The door to Fluttershy's cottage slowly creaked open.
”Flutters?” You shouted as you stepped inside the home. ”I got your letter? Everything okay?”
The small bird who brought you the letter flew past to it's nest in the corner of the room, it's work now done.
”Fluttershy?” you shouted again to the seemingly empty cottage.
Then you caught movement on the base of the stairs. Angel Bunny stood there with his trademark deadpan look on his face. He was tapping his foot impatiently.
“Where's Fluttershy, Angel?”
Angel Bunny never seemed to like you. Then again, he didn't seem to like anypony else either. Nevertheless, he guided you upstairs, hopefully to where Fluttershy was. You followed the bunny, carefully as you didn't exactly trust him, to the bedroom.
The situation suddenly reminded you of your first time with Fluttershy. It started with similar circumstances, with Angel leading you to her bedroom, where she laid on her bed, in what was undoubtedly supposed to be a sexy pose. She had chickened out back then before the fun could start, but during the months after that, had warmed up to you. You'd had many a fun night since then, and wondered if this was going to be similar.
Surprisingly, the bedroom was empty. You turned to Angel questioningly, but he didn't even pay attention to you. He hopped his way to the bathroom door and knocked on it, before hopping out, closing the door behind you.
“Anon?” a frail voice came from the bathroom. “Is that you?”
“It's me,” you respond. “Everything alright Flutters?”
You tried the door but it was locked.
“I'm okay,” Fluttershy's muffled voice came from behind the door. “This is just the only way I could possibly go through this.”
“Through what?”
“On the bed,” came the respond.
You didn't seem to be able to get anything more out of her so you walked to the bed. On it was a picture album with the title “Rex” on the cover. You picked up the album, and opened the first page, only to freeze.
“Fluttershy? What is this?”
No answer came. The first photo in the album was of a large dog, a German shepherd, if you're not completely mistaken, who's name you could assume to be Rex. You actually thought you might have seen the dog in Fluttershy's backyard once or twice. The weird part about the picture though, was the fact that the dog was lying on it's back, proudly presenting his impressive canine dong.
You turned to the next page where there's a close-up of the red rocket. It actually didn't look that much like a rocket honestly. It was bright red, slightly bulging at the base, with a more blunt head than you expected, with a protruding tip on the urethra. It makes you feel dirty when you look at it.
You turn the page again and gasp in shock. This picture features Fluttershy as well. A content smile on her face, licking the red flesh.
You want to ask Fluttershy what the hell is going on, but instead turn to the next page. And then the next, and the next. Each photo is more explicit than the last. Half way through the book you come across a photo of the bright red cock rubbing against Fluttershy's pussy.
You'd be lying if you said you weren't aroused.
You continued through the book, eventually flipping through photos of your marefriend actually having sex with the dog, in all possible angles. Once you finally reached the last page, you were uncomfortably hard. The last page was lacking a picture, a written note falling from the book instead.
You put the album down on the bed and picked up the note.
I hope I didn't scare you, Anon. I just couldn't think of any other way to tell you this. I know most ponies think doing these kinds of things with pets is wrong and even disgusting, but I love my animals, and Rex is my favourite. You're not a pony though, and we love each other very much, so I hope you can understand my feelings. Of course I haven't done anything like this with Rex since we started dating, but I felt like you needed to at least know this side of me. I hope you can still love me like before. And I hope you can listen to my request. The last page of my album is reserved for a very special picture, of my very special somepony. Or human. I understand if you don't want to do this, and I promise I'll never even think about it again if you say no, but if you said yes... If you said yes, you'd make me the happiest mare in Equestria.
Love, Fluttershy.
You looked down to the album on the bed, the open last empty page. It was undoubtedly wrong. If you crossed that line, you were sure there was no coming back. Then again, you were in a sexual relationship with a pony, technically an animal. You looked to the note again.
...you'd make me the happiest mare in Equestria.
Wasn't that what you'd always wanted her to be?
You slowly flicked back to the second to last page in the album. A photo of Fluttershy and Rex, in the doggy position. You examined Fluttershy's ecstatic expression, her glowing red face, her tongue lolling out, her eyes rolling up, her wings flared. Your pants got just a little bit tighter.
Love, Fluttershy.
...happiest mare in Equestria.
You slowly walked back to the bathroom door and knocked gently. A meek whimper answered.
“Fluttershy?” You swallowed hard. “I love you.”
A small gasp came from the other side of the door.
“And I want to make you happy... So, I'll do it.”
The lock clicked open and the door cracked open. A large blue eye peered through the crack.
“You really mean it?” she asked in a quivering voice.
You answered with a simple nod.
Suddenly the door exploded open and you marefriend tackled you to the floor with a squee.
“Oh, I'm so happy! I love you, I love you, I love you!”
You smiled happily as you stroked her hair.
“Just one thing,” you interjected, making her look up anxiously. “Can you promise he'll be gentle?”
The bright smile came back.
“Oh, of course he'll be! He's a good boy. Oh, he'll be so happy as well. He's been a bit sad since I hadn't had any fun with him for so long. I'll go get him at once!”
And with that she was gone. You heard the back door open downstairs. She might have rivalled Rainbow Dash in her speed at that moment.
You stayed sitting on the floor, waiting for her to return with your lover for the night.
She did soon come back, giggling at the dog following her, who had his nose buried in her behind.
“So eager,” she laughed. “But I won't be your partner today, boy. He'll be.”
Rex looked to you, turning his head to the side in confusion. He walked past the pegasus to examine you closer, and sitting on the floor, you really realized how big he was. He was as tall as Fluttershy, his nose would be on the same height as your naval, if you were standing. As you were, he was standing above you.
He gently sniffed many parts of your body, before giving your face a long loving lick.
“He likes you,” Fluttershy giggled.
Rex lowered his muzzle to your neck, licking it at first and then gently nibbling on it, making you gasp. The feeling of those large teeth pressing into your skin felt more arousing to you than it probably should have been.
“So frisky,” Fluttershy breathed. “Let's get started then. You should take off your clothes, and start getting him ready. I can get you ready.”
As you stood up to pull off all your clothes, Rex fell to the floor on his back at Fluttershy's command. Standing naked on the floor was the first time you had ever felt embarrassed in front of your lover. Instinctively your hands fell to cover your throbbing member.
“You should get on your knees on the floor and familiarize yourself with him,” she instructed.
You did as told, and pushed your face close to your shaggy lover's crotch. His member was already halfway out of it's sheath. You'd seen canine packages before, other than the photos just now, since dogs didn't usually wear clothes. Still, you'd never seen one up close like this.
It was just as red as in the photos, and had a slight sheen on it you couldn't explain. It looked almost wet. The scent coming off of it was musky, salty, earthy and, most of all, strong. It made you feel dizzy. You carefully poked it with a finger and felt it was as wet as it looked. Your gentle touch made it grow harder.
You wrapped you hand around it and moved it slowly down, pushing the sheath in. Rex gave a soft bark at your actions, that you took as enjoyment. More of the shaft pushed it's way out, growing bigger and harder, to the point you almost wanted to ask Fluttershy if it was normal.
Just as you were about to, you felt her muzzle poke between your butt cheeks.
“What are you doing?” you asked in an embarrassingly high voice.
“Getting you ready of course,” she smiled. “You can't expect to just take him without any preparation.”
With that she pushed her muzzle back between your cheeks, licking over your butthole several times. It felt better than you might have liked to admit. Then she probed you with her tongue, trying to push it inside, making you gasp. You felt her hooves on your rump, massaging you, making you moan.
A whimper from above you caught your attention. Rex was looking at you longingly, and you realized that you had been neglecting him. You started moving your hand up and down again, taking his full balls in your left hand, grabbing them gently.
A particularly enthusiastic lick forced a surprisingly feminine moan from you. Fluttershy's muffled giggle made you blush, and she doubled her efforts to hear you again. You were embarrassed enough already, and wanted some way to stop from moaning out loud. And the only way you could imagine to do that was to gag yourself with the red member in front of you.
It tasted much like it smelled. Strong and salty and dirty. It tasted like something that shouldn't be in your mouth. And that made it so much more thrilling.
Rex whimpered as his sensitive member was enveloped in the warm confines of your mouth. He was obviously enjoying the attention.
Fluttershy disappeared from behind you. Her smiling face came next to you and she giggled.
“How do you like the taste?” she asked.
You emptied your mouth to answer: “It tastes sexy,” before stuffing your mouth again.
Fluttershy snickered. “Good. Try taking it deeper.”
She was surprisingly in her element. She liked to dirty talk every now and then, and while it was sexy, it was mostly awkward. Now she seemed much more confident than usual.
You did as she asked and pushed Rex deeper into your mouth. The tapered head poked the back of your throat, making you gag slightly. A look of worry crossed Fluttershy's face, and disappeared as you smiled to her.
As you got into a rhythm, taking the cock in and out of your mouth, the pegasus trotted to the bedside table. After a short rummage through the cupboard, she returned with a bottle of lube.
You blushed even deeper, if possible. Fluttershy disappeared behind you again, and soon enough you felt the cold lube squirted on your tight pucker. And then a hoof slowly massaging it everywhere.
You fought against moaning once more, until finally the assault on your sensitive behind ended. Your yellow lover sat next to you again and asked you to let Rex out of your mouth. It really was impressive that he hadn't come already.
“Lube him up,” Fluttershy said, giving you the lube.
You squirted a generous amount on the beastly penis, and rubbed it in with your hands. Once the member was sufficiently lubed, you wiped the rest of the lube off on your back door, before turning around, and pushing your butt in the air.
Fluttershy nuzzled in to Rex's neck and whispered in to his ear. The dog excitedly jumped on his feet as you braced yourself. Soon enough, the weight of a large canine settled on top of you, his front paws pushing your shoulders down.
You felt his member hot dogging between you buns. Rex pulled back and pushed in again, this time poking against your balls. He tried once more and poked your perineum this time, making you whimper surprisingly needfully.
One last time he finally hit his mark, the head of his cock pushing against your anus. Slowly he started pushing himself in. You gasped as the head popped inside you gently. It pushed inside surprisingly easy, until suddenly it was nearly halfway in.
You panted hard in realization you were only a few inches away from hilting the big cock inside you. You wanted the rest.
A soft sigh made you look to the bed, where Fluttershy was lying on her back. Her eyes were fixated on you and your beastly lover, and her right hoof was between her hind legs, rubbing her sopping wet marehood. On her left side was a camera.
Your attention was taken elsewhere when Rex started in a slow hump. That shaft going in and out of you felt fantastic. So did the weight of him on top of you, his panting breath in your ear, and the soft moans of your loving marefriend.
You realized some of the soft moans came from you. There was no hope to silence yourself, and that hardly even mattered to you anymore. It just felt so good.
Suddenly Rex started slowing down more, pushing himself deeper inside with each slow thrust. Each time he pulled himself nearly all the way out, before pushing back inside, grinding against your prostate, pushing you closer to your climax.
And then, suddenly, you felt his furry hips push against your buttocks. You realized that you had managed to take the entire beast inside you. The realization made you give a long howling moan. The sound made Fluttershy's masturbation nearly furious.
Rex slowly pulled out again and pushed back in. You moaned again. The dog continued his movement, slowly building up speed. He was pulling a little above half of his length out before slamming back in. Each thrust, the head of his penis grazed your prostate, making you squeal.
Until finally, Rex pushed his entire length in, and didn't pull it out. He simply humped his body back and forth, grinding himself inside you. You felt the base of his penis swell, making you panic.
“W-what's happening?” you asked.
Fluttershy moaned. “He's- he's knotting you. He's cumming!”
Fluttershy's left hoof fell on the camera, the flash of the camera illuminating the room and making you feel vulnerable.
Then you felt it. Hot liquid, exploding from the tip of his cock, deep inside you. Rex kept humping, his swollen penis rubbing against your prostate.
And then you came.
With a long, loud, high pitch moan, your member spat out string after string of cum across the floor.
Your climax pushed Fluttershy over as well. She bit her lip and crossed her eyes, making that face you loved so much, as she squirted thick marecum on the edge of the bed and even the floor.
Your body went limp, but you couldn't fall to the floor, because you were tied to your canine companion.
For several minutes you had to hang under the dog, waiting for his knot to diminish.
Finally it did, and you fell to the floor, face first in your own cum. Fluttershy was next to you in a heartbeat.
“Are you okay?” she asked.
“I'm fantastic,” you sighed. “I love you.”
Fluttershy kissed the top of your head. “I love you too.”
You looked to the bed to see the picture that had fallen from the camera on the foot of the bed. You were wearing the same ecstatic expression as Flutershy in her pictures.
You were way too tired to move even an inch, so Fluttershy cuddled up next to you, with Rex warming you on your other side.
You were right about one thing. There was no going back.
