Cadance cheats on Shining Armor to have sex with Flash Sentry

When Cadance and Shining Armor had started dating, their sex life was whirlwind of ecstasy and Cadance couldn't stand to not be having sex with him constantly... but then they got married. Cadance didn't know if it was the marriage, the pressure of ruling a kingdom or if there was even any reason at all, though the fact of the matter was the same, Shining Armor was no longer sexually satisfying like before. In these circumstances, marriage counselling and communication with your partner is probably the best way to go about it, so being the princess of love, Cadance says "fuck that" and cheats on him instead!

Security Performance

Later that evening as the two of them were getting ready for bed, Shining Armor said "Thanks for earlier sweetie, I'm sorry if I seem kind of needy when it comes to our sex life"

Cadance shook her head and said "No Shining Armor, I owe you an apology. I know we have a lot of royal duties but I guess I should be making more of an effort to put some time aside where we can relax, be casual and maybe have a romantic and personal evening for a while. That being said, the next time I give you a hoof job, can you try not to cum all over my face? You're lucky I had time to clean up before meeting the Saddle Arabians, otherwise I would've had to talk to them with one eye closed on account of having received a very thick and heavy facial, courtesy of the fat set of nuts you've got dangling beneath your cock"

Shining Armor chuckled and said "Duly noted" before they both got into bed, closing their eyes as Celestia set the sun while Luna raised the moon.

An hour passed, Shining Armor was snoring loudly while Cadance very slowly and silently got out of bed before whispering "Hey Shiny... you awake?" Cadance knew that he wasn't awake but always made sure just in case he ever figured out that she was frequently leaving the bed for some mysterious reason, the fact that her voice didn't even interrupt his sleep in the slightest confirmed that he was most definitely as asleep as he could get, that or he was just a superb actor who had already figured out that his wife was consistently sneaking off somewhere in the middle of the night to do Celestia-knows-what.

Cadance left the room, only to be met by the two night guards that were posted outside the bed room for security purposes, with an air of authority she said "I am to visit one of the night guards for a routine inspection on security performance. This is a delicate process and it goes without saying that all security, minus the stallion I select for questioning, will continue to patrol the castle as planned. I am leaving it up to you two to ensure that every guard hears this message so as not to raise alarm that might lead to the disturbance of myself or my husband, am I clear?"

The two guards bowed and said "Yes your majesty", knowing better than to question the princess as to why she saw fit to perform these "routine inspections" so often, especially considering it was only ever one guard that she took aside for talks about "security performance". After avoiding all the places where she knew other guards were stationed, Cadance went to the throne room and, thanks to a handy spell that Twilight had taught her, was able to open the secret staircase that King Sombra had used when hiding the crystal heart. Cadance teleported herself to the bottom of the staircase, ignoring the door that supposedly led to a pony's worst nightmare, conjured up a bed and then simply waited for her favorite guard to arrive so that she could close the secret entrance and get down to business.

Ten minutes went by when suddenly an orange pegasus with a spiky blue mane came zooming down the staircase before coming to a screeching halt. Cadance closed the secret entrance and sternly went "Well, it's about time, you're late Flash Sentry"

Flash got his breath back before saying "Yes, apologies your majesty, my commanding officer demanded I finish my route in the castle before taking my leave, I tried to explain that I was bound by duty to go through a routine inspection with you but he thought I was making excuses to leave early and wouldn't let me so much as take my armor off until I did as he told"

Cadance nodded in understanding and said "Well, I suppose I can't stay mad at you for that, I forgive you. If this happens again I'm going to have a serious chat with your commanding officer, I never want anything getting in the way of these visits"

Neither Cadance nor Flash Sentry could believe that they were able to maintain their odd relationship for so long without being discovered, they weren't romantically involved, it just so happened that Flash was the lucky stallion who Cadance had latched onto when she decided to have an affair. Partway through the marriage, Cadance admitted to herself that her lack of libido wasn't down to age or an increase in royal duties, she just found that sex with her husband had become stale, it just wasn't as satisfying as it used to be and it wasn't doing anything for her to such a degree that she sometimes found herself wondering if she even found Shining Armor even remotely attractive anymore. It was on a day where she had some of the most clunky and uncomfortable sex with her husband ever that she decided to just bite the bullet by summoning a guard to visit her while Shining Armor wasn't around and fuck her pussy in half. Flash turned out to be in just the right place at the right time.

The first time they had sex was a blast, Cadance felt fresh, young and alive again while Flash just did his best to go above and beyond in the line of duty. The following few times were often risky and dangerous because they had yet to establish a reliable pattern or schedule where it would be virtually impossible to get caught in the act, though eventually they figured things out and had fallen into a rhythm of almost constantly meeting up for some casual sex. It was true that part of the rush of the experience was the taboo nature of it, the scandal of a married princess cheating on her husband didn't bare thinking about, though Cadance knew that the simple truth of the matter was that she enjoyed having sex with Flash a lot more than she did having sex with Shining, Shining was a good partner, Flash was a good lay.

Cadance sat on the bed and said "Flash, before we begin our usual activities, I have some rather unfortunate news. I regret to inform you that from now on, my pussy is off limits"

Flash Sentry raised an eyebrow and said "May I ask why your majesty?"

Cadance groaned and went "My stupid husband wants to start a family and the populace wants an heir to the throne, it would give the game away if Shining Armor pushes himself inside of me only to find that I'm already loose and full of cum, so feel free to touch it but don't cram your dick in there and blow a load. Once I have the baby I'll have to try and balance being a princess, a mother and a wife, so our meetings might decrease a bit but they'll pick back up so long as you can be patient"

Flash nodded before saying "Understood your majesty"

Cadance smiled and said "Alright, now get over here on the bed you big lug, I need a cock that deserves a good sucking and you are more than worthy of being granted the pleasure of my mouth. I hope your cum tanks are nice and full because I need your hot spunk in me..."

Flash's cock had already begun to emerge from its sheathe thanks to Cadance's dirty talk alone as he confidently clambered onto the bed. Cadance eyed his cock, not even semi-erect yet, with a tut as she said "Oh dear, can't very well give you a good blow job like this now can we? I know you'll be nice and stiff eventually but I want you hard now! My pussy became so slick while I was waiting for you, so you'll forgive me for being impatient... just allow me to speed things up a little, OK?" Cadance brought her lips to Flash's in a kiss as she lit up her horn and used her magic to gently caress his balls and send tingles of pleasure up and down his cock to hurry along his erection. Cadance was always keen to get started during her escapades with Flash but she never left him unsatisfied and made sure that she tended to him properly whilst still keeping that kinky and erotic vibe that made their sex sessions so thrilling, Flash usually opted to remain silent because he knew that these sessions were mostly for her benefit and he usually received immense pleasure from her actions anyway.

Cadance derived an odd feeling of pride as she felt the need to extend the reach of her magic to make sure she was stimulating Flash's lengthening member, she considered it odd because it wasn't exactly difficult to make a stallion horny, most of them would practically pop a boner if they so much as heard the word "mare", she shrugged it off and just assumed she was a shameless slut, a fitting title considering she'd rather have sex with a random guard than her own husband. Upon feeling that Flash was about as stiff as he could get, Cadance broke the kiss and said "Much better, now get on your side and let me kiss you somewhere that you'll find much more pleasant", Flash complied without question, not that he could deny a direct command from the princess even if he wanted to and he certainly didn't want to deny this request, what heterosexual stallion would say "No" to the offer of a blow job from the princess of love?

Cadance licked her lips as she brought herself level with his stallionhood before opening her mouth and practically swallowing his entire package, one second his tip was between her lips and the next it had been engulfed and was nestled in the warm and wet confines of her throat, the muscles of her esophagus flexing and tensing almost as if to massage his meat. Flash groaned at having the entirety of his cock so suddenly bathed in Cadance's mouth, Cadance herself began moving her head back and forth and moaned in genuine pleasure, the act of sucking off a stallion was something she found quite comfortable on an almost therapeutic level and the raw primal taste of Flash Sentry was a flavor that Cadance found more than palatable, it was borderline addictive.

Flash resisted the urge to thrust no matter how desperately his hips were aching to do so, his body was crying out to give in to his urges but despite Cadance being so eager to blow him, he didn't imagine she would appreciate it if he just started to roughly fuck her face and would most likely tell him that, as a guard, he should have more restraint than that. It was just as the faintest beginnings of a building orgasm had started in his loins that Cadance removed herself with a big *mwah*, strings of Spittle bridging the gap between her lips and Flash's twitching and pulsating rod. After getting her breath back, Cadance went "OK..." as she turned around and presented herself to Flash before simply ordering him "Mount me"

After Cadance conjured up some lubricant to squirt in and around her ponut, Flash stood up, reared back and hooked his forelegs onto Cadance's hips before asking "Your majesty... permission to enter your pussy for lubrication purposes?"

Cadance thought for a moment before going "Well, considering I just lubricated myself and I gave you a halfway decent blow job, I should think you are sufficiently prepared, plus I have already told you not to enter my pussy... ah fuck it, bury it my cunt, so long as you don't fire your creamy jizz into my baby factory I'll allow you twelve thrusts before I insist you aim your big and throbbing dick a little higher so that you can enjoy a tighter hole. Now, I don't intend for my butt to be empty for much longer than it needs to be, so be quick about it!" Flash angled himself so that he was perfectly poised at Cadance's entrance, then without even a hint of hesitation, slammed himself deep inside down to the hilt into her fleshy foal-carrying fuck hole, to which Cadance responded with a surprised yelp that came out louder than she meant it and crying out "Oh fuck! Holy fucking shit! Damn it! I fucking hate my husband and thanks to him I won't get to feel this huge thing in my pussy again until he gets me pregnant! What a selfish bastard!"

Cadance wasn't unaware of the hypocrisy of her statement, it was true that Shining could be a little selfish, especially since he didn't even repay the favor after Cadance gave him a hoof job, though Cadance recognized it was definitely more selfish to cheat on her husband with a superior stallion just because she wasn't enjoying her sex life and couldn't be bothered to talk to Shining about it, finding it preferable to seek out some willing hunk in the form of Flash Sentry to satiate her lustful cravings that her husband failed to deliver on. Cadance grunted whorishly with every thrust Flash gave, retracting himself until just the tip was inside and sliding himself back in all the way to the base, after his twelfth and final thrust he pulled out and Cadance still felt slightly out of breath from such a simple, short-lived and small bout of fucking. Cadance relished these moments with Flash and she didn't envision herself stopping any time soon, to see herself putting a stop to her continued affair was almost a scary thing for her to imagine, in fact it was probably what she would see if she dared go through the nightmare door.

Their meeting was almost over but Cadance knew that due to her own disinterest in her husband and her husbands obliviousness and lack of sexual prowess, there would be a next time, there was always a next time, which is why Cadance didn't feel any regret as she simply said "Ass... fuck it"

Flash moved around a little until his cock was aimed squarely at her pronounced pony princess pucker, gripping her hips a little tighter and pushing in an effort to gain entry so that he could ram her royal rump. Thanks to the preparation, while it did take a considerable amount of force to gain access to her regal rear, Flash found himself working his cock into her backside quite easily and the both of them moaned the deeper his dick delved into depths of her delightfully tight derriere, her anal walls gripping his tool like a sex-starved vice that was anxiously accepting and holding onto his erection as if it had no intention of letting go, lest Flash should pull out before it was satisfied. Eventually, Flash was fully inside, his hips pressed firmly against Cadance's soft and supple buttocks, Cadance had cheeks that were practically begging to be spanked and abused and if it weren't so difficult to hide the bruises, Cadance would have happily accepted that kind of treatment, she was a naughty mare and she felt like she basically deserved to be punished for enjoying the embrace of another stallion.

Cadance loved how full she felt but that feeling was soon overshadowed by the much more intense feeling of Flash's cock pumping in and out of her booty as he started to fuck her at a moderate pace, the only sounds being his heavy breathing, Cadance's whimpers of pleasure and the constant clapping of flesh. This was the kind of sexual gratification that Cadance longed for but the stallion she claimed to love just didn't live up to her standards and she couldn't understand why, it was perfect when they were in their teens and still dating, yet when they got married and were given a kingdom to rule... it fucked everything up. There was a small part of Cadance that hated that she had been setting up these casual hook-ups with Flash Sentry for so long and hadn't felt any guilt whatsoever, blaming everything on her husband for having lost his touch instead of blaming herself for not considering talking to him, consulting someone else, spicing up their sex life or maybe just having sex more often, no, she had gone straight for the "betray him" solution for sex and she doubted that there was a better conclusion.

Cadance's pussy was soaked but she, unfortunately, couldn't stay down here having sex with Flash forever and she whispered "Harder..." despite whispering, Flash could sense the want, desire and need that coated the syllables of such a simple demand, her voice was practically dripping with lust and Flash wouldn't be a very effective or efficient guard if he didn't follow that order. Cadance started moaning out loud as Flash began to really pound her pillowy posterior, the bed started creaking and squeaking, her pussy winked and her butt jiggled, Cadance found the power to speak and encouraged Flash by saying "Yeah, that's it... right there... give it to me... do me like I'm your bitch! Fuck this naughty princess! I'm a dirty and horny mare who loves taking it in the butt! The most exciting and exhilarating thing in my life right now is when I creep out of my bedroom to come here just so that I can cheat on my husband! I wouldn't give up this affair for anything! I don't care if infidelity is wrong and the one and only reason I haven't sealed off this room is so that you can come here every night and fuck me!"

Without Cadance specifically telling him to, Flash started thrusting away harder and faster, his orgasm building up almost as quickly as Cadance's was. Cadance screamed, going full ahegao face as her pussy convulsed and gushed fluid onto the bed, creaming just as hard as the last time Flash had fucked her. It was only a few seconds later that the squeezing of Cadance's anal walls pushed Flash over the edge, holding himself inside her as his dick flared and his nuts emptied, firing several thick and heavy ropes of his seed inside Cadance, both of them feeling the same kind of incredible satisfaction as every other time.

Prologue

"Really? Again?" Shining Armor was complaining, yet again his beautiful wife and the princess of love, was saying "No" to the suggestion that they go to their bedroom for a little bit of sex.

Cadance smiled apologetically and went "Sorry sweetie, I know it's been a while but timing isn't really on our side, besides, when you married me you knew that just because I was the princess of love, that didn't mean I would spend every waking moment making love to you. We have other responsibilities now that we rule over the crystal empire"

Shining nodded and said "I know that, it's just that when we were teenagers you couldn't keep your hooves off of me and now... well it just seems like you're uninterested..."

Cadance rolled her eyes and said "Don't be stupid Shining, I am still very much interested in you and your body"

Shining perked up a little and went "How about just a quickie then?"

Cadance looked into his puppy dog eyes, then let out a sigh as she went "Alright, let's sneak off while we still can and I'll give you a hoof job"

Shining Armor grinned as they both trotted off to their bedroom as hastily as they could.

Epilogue

Flash went back on duty and Cadance zapped away the bed and lubricant before closing up the secret room and climbing back into bed as if nothing had ever happened. She didn't lie in bed and cry about how awful a pony she was for betraying her husbands trust and violating the sanctity of their marriage, Shining Armor was a nice stallion, kind ruler, fine husband and would probably make for a decent father, it's just that he wasn't as sexually satisfying as he used to be and Cadance had decided to pursue... alternatives.

Cadance often wondered if she was lying to herself about how she felt and whether her complete lack of empathy of the situation was healthy or not, questioning her mentality about the whole thing and considering the possibility that she was emotionally unbalanced somehow. Another thing she often wondered is that maybe she had got here because Shining Armor had a physical problem, do ponies usually just stop being good at sex for no reason? More accurately, did ponies often just get bored with their partners? Cadance had so many questions about her exploits and she never had an answer for any of them no matter how long the questions lingered and tumbled around in her head, although one question did have an answer, many would say it was the wrong answer but it was still an answer.

The question was "Should I stop doing this? Should I stop this blatant act of adultery?"

Cadance had asked that question of herself a thousand times, re-affirming to herself that what she was doing was exceedingly and undoubtedly wrong. If Shining ever found out it would break his heart, the marriage would most likely end, ponies would think less of her, family ties and bonds broken, the kingdom might fall apart, she may have even been stripped of her title and alicorn status.

In spite of all of those possibilities, she always arrived at the same answer of "No"

The End
