You lay there in your bed thinking back to Roxy, and all the fun you had with her. It was a rather unique experience for you to say the least, you had never been so horny before in your life. Plus the fact that she was technically a wild dog didn’t bother you in slightest, probably being in this magical world without another human in sight for over a year or so gets you kind desperate.

Your hand traces over the collar, and thinking about how Roxy told you it would let her know where you are. You didn’t really understand how, granted you didn’t understand a lot about magic in this world, other then it can do strange things at times. Yet with the limited things you did know in this world, and things that Twilight and anypony else in town had helped explain to you, you wanted to know more about Diamond Dogs.

From what you learned, the pack you witnessed seemed to be all female, which seemed odd. Even though this world differed totally from your world in many ways, you figured some things could be constant. You have seen the ponies act in similar ways to the ponies back home, and even some of the other creatures, and so the Diamond Dogs should act similar to a pack of wolves or some other wild canines.

“But they don’t...” You say to yourself as your body finally relaxes after getting aroused from your thoughts when you first arrived home.

You found yourself wanting to know more about them, everything from the ways they organize packs to their mating habits. For research purposes the former was much more appropriate, while the latter may help you if you ever were captured by Roxy’s goons again. The best, if not only, place to try to find any information is at the Golden Oaks Library.

The next morning, you made your way towards Twilight’s place. Along the way you got lots of looks from ponies, their eyes are focused on your new accessory. Granted you didn’t really mind, you got the same look when you first got yanked to this place. This was the first time they have seen you with this thing on, seeing as you got back late as hell the night prior.

You opened the door to the library and it didn’t take but a moment for Twilight to notice you, “Oh! Hello Anon, I wasn’t expecting you.” She said trotting over to you.

“Hey Twilight, to be honest I wasn’t considering doing anything until I did some thinking last night, and wanted to do some… research.” That was the magic word.

Twilight’s smile grew into an excited grin, “Research you say? What topic? What species? What historical event?”

She began rambling off any number of things, while her horn summoned forth plenty of large books with information on random topics. You couldn’t even manage to get a single words in as the books floated around both of you as she kept on going. It wasn’t long before nearly every book was floating around and she was rambling off a fact about something you didn’t give a flying fuck about.

“Twilight!” You shout.

This causing Twilight to look to you, with a blush of embarrassment, “I went overboard again didn’t I?” She asked sheepishly.

“Uh...yeah. I just want some information on Diamond Dogs.” You say to her, as you subconsciously run your fingers along your studded collar.

Her ears perk up at this, while her eyes lock onto your collar, “You know Anon, you never fully explained what happened after those Diamond Dogs took you. All you really told us was that you were captured, roughed up a bit, and let go.”

“Well that was all that happened,” You said with a shrug, “If anything else happened I would have surely told you all.”

“Then how did you get that?” She motions to the collar, “And why were you without your clothes when you came back?” She asked looking at you suspiciously.

“The clothes got torn after a little scuffle I had with a few of them. While this... They put it on me while I was in some kinda cell down there, and the short time they had me working.” You said with a wave of your hand.

“You haven’t bothered taking it off?” She said raising while an eyebrow.

“Hey I convinced them to let me go, and I got used to having it on. That and there's no way for me to take it off. I tried the entire way back here.” You said tugging at it.

Twilight encapsulates it in magic trying to break it off, but found that she couldn’t. She could sense their was a few different spells on it, but she could only feel out the magic of one that was blocking her from breaking the others. She was rather curious and would have to look into the magic signature at a later time, as she noticed you getting a little annoyed with her snooping.

“Twilight. Diamond Dogs. Research.” You says snapping your fingers.

“Oh...right...” She said, “I think we may have something on them. They are kinda like dragons in some respects, seeing as they don’t like ponies all that well, so information is scarce about them.” She said looking from shelf to shelf bringing down books with her magic and scanning over them.

You wait patiently scanning the shelves yourself as you try to find the information. Though after about an hour or so, you both came up with nothing. Afterwards you said your goodbyes to Twilight and headed off towards your home, or so that is what you made it look like.

“So it looks I am only gonna be getting some information from the source.” You say making your way to the Everfree, and heading toward the Diamond Dog’s territory to get your answers.

“What are you doing back here?!” Roxy growled as you were dumped in front of her by the sames ones that carried you off when you were kidnapped the day before.

You rolled your eyes and quickly stood up, “Hey Roxy I just wanted...”

“I don’t care what you wanted! You have one purpose, and is to come to when I need to get off!” She barked jabbing you in the chest which sent you onto your ass.

You grunt as you rubbed your sore rump, “But wait...how...”

“If this thing works correctly.” She said grabbing your collar and yanking on it choking you a bit, “It will glow when I want you to fuck me. You are nothing more then my toy to play when I want, not when you want to get off. Now get lost!” She barked.

With a snap of her fingers, several Diamond Dogs in armor rushed from the tunnels and started growling and barking at you. You couldn’t argue with her seeing how she could lay you out on her own if she wanted to, so you quickly threw up your hands surrendering, doing as you were told and leaving. As you left you heard Roxy whistle, looking back you see it was for the armored dogs to go back to where they came from, and she herself started heading back underground.

You sigh and shake your head as you make the trek back to town, “Well pointless to dwell on that.” You tell yourself.

You touch your collar, “Might as well wait.”

Not a full week went by before your collar began glowing for the first time. It took you a moment to remember what that meant but once you made your way to Roxy’s terf. Once you arrived you headed to the room you had your first romp with her, and she was already there waiting. Her rear on full display, those ample cheeks giving a small bounce with every shake.

“You know why you are here. Get to work!” She ordered smacking her rear causing it to jiggle seemingly non-stop.

Your pants tightened instantly.

This went on for several months, and would never be on a regular schedule, and each time was just as good if not better than the last. Sometimes you both would go for hours, and each time you both would be left spent. Though you both were just ‘friends with benefits’, or as she would call you her ‘mate’ or more so ‘fuck toy’.

Yet all this came to halt near the end of winter into the spring months. You hadn’t been called to pleasure Roxy for a few weeks. At first you just brushed it off, you didn’t really care if you went to see her or not. Granted, something in the back of your mind keep nagging you to check up on her, so after a few more days of this feeling you gave in and went to check on her.

You look around and find that it seems pretty barren around. Every other time you had come here, you would see some shapely figures working hard on mining gems. Yet as you looked around you saw nearly no one, minus a few of them in the distance wondering around looking lost.

“Hey!” You call out trying to get their attention.

Their ears perk up at your voice, and they all turn to you. The look in their eyes sends a shiver down your spine, it was rather unnerving. They advance toward you, licking their lips, and eyeing you up like a thick slice of meat.

“This can’t be good.” You say backing away from them as they near you.

With them so close to you, and with their being so many, you catch a whiff of musk emanating off of them. You nose simply twitches from it as you focus on getting away from them, which grew increasingly difficult to do with your mind slowly hazing.

“Why do you look so scared~?” One of them say to you as she licked her lips while her eye locked onto your crotch.

“We are just looking for a little fun~” Another said raising her thick rump in the air and giving it a shake, making it bounce a little.

You were at a lost for words, yeah it would have been nice to have a little fun but Roxy made it clear to you what would happen if you try to fuck anyone else in her pack without her say so. Which you had thought about but never asked or really had the urge to. You shiver at the thought of what these girls wanted to do to you, and quickly make a mad dash down a pathway, looking over your shoulder to find they were keeping pace with you with ease.

You only managed to stay away by constantly changing directions from tunnel to tunnel and causing them to trip up. You manage to lose them as you look ahead and see an all too familiar door. You jump in and close to door panting as your catch your breath, which wasn’t easy considering you just jumped into a room that smelt like nothing but musk and sex. You look up to see the Diamond Dog you were looking for standing over you glaring daggers into you.

“WHAT THE HELL ARE YOU DOING HERE!” She barks at you, clearly pissed.

You wince hearing her tone, “Well I was just wondering why you haven’t called me in a few weeks.” You say rubbing the back of your head as you stood up.

“There is a reason for that! And why the hell would you be worried about me not calling you?!” She said slamming you against the door, getting muzzle to face with you for a second causing you to get smacked with the smell of her sexual arousal.

You blush and feel you pants tighten even more so and the haze growing stronger, “I wasn’t worried...just...”

“It doesn’t matter, you have to leave.” She said letting you fall to your feet, “I didn’t call you because I couldn’t risk you being here...”

Yet her words fell on deaf ears as her scent began to mess with you head, the haze having completely taken over. Your eyes focused on her rump that bounced and jiggled with each step she took from her pacing across the room. You found yourself standing up and walking toward her, she hadn’t noticed your movement as you walked up behind her.

“Someone seems a little...anxious...” You say as you quickly grab her fat ass and mold it between your fingers.

She gasp feeling your grab her sensitive plump rear, and her cheeks light up bright red. She shivers and moans as you feel up her rump, lowering your face down between those luscious cheeks taking in more of her scent. The strength of it made your head spin more and a powerful lust overcome you as you spread her round rump and dived in lapping at her tight puckered hole.

“AH!” Roxy gasp as she felt your tongue licking away at her, “You bastard!” She pushes her rear back onto you and lets out a moan as you tongue enters her.

You spank her ass feeling the ripples over the sea of fast of thick muscle move under your hands as you kept exploring her insides. She let out moans and groans as you spread her cheeks farther apart, her lower lips getting more moist as your worked her ass. The fact your face was surrounded by those bountiful cheeks feeling your vision made you both hornier than before.

Her dripping snatch radiated some serious heat as her arousal increased, and she became more and more needy. Her groans turned into growls as he thrust her rear back making you fall back onto the bed. You look up to see those planet like cheeks hovering over you, that seem much larger as they crashed down on you. You vision was blocked again, and what you could smell, taste, and feel was all worth it.

“Enjoying it now?” You growl just barely audible from under the oversized doughy flesh of her ass.

“Shut the fuck up and start working!” She growls as she tears off your pant freeing your cock.

She grinds her hips back on you as you pleasure her ass and dripping snatch, making her moan before she focuses on her prize. She eagerly lapped at your member, enjoying the taste of your manhood that throbbed against her tongue. You groan into her cheeks and buck your hips from the pleasure which only grew as she wrapped her lips around you and began bobbing her head.

“Oh fuck!” You give a muffled growl as you thrust into her mouth more, but your hip are quickly restrained by her claws digging into your legs.

You move down and attack her clit sucking on it and giving it light nibble. Roxy’s eyes shot open as she let out a loud howl as she arched her back. She grinded harder on your face, while she takes a paw and starts jerking you off rapidly wanting a taste of what she was gonna be filled with. You both let out lustful growls as you both reach your orgasms.

Roxy tail shoots up as she squirts her juices coating your face, the taste seemed sweeter than it ever had before. This caused your sexual drive to increase and your member start spasming in her grip as your fired your seed into the air. Roxy quickly lowered her head and caught every blast of cum you gave, giving off lewd moans as she swallowed down every drop of seed she could.

You both felt something wash over you as your orgasms began to fade, a more feral need. Whatever Roxy had been previously worried about, she didn’t seem to care about anymore. And you felt a secondary sensation rush through you feel as if your teeth slightly sharpened, your nails extended, and your sense heightened. The matching collars you both possessed began to glow and resinate as the feeling of lust and the urge to mate grew stronger within you two.

With newfound strength you grab Roxy around her waist and toss her large form off of you, and on to the other side of the bed. You waste no time positioning yourself over her and pinning her to the bed, grinding your rock hard member between her cheeks. She groans a bit before turning her head growling back at you and struggling to free herself from your grip. She tries to bite you or get you off of her, to show she will not submit so easily.

“Get off me you mother fucker!” She barks thrashing about wildly.

“I think it is time I show you who is the real Alpha.” You say baring your sharp teeth and biting down on her neck.

She yelps and a shiver runs down her spine. Her struggle lessens but she is still trying to force you off. You respond by digging your teeth in deep piercing her skin, making her cry out before it faded to a whimper as she slowly began to submit.

“Good girl~” You said in a husky tone after you have withdrawn your teeth.

“Fuck you...” She says in a small needy whimper.

You smirk and spread her cheeks apart giving you an unobstructed view of a rather familiar sight. You lick you lips as you gaze upon her tight puckered hole, and her snatch dripping and giving off great warmth.

You line yourself with her dripping pussy and thrust into her, you both let out howls of pleasure. The heat and slickness of her passage made you start panting and waste no time pulling out and thrusting back into her. Roxy moaned loudly her tongue starting to hang out of her mouth as you repeated the movement over and over again.

You let out a snarl as you picked up the pace, your hips colliding with your bitches bouncing ass. You take the massive mounds into you grasp molding them as you plowed her heated snatch. She panted and moaned like a whore as you fucked her and couldn’t resist thrusting her ass back against you.

“Someone seems to be enjoying it more and more.” You growl and spank her ass your ears twitching as she whines in pleasure, and you watch the ripple travel over her fat ass.

“AH~! J-J-Just shut up and...mfm~!” Her words are replaced but moans and gasp as you pinch her clit making her splash her juices over your.

“Not so tough now huh?” You said before groaning as she clenches on you as her second orgasm rocks through her body, “Fuck you making it hard not too...” You let out a loud groan as you cock starts to spasm.

Even after her incredible orgasm Roxy’s eyes shoot open as she feels your first blast of cum. She moans loudy and grinds back onto you as you as you shoot more and more of your seed into her. Once you finish Roxy is panting heavily as the more intense burning sensation in her nethers had be reduced but was still present. She shivers as feels you pulling out of her dripping entrance, and looks over her shoulder and get wide eyed seeing your member still hard.

“Even after that...” She manages as she slowly lifts herself up and her face is burning red.

You smirk and give her a devious look, “You should know how long I can go...and we are far from done!”

With quick movements you force her onto her back, and quickly pounce driving yourself into her messy pussy. She gasp loudly as you enter once again and story pounding her, turning her into a moan sweating and panting mess. She was beyond caring about the consequences of what could happen, she just want more until she couldn’t take any more.

“AH~ Harder~!” She shouts as she puts her paw around your neck.

Your ears perk and you exchange speed for power and slam into her, you cock hits her cervix each time. Making her scream louder and beg for more as she snatch clenched down on you, her moist entrance gave you other worldly pleasure. You always enjoy when you two fucked but the near animalistic roughness of her claws digging into your back, the mix your scent in the air made it all that better.

You look down and her sweat matted fur, the drunken look on pleasure on her face, and her large bouncing breast. You were always and ass man, but you could always appreciate Roxy’s other assets as well. And you could feel her thick rump against you thighs as you fucked her senseless.

“Oh fuck!” She shouts as a bolt of pleasure traveled up her spine, you could feel her convulse around your member.

You kept your thrust deep and your movement methodical as you drag her orgasm out, and manage to bring her to another one rather quickly. You manage to hold yourself back, even with the heat of her dripping cunt was surrounding your member with each time you plunge into her depths. You feel another climax approaching once again, and you refuse to pull out once again.

You bite down on her exposed neck, and she claws dig into your back as your slam your cock hitting her cervix and making her climax once again. You howl as your cock pumps fresh seed into her already messy pussy, filling her womb to the brim with your seed. Once both your orgasms faded Roxy went limp, panting as you slowly pull your member out of her.

“Best fuck yet.” You say rolling your shoulders, not aware of the searing pain from where Roxy’s claws pierced your skin.

Roxy was unable to speak, her mind seemingly lost over everything that had just occurred. She couldn’t care less about the consequences she would have to face, she loved the feeling of the cum inside her. Some leaked out of her abused cunt, creating a small puddle underneath her. Before she knew it her began to flutter close, but you weren’t having any of that just yet. Roxy yelped once more as she was forced against the headboard of bed.

“Now what would this be without enjoying more of your fat ass?” you said smugly as you slapped her ass making it bounce and jiggle wildly.

Roxy moaned lustfully, “So good~” She pressed her ass up against you hotdogging your cock between her cheeks.

You slap her ass again before spreading her cheeks and pressing your tip against her tight anus, “One final filling for ya.” you say as you thrust into her.

You both groan as you spread her out, pushing your cock in as deep as you could. Once you were fully buried inside her your grab her pillow like rear once again.

“Someone has put on a bit more weight. In all the right places.” You say with a groan as you enjoy the warmth of her thick booty against your pelvis.

Roxy growls a little at this, but it turns into a groan as you give a small buck of your hips, “Fuck...did you get bigger?”

You only respond by giving her tail a tug, making her freeze up before you pull your cock out and slam forward. As your hips collide with her ass, you watch with a amused gaze as ripples traveling along her plus sized derrière. You get into a rhythm your cock driving deep into the moaning diamond dog.

“Still as tight as ever.” You said lustfully as you enjoy hearing her moans, and the lewd slapping of your hips against her fat ass.

“Mfm~!” She couldn’t form any complete thoughts, she gains more pleasure as her errect nippes rub against the headbored you had her forced up against.

The room was now overflowing with the smell of sex and lust as you plowed Roxy, making her a drooling and mumbling mess. Yet it wouldn’t be much longer as you felt an all too familiar feeling growing down below. Your sharp nails dug deep into her plump butt as you cum deep into, Roxy moaned and panted as she felt your seed flood her hole, so much so that it leaked out around your cock.

Roxy legs were weak, and the only thing keep her up was you. As you pull out she slowly slides down onto the pillows before, panting and her eyes closing as she fainted from all the immense pleasure. While you stood there grinning as you eyes her rump, cum leaked out of her ass and pussy like a waterfall, proud of the work you had done of claiming her as yours.

“I will see you again soon Roxy.” You chuckle as you exit the room.

Completely unaware of what transpired.
