Prologue

Pinkie Pie screamed "Happy Birthday Zipporwhill!" There was cake, drinks, streamers, balloons, confetti, gifts and people everywhere. It was a classic Pinkie Pie party! Pinkie Pie gave Zipporwhill a big hug and said "You're nineteen! Just two more years and it will be legal for you to get absolutely fucking smashed and ride a random dude's dick!" Some people chuckled awkwardly while others scowled at her, sex wasn't exactly a traditional subject to bring up at a 19 year old's birthday party.

Zipporwhill rolled her eyes and said "I told you Pinkie, I'm not into guys, I wouldn't even let a girl strap-on fuck me unless I was feeling particularly generous, which I'm not, ever, so fuck you."

Pinkie giggled and said "Well in two years, you can say "fuck you" to me and enjoy a nice cup of cider!" Then winked as she went to go mingle with some of the other party-goers, among the party goers was Scootaloo, Zipporwhill's girlfriend.

Scootaloo walked over and kissed Zipporwhill on the lips before saying "Happy birthday babe"

Zipporwhill did give a little smile, she wasn't totally heartless and she adored Scootaloo, "Thanks honey" she said. Another person at the party was Fluttershy, but she wasn't focused on the food or the drinks, she wasn't enjoying the balloons and confetti, she wasn't even mingling with other people. She was simply staring at Ripley, Zipporwhill's dog and wondering to herself "I wonder if there's a secluded place somewhere that I can get him to fuck me?"

Getting Bitched

Fluttershy just couldn't help herself, she had already almost been caught having fun with the horses at Applejack's most recent family reunion and now she was musing on the idea of finding a secret hiding spot where she could get her hands, lips, pussy and ass on some delicious dog dick.

Fluttershy was looking around the place, trying not to look suspicious when she noticed that nobody was going in to the upstairs area except for those who needed the toilet, maybe she could sneak into Zipporwhill's room and have a little fun in there? She was horny enough to find out, she hid herself in a corner of the room and dipped her hand into her panties, after rubbing her pussy a little she pulled her hand out to find it suitably wet for what she was about to do. She hustled and bustled through the crowd of guests until she reached Ripley, the crouching down she made it appear as if she was simply stroking him while she pressed her wet hand up against his nose, then whispering into his ear "If you want more than just the smell of a hot aching pussy, then be a good boy and follow me upstairs, then you can make me your bitch for the day".

Ripley was already excited as he followed Fluttershy, slowly becoming more erect the closer they got to Zipporwhill's bedroom. As soon as they were inside, Fluttershy checked the coast was clear and then gently shut the door before turning around to see Ripley with his tail wagging and his cock throbbing. Fluttershy giggled and said "It's nice to see you're ready to go boy..." she walked up to him then got on her knees and tried to gently coerce him into lying down on his side as she said "Before you get to breeding me like I'm the last bitch on Earth, how about I give you a nice blowjob first, hmm?" Ripley's panting gave Fluttershy all the answers she needed, Ripley was on his side and waiting for Fluttershy's soft lips to wrap around his painfully hard erection. Fluttershy wasn't one to keep a good dog waiting, she lay her head down right by Ripley's crotch and in one swift movement slipped his entire cock in her mouth, making him let out a small yelp.

His cock was slightly longer than it looked and she gagged a little as the tip poked the back of her throat, she was practicing her deep-throating skills in her own time, but she hadn't quite perfected it yet. Fluttershy massaged Ripley's full and heavy balls and she moved her head back and forth, sucking him with an almost elegant ease, swirling her tongue around and becoming almost entranced with the pure sexual thrill of tasting a dog's cock, it was a flavor she couldn't get enough, like the world's tastiest lollipop. So focused on her blowjob was she, that she didn't notice the sound of the door opening and shutting as someone walked in on her giving Ripley the best treat a dog could receive.

Zipporwhill simply stared at the spectacle, when walking into her room to retrieve her phone, the last thing she expected to see was a grown woman absolutely going to town on her pet. It was only a few seconds before Zipporwhill gave a very loud and clear *ahem*, Fluttershy's eyes flew wide open and she removed herself from Ripley's cock, much to his chagrin and turned around to see Zipporwhill with an expectant look on her face.

Fluttershy went "Uumm......this isn't what it looks like?"

Zipporwhill smirked and said "Convincing! So you weren't just, oh I don't know, blowing my dog like your life depended on it?"

Fluttershy conceding defeat and without any trace of panic said "Alright fine, I was sucking off your dog".

Zipporwhill said "Good to know, didn't realize you were quite literally such a bitch Sluttershy"

Fluttershy shrugged and said "Well, what you gonna do?" Then immediately went back to sucking Ripley's dick. Zipporwhill thought about that statement for a moment... what was she going to do? Tell someone? What good would that do? Eventually she just thought to herself "fuck it" and locked the door, she was going to join in. Zipporwhill went to her cupboard, opened it and pulled out a small chest that contained all of her sex toys, true she didn't let anything inside her, but that was just the thing, nobody could penetrate her. That was the rule. So as long as nothing entered her body, she could do whatever she liked.

A Girl and Her Dog

Zipporwhill pulled out a toy that she just loved to use, a light blue strap-on. She put it on around her waist, then surprised Fluttershy by getting on her knees, burying her face in between her ass cheeks and instantly sucking on her asshole. This was incredible timing because as Fluttershy got the shock of her asshole suddenly being tended to, Ripley let out a small howl and blew his hot doggy load into Fluttershy's mouth, his spunk flooding her tongue as it pooled in her cheeks. Fluttershy had no choice but to swallow all of his warm sticky cum and allow his knot to deflate before letting his cock slip out of her mouth, then with a smirk she looked back at Zipporwhill and said "I see the birthday girl wants to get involved, huh?"

Zipporwhill nodded before pulling away and giving Fluttershy a smack on the ass, then she lied back on her bed and said "Get your fucking ass over here, Ripley is still hard so he can have your pussy while you bounce on this cock. Seriously, if it wasn't so awesome having a pussy I'd swap it out for a massive dick and set of balls in a heartbeat".

Fluttershy giggled and climbed onto the bed, then facing away from Zipporwhill, she angled herself so that Ripley could fuck her in the missionary position even while she was having her ass pounded. Fluttershy lowered herself down and with Zipporwhill's help slid the entirety of the strap-on up her ass, she patted her wet pussy and said "Come on Ripley! Here boy!"

Ripley who had become slightly soft went back to full hardness again at the thought of entombing his dick in Fluttershy's needy pussy. He hopped up onto the bed and wrapped his legs around the curve of Fluttershy's hips, then after some careful guidance his cock managed to push its way past her folds and into her hot moist vagina, Zipporwhill similarly grasped onto Fluttershy's torso with both hands, they were all ready to fuck.

As soon as Ripley starting pumping away at Fluttershy's pussy, Zipporwhill immediately started pushing her hips upwards to fuck Fluttershy's ass, using the momentum of the springs in her bed to bounce her hips back up on every downwards movement, making the bed squeak. Fluttershy went cross eyed and her tongue hung out of her mouth, bordering on full aheago face, she had never been double teamed before, the experience of having her ass and pussy fucked, not to mention one cock was canine while the other was human, her body responded by simply flooding Fluttershy's brain with dopamine and triggering a cascade of orgasms throughout the session.

Fluttershy felt herself almost going insane with pleasure, how had the thought of being fucked by more than one cock in multiple holes never occurred to her before? It was fucking awesome! She groaning loudly with occasional interval of what Zipporwhill assumed was Fluttershy attempt at words of some kind, Zipporwhill reached her hands further up and groped Fluttershy's tits, squeezing them, pulling and twisting her nipples. The intensity of Fluttershy's repeating orgasms increased, she didn't know how much more she could handle, Ripley was still going and his knot had barely started to grow, Zipporwhill was only getting harder and faster with her fucking if anything, Fluttershy wasn't sure how much more her body could cope with before she lost consciousness from over-stimulation and passed out, she desperately didn't want to faint whilst getting the best fucking she had ever had in her life!

Fluttershy somehow grasped onto the faculties in her mind required to keeping her awake, clinging on to her sanity as every depraved sexual fantasy played out both physically and mentally, her brain was alight with reactions beyond comprehension. It all came to head as Ripley howled and rammed his knot into Fluttershy's pussy, a pumping a second much larger load into her tight, clamping and absolutely drenched fuck hole, whilst Zipporwhill used all of her muscle power to give one powerful thrust upwards, the strap-on reaching the deepest point in Fluttershy's ass it could reach. Before Fluttershy finally gave up and allowed to sleep to claim her, simply collapsing with Ripley stuck in her pussy and Zipporwhill, slightly crushed and unable to move under the weight of Fluttershy's body.

After the birthday party was over, everybody left, nobody had noticed that Fluttershy and Zipporwhill had seemingly disappeared for a quick and unexpected fuck that involved her dog. Before Fluttershy left Zipporwhill said "Hey, I'm currently in a committed relationship with Scootaloo, so don't expect what happened up there to become a regular thing. However, if at any time in the future you wanna come round here and fuck my dog? Just do it" she smirked.

The End
