Spike vs the Bladder Stone

Spike was just about to finish up his morning chores when a sudden yelp of pain startled him, causing him to drop Obscure Unicorn History Vol. 3 from the top of the ladder and making a loud thud as it hit the hard floor below.

"Twilight!?" he exclaimed, suddenly worried about his best friend and housemate.

There was no reply.

He quickly descended the ladder and ran towards where he thought the sound had come from - the bathroom.

His heart beating rapidly, he knocked on the door.

"Twilight, are you in there?" he asked worriedly.

A pained moan came from inside he bathroom, followed by silence.

"Is everything all right?" he asked.

"It's... fine! Everything is... okay!" came Twilight's stammering voice from inside.

Spike was relieved to hear her voice, but it was obvious that something was wrong. She sounded like she was in great pain and on the verge of crying. He sighed deeply.

"Don't lie to me, Twilight. I can tell something's wrong."

She was silent for a while, before finally a reply came from the other side of the door. "I'm just... constipated. Yes, that's it. Don't come inside."

"I'll get the laxatives!" Spike quickly told her, and began to head for the kitchen.

"No! I'll be fine! Just... leave me alone!" she immediately exclaimed, causing him to stop.

He sighed again. "Oookay... if that's what you want." he said. He waited for a while, but no reply came, and he was just about to head back to finish his chores when her voice came from inside the bathroom again.

"Wait... don't go... Spike? Are you still out there?" she moaned.

"I'm still here." he replied.

 

------------

 

"I'm sorry, Spike." her voice sounded weakly from the other side of the door.

"What for?" he asked genuinely.

"I thought I could deal with this by myself, but I can't. I need your help, Spike."

"Of course I'll help, Twilight! What do you need help with?" he replied eagerly.

"I... I think you'd better come in..."

 

Not wasting a moment, Spike flung the door open to see Twilight sitting on the toilet.

Her mane was a ruffled mess, her forehead was dripping with sweat, and it looked like she had been crying.

The tip of her tail seemed to be dipping into the toilet bowl, and she either hadn't noticed or didn't care.

Upon seeing him in the doorway, her eyes began flooding with tears.

 

"Whoa, that must be a pretty bad constipation." Spike thought out loud.

"No, Spike... it isn't." she said. "I'm not sure, but from what I remember reading in medical books, I think it's a bladder stone. I can't get any pee out, and it hurts... bad..."

Spike listened intently, a worried expression on his face as his closest friend explained her problem. "So... what can I do to help?" he asked.

"I think it's gotten stuck in my urethra, and I need to get it out..." she explained.

"Your what?" Spike asked, scratching his head.

"My peehole, Spike." she explained, mildly annoyed.

"Oh."

 

----------------------------

 

"Can't you use your magic to get it out?" Spike asked.

"I... I can't. I can't concentrate enough to achieve the necessary precision in my current state." she explained.

"Maybe if we had a long smooth object, you could slide it in and try to dislodge it..." she suggested.

 

Spike thought for a bit, trying to think of any suitable objects they might have lying around, but everything he could think of was either too thick, too short or had pointy bits that could hurt Twilight.

"Can I take a look?" he asked, blushing a bit from embarrassment at asking his childhood friend such a thing.

She spread her legs and lifted her rump off the seat a bit, giving him a full view of her privates and teats.

He tried to suppress his arousal as he parted her nether lips with his fingers, but the pleasant smell of mare urine and crotch sweat was making it hard for him.

Probing around inside her for a bit, his claw finally found a smaller hole at the top of Twilight's vagina, and a weak yelp from Twilight confirmed that he had found the correct hole.

He tried to poke his finger further in, but he couldn't feel anything with his short index claw.

As he pulled it back out, it was followed by a trickle of dark pink-tinted urine.

"I can't reach it with my claw. It's too far in." he said dejectedly.

 

"Um... Spike..." Twilight said, suddenly staring at something below him with great interest.

He looked down to see to his horror that his penis had begun to grow hard.

"I'm sorry, Twilight! I didn't mean to..." he began flailing for an explanation. "I can't help it..." he finished lamely.

 

--------------------------

 

"No, Spike... I have an idea!" Twilight said, her face suddenly lit up despite her pain.

"I remember reading in a..." she blushed slightly and paused for a moment before continuing "...purely scientific book about dragon reproductive anatomy that dragon penises are long and thin."

"Yours isn't even fully grown yet, and it's already longer than your claws!" she added.

"What are you suggesting?" he asked Twilight, suspecting he already knew the answer.

"Well... I hate to ask you this, seeing as I'm like a sister to you, but..." she said, almost visibly shrinking with embarrassment. "... maybe you could try to use your penis to dislodge my bladder stone... unless you have a better suggestion."

 

Spike wasn't exactly proud of it, and had often wondered what Rarity would think if she saw it.

Even though he knew Twilight had seen it before, and even touched it when they were younger and used to take baths together, it still embarrassed him to be seen like this.

He was a teenage dragon now, dammit, and he wished he had a huge thick veiny stallion cock like Shining Armor's (which he'd of course only seen because Shining Armor also used to take baths with them when they were younger... his imagination may have exaggerated his memories of it a bit) that he could proudly show off to his marefriend.

Not that he'd ever had a marefriend anyway... Rarity always seemed to just brush him off as a little kid, and other mares rarely paid him any attention at all. Except maybe Fluttershy, but he wasn't quite sure how he felt about that.

 

Nevertheless, she had a point. He couldn't think of any better ideas, and he hated seeing his best friend in so much pain.

"Of course I'll do it, Twilight. A true friend always helps a friend in need." he said with determination.

A weak smile spread across Twilight's face.

 

---------------------------

 

"All right, let's do this." Spike announced.

Twilight spread her hind legs again, hoisting her butt off the seat again and pointing it towards him as he climbed onto the toilet seat.

"I'll need to get it fully erect and lubed up first." he explained, as he began to rub his shaft between Twilight's nether lips. The warm wet sensation of her pussy lips rubbing against him, combined with the musky smell of hay and urine rising up from the toilet bowl sent his arousal into high gear, causing his penis to rapidly grow to twice its length.

Twilight started at it in amazement as it continued to grow. Even she had never seen it fully grown, and now that he looked closely, Spike wondered if it wasn't longer than he'd ever seen it himself before.

Despite her pain, Spike could feel Twilight's pussy becoming more moist and slippery with marelube as he continued to rub against her lips. Apparently he wasn't the only one getting turned on.

 

As his penis showed no signs of further growth, he slid his hand in between her dripping pussy lips, coating it with her natural lube, and carefully smeared it across his entire shaft.

"Yes... be gentle, please..." she replied, a smile spreading across her face through her pained expression.

With his right hand firmly gripping his long pointy cock, he slid his left hand back inside her and locating her tiny peehole.

Using his claw to pull it open, he positioned the tip of his cock at its entrance and pushed.

She let out a moan of pain and pleasure combined as the tip of his penis slid inside her tiny urethral opening and began to push its way in towards her bladder.

The tightness of her peehole squeezing his dick felt incredible as he continued to slowly push inside her.

 

-----------------------------

 

Suddenly, about half way in, he felt the tip of his penis push against something hard, causing Twilight to let out a pained yelp. He tried to push a bit harder, but it wasn't budging.

"Ow! Stop! It hurts, Spike!" Twilight yelled, her eyes tearing up from the pain. "Maybe this wasn't such a good idea after all..." she mumbled.

"Just pushing doesn't seem to work, but maybe if I could get your urethra to expand around it..." Spike suggested.

"How?" Twilight inquired.

"I'm gonna try to pee on it. Maybe the pressure will stretch your peehole a bit."

Twilight stared blankly at him for a moment. "That... could work." she conceded.

 

Spike closed his eyes and tried to relax. Peeing with a full erection was easier said than done. Especially with a tight pony peehole squeezing it.

Finally, after imagining flowing water for a while he was able to relax enough, and he felt the flow starting from his bladder, making its way through his long erect penis and squirting weakly into Twilight's blocked peehole.

Twilight let out a soft moan at the sensation of his fluid starting to fill her obstructed urethra.

Spike pushed harder, adding force to the flow. As the narrow passage filled up, it became harder to pee inside her, and pink-tinted drops began to trickle out around his shaft.

He pulled his penis back out a little and thrust back inside, making sure not to go too far and hurt Twilight.

"I... I think it's working!" exclaimed Twilight excitedly. "I think I felt it move! Thrust harder!"

Taking her suggestion, he began to thrust in and out of her peehole, causing squirts pink-tinted urine to spray out with each thrust, and Twilight to moan louder and louder.

Her moans seemed to have changed from pain to pleasure. "Yes! Thrust harder and faster! I can feel it moving inside me!" she encouraged.

 

----------------------------

 

Suddenly, with what felt like a "pop", the pressure disappeared in mid-thrust, as the stone slid back into her bladder, causing Twilight to let out a loud moan of pleasure and relief

As his penis hilted inside her, Spike could feel the warm wetness of Twilight's piss engulfing him.

The pressure of Twilight's bladder, already stretched to its bursting point from being unable to pee and now with the addition of his own pee and the bladder stone, began to squeeze its way around his dick.

Twilight let out a gasp of pleasure as the sudden relief caused her to orgasm, dark pink-tinted urine spraying out around Spike's cock and splashing all over the toilet seat and floor.

An overpowering smell of urine and hay began to rise up all around Spike, further fueling his arousal.

The sensation of Twilight's flow massaging his dick quickly pushed Spike over the edge too, and he felt his body starting to spasm and thrust involuntarily against her as he shot load after load deep inside her bladder.

As their orgasms subsided, Spike slumped down, resting against Twilight's belly, both of them panting heavily.

 

"That was... intense..." Twilight said after a while, breaking the silence. "... are you peeing inside me?"

Spike nodded silently. He was too exhausted to pull out.

"Don't stop." she added.

 

Once they regained their breath, Spike pulled his now flaccid and rapidly shrinking penis out of her peehole with a soft wet pop, followed by a trickle of dark murky urine, and climbed down from the toilet.

Twilight readjusted herself on the toilet and a soft hiss started as she began to piss out the remainder of Spike's urine and cum.

She was positively surprised when with a loud plopping sound, the remnants of the bladder stone, which had apparently broken into several pieces shot into the toilet bowl.

 

-----------------

 

Later, after they had finished cleaning up and taking a shower...

 

"Hey, Spike..." Twilight said, suddenly looking up from a book she had been reading.

"What is it, Twilight?" he wondered.

"I was thinking..." she began. "How would you like to help me stretch out my urethra more often?" she asked.

"You know, just in case I get another bladder stone." she added, blushing a bit.

 

"Any time you want, Twilight." Spike replied, a grin spreading across his face.
