Everypony knew that Bon Bon was a lesbian. It was one of the worst kept secrets in all of Equestria. Common knowledge, one might say. If there were three things that foals learned in their first week of equine kindergarten, it was the alphabet, who the four princesses of Equestria were, and that the best candy in Ponyville is made by a mare who has probably stuck her tongue inside all of their mothers' coochies.

So, why exactly was she sucking Shining Armor's cock in the middle of her shop like it was a XXL peppermint stick?

Because it was Tuesday. And Tuesday was Cheat Day. "Every homosexual knows about Cheat Day," she had explained on numerous occasions, usually to whatever stallion asked about it while balls deep inside of her. "It's perfectly gay to have sex with the opposite sex on Tuesday."

Lyra scoffed every time she heard that load of horseapples. Sure, he preferred to tell people that she was a lesbian, but she wasn't above admitting that she liked a good dick, every now and then. Shoot, it just made her love pussy even more. Speaking of, she'd definitely have to try and get Shining's meat in at least one of her holes, before him and his wife went back up north. She'd help herself to him, right now, except...

"Wow, she's really getting into it!" Princess Cadence remarked, affectionately running a hoof through Lyra's mane, as the mint unicorn ate her out. The two of them were lounging on a cushion, enjoying each other's bodies, just a few paces away from their lovers. The cream earth pony was practically throatfucking herself on the Prince's throbbing cock, making incredibly vulgar GAWK-GAWK-GAWK noises as Shining's member repeatedly pummled her esophagus. A large puddle of drool mixed with precum was forming beneath the stallion's hefty ballsack and Bon Bon had very noticeable tears running down her face. "Are you sure she's a lesbian?"

"Of course, she is," Lyra said, not even bothering to pretend like she believed Bon Bon's excuse. Her hoof deftly rubbed against the alicorn's folds as she explained. "It's Cheat Day: she's allowed to fuck all of the stallions she wants, and it totally isn't straight."

"I don't- Mmm, more of that, please- think that's how it works."

"You and me, both," Lyra muttered, licking along Cadence's cleft, the two of them continuing to watch the show.

Shining didn't even need to use his hooves to guide Bon Bon through the blowjob, the mare just naturally fucked her face into a sloppy mess. This was a mare who could easily become Ponyville's Cocksucking Champion, if only she would just admit to liking cock (rumour has it that the committe planning next year's tournament was going to hold it on a Tuesday, just to see if she'd compete). With a shuddering gasp, she yanked the dripping dick from her throat. She let out a few wheezing breaths, pumping her hoof along the unicorn's length, refusing to let her partner's satisfaction dip even slightly.

"Play with the balls!" Cadence encouraged, grinding her pelvis into Lyra's face, her own orgasm imminent. "It drives him nuts!" she continued, snorting at her own joke. Bon Bon nodded, eagerly lowering her mouth down to Shining's royal jewels. She delicately rolled one heavy orb in her mouth, humming in delight at the luxurious softness of the scrotum. Shining Armor groaned, using his magic to move one of Bon Bon's hooves to his sack, while placing her head back at the tip of his monstrous member. The confectioner, not needing further guidance, resuming her facefucking while she fondled the prince's testicles.

"Good little cocksucker you got here, Lyra," Shining grunted, as the tip of Bon Bon's tongue grazed against his balls while his cock was crammed down her gullet. "She made her way past my ring, like it was nothing! How's a dyke, like her, get so good at blowing stallions?"

"Your guess is as good as mine, dude," Lyra replied, right as Cadence leaned back, rubbing her gash like a madmare, and squirted directly into the musician's face, completely drenching her upper half in sweet mare-nectar. She slowly continued to rub her hoof against the pink alicorn, gently keeping the embers of the princess' lust burning. "It's best to just roll with it."

"Oh, something's rolling, all right," Shining grunted, pushing the confectioner as far deep onto his royal scepter as he could. Bon Bon slapped his hoof away, her eyes shooting daggers straight into his soul, letting him know that this was her day and that she would be in charge of this. Shining gulped, nervously, as he pulled his hoof away, letting his submissive mistress do her work.

"GAWK-GAWK-GA-GLRK!" Bon Bon choked, slightly, when Shining shot his first rope of cum, catching her off guard, and came out her nose. She pulled back until only the tip remained lodged, firmly, between her lips, allowing the bitter saltiness of his load to wash across her tongue. After two more shots were fed to her, she let the stallion's still throbbing cock flop out of her mouth. "Oooooooooh-oh-oh!" she groaned, as Shining continued to dump his spunk all over her face.

"That's right, baby!" Cadence screamed as her second orgasm gushed directly into Lyra's own cooch, the two of them scissoring while they watched. "Cream that slut's carpet-munching face!"

"Woah!" Lyra gasped, reaching her own peak. She fell back as she spasmed in ecstasy, her own cum splashing onto everypony else in the room. One spurt, two spurts, three more shots of marecum rocketed out of her, with the final shot being aimed directly at Cadence's face, causing the Princess of Love to laugh with joy.

"My, somepony sure came, a lot!" Cadence giggled, splashing around in the pudle that Lyra had made.

"Are you talking to me!?" Lyra gasped. "Because your husband has completely coated my beloved Bon Bon's face!" she exclaimed, gesturing towards the other two ponies in the room. Sure enough, Shining Armor lay on the floor, passed out, while Bon Bon sat upright, her face and mane almost completely blasted with seed, gargling a healthy mouthful of stallion sauce. "Like... holy crap, how is Flurry Heart your only kid if your husband can put firehoses to shame!?"

"Uh, girls?" Bon asked, after finally swallowing the mouthful of cum. "As hot as this talk of firehoses is, would you mind cleaning me up?"

...

After Cadence and Lyra's thorough tongue bath of Bon Bon, and the royal couple's departure back to Twilight's castle, Lyra and Bon Bon decided a snack at Sugarcube Corner sounded lovely. A cherry cupcake and chocolate shake for Lyra, and Mr. Cake's cock up her snatch for Bon Bon.

"Tuesday, already?" Mrs. Cake asked, as she and Lyra hoofed one another, watching as Bon Bon ravenously thrust her hips into Carrot Cake's pelvis.

"Yuh huh," the unicorn replied, pausing to take a sip of her shake.

"Don't you ever get j-jealous?" Cup Cake continued, stuttering as Lyra's hoof brushed against her sweet spot.

"What do you mean?" Lyra asked, doubling her efforts against the MILF's clit.

"W-what I mean is," Mrs. Cake panted. "Is that sometimes when my honeybunches gets with a rather large number of other mares-"

"IS THAT ALL YOU GOT!?" Bon Bon roared at Mr. Cake, his jizz dripping out of Bon Bon's tight cooch and onto his balls. "I better get a second load!" she grumbled as she began to work his thin, but long, schlong back up and down inside her cunt. "STAY HARD, DAMMIT!"

"Calm down, Bonnie!" Lyra called from across the room, like her wife was an overly rambunctious foal. "Sorry, please continue."

"As I was say-say-SAYING!" Mrs. Cake squealed, as her pussy spasmed and sprayed her marecum across the room. "S-sometimes, when Carrot has a few too many mares that aren't me, I kind of get a little hurt..."

"Oh, I see..." Lyra said, bending over to clean up her host's mess, lapping up her sweet fluids in nice, long licks against the wood floor. "Nah, it isn't that. I mean, I probably get as much action as her, throughout the day, it's just that... I WISH SHE'D SHARE THE DICKS!" Lyra, moaned. "I mean, yeah, I can totally suck a dick, get my pussy creamed, or get gangbanged by the Manehattan hoofball team any other day of the week, but if I so much as try give a stallion a hoofy, on Tuesday, she won't let me! Doesn't matter if it's a gangbang and I want to help get one of the guys waiting his turn ready, she yells that it's hers!"

"I'm sure it's not that bad," Mrs. Cake said, gently kissing Lyra's dripping folds.

"Back away from him, bitches!" Bon Bon screamed at Starlight Glimmer and Trixie as the two of them walked into the bakery with Sunburst. "When I'm done with Mr. "I-Need-A-Little-Blue-Pill", here, Four Eyes' dick is taking his place.

"Um, I'm gay..." Sunburst replied, nervously.

"Come on, surely you know about Cheat Day? You can have all the straight sex you want on Tuesday, and it's still gay!"

"That's not really a thing," Sunburst whispered to his mares, as they slowly backed out of the bakery, all three of them wordlessly agreeing that Hayburger sounded like a better idea for lunch.

"Get back here and fu- oh, fuck! Give those brats of yours a bastard half-sibling!" Bonnie shouted, while Mr. Cake shot a second load inside of her.

"Don't worry," Mrs. Cake whispered to Lyra, while shoving her whole hoof inside the unicorn's tight pussy. "That probably won't happen; Pound and Pumpkin are what we call 'miracle foals'."

"Come on, Lyra," Bon Bon said, approaching her wife, Mr. Cake's baby batter oozing out of her slit. "Today seems like a beautiful day to relax at the park."

...

Caramel.

Thunderlane.

Gallus.

Princess Twilight after she used a genderbending spell. Note to self, Lyra thought, while watching the Prince of Friendship get a rimjob and hoofjob at the same time, causing him to shoot a load into his own face. Have Twilight teach me this spell.

Gallus.

Big Mac.

Hondo Flanks.

Gallus and Sandbar.

Noteworthy.

Filthy Rich.

Pokey Pierce.

Time Turner.

Gallus, again (Lyra was beginning to suspect he wasn't having much luck with the other ladies today. Also, he needed a hobby).

All day Bon Bon had relaxed in a nice, sunny spot in the park, and gotten plowed by every stallion that walked past, all while Lyra watched, occasionally fooling around with the stallions' wives or marefriends. It was now nearly midnight, meaning Cheat Day was drawing to a close, and this last dick would by Bon Bon's last for a whole week.

Or, more accurately, dicks. Spike had two penises. This had certainly been a surprise to the mares of Ponyville, but a most welcome one. Both of his dicks were now stuffed inside Bon Bon's tight asshole, because, even when the stallion (or drake, in this case) had two fully functional fucksticks, Bon Bon still had to be a greedy cockslut, and not share.

"Gee, you sure are tight," Spike grunted, his tiny wings flapping, furiously, trying to keep up with his lesbian lover.

"Th-thank you," Bon Bon replied, blushing, trying to keep her voice at a decent volume. "I try to not let just anypony fuck my tailhole."

Horseapples, Lyra thought. She let Filthy Rich back there, earlier, and his dick is small, he doesn't know how to use it, and he doesn't even give her expensive presents, like he does to his bitch wife.

"Almost there..." Bon Bon grunted, looking in the direction of Ponyville's clock tower. "Just a few more seconds..."

BONG! Midnight. Cheat Day was now over.

"Oh, I'm cumming!" Spike shouted, his twin spires erupting inside Bon Bon's candy ass.

"Perfect timing!" Bon Bon said, reaching her own climax, her asshole constricting around the packages stuffed inside. The two remained locked together for a few moments, twitching as they rode out their sexual highs. With a satisfied sigh, Bon Bon collapsed onto the grass.

"You did good, today," Lyra said, kissing her exhausted lover's cheek. "Why don't you take a quick nap, here, then we'll go home."

Bon Bon nodded, her eyes already closing. "No hetero..." she whimpered, as Spike's hot, dragon splooge dribbled out of her gaping asshole.

Next Cheat Day's gonna be different, Lyra thought, turning towards Spike. "Good job, big guy," she said licking a few stray globs of cum from one of his cocks. "Think you got enough left in ya for a quick blowjob, before you go back to the castle?" she asked, not even waiting for a response as she quickly engulfed both dicks into her mouth.

Author's Note

In case you're wondering what Spike was doing in a park that late at night, he was taking a shortcut home after Guy's Night at Sweet Apple Acres. And by Guy's Night, I mean him, Big Mac, and Discord played Ogres and Oubliettes, rescued the princess from the Evil Wizard, then gangbanged her. And by "princess", I mean Sugar Belle.
