Author's Note
This is my story for the Kinktober 1st writing prompt, for the salirophilia fetish. As always, the prompt is in cursive, with my text continuing beneath it. It was a kinky kink to write about, but I hope you're going to like it! 
Wish These Were Yours
--He was handsome. His face was eye catching, high cheekbones, a strong jaw, beautiful sapphire eyes popping brilliantly with his white fur. The way his muscles rippled and clenched as he moved made her shudder and moan lewdly. She bit her lip hard as she gazed at his sculpted thighs that could crush a walnut. Her fur matted with sweat as love juices spilled out of her dripping cunt. Oh, she was so close, just a little more. She locked her purple eyes with his blue, doing everything she could to convey the pleasure he was making her feel in that single look.
The smile she got back pushed her over the top.
"I'm cummIIIINNNNNNGG!!!!" She grabbed her pillow and pressed it to her face as she screamed shrilly in bliss. He quickly went down, get splashed and drenched in her cum till he was completely bathed in it. It took some time for her to come back to reality from her pleasure high, but all good things come to an end at some point. She sighed, pulling the mare-cum drenched photo of a smiling Shining Armor when he was training in the royal guards to her eye level.
"If only you could be real." She smiled sadly, clutching the sopping photo to her chest. Her wings curling around her and the photo in a kind of sudo-hug. Slowly, with the picture of her unrequited love clutched to her chest, she finally fell asleep.--
The next day, Twilight woke up with the photo of her brother stuck on her coat. ”Not again!” she sighed, carefully pulling the ruined picture off her fur and burying it at the bottom of her trash bin. She had already developed so many copies of that picture that last hearts warming eve Spike had gifted her a new camera, thinking she was into photography because of how much time she spent in the darkroom. It was a nice gift though - as along everything else she had taken many new pictures of her brother as well.
She smiled at her memories as she took a shower to wash off the remains of her last photo. Feeling clean again, she stepped out of the shower, quickly realizing that she had forgotten to bring a towel with her. It wasn’t a big deal though, as she could just use the spare towel she had kept in her bathroom just for situations like this. She dried her mane and coat, before noticing something that had been hidden under the towel for who knows how long.
”A sock.” she thought aloud. ”It must have fallen from the laundry basket at some point. Oh well, I’ll just wash it with the next batch of laundry.”
She levitated the sock to place it in the laundry basket, stopping just short of dropping it in. Instead, she levitated it up to her face and inspected it more closely. It definitely wasn’t hers - it was way too big for her hooves. And it was white, while she was sure all her white socks were carefully accounted for in her perfectly organized sock drawer. Without thinking she gave it a sniff, her eyes sparkling with joy as the realization hit her.
”Shiny!” she sighed happily, sniffing the sock again. It had barely been worn, but she could identify the faintest trace of his scent in it. She closed her eyes as she gently stroked the sock against her chin, imagining her BBBFF nuzzling her. She stroked the sock from the other side with her hoof, but feeling its flatness hampered her immersion into the fantasy.
”I wish I could touch you, big brother” she sighed. ”Not just an empty sack with your-” she stopped. She was about to do something brilliant!
Giggling like a schoolfilly, she rushed straight to one of her less-used storage closets. ”Sports equipment - outdoor games - ball games...” she mumbled as she browsed the shelves, taking no time to find exactly what she was looking for. ”Aha! Tennis balls!”
She levitated the balls to her, giving them a quick look in anticipation of what was going to happen. Grinning widely, she slipped one ball into the sock followed by another, and with a little stretching and shuffling got them to sit at the bottom side by side. She beamed with pride as she admired her hoofwork - a big, juicy ballsack dangling right in front of her. With almost careful tenderness, she slowly bumped them with her nose and breathed in. She closed her eyes as let out a passionate sigh, nudging the makeshift balls with her muzzle. Imagining Shining Armor’s big, plump testicles on her face was already making her tail twitch.
Twilight opened her eyes to take another look at ”his” balls. They were pretty great already, but real testicles were always more egg-shaped than spherical. Out of curiosity, she used her magic to grab the balls and squeeze them, even though she already knew that tennis balls would just bounce back into their original shape once she let go.
”Ouch, that looks painful!” she thought as she made his nuts flex a little. ”Ow! Ow! Be careful with them!” she imagined her brother saying, squirming as his little sister held him by his tender bits.
Twilight grinned. ”Careful with what?” she said teasingly, squeezing the balls harder.
”My baAAALS!” her imaginary brother answered, his voice jumping as she teased him.
”Now why would I do that?” she said seductively, giving his nuts one more squeeze before moving her telekinetic grip back to the sock’s cuff to let them dangle freely. She patted them with her hoof, her pussy winking with excitement as the white ballsack swung back from the impact. She slapped them harder, now panting with excitement at the mental image of actually doing this to her brother. She leaned in again, feeling the balls bopping against her nose as she relished their warm, cottony texture.
”Now sit down and let me take good care of you...” Twilight said seductively as she gently set the sock down on the floor. The way they moved as they landed was so lifelike, she could practically see them resting between his legs. She pressed her forehoof on top of them, panting softly as she imagined squeezing her brothers most intimate organs.
”Ooh, Twily! That’s so hot!” she said in her best Shining Armor voice. She slowly put more of her weight on his balls, their fabric sack stretching as its contents flattened along the bottom of her hoof. She gasped as they reached their flattest point, imagining how helpless he would be if these really were his testicles. She couldn’t help but reach her other hoof between her legs and start stroking her dripping marehood, drooling and panting as she stared at the flattened sack beneath her hoof.
”How do you like that?” she asked, her breath getting faster as she pumped her hoof down. His balls flexed and squirmed, one of them plopping out from beneath her hoof and leaving its pair to compress down even further. Twilight took her soaked hoof off her vagina to stomp down on the escaped ball, her dripping pussy winking with desperate need. She turned and sat on his balls, moaning in pleasure as she felt their round shapes pressing against her rear.
”I'm gonna fuck your balls!” she gasped huskily as she started to gyrate her hips, the sock beneath her keeping his balls together as they squirmed beneath her plot and pussy. Her hoof found its way to her clit again, rubbing vigorously as she imagined grinding her marehood onto his testicles, his sack getting soaked with her juices as she pleasured herself with it.
”Shiny!” she screamed in throes of passion, throwing her head back as her gushing pussy clenched against the cotton scrotum. Her body spasmed, the sock beneath her stretching to its breaking point as one of the balls slipped all the way back to her plothole with the other still trapped beneath her vulva. She rode out her orgasm until she was spent, flopping down on her belly with the trapped balls plopping free from beneath her.
”Oh wow...” she muttered as her head gradually started clearing again. ”That was intense!”
The sock, now soaked nearly transparent by her juices was still in one piece, albeit a little stretched from its unintended use. Twilight smiled dizzily - it actually looked even more like a scrotum than before. She poked it gently, imagining just how tender his brother would be after having her ride his balls like that.
Twilight sighed with contentment. Having something of his to masturbate with had made the experience much more intense than she could have dreamed of. Getting up on still quivering legs, she picked the sock up to finally take it to the laundry, plopping the moist tennis balls into a wash basin along the way. She was going to get a lot of use out of this sock.
The End
