A year after her shameful romp with Button's teacher, a band concert for her darling little colt is an unlikely place for an old flame to flare up. Will Button's mother stay faithful to her husband, sitting right beside her?

It's been a year since Theorem came along to recommend Button for advancing a grade. Cream Heart, born with the name Milano, had a moment of estrus (and liquor) induced weakness, giving in to a lonely night of fiery passion. Now, sitting with her husband on one side and the homewrecking unicorn bastard/cutie on the other, Milano is caught in the middle. Being serenaded by an elementary school band isn't helping matters. Will she keep true to her beloved, or will her lust get the better of her and send her down the wrong path once again?

Chapter 1

“This is what we paid weekly lessons for?” Silver Lance droned into her ear while the students on stage all played an awful note together.

Milano leaned into him, her hoof crushing into his thigh. “Honey, they’re just- doing the thing where they- they haven’t even started!” she hissed back, giggling as the crowd of parents settled in. She was swimming. The elementary school’s cafetorium had dreadful acoustics, or she thought it did anyway. The mother didn’t know much about music, but the echoes and everything seemed far from ideal. About a hundred folding chairs faced a semicircle of twenty or so. Tuning Slide, or was it Tuning Fork?, waved her hoof and tapped her cute little baton on her little podium thingy and the students all sat up. She whispered a word, and some instruments played some more, still getting the pitch right.

A hoof in Milano’s left side stopped her from floating a little flirty word to her husband, who sat on her right. She swiveled her head that way, dreamy hearts in her pupils, catching the eye of a stallion, his face immediately snapping to terrified surprise.

“Oh!” they both quietly shouted in unison, drawing a few glances. “I didn’t mean to-” they both talked over one another. “It’s been a while!” again, simultaneously.

The pale blue unicorn beside her drove a railroad spike of emotions through Milano’s heart. She was excited to see Theorem again, yet she overflowed with dread. The memories stunned her, locking up her throat while her mind burned rubber, spinning uselessly, stuck in shock. Her heart thudding away was deafening in her ears, worse than little Button’s drums. Already, the hot little mare was shivering in sweat. The tiny quiver that ran up her spine seemed to loosen her locked body, she managed to unclench her jaw then every other muscle, and forced a tiny breath.

He opened his mouth, showing those pretty white teeth. “It’s wonderful to see you again, and is that your husband? Lance, right?” He seemed nervous, though she was staring hard and assumed she was noticing things a less intense look might not reveal.

The pale coated earth pony looked over her milk chocolate mane to the slim unicorn on the other side. She looked quickly behind her, feeling like she should hide Theorem like he was a broken vase and she didn’t want to be spanked- oh fuck, spanke me, please! I’ve been so bad! “Hey,” he said in his deep voice, rattling her thoughts like a low flyby of a wing of pegasi rattled windows. “Are you Button's teacher?” he asked, smiling ear to ear, oh no he didn’t know! Of course he didn’t, no one knew but them! Milano wanted to melt through the cheap folding chair and through the tiled floor. Luckily, her slumping was getting out of the way of her husband and the stallion who fucked her raw while he was deployed. Poor Lance, stuck on an airship far, far away, he had no clue this cute little math nerd had given her a hell of a lesson. Surely he was faithful, no local floozies, no exotic, ah… Milano couldn’t picture him cheating on her without getting steamed up even more, so she pushed the vengeful fantasy aside. It was backfiring.

“Was, last year. Little Button was underchallenged, so with Milano’s blessing, we had him take summer classes and skip a grade. Oh, where are my manners? Theorem,” he said, sticking out his pale blue hoof, almost small enough to fit in Silver’s frog. They shook hooves, and Milano wanted to scream. Between them, for just a flash, she imagined them joining forces and treating her like a cheap-

The band started playing, beginning with a shocking boom of the bass drum. “That’s our Button!” Lance exhaled, pointing a hoof out at the beaming little brown colt. Thankfully, his silly hat was nowhere to be seen- it was on the drum bigger than him. Of course he put it there.

The elementary band played a thoroughly basic melody. Milano was hardly a virtuoso, but even she could tell the different sections weren’t playing together at the same pace, and being “in tune” was more of a suggestion. Still, she sat up tall and watched her son, then more her husband, and finally the stallion who stole a night from him, with rapt attention: she was so deep in heat she needed a hard fuck or a fire extinguisher.

Milano found herself sucking closer to Silver Lance during the awful, awful song. Suddenly, hooves were thundering on the floor, and she joined along, eyes crossing as the shocks sent vibrations up her spine and just felt so fucking good. The mare gulped and took a deep breath, her cheek on Lance’s shoulder. “I know, right? Our little stallion is driving that band,” he whispered as Trumpet Valve or whoever bowed and addressed the crowd.

“Good evening, fillies and gentlecolts, and thank you for coming to Ponyville Elementary’s one-hundredth-and-first Spring Band Recital!” She beamed, a cute, if a little old, yellow mare shouted into the crowd. “That was ‘Starlight’, and let’s have another round of applause for our little musicians who worked SO hard on…”

“She said hard on,” Milano breathed, nuzzling into her husband’s neck.

He rubbed his cheek on her forehead, giving her a little smooch. “That bad this year, huh?”

“Uh huh,” she warbled, voice cracking the tiniest bit. “Please tell me you’re up for a few rounds as soon as-”

“-as soon as he gets to bed. Though we did promise ice cream with his little filly friend, Sweetie Rolls. Is that her name?”

“No, but I can’t remember what it is, I’m just thinking about-”

“-long, hard hours of practice. And our next song is called…”

The mare sat up and brushed her bangs from her face, fanning herself. Milano’s wet lips pursed and blew out, a desperate attempt to cool herself down, vent hot gasses from the air balloon, filly, calm down. “That bad?” a voice on her left tickled her ear. She simply nodded, her big blue eyes dipping to that homewrecking bastard’s lap.

“We can’t,” she mouthed to the stallion.

Theorem simply nodded, eyes glancing her way. He jolted for some reason, and Milano realized her tail, sticking through the chair, had beat him over his flank. Dammit dammit FUCK! NO!

The stupid, cute, handsome, hung unicorn stood as the next song began- oh no it was so bad. Her little darling was playing on beat, but there was only so much he could do. Her love for their little goofball was more than enough reason to keep her planted in her seat, but that didn’t mean they were actually, ya know, good.

“I forgot my sweater in my classroom, I’ll be right back,” Theorem said. Sweater? Milano was sweating. Well, she was afflicted, that wasn’t fair. The teacher didn’t have a foal in the band, or she was pretty sure, so there was no way he was actually enjoying this. Maybe he was sneaking off for a cold splash of water to the face, he MUST smell how absolutely, pathetically, hopelessly in heat his former fling was, sitting so close beside him. Yes, a little break would be best for him.

Milano smiled at the unicorn, failing to catch his eye as he scooted down to the aisle. A parent or two had the same idea: teeny tiny break from the music. She couldn’t blame them. The mare snuggled close to her stallion, drinking his smell, oh shit she couldn’t stop dreaming of cock! She nipped at his chin and shivered, getting a little pet on her shoulder. “Soon baby, maybe get some water?” his deep voice purred right in her ear, like pouring liquid sex right into her skull. “We’ll be out of here before you know it.” Didn’t he see the stallion she knew get up and leave? The stallion she met while he was away? Be jealous, guard me like a jewel, prick! Milano gulped, a deep breath with her muzzle pressed to his neck did more harm than good. Heat, she couldn’t trust her own head, emotions were running in a panic between her flicking little ears.

“Love you,” she whispered, laying a wet smooch on his ear. The mother flicked her damp tail over his muzzle in the dim light. She looked back to see him glaring at her, though his gaze was aimed further south than her eyes.

Milano smiled sheepishly at a stallion holding the double doors from the cafetorium to the hall, ducking through, willing her tail to behave close to her flank. She trotted on as swiftly as was polite in public. Amateurish paintings and banners about friendship and reading sat in half shadow, only some of the lights were on, surely saving power after hours. The thin, well tread carpet padded her polished hooves as rich memories of her own childhood surfaced. The clandestine notes and smooches, the fun classroom hijinx, the scraped knees and hoof races, it was almost enough to make her forget her primal malady.

She even remembered a cute colt named Comet giving her her first nickname. He was a city stallion imported from Manehatten. The dark blue Comet talked funny, and ate funny (and almost always amazingly delicious) food, and one day she traded a chocolate chip cookie in her lunch with a weird oblong cookie of his. He called it a milaaaaano, with a lot of extra space, it was how he talked. Naturally, she teased him, saying he was saying it wrong, but he teased right back, saying her coat looked like a milaaaaano. She had never actually had a milano cookie up to that point, and of course absolutely loved them. “No, I’m Milano, not Milaaaaaaano! You’re wrong,” she had giggled, but the other fillies and colts caught on. After weeks of every pony delibearately saying her name incorrectly, she was fed up, and insisted they call her Cream Heart instead. Cream for her coat, and Heart for her heart shaped cutie mark.

“Silly nickname anyway,” the mare sighed as she trotted along. She braced around a corner, out of sight of the concert, and gulped deep breaths. “Fucking… stupid stallions… pretty, hunky stallions!” The mare squeaked on her way down the hall, trying to recall where the restrooms were. She walked along, tail flicking hard enough to throw her off balance, making her hips sway.

“Are you drunk?”

She nearly broke into a gallop! Milano bit her foreleg to keep from screaming, stumbling to the wall. “I didn’t smell it on your breath, you do a good job of-”

She looked up, mouth coming from her foreleg with a red smear of lipstick and a string of wet drool connecting her face there. She sneered, showing her teeth, and shoved the stallion into his classroom. Her rear hoof slammed the door shut behind them.

Milano fell tongue first into Theorem’s mouth, moaning hard, hugging him as they stumbled and fell onto the floor behind his desk. “Fuck you,” she snarled, kissing her way down his hot body, teeth biting the knot of his sweater sleeves around his neck and threw it on the floor. Her flanks landed with a jiggle, leaking onto the warm, soft wool. Milano’s muzzle fell into the crook of his hindleg meeting his lap and inhaled deep, a junkie getting her fix of stallion smell. Her twitching muzzle scrunched against the steamy base of his thick cock, nuzzling left and right, just feeling the silky soft texture of the veiny skin. His hooves pushed at her head, so she rode the motion to lap at his mostly unfolded sheath- oh fuck the salt, the natural flavor of his skin it was so-

“Stop!” he shouted, somehow quietly. “Milano, we can’t do this!”

“We’ll be quick, he won’t know. This heat is the worst since fucking… ever, just let me!” She smacked his hooves aside and buried her muzzle under his cock, in his hot sack, moaning hard when she wasn’t sucking deep breaths through her nostrils. “Aaah! YES!” she whimpered, slurping his mostly unsheathed cock into her mouth.

“This is your fault, Milano,” he groaned, arching his back. The mare shifted more between his legs, tucking them over her shoulders, gulping to stroke his growing cock as she injected its throbbing self down her throat. A gentle hoof cupped his balls, tucking them to her chin, feeling their damp heat against her swollen neck. Her noisy throat gagged and coughed and gulped and hacked as she stood on her forehooves, spitting onto his raging hard cock. “Holyfuckingshit!” the stallion whimpered.

“Now!” she rasped, spitting on his dick again. She spun about and tucked her hooves under herself, her hot, winking pussy splashing as she laid her ass down hard on his splayed sweater. The wool soaked her eagerness up like a sponge.

The blue unicorn put his cheek on hers, lifting her neck as he mounted her. “Don’t hold b-aaaahhahahah!” Milano’s voice cracked, she bit his hoof when he silenced her. His fucking cock was like water on a red hot burner, sizzling as it quenched her heat. His rigid dick slipped balls deep inside, meeting her hot womb and pushing to stretch her pussy just fucking right. That swollen cum pump slid along her g-spot, pressing hard against it. She flinched as the ring popped over like a wagon zooming over a speed bump too fast. She lifted her ass as he treated her like a mare should be treated, his huge nuts spanking her horny, hot clit, a big button engorged to accept the intense pleasure. Press here for moans!

And then he began to thrust. “Fwoh mowm!” she squeaked, hoping he understood her. The stallion did not. In two strokes, his nuts clapped on her clit like her son was abusing the bass drum. The music was still playing, right? “Hurry, I’m so close!” she hissed; not chewing her foreleg made speaking so much easier.

“Shut the fuck up, slut.”

His whisper hurt like a slap to the face. Milano whimpered out, shivering in ecstasy. “You know you fucking love it, beg, slut.” His hoof hit her flank, and that was that. He laid balls deep inside, not moving, shoving her hips into the floor, filling her completely with that big unicorn dick.

“Yes… sir.. Fuck me. Fuck me fuck me, please!”

“That’s a good slut, you like my cock more than Lance, don’t you?” Oh fuck you! “Say it.”

He might as well have the antidote to a lethal poison in his hoof. “Ooooooh I need it, so much better than my stupid husband, please don’t stop!” Milano scooped his bunched up sweater over her mouth as she shrieked in frustration, shaking, picturing her husband’s beautiful face in her mind. This was so so so so wrong!

His hooves pushed into the thin carpet as he obliged, sucking little unathletic breaths. At last, his hips resumed their brutal crashing down against hers. “Right there! YES!” she huffed, shaking, tongue drooling on the sweater, or carpet, she didn’t care. She could HEAR the wet percussion, their hot bodies meeting. This wasn’t an all night snuggle, or a kinky evening of drunk sexy adventure and experimentation. This was a raw breeding session, the beta stealing from the alpha right under his chin, something primal drove the mare to shove her flanks back at him. Milano’s horny little mind conjured up all sorts of raunchy ideas that belonged less in a romance novel and more in a biology text.

“I need it, don’t hold back, please!” Milano let out a cry as his hoof hit her cutie mark again, making her moan, then cackle breathlessly, her hips rolling to lift her pussy into his lap.

That fucking flare and his fucking ring pounded over her g-spot at this angle. It was just too much. “THEO!” she squeaked, biting his sweater at the collar, and erupted her hot squirting orgasm. Her cunt tightened up in spasming patterns, crushing his cock in liquid velvet. The mare’s ears flipped back, she could hear this, too, her hot squirt splashing all over the wall and the carpet. She was ready to become one with the planet’s molten mantle, now, seeping through the floor wasn’t enough. She was so full of shame, how could she do this?! Why was it so fucking GOOD?!!?

The orgasm crashed not like a mallet on a drum head, but a stick on a cymbal, ringing for what felt like an eternity. In that blissful, guilt-saturated minute, the loving mother and wife felt that big, powerful tool further ruining her purity. Hot seed splashed into her womb, she could feel the wet warmth. “Not inside…” she exhaled uselessly, muzzle in the stallion’s sweater- oh no it smelled good in spite of the mare spit and sweat. Remorse flooded her as much as Theorem’s hot cum. The lump at her throat felt as big as a watermelon. She covered her eyes with her spitty hoof and held back her whimpers.

It was a hell of a fuck.

It’s okay, she told herself. There’s potions for this, there’s a bathroom, she just had to sneak a little hoof help was all- “ah!” Theorem pulled out, leaving her feeling even more sad. Not a shameful sad, a longing sad, like a child missing her toy, like a mare missing her boy, she didn’t want to be empty.

The adulterous mare wiped her eyes and looked up to the teacher guzzling water from a bottle on his desk. “Ah! Fucking hell, baby, you okay? Want some?” he whispered, floating the bottle her way in his glowing teal glow. She struggled to get her hooves under her and drank deep of the tepid water, finding herself absolutely parched. “My sweater,” he sighed somberly, mopping up the mess. “I’m gonna have to slip the janitor a twenty for this mess, oh it’s on the wall.”

“Thank you, I guess, then,” she purred, giggling. “We need to get back, this never happened, Theorem.”

“What happened?” he said, the stallion’s gorgeous beryl colored eyes glowed in the dim light trickling in from the hall. Oh fuck you, you cute bastard. “Hey, where are you going, slut?” he sneered. The mean tone fit him poorly, but the tug on her tail showed she wasn’t as spent as she thought. His magic dissipated as she marched back. He smugly sat in his teacher chair, his huge balls dangling like his milky cock. “Clean it. Or I’ll tell him myself.”

That made her nostrils flare, her eyes see red, her mouth open wide and- “Omfff…mmmmm…mmmaaahhghffmmmm…” Milano closed her eyes as she gulped, tasting her hot pussy on his creamy cock. Her lips sucked like she was enjoying a really thick milkshake, pulling layers of messy dicksauce from that fat cock onto her tongue. His dick was spongy, squishy, way too fun to suck. She found herself moaning between gag-doped breaths, carefully pushing her lips together to feel the give of the floppy, plump organ. She looked up to check she wasn’t hurting him and used her tight lips to slough off more and more salty sperm, oh fuck it was so wrongfully delicious. She looked up, peeling her damp bangs from her face to stare rubber daggers. She wanted him to know just how much she hated him. Try as she might, her fantasies of harming him always ended with making him cum, cum, cum, cum, never enough fucking cream could ever pour from his cock. No amount of pleasure she could give him would ever be enough. The little cheating mare was smitten.

Theorem’s beautiful cock was rock hard and spotlessly clean when his hoof pushed at her forehead. “Good girl. I’d let you go on, but it’s been fifteen minutes already.”

“Shigf!” Milano coughed, gulped, then gulped again, and tongued at a hair stuck in her teeth. The teacher plucked it and used a few tissues to mop her chin. “You should definitely clean up, Milano. Are you okay?” She gulped a few more times. Her mouth was flooded with saliva, and she felt a teensy bit nauseous, but otherwise she was okay.

Milano used a few hooffulls of tissues to mop herself clean, well, until she stopped dripping so much. “You came a fucking gallon!” she hissed as he did the same with his still firm cock. A burp brought his flavor up, making her gag once more, whining out as her clitoris winked hard. “And how is it not soft?!”

“We went, what, six rounds last time? I’m kind of a-”

“Monster cock, bottomless, cum pumping home wrecking fucking… stud. I know,” she grumbled, shivering. Her heat was quenched, but she knew damn well the smoldering embers would catch within an hour or two. “Where’s the restroom?” Ugh, she could still taste it.

It took a while, but Milano finally cleaned herself up. Try as she might, it was impossible to keep her stride steady. Stupid Theorem and his stupid big cock left her pussy a little sore. She kept her hooves together and slipped in quickly, right between her husband and her son’s old teacher.

Lance had a smug, knowing smile on his face when she returned, and Theorem was already in his spot, looking equal parts evil, cute, and perfectly normal. She prayed as she got comfortable in her seat that he didn’t know, though it sure felt like it was obvious. The band was playing another dreadfully basic tune and Milano hoped it was the last one, for many reasons. “You wash your hooves?” the hunky earth pony asked her, his deep voice rattling her spine- no fair!

“Nope,” she said, wiping her wet hooves on his chest, making him giggle and wrap an arm around her shoulders. Ooooh more stallion smell… yes please. “Sorry, I needed a break, you know why,” she whispered up at him. “Don’t worry, plenty more heat for you to put out later, Doc,” she finished by nuzzling under his chin. She stole a look back at Theorem, finding his eyes on her cutie mark. Bastard.

Milano closed her eyes and hugged her darling husband tight, shivering just a touch. Her shut eyes were wet, and as she sat on her twitching tail, she could feel her pussy was wetter.
