Fluttershy felt her cheek rubbing against the cold floor, her uncomfortably rigid wings being pushed down, the saliva dripping in to her hair. The panting of a large animal above her, the powerful paws pushing down on her neck, the filling warm sensation inside her. The large tapered cock scraping against her vaginal walls as it moved in an out in a furious rhythm.

She squealed as the animal pounded inside her, the suddenly expanding knot stretching her even further. She screamed as spurt after spurt of virile thick seed exploded inside her. Her legs trembled as she orgasmed at the thought of spending the next minutes tied to an animal...

Fluttershy woke up from yet another wet dream. She sighed sadly as she had to change her soaked bedsheets in the middle of the night for what felt like the dozenth time that week.

She passed Angel's new basket bed on her way out. The bunny normally slept in Fluttershy's bed, but had refused to do so ever since she started having trouble wetting the bed in her marejuices. Fluttershy didn't exactly object of course, it might have been better for him to sleep in his own bed, at least until she could get the mess sorted out.

She sneaked out the back door and dumped the bed sheets in to the dirty laundry basket. Last nights sheets were still there at the bottom. Fluttershy was tired of having to wash them literally every day.

She was just about to head back inside to put down new sheets and maybe even get some sleep before morning, when her eyes locked on to the kennel in her backyard. She walked past the open door to the smaller building and peeked in to see the only current resident.

Rex was curled sound asleep on the warm blanket near the back of the room. Guilty memories of what Fluttershy had done with him last week surfaced in her mind.

She had to but close her eyes and she could float back to that moment. To see the large member again, to smell it, to taste it again. To feel the hot cum covering her face. Fluttershy's hind legs ground together unconsciously as a heat woke between them.

She only had to wake him. Surely he wouldn't object to some more “help” from her. Turning the dream she'd had every night into reality was the simplest of things. All she had to do was nudge the sleeping beast inside the kennel and make the proposition.

She quickly shook the thought from her head. No, she couldn't do it. She shouldn't do it.

Fluttershy turned away before the images from her dream would have a chance to come back. She stepped directly in to a puddle of musky marejuices. She hoped against hope that Rex wouldn't be able to smell it once morning came.

She stopped by the laundry basket to quickly wipe her backside dry to the already dirty linens, before quietly trotting back to her bedroom. She changed in new sheets and laid down, hoping to get at least some sleep before her usual early rise.

Soon enough, she fell back in to haze of erotic dreams.

***

The morning came quicker than hoped for. Fluttershy woke, dumped yet another set of soaked linens in to the laundry basket, prepared breakfast for the critters about to wake up, and dinner for her nocturnal friends ready to come back home to get some sleep.

Then she went through the house waking all her animal friends. She started with Angel bunny, but only because he always took so much time to get up that all her other friends were already starting breakfast. Perhaps subconsciously, she left Rex last. More than any other morning, she had to fight against herself from going too far.

She couldn't help but notice him curiously sniffing the ground in front of the kennel before excitedly joining her for breakfast.

After breakfast Fluttershy could be found on the riverbank, going through the overfilled laundry basket with her, just a little too curious, otter friends.

In the afternoon, Rarity stopped by for tea.

“Oh, it's too bad we couldn't meet at the spa as usual, darling,” the sophisticated pony sighed. “Forgive me for saying this, but you look like you could really use some rest and relaxation.”

“Oh, it's okay Rarity,” Fluttershy replied. “I know I must look terrible. I haven't had enough sleep recently. Hopefully Aloe and Lotus can reopen before our next weeks meeting.”

“Oh, I just talked to them, they assured me the renovation would be done before weekend. And we won't have to wait to next week if you feel like you need it, we can go as soon as they're open.”

“Thank you Rarity,” Fluttershy smiled, “but I'm sure I'll manage until next week.”

“If you're sure, darling.”

A short silence followed, sullied only by the sound of teacups being emptied.

“If I may ask,” Rarity broke the silence, “what has kept you up at night?”

Fluttershy froze as a quick image of Rex mounting her crossed her mind.

“I-I wouldn't like t-to talk about it,” she stuttered as she cowered behind her hair.

“Maybe I could help,” Rarity insisted. “And whatever it is, talking about it with somepony will surely help at least somewhat.”

Fluttershy let out a weak eep from behind her hair.

“Alright, dear,” Rarity sighed. “But I'll be there the moment you feel like you can talk about it.”

Fluttershy nodded and caught movement from the corner of her eye. The door had opened and Rex had walked in.

“Why hello there,” Rarity greeted him. “What's your name?”

Rex barked happily, and nuzzled against her, hoping she might scratch behind his ear. And she did.

“His name is Rex,” Fluttershy said nervously.

Why was she nervous? She didn't have any reason to be nervous. Rex was just an animal in her care, right? She had introduced her animal friends to her pony friends before. It wasn't like she was introducing her special somepony or something…

“You're a big boy, aren't you?” Rarity cooed while petting him.

'He certainly is,' Fluttershy thought to herself.

Suddenly the dog pulled away from Rarity's hoof and padded to Fluttershy, who tried her hardest not to seem too nervous by his nuzzling. As she tried to pet him, he suddenly fell to the floor, exposing his tummy as well as his slowly hardening penis.

Both Rarity and Fluttershy gasped in shock.

For a second, the yellow pegasus was certain that their friendship was ruined. Then she saw Rarity blushing in embarrassment just as much as her, and realized she could still save herself.

“N-now Rex, that's v-very s-shameless of you,” she said, hoping she sounded convincingly lecturing, rather than turned on. “Y-you shouldn’t p-p-present yourself l-like t-that.”

“Yes, Rex,” Rarity agreed. “Why that is extremely uncouth of you. Such things should be reserved for your lover.”

Fluttershy had a small panic attack inside her head at those words. Thankfully Rex seemed to get the message, as he turned over and laid on stomach.

“I'm sorry, Rarity,” Fluttershy apologized. “Rex has been like this for a while now. He doesn't have a lover, and he's young and full of life and he just doesn't know what to do.”

“I understand,” the unicorn nodded. “I assume worrying about him is what has kept you up at night?”

“Yes,” she sighed. “Oh, I've tried just about everything.”

Fluttershy had never wanted to change subject so much, but couldn't think of a way to do so tactfully.

“I'm afraid I'm no help in such things,” Rarity admitted. “You know how I just leave Opal in your care whenever her heat comes.”

“I know, Rarity. Oh, I almost hope a nice girl dog would come to my care. Maybe then I wouldn't have to worry about him so much.”

“I'm sure everything will turn out alright in the end,” Rarity assured.

***

“Rex, I told you it was just one time.”

Rarity had finished her tea some time after the embarrassing incident and left back to her boutique. As soon as she had disappeared from sight, Fluttershy had taken Rex in for a stern talking-to.

“And it was very rude of you to present yourself like that in front of Rarity in any case.”

Rex whimpered sadly in response. Fluttershy reminded herself that she had to remain stern.

“You can't do that, Rex. WE can't do that. Do you understand? No matter how much we want to.”

She froze suddenly.

“I mean, you,” she stuttered. “No matter how much you want to...”

She dropped her head in thought and walked away. She stopped next to the chair she had sat on not five minutes ago, and noticed the small puddle of her lovejuices. She was certain Rarity must have noticed it as well.

***

As the days moved on, Rex built up more sexual frustration. Eventually he started to hump furniture again, and Fluttershy couldn't find it in her heart to scold him for it.

Fluttershy got worse as well. She replaced her sheets with a towel, and even considered wearing a diaper to bed. Unfortunately she didn't have the courage to buy such things, too afraid she'd be asked too many questions.

One day, Fluttershy wanted to simply enjoy a cup of relaxing tea, when Rex started having sex with her couch again. She tried not to care, but could feel the wetness spreading under her flanks.

After a few minutes, she could see his knot expanding before his seed exploded over her sofa cushion.

Fluttershy watched nervously as Rex walked out the door, presumably to take a nap in the kennel.

She gently set her cup on the table and walked over to the abused couch. The strong scent of animalistic sex was still in the air. She inhaled deeply and felt her soaked sex wink at the thoughts that ran through her head.

The cushion was covered in long ropes of sticky cum, and had to be cleaned sooner rather than later. She bent down and gave a long lick across the cushion, gathering as much cum as she could in her mouth. She would need to mop the floor as well.

In the night she woke up from yet another dream filled with beastly sex. Her bed was once more soaked in musky wetness, yet she was somehow still feeling horny. Her hooves fell on her winking marehood as she fell into her fantasies.

She ground her left hoof into her vaginal opening and mashed her right one over her clitoris. Wet noises and the sounds of her gasps and moans soon filled the room. She noticed Angel leaving the room in search of a peaceful sleeping place, but she hardly cared.

She whined desperately. Her hooves were not enough. She needed something inside her.

Quick as a flash, she was at her cupboards, where she procured a large dildo. It was equine in nature rather than canine, but perhaps it was better that way.

She quickly laid back down on the bed over her rigid wings with her hind hooves pushing her hips up. She pushed the flat head of the rubber phallus against her quivering vulva and in one fast stroke, she pushed it inside her, all the way to the medial ring.

A shaky squeal resonated through the house. Downstairs, a tired bunny debated whether to go sleep outside.

The pegasus weakly pulled the fake cock out of her and forced it back in even deeper. Her hips bucked against the penetration, making her lose her footing. The cock slipped out of her as she laid on the bed panting.

She quickly recovered, pushing herself on her hooves. She grabbed the wet dildo with her mouth and pushed the base of it against her beds headboard. The powerful suction cup grabbed the wood harshly, leaving the rigid cock hanging in the air.

She backed in to the head of the penis, and laid her head down on the wet bed, reaching back with her hooves. It was hard to guide the dildo to her opening with trembling hooves, but she managed it.

She slammed her flanks backwards and howled as her eyes rolled up at the feeling of being filled again. The medial ring of the toy stretched her inside walls wonderfully. She moved forward, pulling the toy out of her until only the tip remained inside, before slamming back.

She went even deeper, the ring grazing over her g-spot, in a way that nearly made her climax. If only it was warm, if only it was real. If only it was him.

Her legs shivered, threatening to drop her before she could find satisfaction. Slowly she pulled her trembling body forward, until only the slightly flared head of her unfortunately silent companion stayed inside her.

Once more she flung her rump backwards. Once more the medial ring slid over her pleasure button. Once more her cry of ecstasy echoed through the house, followed by a wet slap of her flanks against the wood.

She reached climax as all the rubber penis had to offer filled all she had to fill. A torrent of cloudy marecum exploded around the phallus, soaking the headboard. And the only thought in her mind at that moment was; I want it to be him.

The cock slipped out of her with a loud shlick as she fell on the bed, legs sprawled. She panted hard for several minutes, trying her hardest to enjoy the afterglow. Before long, she pulled her tongue back in to her mouth, pushing herself up on shivering legs.

It was not enough.

“Rex?”

The dog woke to the timid voice of his caretaker. The shy equine stood trembling in the door to the kennel, drooling, her face red, wings fluttering and tail twitching.

“Do you trust me?”
