Author's Note

In this bonus chapter, Twilight decides to make good on her promise to show Spike that no matter what, she is the one and only woman in his life that can really please him properly!

Bonus Chapter: Screwing Spike

Twilight was mixing ingredients in a bowl when the clicking of Spike's claws on the kitchen floor drew her attention. She turned to see Spike just sat next to her and pawing at her shins, she smiled as she knelt down and said "Aw, you're asking permission aren't you? You sweetheart, don't worry, I know Fluttershy is here. You go have fun OK?" Just before she let Spike go, Twilight whispered in his ear "When she's gone... I'll let you fuck my pussy so that you can feel what it's like to fuck a real bitch instead of that whore... then I'm gonna fucking peg you just to remind you that as much as I'm your bitch, you're my dog, my husband and you belong to me... especially your fat dick..." She released Spike and got back to mixing as he ran back upstairs for some fun with Fluttershy.

Twilight was just putting some food in the oven when Fluttershy came back down the stairs with her clothes wrinkled and generally looking very disheveled. Twilight looked at her roughed up friend and went "So... have fun?"

Fluttershy walked up to Twilight, grabbed her by the shoulders and stared her dead in the face with bloodshot eyes as she said "Twilight... you are the luckiest fucking girl in the world and I honestly don't know how you handle Spike and his monstrous wang... if you are still worried that I will want him again then don't, I assure you that I never ever want him to fuck me again because if he does I will go completely mad and insane, possibly in a literal sense... thank you and goodbye..." then promptly left, leaving Twilight to feel confused, relieved, smug and horny all at the same time.

Twilight turned to Spike with a smirk and went "You must have really done a number on her huh? Fluttershy fucks off to Las Vegas for a couple of weeks every year to get her holes wrecked by dogs and horses, not to mention all the constant sex she has with Applejack. You been holding out on me big boy? You wouldn't hold out on little ol' me would you babe?" Spike replied with a simple woof, Twilight simply chuckled before going "After dinner, we'll have that fun I promised you"

Twilight's cooking had gone from amateur to expert over the course of their marriage and tonight's dinner was especially fancy, she had done herself a fillet of salmon stuffed with creamy spinach in garlic butter and had cooked Spike a meal consisting of lamb, butternut squash, kale, rice and cranberries. Most people in town wondered why she didn't just buy him regular old dog food and the ones who understood why she might want to cook for her husband didn't understand why she didn't just do some plain old meat. Twilight had done her research and dogs had a more varied diet than she initially suspected, so she always tried to mix things up and considering the way that Spike always excitedly scarfed down every meal she made for him, her instincts and extensive studies of the dietary requirements of canines had paid off. Once she had cleaned up their plates she had a nice walk around town with Spike and then upon returning she went "Alright big guy, I've made you wait long enough. Let's go to the bed room shall we? I'm in the mood for some hot loving" and started walking up the stairs with Spike eagerly following close behind, sex with Twilight was always a treat he relished.

As soon as Twilight was in her bed room she began to disrobe, throwing various articles of clothing to the floor until she was wearing nothing but her glasses and her socks, Spike was already panting just at the sight of his wife and bitch naked but he really began to salivate in delight when she laid on her back in the bed, opened up her legs and used two fingers to spread her pussy lips invitingly. Twilight felt the same rush of excitement she always felt whenever she prepared for some sex with Spike and whispered "Come on Spike... let me prove that I'm a better lay than Fluttershy, get in here and fuck me"

Spike's tail wagged as the first stirrings of an erection made themselves known while he jumped onto the bed in between Twilight's legs, though being the kind and considerate husband he was, he didn't shove himself in and start humping straight away. Twilight was special and she deserved some light foreplay before the main event, she was his wife after all. Twilight gasped as she felt the wet and warm sensation of her husband's thick and flexible tongue dragging across her aching pussy, lapping away at her folds both to prepare her for his cock but to also just enjoy the taste of her human cunt. Twilight gripped onto Spike's head and exclaimed "Oh fuck Spike... I know I say this every single time but you really know how to lick a girl out! Fuck... where did you learn to treat a woman so good?! I can feel my pussy twitching... holy shit your tongue is amazing! I'm so lucky to have you! I'm yours to use forever and ever! I'm so happy! You gave me puppies! I don't care that you fucked Fluttershy anymore, I just need you in me! Please please please Spike just stop teasing and FUCK ME!"

After Twilight all but demanded that Spike get down to business, she devolved into a series of whimpers and whines as Spike continued to dutifully slick up her already moist entrance with his tongue, his cock slowly growing harder and harder the more he licked her greedy fuck hole. Only when he was fully hard did Spike stop licking and shifted forwards, awkwardly maneuvering himself to fuck Twilight, missionary was always slightly tricky when they were being intimate no matter how much they practiced but they made it work decently well enough to enjoy the act of joining flesh in any case. Spike's first attempt to enter Twilight sent his cock sliding off to the side, the second try wasn't much better as it sent him simply rubbing his shaft against her mound, it seemed that the third time was the charm as he successfully started to sink his throbbing hard-on into Twilight's cunny, stretching out her quivering walls as he descended deeper and deeper into the depths of her baby chamber until he was hilted fully inside her, ready to pound her pussy like there was no tomorrow.

Twilight held back her moans, biting her lip to silence herself as she locked her legs around Spike's hips and wrapped her arms around him before whispering into his ear "Do me Spike... show me how much you love me... make me your bitch..."

Spike didn't need much more encouragement than that and so he began to diligently pump Twilight's nethers, making Twilight groan as she said "Oohh fuuck... I always forget just how fucking big you are! Please, don't be gentle, wreck me!" Spike growled in dominance and started fucking at a much more feverish pace, eager to show his bitch just how perfectly he could sexually destroy her just the way she liked it. Twilight moaned as she gripped onto Spike's fur, ecstasy rippling through her body as his cock just filled her completely like a key in a lock, his dick seemed perfectly crafted to slot into her love tunnel and deliver the best sexual experience every single time, the only time it ever even came close to being too much was whenever he knotted her and that event just caused the mildest discomfort as his tip pressed against her cervix while he blasted his doggy cream inside her. It made sense for breeding but Twilight was done raising puppies.

Spike ramped up the speed and strength of his thrusts, ramming Twilight's moist caverns as hard as he could, he felt his own orgasm approaching quickly as his knot began to swell and he was determined to make Twilight cum before he did. Twilight would have noticed the feeling of the fleshy bulb mashing against her wet pussy lips had she not been so distracted by Spike railing her, she didn't know where he got his energy from but she didn't care, dopamine flooded her senses, goosebumps rose along her skin and the walls of her baby chamber quivered and massaged Spike's tool relentlessly, at this rate Twilight might end up being too tired to reverse the roles and peg Spike like she had intended. Spike kept hammering away, his knot almost fully swollen and his impending climax was mere seconds away, pulling out all the stops, Spike opened his jaws and clamped his teeth down on Twilight's earlobe. Twilight was a little bit of a pain slut, not to the same extent as Fluttershy but she didn't mind being handled a little roughly and it was the very feeling of teeth tugging on her tender flesh that tipped her over the edge into orgasm, her eyes rolling in their sockets as her pussy wildly clenched around Spike's member, Spike had gotten her to finish and now it was his turn to achieve his release... almost.

The knot, as per usual, presented a problem due to its large size and Twilight's baby maker not allowing it to be pushed in. While Twilight was still silently screaming through her orgasm, Spike was aggressively trying to force his knot into her body and it was on his fifth push that her lips parted enough for it to pop inside, Spike practically howled as he emptied his heavy canine nuts into Twilight's chambers, filling her to the brim with as much doggy spunk as he had to offer her. Twilight recovered from her orgasm just in time to enjoy the warmth of Spike's baby batter being packed into every available space in her cunt whilst being temporarily tied to her loving husband, who wasn't able to pull out just yet. Twilight sighed and basked in the afterglow, drawing comfort from her lover relaxing on top of her and also relief that despite how much jizz he squirted into her womb, she wouldn't get puppy pregnant again since she had gone on the pill. After the knot had deflated a little, Spike tried to remove himself from his wife's tight cunny and was met with some resistance, almost as if her body wasn't ready to be so empty and deprived of cock just yet, though several tugs and yanks later allowed Spike's disco stick to slip out of her folds so he could move away and lay down to relax... for a few minutes.

Twilight sat up, wiping the sweat from her brow and brushing away the hair that was clinging to her face as she said "Whoo... baby that was magnificent! I'm just gonna go freshen up, then I'll be back to have fun with your doggy door!" Twilight scampered off to cool down and regain her energy, she wanted to be able to give as well as she could take.

• ten minutes later -

Spike was still lying on the bed, fully relaxed and luckily for him, his balls were still full enough that he could bust a nut. Twilight returned and went to a nearby drawer and opened it only to pull out her jet black strap-on before grinning and going "Alright Spike, you've had your way with me and now it's my turn! Don't go thinking that I forgot what I promised!" Spike almost seemed to huff as if he wasn't particularly in the mood to be pegged, granted it wasn't his favorite activity but he usually liked it well enough that he'd indulge his wife occasionally, though this time he was so chilled out that, for once, more sex was the last thing on his mind. Twilight could sense his mood and went "Aww come on babe, I said I was gonna do this, you've had fun with my hole and I just wanna have fun with yours! Come on, let me fuck you in the ass"

Spike still wasn't interested in having his back entrance penetrated at the moment, Twilight pouted and in a last ditch attempt she said "Will you let me do it if say... oh I dunno, I maybe give you a real nice blow job first? Suck you off a little?"

The suggestion that his wife would engage in a little oral sex in exchange for some pegging caught Spike's attention as he suddenly found himself stood up in a not-so-relaxed manner, tail wagging and ready to go. Twilight chuckled and put the strap-on to one side as she crawled over to Spike and said "Men, so simple. Alright big guy, lay down and let me work!" Spike lied down on his side with his hind legs apart, very clearly showing off his growing erection just waiting to be sucked and Twilight was all too willing to be the one to blow her darling husband, Fluttershy had her own spouse she could fuck. Twilight licked her lips as she leaned down to plant a big kiss on the tip of Spike's semi before effortlessly taking it into her mouth and letting out gentle and quiet moans while she moved her head back and forth, sucking and swirling her tongue around with gusto to ensure that she earned the right to wear her strap-on and fuck Spike from behind, just as promised!

Spike panted happily at having his hardening boner tended to by his wife, he could always rely on her to give a really nice sloppy blow job and he could also always count on her to not only take his entire knot into her gullet and deep-throat him but to also swallow down every single last drop of spunk that he fired off, holding it in her cheeks until he pulled out so that she could physically show him that she had gulped down the sticky substance, a sexy sight no matter the species. Spike was fully hard and Twilight soldiered on, coating his erection in saliva and making as many lewd slurping sounds as she could to make sure that Spike was as horny as possible, despite the slight disappointment she would subject him to. Minutes into the blowjob, Twilight could feel the cock in her mouth pulsing and saw that Spike's knot was about to grow again, which is when she pulled herself back and immediately ceased the blowjob, leaving Spike incredibly bewildered. Spike looked to Twilight and whimpered as if to ask why she had stopped so suddenly, Twilight stated very matter-of-factly "Hey, the deal was that I would give you some oral so that we could do some anal, I never said I'd finish you off, alright?"

Spike could see that he wouldn't get to cum unless his wife got her way, accepting the inevitable and somewhat desperate for release, he got into position with his front half lying on the bed and his back half up, his tail lifted out of the way to present Twilight with her prize, his puckering ass hole. Twilight smiled and said "Good boy, just relax and enjoy it my dear" as she retrieved the strap-on, slipping it up her legs and fastening the straps around her waist to ensure she could wield it properly and really fuck Spike as well as Spike could fuck her... though she knew she could never truly surpass his sex skill. Twilight delved back into her drawer and pulled out a bottle of lube, immediately unscrewing the cap and drizzling a long line of the slippery substance from the base of her strap-on to the the tip before using a hand to spread it over every inch of her fake phallus, making it shiny and slick enough to be squeezed into even the tightest of asses, it was perfect, almost.

Twilight made her way behind Spike and applied some lube to his back door, gently inserting a finger to loosen him up a little and lubricate the inside of his entrance, preparation was key when it came to the delicate art of giving anal to a dog. Once Twilight was satisfied that they were both ready for some good old fashioned pegging, she shuffled forward and gripped onto Spike's hips, gently pressing the head of her strap-on to Spike's rear and hopefully give him a good fucking. Slowly but surely, Spike's ring stretched out more and more until finally allowing Twilight access to his bottom, Twilight was firm yet delicate as she pushed forward and sank every last inch of her fuck stick facsimile inside Spike, pressing her hips up against his buttocks and saying "There... doesn't that feel nice? You enjoying the feeling of being nice and full?"

Spike didn't talk of course, though the light panting he was doing upon feeling the sensation of something so intensely stimulating his prostate was a feeling he enjoyed immensely and yet he always forgot just how nice it was to be fucked. Twilight just smiled and began pumping away at Spike's posterior, she didn't want to hump away at him frantically unless Spike gave some kind of indication that he wanted her to, for now she was just happy to sensually slide herself in and out of him, enjoying the sound of his pleasured panting and the sight of his still erect cock bobbing and pulsing beneath him. It was perhaps only after a minute that Twilight felt Spike's body become receptive and more welcoming of her invasion, even allowing her to thrust much easier, not quite enough so that she could conquer him but certainly enough that she could pick up the pace. Twilight gripped his fur a little tighter and wrapped one hand around his wagging tail for better momentum as she began to steadily thrust away at Spike, determined to please him even if her hips started to ache a bit.

The difference was instantly noticeable, Spike was panting and drooling all over the bed, his hind leg shaking and his knot swelling as Twilight continued to deliver some impressive anal considering that she was putting muscles to work that she didn't use all that often. Twilight was building up a sweat before she heard Spike whine a little, she knew from previous encounters what that sound meant and looked underneath to confirm her suspicions, he was strongly erect and his knot had swelled up as much as it could but Spike had yet to reach the point where he could ejaculate without being touched. Twilight kept up with the speed and strength of her thrusts and reached a hand underneath Spike, clumsily managing to grab a hold of his shaft and start jerking his canine cum cannon with a sense of urgency as she pleaded with him to cum. "Come on Spike, be a good boy for me and shoot your load, I know those balls of yours are just begging to be emptied and I want you to do it so badly. Release yourself Spike, do it, fire off your hot, thick, virile seed and cum for me! Fucking cum!"

The soft plapping of Twilight's lap colliding with Spike's buttocks and the wet sounds of her hand gliding up and down his dick was suddenly drowned out as he howled and had no choice but to comply with his wife's request, shaking in ecstasy and cumming hard all over the bed sheets, a mess that Twilight would have to deal with at a later time, at least before bed. Twilight slowed down her sensual fucking until coming to a complete stop, doing the same with her ministrations to Spike's now deflating dong as she pulled out and collapsed on her side right next to her thoroughly drained dog husband. With yet another amazing round of sex concluded, they both took the time to rest and drift off into a nice relaxing nap.

The End.
