Friends Bonding

Previous Chapter

Seems like Rarity has finally gone and done it. She got too carried away with her masturbating and moaned out from lack of control. Knees were weak and she was shaking, Rarity tried to buckle her blue jeans back up but the immense trembling and the extreme tightness of them was a difficult thing to accomplish. But it was more than the physical challenges that were stopping her from getting the hell out, something in her mind wants this opportunity. To get caught for whatever twisted sick reason.

Fluttershy couldn't stand up from the intense rutting that she just took from her dog, and yet she tried her best to crawl over to her bedroom door. Dedicated to seeing for herself who was behind the door. Hoping it was just her imagination playing tricks on her mind, that her deep dark secret could be protected for another day.

"Stupid! Stupid! Stupid!" Rarity repeatedly thought to herself. The nerve of her, fingering herself to not only dog on anthro pony relationship, but to her own best friend no less. However, Fluttershy struggling to get to the door was enough time for Rarity to make her escape. But there was just something in her mind, her soul telling her to stay. Rarity knew the possible consequences of being caught, but for whatever reason, she's staying put.

A nervous hand poped out the opposite side of the door for Rarity, nervously opening it only for Fluttershy to discover that Rarity was sitting right behind it, looking like she saw a ghost. To add more confusion to the situation, Rarity had her jeans undone with her left hand halfway through her pussy.

"RARITY!?!?" Fluttershy yelped. "F-f-fluttershy, I-I can explain, darling!" Rarity exclaimed.


After about 30 minutes of explaining later, they came to the conclusion to not ever speak of this to anypony. Not only did Rarity explained how she ended up caught with her pants down, but she also voiced her new awakened fetish for bestiality and wanted to test it with Fluttershy as her mentor. Fluttershy was hugely embarrassed at first, but she soon realized how awesome it is to have somepony else to share this dark secret of hers with but to also share the same fetish together. And as a plus, it's with one of her best friends no less.

"So... are you sure you want to do this with me Rarity?" Fluttershy asked in concern. "I-I mean, I would love to have you do... this with me, b-but only if you're comfortable with it."

"Darling, I'd be grateful for your assistance with this. To be honest, it's not the first time I thought uh... doing it with a dog." Rarity paused for a bit. "I've read about it before in my super-secret romance novels I keep in my closet. Although it's been a while since I've had this 'topic' in my mind. Seeing you go at it with Rex made me confident that I can do this too."

Fluttershy was at a loss for words. She'd be honored showing Rarity around the ropes. Sharing this with her will make it extra special too.

"Well gosh. Thank you Rarity."

"So. Shall we get Rex?" Rarity happily suggested, pointing to Rex sleeping on his little bed.

"Well actually, he's a little tired right now, but don't worry. I know plenty of doggies that can do the same. But since it'll be your first time, I'll fetch one of them for you."

Rarity immensely blushed from the mention of multiple canine partners. Just imagine, a group of mutts huddling around, claiming her as their price as if she's just some fucktoy to them. Some of them not even properly cleaned while others are right out filthy. Having their uncleaned dog dicks shoved inside every available hole she has.

"Um. Rarity?" Fluttershy asked, nudging on Rarity.

"W-w-what? I mean uh, yes Fluttershy?"

"Are you okay?"

"Why yes, o-of course. Sorry, darling."

"Oh, okay. Anyway, whenever you feel uncomfortable, let me know. Okay?"

"Understood."

"Oh yeah and um..." Fluttershy stammered. "I might uh, get a little carried away with what I say, you know, for foreplay. Is that alright with you?"

"Of course, darling. Now, go get one of your cute dogs here and show me what you got."

With that settled, Fluttershy whistled and called out the name "Courage". Fast approaching footsteps can be heard from the bedroom, making Rarity a little anxious. She has no doubt what she's about to do but the upcoming dog sounds big already and very excited.

A husky reveals itself from the shadows and cheerfully jumps in the room from anticipation. He looks bigger than Rex too, so this might be a little bit more challenging than what Rarity originally thought.

"Whoa now big boy." Fluttershy said, Rarity just sat on the floor patiently. Courage was running circles around the two anthro ponies, Fluttershy was giggling at the sight of his happiness. She may be a dog fucker but she still cares deeply about how her animal buddies are feeling.

"Alright, Courage. Sit." Fluttershy commanded. Courage was more than happy to oblige and so he sat right in front of the two sexiest ponies he sees.

Courage is especially attracted to Rarity. Her vibrant purple mane and soothing white coat resemble almost that of an angel. The proof is his semi-erect red rocket. This caught the eye of Rarity, causing her to blush a heavy red from seeing a canine dong so close, not looking away for a sec. The dick is no doubt a bright red color with a nice juicy knot at the base, not to mention the many sporadically looking veins from red to purple. But despite the nice looking cock Rarity is gawking, she took noticed of the grime that's on it.

"F-fluttershy darling. Is that... smegma?" Rarity nervously asked, knowing full well what it is though.

"Oh yeah. Sorry, I haven't had the chance to wash Courage yet. If you want, I can get some other pet else."

"No no. It's fine, I want the full experience."

"Um, okay. If you really want to."

Courage couldn't contain his excitement with the new pretty lady in front of him so he went ahead and licked Rarity's face.

"Good boy Courage. Give that bitch a good licking."

Rarity couldn't believe what she just heard. She did accept to Fluttershy's foreplay agreement and she's all for it, but dang hearing Fluttershy out of any other pony speak like that is so wow. She liked what she was hearing.

"Go on slut, kiss him back. You should return the favor." Fluttershy ordered, and so Rarity followed her command.

Nervous at first, Rarity opened her mouth anyways. Once opened, the invading tongue dominated her mouth slobbering all over Rarity's mouth, she tried to fight back the foreign tongue with her own, but only encouraged the dog more, thus pushing on. Rarity wouldn't give up without a fight, so she pressed forward as well, ignoring the smelly dog breath she's letting in willingly in her mouth. Courage must have been licking his balls before this, she just knows it. After all, being a town slut does leave you with a lot of experience. Not like it bother her, in fact, it just aroused her more. A fucking mutt doing whatever it pleases to Rarity with no concern with what she wants, it's primitive and she loves it.

Courage was getting harder and so with that, Rarity broke the kiss. Leaving a string of saliva still connected from their own lips. Rarity didn't know swapping spit with a dog could be so hot, it wasn't just Courage getting aroused, Rarity's dick pocket is on fire too.

"How did it taste, slut?" Fluttershy asked.

"Magnificent."

"Good. Not like I was expecting anything different from a harlot such as you."

Fluttershy is really getting into this role. Rarity doesn't mind, she loved the names she gets called on a daily basis. It's half the fun.

"I suppose you wouldn't mind polishing Courage's cock would you, Rarity?"

"No I wouldn't darling. I would not."

With that said, Courage laid on his back awaiting his cleaning service. He knew what was coming next. Before Rarity made a move, Fluttershy went ahead and positioned herself to where Courage's anus is at. Without hesitation, she went down on him and started rimming his asshole. Her tongue was spinning in circles, wetting the surface area first, then she went in for the target and penetrated her tongue into Courage's anus. Courage was moaning with pleasure, and it's up to Rarity to further enhance Courag'es experience. Rarity has done this plenty of times with customers but those were other ponies, this is a dang dog. And yet as if it was natural to her, she didn't instinctively gag at the sight of this.

Rarity reached for the dog's dick for a feel. It was warm, she can feel the pulsing of the red giant and she loved it. The meaty textured dog bone is one to remember. Before stroking, however, she figures she'd get rid of the gunk first. Rarity went ahead and leaned her face closer to the dog's huge penis and gave it a bit of a sniff. It's sweaty, the musk was already strong before but now it's stronger, the stench was getting to her head just like last time. She gave one lick, then two, then three, each streak of smegma was disappearing from Rarity's service and she Courage loved it. It just evolved from a few licks to now consecutive licks and some sucking.

"That's right whore, clean it up like the living fleshlight you are." Fluttershy mustered out saying only to go back to rimming Courage's asshole. Ironic I know.

Rarity was moaning in pleasure. Being brought down to this level by this mutt was so fucking hot to Rarity, it was the ultimate fantasy. Fluttershy was enjoying it too and would encourage Rarity more if she wasn't busy with the rimjob.

"There. Clean as a whistle." Rarity said.

"Good." Fluttershy said, wiping her chin from the heavy amount of saliva she produced from rimming Courage.

"Fluttershy, could you be a dear and do Courage's balls as well?" Rarity asked.

"Sure. Just let me just catch a breath-" Before Fluttershy could finish her sentence, Rarity went ahead and pushed Fluttershy's head down towards Courage's musky balls. She didn't object though, she just automatically started on messaging and sucking on Courage's sweaty balls in her mouth.

"You're not the only one that can be rough, sweetie." Rarity smugly says as she positioned herself for the next step of Courage's service. Rarity was on her back, dangling her beautiful soles on top of Courage's face.

"You want this boy?" Rarity teased. It only made Courage whine in compliance.

She's about to give Courage the best footjob of his life. Rarity gently placed one foot under Courage's big meaty cock and the next foot on top. It felt so warm and lively, feeling Courage squirm was fun too for Rarity. Her nice tender feminine feet started moving, slowly at first. The dog couldn't help but pant from excitement, and so was Rarity too. She started massaging her right breast with her right hand while she plays with herself using her left hand. As an experienced whore, she had no problem multitasking different parts of her body to do different actions.

Rarity's footjob on Courage started getting a little bit faster. Not only is the shape of Courage's cock fun to look at, it feels fun too. She also hasn't forgotten to rub the dog's knot too, her feet wrapping around that big juicy ball is so amusing to her. You can hear the slimy sounds echo around the room as she strokes him faster and faster with his feet. Fluttershy pulled her head up for a second to breathe only for Rarity to plunge her back down to the canine's ballsack using her left foot. Fluttershy was supposedly the one in charge but it seems like she's going to need some practice on that later on. With that aside, Courage is at the brink of cumming, and Rarity can't wait for it any longer. She goes at top speed with her feet while still maintaining to fingering herself.

To Rarity's success, Courage made his final moan of pleasure before releasing his seed all over Rarity's feet and some on Fluttershy's hair. The dog was drunk with happiness as you can tell by his relieved baby batter. Fluttershy finally got the air she needed and Rarity was scooping up whatever cum didn't fall on her feet.

"Good boy, Courage. You're such a good boy." Fluttershy cheered while rubbing Courage's stomach.

To Fluttershy's surprise, Rarity presented her left foot to her, covered in Courage's spunk. Suggesting for her to clean up the mess Courage left on it as her treat

"Eat up, darling, We wouldn't want this delicious cum go to waste can't we?" Rarity said with a smug face on her look.

Fluttershy followed along and started licking Rarity's foot. The cum was everywhere. She tried her best catching it all in her mouth from between Rarity's toes, the cum running on her slender arc, and some on her ankle even. The sparkly purple pedicure she has creates a very interesting flavor inside Fluttershy's mouth, adding more variety to her little snack. It had a hint of grape to much of her pleasurable surprise. As for Rarity, she got her fair share too with her right cum covered foot. She licked all across the bridge of her foot, to the ball, through the long arc, and back to the heel. Sharing the same treat her dear friend Fluttershy is having. Her foot was now cleansed from cum and now replaced with Rarity's saliva instead.

It seems like Rarity missed some doggy cum on her chin somehow, so Courage was kind enough to capture the string of cum dangling from her face with his mouth and spat it back into Rarity's mouth. And like the good girl Rarity is, she swallowed all of the sperm, including the slobber that came with it.

"Thank you, Courage. You're such a gentleman." Rarity said.

Courage smooched Rarity right in her mouth as a gesture of his gratitude. It took a few seconds before he broke the kiss, face to face with the bitch in heat.

"Alrighty now." Fluttershy said, licking her lips for any remaining cum on her face. "How about I let you have the floor for yourself since it looks like you've got things handled. I'll watch from a distance and just watch." She suggested.

"You're too kind Fluttershy. I'll try my best." Rarity replied back, following it with a wink.

Rairty just laid on her back and patted her cunt as an invitation to Courage. With no doubt in Courage's mind, he hopped on top of Rarity, presenting his massive member to her. The veiny cock was laid on her stomach, easily reaching past her belly button. His dog meat was warm on her belly, wet, and pulsing from affection.

"Oh you tease. Shove it in already! I want you to breed me and make walk funny for a week!" Rarity roared. She wanted to feel his schlong and split her apart.

Those were the words Courage was looking for. He loves playing with his toys. Eager as well, he inserted his dick at last with great power, forcing only half of his cock inside Rarity.

"Oh fuck!" Rarity screamed.

Fluttershy was really enjoying the show, so she went ahead and laid down on her bed and started to play with herself at the sight of her friend fucking a dog. She soon realized that her fingers weren't enough so she reached the drawer next to her and pulled out a foot-long dildo in the design of a dragon. It was neon green with a rubber layer finish with a hard inner core. The play toy was bendable to an extent and still hard when shoving it in, simulating that of a real living dragon. She started with the clit, not wanting to reach the climax yet. The pointy tip of the dildo was already sending waves of pleasure to Fluttershy.

Rarity was having a blast of her own. Courage didn't start slow, he may have started with half his cock inside Rarity but that ended quickly when he rushed deep the caverns all the way until the knot strikes with the outside walls of her pussy. From there he repeatedly shoved his cock inside back in and out with great force. Sounds of slaps were made from the clashing of Rarity's large ass and Courage's hips. Courage was picking up more speed, rapidly thrusting his dick inside his new favorite fucktoy, making Rarity's mane messy because of this but she didn't care, only doggy cock. Her large breasts were bouncing rapidly from the fierce pounding and her pussy was becoming red from the fast blows. The intense musky steam in the room strengthens and sent stronger mating signals to all of the animals in the room. If it wasn't for the closed door, the aroma would've surely traveled all around the house.

"Ah yes, fuck me harder! Make me your bitch!" Rarity roared.

Courage took those words for motivation and upped his game more. He was now at max speed, making his over-glorified toy scream in pleasure. Dog slobber was dropping from Courage's mouth and fell on Rarity's face and jugs. Some were even caught in her mouth but she didn't care. She loved it.

Rex was slowly awaking from his disturbed nap. The screaming in the room and musky odor in the room was too much for him. To his surprise, a never before see ponygirl was being mounted on by Courage while Fluttershy was in the corner masturbating to it. He didn't know how this happened but he does know one thing. He's going to take advantage of it.

To Rarity's shock, he noticed Rex was now awake and heading towards her with a needy wet dripping cock. Fluttershy noticed as well but didn't intervene, she wanted to see how this will go.

"Um, hello darling. How was your-" Before Rarity finished her sentenced, she was stuffed with a dick in need of service. Since her face was turned around in Rex's perspective, every time he shoved his dick all the way down minus the knot, his huge sweaty ballsack would hit Rarity's nose. Stunned at first, she got the hang of it pretty quickly.

It was now Courage and Rex having their way with Rarity. This was quite a show for Fluttershy, vigorously shoving her dildo further and faster now.

Rex was having a hard time holding his nut in. Rarity's experienced mouth was no joke, he already feels like blowing his load in this cum dumpster. He's used Fluttershy's mouth plenty of times but this was totally different. The precision with her tongue was godly and her ability to hold her breath this long is impressive. Rex might not be able to feel Fluttershy the same way again after this. It still won't stop him from using her as his play toy, but he's definitely not going to miss the chance of fucking her mouth-pussy the next time she comes to visit.

Rarity's tears arose, making her face messy from the now messy black mascara. She's at no risk of suffocating but this was at no means easy for her either. She took in every ram from Rex like a pro and made sure to pleasure him with her mouth the best she could. Rex's lustful whimpering was a sign that she's doing good.

Rarity's downstairs apartment was having a blast. Courage pressing in at fast speeds was nothing like she's experienced before. Each thrust sliding through her cervix and hitting her uterus is amazing. Each wave of vibration was like a gratifying scratch to an itch that could have never been satisfied until now. Courage's huge cock was ripping her apart like never Rarity has experienced and she loves it.

Courage and Rex can't hold out much longer, they are coming close to climax. It was evident from their fast panting. The two dogs did their final mighty thrusts before shoving their knots fully inside their new bitch. Rarity wanted to scream but couldn't due to her mouth being overtaken by Rex's knot. Courage's large member fully inside wasn't a help either. Her nostrils were desperately seeking air, trying her best to not suffocate. Rex finally blows his load inside her throat, shooting with great force, rope after rope. She can feel her stomach grow as more cum from Rex rushes in. His cum was too great though, easily overfilling her and even having jizz shoot from her nose. Courage's orgasm wasn't easy to take either, it stuffed her pretty good. Rarity's stomach was bulging out from Courage's huge dick, making it look a little larger from her large consumption of cum. With no more space in, Courage's gushing creamy ooze shot out from Rarity's pussy, just squeezing past his locked in knot. Rarity was releasing her love juices too, her pussy was unleashing so much of her orgasm. So much cum was being spilled on the floor, releasing even more musk odor in the room.

All of this was too much for Fluttershy to hold. She finally reached her limit and started squirting on her large dragon-like dildo. She was so happy for Rarity and couldn't contain her excitement.

Upon relief, Rex's knot softened enough to release it from Rarity's mouth. Dragging it slowly from her tongue and now resting on her face. It's pulsing rhythmically on Rarity's face now as Courage slowly takes out his member from her pussy.

"Thank *gasp* you." Rarity said to the dogs. Although she's now raising an eyebrow to what the dogs are doing.

Courage and Rex position themselves standing among their used bitch. Fluttershy just observed them from afar, she knew what was coming. Rarity had no clue but just stood laying down with her messy face and filled gut, wondering what was next. The two canines each raised one leg and started to release their piss on Rarity's lightened body.

It was surprising to Rarity and new too, but she welcomed her golden shower. Rex was aiming directly at the face and Rarity opened her mouth to accept his refreshing lemonade. It was bitter but not as foul as she thought it would be, not bad. Courage simply sprayed his urine on the rest of her body, coating her with his nice warm love essence as she rubs her busty chest.

This was the final step by the dogs, marking their property. A symbol to show her where she belongs in the class chain, nothing but a cumdumpster and their personal toilet. A marking Rarity has accepted.


It was now sunset. Rarity has cleaned herself up using Fluttershy's bathroom, and now it's just them two in the front of the cottage.

"I never knew you had it in you?" Fluttershy asked.

"To be honest, neither did I." Rarity replied back. Lightly blushing from the performance she showed off her to her friend.

"Don't worry, your secret is safe with me."

"Thanks Fluttershy. But maybe that won't be necessary for the future. Given some time of course." She paused for a sec. "After all, I'm already a known whore in town, so maybe it won't be that different. I'll just have to charge extra for it."

"Oh, well okay. If you're alright with it that is."

"But don't worry, I'll keep your secret for sure, darling."

"Thanks, Rarity, I really appreciate it."

With that said, the two friends exchanged hugs and split apart. Rarity was on her way as Fluttershy watched from the doorstep of her home. One thing Fluttershy did notice as Rarity was walking further, was that the white unicorn was missing her purse that Fluttershy could've sworn she had. Fluttershy ran back to her bedroom to check if Rarity's purse was there only to find Courage humping something. It was Rarity's purse that Courage was fucking and it seems like it's filled with his doggy jizz already.

"Really, Courage? You silly dog." Fluttershy sighed out.

She swooped up the purse from Courage and took a look. It's really filled up with cum, drowning all the contents inside the purse. It seems like Fluttershy will have to return Rarity's purse back sometime later when she gets the chance.

"I guess I'll need to wash it... Or maybe not."
