Watch where you sit
Slowly the door of the Sweet Apple Acres barn creaked open, letting a ray of light into the recently constructed building. A small, purple dragon carefully looked around before he crept inside, closing the door again behind him. It was applebuck season and the workload this year was gigantic. Even though Big Macintosh could help this year and even cousin Braeburn was there to help, he and the ponies still had to help. Spike wouldn't have any of it though, he was a baby dragon and needed his rest.
He spotted a nice, big bit of hay lying on the floor, large enough to hide inside. Even though he couldn't help much, Twilight insisted that he did something other than sleeping. Spike felt defiant today though, so he snuck away at the first opportunity and headed into the barn. Still, there was the problem that he would be discovered and chewed out if they saw him sleeping in here, so he decided to hide in the hay lying there. Snuggled into the warm hay, Spike soon fell asleep.
After an hour or so, two ponies were walking towards the barn, one of them limping slightly. Twilight was escorting Braeburn to the barn where he could rest. When he bucked a tree he slipped slightly, causing a sprain in his ankle. "Seriously Braeburn, you bucked apples for years, how did this happen?" Braeburn was slightly emberassed. "A foul apple has fallen off the tree and I stepped on it." Twilight sighed and opened the barndoor. "Well, sit down here and rest for a while, we already did most of the harvest for today anyway." Braeburn nodded towards her and limped inside while Twilight returned to the orchard.
Spike woke up as he heard somepony coming in and silently cursed when he heard Twilight. He kept very still as he heard the clopping of hooves. Why did Braeburn have to sprain his ankle, now he would be stuck here until he left. Spike held his breath as the hoofsteps got closer, then an idea hit him. Maybe he can sneak past Braeburn. Carefully the small dragon peeked out of the hay, only to notice a shadow descending upon him.
Braeburn has decided to sit down for a while, he spotted a comfy looking pile of hay somewhere in the back, which would provide him with a good seat. He limped over to the hay and turned around, missing the sound of rustling underneath his rump. So, not noticing Spike under him, Braeburn plopped his flanks on the ground, directly onto the little dragon.
The last thing Spike saw before everything went black, was a tight, fleshy ring. Then he could feel how he was pushed into something wet, soft and tight. Immediately he started to struggle against the confines of his new prison. It did not take long for him to realize where he was. Braeburn has sit down right on top of him and now he was inside of the stallions rectum.
As Braeburn felt something invading his anus it was already too late to stop and whatever he sat on went right into his intestine. He whinnied loudly and rose again, only a purple tail sticking out of his rear right now. Whatever he sat on was moving and Braeburns cheeks flushed at the actually very pleasant sensation. His stallion cock emerged from his sheath until it reached full lenght.
Spike continued to struggle but it seemed like everything he did only made him slip in even further. He did not know that his wild struggles inside the intestine only gave the stallion a very good time. Braeburns knees buckled and he fell on his side before rolling onto his back, his cock twitching with pleasure.
Finally, Braeburn whinnied again and white semen sprayed from his cock, covering his belly all the way up to his neck with the sticky seed. Braeburn still laid on his back, twitching as the movement inside of him continued. Eventually, whatever was shoved up his rear arrived at his stomach and settled there, still moving. Now Braeburn could hear a voice. "Let me outta here!"
Braeburn was shocked as he recognized the voice. "Spike? Is that you?" He asked. Now he was even more emberassed since he knew who went up his ass. "What were you doing in that hay?"
The little dragon blushed slightly, now he had to admit it. "Well, I hoped I could get out of work. Don't say anything, you sat on me and pulled me up your ass." There was a minute of awkward silence until Spike spoke up again. "So.... what now?"
Braeburn was thinking for a moment. "You really can't stay in there, even though you should be safe. Dragons have thick scales. Maybe I can try to cough you up." Then his look fell to his belly, where his own seed was starting to dry up. "But first I need to clean up a little."
After cleaning himself up and hiding the evidence, Braeburn went to a secluded corner of the barn and started to heave the little dragon up. It was not easy due to Spikes size but neither of them wanted to try the other exit first. Eventually though, Braeburn managed to spit Spike out again, letting him fall onto a small pile of hay. The little dragon looked up at the stallion, covered in slobber and slime. "Braeburn... we will never speak of this again."
The stallion could only nod in agreement.
