Big Mac puts his dick in Diamond Tiara's mom.

Big Mac and Sugar Belle have been married for about two years now, and it's not like they have a bad marriage or anything. They never fight, they always work together, and they still genuinely love each other. As nice as it is, though, it's gotten a little repetitive... maybe even boring...

That's when they decide to attend a swinger party, but even though Sugar Belle gets paired up with somepony she'll probably enjoy, Big Mac gets paired up with the last option anypony wanted. The real question now is, will Spoiled Rich ruin Big Mac's night, or will Big Mac ruin hers? Or will they both cum?

[boink]

*Squeeeeeaaakk*

The mare breathed a low sigh as she closed the door behind them, listening to the hoofsteps of the only other pony in the room travel away until they came to a halt just a few moments later. Her eyes remained fixated on the floor, waiting for a few brief seconds before lifting up her face with an expression of determination, staring decisively at the door as if it were her enemy. Then, whipping her head backwards, she finally made eye contact with him, although his eyes dropped down instinctively, gulping quietly while his cheeks made his red fur an even brighter shade of crimson.

“Well, are you ready to do this?”

“Er--uh… E-Eeyup.”

Big Mac rubbed his hoof up and down his foreleg as the magenta mare rolled her eyes in annoyance. “Ugh. Why did I have to get stuck with you of all stallions? Honestly, have you ever even been to a soiree like this before?”

“Erm… N-Nope…”

The stallion’s head shrunk further and further into his shoulders the more she spoke, making his nervous heartbeat accelerate along with the mare’s apparent, growing irritation. The room was colder than usual just so that it could accommodate for any physical activity that they might want to explore, but for some reason, Bic Mac could already feel sweat beginning to slide down the side of his face. Maybe he was shaking so much that his body mistook it for exercise. If that were the case, though, then why was he feeling goosebumps all over?

Another sound escaped the mare’s lips, causing the stallion to reflexively squeeze his eyes closed, but just as he was expecting another reprimand, he heard a soft chuckle ringing into his ears. The moment he opened his eyes, he saw the earth pony mare take a seat on the bed beside him, her head facing the door again, her eyes fixated on the oak texture like she was waiting for somepony to walk in at any moment. He’d expected this to be an awkward night no matter what happened, but the following silence was borderline torture. Should they talk about it first or just jump into it? What was the typical procedure for something like this?

Big Mac slowly lifted his hoof, opening his mouth to speak, but before he could say anything, the mare beside him heaved another long-winded sigh. “You don’t seem like the type to come to one of our monthly get togethers. Plus your wife isn’t exactly somepony you’d get tired of after only a few years of marriage. Let me guess. This whole thing was her idea, wasn’t it?”

“...Eeyup…”

“Heh. Figures. I was the one who brought up the idea of having one of these parties to my husband in the first place. I saw the way he looked at some of the mares who worked for him. Honestly, I couldn’t blame him if he wanted to go after one of them. It’s not like I’m getting any younger, and if he’s going to cheat on me, I’d prefer he did it with my permission rather than doing it behind my back. At least this way it can be in moderation, and it isn’t like I don’t get anything out of it. Ugh… I must sound horrible right now.”

Big Mac quickly held up his hooves and shook his head. “Nope!”

“Oh, be quiet, you! What was your name again? Big Mac?”

“Eeyup.”

“Well, listen, Big Mac. Do you know what your wife is doing right now?”

The red stallion flinched at the thought, but after a brief pause to allow the message to sink in, he lowered his downtrodden face to his hooves, swallowing the lump in his throat. “Eeyup.”

Sugar Belle was having sex with another stallion. Not just any stallion, either. She was paired up with Trenderhoof, a young, handsome unicorn that was far more successful than he’d ever be. As much as Big Mac wanted to block out the image of his wife screaming somepony else’s name while he slowly entered her marehood, it was all he could think about since the two were randomly paired up. He grimaced visibly as a real, tangible pain gripped his heart, but rather than feeling sympathetic, the mare giggled with no remorse.

“Oh, that must be the worst feeling in the world. Just imagine your wife, the most important pony in your whole world, feeling somepony else’s penis slipping between her legs. Her hooves wrapping around his neck. Her gasps getting louder and louder.”

Big Mac shook his head frantically. “Nope! Nope! Nope! Nope!”

“Oh, cut that out, will you? She’s not going through with it.” Big Mac’s eyebrow rose, prompting a haughty smirk from the magenta mare. “She’s just like you. Even if it was her idea of going to a swinger party, she’s far too timid to actually do anything with him. Besides, I know Trenderhoof. He’d probably faint the minute she spread her legs.”

Big Mac cringed from the grotesque imagery, but Spoiled Rich giggled quietly before continuing.

“You know, I was actually paired up with him once. He was trying so hard to pump himself up the whole time; mentally, I mean. Not physically. Although now that I think about it, I never did get the chance to see if he was a grower like I imagined. You see, most stallions like him blow up like a balloon, but it’s not like I ever get to enjoy it for long. Why should they care about me, after all? I’m just some old mare that they got stuck with, like you. They get to enjoy a few minutes with me while silently hoping for somepony better next time, and then they never have to deal with me again. Be honest with me. Were you excited when I pulled your name out of that hat?”

“Err, nop--I mean eeyu--I mean--”

Just as Big Mac began stumbling over his words, however, Spoiled began laughing so loud that it echoed throughout the room, making him silently hope that nopony would be able to hear. If he heard somepony making love in another room, that would be one thing, but he couldn’t even fathom the idea of somepony hearing the mare that he’d been paired with laughing at the top of her lungs. The embarrassment from the misunderstanding that would inevitably follow already left a pit at the base of his stomach.

“Really, there’s no need to force yourself to be polite. Honesty seems to run in your family, after all. Except for that whole Gabby Gums incident, but I don’t blame anypony in your family for that one. Diamond Tiara was the head of the committee, after all.”

“Erm… O-Okay.”

Spoiled Rich rolled her eyes. “You’re hopeless, you know that?”

“...Eeyup.”

Big Mac seemed to frown more and more as their conversation went on, still running circles in his mind about what he should do next. Should he have sex with her? This mare just said that Sugar Belle probably wasn’t going to go through with it, so should he just call it off and remain chaste for his spouse, assuming she was doing the same? If she did end up sleeping with Trenderhoof, though, would she feel relieved that Big Mac decided not to do anything with Spoiled Rich, or would that just make her feel guilty?

Suddenly, the magenta mare groaned, pulling Big Mac out of his thoughts. “You know, even though I was the one who came up with the idea to have these parties, I still regret them almost every time. I thought that stallions would be lining up to experience a pussy that wasn’t their wife’s, even if it meant doing it with somepony they probably loathed on the inside. Still, I always wind up getting paired with stallions who are nervous, faithful, and spineless. Do you have any idea how my husband handled his first night of freedom?”

“Uh… Nope.”

“He didn’t even do any foreplay! He just jumped into her womb like it was second nature! That poor Fleur de Lis told me all about it afterwards. I had to practically beg her to come back the next month.”

Spoiled Rich laughed again, although he was beginning to hear past the laughter, to understand why she was laughing in the first place. When he looked at her face, he saw a smile, but the rest of her expression was blank. Even though the noise that came out of her chest sounded exactly the same as how anypony would sound when they laughed, it felt different. There was something behind it that he hadn’t noticed before. It was… lifeless, distant.

Once the mare stopped laughing, she put her hoof to her face and shook her head. “What am I doing, telling you all this? Should we just hurry up and get this over with?”

Spoiled Rich lifted herself an inch off of the bed where she sat, but Big Mac quickly held up a hoof, leaning backwards to put further separation between them. “Er… uh… Nope.”

The magenta mare blinked a few times before shaking her head with another lifeless chuckle, sitting back down and facing forward again. “Right. Sorry. Just because I want to get back at my spouse doesn’t mean you want to. What’s your wife’s name, again? Sugar Belle?”

“Eeyup.”

Spoiled Rich smirked. “She’s very pretty. You’re lucky to have her.”

Big Mac rubbed the back of his neck, ruffling his mane as he blushed awkwardly. “Heheh. Eeyup.”

“Forgive me if I seem blunt, but would I be right in saying she’s bored with your marriage already?”

The stallion’s small smile suddenly disappeared, followed by a long sigh as he nodded his head. “Eeyup.”

“Well, I can’t blame her. This probably wasn’t the life she imagined when she was a filly. I sincerely doubt that her life’s dream was to marry somepony who lived on a farm, milking and feeding heifers, putting pigs into a sty. Plus, with the amount of work you do, I doubt she even gets to see you very often. At least my husband brings home a hefty paycheck when he comes home at night.”

Big Mac cringed in pain. Even though her words stung like a butcher’s knife to the shoulder, what made it even worse was knowing what her life was like before he invited her into his. When he’d first met her, she lived in a village where literally every day was exactly the same for years, where she would make muffins that weren’t even any good, then go to bed and do it all over the next day. She thought she was happy living there at first, but then she realized there was more to life.

Was that same thing happening in their marriage? Was she putting on a smile that she thought was sincere until she realized that she could live a more fulfilling life? Was Big Mac just the new equal sign on her flank that prevented her from reaching the happiness that she deserved?

“She loves you, you know.” Big Mac quickly turned his head in curiosity. “Well, my husband loves me too, but even couples who love each other more than words can describe get bored sometimes. Every day, I ask myself, ‘What if I were just a little bit younger? What if I didn’t have these lines under my eyes? Would I need to sacrifice my husband as much as I’m doing now?’ Oh, just listen to me. I sound so pathetic right now.”

Spoiled leaned forward, burying her face into her hooves, but almost immediately, she felt the soft feeling of the stallion beside her gently patting her on the back, resting his hoof on her shoulder. Then, when she turned to face him, she saw a tender smile, one that was genuinely joyful, unlike the smile that she found herself wearing from time to time.

“Nope!”

“Ugh… You Apples make me sick sometimes. You know that?”

“Er--I, uh… N-Nope.”

“Come closer.” The abrupt request made Big Mac blink, freezing up as the mare beside him patted the sheets beside her. “Come on. You’re not scared, are you?”

“...Eeyup.”

“Fine. I’ll do it for you.”

Big Mac’s upper body stiffened like a board, shuddering discreetly as the mare beside him closed the gap between them. Suddenly, he could feel her thighs brushing up against his, making him gulp and look straight forward, placing his hooves to his lap just on the off chance that the contact awoke something within him.

“There we go. Don’t bother scooching away, either. I’ll just follow you.” Her statement came as Big Mac was beginning to lift himself up again, but immediately, he plopped back down where he was, his eyes never leaving the part of the wall his eyes seemed to fixate on. “So, now that I have you where I want you, why don’t we talk about you for a little while. Doesn’t that sound like fun?”

“Nope.”

“Well, luckily for you, I don’t care. Tell me, when you first joined our little festivity, were you busy eyeing all the stallions you were afraid of your wife getting matched with, or were you looking around at all the mares that you were hoping to spend the evening with?”

“I, err.. Well…”

“Don’t be embarrassed. When you saw me pick out your name, you felt more disappointed than relieved, didn’t you?”

“M-Mrs. Rich, I--”

“You know what I was thinking?” Finally, Big Mac pulled his eyes away from their fixed location to cautiously look over in Spoiled’s direction, noticing a wide grin along her face. “I was thinking, ‘This will break my husband.’ Heh. How childish am I? Just because I can’t enjoy myself, I want to pull him down into misery with me, but just knowing that one of his closest business partners gets to take advantage of his wife… I want him to hear me screaming your name. I want him to feel pain when he hears me cum. I want him to realize that the two of us had rampant, unprotected sex, and for all he knows, I could be carrying your child.”

“NOOOOPE!”

The smile disappeared off of Spoiled Rich’s face instantantly, causing her to look up at Big Mac with an irritated glare. “Calm down. I’m not insane. I just want him to think that you could impregnate me. I’m taking birth control just like every other mare here.”

“...Nope…”

Spoiled Rich raised an eyebrow, but Big Mac’s face drooped, his head getting heavier until it practically fell between his knees. Once the message sunk in, however, the magenta mare beside him gasped loudly.

“Oh, Celestia. Are you trying to have a baby right now?!”

“...Eeyup…”

Spoiled’s mouth moved frantically, making several shapes in the form of letters, but the sound never left her chest, leaving her with nothing but a cringe until she finally breathed out in defeated. “...I’m sorry.”

“...Eeyup…”

“If you want, I know where their room is. I can go in there and stop them if--”

“Nope.”

Spoiled Rich was halfway off of the bed by the time she asked her question, but before she could finish, Big Mac swiftly lifted his hoof and blocked her path, his eyes never leaving his knees. He could see the mare giving him a concerned expression out of the corner of his eyes, but after a few moments of silence, she slowly returned to where she was, nestled up against the earth pony stallion.

“I understand. This was her choice, after all.”

“...Eeyup.”

The two of them waited in silence a little longer, trying to keep their breathing from getting too loud despite the lack of oxygen making them breathe even harder. “Well,” Spoiled Rich began, finally breaking the awkward silence, “I think you shouldn’t worry about it, then.”

“Hmm?”

Once Big Mac lifted his head, he was face to face with Spoiled’s stern glare, piercing into him with her eyes like she could kill him with her gaze alone. “I said you shouldn’t worry about it! You’re here, after all. It’s not like you’ll gain anything from going home with blue balls, and I sincerely doubt your wife is going to be up to sleeping with you after how tonight has turned out.”

“I… Nope! I just can’t do that to Sugar Belle! Even if she did drag me here, the two of us are still married, and I ain’t about to betray that marriage just on account of some silly idea o’ hers!”

“Ugh. You talk too much.”

Suddenly, Big Mac’s entire body froze. His eyes went wide. His hairs stood up. His hooves wanted to shake, but they were fastened so tightly to his leg that all he could do was try to comprehend what was going on. Even still, though, his mind was frozen like an ice cube, halting the sea of information that he needed so desperately to figure out what was going on.

In the next moment, he could breathe again, but that quickly changed once Spoiled Rich’s lips closed on top of his again. It was reminiscent of the way that Sugar Belle used to kiss him when they first got married, when they spent those three blissful nights in Appleoosa on their honeymoon, when Big Mac looked into her lust-driven eyes and entered inside her for the first time, yet it also felt different somehow. Spoiled Rich seemed to add her own personality to her kisses, angling her lips in new ways, sliding her tongue against the back of his teeth, running one hoof up his jaw while the other wrapped around his neck.

Big Mac knew he should push her away, that he should break free and get out of there before they went any further… but his body was frozen. He knew he should be feeling guilt, that what he was doing was wrong, that he was tainting their marriage forever, but none of it registered in his head. He didn’t feel guilt, remorse or betrayal. He just felt frozen, not even able to process his thoughts enough to get her to stop. Was he kissing her back? He didn’t even know anymore. It felt like he was, but maybe it was just out of reflex. Maybe he was doing it to be polite. Maybe he was just scared.

Finally, Spoiled Rich slowly pulled her lips off of Big Mac’s, tenderly biting down on his bottom lip until it snapped back into place while giving him a sultry grin that made his heart turn sideways. “How was that? Surprised?”

“Uh… uh… E-E-E-Eeyup.”

“You know, after all the experience I’ve had, you’d be surprised at how well I can please a stallion.”

Big Mac couldn’t come up with words, and suddenly, he couldn’t even remember how to breathe. While he had been so fixated on her sensuous eyes, he hadn’t even noticed her hoof slipping between his knees, rotating around his shaft and slowly tugging him up and down. This whole thing was terrifying, one that had him so horrified that he couldn’t even breathe, so why, then? Why in Equestria was he getting bigger?!

The stallion gulped, now getting hold of his bearings enough to at least let his lips tremble. “M-M-M-Mrs. Rich, I--”

“Shh, shh, shhhh. You just lean back, and I’ll take care of the rest.”

Everything that was going on seemed to progress to the next level right when he figured out how to handle the last problem, and it didn’t look like things would slow down any time soon. Again, Spoiled’s mouth attached itself to Big Mac’s while her hoof rubbed up and down his lengthening phallus, but all Big Mac could think about was his wife. Would she be angry at him, even though this was her idea? Was she doing this exact same thing with another stallion? Was she taking control, or was she letting him take control of her?

The thoughts were making his stomach churn already, but once he pulled his mind away from his wife, he was stuck facing another more immediate problem again. The mare’s mouth slowly pulled away from Big Mac’s as she slowly slid herself off of the bed, getting onto her knees, her hoof never deviating from the steady rhythm in her wrists. This was going straight in the direction Big Mac wanted to avoid, but how was he supposed to do that? He wanted to tell her not to go through with it, that he was scared, that this was a bad idea, but his brain was so frazzled that even speaking itself was infeasible.

Once the mare’s face was right next to his member, now grown to practically full mass despite his inner turmoil, she looked up at him with a smirk, sending a long lick up the skin of his shaft, making his spine shiver. “Do you have any fetishes, Big Mac?”

“Nope!”

He expected that to turn her off, to get her to cool down for a minute and maybe dampen the mood a little, but she just giggled like that was the answer she was hoping for. “You sound pretty vanilla. No wonder your wife wanted to spice things up a little. I guess that means you wouldn’t be used to something like this, then.”

Big Mac tried to breathe, but the air wouldn’t enter his lungs. Instead, he watched in horror as the mare below pulled her bangs to the side and dropped her face down onto his stallionhood, her tongue and teeth gently caressing his skin on the way down. This was pure terror. When he first vowed to be faithful to Sugar Belle forever, the one thing he feared most was something like this happening, another mare touching him in a way that only his wife should. He felt his heart drop, not because his virtue was being robbed by another mare, but because no matter how he tried not to justify it in his mind, he was starting to enjoy it.

The stallion cocked his head back, feeling the blood stiffen his dick harder as Spoiled Rich’s delicate lips travelled over his skin, gently sucking him on her way back out. Before he knew it, his whole shaft was covered in saliva, which the mare used as lube to slowly stroke him up and down in tandem with her mouth. Big Mac tried to close his eyes, one last ditch effort to be faithful to his wife, but sadly, he couldn’t resist the temptation of peeking just a little and seeing the mare’s lustful eyes staring up at him as her head bobbed on his cock.

“Does that feel good, Big Mac?”

“N-N-N-N--”

“Don’t lie to me.”

The mare tilted an eyebrow, staring straight into his pupils with her hoof continuing to jerk him off. Big Mac sighed in defeat, and with the solemn nod of his head, he quietly muttered, “Eeyup.”

“Then I guess that means we’re good to continue.”

Suddenly, the mare was standing up again, placing her hoof against Big Mac’s chest and slowly pushing him onto his back. Then, once he was flat against the sheets, he lifted his head just enough to see Spoiled Rich climbing up again, only this time, it wasn’t the bed she was trying to get on top of. Was this really happening? Were Big Mac’s vows really about to be meaningless just two years after his wedding?

“Mrs. Rich, don’t y’all think we’re movin’ a little too fast?”

Just as the mare had reached down and grabbed his penis again, she quickly looked up at the stallion, grinning deviantly. “Oh, Big Mac, you have no idea how long I’ve been waiting for this moment.”

If Big Mac had a second virginity, it was gone before he even knew it. She had barely moistened him up by the time she allowed herself on top of him, her eyes quickly closing as she felt his shaft navigating through her inner walls. His thighs tightened, inadvertently lifting his hips up higher and guiding his dick further between her legs. Her vagina seemed to kiss him just like her lips did, soaking his shaft in a thin coat of liquid and pulling against his skin as she lifted herself back up. Before she allowed her lower lips to fully release his member, however, the mare leisurely descended back down onto his lap, her legs shaking in bliss as she felt his stiffening cock penetrating her deeper.

“Mmmmf,” the mare moaned, inhaling quick, staccato breaths before firmly grabbing onto the bed sheets below her. He hated to admit it, but the look on Spoiled Rich’s face--the absolute carnal lust in her expression--made Big Mac’s dick grow even harder, which the mare above him undoubtedly noticed. “Ooooooh, no wonder they call you Big Mac. Unn…”

Suddenly, the stallion could feel her bouncing on top of him, her pussy gripping him up and down as her breathing began to drown out the creaking of the bed below them. He bit his lip to keep himself from enjoying it as much as he could, but once he finally looked down at her nethers, his eyes went wide. What was he doing? Was he humping her?! Was she moaning because he was doing this to her?! Big Mac quickly brought his hooves to her thighs and grabbed her with all his might, trying to slow himself down, yet all he managed to do was pull himself in deeper, practically hitting her cervix with every thrust.

Spoiled swung her mane to the side, throwing her hair over her shoulders while her head hung below. Every time she got a good look at his dick penetrating her folds, her eyes squeezed closed, but she could never go more than a few seconds before the temptation made her look again. Finally, unable to take the stimulation, she craned her neck upward to look into Big Mac’s face, but with the feeling of the stallion’s dick pounding her pussy below, her eyes quickly found themselves rolling upwards, her tongue falling out in ecstasy.

“Ooohhhh! Mmm! Mmm! Big Mac, sweetie, go a little deeper. Yes. Yes. Just like that. Ah!”

Why was he following her instructions? Was he really that immersed in Spoiled Rich’s anatomy? Before they started, she’d bragged about how good she would make him feel, and this whole time, Big Mac had been trying to convince himself that she was wrong. Now that he was inside her, though, it was all he could think about. She was so tight, massaging his skin, pulling his most sensitive nerve endings. She was so wet, lubricating him even more than her mouth had been able to do, and the more time she spent on top of him, the more her arousal seemed to pour over his dick.

“Mmmmm. How does it feel, Big Mac? Feel like you’re gonna cum soon?”

Big Mac gulped. “Nope!” he fibbed, which only made Spoiled Rich smile wider. Soon enough, he’d learn not to lie to a woman like her.

“Oh, really? I can fix that.”

In the next moment, Spoiled pulled Big Mac’s phallus all the way out of her opening, making his body tingle as his head slipped away from her labia, plopping back onto his stomach. Then, with the stallion’s eyebrow raising slowly, Spoiled Rich crawled further towards the bed’s headboard, laying down with her back facing Big Mac. Once she turned her head backwards, however, the red stallion gulped again, feeling the blood racing to his pelvis even faster. Right when he thought he’d be able to take a break, Spoiled Rich pulled on her right buttcheek, lifting it high enough for him to get an enticing view of her vagina and tight, purple butthole.

“Take me, Big Mac. I’m all yours.”

If the view of her pussy wasn’t enough to lure him in, the way her tail teasingly swished back and forth certainly did the trick. Any of the reservations he’d had before had either disappeared or were being completely drowned out by the almost insatiable urges that were now beginning to overwhelm him. This was OK. He’d been given permission to do this. If Sugar Belle didn’t want this to happen, then she shouldn’t have brought up going to a swinger party in the first place.

With the smirk on Spoiled Rich’s face growing wider, Big Mac slowly moved forward on his knees, one hoof gripping his stallionhood with the other grabbing the mare’s waist. He took another deep breath, looking down at her opening as it dripped in thirst, begging him to put his dick inside her again. Luckily for her, she wouldn’t have to wait long.

“Ah! Ooooohhh. Mmmhmhmmm.”

His member slipped in like it was second nature, like her pussy was a glove he’d worn a hundred times. The mare arched her back, her shoulders pinching together in bliss as he ravaged her down below. Without thinking, maybe reaching for anything he could use to support himself, Big Mac lightly pulled on Spoiled Rich’s mane, making her moan louder, her insides squeezing him harder.

“There! Right there! Mm! MM! Yes! Ah! Ah!”

He couldn’t believe how much control this mare had over his mind and body. Any time the mare moved her hips, Big Mac would follow. If she wanted him to penetrate her from a specific angle, she didn’t even need to say anything; she’d just reposition herself and Big Mac would somehow wind up exactly where she wanted him. She must not have been exaggerating when she said she had experience with this kind of thing, at least she had done this way more than Big Mac ever had. If she continued this for much longer, though, he was going to…

Before he could dwell on his thoughts much longer, the mare once again readjusted her position, sitting up straight and falling on top of the stallion’s lap, pushing his throbbing cock to the furthest depths of her insides. Big Mac’s legs draped over the bed as Spoiled Rich bounced on his pelvis, looking back at him with a smirk as his head knocked back in the overwhelming sensation between his thighs. He was going to lose it soon, and he knew it.

“How does that feel, Big Mac? You getting close, dear?”

“N-Nop--” The magenta mare raised an eyebrow, calling his bluff before he could even get one word out. Big Mac, in return, lowered his face with a melancholy “Eeyup.”

“Good,” the mare replied, “because I want you to make sure you get it all inside me”

Big Mac grimaced, but he never once slowed down his pace. He must have been thrusting his hips so fast that he’d need help walking when they were done, his dick now so big that he couldn’t even get it all the way inside Spoiled’s pussy anymore. Once he opened his eyes, though, he saw Spoiled Rich fluttering her eyelashes seductively, bouncing on his lap as if she were trying to force him deeper than she could physically handle. Again, the stallion squeezed his eyes closed, but once his sense of sight disappeared, his other senses took control.

“Ahn! Ahn! Big Mac! Oh, baby, keep going! Harder! Yes! Ohhh, I’m so wet right now. Mm! Mm!”

Even when he tried to block out the sound of her voice--just to keep himself from finishing prematurely if nothing else--the sudden scent of her liquid lust wafted into his nose, making his whole body shudder again. It was like no matter what he did, he was subjected to the wiles of a siren, one that wouldn’t let him out of her clutches until he exploded between her legs. One final time, he argued with himself as to whether or not he really wanted to go through with it, but by now, the voices telling him to stop had gone totally silent, leaving only the voices screaming at him to cum harder than he’d ever cum in his life.

With his mind made up, Big Mac grabbed the mare by the waist, pulling her body in closer with every thrust, making the mare scream louder than ever. There was no doubt that she was trying to make her husband jealous by screaming as loud as she was, but honestly, she probably would have been just as turned on even if she wasn’t married, just from how hard Big Mac was pounding her vagina. Plus, if he was lucky, Sugar Belle would hear her too, and maybe, just maybe, she’d regret giving him permission to have sex with another mare.

Suddenly, Spoiled Rich’s moans were ascending in pitch after every breath, now screaming at an octave he’d never heard come out of a grown mare’s mouth. Was she about to cum too? Just the idea of bringing another mare to orgasm caused his member to stretch so hard that it caused him real, physical pain. It was time to finish, for the both of them.

Big Mac fell back onto the bed, raising his hips as the mare bounced higher into the air, still screaming his name at the top of her lungs. He bit down onto his bottom lip, gripping both of Spoiled Rich’s forehooves with his own as he humped her as fast and deep as his body would allow. Her insides dripped down more and more of her natural nectar, coating him with so much arousal that it drizzled down his side onto the bed below. This was it. Just a few more seconds.

“Big Mac, I’m gonna cu… I’m gonna c… Ahhh! Oh, Celestia, I’m cumming! I’m cumming!! AHHH!!!”

Big Mac immediately followed. The moment he felt her insides throbbing against his cock, his dick responded by ejaculating so hard that even the initial burst overflowed out the sides. In just two brief seconds, he was pumping so much semen into her womb that he couldn’t fit all of the seed he was injecting in her vagina, leaving her dripping with two different kinds of reproductive fluids. She’d screamed so loudly that she’d probably lost her voice by now, instead using this time to gasp for air as her lower body flailed in ecstasy. The feeling of cumming inside a mare was something he’d experienced probably hundreds of times by now, but when he did it with this mare, she managed to make it feel different somehow. It made him feel adventurous. Powerful. Sexy, even.

Before he knew it, though, the throbbing in his penis had simmered down into a light pulse until it stopped moving completely, aside from the way it shrunk back into his sheath. Once the stallion’s member slipped out of her orifice and plopped onto his stomach again, a small white strand oozed out of her pussy, which was also still throbbing in the aftermath of her own orgasm. Finally, the mare wobbled herself off of his pelvis and collapsed beside him on the bed, panting dramatically as they both tried to get air back into their lungs.

“How was that? Did you have fun?”

“Eeyup.”

The mare giggled. “So did I. It’s funny, when you think about it. If I’m being honest, I didn’t think you’d go through with it, but… well… Let’s suffice it to say that I’m glad you did.”

“Heheh. Eeyup.”

Big Mac did have fun, but now that the blood was gradually beginning to make its way back to his brain, the guilt that he’d been trying to block out before was now front and center in his mind. Had he really lost control like that? What was he supposed to do now? What if Sugar Belle hadn’t gone through with it on her end? What was he going to say to her now?

“Big Mac?” The stallion turned to face the mare at his side, noticing immediately the look of total concern on her face. “Are you OK?”

“...Nope.”

Spoiled Rich sighed, rubbing her hoof as she silently pondered what to say next. “I know that what I’m about to say next is probably just going to fall on deaf ears, but… Don’t worry about it, OK?”

This time it was Big Mac’s turn to sigh. “How can I not? I knew better than to come to one of these things, but I did it anyway! And I actually went through with it! What was I even thinkin’?”

“Listen. You’ve done nothing wrong. Trust me, you should see some of the ways that I’ve made other ponies feel bad. You’re a saint compared to me, and honestly, even if your wife didn’t realize it before, I’m sure she realizes it now.” Spoiled Rich then brought a hoof up to the stallion’s cheek, making the both of them smile. “Anypony would be lucky to have you.”

*Knock, knock!*

“Big Mac? Are you in there?”

Suddenly, Big Mac jolted up to a sitting position again. “I--Uh--Err--”

“Hang on a second! He’ll be right there!”

The red earth pony gave the mare beside him an incredulous glare, but Spoiled Rich simply rolled her eyes, pushing herself off the bed and moving towards the door. “You’re going to be fine, Big Mac. I promise.” Then, when she turned around, she did so with a smile, one that was so genuine that he couldn’t help but smile back.

Finally, Spoiled Rich opened the door, revealing Sugar Belle, who flinched nervously in response. “Oh! H-hey, Spoiled.”

“I prefer Rich. Anyway, if you wanted to see your husband, you can go ahead and have him. I’m heading back to the lobby.”

The magenta mare then stuck her nose in the air, walking away with an arrogant prance. Sugar Belle quickly stepped out of her way, but once she looked over and saw Big Mac, she couldn’t help but shrink into her shoulders, dropping eye contact and tracing circles on the floor.

“H-hey, honey. You all done?”

“Eeyup.”

“G-good! That’s good!” Suddenly, the room was filled with an awkward silence while the two of them waited for the other to speak. “S-So, uh… I-Is it OK if I come in?”

“Eeyup.”

The mare tried to smile, but still, she looked down at the floor as she approached her husband, taking a seat beside him on the bed. Even if he wanted to hide the fact that he’d slept with another mare, the room smelled like sex, and there was no way he’d be able to hide how out of breath he was. Sugar Belle, though, still smelled like apple pie, making his mind run in circles all over again.

“So, uh…” the stallion began, coughing into his hooves. “Did you and Trenderhoof, uh…”

“Y-Yeah…”

“...Oh…”

Silence.

“So how about you and Spoiled Rich? Did you…?”

“...Eeyup…”

“O-Oh…”

Another silence, this one even longer than the first.

Finally, Sugar Belle looked her husband in the eye and grabbed him by the hoof. “Oh, I’m so sorry, Big Mac! I was stupid! I didn’t realize it before, but you’re the only one I want to be with! I guess I just got so nervous about my new life that I… I just…”

Before Sugar Belle could finish her sentence, however, Big Mac placed a gentle kiss on her mouth, making her eyes go wide at first until they gently closed, getting lost in the feeling of her husband’s lips. Then, once they pulled away again, Big Mac slowly rubbed his hoof against Sugar Belle’s cheek and quietly said, “Don’t worry. It’ll never happen again.”

“I hope not. Can you imagine what our kids would say?”

Big Mac raised an eyebrow. “Our kids?”

“I, uh… I took a pregnancy test before we came here.” Suddenly, the stallion’s eyes went wide, and with a wide smile, his wife softly said, “Big Mac… I’m pregnant.”

“I… I’m gonna be a dad?”

The two of them stared into each other’s eyes for several seconds, but once the message sunk in, the two of them wrapped their hooves around each other, holding the other close like they’d never have to let go. As silly as it was to say before, Big Mac was glad that he came here. Now he knew without a doubt that even if he shared a sexual experience with another mare, it would never come close to the intimacy he felt with the pony that mattered to him most. Never again would either of them question whether or not they were happy in their marriage. Nothing would ever come close to how it felt being together with their special somepony.

Finally, with smiles on their faces, holding each other’s hoof as tight as they could, the two of them started the next chapter in their lives. A chapter called parenthood, where at least they knew that they’d always have each other.

And if they were lucky, maybe his business partner’s wife would be a little less mean whenever they came to visit.
