek and pretend otherwise. The overall feeling was of getting very hot and bothered with a very hard dick but not really being sure what to do with it. It felt like he and Pipsqueak were playing a different version of the same game the colts on the couch were. Maybe someone would have the high score by the end of the day.

"One life left each," Button Mash quipped. He seemed to ingest the images on the screen like fresh sunlight to a flower, and his hooves moved on the controller in a constant blur.

In desperation, Snails reached out and attempted to play with Rumble's dick, to throw him off, but Rumble managed to keep both hooves on his controller even with Snails rubbing his cock, and while Snails was paying less attention to the controller, his character (a large rock with a smiley face) was easy to knock off stage. You just kind of kicked it, and it fell really fast. It was a rock, after all.

"Dang it!" Snips said. He'd been counting on Snails for the clutch factor. Never count a friend out.

Still. It was more of a reward than a punishment. Button Mash was already spreading his legs and lowering his controller, stroking himself half-hard and eyeing Snips and Snails' mouths eagerly.

Rumble seemed excited too, like he'd been hard all day and was just finally getting a chance for some relief. When Snips came up to him, knelt down, and began to lick playfully at the head of his cock, Rumble groaned loudly and leaned back against the couch, tilting his head backwards with his eyes shut. A crystal-clear gob of pre-cum spurted out of the tip of his dick, and Snips licked it up with a grin and a wink, savouring the soft, salty musk flavour and working his way further down Rumble's erect cock.

Pipsqueak had finally started paying proper attention to Spike's hard-on as well, he was stroking it with one hoof while giving Spike all the kisses and attention he could handle upstairs, around his neck and shoulders and collarbone and each one felt like a little burst of electricity that dissipated through his scales. Spike's hips were rocking back and forth of their own accord, knowing only that every time they moved forward, more of his cock would been rubbed against Pipsqueak's hoof, and that was good, and he was already getting really stiff and sticky and making a mess on Pipsqueak's hoof...

"Here," Pipsqueak said. He stopped jerking Spike suddenly, but spun around and waved his butt in Spike's direction, which was enough to wipe the frown off the little dragon's face.

Spike licked his lips and tasted the salt and sweat in the air as he stood and lined himself up with Pipsqueak's wiggling, presented bottom. Pipsqueak giggled as he felt Spike's cockhead against his asshole, and stuck out his tongue with a little flirty smirk.

"Don't forget the lube," he said, and pointed to a small tube lying on a clear-glass table nearby. Spike grabbed the tube, popped the tube open, and squirted a healthy amount onto his shaft, and a little bit between Pipsqueak's cute little butt-cheeks as well. Pipsqueak giggled and shivered as the cool liquid flowed over his coat.

"That should be good," Spike said. He tossed the tube haphzardly in the direction of the table, which it landed under. Eh, close enough.

"Feels good to me," Pipsqueak said with a grin. He reached back with both hooves, one on his butt-cheeks to pull them just a little wider, the other to touch and guide Spike's slippery cock as it slid inside him. He could feel the head there, Spike was beginning to push forward—there, that was it, he was getting nice and full now...

"Oh, buck," Rumble said from the couch. Snips was bobbing up and down on his cock like a professional dick-sucker, which may have been a talent enough for Snips' cutie mark in another dimension. Snips got all the way into it, closing his eyes and humming and moving himself just gently with the motion of Rumble's hips, he seemed always to have just enough room to shove the whole thing inside...

"Cumming," Rumble said, and groaned as his hips pumped forward and shot a load of his cum into Snips' waiting mouth.

Snips took the load with a pleased sounding moan, and did his best to catch every drop as it sprayed the inside of his mouth and down his throat. It wasn't the first load of cum he'd swallowed today, and it certainly wouldn't be the last. He was practically beginning to develop a taste for it. Though, maybe Cream Heart would bring down some Tang later to help keep his palette open...

When Rumble had finished cumming, only a few drops leaked out from between Snips' lips, and he wiped them up with his hoof, wearing a satisfied grin and licking the last of the white, creamy liquid from his lips.

Over on the other side of the couch, Button Mash was apparently the subject of a more languid type of blowjob. Snails was alternating between long, seductive licks up the side of Button's shaft with his lengthy tongue, and stroking the base of Button's cock with both hooves, doing dual-duty with mouth and hooves, making sure there was never a part of Button Mash's cock that wasn't receiving proper attention. Every now and then he'd reach down and squeeze the young colt's balls too, and that got an extra loud groan and a super passionate thrust so hard Snails could almost feel the head at the back of his throat. He wasn't used to the idea of anypony as big as his own cock, so whenever somepony pushed him to his limit, it made him extra horny. His cock was hard again, dangling absurdly between his legs like an erect flagpople. Or an engorged Wii sensor bar.

Pipsqueak and Spike were deep in the throes of rutting. Each of them had their head thrown back, eyes closed, moaning incoherently as their bodies slammed against each other on autopilot. The game-room reeked of sweat, cum, and nacho cheese chips, thanks to the perpetually present bag of them Button Mash liked to drag around.

Upstairs, Cream Heart had begun to prepare the first snack tray of the day. She wanted to make sure all the colts downstairs got a nice and healthy dose of nutrition so they'd have lots of energy. Maybe even enough for her to borrow a little...

Ah, the throes of estrus season. But it all had to start somewhere, didn't it, and the boys had gotten the privilege of some very personal and private instruction before the heat wave had swept through the entirety of Ponyville.

And who better to instruct the colts on their newfound lust and enthusiasm than their dedicated and hard-working teacher, Miss Cheerilee?
